Working Principle
Relying on the two rotors that rotate synchronously in the opposite direction, a suction force is generated at the inlet during the rotation process, thus sucking in the materials to be conveyed. The two rotors divide the rotor chamber into several small spaces. As the rotors rotate, the medium in these small spaces is successively conveyed to the outlet.
Structural Features
Elastomer Rotor: The rotors made of elastomer materials, such as twisted-leaf rubber rotors, have good wear resistance, corrosion resistance, and flexibility. The sealing between this kind of rotor and the pump body is excellent, which can effectively prevent the leakage of the medium. At the same time, it can also reduce wear and noise.
Synchronous Gear Transmission: Through a pair of synchronous gears in the synchronous gearbox, the two rotors are driven to rotate synchronously in the opposite direction, ensuring the accuracy and stability of the rotor movement and making the operation of the pump more reliable.
Compact Structure: Components such as the pump body, gearbox, and reduction gearbox are integrated into one unit, featuring a compact structure, small floor space, and being convenient for installation and maintenance. Meanwhile, this structure also helps to reduce the vibration and noise of the pump during operation.
Performance Parameters
Flow Rate: The flow rate range of different models of CRP cam rotor pumps varies. Generally speaking, the flow rate can be adjusted within a relatively wide range to meet the needs of different users. For example, the flow rate of some small CRP-3Z-10 cam rotor pumps may be between several cubic meters and dozens of cubic meters per hour, while the flow rate of large pumps can reach hundreds of cubic meters per hour.
Head: The head is also an important performance index of the cam rotor pump. It can usually reach dozens of meters or even hundreds of meters, meeting the requirements of different conveying heights.
Self-priming Height: It has a strong self-priming ability. The self-priming height can generally reach several meters, and for some high-performance pumps, the self-priming height can even reach more than 8 meters. There is no need to fill the liquid before starting, and it can quickly suck in the medium and start conveying.
Rotational Speed: The rotational speed can usually be adjusted within a certain range, generally ranging from dozens of revolutions per minute to hundreds of revolutions per minute, and can be adjusted according to the actual conveying requirements.
Application Fields
Petrochemical Industry: It can be used for crude oil transportation, oil introduction and tank cleaning of refined oil products, and the transportation of volatile media in chemical processes, etc. It can adapt to the transportation of various light oil products and chemical products, including corrosive media such as strong acids and alkalis.
Sewage Treatment Industry: It is used for sewage lifting, sludge transportation, and sewage discharge from septic tanks, etc. It can effectively treat sewage containing impurities such as solid particles and fibers, avoid blockages, and ensure the normal operation of the sewage treatment system.
Food and Beverage Industry: It is suitable for the transportation of food-grade media, such as sauces, jams, honey, milk, etc. It has a small shearing force on the medium and can maintain the original quality and taste of the food.
Pharmaceutical Industry: It can be used for transporting various liquid medicines, ointments, and other media in the pharmaceutical process, meeting the requirements of the pharmaceutical industry for hygiene, safety, and accurate transportation.
Advantages
High Efficiency and Energy Saving: The operation efficiency of the unit is as high as 75%-85%. Compared with traditional pump products, it can effectively reduce energy consumption and save operation costs.
Gas-Liquid Mixed Transportation: It has a unique gas-liquid mixed transportation function and can handle gas and liquid simultaneously during the transportation process, which is suitable for various complex working conditions.
Contactless Operation: There is no contact between the rotor and the lining plate, and there are no problems such as sliding friction, wear, and heat generation. It fundamentally solves the problems of wear, heat generation, and poor reliability of traditional pumps such as vane pumps and metal rotor pumps, and prolongs the service life of the pump.
Convenient Maintenance: The structure is relatively simple, and online maintenance is convenient. Generally, the replacement of accessories can be completed within 30 minutes without the need to remove the pipeline, reducing the maintenance time and cost and improving the utilization rate of the equipment.
