I. Plunger pumpWhat role does it have
Plunger pump is an important device in the hydraulic system. It is widely used in high-pressure, high-flow, high-power systems and occasions where the flow needs to be adjusted. So what role does the plunger pump play?
The main function of the plunger pump is to convert the mechanical energy input from the outside into the energy that increases the pressure through the drive of the prime mover, and it can transmit the energy to the hydraulic system in the form of pressure or flow; Plug pumps can transport liquids under high pressure, so they are widely used in petroleum exploration and development, petrochemical catalytic reactions, liquid chromatography analysis, supercritical extraction, separation, atomic energy science, environmental science, process equipment, experimental equipment and various Liquid micro-feeding and so on.
Second, the advantages and disadvantages of plunger pump
Plunger pump as a special water pump , it has both advantages and disadvantages, the following will introduce the advantages and disadvantages of the plunger pump:
1. Advantages of the plunger pump
(1 ) High parameters: high rated pressure, high speed, and high driving power of the pump.
(2) High efficiency, the volume efficiency is about 95%, and the total efficiency is about 90%.
(3) Long service life.
(4) Variables are convenient and have many forms.
(5) Light weight per unit of power.
(6) The main parts of the plunger pump are all subject to compressive stress, and the strength and performance of the material can be fully utilized.
2. Disadvantages of plunger pump
(1) The structure is more complex and the number of parts is large.
(2) Poor self-priming.
(3) The manufacturing process requirements are higher and the cost is higher.
(4) Oil is more sensitive to pollution, requires higher filtration precision, and has higher requirements for use and maintenance.
Three, Plunger pumpFor what occasions
Because the plunger pump has a rated It has the advantages of high pressure, compact structure, high efficiency and convenient flow adjustment, so it is widely used in occasions where high pressure, large flow and flow need to be adjusted, such as hydraulic presses, construction machinery and ships.
