How the secondary vertical injection molding machine handles oil leakage is as follows:
Second-hand vertical injection molding machines found that if there is looseness in the pipe joints or damage to the sealing ring, they should be solved by tightening the joints or replacing the sealing ring; if there is an external leakage at the joint surface of the components, it is mainly due to the insufficient pre-tightening force of the fastening screws and If the seal ring is worn out, it should increase the pre-tightening force or replace the seal ring; if it is found that if the internal pressure of the journal shell is higher than the allowable pressure of the oil seal or the oil seal is damaged, it can be taken out. Reduce the internal pressure of the shell or replace the oil seal to solve; find that if there is an external leakage at the fitting, the pre-tightening force of the V-shaped sealing ring should be adjusted; fifth, the external oil leakage in the oil level gauge of the fuel tank is caused by leakage of water into the oil. Or oil leakage into the water, should be resolved through timely repair.
Therefore, the second-hand vertical injection molding machine reminds us to pay more attention to: check the direction of rotation of the motor oil pump is normal; check whether there is oil leakage; check the pressure flow valve for current; have the hexagon head against the pressure valve is pressed, replace or clean .
