What is the principle of pneumatic hydraulic pump? How to prove its lifespan?

Pneumatic hydraulic pumps are composed of three main parts: reversing part, driving part, and boosting part. The driving part and the boosting part are connected by a shaft. Practice reciprocating operation of the pump through the reversing section. High pressure output is achieved by the difference in area between the driving piston and the boosting piston. The smoothness and wear resistance of the cylinder barrel and the wear resistance of the sealing ring are related to the overall efficiency and service life of the pneumatic hydraulic pump.

Pneumatic hydraulic pump is a type of plunger pump, which works by relying on the reciprocating motion of the plunger in the cylinder body. Through the check function of the one-way valve, the volume of the sealed working chamber changes to achieve oil suction and pressure. Pneumatic hydraulic pumps have the advantages of high rated pressure, simple operation, compact structure, easy maintenance, and high efficiency. In the process of reciprocating motion, the higher the smoothness of the cylinder body, the smaller the frictional force generated, and the efficiency of the hydraulic pump is greatly improved. The friction is small, and the damage to the steel body is reduced, greatly enhancing the service life of the entire hydraulic pump. So the material of the internal sealing ring is also an important factor related to its lifespan. The material of the cylinder barrel requires smoothness, wear resistance, corrosion resistance, and more importantly, very good hardness. The material of the sealing ring requires wear resistance, high pressure resistance, and high temperature resistance (the reciprocating motion between the cylinder wall and the sealing ring of the pneumatic hydraulic pump during continuous operation will produce a certain degree of stability)

The cylinder barrel of the pneumatic hydraulic pump produced by Taizhou Feentor adopts a material with a hardness of up to HV400. The thin-walled cylinder barrel made of high hardness material replaces the old low hardness thickened cylinder barrel, reducing the weight of the hydraulic pump while strengthening its wear resistance. It won't wear out severely like an old cylinder after less than a thousand presses. Now it is possible to achieve deformation after dozens of compressions. The inner wall surface is treated with special technology, and the smoothness is visible. The roughness of the inner surface can reach Ra0.05. Provides excellent power space for hydraulic pumps. This is the current level of smoothness that can be achieved in the domestic market, comparable to international brands. The sealing ring adopts imported fluororubber and nitrile rubber (MPI) sealing rings to ensure the durability of the product.

Precautions for using pneumatic hydraulic pump

1. Drive the air pressure (3-8 bar) and keep it clean and free of impurities.

2. The pressurized medium (water, hydraulic oil) is clean and free of impurities. If the medium is hydraulic oil, then the viscosity must be considered.

3. Choose the corresponding boost ratio and output flow rate according to your own needs.

4. The on-site usage environment must be kept clean and free from excessive dust.
