How does the hydraulic system of an 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 devices 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 thought, and most of the problems are caused by the execution structure. However, it is not easy to find out the specific fault location and the cause of the fault, because there are many reasons for the fault, and the specific problem needs to be analyzed in detail.
Another point that has to be mentioned is that the hydraulic transmission failure of the electric pallet truck is very concealed, which also brings a lot of trouble to the maintenance personnel. In the industry, there are many ways to check for faults. What we care about is the reliability of the diagnosis results. The common fault diagnosis methods of the forklift hydraulic system are as follows.

The failure rate of the hydraulic system of an electric pallet truck can generally be divided into three stages: initial stage, mid-operation and late-operation.
In the early days of electric pallets, when new equipment or overhauled equipment systems just started to operate normally, the failure rate was relatively high. This is mainly because the design level of the equipment may not be perfect. There are still shortcomings or insufficient quality in the selection of components. If parts and pipelines are not cleaned thoroughly or assembled improperly, failures such as vibration, leakage, unstable system pressure, unstable actuator movement, and excessive temperature rise will occur. Don't worry if you encounter this situation, as long as you take the correct solution, the failure rate will be reduced.

The failure rate of electric pallet trucks in the middle of operation is very low, but even if they fail, most of the reasons are caused by hydraulic oil pollution or deterioration. Because the dirt in the hydraulic oil will block the orifice or throttle gap of the component, which will change the working performance of the system and cause the component to malfunction.
The electric pallet truck has entered the post-operation overhaul period. The hydraulic components are very severely worn, and the seals are worn or aged, resulting in a gradual increase in the failure rate, which is mostly manifested as an increase in external leakage, a decrease in system efficiency, and slow movement. At this time, it is necessary to contact the electric pallet truck manufacturer in time to solve the problem before the problem is not enlarged.
