The hydraulic system of the 12 volt hydraulic power unit is its core part, and requires regular repair and maintenance to ensure its normal operation and extend its service life. The following are common maintenance methods for hydraulic systems:
12 volt hydraulic power unit hydraulic system common maintenance methods
1、 leak point repair:
Leak points in hydraulic systems are one of the most common failures.
When you find a leak, first check the location of the leak point. Then, replace the damaged seal or repair the sealing surface. At the same time, you should also check whether the pipeline connections are firm. If they are loose, tighten them.
2、 hydraulic pump maintenance:
Hydraulic pump is the power source of the hydraulic system, if the hydraulic pump fails, the hydraulic system will not work properly.
When the hydraulic pump has no pressure or runs abnormally, you can check whether the pump inlet is blocked, clean the inlet;
Check if the pump suction filter is clean. If dirt is present, clean or replace the filter;
Check if the pump seals are worn or aging. Replace them if needed.
3、 hydraulic valve maintenance:
Hydraulic valves play a role in controlling the flow and pressure in the hydraulic system, if the hydraulic valve fails, it will lead to the system can not work normally.
When the hydraulic valve gets stuck or leaks oil, check if the spool is stuck first. Clean the spool and valve body.
Check whether there are impurities or deposits in the valve body, if necessary, clean the valve body;
If you find damage to the spool or valve body, you need to replace them with new ones.
4、 hydraulic cylinder maintenance:
Hydraulic cylinder is an executive element in the hydraulic system, if the hydraulic cylinder can not work properly, it will affect the action of the system.
When the hydraulic cylinder has no action or exhibits unstable action, check the internal seals for damage and replace them if necessary.
Check whether the hydraulic cylinder oil inlet blocks, and clean it;
Check if someone has jammed the piston of the hydraulic cylinder, and repair or replace it if necessary.
5、 the maintenance of the oil circuit:
Clogging, dirt and other problems may occur in the oil circuit of the hydraulic system, affecting the normal operation of the system.
Regularly clean and inspect the oil circuit to remove dirt and impurities; replace the cartridge and filter in the oil circuit to ensure that the oil is clean;
Maintain the proper temperature of the fluid to avoid overheating or overcooling.
In addition to the above maintenance methods, it is also necessary to pay attention to the regular replacement of the fluid in the hydraulic system to maintain its normal lubrication and cooling performance. In addition, maintenance personnel should regularly check the pressure and temperature of the hydraulic system. They should also record these measurements to find and solve problems in a timely manner.
In short, maintaining the hydraulic system requires maintenance personnel to have certain professional knowledge and skills. It also requires regular maintenance to ensure the normal operation and safety of the hydraulic station.
