How does the hydraulic system of the electric pallet truck work?

The hydraulic system of the electric pallet truck is an important part of the equipment, and its steering system and working device are driven by the hydraulic system. Therefore, the quality of the hydraulic system will directly affect its performance. In fact, the reasons for the failure of the hydraulic system are not as complicated as we think, and most of the problems are caused by the execution structure. However, it is not easy to find out the specific fault location and cause, because there are many reasons for the fault, and specific problems need to be analyzed in detail.

It is also worth mentioning that the hydraulic transmission failure of the electric pallet truck is very hidden, which also brings a lot of trouble to the maintenance personnel. In the industry, there are many ways to check for faults, and all we care about is the reliability of the diagnostic results. The common fault diagnosis methods of the hydraulic system of the pallet truck are as follows.

The failure rate of the hydraulic system of the electric pallet truck can generally be divided into three stages: the initial stage, the middle stage of operation and the later stage of operation.

In the early stage of the electric pallet truck, when the new equipment or the overhauled equipment system just started to operate normally, the failure rate was relatively high. This is mainly because the level of design of the device may not be perfect. In the selection of components there are still insufficient or the quality is not good enough. If the components and pipelines are not cleaned thoroughly or assembled improperly, there will be failures such as vibration, leakage, unstable system pressure, unstable actuator action, and excessive temperature rise. Don't worry about this situation, as long as the correct solution is taken, the failure rate will be reduced.

The failure rate of electric pallet trucks in the middle of operation is very low, but even if there is a failure, most of the reasons are caused by hydraulic oil pollution or deterioration. Because the dirt in the hydraulic oil will block the throttling hole or throttling gap of the component, thus changing the working performance of the system and causing the component to malfunction.

The electric pallet truck has entered the post-operation overhaul period. The wear of hydraulic components is very serious, and the wear or aging of seals leads to a gradual increase in the failure rate, which is mostly manifested as increased leakage, reduced system efficiency, and slow movement. At this time, it is necessary to contact the electric truck manufacturer in time to solve the problem before the fault does not expand.
