What is the function of the centrifugal pump coupling?

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

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 component that connects the motor to the hydraulic device of the centrifugal pump. Non-sliding centrifugal pump coupling is commonly used in the field of centrifugal pump technology, which can be divided into rigid centrifugal pump coupling and flexible centrifugal pump coupling. Centrifugal pump coupling is also called “rear wheel”. It is the mechanical component that transfers the rotating power of the motor to the pump. The centrifugal pump coupling has two forms of rigidity and flexibility. Rigid centrifugal pump coupling is actually two ring flange, can not adjust the pump shaft and motor shaft concentricity. Therefore, the installation precision is high, and it is often used for the connection of small pump units and portable centrifugal pump units.

Classification of centrifugal pump coupling:

There are many types of centrifugal pump couplings. According to the relative position and position change of the two connecting axes, it can be divided into:

1. Fixed centrifugal pump coupling
It is mainly used in the place where the two axes are strictly aligned and there is no relative displacement when working. 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 coupling, sleeve centrifugal pump coupling, jacket centrifugal pump coupling and so on.

2. Detachable centrifugal pump coupling
It is mainly used when the two axes have deviation or relative displacement. According to the method of displacement compensation can be divided into rigid movable centrifugal pump coupling and elastic movable centrifugal pump coupling.

1) Rigid detachable centrifugal pump coupling
The dynamic connection between the working parts of the centrifugal pump coupling has a certain direction or several directions to compensate, Such as jaw type centrifugal pump coupling (allow axial displacement), cross groove type centrifugal pump coupling (used to connect the two axes with small parallel displacement or angular displacement), universal centrifugal pump coupling (used in the work of two axes with large deflection or angular displacement), gear centrifugal pump coupling (allow comprehensive displacement), chain type centrifugal pump coupling (allow radial displacement), etc.

2) Flexible detachable centrifugal pump coupling
The elastic deformation of the elastic element is used to compensate the deflection and displacement of the two axes. At the same time, the elastic element also has the buffering and damping performance, such as snake spring centrifugal pump coupling, radial multilayer leaf spring centrifugal pump coupling, elastic ring pin centrifugal pump coupling, nylon pin centrifugal pump coupling, rubber sleeve centrifugal pump coupling. Some centrifugal pump couplings have been standardized. In the selection, first of all, according to the work requirements to choose the appropriate model, and then calculate the torque and speed according to the diameter of the shaft, and then from the relevant manual to find the applicable model, finally some key components for the necessary check calculation.
