HYDRAULIC GEAR PUMP adopts the principle of gear internal meshing, the pitch circle of the internal and external gears is close to one side, and the other side is separated by the "crescent plate" on the pump cover. The active internal gear on the main shaft of the HYDRAULIC GEAR PUMP drives the external gears to rotate in the same direction. The gears are separated from each other at the inlet to form negative pressure to inhale the liquid, and the gears are continuously embedded and meshed at the outlet to squeeze the liquid out.

Support block floating HYDRAULIC GEAR PUMP
Support block floating type HYDRAULIC GEAR PUMP, the internal and external gears adopt modified involute tooth shape, the high and low-pressure chambers are separated by movable crescent plates, and pressure compensation is formed in the radial direction so that a few No gap sealing. The axial dynamic compensating disc ensures good sealing of the axial gap, which minimizes the internal leakage of the pump. Low-pressure 12Mpa, medium pressure 21Mpa, high-pressure 33Mpa. The internal gear pumps of the support block floating type have high structural volume efficiency, complex structure, and high manufacturing cost. This HYDRAULIC GEAR PUMP is suitable for conveying all kinds of light, volatile liquids, up to heavy, viscous liquids, and even semi-solid liquids. Widely used in petroleum, chemical, oil, paint, and other industries.
Linear conjugate internal meshing gear pair tooth profile structure, the tooth profile curve of the gear is a straight line, and the tooth profile of the ring gear is divided into two parts. The gear tooth part is the working tooth profile, which is conjugate with the linear tooth profile of the gear, and contacts with the gear tooth surface during operation. The root of the gear tooth is a symmetrical trapezoidal groove, and the two sides of the trapezoidal groove do not contact the gear tooth surface when working. In linear conjugate HYDRAULIC GEAR PUMP, the internal and external gears are separated by fixed crescent plates, and the gears are meshed by the linear conjugate. The long life of linear conjugate internal gear pumps depends on wear resistance. There is a layer of oil film protection layer between the internal mechanical surface and various functional parts, which has almost no wear. Even if ordinary hydraulic oil is used, it is not easy to wear parts. In addition, the linear conjugate HYDRAULIC GEAR PUMP adopts the principle of pressure difference of bipolar pressurized bearings, which not only increases the working pressure but also improves the working conditions of the pump and prolongs the service life of internal gear pumps. There are three pressure fractions: low-pressure 8 Mpa, medium-pressure 16 Mpa, and high-pressure 32 Mpa. There are four positions of the oil outlet relative to the oil suction port: 0°, 90°, 180°, and 270°, which are convenient for users to choose to pipe. Linear conjugated HYDRAULIC GEAR PUMP has a simple structure and low manufacturing cost.
