Description
Technical field
The utility model is widely used in carrying in the production procedure of enterprises such as oil, chemical industry, pharmacy, printing and dyeing, plating, food, environmental protection the corrosive liquids that does not contain iron filings impurity, be particularly useful for the conveying of inflammable, explosive, volatile, poisonous and precious liquid, specifically a kind of thermostable fluorine plastics magnetic centrifugal pump.
Background technique
Magnetic drive pump is to use modern magnetomechanics principle, utilizes the magnetic force coupled drive to realize a kind of new pump of the non contact transmission of moment of torsion.At present there were a lot of problems in general fluoroplastic centrifugal pump (mechanical seal) less than 3 months working life, for example: the structural design defective, have that the moving gap of string is big, sealing surface seals unstable yielding problem, and general serviceability temperature is below 70 ℃; The processing technology complexity, galloping, working life is short, and the magnetic transmission part adopts ferrite, and magnetic property is low, and moment of torsion is little, and is bulky.
In addition, drive assembly is as the pith of magnetic centrifugal pump, drive assembly in the past as shown in Figure 1: impeller 2 ' is integrated with interior magnet steel, and the endoporus of impeller 2 ' matches with porcelain tube 8 ', the entry end of impeller 2 ' is equipped with a rotating ring 7 ', and we were referred to as the impeller assembly after assembling was finished.Separation sleeve 4 ' the back side and stainless steel sleeve 5 ' assembling, main shaft 10 ' assembles and plays seal action with separation sleeve 4 ', is fixed on the stainless steel sleeve 5 '.A bearing 3 ' is installed in the bottom of main shaft 10 '.Also assemble a stationary ring 6 ' on the pump housing 1 ', support 9 ' is connected with motor, and outer magnetic 11 ' is put into and the electric machine main shaft assembling from support 9 ' one end, with bearing 3 ' and support 9 ' assembling, the impeller assembly is installed on the main shaft 10 ' again.Shown in the structural design deficiency as follows:
1. generally all be 1mm owing to the gap of impeller and separation sleeve is very little.Plastic expansion when pump uses 70 ℃ to 80 ℃ of medium temperatures, the impeller of rotation will scratch separation sleeve.
2. the pump housing and separation sleeve all are that fluoroplastic all are plastics seam location when installing, and can make plastics compressive strain when bolt is tightened.This moment, the gap of rotating ring and two rubbing surfaces of stationary ring also just was affected, and can't guarantee that impeller rotates needed axial motion in scope of design.Even shrink the original size of change naturally through regular meeting in the pump housing, separation sleeve and other working of plasticss after the processing completion.
3. main shaft is to be fixed on the supported hole of stainless steel sleeve and the pump housing.And stainless steel sleeve itself will lean on the separation sleeve working of plastics to locate exactly, so the machining error of two parts assembling back all has been reacted on main shaft and the impeller with alignment error.Add that main shaft is that F4 filling carbon fiber material is made, must not be less than 0.3mm to 0.6mm with the radial clearance of porcelain tube.So the impeller rotation time can not guarantee and concentricity requirement every total, support, outer magnetic.
4. the pump utilization of stainless steel sleeve in the running makes the magnetic induction line in magnetic field be cut, and forms the magnetic eddy current.Cause the high temperature deformation of separation sleeve to destroy.The leakage field of outer magnetic will produce the magnetic eddy current with support simultaneously, cause whole rising of temperature of pump.
5. impeller and outer magnetic all are revolving parts, and static balancing test is done in national requirements, so impeller can be along with the wearing and tearing shake of main shaft be increasing when rotating at a high speed, noise is increasing.
The fluoroplastic magnetic centrifugal pump using scope of the type is little, can not be high temperature resistant, working life that can not guarantee pump.
