When we use the hydraulic lift, the failure is usually the most hydraulic system failure. How to prevent hydraulic lift hydraulic system fault? Jinan saili machinery to tell you about the relevant matters:
In general, we first from the equipment hydraulic system itself from the point of view of the structure, because the structure is complex and many pipelines, lifting several tens of meters long hose, the manufacturers of the machine operation of the hydraulic lifting mechanism movement, high pressure hose repeated winding movement, prone to fatigue fracture. The load of the equipment varies greatly, and the hydraulic pressure pulsation will occur in the hydraulic system. When the pulsation pharmacology reaches a certain value, the high-pressure rubber hose will be damaged. Secondly, a part of the hydraulic system assembly in the process of movement failure, will cause the system operation failure and forced to stop.
In years of use, we should understand the use of hydraulic lifts and points of failure. According to the above analysis, in the design of the hydraulic elevator hydraulic system targeted put forward some specific technical requirements. In view of the failure of the hydraulic system, because the hydraulic cylinder as the leading lifting driving force, the hydraulic cylinder needs to move with the lifting mechanism, at this time the hydraulic cylinder both as the lifting power and as the construction work of the lift support components. So the hydraulic cylinder and its connected pipeline play a major role in the whole safety system. Therefore, in the design of the hydraulic pipeline as far as possible to use the hard gelatin containing steel mesh tubing, and ensure the tubing requirements, reduce the possibility of failure of the hydraulic system due to system pipeline rupture and leakage.
In addition, when the hydraulic system is normal, the electrical system of the hydraulic system fails (including the control system), causing the system to stop suddenly. In most cases is in the normal work when the sudden power failure of the abnormal shutdown so that the personnel stranded in the upper air can not come down, so in the daily use must follow the manufacturers know, pay attention to maintenance and protection.
