1. Component structure analysis

The structure of the magnetic pump and the components of the magnetic pump: the magnetic pump is composed of the three parts: the pump, the magnetic drive and the motor, and the magnetic drive consists of an external magnetic cylinder, inner magnetic cylinder and non -magnetic isolation sleeve.

The structure of the magnetic pump is similar. It depends on who the magnetic properties of the magnetic block are maintained.

At present, there are more magnetic materials for magnetic pumps. The commonly used are Alnico, iron oxygen, and rare permanent magnetic shirt diamond SMCO5 (referred to as 1: 5), SM (CO, CU, FE, ZR) 7.4 (referred to as shorts 2:17), ND -FE -B, etc.

Among them, rare earth permanent magnet materials are the most preferred. The most powerful is the 钕 iron boron ND -FE -B, which has a maximum magnetic energy accumulation of up to 28x104t · A / m or more. Nechara's stubborn force exceeds 1120ka / m, which is well -favored. However, the working temperature cannot exceed the high temperature conditions of 120 ° C, and the magnetic energy accumulation of 7 (CO, CU, Fe, ZR) 7.4 is selected at high temperature conditions.

1. The shell part: consisting of the pump body, pump cover, etc., which to withstand the entire work pressure of the pump; the hydraulic form of the pump leaf wheel is in line with the API685 standard. It is the main representation part of the hydraulic performance of the magnetic pump. As a result, the mechanical energy of the original motivation is converted into liquid energy.

2. Rotor part: divided into rotating parts installed on the pump shaft and rotating parts installed on the drive shaft. The pump shaft is an important part that carries the impeller and internal rotor and the torque.

The rotating part installed on the pump shaft consists of the rotor part of the impeller, bearing, thrust ring component, internal magnetic rotor component, etc., and the pump shaft itself.

The rotating parts installed on the driver shaft consists of an external magnetic rotor component, rolling bearing, driving shaft sleeve, etc. The driving shaft itself is composed of a rotor part of the air.

3. Connection part: Static connecting parts composed of connecting supporting support from the connection rack, bearing box. Sliding bearing, shaft sleeve, and stop plate: It is the support and positioning parts of the pump rotor parts.

4. The transmission part: The pump and the original motivation are connected to the component component of the linked shaft. During the maintenance, the magnetic pump can be maintained by unloading the intermediate membrane of the coupling.
