Fault Analysis of Hydraulic System of Hydraulic Boarding Bridge

The hydraulic boarding bridge is an auxiliary tool for cargo loading and unloading. With it, the forklift truck can easily enter the inside of the car or the container for bulk loading and unloading operations. The hydraulic boarding bridge greatly improves the loading and unloading efficiency, which is indispensable for logistics enterprises. tool. Learning to correctly analyze the cause of the hydraulic system of the hydraulic boarding bridge will help us properly maintain and use the hydraulic boarding bridge.
With the development of society, hydraulic boarding bridges are increasingly used in various enterprises. Therefore, it is very important to ensure the normal operation of the hydraulic system and increase the reliability of the work. The correct selection of the type and viscosity of the hydraulic oil is the primary condition for ensuring long-term and reliable operation of the system. On the other hand, it is also important to be able to quickly find the cause and effective solution when the hydraulic system fails. Hydraulic equipment is composed of mechanical, hydraulic, electrical and instrumentation devices. Therefore, in the analysis of hydraulic system failures, it is necessary to understand the transmission principle, structural characteristics, components and material configuration of the entire hydraulic system. Since the hydraulic system is a sealed pressure system, the flow of oil in the pipeline, the movement of the internal components of the hydraulic component and the damage of the seal are not easily observed, so it is difficult to analyze the cause of the fault and determine the fault location.

There are many reasons for the failure of the hydraulic boarding bridge http://hydraulic system. There are three aspects in summary:
First, the mechanical failure of the equipment, including the unreasonable design of the hydraulic system, incorrect installation clearance, quality problems of hydraulic components, improper selection of seals, etc., hydraulic system failure caused by these problems is generally not related to hydraulic oil.
The second is the failure of the hydraulic system caused by the operation error. This means that the hydraulic system is caused by improper operation of the operator during normal operation. For example, if the valve is opened or closed incorrectly, the power supply is suddenly interrupted, the operating temperature or pressure is too high, and the wrong oil is added during refueling. The oil level of the fuel tank is too high or too low, and the separated water is not released from the bottom of the fuel tank in time. Hydraulic system failures caused by operational errors are not caused by hydraulic oil quality problems, and most do not involve hydraulic oil, but some can be reflected from the quality changes of hydraulic oil.
Third, the hydraulic system is faulty due to the quality of the hydraulic oil. This is mostly caused by improper oil selection or the use of unqualified oil. It may also be caused by excessive use of hydraulic oil and failure to replace new oil in time.
Because the hydraulic boarding bridge is frequently used, it is also a common phenomenon to malfunction. The reasons for the failure of the boarding bridge are as follows:

1. The equipment failure of the hydraulic boarding bridge itself mainly includes the unreasonable design of the boarding bridge and the irregular installation.
2. Improper operation of the boarding bridge will directly cause certain damage to the hydraulic system. During the use process, the power supply cannot be suddenly cut off. If the operating pressure and temperature are too high, the hydraulic boarding bridge will cause internal injuries and increase the difficulty of maintenance. . The inside of the tank of the boarding bridge should be kept clean and the amount of oil should not be too much.
3, the quality of the oil used in the axle, if the use of substandard hydraulic oil will cause the fuel tank can not be used normally, in addition, the oil inside the fuel tank can not be stored for too long, if you do not have to clean it regularly.
