How to deal with oil leakage of walking forklift?

Walking forklift is a kind of logistics storage equipment with battery as power source, which is composed of battery, motor, hydraulic pump, oil cylinder, piston and other components. Among them, the role of oil cylinder is very important, which can convert hydraulic energy into mechanical energy. However, although the walking forklift is easy to maintain and durable, oil leakage is unavoidable. Don't worry about oil leakage of walking forklift. The electric forklift manufacturer will tell you how to find out the cause of oil leakage of walking forklift and deal with it correctly.

One of the reasons for the oil leakage of the walking forklift may be the wear between the valve stem and the valve body. If the distribution valve is often used with high intensity or the oil is not clean, the wear between the valve stem and valve body will be increased, the matching sealing surface will be damaged, and oil leakage will occur. To solve this problem, we must first solve the problem of wear. If the wear is not too serious, the valve rod chrome plating can be polished. If the wear is too serious, it needs to be replaced in time to avoid oil leakage. The oil leakage of the walking forklift may also be due to the poor sealing of the connection between the oil pipe and the oil cylinder or the pump station. In this case, use a wrench to tighten the nut at the connection. The electric forklift manufacturer reminds everyone that you should not tighten the nuts too hard, or the problem of thread slipping may occur.

The aging of the safety valve spring is also the cause of oil leakage of the walking forklift. The hydraulic oil will force the steel ball to leave the valve position and flow into the overflow passage when the pressure is lower than the specified pressure of the system, resulting in oil leakage. To solve this problem, it is necessary to replace the spring first, and then use the screw to adjust the spring pressure to the specified 14 Mpa. The valve rod of the multi way directional valve cannot be reset, and the groove is connected with the oil passage, which may also lead to oil leakage. This is caused by two reasons. First, the return spring of the valve stem is deformed or damaged. At this time, it is only necessary to replace the spring. Second, the valve body and the valve stem are contaminated with dirt, the resistance increases, and the valve stem is difficult to reset. The electric forklift manufacturer recommends that everyone clean the multi way directional valve to keep its interior clean and tidy.

Oil leakage of walking forklift is very common, which greatly affects the working efficiency. Don't worry and worry when encountering this kind of problem. It is most important to find out the cause in time and suit the remedy to the case. The electric forklift manufacturer suggests that the driver should accumulate more experience in practice so as to deal with various sudden failures more easily.
