How to wire the water level sensor of solar water heater?

The operation is as follows:

1. The solar water heater sensor has two parts: water level and water temperature, each with two wires and a total of 4 wires.

2. They cannot be connected together randomly, otherwise the water temperature and meter water temperature display will be incorrect.

3. Generally speaking, the square connector from the sensor to the meter has 4 small holes, corresponding to the 4 pins on the meter. Bad connections include: Temperature display.

4. If there is no water level, the temperature will not be displayed. If there is water level, there will be no temperature and there will be no water level display. You can swap the 4 wires repeatedly until the temperature and water level are normal.

Cleaning the gas water heater

1. Shell and filter, for sparkling water. radiators Generally speaking, if it is relatively little dirty, just use a damp cloth to remove the dirt. However, if the stain is large, the user will need to use detergent to clean it thoroughly. After long-term use, a lot of scale and dirt will accumulate on the gas water heater filter. Then the user needs to unscrew the water tap, remove the filter and clean it.

2. Water reservoir. Under normal circumstances, the water tank is an easily clogged part. Next, the user should carefully check whether there is any accumulation of scale, dirt, etc. cleaning. If so, you can use thread to remove it. But if you don't know how to clean it, you can ask professional after-sales maintenance personnel to clean it.

3. The induction needle and the ignition needle. The induction needle and the ignition needle are important factors that affect the temperature of gas water heaters. If you find that the ignition effect is poor in daily life, it may be caused by this. of the appearance of the induction needle or ignition needle problem. The solution is: wipe gently when cleaning, do not use too much force to avoid bending the needle.

4. Gas pipes. Gas lines are usually made of rubber. The obvious downside is that they are very easy to fill with dirt, and many users choose to install them when installing water heaters. is out of the kitchen, the problem of oil stains will become very significant. Users can use detergent to clean oil stains on gas lines.

How to install the Four Seasons solar collector?

Connect four terminals, which mainly distinguish lines.

1. The water level and temperature sensor line is connected to the four "sensor" terminals, from left to right, red, yellow, blue and GND.

2. The pipe temperature sensor wire is connected to the two “pipe temperature” terminals.

3. The solenoid valve terminal is plugged into the "Solenoid valve plug-in terminal".

4. Use the RVV2 × 0.75mm2 power cord for the antifreeze belt line. The red wire is connected to the "L" terminal and the blue wire is connected to the "N" terminal 5. Water supply booster The pump line uses RVV2 × 0.75mm2 power line, the red wire is connected to the terminal. "L" and the blue wire is connected to the corresponding "N" terminal /p>

6. The auxiliary heating system line uses a white RVV3 × 1.5 mm2 jacket. “Electric heating L” terminal, the wireblue is connected to the “Electric heating N” terminal. the yellow and green wires are connected to the ground terminal.

Water level sensor refers to the device that can be connected. An instrument that converts the water level parameter at the measuring point into the corresponding power signal. in real time.

How to connect solar temperature sensor and water level sensor?

Insert the exhaust port sensor into the side of the water tank and keep it vertical. should not be too deep. If it is too deep, the water volume displayed will be less than the actual water capacity. Do not allow the sensor to be tilted horizontally. If the sensor is inserted shallow and tilted horizontally, the water level display will be displayed. be too sensitive. Once the water is filled, it will be full and the water level will be displayed. No water.

The wire and the white wire are for the temperature sensor. The resistancee is between 15K and 18K. normal temperature. The blue wire and red wire are for the water level sensor. When not in water, the resistance is approximately 60K.

Insert the exhaust port sensor into the side of the water tank. and keep it vertical. Do not let the sensor become horizontal. If the sensor is inserted at a shallow depth, the water level will turn green. The blue and red lines are connected to the water level sensor. to judge the quality:

1. The main basis for judging the quality of the heat collecting part is the absorptivity, emissivity and heat transfer rate of vacuum degree

Traditional solar water heaters only Emphasize on heat collection performance and emissivity, but ignore consideration of heat transfer rate. As a result, the hot water in the vacuum tube cannot be quickly transferred to the tankir of water, so that the temperature increases slowly. Question.

2. The heat storage part

There are three criteria: firstly, no leakage, secondly, thermal insulation and thirdly, the key to no leakage is the welding process and materials. Whether anti-corrosion or not, food grade stainless steel is currently generally used as a coating material in the market. The key to insulation is the foaming process of the insulating material and the thickness of the insulating layer. The material must be fully expanded with imported polyurethane and undergo aging treatment. Only in this way can foaming be guaranteed. The holes are small and uniform, and the insulating layer has no gaps.

Detailed information:

Solution:

You can start from two aspects: circuit and material. Since the trigger principlent. of small signal can effectively reduce the electromagnetic force of ions, you can use digital signal mode, you can choose conductive silica gel as the stainless steel protective body, this can prevent.prevent the formation of scale.

Try to use polypropylene and stainless steel materials resistant to high temperatures and corrosion entering the water tank, and use silicone rings to seal areas that need to be sealed . This sealing method is simple, easy to use. and very effective.
