Pumps

In the department of chemical and oil production, raw materials, semi-finished products and finished products are liquid, and the raw material, semi-finished products and finished products need to go through complex processes, pumping play in these processes for conveying liquid and provide the role of the pressure of the chemical reaction flow, in addition, also used in many gear pump to adjust temperature.
In agricultural production, pump is the main irrigation and drainage machinery.
Our country countryside is vast, every year the countryside needs a large number of diaphragm pump, generally speaking, agricultural pump accounted for more than half of the pump output.
Pumps are also the most commonly used equipment in the mining and metallurgical industries.
A mine needs to be pumped for drainage, and for water supply during mineral processing, smelting and rolling.
In the power sector, nuclear power plants need nuclear main pump, secondary pump, tertiary pump, thermal power plants need a large number of boiler feed water pump, condensing water pump, oil and gas mixed transport pump, circulating water pump and ash pump.
In the construction of national defense, the adjustment of aircraft flaps, rudder and landing gear, the rotation of warships and tank turrets, the ups and downs of submarines and so on all need to use pumps.
High pressure and radioactive liquid, some also require pump without any leakage, etc.
In short, whether it is aircraft, rockets, tanks, submarines, drilling, mining, trains, ships, or daily life, pumps are needed everywhere, and pumps are in operation everywhere.
Exactly so, so the pump as a general machinery, it is a major product in the mechanical industry.
Electric pump, that is, electrically driven pump.
Electric pump is composed of pump body, water pipe, pump base, submersible motor (including cable) and starting protection device.
Pump body is the working part of submersible pump, it is composed of inlet pipe, diversion housing, check valve, pump shaft and impeller and other parts.
The impeller is fixed on the shaft in two ways.

Positive displacement pump
By the movement of the working part, the working volume increases and decreases periodically, and the liquid is sucked and drained, and by the extrusion of the working part, the pressure of the liquid can increase directly.
According to the motion of the different parts of the movement is divided into: reciprocating pump and rotary pump two types.
According to the different structure of moving parts: piston pump and plunger pump, gear bitumen pump, screw pump, vane pump and water ring pump.
