How to prevent cavitation

While the rest of the system cavitation can also occur , but the discussion here only to the pump .In order to prevent cavitation , make sure that the pump inlet pressure is highenough so that the oil pump oil parts ( piston , vane , gear teeth ) back from suction mouth filled space . Different types of pumps , the required pump inlet fluid pressure is different. Manufacturing technology , geometry, or a projection is to determine the minimum pressure ( maximum vacuum) factor.Inlet pressure must be measured at Hydraulic pipe fittings Hydraulic pipe fittings pump inlet . Low oil pressure value is a system that operates in the sea using petroleum oil based .For the pump , at an altitude of 1524m at both the pump from the mailbox to drop more than a small , imported oil pressure has been lower than the pump rating. But take a larger safety factor will ease this situation. The solution is to slow down the pump speed in order to reduce the inlet pressure oil pump parts are not " out " oil.In addition to excessive altitude and high pump speed,thismayresultinexcessivelyhigh vacuum pump inlet ( insufficient pressure ) Other factors include the oil from the tank when the pressure in the pump when pushing any factors can cause pressure drop ,
