The working principle of KCB gear oil pump

The KCB gear oil pump is a rotary pump that transfers liquid or pressurizes fluid depending on the change and displacement of the working volume formed between the pump cylinder and the meshing gear. The two enclosed spaces are composed of two gears, a pump body, and front and rear covers. When the gears are rotated, the volume of the space on the disengaging side of the gears is increased from small to large, a vacuum is formed, the liquid is sucked in, and the volume of the space on the gear meshing side changes from large to large. Small, and squeeze the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing lines of the two gears. The pressure at the outlet of the gear pump depends entirely on the resistance of the pump outlet. This type of pump has good self-priming, no need to pour liquid before each pump, simple and compact structure, easy to use and maintain. When the pump is automatically lubricated by the delivered liquid, no additional lubricating oil is required and the elastic coupling can be used to transmit the power to compensate for slight deviations caused by the installation, and play a good buffering role when subjected to hydraulic shock. KCB gear pump is composed of pump body, pump cover, gear, bearing sleeve and shaft end seal. The gear pump gears and shafts are nitrided and have high hardness and wear resistance. The gears are mounted in the shaft sleeve together with the shaft. All operating parts of the gear pump are lubricated with the media they convey. The four bearing sleeves in the pump are installed in the pump body, and the end clearance is automatically adjusted according to the working pressure. Therefore, the pressure of the gear oil pump is stable, the output flow pulsation is small, and the volume rate is high.

KCB gear oil pump ordinary type is suitable for conveying non-particle fiber, non-corrosive, the maximum use temperature does not exceed 200 °C; KCB high temperature gear oil pump, through the transformation of the pump processing technology, supporting high temperature seal, the use of temperature can reach 300 °C. Delivery viscosity is generally not more than 2000 cst, such as heavy oil, diesel oil, mechanical oil, and other liquids of similar nature. Can be used as transmission, booster, fuel injection, hydraulic and lubrication pumps. When gear pump transmission viscosity exceeds 2000cst, it should be equipped with a deceleration device. Stainless steel gear pumps are suitable for conveying solids-free corrosive media. When conveying flammable and explosive materials, the gear pump gear should be replaced with copper gear and mechanical seal, and the explosion-proof motor should be used at the same time. Special working conditions need to be customized.
