1, the quality of the oil is very important in the factors causing cavitation of the four-column oil press, if the quality of the anti-foam performance is poor, it will be vaporized to form foam, and then cause cavitation.
2, the reason for the oil level is too low or too high, some people for the oil level is too low resulting in insufficient circulating liquid flow, so it is easy to form bubbles.
3, if the oil level is too high, the same will cause gas to mix, but also cause cavitation phenomenon.
4. The oil temperature of the four-column hydraulic press is too high, and the air bubbles caused by the oil gas are increased, so the cavitation erosion phenomenon is increased.
5. The high frequency of liquid pressure change causes the formation and rupture speed of air bubbles to affect the parts with high frequency, so the cavitation speed is fast.
6, dozens of cooling water quality is not good, if the quality of cooling water is not good, which will have more corrosive media, which will form a joint effect of clothing and cavitation, accelerate cavitation phenomenon.
7, the maintenance of the cooling system is poor, if the maintenance of the cooling system is in place, the coolant pressure will be higher than the steam pressure, so the generation of cavitation is reduced. If the maintenance is not in place, it will cause the temperature and pressure market to accelerate the occurrence of cavitation.
8. Rough use conditions will also increase cavitation.
