Magnetic pump use and troubleshooting
1. Because the cooling and lubrication of the magnetic pump bearing is based on the medium being conveyed, it is forbidden to run at idle, and at the same time, it can avoid the no-load operation caused by the start-up after a power failure.
2. If there are solid particles in the medium to be transported, the filter inlet should be added to the pump inlet: If it contains ferromagnetic particles, a magnetic filter must be added.
3. The ambient temperature of the pump during use should be less than 40°C and the temperature rise of the motor must not exceed 75°C.
4. The medium to be conveyed and its temperature should be within the allowable range of the pump. The working temperature of the engineering plastic pump is less than 60°C, the temperature of the metal pump is less than 100°C, the auxiliary suction pressure is not more than 0.2MPa, the working pressure is 1.6MPa, the density is less than 1600kg/m3, and the particle size is not more than 30X10-6. M2/S liquid without hard particles and fibers.
5. For the medium that is easy to precipitate and crystallize when the transport liquid is used, it should be cleaned and drained in the pump after use.
6. After the magnetic pump is operated for 500 hours, the wear and idle condition of the bearing and the face ring should be checked. If the clearance between the bearing and the shaft sleeve is greater than 0.5~1mm, the impeller should be replaced by the axial direction when it is 1.5~2mm. Moving ring.
