The hydraulic oil cylinder contains the reasons and measures of gas

The reasons for the presence of gas in the hydraulic cylinder may include the following points:

1. Excessive gas content in the oil: The excessive gas content in the oil is one of the main causes of gas formation in the cylinder. Common sources of gas in the oil include the introduction of a large amount of air during transportation or refueling of the oil, or the air generated when the oil is pumped into the oil tank.

2. High temperature of the hydraulic system: High temperature of the hydraulic system causes the gas in the oil to expand, making it easy to form bubbles in the cylinder.

3. Poor sealing of the hydraulic system: Problems such as damaged or aged sealing structures can cause the internal pressure of the cylinder to be out of balance with the external pressure, leading to the entry of gas.

For the situation where there is gas in the hydraulic cylinder, the following measures can be taken:

1. Gas elimination treatment: This can be achieved by periodically removing the gas from the hydraulic system during operation. For example, structures such as exhaust valves and venting ports can be installed in the oil circuit.

2. System oil replacement: Regularly replace the oil in the hydraulic system to avoid excessive gas content in the oil, thereby reducing the possibility of gas entering.

3. Inspection and replacement of sealing components: Regularly inspect the sealing structure and replace aged or damaged sealing components to ensure the sealing performance of the hydraulic cylinder.

4. Lowering the temperature of the hydraulic system: Measures such as installing a radiator and reducing the working pressure of the hydraulic system can be taken to lower the temperature of the hydraulic system, reducing the possibility of gas expansion in the oil.
