Precautions for installation of CQB heavy magnetic pump

（1） The magnetic pump shall be installed horizontally rather than vertically. The pump body shall not bear the weight of the pipeline. For special occasions requiring vertical installation, the motor must face upward

（2） When the suction liquid level is higher than the pump axis line, open the suction pipe valve before starting. If the suction liquid level is lower than the pump axis line, the pipe shall be equipped with a bottom valve

（3） The pump shall be checked before use. The fan blade of the motor shall rotate flexibly without jamming and abnormal sound, and all fasteners shall be fastened

（4） Check whether the rotation direction of the motor is consistent with the rotation mark of the magnetic pump.

（5） After the motor is started, slowly open the discharge valve. After the pump enters the normal working state, adjust the discharge valve to the required opening.

（6） Before the pump stops working, close the discharge valve first, and then cut off the power supply.

Precautions for CQB heavy duty magnetic pump:

（1） Since the cooling and lubrication of yesin magnetic pump bearings depend on the transported medium, idling is prohibited, and space-time idling caused by restart after power failure during operation is avoided

（2） If the conveyed medium contains solid particles, a filter screen shall be added at the pump inlet; if it contains ferromagnetic particles, a magnetic filter shall be added

（3） The ambient temperature of the pump in use shall be less than 40 ℃, and the temperature rise of the motor shall not exceed 75 ℃

（4） The medium to be transported and its temperature shall be within the allowable range of pump materials. The service temperature of metal pump shall be less than 100 ℃, the conveying suction pressure shall not be greater than 0.2MPa, the larger working pressure shall be 1.6Mpa, the density shall not be greater than 1600kg / m2, and the viscosity shall not be greater than 30 ℃ × L0-6m2 / s liquid without hard particles and fibers

（5） If the conveying liquid is easy to precipitate and crystallize, it shall be cleaned in time after use to drain the accumulated liquid in the pump

（6） After 1000 hours of normal operation of the magnetic pump, the wear of the bearing and end face moving ring shall be disassembled and inspected, and the vulnerable parts that are not suitable for reuse shall be replaced.
