A body comprises a pump body, a bottom plate for fixing the pump body and a stator connected with the pump body. The internal circulation type self-priming shield pump is characterized in that a sealing end cover is arranged at the tail of the stator; a rotor is arranged in the stator; a rotating shaft is fixed in the rotor; one end of the rotating shaft is connected with an impeller of the pump body, and the other end of the rotating shaft is connected with a bearing at the tail; and a liquid passing hole is formed in the center of the rotating shaft. The internal circulation type self-priming shield pump has the beneficial effects that design is novel, and the structure is simple; an internal circulation runner is arranged to replace an original external runner, and the situation that collisions and breakage happen to the external runner during actual application is avoided; and the internal circulation type self-priming shield pump is convenient to use, remarkable in effect, stable, safe, convenient to operate and practical.
Description
Technical field
The present invention relates to pump valve work technical field, be specifically related to a kind of inner circulation type self-priming canned motor pump.
Background technology
Canned motor pump is by shielded motor and pump group all-in-one-piece no-leakage pump, mainly by the pump housing, impeller, stator, rotor,
The parts such as front and back bearings and thrust disc form.Stator and rotor get up with the isolation of non magnetic corrosion-resistant thin-wall sleeve respectively, rotor
Supported by front and back bearings and be immersed in pumped (conveying) medium, because preventing the outside of transported medium without the movable sealing of any pattern
Leakage.In general, canned motor pump is centrifugal unprssurized pump.The absolute No leakage of canned motor pump, in pump under negative pressure condition, extraneous gas
Body will not be inhaled into, and is particularly well-suited to vacuum system and runs；It is applicable to high pressure, high-melting-point, high and low temperature medium simultaneously.Canned motor pump
Compact conformation, volume is little, lightweight；Relatively low without cooling fan, noise, range is wide, and operating is reliable, is provided that one relatively
Good working environment.
Self-priming canned motor pump is applicable to extraction liquid from container, is characterized in that the suction line that acts on of the inner pump housing does not fills
During full liquid, pump can raise liquid by Automatic-bleeding function, and former self-suction type canned motor pump is provided with circulation pipe in the side of pump, but this
Circulation pipe easily bends because of collision in site of deployment and even damages, and directly results in the pump housing and breaks down.
Summary of the invention
The technical problem to be solved is to provide a kind of simple in construction, safe ready, follows in preventing collision
Ring-like self-priming canned motor pump.
The technical problem to be solved realizes by the following technical solutions:
A kind of inner circulation type self-priming canned motor pump, main body includes a pump housing, the fixing base plate of the pump housing and determining of connecting with the pump housing
Son, it is characterised in that: described stator afterbody is provided with the end cap of a sealing, and described stator interior is provided with a rotor, institute
Being fixed with a rotating shaft in the rotor stated, described rotating shaft one end is connected with pump housing impeller, and the other end is connected with the bearing of afterbody, institute
The spindle central stated is provided with a liquid pass hole.
It is little compared with being positioned at bearing one end diameter that described liquid pass hole is positioned at impeller one end, is gradually reduced the diameter of liquid pass hole, can
To increase the pressure of internal liquid, the high pressure facilitating internal liquid flows out.
Described end cap is positioned at the position of roller end and is provided with a concave hole, it is simple to the most without hindrance stream of internal liquid
Dynamic, more fast.
The present invention is in use: time liquid flows to stator afterbody by gap between rotor and stator, directly pass through
The liquid pass hole being positioned at spindle central flows back at impeller, completes circulation, efficient and convenient.
The invention has the beneficial effects as follows: the present invention is novel in design, simple in construction, by arranging built-in circulatory flow, replace
Original external flow channel, it is to avoid cause external flow passage collision fracture occur when reality is applied, easy to use, effect is notable, flat
Steady safety, convenient and practical.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
As it is shown in figure 1, a kind of inner circulation type self-priming canned motor pump, main body includes a pump housing 1, the base plate 2 of the fixing pump housing 1 and with
The stator 3 that the pump housing 1 connects, stator 3 afterbody is provided with the end cap 4 of a sealing, and stator 3 is internally provided with a rotor 5, in rotor 5
Being fixed with a rotating shaft 6, rotating shaft 6 one end is connected with the pump housing 1 impeller 7, and the other end is connected with the bearing 8 of afterbody, and rotating shaft 6 is centrally disposed
Having a liquid pass hole 9, after so arranging, liquid is by, time between rotor 5 and stator 3, gap flows to stator 3 afterbody, directly leading to
Crossing and be positioned at the liquid pass hole 9 at rotating shaft 6 center and flow back at impeller 7, complete circulation, efficient and convenient, liquid pass hole 9 is positioned at impeller 7 one end
Compared with being positioned at, bearing 8 one end diameter is little, is gradually reduced the diameter of liquid pass hole 9, can increase the pressure of internal liquid, facilitate inside
The high pressure of liquid flows out, and end cap 4 is positioned at the position of rotating shaft 6 end and is provided with a concave hole 10, it is simple to the abundant nothing of internal liquid
The flowing of resistance, more fast.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, without departing from the spirit and scope of the present invention, the present invention also has various changes and modifications, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
