The working principle of the gear pump in the pump housing has a pair of external gear, both ends of the gear cover cap. The housing, end cap and gear each interdependencies constitute a number of sealed working chamber. When the gear is rotated in the direction as shown in the figure, the right oil sucking chamber gradually disengages due to intermeshing gear teeth, the working chamber volume gradually increases to form a partial vacuum, the oil in the sump is sucked in, the interdental sump is filled, And with the gear rotation, the oil to the left pressure chamber to go. On the side of the pressure zone, as the teeth enter into engagement, the volume of the working chamber decreases and the oil is squeezed out. The suction and pressure zones are separated by intermeshing gear teeth and pump body. Gear pump according to the structure can be divided into external and internal meshing two. Internal gear pump applications less external gear pump. External gear pump has the advantages of simple structure and compact, easy to manufacture, low cost, insensitive to oil pollution, reliable operation, maintenance, long life, it is widely used in various low-pressure systems. With the gear pump (hereinafter referred to as external gear pump) in the continuous improvement of the structure, medium and high pressure gear pump applications gradually increased. At present, high pressure gear pump working pressure up to 14 ~ 212 MPa.
