The phenomenon of trapping oil is an inevitable result to ensure oil absorption cavity and oil exhaust cavity are not collude with each other. It directly affects the working performance and service life of the gear pump. This article through analyzing the root cause of it put forward a new way to using an external oil circuit to eliminate it. Adding such an external oil circuit to the gear pump, can make the dead volume linked to oil exhaust cavity when the dead volume is decreasing and make the dead volume linked to oil absorption cavity when the dead volume is increasing. This way eliminates the trapped oil compression and expansion, so as to achieve the purpose of thoroughly eliminate the phenomenon of trapping oil.
