1、 Working principle of cam rotor pump

It is a positive displacement pump, and its working principle mainly includes the following steps:

1. Inhalation: The rotor inside the pump body rotates with the cam, causing the fluid at the suction port to be sucked into the pump body;

2. Compression: As the contact area increases, the rotor compresses the fluid being sucked in;

3. Discharge: The compressed fluid is forced out of an outlet with a relatively smaller volume.

Throughout the entire process, the rotation of the cam drives the rotor to rotate inside the pump chamber, and fluid is continuously sucked in and discharged, forming an uninterrupted fluid compression process. Due to the tight fit between the cam and rotor, the cam rotor pump has high sealing performance and can withstand high pressure and flow rates.

2、 Advantages of cam rotor pump

The cam rotor pump has the following advantages:

1. High efficiency: The output flow rate of the cam rotor pump is proportional to the speed, and it can withstand high pressure and flow rate, thus having high efficiency;

2. Stability: The compact pump chamber structure of the cam rotor pump reduces fluid fluctuations inside the pump body, thereby making the output flow rate of the pump body more stable;

3. Simple structure: The cam rotor pump has a simple structure, is easy to repair and maintain, and has relatively low maintenance costs.

3、 Disadvantages of cam rotor pump

The cam rotor pump also has the following disadvantages:

1. Influenced by the viscosity and leakage of the fluid: Due to the imperfect sealing between the cam and rotor, the viscosity and leakage of the fluid can affect the operating performance of the cam rotor pump;

2. Not suitable for corrosive fluids: Due to the relatively single material of the pump body of the cam rotor pump, it is not suitable for some corrosive fluids.

In summary, cam rotor pumps have certain advantages and disadvantages in that they draw liquid from the suction port into the pump chamber through the interaction between the cam and the rotor, compress the liquid through the rotation of the rotor, and finally discharge it from the outlet. In practical applications, it is necessary to choose the appropriate pump type and material according to different situations.
