How to repair the solar solenoid valve is broken
4, in addition, the electromagnetic valve is a low voltage (typically +12V) start running on the line, if the conductor somewhere or poor contact leakage may cause the solenoid valve does not work, so to check whether the good contact wire joint. For the working condition of the solenoid valve is good or bad, it is difficult to use the multimeter to measure the quality of the connection wire, then you can replace the solenoid valve or replace the conductor try.Solenoid valve is an electromagnetic control of industrial equipment, is used to control the automation of the basic components of the fluid, is the actuator, is not limited to hydraulic, pneumatic. Used in industrial control systems to adjust the direction of the media, flow, speed and other parameters. Solenoid valve can be combined with different circuits to achieve the desired control, and control accuracy and flexibility can be guaranteed.
In 2, the next from any resistance solenoid valve terminal in the wires, if the measured resistance value of normal said in 40 ohm, and if the resistance value is very large, is that the internal coil of the electromagnetic valve is open; if the resistance is too small, the internal short circuit coil. If the coil open or short circuit, need to change.3, due to the solar water heater electric connection line is longer, bending parts, and some of the lines are placed outdoors, so in the actual maintenance should also be measured whether the connection wire is normal. Disengage all the connecting ends of the wire, measure the resistance between the lines with a multimeter (normally should be the same), and whether the same line is clear (normally 0).
Solar solenoid valve failure, fault detection and repair methods are as follows:1, first of all, from a control wire terminals of the terminal apparatus connected with an electromagnetic valve in the inlet start function control meter, multimeter DC 50V gear measuring and controlling instrument electromagnetic valve on the voltage output terminal voltage, if the voltage at 9V ~ 15V, showed that the normal control instrument, or control instrument failure; if the voltage is normal, the fault may be in the wire and the electromagnetic valve.
