Description
Technical field:
The utility model relates to a kind of magnetic drive pump, specifically a kind of corrosion resistant magnetic drive pump that contains granule medium of carrying.
Background technique:
Magnetic drive pump in the market mainly contains two kinds, and a kind of is the metal magnetic drive pump, and another kind is non-metal magnetic drive pump.The biggest advantage of magnetic drive pump does not have leakage exactly, if contain some particles in the fed sheet of a media, the metal magnetic drive pump is available, but just inapplicable for nonmetal magnetic drive pump.And for industries such as the chemical industry of the nonmetal magnetic drive pump of a large amount of uses, medicine, electronics, the operating mode that contains certain granules in the medium of conveying is very common.Nonmetal magnetic drive pump can not carry the main cause that contains granule medium just to be: the performance of nonmetallic material that nonmetal magnetic drive pump adopts, and the structural design of anti-particle obstruction.Therefore, need a kind of decay resistance of development widely, can contain the nonmetal magnetic drive pump of (non magnetic) particle on a small quantity in the fed sheet of a media again simultaneously.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of corrosion resistant magnetic drive pump that contains granule medium of carrying, and this magnetic drive pump decay resistance is extensive, can be used for carrying the operating mode that contains the small quantities of particles medium simultaneously.
The utility model technical solution problem adopts following technological scheme:
A kind of corrosion resistant magnetic drive pump that contains granule medium of carrying, comprise the pump housing and the impeller shaft that is positioned at pump housing inner chamber, front end at impeller shaft is provided with impeller, periphery is provided with the magnetic shaft coupling that connects firmly with motor output shaft in the rear end of impeller shaft, be provided with separation sleeve between described magnetic shaft coupling and the described impeller shaft, be provided with impeller bearing between the front end of described impeller and described impeller shaft, be provided with the separation sleeve bearing between the rear end of described separation sleeve and described impeller shaft, the front end end face of described impeller is step-like and is connected with impeller port ring, the front end inner chamber of the described pump housing is step-like and is connected with pump housing choma, and described impeller port ring and the described pump housing choma end face hard friction in opposite directions contact.
Structural feature of the present utility model also is:
The end face in opposite directions of described impeller port ring and described pump housing choma constitutes grinding pair, the end face in opposite directions of described separation sleeve bearing and described impeller bearing constitutes grinding pair, the inner peripheral surface of described impeller bearing and the outer circumferential face of described impeller shaft constitute grinding pair, described each to grinding the secondary hard friction contact of adopting.
The excircle of described impeller shaft is axially arranged with half slot along it, and described half slot is set to four, and four half slots are arranged along the circumferential five equilibrium of described impeller shaft.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
All of the utility model magnetic drive pump are hard to hard friction mode to grinding secondary employing, and the material of selecting for use comprises silicon carbide, aluminium oxide, cemented carbide etc.In common nonmetal magnetic drive pump, commonly used is soft to hard mode to grinding pair, this kind mode minimum of wearing and tearing, in case but particle enters behind the flour milling, and to sharply wearing and tearing of flour milling, cause pump to damage.And firmly can block particle well and enter grinding pair hard, so also just guaranteed the stable operation of magnetic drive pump.
Design the chute of crossing of overcurrent media particle on the inner cycle channel of magnetic drive pump, the half slot to design some on the bull ring face of impeller port ring and pump housing choma also designs four half slots on the peripheral direction of impeller shaft.But the pure medium lubricate that in these half slots, passes through, take away the fricative each other heat of associated components, play cooling action, contained particle also can pass through flour milling smoothly along these half slots in the fed sheet of a media simultaneously, directly enter pump chamber, pipeline, the inner cycle channel that is unlikely to block pumps causes pump stall, axial force uneven and damage.
All flow passage components that contact with fed sheet of a media all adopt corrosion resistant, the good nonmetallic material manufacturing of wear-resisting property.Comprise teflon, the fluoroplastic that add the enhancing carbon fiber, Fluoroine-containing plastic alloy etc.On the basis of existing resistant material, add high-abrasive material such as carbon fiber etc., can improve the wear-resisting property of material, make particle in the fed sheet of a media the time, the wearing and tearing of chamber wall are reduced by pump chamber.
The utility model adopts fixed axle structure.The magnetic drive pump of revolute axes configuration at the two ends of axle pair flour milling is arranged simultaneously, and stationary axle only has pair flour milling at the intermediate section of axle, for reducing particle to influence to flour milling, should reduce as much as possible flour milling, therefore such structure is beneficial to carry and contains granule medium, prolongs the working life of pump.
