The current hydraulic press is mainly caused by the deformation of the hydraulic cylinder hole. Usually, the end face of the hydraulic cylinder will be stuck on the card during assembly, resulting in the deformation and jamming of the hydraulic cylinder hole. In addition, if the central return spring is damaged, the cylinder bearing roller bearing Maintain the damaged state, the four-column hydraulic machine may wear out or the pump is damaged. Its hydraulic cylinders and other main components must be disassembled for inspection. Usually, replacement methods are used to exclude the damaged parts, because the possibility of repairing the damaged parts is small.
The pump on the four-column hydraulic machine is due to wear and tear of the pair after long-term operation, and the matching clearance is too large. The four-column hydraulic pump exerts pressure at high pressure, or the oil is insufficient. The cause of this phenomenon, in addition to the oil factor, if this phenomenon occurs, The wear must be more uniform. For severely worn and hydraulic cylinders, the replacement method is usually used. This repair method is quick and effective, but the economic benefits are not good. However, as long as the deformation of the hydraulic cylinder hole is not too serious, you can usually use fine adjustment or Grinding method to ensure that the size and position accuracy meet the tolerance requirements.
By replacing the outer diameter of the hydraulic cylinder to increase, the effect of the horizontal hydraulic machine is basically the same as that of the replacement parts. The foaming of the hydraulic oil is first popularized by science, but it is not the problem of foaming in the oil and deterioration, but it is caused by the action of the oil in the tank. If these bubbles flow into the hydraulic system, the four-column hydraulic machine may malfunction. If bubbles are found in the hydraulic oil, the operator separates the return area of the oil tank of the single-row hydraulic machine from the pump suction port to help separate the bubbles.
However, this method is difficult to separate tiny bubbles, and the efficiency is very low. In addition, a metal filter is set at the bottom of the fault, so that the filtration effect of the four-column hydraulic press is also very good. If the hydraulic press also has problems, you can use hydraulic oil with good foam removal performance. This reduces the possibility of air bubbles in the mixed oil, thereby controlling the possibility of air bubbles in the fuel tank.
