A truck backed into gas station pump

June 30th, 2009 Administrator 1 comment

truck-backs-into-gas-pumpA gas station pump burst into flames after a truck backed into the pumps. The fiery explosion threatened a small child - and the whole incident was all caught on video.

NewsChannel 5 reporter Jeff Tang talked to the man who saved the day.

Each day, Casey Kahasay adds to a remarkable streak when he shows up for work at his Shell gas station on the corner of Tiny Town Road and Fort Campbell Boulevard in Clarksville.

Since 2006, Casey has not taken a vacation - not even on a weekend.

“I’ve never had a day off,” he said.

Casey deserved one after what happened at his store Sunday night.

“I was nervous,” he said. “I never had that experience before.”

Just after 10 p.m. Sunday, one of Casey’s regular customers stopped by to fill her tires up with air. As she walked into the store for change, the truck started moving backwards with her 2-year-old child in the back.

“I see the truck moving back and it hit [the pump],” Casey said.

Video surveillance showed a burst of flames behind the truck.

Casey sprang into action. He told the woman to grab the child while he brought out fire extinguishers.

“The flame was from the pump to the truck - to a little bit higher,” said Casey.

As he fought the fire, witnesses like Rich Palleschi watched in horror.

“I was fearing the worst - not just the pumps, but the tanks underneath. Plus, I run a [fireworks store} right across the street,” said Rich.

It took three extinguishers and a garden hose, but Casey held off the flames long enough for firefighters to arrive and finish the job.

“That’s Casey. That says ‘Casey’ every day. I’m not surprised by it. He doesn’t want a pat on the back for it - that’s something he would have done for anybody,” said customer Al Ellison.

So why did Casey risk his life for a stranger’s child? He has his own children - ages 7 and 4.

“That was my life. I work hard for this store because of these two kids,” he said.

Amazingly, no one was injured during the explosion. By mid-afternoon on Monday, the other pumps were back in working order at Casey’s Shell station - and his attendance streak continued.

“Still, I’m going to work - got to keep going,” he said.

Police advise children should not be left in a vehicle by themselves when adults go into a store - even if just for a brief time.

Pump used in your home - Sump Pump

June 18th, 2009 Administrator 3 comments

Sump pumps really aren’t very complicated devices compared to some of the other things you have in your home. And yet their service can save you thousands in water damage, should flooding occur. Yes, the sump pump is the unsung hero of our basements.

1. Sump pumps generally fall into two categories:

submersible and pedestal. Both of these models serve to pump water out of the sump and away from where it can harm your property. Both kinds of sump pump sit at the bottom of your sump and activate based on a float switch that tells them when the water level has risen to a certain height. In fact, the parts of a sump pump are pretty much standardized these days. The main difference is that the pedestal sump pump has a motor that sits atop a pedestal, which stretches out of the pit and in plain view. This motor is supposed to remain dry, and the visibility can make repair a bit easier.

2. Power.

For most households, a 0.33 horsepower sump pump will serve adequately. If you feel that your basement suffers greater amounts of water than the average household basement, then you can use a 0.5 horsepower sump pump - it can pump more gallons per minute (standard unit of flow rate) and can pump the water higher.

3. Drainage.

In older homes, sump pumps are often set up to drain into places that, by today’s laws, are illegal. Check your local laws to make sure that your sump pump empties legally; often the older sump pumps are set to pump into the sanitary sewer (often illegal) as opposed to a storm drain or other legal setup. I’ve seen sump pumps that just pump the water right out onto the street, which can also be illegal. Check your local sump pump regulations to make sure your sump pump removes water at a legal distance and to a legal destination.

4. Maintenance.

Sump pumps don’t often require maintenance, but you must check on them once in a while. Once you see the evidence of a sump pump problem, all too often the damage has already been done. It’s best to be familiar with some of the main causes of sump pump failure so that you can occasionally check the condition of the sump pump and prevent that awful water damage. Any time you perform maintenance on the sump pump, unplug it!

