How do manufacturers of cam rotor pumps truly achieve full online maintenance?
The rotor pump uses two synchronous rotors. The rotor rotates in the opposite direction under the synchronous driving of the main shaft and the counter shaft, the volume of the pump changes, and there is no gap between the rotor and the pump casing. The rotor is continuously driven, pushing the medium from the suction end to the outlet end. Due to the symmetrical design, the conveying direction is reversible, which can realize positive suction and reverse flushing.
The rotor pump has a simple structure and can be repaired online without disassembling pipes or special tools. It can be maintained online by replacing high-strength protective covers and simple mechanical seals. Mainly reflected in the overall design of the pump cover, the versatility of the accessories is strong, and the structural design is simple.
The cam rotary pump is used to treat fecal sewage, the maintenance method is simple, and the cost is low. Widely used in animal husbandry, agricultural breeding and dairy farms. Fecal sewage is mainly composed of animal manure, particulate matter and long floc. The water content is generally between 96% and 99%.
The rotor of the cam rotor pump is coated with rubber, which mainly serves several functions:
1. Strong self-priming, no need for water diversion device: the process of fecal sewage treatment requires vertical self-priming, generally between 5-6 meters, and 7 meters high at low speed. And no vacuum-assisted water introduction device is required.
2. Abrasion and corrosion resistance: The rubber-coated rotor is chemically resistant to corrosion. The cam rotor pump has a long service life and a long replacement cycle of wearing parts.
3. No entanglement and no clogging: The inlet and outlet of the cam rotor pump are large and long flocks. Animal hair will not block the inlet and outlet of the pump.
4. Simple installation and convenient maintenance: When replacing the rotor, there is no need to remove the pump from the pipeline when the mechanical seal is needed, and it is not necessary to separate it from the motor. Just open the pump cover, and truly complete online maintenance.
For the safety of operation, the cam rotor pump is also equipped with a pressure alarm device for the pump, which can ensure that the operating pressure is controlled below the set value to ensure the safety of the equipment operation.
The cam rotor pump is a positive displacement pump, which has the characteristics of low speed, strong suction capacity, mixed gas-liquid-solid transportation, and low requirements for impurity filtration. It is widely used in crude oil extraction, storage, transportation, refining and other fields.
