The high pressure magnetic drive pump comprises a magnetic drive transmission device, a transmission shaft, a power transmission device, and a pump body. Compared with a conventional magnetic drive pump, the high pressure magnetic drive pump has the advantages of simple structure, reliable performance, high intensity, stability and safety.
Description
Technical field
The invention belongs to the liquid delivery pump technical field, in particular, belong to a kind of high-pressure magnetic pump.
Background technique
Existing conventional magnetic drive pump adopts common magnetic seal apparatus structure, and common magnetic seal comprises internal rotor body, external rotor body, separation sleeve.Separation sleeve is with the complete hermetic separation of inner and outer rotors body, and when pump turned round, medium was with the complete submergence of internal rotor body in the separation sleeve; Its inside certainly exists interior pressure; Press in this is to equate that with the pressure of pumped medium separation sleeve will well be realized seal action, just must enough sustain the interior pressure of pumped medium; The assurance separation sleeve is indeformable, and is not damaged.Because the air gap of inside and outside magnet rotor body can directly have influence on the efficient of magnetic device, so air gap cannot infinitely increase, and separation sleeve carries out cutting magnetic induction line in the pump operation process in magnetic field; Having eddy current produces; With form of heat loss, being referred to as the whirlpool usually and decreasing, the whirlpool is decreased and is directly proportional with separation sleeve thickness; So separation sleeve thickness can not be too thick, otherwise the efficient of magnetic device is also had very big influence.If the thickness of separation sleeve is too thin, its bearing capacity is also just inevitable undesirable, and this material combination property that just requires to make separation sleeve wants high; Generally all can adopt metal stainless steel or non-magnetic alloy; Under common operating mode, the intensity of separation sleeve can meet the requirements, but voltage endurance capability still has certain limitation under special operation condition; As when carrying the medium of high pressure operating mode, common magnetic seal device possibly just be difficult to realize reliable on the separation sleeve intensity.On supporting way, adopt the sliding bearing multi-point support, sliding bearing is fixed on the body of sliding bearing; The body of sliding bearing and the pump housing, link press span, separation sleeve are fastenedly connected, and this helps rotor part running rigidity, and it is little that it is beated; Vibrate for a short time, noise is little, and is little to environmetal impact.
On backwashing manner; Introduce the media fluid lubrication sliding bearing of cleaning through the flushing hole of bearing support; Take away sliding friction pair and separation sleeve whirlpool and decrease the heat that produces; Prevent that medium from raising and the demagnetization inefficacy of generation cavitation and magnetic force coupling device in separation sleeve internal cause temperature, plays the effect of lubricated cooling.Guarantee the normal safe handling of pump.Adopt impeller nut at impeller end, strengthen the Security of pump with anti-loose structure.The common magnetic drive pump pump housing adopts casting processing to form, and generally can not occur distortion or seepage at 2.5Mpa with interior, but under the high pressure operating mode, because the defective of cast member or the ultimate strength of the selection of material probably just are difficult to guarantee inadequately.Special industry field not only requires equipment will guarantee zero leakage but also more will guarantee its safety, and the conveying of particularly inflammable, explosive, poisonous, strong corrosive medium requires high tenacity, stability and the Security of equipment especially.
