What problems should be paid attention to when using the radiator?Date：2018-08-29 11:15:27 Browse :
Everyone usually uses the radiator, the most concerned issue, in addition to the heating effect and heating costs, the most concerned about the safety of the radiator. In particular, some radiator manufacturers now pursue the interests blindly, and the quality of the products is lax, resulting in certain safety hazards in the radiators, and even the phenomenon of radiator cracking.
So, is the use of heating safe? Will the radiator burn the child? Will the radiator cause an explosion?
Question 1: Will the temperature of the radiator burn the child?
A: Generally speaking, the surface temperature of the radiator is only about 45 degrees. We feel very hot when we touch it by hand. As long as it is not touched by the radiator for a long time, it will not be burnt. Even the skin of a child does not cause any harm.
Question 2: Is the paint surface on the surface of the radiator toxic?
A: There are some small brand radiator manufacturers, which are too quick and quick. For the painting of the surface of the radiator, there is no standard. When heating the radiator in winter, the harmful substances of the paint, such as formaldehyde, will be released continuously. In and out, it causes very large pollution to the home environment.
It is recommended that when choosing a radiator, it is best to carefully understand the paint surface of the radiator to ensure environmental protection. Generally speaking, the radiators produced by regular manufacturers have strict regulations on production technology, health and environmental protection, etc., just like the Sunrat HVAC, which uses the environmentally friendly plastic powder for Aksu radiator, zero formaldehyde, no pollution, Consumers don't have to worry about the toxic problem of the radiator paint.
Question 3: Will the radiator leak or explode?
A: The radiators used in our homes generally have a pressure limit of 1.0-1.2MPA, while the actual heating pressure of the home heating is 0.4-0.8MPa. Generally, there will be no water leakage or bursting. For example, the Sunrad radiator has undergone 5 leak pressure tests before leaving the factory. The test pressure of 1.5MPa is much higher than the actual heating pressure of 0.5-0.8MPa, so that each radiator will not leak. Therefore, as long as it is a regular manufacturer that passes the qualified radiator and is correctly and reasonably used, there will be no water leakage or explosion.
Question 4: Is the water in the heating pipe poisonous? Can it be used?
Answer: The heat of the heating is realized by the hot water circulation in the heating system. If the water in the heating pipe is taken privately, it is easy to cause the heating system to fail to ensure the heating due to the lack of water, which will affect the heating effect. It caused a heat accident. In addition, the heating water contains a large amount of chemical reagents, which are used for softening of water and maintenance of pipes. Heating water is used for domestic water, which may be harmful to health.
Question 5: The radiator is hung on the wall. Will it fall down and hurt people?
Everyone knows that the radiator is made of metal such as steel and copper, which is very heavy. In order not to take up space, to maintain indoor beauty, most families will choose vertical installation of radiators, which involves the problem of radiator accessories, such as the number of expansion nails, the number of hooks and the height and width of the radiator are closely related, and their quality The pros and cons are also important factors in the safety of the installation. We recommend selecting the accessories supplied by the original radiator and the professional installation company to install the radiator.
All in all, if we are buying a regular manufacturer's radiator, it will not be safe to install and use according to the relevant specifications of the radiator heating installation.
However, the following details of the safety of the radiators should be kept in mind:
One. The support legs of the radiator cannot be sealed with cement
During the heating process, the pipe is thermally expanded and contracted due to temperature changes. The radiator itself should be displaced. If the support leg of the radiator is sealed with cement, the radiator cannot be displaced, and the connection point of the radiator of the radiator is subject to a large pulling force. To a certain extent, the pipe is damaged. This caused a water run accident, and such phenomena have occurred frequently during the heating process in previous years.
two. It is best not to have a covering on the radiator
Together with the "packaging" cooling system, it first affects the heat conduction, convection and radiation effects, thus affecting the heating effect. After the experiment, there is "packaging" about three degrees Celsius lower than the "packaging" room temperature. In addition, failure to detect heating facilities and inconvenience in inspection and maintenance cannot be found in time. If the interior is to be renovated, it is convenient to repair the heating facilities. An overall mobile trim cover is recommended.
three. When the radiator is pressurized and tested, it is best to keep people in the house.
If it is a new residential area, the residential property needs to do the pipeline inspection work, check whether the valve is loose, slippery, the internal pipe network insulation is good or bad, whether the various instruments are malfunctioning, etc. If you encounter technical difficulties, you can give the heating company Timely feedback.
In the old open-plan community, it is best to keep people in the home, and run, run, drip, and leak. It can quickly shut down the water supply and return valves, move the appliances to prevent power leakage and hurt people, and quickly notify the heating department to repair.
In addition, the heating department also reminded the public that if there is air in the heating pipe, the exhaust valve may be opened by the air pressure during the pressurized test. In this case, the public may first plug the valve with a towel and then look for it. A round chopsticks is blocked to prevent burns.
4. Heating facilities cannot be modified without authorization
The indoor heating system is designed, constructed and installed strictly according to technical specifications. Changing the heating facilities without authorization will often change the operating conditions of the heating system, which will easily lead to hydraulic imbalance and affect the heating effect.
In addition, the self-refurbishment of heating facilities, due to the lack of necessary construction and installation tools and experience, it is easy to damage the heating facilities, when the equipment is filled with water, it is prone to run and leak, affecting normal heating, and serious damage to property, to themselves and others. Cause economic losses.
If the user needs to modify the indoor heating facilities for special reasons, he may apply to the heating unit. If the heating unit confirms that the modification will not affect the heating effect, the heating unit may make changes, and the user shall bear the relevant expenses.
