In the home, when we go to the winter, we need to use the wall-hung boiler for heating. But our friends who are heating this wall-hung boiler are not very familiar with it. So what is the way it works in the way of heating? What are some of the shopping techniques for this wall-hung boiler heating? And what everyone else knows is that our wall-hung boiler heating precautions are flawed.
First, the working principle of wall-hung boiler heating
1. After the boiler is started, after the system pressure is normal, the pump starts to push the heating medium water to flow, open the water flow switch or the water flow sensor, output the water flow signal (switching signal or pulse signal) to the main controller, and the main controller receives the water flow. After the signal, start the fan to clean before, and check whether the various safety devices are normal. Under the normal conditions of various safety devices, ignite and then open the first and second valves respectively.
2. The gas enters the burner to ignite the gas under the action of the electric spark for combustion (in the process of ignition, the fan is generally operated at half speed or powered off by inertia, and after the ignition is started, the fan speed is determined according to the amount of gas. The gas proportional valve model is used. The proportional valve divides the ignition current, the minimum current and the maximum current, and can be adjusted separately. The flame is normally burned by the ion flame technology, and the heating medium is radiated into the air through the radiator or radiated to achieve heating. the goal of. After the set heating temperature is reached, the flame is turned off and enters the standby state. This cycle is repeated.
3, heating / hot water dual-use gas boiler operating principle Description: Connect the heating and return water interface, heating hot water interface, cold water inlet interface, sanitary hot water outlet, gas inlet interface, plug in the power plug, open the gas supply valve . Unscrew the water supply valve and open the cold water inlet valve to fill the heating pipe system. When the water filling pressure is about 0.2MPa, close the water supply valve and press the “ON/OFF†switch on the adjustment panel in the “ON†position. Control system First, check whether the heating system pressure is between 0.1 MPa and 0.3 MPa. If it is normal, the dual-purpose wall-hung boiler enters the standby state.
Second, the wall-mounted furnace heating purchase skills
1, look at the brand
In general, when you choose a good brand, you choose security, choose peace of mind, and choose a service. When manufacturers sell their products, they can spit out lotus, and they promise everything, but there are not many that can really be promised. Because there is not enough capacity and financial resources to support after-sales service, there is no guarantee that the accessories will be supplied in a timely manner. Most of the users trust the original imported wall-hung boilers. The original imported wall-hung boilers must have customs reports. Manufacturers are required to provide raw materials for customs declarations, purchase invoices, and identify with local authorities whether they are genuine imported products. Avoid spending money on it! In addition, you must choose a wall-hung boiler with a product insurance policy. The manufacturer is responsible for the accident.
2, look at the power
The same brand has a variety of power options, the selection of power is large, wasting money, wasting energy. The power selected is small, and the capital and energy waste is small, but it does not meet the requirements for use. Look at the energy efficiency label of the wall-hung boiler. The best energy-efficient wall-hung boiler is the secondary product. Some wall-mounted boilers can't reach the third level, and there is no energy efficiency label. Choose according to your own housing area. Generally, the heating power required per square meter is between 120w and 180w, and it varies according to the room type, structure and building materials. Therefore, before you choose the heating furnace, you should first seek the advice of the service provider. Your house is roughly calculated by which power, and then an approximate overall power is measured. Recommend a formula to calculate the approximate power: the building area of ​​the house × 65% × 150w.
Third, the wall hanging furnace heating precautions
1. The pressure must not be too high. 1.2 to 1.5 is the most suitable range. If it exceeds the limit, the service life of the sealing parts will be reduced. If the pressure is too small, the phenomenon will not start. The solution is to open the air release valve and open the water. Water switch to add water.
2, water temperature bath and dishwashing, we are using the hot water function of the wall-hung boiler. Everyone is used to feeling that when the water is hot, it is a big mistake. The hot water in the wall-hung boiler is not directly heated, so we change the pressure in the circulating hot system while adding cold water.
3, clean, permanent, we will find that the water output of the faucet is getting smaller and smaller, how is it going? The problem may appear on the faucet, the solution is very simple, that is, the faucet filter is removed, the impurities are removed. That's it.
The above is the introduction of some working principles of our wall-hung boiler heating, as well as the precautions for the use of wall-hung boiler heating, then we must also consider how the market buys this wall-hung boiler for heating, so Xiaobian will tell us about the heating technology of wall-mounted boilers. Everyone. Our decoration home network has other decorative information, I believe it will bring a lot of benefits to friends.
