Magnetic gear pump is a magnetic drive pump type, one of its main advantages is very good sealing, magnetic gear pump magnetic drive equipment is mainly composed of internal and external magnetic rotor and barrier sleeve components, this paper mainly introduces the magnetic gear pump isolation sleeve selection.

KCB stainless steel magnetic gear pump

The isolation sleeve in the magnetic gear pump magnetic driving equipment is the only pressure component to ensure the sealing of the magnetic pump does not leak, and it is also a static sealing isolation component between the inner and outer magnetic rotors. Isolation sleeve is mainly under the magnetic gear pump in the operation of the internal pressure, because of the high strength of the pressure, so the isolation sleeve is generally made of metal materials. Magnetic gear pump isolation, long-term work in a magnetic field to produce the serious magnetic eddy current loss effect, the effect is similar to the power effect, therefore the isolation of the conductive properties of materials used, the cross section area and speed determines the size of the eddy current effect, generally the value and efficiency, the better the greater the eddy current loss caused by it. Visible isolation sleeve in the selection of materials should try to choose those non-ferromagnetic, high resistivity materials, the commonly used materials are austenitic stainless steel, titanium alloy, Hastelloy and so on. Under the condition of 2900r/min operation of the magnetic pump, the eddy current loss of the isolation sleeve made of stainless steel can reach 15%~20%. The hastelloy alloy isolation sleeve has high resistivity and good strength, which can greatly reduce the eddy current loss. However, the high cost of this material is not conducive to wide application. In fact, compared with the metal isolation sleeve, the isolation sleeve made of non-metal can greatly reduce or even completely eliminate eddy current loss. If the working condition permits, high strength engineering plastics can be used as the material of the isolation sleeve. At present, magnetic gear pump isolation sleeve is widely used in titanium alloy, Hastelloy, 316L and other three metal materials, titanium alloy is the best cost performance, but the choice also needs to be considered according to the transport medium.

How to choose magnetic gear pump isolation sleeve small knowledge berth pump industry is introduced here, the use of magnetic gear pump users and the choice of isolation sleeve material users can pay attention to berth gear pump
