How to solve the problem that the four-column hydraulic press cooler is corroded

Four-column hydraulic press installation of the cooler, plays a very important role in the machine, because the hydraulic press is often a long time intensive work, fuselage temperature is too high, and once the machine temperature is too high will cause various failures, affecting the production of enterprises, in order to avoid this situation in the four-column hydraulic press installed on the cooler, the cooler can be the four-column hydraulic press produced by high temperature compressed air cooling, Remove a lot of moisture from the compressed air. Under long-term use, the phenomenon of corrosion of the cooler is found. What is the reason?

The main cause of corrosion is the material, the environment (water quality, gas) and the three major elements of electrochemical reaction, the selection of corrosion-resistant materials is an important measure to prevent corrosion. At present, tubular oil cooling is made of copper pipe with good heat dissipation, which has a strong tendency of ionization and will produce contact corrosion due to contact with different heavy metals. In addition, the environment of the cooler includes dissolved oxygen, water quality, temperature, flow rate and foreign matter of the cooling water.

Four column hydraulic press cooler corrosion troubleshooting method:

First, the following exclusion methods should be adopted: The cooling pipe of aluminum alloy, titanium alloy and other corrosion-resistant materials should be selected in the four-column hydraulic press. The stamped aluminum sheets are stacked together as heat transfer fins, which greatly increases the heat exchange area of the cooler and improves the production process.

Second, improve the cooling water quality. An effective water quality control device should be installed to stabilize the water quality of the cooling water system, and a filter or decontaminator should be installed. When the general open cooling water system can not meet the water quality requirements of the refrigeration equipment, it is appropriate to use closed cooling towers or set up intermediate heat exchangers.

Three, the corrosion of the cooler will have a very adverse impact on the hydraulic system of the four-column hydraulic press, in order to avoid this situation, in addition to regularly check the working condition of the cooler, once the anomaly occurs, it should be dealt with in time.
