Description
Technical field
The present invention relates to a kind of insulating layer structure, the withstand voltage heat screen specifically in glandless motor pump.
Background technique
Nuclear-energy plant glandlesspump adopts all-sealed structure to bear the High Temperature High Pressure primary Ioops medium from hydraulic part entrance to hydraulic part outlet stream, motor and hydraulic part are linked to be an entirety and are in the liquid within glandless motor pump pressure boundary, in order to ensure that motor is in the lower temperature range of safe operation, there are heat screen parts between hydraulic part and motor, heat screen parts not only need the high pressure bearing primary Ioops, also should ensure that there is good effect of heat insulation, motor temperature is made to exceed the allowable temperature of insulation to avoid the high temperature of pump hydraulic part part to transmit to motor place, and finally cause motor failure.Now when designing heat screen, thickness generally by increasing heat screen improves its bearing capacity, but, the thickness increase of heat screen can cause heat screen heat transfer area to strengthen, the high temperature of hydraulic part position is also increased by the heat of heat screen to motor transmission thereupon, and this just makes the effect of heat insulation of heat screen greatly decline.
Summary of the invention
The object of the invention is to solve heat screen now and can affect the problem of its heat-shielding performance when improving bearing capacity, provide a kind of withstand voltage heat screen that also can ensure under the condition meeting bearing capacity in the glandless motor pump of heat-shielding performance, which solve existing heat screen pressure-bearing and the heat insulation problem that can not take into account.
Object of the present invention is achieved through the following technical solutions: the withstand voltage heat screen in glandless motor pump, comprise heat screen body, heat screen body center arranges the central perforation be used for through machine shaft, heat screen body interior is configured with the insulated cavity around central perforation, is provided with web frame in described insulated cavity.Insulated cavity of the present invention not only has the effect arranging web frame, can reduce the heat transmitted through heat screen body under the effect of insulated cavity, strengthens heat-shielding performance when the present invention applies.
Described web frame comprises multiple-layer horizontal supporting framework, every layer of horizontal supporting framework includes the lateral support member of multiple laterally arrangement and is connected with lateral support member and multiple longitudinal bearer of longitudinally arranging, tie point position one_to_one corresponding between the lateral support member of the horizontal bearing support structure of tie point and lower floor of arbitrary neighborhood two-layer horizontal supporting framework at the middle and upper levels between the lateral support member of horizontal supporting framework and longitudinal bearer and longitudinal bearer, and upper strata any one tie point of horizontal bearing support structure and its just right lower floor support framework tie point between be connected by vertical link.The present invention is woven by lateral support member, longitudinal bearer and vertical link stereo staggered on direction, three, space and is connected and composed web frame, improve the structural strength of web frame, and then improve bearing capacity when web frame of the present invention is applied.
Because cylindric rib is convenient to draw materials and be connected, as the first mode of execution of web frame, described lateral support member, longitudinal bearer and vertical link are cylindric rib.
Because tabular gusset is convenient to draw materials and be connected, and have good structural strength, as the second mode of execution of web frame, described lateral support member, longitudinal bearer and vertical link are tabular gusset.
In order to strengthen the structural strength of web frame that tabular gusset is formed, described lateral support member and longitudinal bearer are all connected with reinforcement gusset, and described reinforcement gusset two ends are connected on two vertical links being adjacent.
As the third mode of execution of web frame, described web frame comprises many ring pipes, and many ring pipe close alignment arrange or are staggered.During present embodiment application, the ring pipe being positioned at insulated cavity closely supports the pressure outside of bearing the transmission of heat screen body mutually.
As preferably, the section of described ring pipe is circular, oval or polygonal.
Described insulated cavity forms circular cavity, and described web frame is the arrangement of axisymmetric torus shape.The present invention is when other practical application, and the web frame of the first mode of execution above-mentioned and the second mode of execution also can be made up of several frameworks by rectanglar arrangement.
Compared with prior art, the present invention has following beneficial effect: the present invention includes heat screen body, wherein, heat screen body interior is configured with insulated cavity, web frame is provided with in insulated cavity, the present invention can strengthen heat-shielding performance when the present invention applies by insulated cavity, and is unlikely to excessive deformation when the present invention can be avoided under the effect of web frame to bear high-pressure liquid medium effect; Structural strength of the present invention is improve under the effect of web frame, can the thickness of thinning heat screen body, and then reduce the area of contact of heat screen body and machine shaft, raising effect of heat insulation, to ensure the safe and stable operation of shield electric machine.
