1. The principle of cavitation formation. With the increase of the pressure of the four-column hydraulic press, the gas in the oil turns into bubbles. When the pressure rises to a certain limit value, these bubbles will burst at high temperature, so that high temperature and high pressure gas will quickly act on the surface of the part.
2, the reason for the coolant. The anti-corrosion medium contained in the coolant of the four-column hydraulic machine is prone to certain chemical reactions, and the cavitation rate will be accelerated under their interaction. If the cooling system is well maintained, cavitation can be prevented.
3. The quality of hydraulic oil is unqualified. Ensuring the quality of hydraulic oil is the main factor to prevent cavitation in a four-column hydraulic press.
4, caused by improper manufacture and maintenance of the four-column hydraulic press.
