What does the piston pump do? What are its advantages and disadvantages?
The piston pump is a kind of hydraulic oil pump, which is widely used in hydraulic systems. Its function is to convert the external input mechanical kinetic energy into kinetic energy that increases the pressure by the transmission device, and transfer heat into the hydraulic system in the form of pressure or flow. And it can transport liquid under high pressure. The piston pump has the characteristics of high rated pressure, compact structure, high efficiency and convenient flow adjustment. It is widely used in high pressure, large flow and flow adjustment places, but it also has complex structure, poor self-priming ability, Defects with high requirements for maintenance. Let's take a look at the advantages and disadvantages of piston pump together.
What is the role of the piston pump
The piston pump is an important piece of equipment in the hydraulic system. It is widely used in high-pressure, large-flow, and high-power software where the flow rate must be adjusted. So what is the role of the piston pump?
The function of the piston pump is mainly driven by the transmission device to convert the external input mechanical kinetic energy into kinetic energy that increases the pressure. It can transmit kinetic energy into the hydraulic system in the form of pressure or flow; because the piston pump can also be used in high pressure situations. Therefore, it is widely used in petroleum exploration and development, reaction speed of petrochemical equipment, liquid chromatography analysis, supercritical extraction, separation, nuclear energy science and rationality, environmental ecological engineering, process technology, experimental equipment and a small amount of delivery of various liquids. Liquid and many other aspects.
What are the advantages and disadvantages of the piston pump
As a special centrifugal pump, the piston pump not only has advantages but also defects. Let's take a look at the advantages and disadvantages of the piston pump:
1. Advantages of piston pump
(1) High main parameters: high rated value pressure, high speed, high driving power of the pump.
(2) High efficiency, the volumetric efficiency is about 95%, and the total efficiency is about 90%.
(3) Strong and durable.
(4) The independent variable is convenient and there are many methods.
(5) The output power of the enterprise is relatively light.
(6) The key parts of the piston pump are all subjected to stress, and the strength characteristics of the material can be flexibly used.
2. Defects of piston pump
(1) The structure is more complicated and the number of parts is more.
(2) Poor self-priming ability.
(3) The processing technology is very demanding and expensive.
(4) Hydraulic oil is sensitive to environmental pollution, requires high filtration accuracy, and has high requirements for maintenance.
