The unloading of hydraulic system should follow these 3 steps

Usually, after the hydraulic system is used for a period of time, it is necessary to relieve the pressure, so that the hydraulic system can get a period of rest. Today, Dalan hydraulic Xiaobian will teach you to do a good job under the unloading of the hydraulic system.

(1) To cut off the power or power source

The most important step in hydraulic system pressure relief is to first cut off the power or power source, so that the hydraulic device stops all operation. When the system is all stationary, you can do some preliminary work of pressure relief, such as before removing the hydraulic cylinder, the hydraulic circuit should be relieved.

(2) Disassemble in order

When the hydraulic system is completely static, after the early work is done, it can be disassembled to achieve the purpose of pressure relief. When disassembling the hydraulic system, be sure to proceed in order. However, because the structure and size of the hydraulic system are not the same, the order is slightly different. Of course, in the entire process of disassembly, conditions must be created to prevent the parts of the hydraulic system from being contaminated by surrounding dust and impurities.

(3) Check and install

When all hydraulic components are removed, do a careful inspection to determine which parts can continue to be used, which parts can still be used after maintenance, which parts need to be replaced immediately, and so on. After making sure that they are correct, each part that can be used is carefully cleaned. Can be assembled in a specific order. After the assembly is completed, it can not be put into use immediately, but should be repeatedly reciprocated under low pressure to remove the gas in the cylinder.
