Abstract
The invention discloses a pressure-proof heat insulation screen inside a full-sealing pump. The pressure-proof heat insulation screen inside the full-sealing pump comprises a heat insulation screen body (1). A central through hole used for penetrating through a motor rotating shaft is formed in the center of the heat insulation screen body (1). A heat insulation cavity surrounding the central through hole is formed inside the heat insulation screen body (1). A strengthening skeleton (2) is arranged inside the heat insulation cavity. By the adoption of the structure, the overall structure is simple, and the pressure-proof heat insulation screen is convenient to achieve. When the pressure-proof heat insulation screen is applied, the heat insulation performance of the pressure-proof heat insulation screen is strengthened through the heat insulation cavity, the structural intensity when the pressure-proof heat insulation screen is applied is ensured through the strengthening skeleton (2), and the thickness of the heat insulation screen body (1) can be reduced under the effect that the structural intensity is ensured by the strengthening skeleton (2). Therefore, the heat transfer area of the heat insulation screen body (1) can be reduced, the heat insulation effect is improved, and therefore the pressure-bearing function and the heat insulation function can be achieved at the same time when the pressure-proof heat insulation screen is applied.

Described web frame comprises multiple-layer horizontal supporting framework, every layer of a plurality of longitudinal supporting spare that the horizontal supporting framework includes a plurality of lateral support member of laterally arranging and is connected and vertically arranges with lateral support member, the two-layer horizontal supporting framework of the arbitrary neighborhood at the middle and upper levels lateral support member of horizontal supporting framework and the tie point between the longitudinal supporting spare is corresponding one by one with lateral support member and the tie point position between the longitudinal supporting spare of lower floor horizontal bearing support structure, and horizontal any one tie point of bearing support structure in upper strata with its over against the tie point of lower floor's supporting framework between be connected by vertical link.The present invention reaches vertical link stereo staggered on three directions in space by lateral support member, longitudinal supporting spare and weaves and connect and compose web frame, improved the structural strength of web frame, and then the bearing capacity when having improved web frame of the present invention and using.
Be convenient to draw materials and be connected because of cylindric rib, as the first mode of execution of web frame, described lateral support member, longitudinal supporting spare reach vertical link and are cylindric rib.
Because tabular gusset is convenient to draw materials and is connected, and have good structural strength, as the second mode of execution of web frame, described lateral support member, longitudinal supporting spare reach vertical link and are tabular gusset.
In order to strengthen the structural strength of the web frame that tabular gusset consists of, described lateral support member and longitudinal supporting spare all are connected with the reinforcement gusset, and described reinforcement gusset two ends are connected on two vertical links that are adjacent.
As the third mode of execution of web frame, described web frame comprises many ring pipes, and many ring pipe close alignment are arranged or are staggered.When present embodiment was used, the ring pipe that is positioned at heat insulation cavity closely supported the pressure outside of transmitting to bear the heat screen body mutually.
As preferably, the section of described ring pipe is circular, ellipse or polygonal.
Described heat insulation cavity consists of circular cavity, and described web frame is that axisymmetric torus shape is arranged.The present invention is when other practical application, and the web frame of above-mentioned the first mode of execution and the second mode of execution also can be comprised of several frameworks by rectanglar arrangement.
Compared with prior art, the present invention has following beneficial effect: the present invention includes the heat screen body, wherein, the heat screen body interior consists of heat insulation cavity, be provided with web frame in the heat insulation cavity, heat-shielding performance when the present invention can strengthen the present invention and uses by heat insulation cavity is unlikely to excessive deformation and can avoid the present invention to bear high-pressure liquid medium as the time spent under the effect of web frame; Under the effect of web frame, improved structural strength of the present invention, thickness that can attenuate heat screen body, and then reduce the area of contact of heat screen body and machine shaft, improve effect of heat insulation, with the safe and stable operation of assurance shield electric machine.
