High temperature magnetic drive pump is very convenient for users to repair or replace parts, in the outer rotor part of the pump is also designed to dissipate the wind blade, to ensure the stability of the magnetic steel. High temperature magnetic pump is suitable for conveying high temperature medium, temperature ≤300℃. The following magnetic pump manufacturer saiken pump industry to introduce some high temperature magnetic pump precautions. 1. No ferromagnetic impurities or particles are allowed to enter the magnetic drive and bearing friction pair. 2. After conveying the medium that is easy to crystallize or precipitate, it should be washed in time to ensure the service life of the sliding bearing. 3. When conveying the medium containing solid particles, it should be filtered at the entrance of the pump flow pipe. 1. The magnetic torque can not be designed too small. 2, should operate under the specified temperature conditions, it is strictly prohibited to exceed the medium temperature. A platinum resistance temperature sensor can be installed on the outer surface of the magnetic pump isolation sleeve to detect the temperature rise in the annular gap area, so as to alarm or stop when the temperature exceeds the limit.1. Idling is strictly prohibited. 2. It is strictly prohibited to evacuate the medium. 3. Under the condition that the outlet valve is closed, the continuous operation time of the pump shall not exceed 2min to prevent the failure of the magnetic drive due to overheating. Four, can not be used in the pressure system, because there is a certain gap in the magnetic pump chamber and the magnetic pump is used in the "static bearing", so this series of pumps can not be used in the pressure system, positive pressure and negative pressure are not feasible. 1, for the conveying liquid is easy to precipitate crystallization medium, after use should be cleaned in time, drain the liquid in the pump. 2. After the normal operation of the magnetic pump for 1000 hours, the wear of the bearing and the end moving ring should be dismantled and replaced, and the wearing parts should not be used again. 3, because the cooling and lubrication of the magnetic pump bearing is by the conveying medium, so it is prohibited to empty operation, while avoiding the time and space load operation caused by the power failure after restarting in the middle of the work. 4, the conveying medium, if contains solid particles, pump inlet to add filter, such as containing ferromagnetic particles, need to add magnetic filter. 5. The ambient temperature of the pump in use should be less than 40℃, and the temperature rise of the motor should not exceed 75℃. Above is the Saiken pump industry released the use of high temperature magnetic pump precautions, I hope to help you.
