A good partner of hydraulic oil for excavators - hydraulic oil filter

Although the hydraulic oil filter is a small accessory in construction machinery and equipment, it is also lacking. In the hydraulic system, the hydraulic oil filter element is used to filter out solid particles and gelatinous substances in the working medium, prevent the dirt from wearing the equipment, and keep the equipment in good working condition.

In construction machinery, the hydraulic system appears in a variety of equipment, so the status of the hydraulic oil filter is very important.

Moreover, for the full hydraulic excavator, the hydraulic system is distributed throughout the excavator. It includes the hydraulic oil tank, the main pump, the control valve, the various pipelines, and the cylinders and motors that perform the action. These hydraulic components are all Precision machining, they have high requirements for the maintenance of the hydraulic system, so the quality of the hydraulic oil filter is essential.

Some people say that I can buy some poor quality filter cartridges and replace them often? A: No, the quality of the hydraulic oil filter cartridge is critical to the service life of the machine.

Cleaning is a top priority when hydraulic fluid enters the hydraulic system. Poor quality hydraulic oil filter has poor filtering effect and can not effectively prevent dirt and other impurities from entering the system. If the magazine system enters tiny magazine particles, they will scratch the pump, jam the valve, and block the oil port, causing machine failure.

Then how to determine whether the hydraulic components are damaged by periodically checking and replacing the hydraulic oil filter?

Under normal circumstances, the replacement period of the hydraulic oil suction filter is replaced every 2000 hours. The replacement period of the hydraulic return filter is 250 hours for the first time, and then replaced every 500 hours.

When replacing the hydraulic oil filter, check the bottom of the filter for metal particles or debris. If there is copper or iron filings, the hydraulic pump, hydraulic motor or valve may be damaged or damaged. If there is rubber, the hydraulic cylinder seal is indicated. damage. In this way, we can judge where the equipment has been damaged according to the waste.

Hydraulic oil filter has a wide range of applications in life. High-quality hydraulic oil filter can ensure the good operation of the equipment, so we must not ignore the maintenance and replacement of the filter.
