A nuclear power main pump test device

Abstract

The invention relates to a nuclear power main pump test device. At present, only minority countries master the design technology of nuclear power main pumps around the world. The nuclear power main pump test device is characterized in that a test pump motor is a shielding main pump motor or a shaft seal main pump motor, a shielding main pump shell, a sixth reducing joint, an eighth reducing joint, a first main regulating valve, a seventh reducing joint, a shaft seal main pump shell, a first reducing joint, a second reducing joint, a first damping screen, a first Venturi tube flow meter and a third reducing joint are sequentially arranged on a loop main pipeline, a fourth reducing joint, a second damping screen, a second Venturi tube flow meter and a fifth reducing joint are sequentially arranged on a flow parallel-connection measurement pipe, a ninth reducing joint, a second main regulating valve and a tenth reducing joint are sequentially arranged on a main valve parallel-connection measurement pipe, the shielding main pump motor is arranged on the shielding main pump shell, or the shaft seal main pump motor is arranged on the shaft seal main pump shell. The nuclear power main pump test device has the functions of a test shielding main pump and a shaft seal main pump.

Description

technical field [0001] The invention relates to a nuclear power main pump test device, which is used for the high temperature and high pressure full performance test of the nuclear power main pump, mainly used for the test test of the shielded motor main pump and the shaft seal main pump, and is especially suitable for the full performance of the third generation nuclear power main pump. test. Background technique [0002] The large-scale advanced pressurized water reactor nuclear power plant is a sub-item of one of the 16 major national science and technology projects identified in the "National Medium and Long-Term Science and Technology Development Program (2006-2020)". Reactor coolant pump, as one of the key equipment in the primary circuit system of the pressurized water reactor nuclear power plant, plays an important role in the energy conversion of the nuclear power plant, and is known as the heart of the reactor cooling system. At present, the main pumps used in dom...
