Dredging hydraulic system should be how to maintain, here to introduce the hydraulic system maintenance Instructions:
1, dredge hydraulic system before the operation of carefully check whether the system leaks oil, the connection is loose, piston rod and hydraulic hose is not a collision, hydraulic pump in the low-pressure oil when the connection is not a solid reliable, oil tank is not the correct standard, all the main power mechanism solenoid valve is not in the most original state, to ensure that the hydraulic system and mechanical equipment in good condition. Atmospheric pressure tank also need to check and clean the gas tank vent, keep it unblocked, can prevent the blockage of the gas tank caused by the vacuum phenomenon, resulting in hydraulic oil pump oil difficulties and damage, etc.
2, dredge hydraulic system operation of the circuit inspection regularly check the pipeline and components between the street and sealing device failure of the sealing device should be replaced in a timely manner, the fittings and all kinds of bolts need to tighten. Through watching, smelling, listening, touching and other methods, and often check the system and the operation of various equipment, noise, pressure fluctuations, leakage, vibration and other anomalies, should immediately analyze the cause and timely treatment to eliminate the hidden dangers.
3, especially to pay attention to the hydraulic pump and overflow valve sound, if it is a hydraulic pump cavitation noise, after the exhaust can not be eliminated after the cause should be identified after troubleshooting can be used. If the execution of components in the absence of load slow movement, and accompanied by overflow valve overflow sound, should be immediately shut down and overhaul.
4. The Daily maintenance and maintenance of hydraulic system of dredger is in strict accordance with the requirements of equipment maintenance manual, timely replacement of perishable oil-resistant rubber bands, filter elements, etc., to reduce the leakage of pipelines to prevent loss of pressure; regular movement of the actuator parts to prevent rust to reduce operating resistance; regular use of the same brand of hydraulic oil to the pipeline, fuel tank, filter, etc. to clean.
