How to clean the burrs in the hydraulic system components
Abnormal noise production, indicating that the parts are damaged or not properly adjusted, should be located in the position of the noise to find out the reason for the prompt maintenance. 1, the hydraulic oil tank, oil pump suction air or oil filter dirt blocking leads to pump oil shortage, lead to bubbles in the oil discharge blade impact and noise, the solution is to check the oil, to prevent the inhalation of air and oil filter cleaning.
The hydraulic component is damaged or the oil pipeline is blocked and the hydraulic oil is running at high speed. 6, mechanical parts failure, bearing wear or mechanical lack of lubricating oil or parts loose, should be found for reasons to tighten or replace parts,
Direction valve failure but function is still in the reaction, such as valve core, internal leakage, burr obstruction, mobile is not flexible, electromagnetic valve failure due to lack of current also can produce noise. The solution is to clean the core of the valve. The valve core frayed must be replaced. The current should be stable and sufficient.
The hydraulic oil viscosity is high, increase the flow resistance, the need to replace the proper hydraulic oil. Due to the failure of the bearing or blade of the oil pump or motor, the concentric deviation of the coupling can cause the noise, and the concentric or replacement parts must be adjusted.
