Abstract
The utility model relates to a bolt insulation sealing structure of motor stator lead wires. The bolt insulation sealing structure comprises a machine base, a pressing plate, a pressing plate bolt, a pedestal insulator, a screw nut, a gasket, a belleville spring, a wiring bolt, a ceramic insulation sleeve, a foundation base, a tapered copper pad and a subplate, wherein the wiring bolt, the ceramic insulation sleeve and the foundation base are welded together and installed on the subplate; the subplate is installed on the machine base; the tapered copper pad is installed on the machine base; the pressing plate is installed on the machine base through the pressing bolt; the pedestal insulator, the belleville spring and the gasket are sleeved on the wiring bolt respectively and screwed on the pressing plate through the screw nut. The product is simple in structure and reasonable in design; since the bolt is provided with the tapered copper pad, the wiring bolt is unlikely to rotate, and under the actions of internal pressure and external pressure, the tapered sealing pad compresses more and more tightly, so that the sealing is safer and more reliable; the wiring bolt, the ceramic insulation sleeve and the foundation base are welded together so as to enable the sealing to be reliable, and the bolt insulation sealing structure can bear high temperature and high pressure, so that the bolt insulation sealing structure has the same service life with the machine base, and the maintenance is omitted.
Description
Technical field:
The utility model relates to a kind of bolt insulation and sealing structure of motor stator lead wire.
Background technology:
At present, the bolt that the motor stator lead wire on the nuclear-powered submarine main pump uses is installed in the terminal box through rubber blanket, because bolt does not have anti-rotation structure; Insulating case is torn easily during rotation, and is poorly sealed, influences sealing effectiveness; In addition, adopt the O RunddichtringO, the sealing ring easy ageing.
Summary of the invention:
The purpose of the utility model is to overcome above-mentioned shortcoming; A kind of bolt insulation and sealing structure of motor stator lead wire is provided; It has mainly solved bolt that the motor stator lead wire uses owing to there is not anti-rotation structure; Insulating case is torn easily during rotation, and is poorly sealed, influences problems such as sealing effectiveness.The bolt insulation and sealing structure that the purpose of the utility model is achieved in that the motor stator lead wire by: support, pressing plate, follower bolt, standoff, nut, packing ring, butterfly spring, connection bolt, ceramic insulation cover, pedestal, taper copper packing, backing plate constitute.Connection bolt, ceramic insulation cover, pedestal weld together; And be installed on the backing plate; Backing plate is installed on the support, and the taper copper packing is installed on the support, and pressing plate is installed on the support through follower bolt; Standoff, butterfly spring, packing ring are set on the connection bolt, and are screwedly mounted on the pressing plate through nut.This product structure is simple, and is reasonable in design, because the taper copper packing is housed on bolt; Connection bolt is difficult for rotating, and under the effect of interior pressure or external pressure, conical gasket can be pressed tighter and tighter; The sealing safety and reliability, connection bolt, ceramic insulation cover, pedestal weld together, and sealing is reliable; And can bear HTHP, and realize and the same equivalent life of support, avoid maintenance.
