Comparison between rotor pump and gear pump:
The gear pump is driven by the prime mover to rotate on the shaft. The tooth top and end face are surrounded by the pump body and the front and rear end covers, and the material is transported by the engagement of two gears. When the gears engage and transport the material, the teeth run in between, producing a strong coefficient of friction. The gap between gears will quickly increase, the conveying efficiency will significantly decrease, and even become vacuum free. During the transportation process, gear pumps may cause damage, burning, and other damage to some materials when the teeth engage. The wheels are quickly replaced, and materials with high viscosity and particles cannot be transported. Gear pumps are commonly found in oil trapped imagination. The gear pump has large pressure pulsation and noise. So gear pumps cannot achieve true hygiene level and no leakage.
The principle of a rotary pump is to drive transportation through the operation of two rotors, with a certain gap between the rotors, no friction coefficient, and a long service life. Efficient and energy-saving, smooth transportation, low failure rate, reliable sealing, and low noise. Reliability and leak free time that can maintain continuous operation. Has strong self suction force. The composition of the conveying medium will not change.
