How to prevent oil leakage of electric forklift

How to prevent oil leakage of electric forklift

For electric forklifts, oil leakage will inevitably occur when using electric forklifts. How to prevent oil leakage of electric forklifts in practical applications? This is a method to introduce electric forklifts to prevent oil leakage.

1. Handle all kinds of cushions carefully. Such as the oil pan or valve cover, because of the large contact area, it is not easy to compact, and easy to form oil leakage. After the oil seal on the rear of the crankshaft leaks oil, the oil will enter the clutch, which will consume the oil and cause the clutch disc to slip and burn.

2. Tighten the nut according to the maintenance standard. If the compression force is too tight, the gasket will leak; if it is tightened too tight, the metal around the screw hole will protrude, or the thread will slip and cause oil leakage.

3. Replace the failed oil seal in time. Inappropriate oil seal device, the cutting edge of journal and oil seal is different. Because of yaw and oil, it is very simple; long-term use will lose elasticity due to rubber aging, seal lip damage and cracking or spring self-tightening, and lose the oil seal effect. It should be adjusted according to the standard. Qualified parts are corrected or replaced.

4. Timely replace the severely worn parts of the electric forklift. For example, cylinder liners, pistons and piston rings are worn to a certain extent, and the high-pressure gas in the incineration chamber is forced to enter the crankcase.

5. Repair the main bearing in time. When the matching clearance between the main bearing and the journal is too large, the front and rear oil seals will lose their seal due to the impact of the crankshaft, resulting in a state of oil leakage from the crankshaft head or oil leakage to the clutch, and then contaminating the friction plate will cause slippage and operation failure.

The above are several common methods to prevent oil leakage when using electric forklifts. When encountering such problems, people need to solve these problems from the above-mentioned aspects, so that such problems can be effectively suppressed.
