液压升降平台http://www.rgsjpt.com/是使用非常广泛的货物垂直运输和高空作业设备,使用一段时间的液压升降平台经常会出现速度变慢的故障呢,影响液压升降平台速度的主要因素有油缸直径和液压油的流量。液压升降平台的速度与油缸活塞杆截面积成反比,与液压油流量成正比的。油缸直径时固定不变的,当液压升降平台速度变慢时应优先从液压油流量角度分析的。
1、液压升降平台速度变慢时,应该先检查液压系统是否有泄漏现象的,重点在检查液压管及接头、油缸、液压阀以及连接处等,如果出现液压油泄漏现象,应该根据实际情况正确处理好泄漏问题。
Hydraulic lifting platform slow, you should first check the hydraulic system for leaks, with emphasis on checking hydraulic pipes and fittings, cylinders, hydraulic valves and connections, etc., if there is leakage of hydraulic oil, should correctly handle the actual situation leakage.
2、对于采用电动机调速装置调整速度的液压升降平台,电动机调速装置也是一个非常重要的环节。这种调速方式的液压升降平台是通过调整电动机的速度来改变供油的流量,当速度变慢时,应该检查电动机调速装置的参数设置和硬件是否正常,同时还应该检查电动机调速装置的外接控制检测元件是否正常的,参数设置是最容易出问题的环节,不能忽视。
For the use of the motor speed control device to adjust the speed of the hydraulic lifting platform, the motor speed control device is also a very important part. This speed mode of hydraulic lifting platform is by adjusting the motor speed to vary the flow of oil, when the speed is slow, you should check whether the parameters of the motor speed control device and hardware normal, but should also check the motor speed control device whether external control testing element normal parameter settings are the most problematic areas, can not be ignored.
3、液压泵也是影响液压升降平台http://www.rgsjpt.com/液压油流量的重要因素,使用时间过长的液压泵,也是容易出现问题的,液压升降平台速度变慢时,应该检查液压泵供油流量是否稳定。
Pump is an important factor affecting hydraulic lifting platform hydraulic oil flow, the use of a hydraulic pump for too long, and it is prone to problems, hydraulic lifting platform slow, should check pump oil flow is stable.
