Is there a variable gear pump? Is the gear pump a variable pump or a fixed pump? There are no variables in the gear pump. The gear pump is a fixed pump because the suction chamber and the pressure chamber of the gear pump are unique and cannot be adjusted. The pumps with adjustable suction and pressure chambers are variable pumps, such as vane pumps and plunger pumps.
青海快3Working principle and structure of gear pump
The working principle of the gear oil pump is very simple, that is, its most basic form is that two gears of the same size mesh with each other and rotate in a tightly matched housing。 The inside of this housing is similar to an "8" shape, with two gears installed inside , The outer diameter and both sides of the gear are closely matched with the housing。 The material from the extruder enters the middle of the two gears at the suction port and fills this space。 It moves along the housing with the rotation of the teeth and is finally discharged when the two teeth are engaged。
In terminology, a gear pump is also called a positive displacement device, that is, like a piston in a cylinder, when one tooth enters the fluid space of another tooth, the liquid is mechanically squeezed out。 Because the liquid is incompressible, the liquid and the teeth cannot occupy the same space at the same time, so that the liquid is excluded。 Due to the continuous meshing of the teeth, this phenomenon occurs continuously, and thus provides a continuous discharge amount at the outlet of the pump。 The discharge amount is the same for each revolution of the pump。 As the drive shaft rotates without interruption, the pump discharges fluid without interruption。 The flow rate of the pump is directly related to the speed of the pump。

The gear pump is driven by an independent motor, which can effectively block upstream pressure pulsations and flow fluctuations. The pressure pulsation at the outlet of the gear pump can be controlled within 1%. The use of a gear pump on the extrusion production line can increase the flow output speed, reduce the shearing and residence time of the materials in the extruder, and reduce the extrusion temperature and pressure pulsation to improve productivity and product quality. Are there any variables for the gear oil pump? Is the gear oil pump variable or fixed pump content here, I hope to help everyone.
