What is water flow switch? Water flow switch is a common type of flow detective device. It mainly detects the dynamic state of water flow, with the advantages of flexible use, stable performance, high reliability, simple maintenance, long service life, etc. Nowadays, we mainly introduce the application of water flow switch, hoping to help users better application for this products.
In some large equipment and machines, circulating water is usually used to cool the unit, so as to ensure the working temperature of the unit in a reasonable range. When the cooling water system fails, if the water flow stops, it will cause the temperature of the unit to rise, affect the normal operation of the unit, and seriously may cause the unit to burn out. Generally, a water flow switch will be installed in the pipe of the cooling water system to monitor the flow status of the cooling water in real time. Once the cooling water stops flowing, the water flow switch will send an alarm signal to the central control room, so that the central control room can handle it in time and avoid accidents.
Generally, there are three main kinds of water flow switches, one is the early mechanical flow switch, also known as the baffle paddle flow switch. Its principle is to push the paddle to detect the flow of water, and then touch the microswitch. The mechanical flow switch has the advantages of convenient use and low price. The disadvantages are that the mechanical structure will wear out, and the action is not very stable when the water quality is not good.
