Magnetic centrifugal pump delivery

The drive machine drives the pump's outer magnetic rotor through the magnetic field and the inner magnetic rotor is connected and drive the impeller rotation, when the pump is filled with liquid, the impeller in the drive machine is driven by high-speed rotation, in the rotation process on one side constantly inhaled medium (liquid), and on the other side will constantly absorb the medium (liquid) excluded, the vane drive the liquid rotation, so continuous work, the liquid in the role of pressure energy and velocity energy, resulting in the commercial heart force. Under the action of high center force, the liquid along the vane flow channel from the center to the surrounding thrown out, after the pump body (pump casing) sent to the discharge pipe, was transported to the workplace.

Magnetic drive centrifugal pump liquid circulation system

Magnetic drive centrifugal pump inner magnetic rotor and outer magnetic rotor ask with isolation sleeve, isolation high sleeve, suspension, pump cover, and pump body are connected together by bolts, forming a closed sealing cavity by static capacity sealing gasket, closing the main shaft and inner magnetic rotor in the ceiling cavity, thus ensuring zero leakage of the medium. The isolation sleeve is rotating relative to the inner and outer magnetic rotor, which is equivalent to a metal conductor cutting magnetic lines of force in a magnetic field, which will generate current, which is reflected in the form of heat, which is often referred to as magnetic eddy current heat. Magnetic eddy current heat can lead to the magnetic drive high heart soft within the sliding bearing, thrust bearing, and other parts burned, more serious lead to the demagnetization of the inner magnet. In response to the above problems pump manufacturers are mostly in the dish cover (high-pressure end) open hole, through the hole reflux medium to the inner magnetic rotor cooling, cooling medium through the pump shaft in the hole country to the pump population.

Magnetic drive high centrifugal pump liquid circulation role

The magnetic drive centrifugal system of the high sleeve and sliding bearings need to be cooled and lubricated. The cooling and lubricating liquid is the medium liquid conveyed, which is formed according to the special construction design of the magnetic pump itself. Cooling and lubrication need a cooling, lubrication system, the system can be a continuous high sleeve and sliding shaft to remove the heat generated, and provide sufficient lubrication to the slide bearing, to bring a good cooling environment for the isolation sleeve. This fluid in the flow process plays a cooling, lubricating role for the bearing and the isolation sleeve.

The flow of this fluid plays a role in cooling and lubricating the bearings and the isolation sleeve.

Magnetic drive centrifugal pump design of the cooling circulation route

The magnetic drive centrifugal pump is lubricated by its own transported medium, mainly to the sliding bearing, sleeve, and thrust disc for cooling and lubrication. Generally use the pressure between the impeller outlet and impeller inlet old to achieve the cooling and lubrication of the acid force system, from the impeller outlet of the high-pressure area to lead a part of the media, through the pump cover inlet, so as to cool and lubricate the sliding bearing and isolation sleeve.

Taicang magnetic pump Co., Ltd. was born in 1979. It cooperated with Shanghai Chemical Design Institute to form a unique core research project with magnetic drive pump, and achieved great success. It has become the professional company in China to comprehensively design and produce magnetic drive pump. Today, Taicang magnetic pump Co., Ltd. has become a leading manufacturer of magnetic drive pumps in China, with many patents and 12 utility model patents.
