A new mobile emergency diesel engine-driven water injection device for nuclear power plants

Abstract

The invention discloses a novel mobile emergency diesel driven water injection device for a nuclear power station. The novel mobile emergency diesel driven water injection device comprises a water injection pump unit, a drive device used for driving the water injection pump unit, and a mobile load device used for bearing the pump unit and the drive device, wherein the drive device is a diesel engine, an output shaft of the drive device is connected with an input shaft of the water injection pump unit through a clutch, the clutch is used for controlling whether the drive device provides power to the water injection pump unit; the drive device and the water injection pump unit are arranged on the mobile load device. According to the invention adopting the technical scheme, the drive device drives the water injection pump unit to inject water, and a targeted monitoring device and a targeted regulating device are arranged in a pipeline of the water injection pump unit for ensuring that the water injection amount is controlled in real time; the novel mobile emergency diesel driven water injection device is installed on the mobile load device, thus the maneuverability of the novel mobile emergency diesel driven water injection device is ensured.

Description

technical field [0001] The invention relates to water injection equipment, in particular to a water pump system equipment driven by a mobile emergency diesel engine for nuclear power plants. Background technique [0002] At present, once domestic nuclear power plants are completely paralyzed due to force majeure (earthquakes, tsunamis, etc.) and power outages occur, the temperature of the nuclear reactors in the nuclear island will rise rapidly due to lack of water or lack of water, and the loss of control will cause nuclear leakage disasters. Therefore, it is required to have a device that can quickly inject water into the core of the nuclear reactor to take away the heat when there is no electricity. This requires an emergency water injection equipment that can be quickly installed on the spent fuel when there is no water or electricity. The position of the water tank should be started as soon as possible, and it can continue to operate when there is a water source, and in...
