Abstract
The utility model relates to a permissible motor used in a pressurized water reactor nuclear power plant containment. The permissible motor is mainly composed of: a shaft, a stretch end bearing assembly, front and rear end covers, a wind shield, an engine base, a stator coil, a rotor copper bar, a rotor end ring, an inner fan, a junction box, a non-stretch end bearing assembly, an outer fan and the like. A stator core is positioned in the engine base. The stator coil is embedded in the stator core. A rotor core is mounted on the shaft. The rotor copper bar is inserted in the rotor core. The rotor end ring, a retaining ring and the inner fan are installed on the shaft. The shaft is inserted in the engine base. One end of the wind shield is installed on the front end cover, and the other end is mounted on the rear end cover. The stretch end bearing assembly is mounted on a shaft stretch end of the shaft. The non-stretch end bearing assembly is installed on a non-shaft stretch end of the shaft. The outer fan is mounted on the shaft. The product has a simple structure, and it can meet operating requirements of a nuclear power plant circuit working condition on earthquake resistance, radiation resistance, high temperature resistance, resistance to strong acid and strong base and resistance to ocean climate corrosion temperature impact. When a loss of coolant accident happens, the motor can operate normally.
Description
Technical field: the utility model relates to uses the safe level motor in a kind of Containment for PWR Nuclear Power Plant.
Background technology: at present, motor used in pressurized-water reactor nuclear power plant safe level containment adopts the motor of external import mostly, it is expensive, after damage of components, maintenance cycle is long, inconvenience, and it is antiseismic that the motor of domestic production can not satisfy nuclear power station one loop operating mode, the instructions for use of radiation hardness, high temperature resistant, anti-strong acid, highly basic and the impact of ocean climate corrosion temperature etc., when running into loss-of-coolant accident, motor can't normally move.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, provide and use the safe level motor in a kind of Containment for PWR Nuclear Power Plant, it has mainly solved the motor that motor used in pressurized-water reactor nuclear power plant safe level containment adopts external import, expensive, after damage of components, long and motor domestic production of maintenance cycle can not satisfy nuclear power station one loop operating mode instructions for use, and when running into loss-of-coolant accident, motor such as can't normally move at the problem.The purpose of this utility model is achieved in that in Containment for PWR Nuclear Power Plant with the safe level motor by: axle, stretches end bearing assembling, front end housing, deep bead, support, stator coil, stator core, rotor core, copper bar rotor, rotor end ring, retaining ring, internal fan, terminal box, rear end cap, non-end bearing assembling, external fan, the fan guard formation of stretching.Stator core is arranged in support, stator coil is embedded in stator core, rotor core is arranged on axle, copper bar rotor is inserted in rotor core, rotor end ring, retaining ring are arranged on axle, internal fan is arranged on axle, axle is inserted on support, deep bead one end is arranged on front end housing, the other end is arranged on rear end cap, stretches the end bearing erection at the shaft extension end of axle, and the non-end bearing erection of stretching is at the non-shaft stretching end of axle, external fan is arranged on axle, and fan guard, terminal box are arranged on support.This product structure is simple, and is reasonable in design, and it is antiseismic that it can satisfy nuclear power station one loop operating mode, the instructions for use that radiation hardness, high temperature resistant, anti-strong acid, highly basic and ocean climate corrosion temperature impact, when running into loss-of-coolant accident, motor can normally move, and manufacturing cost is low, and is easy to maintenance.
