Both the scissor lift and the guide rail lift are powered by the hydraulic system, mainly because the hydraulic system has the characteristics of stable lifting, safety and large load. Even so, it is inevitable that the lifting speed of the hydraulic lift will slow down during the accumulated operation. What is the reason? Let's take you to know the reasons why the speed of the hydraulic elevator is slow.
1、 The speed of the hydraulic lift is inversely proportional to the cross-sectional area of the piston rod of the oil cylinder, and is directly proportional to the flow of hydraulic oil. Under the condition that the diameter of the oil cylinder is fixed, when the speed of the hydraulic lift becomes slow, the analysis shall be conducted from the Perspective of the flow of hydraulic oil.
2、 When the speed of the hydraulic lift becomes slow, check whether the oil supply flow of the hydraulic pump is stable. The hydraulic pipeline is also a very important link, and the hydraulic pump is one of the important factors affecting the hydraulic oil flow. Moreover, the hydraulic pump that has been used for a long time is prone to failure. Therefore, when the speed of the hydraulic lift becomes slow, the factor of hydraulic oil flow should also be given priority.
3、 If the quality of the hydraulic oil in the hydraulic lift is poor and there are many impurities, it is easy to cause blockage and slow down the lifting speed. Therefore, the quality of the hydraulic oil should be maintained.
