Abstract
The utility model discloses an oil pump of a safety regulating valve. The oil pump comprises a pump body 1, a pump cover 2, an outer rotor 3, an inner rotor 4, a transmission shaft 5 and the safety regulating valve 6. The safety regulating valve 6 is arranged above the pump cover 2; after the pump cover 2 is buckled with the pump body 1, the safety regulating valve 6 precisely corresponds to an oil inlet and an oil outlet on the pump body 1; a flat-square tube 51 is arranged at the small end of the transmission shaft 5, a transmission groove 52 is formed at the large end, and the middle of the transmission and the inner rotor 4 are in interference connection and are sleeved on the outer rotor 3, and then the middle of the transmission is installed in shaft holes of the pump body 1 and the pump cover 2; the flat-square tube 51 of the transmission shaft 5 is directly driven by a main shaft; and the transmission groove 52 at the other end drives other accessories. The oil pump can improve the stability of oil pressure in a circulating oil duct on the basis that the safety of the oil pump, pipelines and a filter are guaranteed, has the buffer protective effect for impact of over high oil pressure caused by unexpected fault of an engine, reduces the power consumption, improves the safety and the reliability of a whole lubricating system, and prolongs the service life.
Description
Technical field
The utility model relates to a kind of oil pump of engine lubrication system, particularly a kind of safety regulating valve oil pump.
Background technique
Have now and the supporting oil pump of motor, be provided with a safety valve,, prevent breaking of oil pump and oil duct and filter in order to the safety pressure of controller oil pump.Its deficiency is: when the motor ultra high speed is moved, can not guarantee the pressure stability of whole oil-way system, when the oil pressure in the circulating oil path is higher,, influence the safety of motor moving system easily because of the too high annex that damages oil-way system of main oil gallery engine oil pressure.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes on the prior art, and provide a kind of safety regulating valve oil pump, engine oil pressure with control and stable circulation oil circuit, cut down the consumption of energy, reduce power loss, avoid oil pressure too high and cause breaking of pipeline and filter cleaner, improve Security, reliability and the working life of oil pump.
The technical solution of the utility model is: a kind of safety regulating valve oil pump comprises the pump housing, pump cover, external rotor, internal rotor, transmission shaft and safety regulating valve; Safety regulating valve is arranged on the top of pump cover, and behind pump cover and pump housing fastening, safety regulating valve is just in time corresponding with filler opening and oil outlet on the pump housing; The transmission shaft small end is provided with flat side, big end is provided with driving groove, middle part and internal rotor interference be connected overlap install external rotor after, attach it to again in the axis hole of the pump housing and pump cover, the flat side of its transmission shaft is subjected to the direct transmission of main shaft, and the other end driving groove is the usefulness of other annexes of transmission then.
The further technological scheme of the utility model is: safety regulating valve comprises valve body, steel ball valve, spring and plug screw, steel ball valve and spring are positioned at the cavity of valve body, plug screw is installed in an end of valve body, and the other end of valve body and middle part are respectively equipped with oil inlet hole and draining hole.
The utility model can be on the basis that guarantees oil pump and pipeline and filter safety; improve the stability of oil pressure in the circulating oil path; prevent the motor accident and produce the buffer protection function that oil pressure is crossed HI high impact; reduce the power consumpiton of oil pump; improve the Security and the reliability of haveing suffered lubrication system, prolong the working life of oil pump.
Below in conjunction with figure and embodiment detailed structure of the present utility model is further described.
