Description
Technical field
The invention belongs to Nuclear Power Station power engineering technology fields, and in particular to a kind of reactor coolant pump kingbolt drawing
Stretch simulator.
Background technology
In the disassembling overhaul of nuclear reactor coolant pump, it will be related to one compared with based on and very important repair
Process, that is, equally distributed 30 kingbolts on the main faying face of nuclear reactor coolant pump are carried out tight work.Tight
Process bolt stretching machine is coordinated using hydraulic power unit, carried out by way of stretching kingbolt tight, according to technology
Tight work is completed it is required that needing to reach specified amount of tension and specified torque and can be regarded as.General kernel is anti-before disassembling overhaul
Reactor coolant pump region is answered to be in blocked styate, this allows for that reality can not be seen before nuclear reactor coolant pump disassembling overhaul
Object is operated, before traditional overhaul training generally explained in the form of video and picture, not enough intuitively.Repair
Personnel often also need to relearn and adapt in practical overhaul after the completion of training, reduce working efficiency, increase maintenance
Time and collective dose are unfavorable for the requirement of safety in production simultaneously because operation is unskilled to also increase security risk.
Invention content
Present invention solves the technical problem that：
The present invention provides a kind of reactor coolant pump kingbolt stretching simulator, being capable of mock-up reactor coolant pump
Kingbolt actual condition, fitted bolt stretching-machine reach kingbolt the simulated operation tightly to work.
The technical solution adopted by the present invention：
A kind of reactor coolant pump kingbolt simulator, including bottom plate, fixing nut, main flange simulating piece, gasket
Bucket, butterfly gasket, lower spherical washer, upper spherical washer, nut, kingbolt, fixing nut are fixedly connected with bottom plate, bottom plate and ground
Face is fixed；Kingbolt screws in fixing nut；Main flange simulating piece is inserted in kingbolt；Gasket casing is entered into kingbolt；If dry plate
Butterfly gasket is installed after being inserted in kingbolt into gasket bucket；Lower spherical washer is installed after being inserted in kingbolt to butterfly gasket；
Upper spherical washer is placed in lower spherical washer, rotates and movement is allowed to all directions uniformly and is bonded；Nut screws in kingbolt top
Portion.
Ensure that the top layer of fixing nut is horizontal.
It adjusts main flange simulating piece horizontal position and so that it is concentric with fixing nut.
Adjust pad bucket horizontal position so that it is concentric with main flange simulating piece.
The fixing nut, main flange simulating piece, gasket bucket are using stainless steel bar as raw material；Lower spherical washer, on
Spherical washer uses hard stainless steel material, nut to be process using stainless steel column.
Beneficial effects of the present invention：
(1) a kind of reactor coolant pump kingbolt provided by the invention stretches simulator, can simulate live practical
Kingbolt structure under operating mode；Live kingbolt can be simulated to stretch tight process；
(2) a kind of reactor coolant pump kingbolt provided by the invention stretches simulator, simple in structure easy to process
It is of low cost, it is high with actual condition kingbolt position and structural similarity, it is high with bolt stretching machine compounding practice simulation degree, just
The expansion of training before overhaul reduces job safety wind to effectively improve skill proficiency when maintenance personal's overhaul
Working efficiency is improved in danger, reduces collective dose value.
