Description
Technical field
The utility model relates to magnetic drive pump, particularly a kind of magnetic drive pump using for mechanical seal device coolant liquid external circulating system.
Background technique
Mechanical seal device (as PLAN52/53 scheme) is provided with coolant liquid external circulating system, is provided with recycle pump, for cooling liquid is circulated in coolant liquid external circulating system.
The recycle pump using in prior art mechanical seal device coolant liquid external circulating system is common gear pump or centrifugal pump, not only noise is large, and poor sealing, has leakage, when minding for poisonous and harmful substances enters, this leakage meeting impacts environment and safety.
Conventional magnetic drive pump consists of the pump housing, pump cover, main shaft, impeller, interior magnet rotor, separation sleeve, outer magnet rotor, link press span, bearing housing, impeller is arranged on the axle head of main shaft in pump housing inner chamber, separation sleeve and pump cover are sealedly and fixedly connected and make shaft seal, the interior magnet rotor being arranged on the main shaft the other end coordinates with the outer magnet rotor of separation sleeve outside in separation sleeve, in being driven by outer magnet rotor, magnet rotor and main shaft rotate, pump shaft impeller rotation work.Its complex structure, volume is large, and cost of production is high, for minding conveying.But and be not suitable for the outer circulation of mechanical seal device cooling liquid use.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, manufactures easyly, and cost is low, and usability is good, and noise is little, without leaking, and the magnetic drive pump using especially for mechanical seal device coolant liquid external circulating system,
The utility model consists of motor 1, pump cover 2, the pump housing 3, separation sleeve 4, interior magnet rotor 5, outer magnet rotor 6, centrifugal blade 7, pump cover 2 is connected by seam 23 and bolt docking with the pump housing 3, the pump housing 3 middle parts offer pump chamber 30, on the pump housing 3, symmetry offers inlet opening 32 and liquid outlet opening 33 is communicated with pump chamber 30, the symmetrical stopping table 31 that offers respectively on the pump housing 3 and pump cover 2, 21, the rotator seat 61 of outer magnet rotor 6 is by bearing 63a, 63b is rotatably installed in the stopping table 31 of offering on the pump housing 3 and pump cover 2, on 21, centrifugal blade 7 fixedly mounts on the outer ring surface of the rotator seat 61 of magnet rotor 6 outside, outer magnet rotor 6 drives centrifugal blade 7 to rotate, fixed seal connection separation sleeve 4 on the axis hole end face of the pump housing 3 and pump cover 2, interior magnet rotor 5 is fixedly mounted on motor shaft, pump cover 2 is bolted to connection with motor 1 flange, interior magnet rotor 5 coordinates the outer magnet rotor 6 of drive to rotate with outer magnet rotor 6.
The interior magnet rotor 5 that the utility model is arranged on motor shaft coordinates the outer magnet rotor 6 of drive and centrifugal blade 7 to rotate with the outer magnet rotor 6 being rotatably installed on the pump housing 3, and separation sleeve 4 will form isolation between the pump housing and motor shaft, make pump housing sealing without leakage.The cooling liquid entering in pump chamber from pump housing inlet opening 32 pumps from liquid outlet opening 33 under centrifugal blade 7 effects, to entering the ducted cooling liquid of coolant liquid external circulating system, recycles.
The utility model is simple in structure, and volume is little, and bearing capacity is high, and manufacturing is easy.Pump cover 2 docks and organizes full structural type with the pump housing 3, processes simple and convenient.Centrifugal blade 7 is directly installed on outer magnet rotor 6 pump power pump structure is simplified greatly, processes, manufactures simple and convenient.Separation sleeve 4 is directly installed on the axis hole place of the pump housing, simple in structure, easy for installation.Interior magnet rotor 5 is directly installed on motor shaft, does not block good permeability, easy for installation, also facilitates separation sleeve 4 to dispel the heat.Because medium does not enter rotor-end, the operating mode of, hazardous medium poisonous to carrying will be more safe and reliable when dismounting is keeped in repair.Also make the scope of working pump institute fed sheet of a media increase, the medium of conveying can comprise high burn into poisonous and harmful, contains solid particle-liquid, glue colloidal liquid, the liquid of gassiness etc., and also noise is little, nothing is leaked.The utility model can directly be docked on pipeline and use.
