Do you understand the installation and use of water flow switches?
The water flow switch, also known as the flow switch, is applied in the water system of children and air conditioning engineering to ensure the safety and effective operation of the air conditioning system Usually, the water flow switch can only qualitatively ensure the safety and effective operation of the air conditioning system when applied, and cannot quantitatively and accurately set the flow value when the water flow switch is closed and open When the water flow rate changes, the force generated by the water flow on the target causes the lever to rotate, closing or disconnecting the control circuit, there being the purpose of automatic control Control
The water flow switch insists of a magnetic core, a return spring, a forced copper or polycarbonate casing, and a sensor The function of the water flow switch is:
1. Detect where the liquid is in the pipeline flows and where the amount of flow (flow rate, ie. liquid flow pressure) meets the requirements, while outputting (providing) a signal on/off state through the switch electrical contact
2. The equipment system judges the working condition of the Plumbing by detecting where there is a signal or control current passing through the switch (on/off state of the electric contact of the water flow switch), and gives the corresponding control or operation mode or measures
1. Working principle
When the water flow rate in the pipeline is greater than 0.75L/min, the magnetic core generates 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 0.75L/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
2. Installation method
Vertical installation: When installed vertically, it should be installed on the pipe section that flows from bottom to top
Horizontal installation: When installing on the upper end of a horizontal pipeline, ensure that the medium is full to prevent the probe from only coming into contact with air and not the medium
Inverted installation: When installed at the lower end of a horizontal pipeline, it should be ensured that there is no division at the bottom of the pipeline to prevent the probe from being covered by division and unable to fully contact the probe
