Electric stacker is a kind of storage equipment with battery power as the energy source and motor as the power source. It is composed of battery, motor, hydraulic pump, oil cylinder, piston and other components. Among them, the oil cylinder is the part that converts hydraulic energy into mechanical energy, which is very important for the electric stacker. However, oil leakage is a common problem of electric stacker, which gives many drivers a headache. In case of oil leakage from the electric stacker, don't worry. The electric stacker manufacturer will explain how the electric stacker leaks oil and how to solve it.

The oil leakage of the electric stacker may be due to the wear between the valve stem and the valve body. If the distribution valve is frequently used with high intensity or the oil is not clean, the wear between the valve stem and the valve body will be increased. This may damage the mating sealing surface and cause oil leakage. If the wear is not too serious, the chrome plating of the valve stem can be polished to prevent oil leakage. If the wear is serious, the parts need to be replaced in time. The oil leakage of the electric stacker may also be due to the poor sealing of the connection between the oil pipe and the oil cylinder or the pump station. At this time, use a wrench to tighten the nut at the connection. The electric stacker manufacturer reminds that in order to prevent wire slipping, it is not allowed to use too much force.
If the electric stacker leaks oil, it may be that the spring of the safety valve is aging, causing the hydraulic oil to force the steel ball to leave the valve position and flow into the oil spillway under the pressure lower than that specified by the system, resulting in oil leakage. To solve this problem, replace the spring, and then adjust the spring pressure to the specified 14 MPA with screws. If the stem of the multi-way directional valve cannot be reset, the groove is connected with the oil passage, which may also cause oil leakage. There may be two reasons for this problem. One is that the return spring of the valve stem is deformed or damaged, and only the spring needs to be replaced. Second, due to the uncleanness between the valve body and the valve stem, the resistance increases and the valve stem is difficult to reset. The electric stacker manufacturer recommends cleaning the multi-way reversing valve to keep its interior clean and tidy.

Oil leakage of electric stacker is not uncommon. Once it occurs, it may delay normal operation and affect work efficiency. In case of such a problem, the driver needs to calm down, investigate in time, find the reason and solve the problem. The electric stacker manufacturer recommends that the driver increase the knowledge reserve of the electric stacker to facilitate rapid repair.
