What are the objectives of flow switches and water flow switches?

Flow switches are installed online or plug-in in media pipelines such as water, gas, and oil to monitor the water flow rate in the water system When the flow rate is higher or lower than a certain setting, it will trigger the output alarm signal to be transmitted to the unit After observing the signal, the system will make corresponding indication actions, which can effectively avoid or reduce the occurrence of ^ ^ dry burning ^ ^ of the host This article mainly introduces the types of flow switches, the working principle of flow switches, installation precautions for flow switches, and flow switch pictures

1. Definition of flow switch: A flow switch is a sensing controller that uses variable principles to measure the flow of media in a pipeline and transmit real-time off signals to back end devices

2. The purpose of flow switch: Flow switch is to command the system's switch based on flow Set an upper or lower limit for the flow switch When the flow reaches this limit value, the flow switch sends a signal or alarm, and the system will run or stop Generally, systems that require flow will use flow switches Dependence on the system and factors such as flow switch models, the location of use variables and dependencies on the specific situation Plunger type water flow switch

3. Working principle of flow switch: When there is water flow in the water flow switch, and the water flow rate is ≥ 1.0L/min, the magnetic core inside the water flow switch is driven by the water flow to generate display The magnetic core display drives the magnetic source to generate magnetic control, causing the water flow switch to output a ^ ^ on ^ ^ signal The automatic selection of flow switch for fast and easy optimization is included This signal is input into the equipment control system, and the control function is achieved through the control system When the water flow rate is less than the starting flow rate, the flow switch outputs a ^ ^ off ^ ^ signal The control system products the candidate control effect as described above In other words, when the water flow rate in the pipeline is greater than 1L/min, the magnetic core products display under the action of water flow and drives the magnetic source to generate magnetic control, causing the sensor to output a ^ 1 ^ ^ ^ switch signal This signal is input to the equipment control system, and after power amplification, the purpose of water flow control is achieved When the water flow rate in the pipeline is less than 1L/min, the magnetic core drives the magnetic source to return to its position under the rust of the reset spring, causing the sensor to output a ^ ^ 0 ^ ^ switch signal and stop the system's operation Flow switches have advantages such as high sensitivity and strong durability Unit price of flow switch

4. Advantages of flow switch: 1 Low flow rate (quantity) action of water flow switch; 2. The water flow switch has a simple structure and a small contact surface for action; 3. The water flow switch can also be used for low content debis water flow; When the water flow switch is blocked by special fabrics, it can be cleared online
