Precision four column oil pressure cutting machine without pressure failure will appear many times, then automatic feed cutting machine is not pressure mainly caused by what reason? According to the general situation analysis, most of the pressure faults are hydraulic components and hydraulic accessories. Here we are to analyze the reasons:
Cylinder precision four column hydraulic cutting machine seal damage or leakage; cylinder seal leak is the most difficult to check, this method requires some basic mechanical technology; method is the removal of rod chamber pressure tubing, if the outflow of oil seal leak proof, proof of normal anyway.
Solution: replace the seal or oil cylinder.

The external joint or seal of the automatic feed cutting machine leaks oil, the external oil leaking is more obvious, the general static state and pressure state can be observed by the naked eye.
Solution: repair the oil leaking parts or replace parts.
The hydraulic valve precision four column hydraulic cutting machine leakage or damage; establish the hydraulic system of any leakage will affect the pressure; the hydraulic valve leakage is the most difficult to find such a leak, most commonly for internal leakage naked eye is difficult to observe; there is a simple method is not necessarily quasi but very effective, is put on the work sets up to the highest after shutdown, see table would decline, such as there is a leak proof system from other joint external teeth can be roughly written. Judge hydraulic valve leaks.
Solution: replace the hydraulic valve.
The oil is less or the quality of the oil is too poor; this will result in the suction or early wear of the oil pump of the automatic feed cutter.
Solution: please keep enough oil and oil quality, and change the hydraulic oil regularly on time.
The oil pump is empty or damaged. The oil pump is the core component of the whole system, and the whole system is pressurized by the oil pump. So the influence of the oil pump on the pressure of the system is enormous if it is inhaled or damaged. If the oil pump is empty or damaged, many bubbles in the hydraulic oil will be seen, or there will be a different noise. The most direct method is to use the pressure gauge directly to the oil pump test (this method requires auxiliary components).
Solution: replace or repair the oil pump.
