Air duct mainly refers to the ventilation duct of the central air-conditioning system, which is often ignored, but it is an important part of the air-conditioning system. Wuhan Cord hose What are the regulations for welding air ducts? Gongfa HVAC is a manufacturer dedicated to the production of air ducts, which has been recognized and supported by the majority of users for many years. 1、 The welding regulations of carbon steel plate air duct are as follows: 1. The carbon steel plate air duct should be welded by DC welder. Introduction to welding air duct If AC welding machine is used for welding, a vibrator must be added to reduce excitation and stabilize the arc. When welding steel plates, the arc is unstable, which can lead to deterioration of weld quality. 2. Before welding, remove the dirt, oil stain and rust at the welding port; When spot welding or continuous welding is used, the oxide shall also be removed. The butt joint shall be kept with the minimum gap, and the overlap at the manual spot welding location shall be removed in time. After welding, the electrode slag and residual welding wire in the weld and its surrounding area shall be removed in time. 2、 The welding regulations of stainless steel air duct are as follows: 1. Before welding the air duct, remove the grease and dirt in the weld area to prevent pores and sand holes in the weld. Cleaning can be carried out with gasoline, acetone, etc. When welding stainless steel plates by electric arc welding, the surfaces on both sides of the weld should be coated with white ash, Wuhan Cord hose To avoid welding slag splashes adhering to the surface of the plate. 2. After welding, attention shall be paid to removing the slag at the weld, brushing the metal luster with a copper wire brush, pickling with 10% nitric acid solution, and then cleaning with hot water.
1. Mutual wear of rubber lining plate and steel ball of ball mill: both the rubber lining plate and steel ball of ball mill are vulnerable parts. During grinding, the steel ball and material of ball mill do throw line falling movement in the barrel Wuhan Cord hose It will collide with steel balls and materials and cause friction. In continuous operation, the rubber lining plate and steel ball of ball mill will be severely worn, which is directly related to the hardness of materials. The greater the hardness of the material, the faster the abrasion speed of the rubber lining plate and steel ball of the ball mill, which may cause equipment damage or even safety accidents in serious cases. In addition, it is also related to the ball of the ball mill. The size and quantity of the ball will affect the service life of the rubber lining plate of the ball mill. If the ball mill is in operation, increasing the amount of steel balls or filling steel balls with larger diameters will increase the wear of the rubber lining plate of the ball mill. 2. The heat treatment process of the rubber lining plate of the ball mill is unreasonable: the unreasonable heat treatment of the rubber lining plate of the ball mill will not only increase the wear of the lining plate, but also affect the yield strength of the lining plate, resulting in the fracture of the bolt of the ball mill under the large shear force. In the actual operation, the staff lacked the understanding of the lining plate material and the heat treatment processing of the ball mill rubber lining plate was insufficient, so the strengthening effect of the ball mill rubber lining plate was not in place and the strength was low. When impacted by steel balls and materials, Cord hose Price Plastic deformation often occurs. 3. The material of the rubber lining plate of the ball mill is unreasonable: the material of the rubber lining plate of the ball mill and its heat treatment process are the key to determine the mechanical performance of the lining plate. If the material of the lining plate is not properly selected, its fatigue strength and life will be greatly reduced, which will not meet the requirements of the ball mill, or even plastic deformation or bulge will occur.
Ventilation pipes on ships are generally made of galvanized iron sheet high quality Cord hose This kind of air duct is generally made by hand, and the production efficiency is low. Later, circular spiral air ducts made by machines greatly improved the production efficiency of air ducts and the quality of air ducts, which were widely used on civilian ships. However, for military ships with very strict height restrictions, circular air ducts obviously occupied more height than rectangular air ducts, which limited the promotion and use of circular spiral air ducts on ships. In the 1980s, 708 Research Institute, the Military Representative Office of Navy Garrison 426 Factory and Dalian Bohai Air Conditioning Auxiliary Factory jointly successfully trial produced the flat spiral air duct. It combines the advantages of the circular spiral air duct and the rectangular air duct. It is the third generation of air duct for ships, which is welcomed by the ship design department and has achieved good results after many ship use. The structure of the spiral air duct is the same as the round spiral air duct. It is also formed by rolling galvanized iron sheet on a special pipe coiler. Therefore, it can be produced mechanically, and the inner surface of the air duct is flat and smooth. The utilization rate of materials is also high. The thickness of galvanized iron sheet is generally 0.6mm. Although it is 0.75~slightly thinner than the commonly used rectangular air duct iron sheet, its rigidity is higher than that of rectangular air duct due to the reinforcement effect of spiral undercut. There are two types of flat spiral air duct: non adiabatic and pre adiabatic. Non adiabatic type is applicable to air conditioning ducts with simple mechanical ventilation, natural ventilation and external insulation. Wuhan Cord hose There are two types, one is air layer insulation, that is, there is 12.5~thick air layer between the inner pipe and the outer pipe. The other is that the inner and outer pipes are filled with thermal insulation materials rock wool or ultra-fine glass wool to become good thermal insulation air conditioning ducts.