  • Check once in a while to make sure that the switch float inside your sump pump is floating freely; if it gets stuck, the sump pump won’t be able to detect the water rising.
  • A plug in the opening to a sump pump can obviously make it difficult for a sump pump to fulfill its vital duty. Check your sump pumps occasionally to make sure that screens and openings aren’t clogged.
  • Clean out the sump pit occasionally as well, since it accumulates dirt.
  • Compressed air trapped between the pump and the check valve can impair a sump pump’s performance or simply render it inoperative. This is a pretty common problem in sump pumps with a solid pipe that leads to the check valve. If your sump pump has a solid pipe there, cut about a 1/8-inch hole through the side of the pipe within the sump; this will prevent compressed air from becoming a potential problem for your sump pump.
  • Power outage will prevent any sump pump from working if it runs only on electricity. If your drainage problems often coincide with power outages, then a plug-in sump pump spells disaster for you. Consider buying a sump pump with backup battery power instead, or one that runs entirely on battery power.

The Water Pump Story

June 17th, 2009 Administrator No comments

Crawling on burnt hands and knees across the blistering hot sand, his throat rasping in searing pain with each seemingly last breath, with only about a day more travel before he reached town, a miner came across a cabin. In the cabin was a rusty water pump. The pump handle was in the up position, as though it was waiting for him. Tied to the handle was a goatskin flask with at least a cup of water in it. Attached to the flask was this note.

Dear Traveler, I know how bad it is for you. That’s why I drilled the well and built this cabin. You may drink the water and it will see you to safety, or, you can risk pouring it down this rusty pump so as to wet the leather washers thereby enabling you to prime the pump and drink your fill and refill the flask for the next needy traveler.

The variables seem obvious. Far from any desert, with our thirst quenched, we are able to sit righteously and detached and weigh all the factors. For example, we might think, “It would be stupid to pour the water down a possibly dry well.” “What if the washers were so dry that they had cracked and broke?” “I know, I’ll drink the bag of water and come back later and replace it.”

Unbeknownst to the miner there are several fundamental generating principles at work. The miner drinks the bag of water and promises himself to return and leave much more than a small flask. However, he gets bit by a scorpion and dies not 100 yards from town. You see, he dismissed the thought that while he was gone another traveler may have needed the water.

What’s the purpose of this story here in a web site about communication?

Well, (no pun intended) it’s about integrity as a communication variable. When something doesn’t go as envisioned one can’t be certain if it has to do with one’s integrity or simply a communication problem until one has eliminated the outcome as being a consequence of an out integrity. “H’mm. lets see. What could this broken agreement be about?” If nothing comes up it’s most likely has to do solely about your agreement making skills. For most, the question reveals an incomplete, an unacknowledged perpetration.

For example: Take the case of a mechanic “past due” for his monthly house rent payment, who opts for his own survival. The mechanic has valuable tools or a TV that he could sell so that his landlord doesn’t have to sell something to meet his own monthly mortgage payment to the bank. But the mechanic thinks, “I’ll keep my tools so I can make some money so I can then pay my rent.” He doesn’t realize that he has had this survivalist philosophy, this ground of being, of his own survival being more important than his word, for many years. All people who file for bankruptcy have this survivalist philosophy. It’s what brings about their failure.

In the study of communication it’s imperative that you study the subject of integrity. Look now to see what your philosophies are.

1) Do you think there’s a possible connection between the fact that the mechanic doesn’t have enough money to pay his rent and the fact that all along he’s not been committed to keeping his agreements?

2) Is there anyone who would say you are surviving at their expense?

3) Do you have any broken financial agreements that are causing others hardships?

Water Leaders Tour American River Pump Station in Auburn

June 17th, 2009 Administrator No comments

amerrivpumpstation2AUBURN — Water industry leaders from across Northern California gathered Friday (June 12) in Auburn for a business meeting and tour of the Placer County Water Agency’s innovative American River Pump Station.

The occasion was a joint meeting of the Association of California Water Agencies (ACWA), Region 3; and the Mountain Counties Water Resources Association (MCWRA). Co-hosted by PCWA and the Nevada Irrigation District (NID), the meeting attracted about 80 people to the The Ridge Golf Club and Event Center in Auburn.

Featured speakers were John Woodling, executive director of the Sacramento-based Regional Water Authority (RWA) and Victoria Whitney, chief of the Division of Water Rights of the California Water Resources Control Board.

Woodling’s presentation focused on the governor’s call for a statewide 20 percent reduction in urban water use by the year 2020. He said a “one size fits all” approach to water conservation will not work and that conservation can best be accomplished by local agencies. “Under our existing regional plan we will achieve a 20 percent reduction by 2025,” he said.

