(A) The magnetic pump should be installed horizontally, should not be erected, plastic pump body shall not withstand the weight of the pipeline, for special requirements vertical installation of the occasion, the motor must be upward. (B) When the suction level is higher than the pump, the heart line, before starting to open the suction pipe valve can be, if the pump surface below the pump line, the pipeline should be equipped with the end of the valve. (C) The pump should be checked before use, the motor blades to be flexible rotation, no stuck and abnormal sound, the fasteners to be tightened. (D) check the motor rotation direction and magnetic pump steering mark the same. (E) After the motor starts, slowly open the discharge valve , to be pump into the normal working condition, and then adjust the discharge valve to the desired opening. (F) pump stop working, you should close the discharge valve, and then cut off the power. Seven, the use of matters needing attention (a) due to pump bearing cooling and lubrication is by the transmission of the shield, it is absolutely forbidden air-to-run, while avoiding the power outage after the restart caused by the time-space operation. (B) is transported medium, if it contains solid particles, the pump inlet to add filter: If containing ferromagnetic particles, the need to add magnetic filters. (C) The pump should be used in the ambient temperature should be less than 40 ℃, the motor temperature should not exceed 75 ℃. (D) sent by the elm medium should pump within the allowable range. Fluorine plastic pump temperature can not be lower than minus 30 ℃ maximum can not exceed 100 ℃. Conveying suction liquid pressure not greater than 0.2MPa, the maximum working Zhuang force 1.6MPa, the density is not greater than 1600Kg / m3, the viscosity is not greater than 30 X10-6m? / S without hard particles and fibers. (E) for the transport fluid is easy to sediment and easy to use media, after use should be promptly cleaned, drain the pump effusion. (Vi) 1000 hours after the normal operation of the magnetic pump should be demolished inspection bearing and face ring wear and tear, and replace the consumable parts should not be reused. Eight, failure and troubleshooting
