When 30t hydraulic press brake pressure drop too fast what is the reason?

In the whole process of RESEARCH and development of CNC bending machine, parts are found in place in the production process, and then carry out inspection. There is no difficulty in checking the abrasive first. Press the four-column CNC bending machine guide slide block, warm reminder of large working pressure value.

According to the running test, the guide rail slider and hydraulic pad have no problems. Check the water content of gear oil, and find that the amount of gear oil in the email box is also up to standard. The problem can be identified as: "The gate valves involved in the maintenance of working pressure are not harsh or the line leaks or the internal cylinder seals are damaged."

Therefore, please immediately check the filling valve and the sealing level of the pressure reducing valve according to the fuel pipe diagram in the actual operation instructions. After the inspection, the problem was found: in the oil pipeline, the oil pipeline leaked, resulting in serious leakage of gear oil, resulting in the working pressure reduced too fast.

CNC bending machine is generally composed of itself, power device, hydraulic transmission system three parts. It is generally composed of sound card frame, hydraulic cylinder components, part of the fitness movement and guiding equipment and other auxiliary tools and equipment. The processing technology regulation endangers the key elements of the construction mode of CNC bending machine itself. Because the processing technology of different CNC bending machine is various, so the structure of CNC bending machine itself is not the same.

According to the sound card frame, CNC bending machine can be divided into column type and vertical; According to the structure of the sound card frame, CNC bending machine can be divided into column beam type, single column type, frame structure type, stainless steel wire winding prestressed steel arch type. Its shell is composed of operating table, guide rail slider, bearing beam, vertical rod, locking mother and adjusting nut.
