The rubber compression molding machine is powered by a hydraulic pump, the operation of the oil cylinder is controlled by the solenoid valve and sensors, and all the machine operating procedures are set by the touchscreen&button switch. The quality of the machine determines the cleanliness of the machine and the image of the company. Poor curing opportunities often cause oil leakage, affecting the appearance of the workshop, and causing inconvenience to production and operation. The following analyzes and lists solutions to common oil cylinder problems.
1. Oil leakage from the main cylinder seal
Cause analysis: U- seal are aging for a long time, do not adjust piston
Solution: Change the U- seal, re-adjust the piston connection
2. Broken oil pipe
Cause analysis: There is friction between the oil pipe and the moving parts, or the length of the oil pipe is not enough
Solution: Change oil hose, use suitable length of oil hose
3. Oil leakage of slide in&out cylinder
Cause analysis: There are impurities falling into the cylinder, connection between cylinder&plate not in a line
Solution: Change U- seal and dust seal; slide in&out cylinder joint adjustment
4.Oil leak of vacuum cover cylinder
Cause analysis: Vacuum casting deform, no guide structure
Solution: Add guide structure, change U- seal
5. Oil leak of auxiliary cylinder
Cause analysis: Aging U seal
Solution: Change U-seal and dust seal
6. Oil leak of molding open structure cylinder
Cause analysis: The force is too heary of molding open structure, the U-seal is aging
Solution: Improve mold structure, reduce force, change U-seal.
