Xiaobian takes you to learn about the types, purchases and installations of radiators!!
One: the classification and characteristics of the radiator
The radiator can be divided into three types: iron radiator, aluminum radiator and steel radiator:
1. Cast iron radiator: The old cast iron radiator will be gradually eliminated by the market because of its low pressure, large volume, rough shape, high energy consumption and many other insurmountable disadvantages. At present, the cast iron radiator industry has accelerated the pace of developing new products, and gradually developed a new product with beautiful appearance, energy saving and material saving. The cast iron radiator will be available in a new image.
2, steel radiator: according to the style, there are two main types of plate and column. The steel column radiator has won the favor of many consumers with its rich color and beautiful appearance. Customers who purchase steel radiators should consider whether they are matched with the heating system of the community. Consumers who use open heating systems should carefully choose steel radiators because steel radiators are prone to oxidative corrosion when exposed to oxygen. And the oxygen content in the water has strict requirements, and all of them need to be maintained in the main system after the heating period. If the maintenance is not good, the radiator will quickly replenish the corrosion and eventually the radiator leaks.
3, aluminum radiator: mainly high-pressure cast aluminum and tensile aluminum alloy welding. The main advantages are: aluminum has good heat dissipation and energy saving features are very obvious. In the same room, if the same size of radiator is used, the number of aluminum casts is less than that of steel; aluminum has good oxidation and corrosion resistance. Without adding any additives, the principle is that once the aluminum encounters oxygen in the air, it forms an oxide film which is both tough and dense, preventing further corrosion of the bulk material.
Radiator quality identification:
1. Whether the surface paint of the radiator is shiny, whether the color is pure and bright; whether the surface solder joint is obvious, you can use the hand to touch the surface to judge whether it is smooth.
2, ask the thickness of the plate, the thickness of the plate directly affects the service life of the radiator, usually should be 1.25mm, but some manufacturers in order to cut corners, the actual thickness of the plate is thinner than its claim, the simplest The method of identification is to lift a group of heating 掂掂 its weight, you can try different types of heating but the same specifications of the heating, who is light and natural, there will be a number.
Two: radiator purchase considerations
Precautions when purchasing a radiator:
1. Home market where consumer satisfaction or after-sales service is trustworthy
2, to shop around, for the same style, the same brand of goods, from the quality, price, service and other aspects of comprehensive consideration
3. Security. The safety and performance of the radiator is the most important. There are many factors involved in the safety performance, and the working pressure of the radiator is very important.
4. Selection. When selecting the type, it should be clear that the inlet and outlet water temperature, room temperature, room heat load, window sill height and width, and the heating system used by the home are single or double pipe.
5. Does the manufacturer have many years of experience in the production of heating equipment, and whether the products meet the national standards.
6, whether it can provide good after-sales service, whether there is a professional plumbing measurement installation team.
7, is the choice of plate or column radiator. For small space, such as the bathroom, you can choose a column radiator, because it uses a wall-mounted type, you can save indoor space; you can also hang a towel or bake small clothes on the horizontal column; for a larger room, it is recommended The purchase of plate radiators, because of the internal increase of the convection plate, radiation and convection heat dissipation mode can achieve the best heat dissipation effect in the shortest time, and can save a lot of energy.
8. There is no practical relationship between the amount of heat dissipation and the size of the inlet and outlet pipes. The main reason is to see the flow rate of water in the heating. As long as the water flow rate can reach the standard, the heat dissipation will also be guaranteed. It is wrong to think that the size of the inlet and outlet of the heating water pipe is large and the heat dissipation performance is good.
9. The name, specification, quantity, price and amount of the radiator must be indicated on the invoice and contract.
10. Know the name, address, contact person and telephone number of the organizer and manufacturer so that the quality problem can be solved in time.
Three: Installation notes for the radiator:
1. The installation position of the radiator is inconsistent. Failure to follow the drawings or to measure the inaccuracy of the furnace hook card size.
2. The asbestos rubber mat of the radiator pair is too thick, and the outer diameter of the gasket protrudes to the surface of the mouth. The reason is that when the thickness of the gasket exceeds 1.5 mm (column type) or the double pad is used, the outer diameter of the gasket is too large, and a qualified gasket should be used; the thickness of the flange flange gasket should not exceed 3 mm.
3. The radiator installation is not stable. This is because the hook arc does not match the heat sink or the touch is not tight, the hook and the furnace card are not strong, and the column radiator legs are not solid, and measures should be taken to remedy the problem.
4, the furnace hook furnace card is not strong. The hole in the planting is too shallow, the cleaning in the hole is not clean, the cement label is too low or the mortar is not filled and it is not strong; when the planting is not correct or the position is not accurate, the furnace hook and the furnace card are not correct.
5, the furnace block, the furnace to the heart of the buckle too little. Because the thread is too tight, the thread should be selected before installation.
6. The number of column-type radiator legs installed on the floor is incorrect and the position is uneven. Two leg pieces are required for 14 pieces or less, three leg pieces are required for 15 to 24 pieces, and four leg pieces are installed for 25 pieces or more, and the leg pieces are evenly distributed.
7. More than 20 cast iron column radiators shall be fixed with ribs, and the ribs shall be made of φ10 round steel. The foreigner of the sash shall not exceed one nut thickness.
8. The height of the hanging radiator from the ground is determined according to the design requirements. When the design is not required, it is generally not less than 150mm, but the upper surface of the mounted radiator shall not be higher than the elevation of the window sill.
9. When the round-wing radiator is installed, the airfoil should be installed downward or toward the wall to avoid affecting the appearance. Do not use the wrong center and eccentric flanges to ensure that water or condensate can flow out of the radiator smoothly.
10. It is necessary to cooperate with the civil construction to ensure the accuracy of the reserved position of the riser and the elevation of the ground to avoid the difficulty in installing the radiator and avoid the phenomenon of sawing, lying and padding.
