The pump cavity of the gear oil pump is composed of two gears, a driven wheel and a driving wheel.
When the liquid enters from the suction port and fills this space, as the gear rotates, the liquid is discharged from the discharge port. Due to the continuous meshing of the gears,
The liquid will be continuously discharged from the discharge port.Every time the pump rotates, the amount of liquid discharged is the same, so the flow rate of the pump is related to the speed of the pump.
2. The structure of the gear oil pump
It is mainly composed of pump body, gears, safety valve, sealing components and other components.
3. Material and applicable medium of gear oil pump
①Cast iron material: suitable for fluid media that has lubricating properties and does not contain solid particles and fibers in ordinary industrial conditions.
②Explosion-proof material: suitable for media in which flammable and explosive fluids do not contain solid particles and fibers in industrial conditions.
③Stainless steel material: suitable for corrosive fluids that do not contain solid particles and fibers in industrial conditions. This material is suitable for fluid media with hygienic requirements in food processing.
4. The importance of pressure relief valve
The safety valve is equipped with a protective function for the generator. During the working process of the pump,
Pressure will be generated in the pump cavity. When the pressure exceeds 1.5 times the rated pressure, the safety valve will automatically open, so that the delivered liquid will begin to flow back in the pump cavity.
Thereby avoiding the overload operation of the generator. The safety valve can be adjusted according to actual needs within the allowable discharge pressure range.
"Attention" safety valve can not be used as a pressure reducing valve for a long time, if necessary, it can be installed on the pipeline.
5. Types of sealing components
① Packing seal: It has the characteristics of high temperature resistance, strong wear resistance, and high cost performance.
②Mechanical seal: high temperature resistance, corrosion resistance, outstanding sealing.
The kcb series gear oil pump is widely applicable because of its small size, simple structure, convenient use and stable performance.
