Impurity test bed

Abstract

The embodiment of the invention discloses an impurity test bed, comprising a test water tank, a stirrer and a circulatory system, wherein the stirrer is arranged at the bottom of the test water tank; the circulatory system is communicated with the test water tank; the test water tank is used for containing liquid containing impurities and allowing a device to be tested to be soaked in the liquid containing impurities; the stirrer is used for stirring the liquid containing impurities which is contained in the test water tank to keep the liquid to be turbid; and the circulatory system is used for driving the liquid in the test water tank to pass the device to be tested continuously. The impurity test bed disclosed in the embodiment of the invention has stable performance, smaller fluctuation of test situations and high measurement accuracy, thus being suitable for serving as nuclear power equipment.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an impurity test bench. Background technique [0002] In nuclear power plants, the reliability requirements for equipment are very strict. In the event of an accident in a nuclear power plant, whether the equipment can continue to operate normally is also a key indicator of its reliability. In the event of design basis accidents in PWR nuclear power plants (design basis accidents refer to those accident conditions in which targeted measures have been taken in the design of nuclear power plants according to established design criteria, such as loss of coolant or rupture of main steam pipes), safe injection The system (RIS) (hereinafter referred to as the safety injection system) and the containment sprinkler system (EAS) pump water from the pit to cool the reactor core and containment for a long time, avoiding serious damage to the core and overpressure of the containment. But after the ac...

Problems solved by technology

[0004] However, the inventor found in the process of implementing the present invention that there is no professional impurity test bench for detecting nuclear power equipment at present, and the performance of the existing impurity test bench is often unstable, and the test state fluctuates greatly, making the measurement Low precision, not suitable as impurity test bench for nuclear power equipment
