In fact, the pump is a unit that everyone must use in life. Let us look at what it is and how it works in our lives.
Domestic water pumps are equipments that move fluids through their mechanical design. They are used to meet the needs of people's livelihood, such as drawing clean water from a base pool into a water tower on the top floor of a house, or pumping sediment after heavy rain.
What exactly is a pump?
According to the methods of pumps used to move fluids, pumps can be divided into three main types. These three types 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.
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.
The way that pumps installation is also a key. 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.
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.
In fact, whether it is a Domestic water pump, industrial pump or commercial pump, the pump must be equipped with impellers. 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. In the application of biology sector, many different types of chemical and biomechanical pumps have evolved and progressed.
In addition to the impeller numbers, there are two basic types of pumps, that is, positive displacement and centrifugal.
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. Domestic water pumps are actually in many ways just like other pumps.
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.
If possible, users of Domestic water pumps should pay attention to all dangerous factors that may damage the pump body and its mechanism to extend the pumps’ life. In addition, regular maintenance is always a good thing for all mechanical units.
Long story short, even if the structure of the air pump is relatively simple, the supplier's manufacturing process is different. Many of the manufacturing parameters will determine the final quality of the air pump unit.
There are air compressors, bellows, bicycle pumps, diaphragm pumps, engine-driven pumps and many other pumps on the market. On the website, we provide customers with a wide range of options for different types of applications.
