The CQB-LG high-temperature magnetic driven centrifugal pump adopts a multiple circulation cooling structure to ensure the reliability and stability of the original power and magnetic transmission. At the same time, the use of column pin coupling reduces the noise and vibration of the pump. The detachable and column pin coupling are used simultaneously, which increases the structure of the pump and is more conducive to the heat dissipation of the pump. At the same time, it is also very convenient for users to repair or replace parts. A cooling fan blade is also designed on the outer rotor of the pump to ensure the stability of the magnetic steel. This series of pumps is suitable for transporting high-temperature media with a temperature of ≤ 300 ℃. Installation and Commissioning （1） It should be installed horizontally Before driving, check the lubricating oil level in the cooling tank If the oil level is too low, it should be replenished in a timely manner. Before starting the pump Firstly, the cooling water circuit should be opened The opening degree of the inlet valve should be adjusted according to the temperature of the cooling outlet pipe after the pump is working normally.
（2） When the suction liquid level is higher than the axis of the fruit Open the suction pipe valve before starting If the suction liquid level is lower than the pump axis line The pipeline needs to be equipped with a bottom valve.
（3） The pump should be inspected before use The motor fan blades should rotate flexibly No jamming or abnormal noise All fasteners should be tightened.
（4） Check if the rotation direction of the motor is consistent with the direction mark of the magnetic pump.
（5） After the motor is started Slowly open the discharge valve After the pump enters normal working condition Adjust the discharge valve to the desired opening. Before the pump stops working The discharge valve should be closed first Then cut off the power Close the cooling water pipe valve again. Model definition Structure diagram Precautions for use （1） The cooling and lubrication of magnetic pump bearings rely on the medium being transported So air freight transfer is absolutely prohibited At the same time, avoid spatiotemporal operation caused by restarting after a power outage during work.
（2） If the conveyed medium contains solid particles, a filter screen should be added to the pump inlet; if it contains ferromagnetic particles, a magnetic filter should be added.
（3） The conveyed medium and its temperature should be within the allowable range of the pump material. The operating temperature of the pump is less than 280 ℃, the maximum working pressure is 1.6MPa, the density is not greater than 1840kg/m3, and the viscosity is not greater than 30cm2/S, which is a liquid without hard particles and impurities. Should special working conditions be strictly in accordance with the contract agreement? Ding.
（4） For media that are prone to settling and settling during transportation, they should be cleaned promptly after use and the orange juice in the pump should be drained completely.
（5） After 1000 hours of normal operation Should bearings and end face moving rings be disassembled for inspection? Damage situation, and more? Unusable and damaged parts.
（6） The magnetic couplings inside and outside this series of pumps are made of high-performance permanent magnet materials, which may pose potential hazards to the following components. Please keep the following components at a distance from this series of pumps. Such as pacemakers, credit cards and other magnetic cards, calculators, computer disks, watches, etc. Malfunctions and troubleshooting
