Rotor pump working principle and characteristics
TLB cam rotor pump (Roots type infusion pump) Working principle: Cam pump also known as Roots pump, stainless steel rotor pump, cam pump, universal pump, high concentration pump, the motor through the reducer with two deceleration Synchronous anti-rotation of the rotor in the process of rotation in the suction (vacuum) at the inlet to inhale the material to be transported. The two rotors divide the rotor chamber into several small spaces and operate according to the order of abcd. When operating to position a, only the I chamber is filled with medium; to position b, part of the medium is enclosed in chamber B; to position c, when A Room also closed part of the medium; to position d, A, B room and Room II communicating, the medium is delivered to the discharge port. Rotor pump product features: Long service life: between the two to maintain a certain gap, no friction between each other, no wear and tear. No contact between the rotor and the rotor, no wear and tear for long-term use, smooth operation, low noise, high efficiency. Wide range of applications: delivery of high viscosity, concentration and the task of containing the media particles, screw replacement is the ideal product. The rotor pump is a positive displacement pump, the delivery flow can be more precise control can also be easily made variable pump. The output flow of the centrifugal pump can not be controlled, with the resistance increases with the decline; The rotor pump has a strong self-priming capability, while the centrifugal pump must be filled with liquid before moving the pump speed is very low, usually 200rmp Between 600rmp, the material being conveyed is smoothly output without its components being damaged. Centrifugal pump speed is high, the material being transported by a strong impact and the role of centrifugal force, so the centrifugal pump in the delivery of the mixture often have different substances in the composition, so that the quality of finished products. The rotor pump is the best choice to solve this problem, so it is particularly suitable for conveying the mixture or even the material containing solid particles, the pump can be used to transport high viscosity substances, it is also known as gel pump. The centrifugal pump without this feature. The pump can be easily made into a higher output pressure varieties, suitable for long-distance or high-resistance quantitative delivery. Compared with the screw pump: the two are the same volume pump, so its performance is basically similar - can be stable delivery of high viscosity substances, have a higher delivery pressure. However, one of the biggest shortcomings of the screw pump determines its inapplicability - the non-streamlined curved surface of the screw pump and many defects in the chamber determines the short life of it, and the pump due to the flow structure of the rotor and rotor chamber basic No dead spots and non-metallic parts, for high-viscosity media more easily transported. Energy-saving products: innovative design, low speed, high efficiency, screw pump, gear pump, energy saving <30%. The higher the operating speed of the pump, the greater the wear and tear of the material of the pumping element. According to experience, the wear rate decreases with the low speed, and the speed has roughly cubic relationship. Therefore, if the pump speed is doubled, the wear will be about eight times before the speed increase. The pump is driven through the reducer, usually 200 rpm to 600 rpm, the material transported by the original quality to maintain the same, can not afford any physical and chemical reactions. Sealing reliability: Due to low speed, the sealing surface is not easy to produce high temperature, less wear and tear, long service life. Jacket insulation type: The pump can be installed jacket insulation device, the temperature to 0 ℃ -250 ℃ range. Interchangeability: Various types of rotors of different shapes are fully interchangeable on the same type of pump. Diversity: to provide a variety of forms of transmission options and single-leaf, double leaf, clover and other forms of rotor, to meet different customers and different working conditions. Easy maintenance: The pump body has a wear-resistant bushing, pump shell material with high performance cast iron, ductile iron or stainless steel optional, and the use of MIP design greatly extends the service life of the pump. Pump casing lined with hardened steel, stainless steel, plastic or ceramic to protect the pump housing.
