Commercial Water Pump

Commercial water pumps have a wide range of applications, such as pumping water from wells, aquarium filtration work, pond filtration tasks, water cooling and fuel injection in the automotive industry, oil and gas pumping or operating cooling towers in the energy industry, and so on.

In the field of machine tools, pumps are used to transfer cutting fluids, coolants, etc. Therefore, when a manufacturer produces a machine tool, the pump is considered to be an essential component of the machine tool, not an optional component.
The density of coolant and cutting fluid is a key element in the selection of pumps. Users must understand these combinations and make the right choices accordingly.

 
Types of Components and Parts

Characteristics of Commercial water pumps

Commercial water pumps are devices that move liquids through their mechanical design and are used in commercial applications.
 
According to the methods of pumps used to move fluids, pumps can be divided into three main models. These three models are determined by the way they move fluids, and there are direct lift, displacement, and gravity methods. That is, there are direct lift pumps, displacement pumps, and gravity pump respectively.

Commercial water pumps are typically operated by either reciprocating or rotary mechanisms, and consume energy to perform mechanical work that moves the fluid, thereby improving liquid delivery performance.
 
Commercial water pumps can also be classified by their discharge way into positive displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps, and valve-less pumps. Besides, there are two basic types of pumps, that is, positive displacement and centrifugal.

 
Other pumps

Based on the above introduction, the positive displacement pump makes a certain amount of liquid flow into the discharge pipe, so that the fluid moves.
 
Usually displacement pumps use expanding cavity on the suction side and then use decreasing cavity on the discharge side. With this method, when the cavity on the suction side expands, liquid flows into the pump, and when the cavity squeezes, the liquid flows out from the discharge side. In each operation cycle, the amount of liquid is constant.
 
The positive displacement pump can produce the same flow rate at a given speed, regardless of the discharge pressure, that is, the positive displacement pump is a constant flow mechanism. However, as the pressure increases, the internal leakage will increase slightly, thus preventing a truly constant flow.
 
Since the positive displacement pump does not have a shutoff head like a centrifugal pump, the positive displacement pump cannot work against the closed valve on the discharge side of the pump. The positive displacement pump continues to operate to generate flow, but the pressure in the discharge pipe continues to increase until the pipe bursts, severely damaging the pump.
 
For safety reasons, pump manufacturers will install a safety valve on the discharge side of the positive displacement pump. This valve can be installed either internal or external.

 
Power supply of pumps

Pumps can be operated by many power sources, such as manual operation by field operators, or by electricity or engines, and even by sustainable energy sources such as wind energy.
These energy sources can be used in a variety of equipment, ranging in size from a micro microscope for medical use to large industrial pumps in waterworks, or small industrial pumps that transfer coolant from machine tools to cutting fluids.  

 
Impellers

In addition, the number of impellers determines the working mode of the pump and the liquid intensity. If for example, there is a pump that contains only one revolving impeller, it is called a single-stage pump. If a pump contains two or more revolving impellers, it is called a double- or multi-stage pump.

 
Conclusion

Although the structure of the pump is simpler and easier to build than other mechanical parts in the machine tool field, the real difference in pump production technology lies in accuracy, durability and user-friendly maintenance design to ensure the output quality and operation of the pump.
 
It is foreseeable that as the technology continues to advance, these three key points will become more and more mature in the industry, resulting in better and more advanced pump technology.
