Description
Technical Field
The invention relates to the technical field of water purification treatment, in particular to a system and a method for eliminating water hammer benefit of a water purifier filter system.
Background
The water hammer effect means that the inner wall of the water pipe is smooth and water flows freely inside the water pipe. When the opened valve is suddenly closed, the water flow generates a pressure on the valve and the pipe wall, mainly the valve. Because the pipe wall is smooth, the follow-up water flow quickly reaches the maximum under the action of inertia and generates destructive action, namely 'water hammer effect' in water conservancy, namely positive water hammer. The factor is considered in the construction of water conservancy pipelines. On the contrary, after the closed valve is suddenly opened, a water hammer, called a negative water hammer, is generated, and has certain destructive power, but the water hammer is not as large as the negative water hammer.
When a user suddenly opens and closes the water purifying faucet, the pressure of the high-pressure switch suddenly changes due to the water hammer effect, the high-pressure switch is closed or opened, and the water purifying machine is caused to open or close the booster pump. Frequent starting and stopping of the booster pump can seriously shorten the service life of the booster pump. For a high-flux catering water purifier, a plurality of kitchen catering equipment are connected behind the water purifier, and the frequent switching of the equipment causes the booster pump of the water purifier to be frequently started and stopped due to the water hammer effect, the service life of the booster pump is seriously influenced, and the booster pump is damaged.