Whitney provided an overview of the state’s role in the often complicated world of water rights. She explained the many different kinds of water rights in California, including “area-of-origin” rights held by many of the mountain counties represented at the meeting.

Following the business meeting, guests traveled to the American River canyon for a guided tour of the PCWA American River Pump Station. The $76 million pump station and river restoration project is designed to supply American River water to Placer County while restoring the American River to its natural channel at the site where an Auburn Dam was once planned.

Completed in 2008, the project combines a whitewater channel that allows recreational use with an adjacent underground diversion structure built into the river bottom. The horizontal screen diversion reduces sedimentation while providing for the safe passage of both fish and recreational watercraft.

“This project returned three miles of river to the public, and PCWA regained access to a critical water supply,” said PCWA Deputy Director of Technical Services Brent Smith, who led the tour.

Based in the Placer County seat of Auburn, PCWA holds rights to 280,000 acre-feet of water and serves more than 250,000 people. The agency operates the Middle Fork American River Project which produces hydroelectric energy as well as water for home, business and agricultural uses.

A History of the Vacuum Pump

June 9th, 2009 Administrator 7 comments

The vacuum pump is a genius invention that plays a role in many parts of our lives. Vacuum pumps are used in our air conditioning units, in our cars, in our airplanes, and even in some of the medical processes used today. Though it was a technology that took some time to develop, comparatively speaking, it is a technology that was well worth waiting for.

The initial vacuum pump was designed in the 1650’s by a man named Otto van Guericke. This pump created a vacuum by pulling gas molecules from a sealed space. Otto Guericke’s theory lay in the belief that if two pieces of a whole, say a sphere, were connected and the air was sucked out of the sphere, nothing would be able to cause the two halves to separate. His theory was proven correct and, initially the response was good, with more tests and demonstrations being performed throughout the 1650’s. Over time things trickled off, however. Vacuum pumps were still tested but not widely used because they did not produce enough suction.

In the late 1690’s a vacuum pump was patented in England. This pump was known as the Thomas Savery pump. Many modern pumps have been designed after this one pump.

Experimentation and testing with vacuum technology continued until 1855 when Heinrich Geissler created the mercury displacement pump, which was even better than the Guericke’s invention.

Fast forward a few hundred years to where vacuum pumps are a part of our everyday lives. As mentioned before, the technology took time to develop properly, nearly three hundred years, but it was well worth the wait. You’ll find vacuum pumps being used by firefighters in their rescue missions, by doctors administering radiotherapy, in freeze drying processes, and throughout sewage systems.

You’ll also find a bunch of different types of pumps, ranging from low and medium, to high pressure pumps. Low and medium pumps are more simply made. Medium pumps are used in aircraft as part of the heading and altitude systems while low pressure pumps are often part of the air conditioning units. High pressure pumps are usually those used in hydraulic systems. They are more complex than low and medium pressure and are usually made custom for each job they are required for.

Most of the history of the vacuum pump centers on testing and perfecting the science, building upon the discoveries of earlier inventors. Three hundred years is a long time to master the art of creating a vacuum pump, and the time has been put to good use. The pumps have been altered and perfected, and are now being put to good use.

Centrifugal pump designs

June 5th, 2009 Administrator 6 comments

The overwhelming majority of contractor pumps use centrifugal force to move water. Centrifugal force is defined as the action that causes something, in this case water, to move away from its center of rotation.

All centrifugal pumps use an impeller and volute to create the partial vacuum and discharge pressure necessary to move water through the casing. The impeller and volute form the heart of the pump and help determine its flow, pressure and solid handling capability.

An impeller is a rotating disk with a set of vanes coupled to the engine/motor shaft that produces centrifugal force within the pump casing. A volute is the stationary housing (in which the impeller rotates) that collects, discharges and recirculates water entering the pump. A diffuser is used on high pressure pumps and is similar to a volute but more compact in design. Many types of material can be used in their manufactire but cast iron is most commonly used for construction applications.

