    我们在使用液压升降机的时候,故障出现最多的通常是液压系统的故障。如何防范液压升降机的液压系统故障?济南赛力机械为您讲述相关事宜:

    一般情况下,我们首先从设备液压系统本身的结构来看,由于结构复杂和管路众多,起重有数根长达几十米的软管,厂家的机器作业时液压升降机构运动,高压胶管反复进行绕曲运动,容易产生疲劳断裂。设备的负载变化较大,液压系统内将产生液压脉动,脉动药理达到一定值时,高压胶管会产生破损。其次液压系统总成中的某一个部件在运动过程中失效,会造成系统运行失效而被迫停车。

    在多年的使用过程中,我们应该了解液压升降机的使用方法及故障点。根据以上的分析,在设计中液压升降机液压系统针对性的提出了一些具体的技术要求。针对液压系统失效的情况,由于液压缸作为升降驱动力的主导,液压缸需随升降机构运动,此时液压缸既作为升降时的动力又作为施工作业时升降机的支撑构件。所以液压缸及其相连接的管路对整个安全系统起到主要的作用。因此,在设计中液压管路尽可能使用硬胶质内含钢网的油管,并保证油管的配管要求,减少因系统管路破裂和泄露造成液压系统失效的可能性。

    另外还有一种情况就是在液压系统正常的情况下,由于液压系统所属的电气系统失效(包括控制系统失效)造成系统突然被迫停车。大多情况下是在正常工作时发生突然停电的异常停机使人员滞留在高空不能下来,所以在日常的使用中一定要遵循厂家知道,注意保养和防护。

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.
