How does a Well Pump Work?

October 19th, 2010 Administrator No comments

how-does-a-well-pump-work

For many people around the world, water is not piped in by the local water company; instead, it is pumped from a well. Wells range in size and depth and the amount of water that is available. Some wells are built for a single family to use, others by an entire village. While the most basic way to retrieve water from a well is to use a bucket that is tied to a rope, a more efficient way to retrieve water is by using a pump.

The most common pump used with wells today is called the submersible pump, specifically pumps that run on electricity. Electrical submersible pumps are usually very reliable and effective for pumping water from a well. It should be noted that if you don’t have a well, you might still be familiar with an electrical submersible pump to remove drainage from a flooded basement or home.

Electrical submersible pump are hermetically sealed. This means that no external water or substances can enter the pump. If water entered the inner working of the pump, it would most likely short it out and ruin the internal parts.

Some of the components found in an electrical submersible pump include the motor, the equalizer, the intake, the pump itself, and the cable to feed electricity to the motor to drive the pump. There are many types of pumps available; however, in practically all electrical submersible pumps you will find a centrifugal pump. In an electrical submersible pump, water flows into the pump (this is called suction) and then flows out of the pump (this is called discharge).

In a centrifugal pump, the direction of the discharge is at a right angle to the flow of the suction. When water flows into the pump, it moves onto an impeller (centrifuge type device). This device spins very quickly around an axis and the water is discharged at a greater rate and pressure than when it enters into the pump. The reason for the extra energy is centrifugal force. This allows water from the bottom of a well to be pumped up to the top of the well with relative ease.

While electrical submersible pumps are extremely popular and perfect for most wells, they have difficulties working properly in areas that have lots of sand or sediment. However, since these pumps are usually hermetically sealed and have only a few moving parts, they are fairly easy to fix and maintain for prolonged use.

Many electronic submersible pumps are built specifically for home use, especially for homes that are not connected to municipal water and sewer resources. Electronic submersible pumps are not very technically complicated and thus are usually affordable.

It should be noted that although they are a great option for use in the United States and other developed countries around the world, since they do require maintenance from time to time, electrical submersible pumps are not the best to use. Also, replacement parts can be difficult to obtain.

All About Piston Pumps and Their Beneficial Operations

September 26th, 2010 Administrator No comments

all-about-piston-pumps-and-their-beneficial-operations

Piston pumps are there almost everywhere in our lives. But, its just that we are not aware of their existence or their usefulness. The axial one are used almost everywhere but they are most useful in the aerospace industry.

Well, before talking about this and its use in the various industry sectors, let us know a few basic things about them. This are nothing but positive displacement pumps that have a number of cylinders arranged in a circular pattern within a cylinder block. This block known as a rotor or a barrel, this is a key component in their assembly. The size and surface texture of this cylinder bores is critical to proper performance and life of the assembly.

This come in many varieties that include axial radial inline form, radial-piston form, and also in plunger. They also differ based on the type of component they are used like bronze, brass, steel, stainless steel, iron, nickel alloy, or other material.

These pumps are used in lower pressure applications, unlike plunger pumps which are high pressure pumps. Indeed, this provide an excellent solution for many hydraulic oil pumping applications. However, the pumps used in these operations have iron cylinder and piston with a steel piston rod.

Whatever model of piston pumps or pressure washer pumps you intend to buy, always go for manufacturers whose products are acknowledged for high functionality, low power consumption and excellent durability. They should also come with rounded construction that has no drum-type surfaces to amplify noise.

Also, as in a centrifugal pump where restriction or increased head creates reduced flow, a piston pump has a very flat flow performance curve. This may result in blockages, which is very hazardous. Hence, use only piston pumps that have safety devices such as unloaded valves.

A Little Information Regarding Concrete Pumping

September 26th, 2010 Administrator No comments

a-little-information-regarding-concrete-pumping

There are many businesses, as well as home owners, that find themselves needing to place concrete for one reasons or another. There are many ways of accomplishing this that are both expensive as well as very time consuming. Because of this we will be covering a little information regarding concrete pumping. If you need to lay in the near future, you should read on.

The best thing about pumping concrete is that is is most of the most economical ways to place the substance. It also happens to be a much quicker and efficient way as well. Anybody who has ever had to lay concrete before is probably well aware of how very expensive such a service can run. This is why so many people are trusting in this method for all of their needs.

Another really great thing about pumping concrete is that there many types of machines that can accomplish this task. This allows the client a lot more flexibility as well as the opportunity to best determine the type of device that would most economically serve their needs. It is of a high level of importance to take a much closer look at some of the popular devices that serve this purpose.

