Stainless steel centrifugal pump couplings are used to connect shafts in different mechanisms, mainly through rotation, so as to achieve torque transmission. Under the action of high-speed power, the centrifugal pump coupling has the functions of buffering and damping, and the centrifugal pump coupling has a better service life and work efficiency guarantee. But for ordinary people, the centrifugal pump coupling is a very unfamiliar product. For those users who want to know it, where should they start to learn about it? What is the function of the centrifugal pump coupling?

Stainless steel centrifugal pump

The role of centrifugal pump coupling:

The function of the centrifugal pump coupling is to connect the pump shaft and the motor shaft of the centrifugal pump. The centrifugal pump coupling is a mechanical part that connects the electric motor and the centrifugal pump hydraulic device. Non-sliding centrifugal pump couplings often used in the field of centrifugal pump technology can be divided into rigid centrifugal pump couplings and flexible centrifugal pump couplings. The centrifugal pump coupling is also called the "back wheel". It is a mechanical part that transmits the rotating power of the motor to the pump. The centrifugal pump coupling has two forms of rigidity and flexibility. The rigid centrifugal pump coupling is actually two ring-shaped flanges, which cannot adjust the concentricity of the pump shaft and the motor shaft. Therefore, the installation accuracy is high, and it is often used for the connection of small water pump units and portable centrifugal pump units.

Classification of centrifugal pump couplings:

There are many types of centrifugal pump couplings. According to the relative position and position changes of the two connected shafts, they can be divided into:

1. Fixed centrifugal pump coupling

It is mainly used in places where two shafts require strict alignment and no relative displacement during work. The structure is generally simple and easy to manufacture, and the instantaneous speed of the two shafts is the same. The main flange centrifugal pump couplings and sleeve centrifugal pump couplings Shafts, jacketed centrifugal pump couplings, etc.

2. Removable centrifugal pump coupling

It is mainly used where the two shafts are deviated or have relative displacement during work. According to the method of compensating displacement, it can be divided into rigid movable centrifugal pump coupling and elastic movable centrifugal pump coupling.

1) Rigid removable centrifugal pump coupling

Use the dynamic connection between the working parts of the centrifugal pump coupling to have a certain direction or several directions to compensate, such as the jaw centrifugal pump coupling (allowing axial displacement), the cross groove centrifugal pump coupling (Used to connect two shafts with small parallel displacement or angular displacement), universal centrifugal pump coupling (used in places where the two shafts have a large deflection angle or a large angular displacement in work), gear centrifugal pump Coupling (allowing comprehensive displacement), chain centrifugal pump coupling (allowing radial displacement), etc.

2) Flexible removable centrifugal pump coupling

The elastic deformation of the elastic element is used to compensate for the deflection and displacement of the two shafts. At the same time, the elastic element also has buffering and damping properties, such as serpentine spring centrifugal pump coupling, radial multilayer leaf spring centrifugal pump coupling, elastic Ring pin pin centrifugal pump coupling, nylon pin pin centrifugal pump coupling, rubber sleeve centrifugal pump coupling, etc. Some of the centrifugal pump couplings have been standardized. When choosing, you should first select the appropriate type according to the work requirements, and then calculate the torque and speed according to the diameter of the shaft, and then find the applicable model from the relevant manual, and finally make the necessary check calculations for some key parts.
