A hydraulic system is typically flushed before it is officially placed. The purpose of the flushing is to remove contaminants, metal chips, fiber compounds, iron cores, etc. that remain in the system.
A hydraulic system is typically flushed before it is officially placed. The purpose of the flushing is to remove contaminants, metal chips, fiber compounds, iron cores, etc. that remain in the system. In the first two hours of work, even if the system is not completely damaged, it will cause a series of failures. Therefore, the Dalan hydraulic system reminds you that you should clean the hydraulic system oil circuit by the following steps:
1. Clean the tank with an easy-to-dry cleaning solvent and remove the solvent residue with filtered air.
2. Clean all piping in the system. In some cases, the piping 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 hydraulic system, the flushing plate of the servo valve should allow the oil to flow from the oil supply line to the current collector and directly return to the oil tank, so that the oil can be repeatedly circulated to flush the system. The oil filter filters out the solid particles. During the rinsing process, check the oil filter every 1~2 hours to prevent the oil filter from being blocked by the pollutants. At this time, the bypass should not be opened. If it is found that the oil filter starts to block, immediately 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 contaminants, install a new oil filter, remove the rinsing plate, and install the valve.
Establish a system regular maintenance system and have good maintenance on the hydraulic system. The 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 discriminated.
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.