In order for a centrifugal pump, or self priming, pump to attain its initial prime the casing must first be manually primed or filled with water. Afterwards, unless it is run dry or drained, a sufficient amount of water should remain in the pump to ensure quick priming the next time it is needed.
As the impeller churns the water (see figure above), it purges air from the casing creating an area of low pressure, or partial vacuum, at the eye (center) of the impeller. The weight of the atmosphere on the external body of water pushes water rapidly through the hose and pump casing toward the eye of the impeller.
Centrifugal force created by the rotating impeller pushes water away from the eye, where pressure is lowest, to the vane tips where the pressure is highest. The velocity of the rotating vanes pressurizes the water forced through the volute and discharges it from the pump.
Water passing through the pump brings with it solids and other abrasive material that will gradually wear down the impeller or volute. This wear can increase the distance between the impeller and the volute resulting in decreased flows, decreased heads and longer priming times. Periodic inspection and maintenance is necessary to keep pumps running like new.

Another key component of the pump is its mechanical seal. This spring loaded component consists of two faces, one stationary and another rotating, and is located on the engine shaft between the impeller and the rear casing (see figure below). It is designed to prevent water from seeping into and damaging the engine. Pumps designed for work in harsh environments require a seal that is more abrasion resistant than pumps designed for regular household use. Typically seals are cooled by water as it passes through the pump. If the pump is dry or has insufficient water for priming it could damage the mechanical seal. Oil-lubricated an occasionally grease-lubricated seals are available on some pumps that provide positive lubrication in the event that the pump is run without water. The seal is a common wear part that should be periodically inspected.

Regardless of whether the application calls for a standard, high pressure, or trash every centrifugal pump lifts and discharges water in the same way. The following section will point out design differences between these pumps.
Standard Centrifugal Pumps
Standard centrifugal pumps provide an economical choice for general purpose dewatering. A number of different sizes are available but the most common model offerings are in the 2 to 4 inch range with flows from 142 to 500 gallons per minute (GPM) and heads in the range of 90 to 115 feet.

these pumps should only be used in clear water applications (agricultural, industrial, residential) as they have a limited solid handling capability of only 10% by volume.
The impellers typically use a three-vane design (see figure below) and the volute is compact, preventing the passage of large solids. The rule of thumb is the pump will only pass spherical solids 1/4 the diameter of the suction inlet.
One advantage these pumps have over comparably sized trash models is their low initial cost. There are several reasons for this difference. Lower horsepower engines are utilized that are smaller in size and more fuel efficient. The mechanical seals, since they are not subjected to harsh working conditions, can be made of less costly material. Additionally, the casings are smaller and have fewer machined parts that when combined with the smaller engines make the pumps much lighter in weight.

High Pressure Centrifugal Pumps
High pressure centrifugal pumps are designed for use in applications requireing high discharge pressures and flows. Contractors may use them to wash down equipment on the job site as well as install them on water trailers. Other uses include irrigation and as emergency standby pumps in areas where there is a high risk of fire.

Typically these pumps will discharge around 100 GPM and produce heads in excess of 240 feet. The pump may have a 2 inch suction port and up to three discharge ports of varying size for added versatility. The impellers used on these pumps are a closed design (see figure below) and not open like those used on other types of centrifugal pumps. Similarly the diffuser is more compact than a regular volute in order to generate the high discharge pressures. These pumps by design are not capable of handling any types of solids or even sandy water, Silt, sand or debris would almost immediately clog the pump if allowed to enter into the casing. Additionally, the impeller and diffuser may be made of aluminum rather than weather resistant cast iron since they are not subject to abrasive materials. It is recommended that a mesh net always be placed over the suction strainer if the pump is being used in dirty water.

Trash Centrifugal Pumps
Trash centrifugal pumps get their name from their ability to handle large amounts of debris and are the preferred choice of contractors and the rental industry. The most common sizes are in the 2 to 6 inch range producing flows from 200 to 1,600 GPM and heads up to 150 feet.

The rule of thumb is that a trash pump will generally handle spherical solids up to 1/2 the diameter of the suction inlet. Solids (sticks, stones and debris) flow through without cloggin making themideal for the water conditions typically found on job sites. Trash pumps handle up to 25% suspended solids by volume.

Trash pumps offer another benefit in that they can be quickly and easily disassembled for service or inspection. While standard pumps require special tools that are not always available the inside of a trash pump gousing can usually be accessed with common tools.

