Before a system is put into general to go through the washing, the washing purpose is to remove residual contaminants in the system, scrap metal, fiber core compounds, etc., in the first two hours of work, even if not completely damage the system will cause a series of failures. Therefore, the following steps should be used to clean the system circuit:
(1) clean the tank with a dry cleaning solvent, and then purge the solvent residue with filtered air.
(2) clean all the piping of the system; in some cases, the pipes and joints need to be impregnated.
(3) installed in the pipe oil filter to supply line and pressure line protection valve.
(4) a flush plate is installed on the flow collector to replace the precision valve, such as electrohydraulic servo valve.
(5) check all piping sizes and make sure the connections are correct.
If the use of electro-hydraulic servo valve system, I wish to say a few words, the servo valve to flush the plate to make the oil from the oil pipeline to the collector, and return the tank, allowing the oil circulation to flushing the system repeatedly, let the oil filter out solid particles, washing process, not every 1 to 2 hours to check the oil filter, oil filter to prevent pollutants is blocked, this time not to open the bypass, if found oil filter immediately began to block oil filter.
The cycle of washing is determined by the system's structure and the extent of the system contamination. If the filter medium has no or very little foreign contaminants, it is equipped with a new oil filter to remove the wash plate and fit the valve!
Planned maintenance: establishment of regular maintenance system, good maintenance for hydraulic system, and suggestions for maintenance:
(1) check and replace the oil at most 500 hours or three months.
(2) regularly flush the inlet oil filter of the oil pump.
(3) check the hydraulic oil is acidified or other pollutants pollution, the smell of hydraulic oil can roughly identify whether the deterioration.
(4) repair the leak in the system.
(5) make sure that no foreign particles come into the tank from the breather cap, the oil filter plug seat, the gasket seal of the return line, and the other openings in the tank. |
