How to operate the hydraulic jack correctly when adjusting the speed?
Hydraulic Jack must adjust its speed correctly in application. Only in this way can its performance be fully embodied. Then how should we operate correctly? The following points are elaborated in detail for you:
In the process of debugging, the buffer device should be adjusted at the same time until the stability requirement of the mechanism with Jack is satisfied.
If the electro-hydraulic Jack buffer device is not adjustable, the electro-hydraulic Jack should be removed and debugged after being qualified on the test bench.When adjusting the speed of synchronous circuit of electro-hydraulic jack, two jacks should be adjusted to the same starting position before speed adjustment. Speed regulation should be carried out under normal oil pressure and normal oil temperature. For hydraulic systems requiring high speed and stability, it is necessary to observe the speed change under load.
After speed adjustment, adjust the travel position, program action and safety interlocking device of each electric hydraulic jack. Only when each index meets the design requirements can the trial run be carried out. Speed debugging should be carried out one by one (hydraulic system drive and control mechanism).
When debugging one circuit, the rest should be closed (no oil). When adjusting the speed, the clearance of the guide rail and the position accuracy of the moving parts of the electro-hydraulic Jack must be adjusted at the same time, so as not to cause the transmission parts to be too tightly jammed.
If there is air in the hydraulic jack, the speed is unstable.Open the exhaust valve of the electric hydraulic jack to remove the air in the jack during debugging. For the electro-hydraulic jack without exhaust valve, the electro-hydraulic Jack must be moved back and forth several times. At the same time, the pipe joints of the oil chamber should be loosened properly during the moving process. When oil leakage occurs at threaded joints, the pipe joints shall be tightened.This is the correct ways to operate hydraulic jack when adjusting speed. We must operate correctly according to the instructions so that their performance can be fully displayed.