Customers occasionally ask why a trash pump costs more than standard centrifugal pumps. One big reason is that higher horsepower engines are neeed for trash pumps. The impeller is typically a cast iron two-vane design (see figure below) and a large volute is required to handle the higher volume of water and debris. The mechanical seal - like the impeller and volute - is selected for its abrasion resistance and more parts are machined for the casing. While there is a higher initial cost it must be noted that is is recovered through the reduced maintenance over the life of an often used pump.

How to choose the Right Pump

June 4th, 2009 Administrator 3 comments

choosing-the-right-pumpChoosing the correct pump for an application should not be difficult if a few basic preliminary steps are followed.
• Volume and pressure requirements of the system
• Type of material being pumped – oil, fertilizer, insecticides, chemicals, and at what temperature
• How the pump will be driven and at what speed – PTO, engine, electric motor or hydraulic motor
• Check HP requirements of power unit for system pressure and volume

Diaphragm Pumps
A diaphragm pump is a positive displacement which means flow stays constant with speed. Flow is also variable with change of speed. This type of pump is reliable and compact compared to other pumps that have similar flow and pressure ratings. These pumps are excellent for agriculture, industrial, lawn care and nursery requirements because of their adaptability to spraying conditions.
ADVANTAGES
• Wide range of flow and pressure specifications
• Low maintenance and almost wear-free operation
• Self-priming
• Handles wide range of materials that would damage other pumps such as corrosive chemicals, wettable powders and other abrasive solutions.

Roller Pumps
A roller pump is similar to a vane pump except it utilizes multiple rollers in place of sliding vanes. Its unique design adapts to a variety of spraying applications, especially for the lower PTO speed requirements of agricultural spraying systems.
ADVANTAGES
• Low initial and maintenance costs
• Operates efficiently at PTO speeds
• Good priming characteristics
• Compact size in relation to capacity
• Easily mounts

Centrifugal Pumps
Centrifugal pumps are very popular because of their versatility. They provide high capacities and handle abrasive and wettable powders. Centrifugal pumps require higher operating speeds which make them ideal for small engine applications of liquid transfer.
ADVANTAGES
• Handles suspensions well
• High capacity
• Low maintenance
• Low pressure characteristics, pressure only needs to be controlled by by-pass valve
• Some designs can handle solids,

Piston Pumps
A piston pump is a positive displacement pump which means it delivers variable output in proportion to its driven speed. It also develops the higher pressure needed for washing equipment, injecting chemicals, and other agricultural and industrial needs that require long life and dependability.
ADVANTAGES
• Wear resistant
• Positive displacement
• High pressure capability
• Good priming characteristics
• Handles various chemicals, wettable powder suspensions, and other abrasive liquids

Pressure Washer Components
choosing-the-right-pump-1

Pump
Creates flow in the system
Nozzle
Sized to the pumps output flow to obtain desired output pressure. Using nozzles, with different orifice sizes, with a fixed flow rate, can change output pressures.
Unloader Valve
Pressure actuated plunger bypasses flow under low pressure to the intake side of pump when the trigger gun is closed. This relives engine load. Opening trigger gun allows unloader to redirect water to the gun.
Pressure Reducing Valve
Lowers inlet water pressure to allow upstream chemical injection to operate.
Pulsation Dampener
Reduces water hammer and smoothes output flow reducing wear on components,
Bypass Hose
Directs water from unloaded to inlet side of pump.
Strainer
Prevents foreign matter from entering system.

Pressure Washer with Downstream Injection

Chemical Injection
Chemical injectors provide a mechanical means of introducing chemical into the water stream. The addition of chemical provides better cleaning results while saving time and water consumption. This chemical can be introduced into the water stream by either upstream (before the pump) or downstream injection.

Methods of Chemical Injection
Upstream

1. Three way selector valve to select between chemical tank and rinse water.
2. Chemical injector on inlet.
3. Pump mounted injector.

Downstream

1. Chemical injector on outlet side of pump.

Operation
Upstream
Upstream chemical injection allows user to inject the chemical at high pressure. Chemical is metered or controlled by a valve mounted at the injector. Operator must return to pressure washer to operator injector.
Downstream
Downstream injection allows operator to control injection at the gun. Chemical is introduced into the water stream at a reduced pressure (normally less that 250 PSI) by increasing nozzle opening size. At reduced pressure, water passes through a venturi drawing chemical with it to the gun. At high pressure water still passes through the venturi but it closes a check valve preventing chemical flow.
