Metering pump manufacturer, gear pump, also known as gear pump, in terms, also known as volumetric device, that is, the piston is in a cylinder, when one tooth enters the fluid space of another tooth, because the liquid is incompressible, so the liquid and the tooth can not occupy the same space at the same time, so the liquid will be mechanically squeezed out. Because of the constant tooth surface meshing, this phenomenon will continue to occur.

Metering pump supplier, so the outlet of the pump will also provide a continuous displacement, which is the same as each rotation of the pump. When the drive shaft is constantly rotating, the pump is constantly discharging liquid. Pump flow is directly related to pump speed. The concept of gear pump is very simple, and its most basic form is: two gears of the same size mesh with each other on a closely matched shell.

The inside of the shell is like an "8" shape, in which two gears are installed, and the outer diameter and two sides of the gear are closely matched. The material from the extruder enters into the middle of the two gears at the suction port and fills the space. With the rotation of the teeth, it moves along the shell and finally discharges when the two teeth mesh. In fact, the loss of fluid in the pump is small because it is used to lubricate both sides of the bearings and gears.

And the pump body can not be without clearance, for viscosity or density change of fluid, this pump will not be affected too much. If there are shock absorbers, such as filters or restrictors, on the side of the discharge port, the pump will push the liquid through them. If the shock absorber changes during operation, the filter screen is dirty and blocked.

Or the back pressure of the shock absorber increases, the pump will continue to maintain a constant flow until the weakest part of the unit reaches the mechanical limit (usually equipped with a torque limiter). For a pump speed, in fact, there is a limit, which mainly depends on the process fluid.
