Description
The present invention belongs to invention electric, mechanical field hereinafter to be referred as the separation layer compressor.Its structure characteristic is between the rotor of motor a separation layer to be arranged.
As refrigeration agent, the refrigerating efficiency height of ammonia, cheap, particularly ammonia does not damage the ozone layer as fluorine Lyons, so ammonia is very desirable refrigeration agent.But because ammonia has extremely strong corrosivity to copper, the copper winding of motor does not allow to work in the ammonia environment, therefore present ammonia refrigerating compressor can only be made opening type, and bigger closed, the semi-hermetic refrigerating compressor unit of quantity can not be made refrigeration agent with ammonia, can only use fluorine Lyons, this has caused the serious concern of the whole society.
The object of the present invention is to provide and a kind of motor rotor is contained in the hermetically sealed can, and stator coil is contained in the outer closed or semienclosed compressor of hermetically sealed can, it adopts the hermetically sealed can of band insulation layer structure, separation layer is the inwall part of stator iron core, it is again the part of hermetically sealed can, therefore can be with the stator coil design in the hermetically sealed can outside, thereby have the following advantages: refrigeration agent, refrigeration oil in (1) stator coil and the hermetically sealed can separate, not corroded by it, therefore can adopt ammonia to make refrigeration agent, substituted freon.(2) improve the stator heat dispersion, improve working life, reduce power consumption; (3) this motor needing can be used for motor corrosion-resistant chemical industry.
The present invention is called and isolates the laminar compressor, it is made up of air pump and motor two large divisions, air pump is made of driving mechanism, compression chamber, Aspirating valves and outlet valve, motor partly is made of stator and rotor, feature of the present invention is to have separation layer to separate between stator coils of motor and the rotor, separation layer has good tightness, it has double identity: the part of both having served as the inner tines of stator iron core, it is again the part of hermetically sealed can, hermetically sealed can is enclosed in the inside together with motor rotor and other mechanical motion part, becomes closed, semi-hermetic refrigerating compressor unit.And with stator every in hermetically sealed can outside.
16 is the long strip magnet case in the accompanying drawing, is made by the material of high magnetic conduction, low iron loss, and available powder metallurgy permeability magnetic material sintering forms or builds up and make with high silicon steel with the long strip silicon steel plate, and serving as the magnetic conduction bar by the tooth portion 16 of stator iron core is good scheme.15 is the magnetic gap bar, make (also more available magnetic material is to improve electromagnetic performance in the magnetic gap bar) by high magnetic resistance, big resistance, high-strength material, because stator coil is designed in the hermetically sealed can outside, some performances of compressor have so just been improved, separate as the refrigeration agent refrigeration oil in stator coil and the hermetically sealed can, not corroded by it, therefore can adopt ammonia to make refrigeration agent, substituted freon; It is convenient to change, keep in repair staor winding, the stator perfect heat-dissipating.
From electric machine structure, separation layer can be divided into two kinds of integral type and detachable types.Integral type separation layer motor does not change the stator iron core of original motor, just its groove contract is taken out, use resin material (and reinforcing filler) injection moulding or casting to fill up notch then, the tooth portion 16 that exceeds coil and the coil 14 of resin and its stator iron core are combined closely, naturally form magnetic gap bar 15, extend the separation layer (*) that resin material is made into environmental sealing loop construction among tubular separation layer (*) among Fig. 1 or Fig. 5 then, separation layer becomes as a whole with stator iron core, so there is double identity in the tooth portion of stator iron core, it is the part (can not cause the big variation of electrical properties) of former iron core, be again a component part of this airtight member of separation layer, separation layer and stator iron core are an integral body on physical arrangement.Hermetically sealed can is constructed as follows: cover 1 and electric motor end cap 7 form sealing under fastening piece and sealing gasket cooperate, (or cover 1, end cap 7, casing 8 are cast into one); Among Fig. 1, seal ring 7A, 7B and 13A, 13B that front and back ends covers entangle separation layer, stick with glue body 17 sealings between the running-on, and rear end cover is the closing cap of no axis hole.So the formation hermetically sealed can will have the parts (comprising that rotor is with the air pump part) of mechanical motion to seal.Among Fig. 5, front and rear cover and motor casing 8 constitute seal, and whole motor housing (comprising the terminal box part) has become a seal, stator and rotor all to be enclosed in the inside, but stator coil is got up by the separation layer environmental sealing, can not corroded by external agency.
Detachable type separation layer and stator coil and corresponding iron core partly are discerptible.Tooth portion 16 with former stator iron core removes earlier, makes magnetic conduction bar 16 according to the shape and size of the tooth portion that removes then, with resin material (and reinforcing filler) injection moulding or casting the magnetic conduction bar is processed into the separation layer of Fig. 4 shape by mould.Separation layer plays double effect: the first, and it is the part of hermetically sealed can; The second, though its magnetic conduction bar is to be divided into two bodies with stator iron core physically, on electromagnetic performance, constituted an integral body.It is convenient that this structure changes, keeps in repair coil.