The boom pump, is easily, one of the most common used machines for pumping concrete. Most professionals refer to at as an “all in one” solution. This is because the boom pump is a completely self contained machine that includes not only a truck that is equipped with the proper frame, but the actual pump unit itself. This machine obviously works well for very large jobs.

Another type of machine that is very popular within this field is often referred to as the line pump. This is a self contained vehicle and machine that has a pump installed, however it is important to note that it is a great deal smaller than the boom pump vehicle that was previously mentioned. This type of machine is obviously desired for smaller jobs and has many possible applications.

It is important to consider that a boom does not need to exist within a vehicle. The actual boom without the aid of a vehicle is often utilized and it is referred to as a “placing boom”. This allows the workers to place lines in designated areas and attach the placing boom to these areas. This type of equipment can serve a great deal of possible applications.

Keep in mind that in order to have this equipment used properly, you should hire the services of a professional and qualified service that specializes in pumping concrete. Because most major cities have so many companies that fit this description, you should be able to do a fair amount of comparative shopping that will allow you to find the most qualified yet cost effective option.

After learning more about concrete pumping services, you might have an easier time shopping for a service that will best suit not only your budget but means as well. You should now be a lot more familiar with the various types of machines that this contractor will be utilizing and this should really give you quite a leg up when dealing with said contractor.

General Components of Centrifugal Pumps

September 26th, 2010 Administrator No comments

general-components-of-centrifugal-pumps

Pump is a device which plays a very important role in this society. It has a wide range of applications. It can be divided into various types such as positive displacement pumps, buoyancy pump, impulse pumps, velocity pumps, gravity pumps, and steam pumps.

Among all the above mentioned categories of pumps, the velocity pumps can be future divided into centrifugal pumps, radial flow pumps, axial flow pumps, eductor-jet pumps, and mixed flow pumps. The centrifugal pump is one of the simplest pieces of equipment in any process plant. Its purpose is to convert energy of a prime mover first into velocity or kinetic energy and then into pressure energy of a fluid that is being pumped. The energy changes occur by virtue of two main parts of the pump, the impeller and the volute or diffuser. The impeller is the rotating part that converts driver energy into the kinetic energy. The volute or diffuser is the stationary part that converts the kinetic energy into pressure energy.

There are two main components of the centrifugal pumps. Those are a rotating component and a stationary component. The former consists of an impeller and a shaft, while the latter is composed of a casing, casing cover, and bearings.

Let us first see something about the rotating component. The impeller is the main rotating part that provides the centrifugal acceleration to fluid. It is also classified in many ways. For example, it can be classified according to mechanical construction. There is closed type, open type, semi-open or vortex type if classify according to this. The first type of impellers require wear rings and these wear rings present another maintenance problem. And the open and semi-open impellers are less likely to clog, but they may need manual adjustment to the volute or back-plate to get the proper impeller setting and prevent internal re-circulation.

And another important part of rotating component is the shaft. The basic purpose of it is to transmit the torques encountered when starting and during operation while supporting the impeller and other rotating parts. It must do this job with a deflection less than the minimum clearance between the rotating and stationary parts.

Now, let us get down to some parts of the stationary component. Generally, there are two types of casings which are volute and circular. Volute casings build a higher head, and one of its purposes is to help balance the hydraulic pressure on the shaft of the pump. Circular casings are used for low head and high capacity. Except for them, bearings are also very useful components in the centrifugal pumps.

All these various components are very important. They cooperate well with each other to achieve good performance of centrifugal pumps.

Brief Introduction of the Centrifugal Pump

September 26th, 2010 Administrator No comments

brief-introduction-of-the-centrifugal-pump

A centrifugal pump is one kind of pumps which is quite useful in our daily life. It is a machine for moving a liquid, such as water, by accelerating it radially outward in an impeller to a surrounding volute casing. They are commonly used to move liquids through a piping system.

It can convert the input power to kinetic energy. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump.

Centrifugal pumps will fail despite of all the care in operation and maintenance. That is to say, these pumps can no long be kept in services. Reasons that cause the failure of these products are various. One of the most common conditions is that they are not able to deliver the desired flow and head. There are still many other conditions under which the centrifugal pumps are considered to have failed. For example, there are many problems which are related with seals such as the leakages, loss of flushing, cooling, quenching systems, etc. For another example, there are many other problems that are related with pump and motor bearings such as the loss of lubrication, cooling, contamination of oil, abnormal noise and so on.

