3 Simple Steps To Relieve Pressure in Hydraulic Tube

During the operation of the hydraulic system, hydraulic tubes pressure relief is an important step, which can effectively protect the hydraulic system and related equipment and avoid safety problems caused by excessive pressure. Below, we will introduce the three simplest steps for hydraulic tube pressure relief to help you better perform pressure relief work.

3-step method for hydraulic tube pressure relief operation

1. Turn off the hydraulic pump and cut off the power supply

Before performing hydraulic tube pressure relief, you must first turn off the hydraulic pump and cut off the power supply to ensure the safety of the pressure relief process. This step is crucial because pressure relief while the hydraulic pump is running may cause danger.

After turning off the hydraulic pump and cutting off the power supply, you should wait for a while for the pressure in the hydraulic system to gradually stabilize. During this process, you can observe the reading of the hydraulic gauge to determine whether the pressure in the system has been reduced to a safe range.

2. Use a manual pressure relief valve for pressure relief

When the pressure of the hydraulic system is stable and reduced to a certain extent, a manual pressure relief valve can be used for pressure relief. The manual pressure relief valve is usually located on the main pipeline of the hydraulic system, and the pressure of the system is adjusted by rotating the valve handle.

When operating the manual pressure relief valve, the valve handle should be rotated slowly to avoid damage to the system due to excessive pressure changes. At the same time, the reading of the hydraulic gauge should be closely observed to ensure that the pressure is reduced steadily. When the pressure drops to the appropriate range, the valve handle can be stopped to complete the pressure relief operation.

3. Check the status of the hydraulic tube and hydraulic system

After the pressure relief is completed, the hydraulic tube and hydraulic system need to be fully inspected to ensure that there is no leakage, damage or other abnormal conditions. If any problems are found, valve, pipe flange and other related components should be repaired or replaced in time to ensure the normal operation and safety of the hydraulic system.

In addition, the pressure relief valve needs to be inspected and maintained regularly to ensure its normal operation. If the pressure relief valve is found to be faulty or leaking, it should be repaired or replaced immediately to avoid unnecessary damage to the hydraulic system.

Key considerations

1. Environmental protection

Place an oil pan under the valve before pressure relief to avoid oil pollution; if it is flammable hydraulic oil, keep away from open flames.

2. Emergency preparation

Equip the work area with fire extinguishers and make clear evacuation signals when multiple people collaborate.

3. Tool selection

Use anti-static tools (flammable environment), and do not use alternative tools (such as wrenches instead of special valve stems).

Summary

In short, the pressure relief operation of hydraulic tubes needs to strictly follow safety regulations and operating procedures to ensure the safety and effectiveness of the operation process. Through this article's introduction to the three simplest steps of hydraulic tube pressure relief, I believe you have a deeper understanding of the operation of hydraulic tube pressure relief. When performing actual operations, please pay attention to safety and follow relevant operating specifications.
