CH, CHY gear pump

The gear pump has the characteristics of simple structure, convenient processing, small size, light weight, strong self-absorption ability, and insensitive to oil pollution. Therefore, the gear pump is widely used. CH, CHY gear pumps are volumetric pumps. Its unique structure has self-priming ability, stable pulsation when delivering oil, high pressure, low wear, long service life, wide application and high efficiency.

The gear pump is a rotary pump that transfers or pressurizes a liquid 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.

The CH, CHY gear oil pumps are equipped with safety valves as overload protection, and the full return pressure of the safety valve is 1.5 times the rated discharge pressure, which can be properly adjusted within the user's actual process requirements. However, this safety valve cannot be used for long-term operation of the pressure reducing valve, and can be installed separately on the pipeline when needed.

CH, CHY gear oil pumps are widely used in national defense research, petroleum, chemical, power generation, metallurgy, transportation, pharmaceutical, food and other departments. According to the needs of the process can also be sent to generate heat transfer oil pump, asphalt pump, anti-corrosion pump.

CH, CHY gear oil pumps are used to deliver various mediums with mechanical properties such as mechanical oils, turbine oils, etc. that do not contain solid particles, with viscosities below 200°E (1500 mPa.s). The temperature is not higher than 120. °. Volumetric pump. Its unique structure has self-priming ability, stable pulsation when delivering oil, high pressure, low wear, long service life, wide application and high efficiency.
