The Motor Pumps is a pump driven by electricity. The electric pump is composed of a pump body, a pumping pipe, a pump seat, a submersible motor, and a starting protection device. The pump body is the working part of the submersible pump. It is composed of a water inlet pipe, diversion shell, check valve, pump shaft, and impeller. There are two ways to fix the impeller on the shaft.

In the production of the chemical and petroleum sectors, most of the raw materials, semi-finished products, and finished products are liquids, and the production of raw materials into semi-finished and finished products requires complicated technological processes. In these processes, electric pumps play the pressure to transport liquids and provide chemical reactions. In addition, in many devices, electric pumps are used to adjust temperature; in agricultural production, electric pumps are the main drainage and irrigation machinery. my country's rural areas are vast, and a large number of pumps are needed every year in rural areas. Generally speaking, agricultural pumps account for more than half of the total pump output; in the mining and metallurgical industries, electric pumps are also the most used equipment. Mines need to use pumps to drain water. In the process of beneficiation, smelting, and rolling, pumps are needed to supply water, etc.; in the power sector, nuclear power plants need nuclear main pumps, secondary pumps, tertiary pumps, thermal power plants require a large number of boiler feed pumps, and condensation Water pumps, oil-gas mixed pumps, circulating water pumps, ash, and slag pumps, etc. In short, whether it is airplanes, rockets, tanks, submarines, or drilling, mining, trains, ships, or daily life, electric pumps are needed everywhere, and pumps are running everywhere. Because of this, the pump is classified as general-purpose machinery, which is a major product in the machinery industry.

Electric Plunger Pumps can be divided into three categories: axial plunger pumps, radial plunger pumps, and in-line plunger pumps. The plungers in the axial plunger pump are arranged axially. When the axis of the cylinder block and the axis of the drive shaft coincide, it is called a swashplate type axial piston gear pump; when the axis of the cylinder block and the axis of the drive shaft are not on a straight line and form an angle, it is called a slanted shaft axis. Plunger pump Axial plunger pump has the advantages of compact structure, high working pressure, and easy realization of variables. The characteristics of the axial piston pump: Because the arrangement of the plungers can make full use of the space position for three-dimensional arrangement, the radial size is reduced, so the volume is small; it is used in the question of the sliding shoe and the swashplate, the cylinder block, and the oil distribution plate. The principle of hydrostatic bearing, so the axial piston pump can continue to work at higher speed and higher pressure, it is very easy to realize the variable, and the variable form is various, and it can even combine a variety of input methods and multiple functions because of the oblique The disc structure can realize through-shaft drive, and the inclination angle of the swash plate is generally about 20". The space required for the pump from the forward displacement to the reverse displacement is small, so it is widely used in variable pumps and those that need to be driven. It is used in plunger pumps. The inclined shaft structure cannot achieve through-shaft drive, and the angle between the plunger and the drive shaft is 200 to 450, and the space required for the pump from the forward displacement to the reverse maximum displacement is relatively short. Large. Therefore, it is generally used for quantitative pumps, and this structure is more used for the structure of plunger motors.
