The internal gear pump adopts the principle of gear internal meshing, where the pitch circles of the inner and outer gears are closely adjacent to one side, and the other side is separated by a "crescent plate" on the pump cover. The active internal gear on the main shaft drives the external gear to rotate in the same direction. At the inlet, the gears separate from each other to form negative pressure and suck in liquid. At the outlet, the gears continuously engage and squeeze out the liquid.
Due to its unique structure, it is particularly suitable for conveying media with high viscosity, with a viscosity range of 0.2-1000000 cp.
1. The internal gear pump can deliver in reverse, as long as the motor direction is changed;
2. The internal gear pump body can rotate, and the inlet and outlet positions are at right angles, making it easy to select the inlet and outlet positions;
3. Internal gear pumps have convenient interfaces for connecting insulation or cooling media between the pump body, end cover, and bearing seat.
4. Internal gear pumps have the advantages of oil entrapment, smooth delivery, high efficiency, low noise, and long service life.
applicationBroadcasteditInternal gear pumps are suitable for transporting Newtonian or non Newtonian liquids in industries such as petroleum, chemical, coating, dye, food, oil, and medicine. The types of liquids transported can range from light and volatile liquids to heavy, viscous, and even semi-solid liquids.
texture of materialBroadcasteditThe materials of internal gear pumps include cast iron, cast steel, stainless steel, etc.
Supporting block floating internal meshing gear pumpBroadcasteditThe support block floating internal meshing gear pump adopts a modified involute tooth profile for both the inner and outer gears. A movable crescent plate is used to separate the high and low pressure chambers, and pressure compensation is formed in the radial direction, so that there is almost no gap seal between the inner and outer tooth tips and the crescent plate. The axial dynamic compensation disk ensures good sealing of the axial gap, minimizing the internal leakage of the pump. Low pressure 12Mpa, medium pressure 21Mpa, high pressure 33Mpa. This structure has high volumetric efficiency, complex structure, and high manufacturing cost. It is suitable for transporting various light and volatile liquids, up to heavy, viscous liquids, and even semi-solid liquids. Widely used in industries such as petroleum, chemical, grease, coatings, etc.Linear conjugate internal gear pumpBroadcasteditLinear conjugate internal meshing gear pump, the inner and outer gears are separated by fixed crescent plates, and the gears are meshed in a linear conjugate manner. The long-life characteristics of the linear conjugate internal meshing gear pump depend on wear resistance. There is an oil film protective layer between the internal mechanical surface and various functional parts, which is almost free of wear. Even with general hydraulic oil, the parts are not easily worn. In addition, by adopting the principle of pressure difference of bipolar pressurized bearings, the working conditions of the pump are improved and the service life of the pump is extended while increasing the working pressure. There are three pressure levels: low pressure 8Mpa, medium pressure 16 Mpa, and high pressure 32 Mpa. There are four positions of the oil outlet relative to the oil suction outlet: 0 °, 90 °, 180
