DI (deionized) water supply system and application method thereof

Abstract

A DI (deionized) water supply system comprises a DI water storage mechanism, a DI water pumping mechanism and a DI water consuming mechanism. The DI water storage mechanism, the DI water pumping mechanism and the DI water consuming mechanism are connected sequentially through a pipeline; a return water line is connected between the DI water pumping mechanism and the DI water consuming mechanism; the return water line is communicated with the DI water storage mechanism. The DI water supply system relieves pressure by means of reflowing; the water hammer effect can be relieved or eliminated uponsudden startup of a water pump; the automation level is high, all operations are automatically controlled via a controller, and complex manual operations are not required; in addition, the DI water supply system is simple in structure and is suitable for long-term usage with no need for frequent maintenance.

Description

technical field [0001] The invention relates to a water supply system, in particular to a DI water supply system capable of eliminating the water hammer effect and a using method thereof, belonging to the field of water supply systems. Background technique [0002] The water hammer effect is a vivid statement. It refers to a serious water hammer caused by the water flow hitting the pipeline when the feed water pump starts and stops. Because inside the water pipe, the inner wall of the pipe is smooth, and the water flows freely. When the open valve is suddenly closed or the feedwater pump stops, the water flow will generate a pressure on the valve and the pipe wall, mainly the valve or the pump. Due to the smooth pipe wall, under the action of inertia of the subsequent water flow, the hydraulic force quickly reaches the maximum and produces damage. This is the "water hammer effect" in hydraulics, that is, positive water hammer. On the contrary, the closed valve will also pr...

AI Technical Summary

Problems solved by technology

This water hammer eliminator can eliminate the water hammer effect to a certain extent, but for a long time, due to the influence of the water hammer effect, the sealing performance of the bottom of the cylinder is reduced, and the control operation of the three-way valve is extremely cumbersome. , the work efficiency is extremely low, and there are a lot of accessories required, and the structure is extremely complicated, which has a certain impact on production and processing.
