Structural design of CQB Ordinary Magnetic Pump: the key to ensuring safety and reliability

1. Innovative design of magnetic coupler
The magnetic coupler is the core component of CQB Ordinary Magnetic Pump. It realizes the power transmission between the motor and the pump body and maintains complete isolation between the two. This design avoids the leakage problem caused by friction, wear or aging at the shaft seal of the traditional pump, thereby improving the safety and reliability of the pump.

The magnetic coupler usually consists of two inner and outer magnetic rotors. The inner magnetic rotor is connected to the motor shaft, and the outer magnetic rotor is connected to the pump shaft. When the motor starts, the magnetic field generated by the rotation of the inner magnetic rotor is transmitted to the outer magnetic rotor through the air gap, thereby driving the pump shaft to rotate. This design not only eliminates the risk of leakage at the shaft seal, but also reduces the heat and wear caused by friction, extending the service life of the equipment.

In order to further improve the performance of the magnetic coupler, designers usually use high-performance permanent magnetic materials, such as neodymium iron boron. These materials have strong magnetic force and high temperature resistance, which can ensure the stability and reliability of magnetic transmission. The air gap of the magnetic coupling also needs to be precisely controlled to ensure that the efficiency of magnetic force transmission is maximized.

2. Advantages of the shaft sealless design
Another major feature of the CQB magnetic pump is the shaft sealless design. Traditional pumps usually require seals at the shaft seal to prevent liquid leakage. The shaft seal is often the main source of pump leakage, which not only affects the performance of the pump, but also may pollute the environment.

The shaft sealless design achieves complete isolation between the motor and the pump body through the magnetic coupling, thereby eliminating the risk of leakage at the shaft seal. This design not only improves the safety and reliability of the pump, but also simplifies the maintenance process of the equipment. Since there is no need to replace the shaft seal regularly, the maintenance cost and time of the equipment are reduced.

3. Optimized design of flow-through components
The flow-through components are the components in the CQB magnetic pump that directly contact the medium, including the pump body, impeller and guide vanes. The design of these components is crucial to the performance and reliability of the pump.

In the design of the pump body, a streamlined structure is usually used to reduce the resistance of the fluid and improve the head and efficiency of the pump. The material of the pump body also needs to be selected according to the properties of the medium to ensure its corrosion resistance and wear resistance.

The impeller is one of the core components of the pump, and its design directly affects the pump head, flow rate and efficiency. In order to optimize the performance of the impeller, designers usually use advanced fluid dynamics software for simulation analysis to determine the optimal impeller shape and number of blades. The material of the impeller also needs to be selected according to the corrosiveness of the medium to ensure its long-term stable operation.

The guide vane is used to guide the fluid from the impeller outlet to the pump outlet, reduce the vortex and turbulence of the fluid, and improve the efficiency and stability of the pump. The design of the guide vane also needs to consider the properties and flow requirements of the medium to ensure its optimal diversion effect.

4. Design of safety protection measures
In order to ensure the safe operation of the CQB magnetic pump, the designer also needs to consider a series of safety protection measures in the structure.

Temperature sensors and pressure sensors are usually required on the pump body to monitor the temperature and pressure of the pump body in real time. When the temperature or pressure exceeds the set value, the sensor will send an alarm signal and automatically shut down to prevent equipment damage or safety accidents.

In order to prevent the magnetic coupling from being damaged due to overload, the designer also needs to set an overload protection device on the motor. When the load of the motor exceeds its rated value, the overload protection device will automatically cut off the power supply to protect the magnetic coupling and the motor from damage.

In order to ensure the safety of the operator, necessary protective devices and warning signs are also required on the pump body. Valves and filters are set at the inlet and outlet of the pump to prevent impurities in the medium from damaging the pump; warning signs are set on the pump body to remind operators to pay attention to safety matters and operating specifications.
