液壓升降平臺http://m.kkwl.net/是使用非常廣泛的貨物垂直運輸和高空作業(yè)設備，使用一段時間的液壓升降平臺經(jīng)常會出現(xiàn)速度變慢的故障呢，影響液壓升降平臺速度的主要因素有油缸直徑和液壓油的流量。液壓升降平臺的速度與油缸活塞桿截面積成反比，與液壓油流量成正比的。油缸直徑時固定不變的，當液壓升降平臺速度變慢時應優(yōu)先從液壓油流量角度分析的。

1、液壓升降平臺速度變慢時，應該先檢查液壓系統(tǒng)是否有泄漏現(xiàn)象的，重點在檢查液壓管及接頭、油缸、液壓閥以及連接處等，如果出現(xiàn)液壓油泄漏現(xiàn)象，應該根據(jù)實際情況正確處理好泄漏問題。
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、對于采用電動機調速裝置調整速度的液壓升降平臺，電動機調速裝置也是一個非常重要的環(huán)節(jié)。這種調速方式的液壓升降平臺是通過調整電動機的速度來改變供油的流量，當速度變慢時，應該檢查電動機調速裝置的參數(shù)設置和硬件是否正常，同時還應該檢查電動機調速裝置的外接控制檢測元件是否正常的，參數(shù)設置是最容易出問題的環(huán)節(jié)，不能忽視。
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、液壓泵也是影響液壓升降平臺http://m.kkwl.net/液壓油流量的重要因素，使用時間過長的液壓泵，也是容易出現(xiàn)問題的，液壓升降平臺速度變慢時，應該檢查液壓泵供油流量是否穩(wěn)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.
