The rotor pump uses two synchronous rotors. The rotor rotates in the opposite direction under the synchronous drive of the main shaft and the auxiliary shaft, the volume of the pump changes, and there is no gap between the rotor and the pump shell. The rotor is continuously driven to push the medium from the suction end to the outlet end. Because of the symmetrical design, the conveying direction is reversible and positive suction and backwashing can be realized.
The rotor pump has a simple structure and can be repaired on-line without dismantling pipes or tools. It can be maintained online by replacing high-strength protective covers and simple mechanical seals. It is mainly reflected in the overall design of the pump cover, the versatility of accessories and simple structural design.
Using cam rotary pump to treat fecal sewage has the advantages of simple maintenance method and low cost. It is widely used in animal husbandry, agricultural breeding and dairy farms. Fecal sewage is mainly composed of animal faeces, particulates and long flocs. The water content is generally between 96% and 99%.
The rubber rotor of the rubber rotor pump in Shenghui pump industry mainly plays several functions:
1. Strong self-priming without diversion device: the process of fecal sewage treatment requires vertical self-priming, generally between 5-6 meters, with a height of 7 meters at low speed. And there is no need for vacuum auxiliary water diversion device.
2. Wear resistance and corrosion resistance: rubber coated rotors are resistant to corrosion in chemical properties, the service life of the rotor pump is long, and the replacement cycle of vulnerable parts is long.
3, no winding, no blockage: the inlet and outlet of the rotor pump is wide, long floc, animal hair will not block the inlet and outlet of the pump.
4. Simple installation and convenient maintenance: replace the rotor, the mechanical seal does not need to remove the pump from the pipeline, no need to separate from the motor, open the pump cover, and really realize on-line maintenance.
For the safety of operation, the rotor pump is also equipped with a pressure alarm device to ensure that the operating pressure is controlled below the set value and the safety of the equipment is ensured.
