Magnetic pipeline pump that can be directly installed in the water pipe on the pump, the use of centrifugal pump, with the flange connection pipe. The internal rotation of the water rises too, the internal pressure becomes smaller due to the atmospheric pressure, the water enters the turbine part. Magnetic pump is often used to increase the water pressure in the water pressure, but also for other water cycle system. In general by the motor casing, a motor stator, rotor, sealing sleeve, water pump casing, impeller, pump cover, motor shaft, filter, end cap groove, composed of seal and graphite bearing, magnetic pump is characterized in that the sealing sleeve will be separated from the motor stator and rotor shielding, and a sealing rubber ring seal the filter in the end cover, the end cover is provided with an end cover groove, the use of graphite bearing sliding bearing, the pump impeller is made of cast iron, magnetic pump motor shell using Aluminum Alloy or cast iron casting.
Installation and commissioning of magnetic pump
(a) high temperature magnetic pump should be installed horizontally. Check the lubricating oil cooling box oil magnetic pipe pump before driving. If the oil level is too low should be added. Before opening the pump. First open cooling water loop. The inlet valve opening degree should be adjusted according to the normal operation of the pump after cooling water outlet temperature.
(two) when the suction surface is higher than the fruit axis. Before starting the valve can open the suction pipe. If the aspiration level below the pump axis. The pipeline to be equipped with bottom valve.
(three) the use of the pump should be checked before the motor is rotated to be flexible.
(four) check whether the rotation direction of the motor is in line with the same as the magnetic pump.
(five) after the motor is started, the discharge valve is slowly opened, and the pump is in the normal working condition. Before the pump stops working, close the drain valve and then cut off the power supply.
Two, the use of magnetic pipeline attention:
1, because the magnetic pump bearing cooling and lubrication is being delivered by the media, so the absolute prohibition of free rotation, and avoid to start work again in space carrying midway after blackout.
2, the transmission medium, the magnetic pump if it contains solid particles, the pump inlet to add filter: such as containing ferromagnetic particles, need to add magnetic filter.
3, pipeline pump in the use of the environment temperature should be less than 40, the motor temperature rise should not exceed 75.
4, the transmission medium and its temperature should be within the scope of the pump material (see table). The use of engineering plastic pump temperature <60, the use of metal pump temperature <100, the transmission of the pressure is not greater than 0.2MPa, the maximum working pressure 1.6Mpa, the density is not greater than 1600kg/m3, the size of the liquid is not greater than 30 x 10-6m2/s.
5, pipeline pump for the transfer of liquid for the easy precipitation crystallization of the media, the use of magnetic pipeline pump should be cleaned in a timely manner, the drain of the liquid pump.
1500, 6 hours after the pump operation, should be removed and the bearing and the end of the wear and tear of the ring, and replace the worn parts of the.
7, magnetic pump magnetic coupling with high performance permanent magnetic material, the following devices may have potential hazards, please keep the following devices with this series of pumps to keep distance.
