Why Can't Magnetic Pump Run At a High Speed?

Why Can’t Magnetic Pump Run At a High Speed? What Are The Hazards Of High Speed Of Magnetic Pump?

In the application process of magnetic pumps, high rotation speed is the cause of many common faults. Therefore, as a pump user, it is important to know that magnetic pumps cannot rotate at high speeds. Today, let me analyze for you the dangers of the magnetic pump not being able to rotate at high speeds. See below for details.
 
1. The magnetic pump cannot rotate at high speeds because the magnetic cylinder of the magnetic pump is cooled by substances. If the rotation speed is high, the wheels of the magnetic cylinder will lock.
 
2. The rolling bearings of the magnetic pump motor rotor are mostly made of carbide cutting material and are lubricated by substances. The pump cannot be started without lubrication.
 
3. After the magnetic pump rotates at a high speed, there is no material to cool the pump, which may cause the diaphragm sleeve to burn through directly.
 
4. The key components of the magnetic pump are the external magnet and the internal magnet. If the rotation speed is high, the key components will be demagnetized at high temperature, and the performance index of the magnetic pump after demagnetization will be greatly reduced.
 
Through the above content sharing, it can be concluded that the magnetic pump cannot rotate at high speed, otherwise it will affect the normal use of the pump. In order to effectively improve the service life of the magnetic pump, you may wish to have an in-depth understanding of the basic knowledge about the use of magnetic pumps.


 
1. Installation: Choose the installation position reasonably according to the size of the pump. It should not be too high to affect the normal suction range of the pump. Pay attention to reserve a certain amount of heat dissipation space around the motor, and ensure that the environment is clean to prevent foreign objects from entering the motor. After completing the installation work, check the tightness of each connection.

2. Check before starting: Use the tool plate to pump several times to confirm that there is no jamming during transportation. The fan impeller should rotate flexibly. You can test run it for a few seconds to confirm that the steering is correct.

3. Start-up operation: If the water level of the pumped liquid is higher than the centerline of the pump axis during operation, it is necessary to open the suction pipe valve before starting. If the pumped liquid level is lower than the centerline of the pump axis, a bottom valve is configured for the pipeline.

4. Parameter optimization: According to the pump type marking and motor power, reasonably adjust the operating parameters and keep monitoring the parameters. If there are fluctuations in flow, pressure, etc., stop the machine in time to check the cause.

5. After starting the motor: Be careful not to adjust the flow rate quickly and drastically. The discharge valve should be opened slowly after starting the machine. After the pump enters the normal working state, the discharge valve should be opened as needed.

6. When stopping the pump: first close the discharge valve, then close the suction pipe valve.

Any abnormality during the use of the magnetic pump should not be ignored, and the cause should be found out and further solved according to the fault phenomenon.
