Daily maintenance points for hydraulic systems

(1) Clean the tank with an easy-to-dry cleaning solvent and remove the solvent residue with filtered air.

(2) Clean the entire pipeline of the system. In some cases, the pipeline and joints need to be impregnated.

(3) Install oil filter in the pipeline to protect the oil supply pipeline and pressure pipeline of the valve.

(4) Install a flushing plate on the current collector instead of a precision valve, such as an electro-hydraulic servo valve.

(5) Check that all pipe sizes are appropriate and that the connections are correct.

If the electro-hydraulic servo valve is used in the system, I may wish to say a few more words. The servo valve has to flush the plate so that the oil can flow from the oil supply pipe to the current collector and directly return to the fuel tank, so that the oil can be repeatedly circulated. To flush the system, let the oil filter filter out the solid particles. During the rinsing process, check the oil filter for 1 to 2 hours to prevent the oil filter from being blocked by the pollutants. At this time, the bypass should not be opened. If the oil filter starts to clog. Just change the oil filter.

The cycle of rinsing is determined by the structure of the system and the degree of contamination of the system. If the sample of the filter media has no or very little foreign pollutants, install a new oil filter, remove the rinsing plate, and install the valve!

Planned maintenance: establish a system of regular maintenance system, better maintenance of the hydraulic system, maintenance recommendations are as follows:

(1) Check and replace the oil for up to 500 hours or three months.

(2) Regularly flush the inlet oil filter of the oil pump.

(3) Check that the hydraulic oil is contaminated by acidification or other pollutants. The smell of the hydraulic oil can be roughly identified as to whether it has deteriorated.

(4) Repair the leak in the system.

(5) Ensure that no foreign particles enter the tank from the venting cap of the fuel tank, the plug of the oil filter, the sealing gasket of the return line, and other openings in the tank.
