Abstract
A vertical shield pump belongs to the pump field and overcomes the mounting defect of the current complex shield pump structure by providing a vertical shield pump with simple structure and convenient mounting. The utility model comprises a rotor, a stator, an impeller, a shaft, a face plate, and an upper balancing bearing seat and a lower balancing bearing seat; wherein the impeller wheel is arranged at the bottom of the shaft, and the lower balancing bearing seat is arranged above the impeller, while the face plate is arranged outside of the lower balancing bearing seat; and the rotor is positioned in the middle part of the shaft, and the stator is sleeved on the rotor, while the upper balancing bearing seat is positioned at the upper end of the shaft and sleeved outside of the shaft. The utility model, under the precondition of ensuring and optimizing the function, simplifies the structure and strengths the degree of axial direction dynamic balance, thus improving the service life and reliable operation as well as convenient mounting.
Description
Technical field
The utility model relates to a kind of vertical shield pump, belongs to pump class field.
Background technique
Canned motorpump mainly is made of pump case and shield electric machine, impeller in the pump case is coaxial with shield electric machine, like this, in use there is not leakage, effectively avoid polluting, be widely used in refrigeration, air-conditioning, medicine, chemical industry, fields such as oil, canned motorpump produces axial force owing to correcting pressure before and after the impeller is uneven in operation process, bearing is worn and torn easily, in the prior art for addressing this problem, taked multiple different technological scheme, as publication number is CN2546655, and open day is the Chinese patent of 2003.04.23, discloses a kind of canned motorpump, particularly a kind of tandem canned motorpump belongs to a kind of no-leakage pump.It comprises shield electric machine 1, one end of the pump shaft 7 in the shield electric machine 1 stretches in the pump case that joins with shield electric machine 1 one sides and impeller is housed, it is characterized in that: the other end of the pump shaft 7 in the described shield electric machine 1 stretches in the pump case that the opposite side with shield electric machine 1 joins and impeller is housed, the entrance and exit of pump is located at the both sides of shield electric machine 1 respectively, and pump shaft 7 is provided with intercommunicating pore 11.Have that progression is many, lift is high, the stressed symmetry of pump shaft, advantage such as applied widely.But this pumps in series complex structure is installed trouble.
The Chinese patent of notification number CN2589706 day for announcing 2003.12.03, it is to cover in the balance end that has canned motorpump now end face sealing ring is set, one gap is arranged between the end face of end face sealing ring and the back shroud of impeller, make the interior outside of end face sealing ring constitute interconnected relief chamber and pressure regulating cavity.When canned motorpump was worked, rotor assembly can be in the dynamic suspension state in a certain position.Advantage is to realize axial force transient equiliblium automatically, makes canned motorpump adapt to various media, operating mode, has improved the operational reliability of bearing working life and canned motorpump.The problem that this pump also has complex structure to be not easy to install.
The model utility content
In order to overcome existing shield pump structure complexity, be unfavorable for the deficiency of installing, the purpose of this utility model is: provide a kind of simple in structure, the vertical shield pump of being convenient to install.
The technological scheme that its technical problem that solves the utility model adopts is as follows: canned motorpump: comprise rotor, stator, impeller, axle, floral disc, go up trunnion shaft bearing, following trunnion shaft bearing, described impeller is located at the bottom of axle, following equalizer bearing seat is positioned at the impeller top, floral disc is enclosed within down outside the trunnion shaft bearing, rotor is positioned at the middle part of axle, stator is enclosed within outside the rotor, and last equalizer bearing seat is positioned at the upper end of axle, is nested in outside the axle.
Compared with prior art, the beneficial effects of the utility model are:
The utility model has been simplified the structure of vertical shield pump under the prerequisite of the function of assurance and optimization vertical shield pump, strengthened the degree of the axial transient equiliblium of vertical shield pump, improved the working life and the canned motorpump reliability of operation of bearing, and, be convenient to install.
Description of drawings
Fig. 1 is first embodiment's of the utility model vertical shield pump a structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified, but not as to qualification of the present utility model.
See also the embodiment of the utility model vertical shield pump shown in Figure 1, canned motorpump, comprise casing 6, rotor 5, stator 4, impeller 1, axle 8, go up trunnion shaft bearing 7, following trunnion shaft bearing 2, described impeller 1 is located at the bottom of axle 8, and following trunnion shaft bearing 2 is positioned at impeller 1 top, and floral disc 3 is enclosed within down outside the trunnion shaft bearing 2, rotor 5 is positioned at the middle part of axle 8, stator 4 is enclosed within outside the rotor 5, and last trunnion shaft bearing 7 is positioned at the upper end of axle 8, is nested in outside the axle 8.
Above-described embodiment, the utility model embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solutions of the utility model scope and replacing all should be included in the protection domain of the present utility model.
