German abanova pump abanova model abanova price

The most basic form of the abanova pump consists of two gears of identical size meshing and rotating within a closely fitted housing. The interior of this housing resembles the shape of an '8', with the two gears installed inside; the outer diameters and sides of the gears fit tightly against the housing. Material from the extruder enters between the two gears at the suction inlet, fills this space, moves along the housing as the teeth rotate, and is finally discharged when the teeth mesh.

abanova pump motor features

1) Compact structure, small volume, and light weight: Composed of a front cover, intermediate body, and rear cover made of aluminum alloy, gears made of alloy steel, and pressure plates made of aluminum alloy. Two DU bearings are press-fitted into the front and rear covers respectively. DU material is an ideal bearing material for gear pumps, significantly extending the service life of the gear pump. 2) Reliable operation: The pressure plate is the main component for radial and axial pressure compensation, reducing bearing load and automatically adjusting the axial clearance of the gear pump, thereby effectively improving the performance indicators and operational reliability of the gear pump. The GM5 and GPC4 series gear motors offer four structural configurations: single rotation direction without front bearing, double rotation direction without front bearing, single rotation direction with front bearing, and double rotation direction with front bearing. Gear motors with front bearings can withstand both radial and axial forces. 3) High speed and high pressure: High speed ranges from 3000 to 4000 rpm, with a theoretical torque of 17N.m (N·m) to 64N.m, reaching up to 20-25MPa. 4) Connection methods suitable for imported machinery and engineering equipment: Complies with SAE and national standard GB for mounting flanges, shaft extensions, and inlet/outlet port connections. Widely applicable to hydraulic systems in automobiles, tractors, engineering machinery, agricultural machinery, and other mechanical equipment.

abanova pump working principle

The concept of a gear pump is straightforward. Its most basic form consists of two gears of identical size meshing and rotating within a closely fitted housing. The interior of this housing resembles the shape of an '8', with the two gears installed inside; the outer diameters and sides of the gears fit tightly against the housing. Material from the extruder enters between the two gears at the suction inlet, fills this space, moves along the housing as the teeth rotate, and is finally discharged when the teeth mesh. A gear pump is also known as a positive displacement device. Similar to a piston within a cylinder, when one tooth enters the fluid space of another tooth, the liquid and the tooth cannot occupy the same space simultaneously because the liquid is incompressible. Consequently, the liquid is mechanically squeezed out. Due to the continuous meshing of the teeth, this phenomenon occurs continuously, providing a continuous discharge volume at the pump outlet. The discharged volume per revolution remains constant. As the drive shaft rotates uninterrupted, the pump discharges fluid without interruption. The pump flow rate is directly related to the pump speed. In practice, there is a small amount of fluid loss within the pump, as some fluid is used to lubricate the bearings and the sides of the gears. Furthermore, a perfect zero-clearance fit within the pump body is impossible, preventing 100% of the fluid from being discharged from the outlet. Therefore, minor fluid loss is inevitable, meaning the pump's operating efficiency cannot reach 100%. However, the pump can still operate effectively, achieving efficiencies of 93% to 98% for most extruded materials. This pump is not significantly affected by changes in fluid viscosity or density during the process. If a damper, such as a filter screen or restrictor, is placed on the discharge side, the pump will push the fluid through them. If this damper changes during operation—for example, if the filter becomes dirty or clogged, or if the back pressure of the restrictor increases—the pump will maintain a constant flow rate until the mechanical limit of the weakest component in the system is reached (a torque limiter is usually installed). There is actually a limit to the pump's speed, which primarily depends on the process fluid. If pumping oil, the pump can rotate at high speeds; however, if the fluid is a high-viscosity polymer melt, this limitation increases significantly. It is crucial to fill the space between the two teeth on the suction side with high-viscosity fluid. If this space is not fully filled, the pump cannot discharge an accurate flow rate. Therefore, the PV value (pressure × flow velocity) is another limiting factor and a process variable. Due to these limitations, gear pump manufacturers offer a range of products with different specifications and displacements (volume discharged per revolution). These pumps are matched to specific application processes to optimize system capacity and price.

abanova pump usage precautions

In addition to preventing dry running, overload, air ingestion, and excessive suction vacuum, key management points for vane pumps include: 1) If the pump rotation direction changes, the suction and discharge directions also change. Vane pumps have a specified rotation direction and reverse rotation is not permitted. Because the rotor vanes slots are inclined, the vanes have chamfers, the bottom of the vanes connects to the discharge chamber, and the throttle grooves on the valve plate and the suction/discharge ports are designed for a specific rotation direction. Reversible vane pumps must be specially designed. 2) Vane pump assembly: The valve plate and stator must be correctly positioned using locating pins. The vanes, rotor, and valve plate must not be installed backwards. The suction area of the stator's inner surface is most prone to wear; if necessary, it can be flipped for installation so that the original suction area becomes the discharge area, allowing continued use. 3) Disassembly and assembly: Ensure working surfaces are clean, and the hydraulic oil should be well filtered during operation. 4) Excessive clearance between the vanes and the vane slots will increase leakage, while insufficient clearance will prevent the vanes from extending and retracting freely, leading to operational malfunction. 5) The axial clearance of the vane pump has a significant impact on ηv. 1) Small pumps - 0.015 to 0.03mm2); Medium-sized pumps - 0.02 to 0.045mm6. Oil temperature and viscosity: Generally, the temperature should not exceed 55°C, and the viscosity should be between 17 and 37mm2/s. If the viscosity is too high, oil suction becomes difficult; if the viscosity is too low, leakage becomes severe. As a pump product, 'vane pump' often refers to sliding vane pumps. Virtually all vane pumps are sliding vane pumps.
