Hydraulic Cylinder Gas in The Reasons And Measures

Hydraulic cylinder gas in the reasons and measures

There may be several reasons for the presence of gas in the hydraulic cylinder:

1, the gas content in the fluid is too high: the gas content in the fluid is too high is one of the main reasons for gas in the cylinder. Common sources of oil gas are oil in the transportation or refueling mixed with a large amount of air, or oil pumped into the tank when the air generated, etc..

2, the hydraulic system temperature is too high: the hydraulic system temperature is too high will make the oil in the gas expansion, easy to form bubbles in the cylinder.

3, poor sealing of the hydraulic system: sealing structure damage or aging and other problems, will make the cylinder internal and external pressure imbalance, resulting in the entry of gas.

For the case of gas in the hydraulic cylinder, the following measures can be taken:

1, exhaust treatment: the problem can be solved by eliminating the gas in the fluid at the right time when the hydraulic system is running. For example, you can set up exhaust valves, air relief ports and other structures in the oil circuit.

2, system oil change: regular replacement of oil in the hydraulic system to avoid excessive air content in the fluid, thereby reducing the possibility of gas entry.

3, overhaul seals: regular inspection of its sealing structure, timely replacement of aging or damaged seals, to protect the sealing performance of the hydraulic cylinder.

4, reduce the temperature of the hydraulic system: can be used to add a radiator, reduce the working pressure of the hydraulic system to reduce the temperature of the hydraulic system, reduce the possibility of gas expansion in the fluid.
