Matters needing attention in self suction magnetic pump
Prevent particles from entering
(1) ferromagnetic impurities and particles are not allowed to enter the magnetic transmission and bearing friction pairs. (2) After conveying the medium which is easy to crystallize or precipitate, it should be flushed in time (after stopping the pump, water should be poured into the pump chamber, and discharged clean after running for 1 minute), so as to ensure the service life of the sliding bearing. (3) when conveying medium containing solid particles, it should be filtered at the inlet of the pump pipe.High Pumping Speedwith Ultimate Pressure 160 Mbar
2. prevent demagnetization.
(1) the magnetic moment can not be designed too small. (2) it should be operated under prescribed temperature conditions, and the temperature of medium should be strictly prohibited. The platinum resistance temperature sensor can be installed on the outer surface of the isolation sleeve of the magnetic pump to detect the temperature rise in the annulus area, so as to alarm or stop when the temperature exceeds the limit.
3. prevent dry friction
(1) no idling is strictly prohibited. (2) it is strictly prohibited to evacuate the medium. (3) When the exit valve is closed, the continuous running time of the pump shall not exceed 2 minutes to prevent the magnetic drive from overheating and failure. 3. can not be used in systems with pressure.
Because of the existence of a certain system in the cavity of the magnetic pump and the use of "static bearings" in the magnetic pump, the series of pumps must not be used in the pressurized system. Positive and negative pressure are not feasible.High Pressure Double Stage Oil Rotary Vane Vacuum Pump
(1) Because the cooling and lubrication of magnetic pump bearings depend on the conveyed medium, it is absolutely forbidden to operate empty, and at the same time, it is avoided to operate in time and space when the power is cut off in the middle of the work and restart.
(2) In the medium being transported, if solid particles are contained, a filter shall be added to the inlet of the pump: if ferromagnetic particles are contained, a magnetic filter shall be added.
(three) the ambient temperature of the pump should be less than 40 C, and the temperature rise of the motor must not exceed 75 C.
(four) the transported medium and its temperature should be within the allowable range of pump materials. The service temperature of engineering plastic pump is < 60 C, the service temperature of metal pump is < 100 C, the conveying suction pressure is not more than 0.2 MPa, the maximum working pressure is 1.6 MPa, the density is not more than 1600 Kg/m3, and the viscosity is not more than 30X10-6m2/S liquid without hard particles and fibers.
(5) For the conveying fluid, which is easy to precipitate and crystallize, it should be cleaned in time after use, and the liquid accumulated in the pump should be discharged.
(6) After 1000 hours of normal operation of the magnetic pump, the wear of the bearing and the end moving ring should be disassembled and inspected, and the vulnerable parts that are not suitable for reuse should be replaced.
