How to debug the stroke speed of the hydraulic jack? For hydraulic jacks, how can we debug to the speed we need and meet various regulations? Let me come to you for an in-depth analysis of the process and common problems of its travel speed debugging.
The speed debugging should be carried out one by one. When debugging one circuit, the other circuits should be in the closed state. And when adjusting the speed, it is necessary to adjust the clearance of the slide rail and the position accuracy of the moving parts of the hydraulic jack at the same time, so as not to cause the transmission parts to be too tight and stuck.
If there is gas in the hydraulic jack, the speed will be unstable. Open the automatic exhaust valve of the hydraulic jack during the debugging process, and the tensioning jack is designed to remove the gas that stays in the hydraulic jack. For the hydraulic jack without automatic exhaust valve, it is necessary to make the hydraulic jack move back and forth several times, at the same time loosen the three-way joint of the oil return chamber during operation, and see that the hydraulic oil overflows from the flange connection. Tighten the tee joint.
During the adjustment of the stroke speed of the hydraulic jack, the buffer device should be adjusted at the same time until the stability requirements of the hydraulic jack's required structure are met. If the buffer device of the hydraulic jack cannot be adjusted, the hydraulic jack must be disassembled, debugged on the test bench to meet the standard, and then the computer is installed and debugged.
When the hydraulic jack synchronous circuit is changing speed, the two hydraulic jacks should be adjusted to the same development position first, and then the speed adjustment should be carried out, and the adjustment should be carried out under normal steam pressure and normal temperature. For high hydraulic transmission systems, the speed changes should be observed under the condition of support.
After adjusting the speed of the hydraulic jacks, adjust the stroke position, program flow and safety interlock of each hydraulic jack. Email address: info@gaodetec.com
