RuiAn HuiHua Auto Oil Pump CO.,LTD.

The motor engine oil pumps are many types of oil pump, such as a gear-type oil pump, as well as rotor-type oil pump. Gear-type oil pump and rotor-type oil pump operating principle is the same, but still differ, compared to a gear-type oil pump, oil pump rotor structure is quite compact and form a relatively small size, very light weight, vacuum suction surface will be relatively large, so the inhalation of oil to a large amount of oil, oil of uniform performance is good. And there is a rotor-type oil pump big advantage is low cost, so the engine applications in small and medium lot, of course, it also has shortcomings, the power consumption is relatively large
