What should I do if noise is generated during the operation of the hydraulic cylinder of a four-column hydraulic machine?

Hydraulic press is a machine that uses hydrostatic pressure to process metal, plastic, rubber, wood, powder and other products. It is often used in pressing processes and press forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet deep drawing, powder metallurgy, pressing and so on. So what should be done when the hydraulic cylinder of a four-column hydraulic press produces noise during operation?
1. Clean the filter

The hydraulic cylinder has a special oil filter to remove all kinds of dirt or impurities in the hydraulic oil, because long-term work in a dusty or polluted environment will inevitably cause pollutants to fall into the oil, which is generated during work Long-term accumulation of noise will easily block the filter hole of the filter and it will not be able to filter the oil. How to solve the problem of impurity immersed in the hydraulic cylinder oil will cause noise during the operation of the equipment, by replacing the new oil or removing the obstruction Can solve the noise.

2. Fill up the oil level

In many cases, the oil suction position of the hydraulic cylinder is too high and the oil level is insufficient during use. The suction pipe will be exposed to the oil surface and cannot suck oil normally. The hydraulic cylinder will produce noise during frequent work without the moisture of lubricating oil. Fill the oil directly to the oil standard and lower the oil suction position to reduce the noise.

3. Adjust the concentricity of pump and motor coupling

If the driving shaft of the hydraulic cylinder and the motor coupling are not concentric, twisting and friction will occur. If the friction is severe, a lot of noise will be generated. The user only needs to adjust the concentricity of the pump and the motor coupling. Can successfully eliminate the appearance of noise.
