The main reason for this failure is blockage and sediment retention on the cooling pipe wall of the hydraulic press, forming hard blocks and pipe scale, which reduces the heat dissipation and heat exchange function. In addition, the lack of cooling water and the accumulation of air in the water and oil cavity of the hydraulic cooler will also cause the cooling performance to decrease.
The solution is to first adopt a structure that is difficult to block and easy to clean from the design, but there seem to be few methods at present. When selecting the cooling capacity of hydraulic machine cooler, we should try our best to take practice as the basis and leave a large margin, generally increasing the capacity by 10% ~ 25%. Mechanical methods such as brush, pressure, water, steam and other scrubbing and flushing are used when necessary, or chemical methods (such as Na2C03 solution and cleaning agent, etc.) to clean; Increase the water intake or use lower temperature water for cooling; Unscrew the screw plug for exhaust; Clean the inner and outer surfaces of the hydraulic press.
