Background technology
At present, the complete No leakage of magnetic drive pump, is widely used in all kinds of liquid such as inflammable, explosive, poisonous, harmful, valuable
The conveying of medium.The operation principle of magnetic drive pump is that the magnetic line of force of inside and outside magnet rotor penetrates air gap and non magnetic separation sleeve reality
The contactless synchronous transmission of existing torque, during magnetic force pump operation, metal separation sleeve is in the alternating magnetic field of inside and outside magnet rotor will production
Magnetisation vortex heat, the low temperature easy vaporized medium conveyed is easy to therefore produces vaporization, and the circulation loop of pump can not utilize defeated
Magnet rotor and lubrication bearing holder (housing, cover), axle sleeve and thrust disc, ultimately result in key components and parts because of dry grinding in the liquid medium cooling sent
Damage is burnt, the magnet steel of interior magnet rotor also can be because lacking liquid cooling and loss of excitation, and it is general that magnetic drive pump is used for transporting low temperature easy vaporized medium
Had an optimistic view of all over industry is not used.
Utility model content
The purpose of this utility model, exactly easily vaporize Jie for conveying ultralow temperature there is provided one kind to solve the above problems
The magnetic drive pump of matter.
In order to achieve the above object, the utility model employs following technical scheme：Jie is easily vaporized for conveying ultralow temperature
The magnetic drive pump of matter, including the pump housing, impeller, pump shaft, bearing block, intermediate, thrust disc assembly, axle sleeve, shelves set, bearing holder (housing, cover), interior magnetic
Rotor assembly, separation sleeve, outer magnet rotor assembly, hitch, circulation pipe and gas-liquid equilibrium pipe；The pump shaft is provided with half-via,
And the bearing chamber being encircled into by original through hole and axle sleeve, shelves set, bearing holder (housing, cover).
The bearing block is provided with through hole, the bearing chamber that connection circulation pipe is encircled into axle sleeve, shelves set and bearing holder (housing, cover).
The interior magnet rotor assembly rear is provided with auxiliary blade.
The separation sleeve is provided with connection holes and gas-liquid equilibrium pipe UNICOM.
Magnetic drive pump stable and reliable operation of the present utility model, magnetic force pump discharge draws circulation pipe to bearing chamber, lubricates and cold
But axle sleeve, bearing holder (housing, cover) and thrust disc assembly friction pair, medium is by pump shaft half-via, and pressurization cycle is cold under auxiliary blade effect
Interior magnet rotor assembly and separation sleeve, couple storage tank gas phase chamber balance system pressure by external gas-liquid equilibrium pipe, are effectively ensured
The even running of magnetic drive pump, while avoiding because vaporization causes scarce liquid unlubricated and cooling phenomenon, makes the magnetic drive pump completely available
In the field of transporting low temperature easy vaporized medium.
Brief description of the drawings
Fig. 1 is overall structure diagram of the present utility model.
Embodiment
It is of the present utility model to be used to conveying the magnetic drive pump of ultralow temperature easy vaporized medium referring to Fig. 1, including the pump housing 1, impeller 2,
Pump shaft 3, bearing block 4, intermediate 5, thrust disc assembly 6, axle sleeve 7, shelves set 8, bearing holder (housing, cover) 9, interior magnet rotor assembly 10, separation sleeve
11st, outer magnet rotor assembly 12, hitch 13, circulation pipe 14 and gas-liquid equilibrium pipe 15；Half-via 31 is provided with pump shaft 3, and is led to
Cross the bearing chamber that original through hole 32 is encircled into axle sleeve, shelves set, bearing holder (housing, cover).Through hole 41 is provided with bearing block 4, even
The bearing chamber that logical circulation pipe is encircled into axle sleeve, shelves set and bearing holder (housing, cover).Auxiliary blade is provided with the interior rear of magnet rotor assembly 10
101.Provided with connection holes 111 and the UNICOM of gas-liquid equilibrium pipe 15 on separation sleeve 11.
The utility model is provided with circulation pipe 14 between the pump housing 1 and intermediate 5, by the circulation pipe 14, and magnetic drive pump can be by
The medium conveyed enters axle sleeve 7, shelves set 8 and bearing holder (housing, cover) 9 from the outlet higher-pressure region of magnetic drive pump by the through hole 41 on bearing block 4
The bearing chamber being encircled into, can make the key components and parts axle sleeve 7, bearing holder (housing, cover) 9 and thrust disc assembly 6 of magnetic drive pump obtain being conveyed Jie
The sufficient lubrication of matter.
Surrounded due to being provided with half-via 31 on pump shaft 3, and by original through hole 32 with axle sleeve 7, shelves set 8 and bearing holder (housing, cover) 9
Into bearing chamber, the highly pressurised liquid for entering bearing chamber effectively can be drained into the auxiliary at the interior rear of magnet rotor assembly 10
Blade 101 rotates at a high speed the low-pressure area of formation, and in the effect lower edge of auxiliary blade 101 between magnet rotor total 10 and separation sleeve 11
Gap accelerate circulation, interior magnet rotor assembly 10 and separation sleeve 11 are able to sufficient lubrication and cooling.
Because separation sleeve 11 is provided with connection holes 111 and the UNICOM of gas-liquid equilibrium pipe 15, the other end and quilt of gas-liquid equilibrium pipe
The gas phase chamber of pumped (conveying) medium storage tank is connected, and system pressure can be made to remain stable, it is ensured that magnetic drive pump is normally run.
The utility model open cycle hole at pump discharge, the opened hole on bearing block, by external circulation pipe by pump discharge
The highly pressurised liquid at place is communicated to bearing chamber, axle sleeve, bearing holder (housing, cover) and thrust disc assembly friction pair is able to sufficient lubrication, so that
Play a part of protecting friction pair not burn because vaporization causes to dry grind.
The utility model make use of auxiliary blade that the highly pressurised liquid for flowing through bearing chamber is carried out into pressurization cycle, make interior circulation
Liquid is in high pressure and pressurized state, it is ensured that interior circulation pressure medium is vaporized higher than saturated vapor pressure without producing, so effective
It ensure that interior magnet rotor assembly and separation sleeve are adequately cooled.
Separation sleeve flange is provided with connection holes, and external gas-liquid equilibrium pipe is connected with by the gas phase chamber of conveying wet tank,
Due to inside and outside magnet rotor assembly, rotation can produce magnetic vortex heat at a high speed, flow through separation sleeve and interior magnet rotor inner chamber will forming portion
Divide vaporizing liquid, while as sealing liquid in storage tank is increasing by conveying vacuum, external gas-liquid equilibrium pipe can be to storage tank
Gas phase chamber carries out pressure releveling, and system pressure has been effectively ensured and has kept balance, it is to avoid vacuum breaking, so as to protect pump chamber to fill
Full transported medium is without no-load running.