When centrifugal pumps fail, it is rather important to find out the root causes of the product failure. Therefore, if centrifugal pumps are not in good status, you should figure out whether the pump has failed mechanically or if there is some process deficiency, or both. There are mainly three types of problems mostly encountered with centrifugal pumps: design errors poor operation poor maintenance practices. Although centrifugal pumps may also fail when you do maintenance, it is also quite necessary for you to do this because proper and careful maintenance can prevent centrifugal pumps from early failure. Also, in case of any mechanical failure or physical damage of pump internals, the operating engineer should be able to relate the failure to the process unit’s operating problems.

All in all, like many other machines, there are many problems which can lead to the failure of the centrifugal pumps. If you want to keep them in good conditions, you should learn things about them comprehensively except for the maintenance.

Chemical Resistant Drum Pump - Putting Reliability and Safety First

August 23rd, 2010 Administrator No comments

chemical-resistant-drum-pump-putting-reliability-and-safety-first2

The numerous ranges of pumps on the market are designed by the manufacturer and purchased by the consumer, for their mechanical performance under specific conditions. When ascertaining the features and quality of a pump, one should consider such aspects as the containment of pressure, fluid sealing, pumping capacity, reliability, ease of use and the range of fluids the pump is capable of handling, including corrosive materials such as chemicals and material that are characterised with high levels of alkalis.

Many pump manufacturers, due to the economic requirement of keeping costs at the lowest levels possible, offer their range of pumps in limited construction types and material composition. However, certain drum pump applications require that the material used is chemical resistant, not only to safeguard the drum and the user of such equipment, but to ensure the fluid does not become contaminated with the inner workings and materials of the drum pump due to corrosive forces. When corrosive materials are in use, the employment of specialised chemical resistant pumps should be considered a must.

Although these pumps are slightly more expensive, when weighing the benefits versus costs model, incorporating the longer life the chemical resistant drum pump will offer; the reliability of such equipment that will ensure that materials are able to be pumped when and where necessary; the reduction of downtime required for the maintenance upon failure, and; the safety guidelines and regulations that must be adhered to - the higher initial cost far outweighs the productive and safety issues that will undoubtedly arise in using a non chemical resistant drum pump.

To ensure that your purchase is going to suit your particular application, it is worthwhile contacting an experienced company who specialises in the production of chemical resistant drum. Specific questions can be answered relating to the composition of the fluid you wish to transfer, the PH levels, temperature of the fluid, the proportion of solids in the fluid and the desired rate of flow. This will ensure that you purchase the correct pump specifically designed for the purposes and applications that you desire.

Leading chemical resistant drum pump manufacturers utilise only the best production methods and resources to construct pumps that demonstrate unsurpassed reliability, quality, longevity, fluid transfer rates and safety features. Search for companies utilising polyethylene and polypropylene in their construction, as these materials prove again and again, their high resistance to chemical corrosion while still creating a drum pump that is rigid and can handle high pressure loads.

Main Applications and Classifications of Pumps

August 23rd, 2010 Administrator No comments

Generally, a pump refers to a machine or device that is used for raising, compressing, or transferring fluids. It is mainly used to transport liquids including water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid metals. Besides, it can also transport gas mixtures and liquids containing suspended solids.

China’s pump industry has a long history of development. It gained rapid development after the reform and opening policy. Apart from a few special pump products, the present categories and quantities can meet the needs of the national industries. There are various types of products such as pumps of rotary displacement,peripheral, reciprocating displacement and vacuum.

Pump products have a wide range of applications. They can be used in many different industries. In the agricultural production, they are the main irrigation and drainage machinery. China has vast rural areas. Those villages need a lot of pumps every year. And agricultural pumps generally account for more than half of the pump output. In the mining and metallurgical industry, they are the mostly used equipments. Water in the mine should be drained by them. They are also used in mineral processing, smelting and rolling process. In the electricity sector, nuclear power plants need nuclear primary pump and many other different kinds of products. And in the national defense construction, these products can be quite useful in the adjustment of the aircraft wing flaps, undercarriage and the stern rudder, rotation of the warships and tanks turret, and submarine’s ups and downs. While in the shipbuilding industry, there are generally more than 100 units of different pumps used in the ocean-going ships. Except for these applications, they can also be applied in urban water supply and drainage, textile industry, and machine tool lubrication and cooling, etc. In short, these products can be seen both in some important industries and our daily life.

Pumps can be classified according to different things. There are positive displacement pumps and impeller pumps if they are classified according to their working principle. As to the latter type, they can be further divided into centrifugal pump, axial pump, mixed-flow pump, peripheral pump, and jet pump. If classify them according to the pump shaft position, there are vertical pump, horizontal pump. There are still many other classification means. All in all, there are so many different pumps that they play rather important role in our industries.
