All kinds of material Brazed Radiator use range and installation maintenance precautions
The application scope and installation maintenance of the inner cavity non-sand-cast-iron fine casting Brazed Radiator
Using rare earth cast iron material, the product structure is more compact and beautiful, the metal thermal strength can be improved significantly and the pressure capacity can reach 1.0mpa. The inner cavity is free of sand, so it is suitable for thermal measurement and temperature control technical requirements. Surface electrostatic spraying, smooth and beautiful, the decoration performance has changed qualitatively, yiyu Ming suit, do not need to cover. Suitable for the current hot water heating system and water quality in our country, it can also be used in the steam heating system. It is widely used in the non-heating season.
Application scope and installation maintenance of copper aluminum composite and copper tube
Light weight, metal thermal intensity is high, suitable for hot water heating system, heat medium temperature is not higher than 95 ℃, chloride (Cl -), sulfuric acid root ion, respectively (SO42 - no greater than 100 mg/L. Work pressure is less than 1.0 Mpa. The Brazed Radiator should be installed on the solid wall, the bottom of the Brazed Radiator is 100 mm ~ 150mm. Brazed Radiator should be installed on windowsill or sills side. Non-heating season, full water maintenance can extend the life of Brazed Radiators; When indoor temperature is lower than 0 ℃, should be the Brazed Radiator in the inland waters emptying, so as to avoid frost crack.
3. Thin-wall (1.2 or less than 1.5) steel tube Brazed Radiator application scope and installation and maintenance precautions
Brazed Radiator compound by steel tube, steel pipe inner cavity process to prevent corrosion, good heat dissipation performance, metal thermal intensity high, adornment effect is good, with the parent, there is no need to ladle cover, suitable for installation for room temperature control temperature control valve. Brazing steel pipe heating radiator is only applicable to closed hot water heating system, temperature is not more than 120 ℃, circulating water system and hydrating the oxygen content of 0.1 g/L or less, and the PH = 10-12, otherwise prone to severe oxygen corrosion and electrochemical corrosion leakage phenomenon, reduce the service life of the Brazed Radiator. It is not suitable for steam direct heating system. It is forbidden to use geothermal, industrial waste heat and thermal power plant cooling water as heat source to connect directly with the pyjie series steel Brazed Radiator. In the heating system, the connection pipe is forbidden to use the plastic pipe without the resistance layer, the Brazed Radiator should be installed on the solid wall, the bottom of the Brazed Radiator is 100 mm ~ 150mm. Brazed Radiator should be installed on windowsill or sills side. During the non-heating season, the water should be filled with water. When indoor temperature is lower than 0 ℃, should be the Brazed Radiator in the inland waters emptying, so as to avoid frost crack. Work pressure is less than or less than 1.0 Mpa. Steel thick-walled Brazed Radiators are not subject to this limitation.
The hot water system is shut down, which means the water is constantly circulating through the pipe into the boiler. The newer units have many areas, and two water pipes are connected to each area: one heated water to the room, and the other to return the colder water to the boiler to reheat it. In the older single-tube system, hot water flows out of the room and then comes back to the same tube of boilers. The last room on the circuit was never as warm as the first one.
To maintain the system, lubricate the circulation pump motor. Use light oil, such as 3 and 1, and pour it into the oil cup. In the fall and throughout the heating season, you also need to discharge or remove the radiator that has no automatic cleaning system. To discharge the Brazed Radiator and empty the boiler, follow the instructions:
Open the soldering radiator and the valve on the convector to vent the air. Stay open until the water comes out. Be prepared to hold water in a bucket or container. There are also friends asking whether there is a difference between the radiator and henan radiator, which will close the valve next time.
Don't forget to remove the boilers and remove the rust and minerals. Read the manufacturer's instructions and follow these steps:
Turn off the power and water. Instead of the old cast iron Brazed Radiator, today's units have separate or skirted convection. They are smaller, more efficient, look better than their ancestors, and provide the same heat for all rooms. The disadvantage of hydrothermal or hot water is that there is no central air due to the lack of pipeline work. Insert the end of the garden hose into the boiler drain cock.
