Working process of small electric forklift hydraulic transmission system

 

The hydraulic system of a small electric forklift is an important part of the equipment, and its steering system and working devices are all driven by the hydraulic system. Therefore, the quality of the hydraulic system of the equipment will directly affect its performance. In fact, the reason for the failure of the hydraulic system is 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 it is necessary to analyze the specific problems according to forklift manufacturers in china.

And one more thing I have to mention is that the small electric forklift hydraulic transmission failure has a great concealment, which also brings a lot of trouble to the maintenance personnel. In the industry, there are many ways to check for faults. Forklift manufacturers in china only care about the reliability of the diagnosis results. The fault diagnosis method of the common forklift hydraulic system is as follows.

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

In the initial stage of small electric forklift, when a new equipment or equipment system that has undergone an overhaul has just begun to operate normally, the failure rate is relatively high. Forklift manufacturers in china indicate that this is mainly because the design level of the equipment may not be perfect. In terms of the selection of components, there are still lacking or the quality is not good enough. If components and pipelines are not thoroughly cleaned or assembled improperly, there will be failure phenomena such as vibration, leakage, unstable system pressure, unstable movement of actuators, and excessive temperature rise. Don't worry if you encounter this situation, as long as you take a proper solution, the failure rate will decrease.

The failure rate of the small electric forklift in the middle stage of operation is very low, but even if it fails, most of the reasons are caused by the contamination or deterioration of the hydraulic oil. Because the dirt in the hydraulic oil will block the orifice or throttle gap of the component, this will change the working performance of the system and cause the component to malfunction or malfunction.

The small electric forklift is approaching the overhaul period in its later stages of operation. Forklift manufacturers in China suggest that if the hydraulic components are very worn and the seals are worn or aging, the failure rate will gradually increase, which is mostly manifested by problems such as increased external leakage, decreased system efficiency, and slow motion.
