A sun rain licensing solar water heater manual electric heating, overflow, can not automatically stop Sheung Shui, what is the reason?
Water leakage of water tank is one of the most common failures of solar water heater. The location of the water tank is relatively high, can overflow from here, indicating that the water tank is still full of water, there are many reasons:
Two. Solenoid valve failure. The probability of such a failure is not equal to that of the probe. Determine the way: the instrument power off, then the tank also continues to overflow, and then turn off the solenoid valve before the cold water, then, the water tank stopped. In this way, you can determine the solenoid valve failure. The solution is to replace the solenoid valve.Three. The cold and hot water mixing valve of hot and cold water communication. The probability of such failure is not much, but there are also. The judgment way: the instrument power off, then the water tank water inlet switch off, then continue to overflow, the first tank hot water outlet is closed, then the tank does not overflow, then you can judge the fault reason of mixing valve. As long as the failure of the mixed valve can be replaced.
Probe failure. This is one of the most common causes. Instrument through the control solenoid valve to control the automatic water supply and automatic water off the solar water heater, the premise is that the feedback signal to the instrument must be correct. If the feedback signal from the probe is wrong, then the command given by the instrument is also wrong. If the probe fails, when the water in the water tank is full, the signal feedback to the probe instrument is still not full, instrument commands were solenoid valve to open, that is to continue to water, then the water will overflow through the stomata. How to determine the reason for the failure of the probe? Very simple, if the water tank overflow, then the meter has not been full of water level, it can be judged that the probe failed. The solution, of course, is to replace the probe.
