How to remove air from the hydraulic system of an electric forklift?

When maintaining the hydraulic system of an electric forklift, replacing hydraulic components, or changing oil, air entering the hydraulic system must be promptly eliminated. Regardless of the brand of forklift for sale, air entering the hydraulic system of the forklift can cause many failures, such as cavitation and cavitation, making the hydraulic components unstable in operation, generating noise, and so on. Serious impact on work progress. Next, the electric forklift manufacturer will tell you how to remove air from the hydraulic system of electric forklift, and how to prevent this situation from occurring.

The electric forklift manufacturer tells everyone that in general, when the electric forklift is empty, they can repeatedly lift, lower, tilt forward, and tilt back, allowing the air in the system to drain back to the fuel tank. However, it is important to add sufficient oil in a timely manner to keep the oil level at least below the indicated line of the oil pointer. When the lifting cylinder adopts a plunger cylinder, the vent plug can be unscrewed while the plunger rises to vent. When a piston cylinder is used for the lifting oil cylinder, the inlet pipe joint can be loosened for exhaust when the piston drops to the lowest point with no load. Regardless of the brand of the forklift for sale, immediately tighten the screw plug or inlet pipe joint after eliminating the occurrence of oil without bubbles.

How to prevent air from entering the hydraulic system of electric forklift? During the use and maintenance of electric forklift, we should pay attention to the following points. First, it is necessary to frequently check the height of the hydraulic oil level so that it can always be maintained on the oil scale line. Under various operating conditions, make the pump suction port always below the liquid level. Secondly, the pressure in the hydraulic system should be prevented as much as possible from being lower than the atmospheric pressure. At the same time, good sealing devices should be used, and if they fail, they should be replaced in a timely manner. The nuts at the oil pipe joints and each joint surface should be tightened, and the filter at the pump inlet should be cleaned in a timely manner. Third, for the oil cylinder equipped with an exhaust valve, it should be timely opened for venting according to the situation, but it should be tightened after venting. Fourth, regardless of the brand of the forklift for sale, when possible, antifoaming agents can be added to the oil or defoaming nets can be installed in the oil tank to facilitate the suspension and breaking of bubbles in the oil.

The above is the method of exhausting air from the hydraulic system of electric forklift, as well as the preventive measures we can take. The manufacturer of electric forklifts tells everyone that no matter what the brand of forklift for sale, there should be no hurry when the hydraulic system enters the air. Follow the methods taught by the electric forklift manufacturer to quickly solve the problem.
