双转子泵的原理是
The principle of a dual rotor pump is to use two interlocked rotors to rotate under the action of a cam, causing a change in volume, thereby achieving the suction, discharge, and transportation of liquids. This pump is a positive displacement pump that forms a continuous flow of liquid through the rotation of the rotor relative to the pump body. The main structure of a dual rotor pump includes a drive shaft, rotor, pump body, and seals. The rotor is driven by a pair of external synchronous gearboxes to achieve synchronous reverse rotation, thereby creating a high vacuum degree and discharge pressure. This type of pump has strong self suction force, high lift force, and can ensure short-term dry running, with the characteristics of reliability, durability, energy saving, and stable efficiency. It is particularly suitable for transporting various viscous or particulate media, such as pharmaceutical grade media and corrosive high viscosity media.
The working principle of a dual rotor pump can be further explained as follows: under the action of a cam, two interlocked rotors suck in liquid from the inlet, pass through the cavity inside the rotor, and then discharge the liquid from the outlet. This type of pump is often used to transport high viscosity liquids in industries such as petroleum, chemical, and food. Due to the use of full rubber coating on its rotor, which has strong wear resistance, and the high-precision clearance fit between the rotor and the shell, this pump has been widely used in many engineering projects.
In addition, the double rotor pump has a high pressure head, usually a small flow rate, and uniform discharge, making it suitable for conveying liquids with high viscosity, lubricity, but without solid particles. This type of pump does not have a suction valve and a discharge valve. The energy is directly applied to the liquid in the form of static pressure on the side where the rotor in the pump body comes into contact with the liquid, and the liquid is discharged through the squeezing effect of the rotating rotor. At the same time, space is left on the other side to create low pressure, allowing the liquid to be continuously sucked in
