Abstract

The primary loop emergency water supplementing diesel engine pump set comprises a base and a water tank support which are installed in a carriage, and the base is located on the left side of the water tank support. The base is used for installing a diesel engine, a speed regulation gear box and a centrifugal pump of the pump set, an output shaft of the diesel engine is connected with the input end of the speed regulation gear box, and the output end of the speed regulation gear box is connected with a pump shaft of the centrifugal pump through a coupler; a self-suction water tank is arranged on the water tank support, an inlet of the self-suction water tank is connected with a water tank water inlet pipe, an outlet of the self-suction water tank is connected with an inlet of the centrifugal pump through a pump water inlet pipe, and the liquid level in the self-suction water tank is higher than a water outlet of the centrifugal pump. After the pump set is provided with the self-suction water tank, vibration and noise of the pump set can be effectively reduced, and therefore operation of the pump set is more stable and reliable.

Description

technical field [0001] The invention relates to the technical field of emergency water replenishment pumps, in particular to a primary circuit emergency water replenishment diesel engine pump set with a self-priming water tank. Background technique [0002] The primary circuit emergency water supply diesel engine pump is used to put into operation within 2.5 hours after the accident, replenishing water to the primary circuit and cooling the reactor core; the diesel engine drives the rotation of the rotor, drives the rotation of the pump rotor through the speed increaser box and the coupling, and relies on the rotating impeller to The dynamic action of the liquid continuously transfers energy to the conveying liquid (water or boron-containing water), which increases the kinetic energy (mainly) and pressure energy of the liquid, and then converts the kinetic energy into pressure energy through the pump chamber’s extrusion chamber. When the liquid is thrown from the impeller, t...
