What is the resistance value of Haier solar electric heating tube?

Introduction What is the resistance value of a Haier solar electric heating tube? Use a small resistance level to measure the terminals on both ends of the heating tube. The resistance should be less than several hundred ohms. be smaller.

What is the resistance value of Haier solar electric heating tube?

Use a small resistance level to measure the terminals on both ends of the heating tube. The resistance should be less than several hundred ohms. The resistance of a high power electric heating tube will be smaller and the energy will pass through. , if the resistance value is high, the electric heating tube may have burned out.

Use the high resistance setting of the meter to measure the resistance between the wiring pile head and the heating tube shell. If the resistance is only a few tens of kiloohms, the insulation of the heating tube must be infinite. The electric heating tube is broken, there is a risk of leakage during use, so it is better not to use such heating tubes. If it's open or short, it's bad. Since the joints have been exposed to high temperatures for a long time and are heavily oxidized, sandpaper should be used tor remove rust during measurement.

What should I do if the electric heating area under the large drum of the solar water heater is leaking?

The electric heating pipe of the solar electric water heater is threaded, with diameters of 4 minutes, 6 minutes and 1 inch available. Use a tool to unscrew the old electric heater pipe and replace it. with the threaded opening of the same diameter. There is no advantage to using electric heating over solar energy. Simply install one directly in the house. If it has this function, just connect the power cord to the heating tube terminal. The thread should be 2.5 or more. directly with a socket. It is best to install a circuit breaker. Current calculation: total power of the heating tube/220 = current Choose a circuit breaker 1.5 times larger than the calculated current.?

Is it normal for solar electric heatinge has a short circuit?

First of all, if there is water leakage from the electric heating rod, do not use the electric auxiliary heating function to avoid the risk of electric shock due to leakage during use.

It can be seen from the picture above that the water heater has been used for a long time and is badly corroded. If the solar energy is normal (the temperature increase of the vacuum tube heater is not much different from when it was first purchased), you can continue to use the solar heater if the solar heating speed is significantly slower than before and take corrosion into account. of the water tank and the bracket, if the corrosion is significant, it is recommended to replace the solar energy water heater.

If there are no major problems elsewhere, disassemble and inspect. First, determine the water temperature in the solar panel, make sure it is nothigh (to avoid burns during disassembly) and drain all water from the solar panel. Remove the electric heating tube to replace it. Normally, there are two ways to fix the electric heating tube, one is fixed by sealing ring, without screws to specify the heating tube; the other is fixed by screws, you can pull; it came out forcefully with screws opened by screws. Check the sealing ring. Due to water leakage, the sealing ring must be broken. Remove the seal ring and buy a new one. At the same time check whether the electric heating rod is scaled. If the scaling is significant, it is recommended to clean or replace it. If the electric heating rod is heavily scaled, the scale in the vacuum tube must also be large. Find a professional solar installer to clean it depending on the situation.

To reduce the risk, if electric heatingthat is not used frequently, you can remove the electric heater and use a plug to block the hole of the electric heater.

The short circuit of the solar electric heater is abnormal. The electric heating tube may be broken or the electric heating wire may be too thin and burned after prolonged use.

Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature.Meet the people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Domestic evacuated tube solar water heaters are compdated heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the hot water principle. float and sink cold water to cause microcirculation in the water. Get the hot water you need.
