Nanning Sandblasting hose Main impact: The air volume loss of the whole system is too large to meet the air volume requirements, and the power is seriously wasted. 1. If the stainless steel welded air duct system adopts the combined flange air duct, it may be that the seam, flange strip seam and hole seam are not sealed with sealant; The allowance of segment blanking seaming is greater than the specification requirements. 2. No embedded parts are set at the joint of brick structure air duct and metal air duct, or the sealing gap is too large or the joint is not tight. Countermeasures: 1. Button type seaming can be used for medium pressure air duct; Corner seam or joint corner seam shall be used at four corners of high-pressure air duct or clean system air duct. 2. Seams of stainless steel welded air ducts, joints without flange inserts and holes must be sealed with sealing paste to prevent air leakage. 3. During construction, embedded parts shall be set at the junction of brick, structural air duct and metal air duct as required, or the civil engineering unit shall cooperate to block and seal to ensure close connection. During the air duct anti-corrosion treatment, the next anti-corrosion treatment can be carried out after the previous paint is dried; It is strictly forbidden to work without certificate. The duct type air outlet is a central air conditioning terminal air supply system that integrates the functions of air outlet, air supply pipeline, static pressure box, thermal insulation material, air valve, etc. Sandblasting hose Where can I find it? Calculation of air duct size of stainless steel welded air duct: the equal damping method (equal pressure method) is a convenient calculation method, which is suitable for many occasions.
one Nanning Sandblasting hose When using, the talcum powder on the inner wall of the hose must be blown clean to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with acids, alkalis, oils and other organic solvents that can damage the hose. The storage temperature shall be - 15~40 ℃, and the distance from the heat source shall not be less than 1m. 3. According to the national standards, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; The acetylene hose is black, the working pressure vessel is 0.3MPa, the inner diameter of the hose is 8mm, and the outer diameter is 16mm. 4. The gas cutting operation requires a large oxygen output, so the valves of the gas cylinder (or oxygen pipeline) connected to the high pressure end of the oxygen meter should be fully opened to ensure adequate flow and stable pressure. The low pressure gauge has indicated the working pressure, but the pressure drops suddenly when using oxygen. At this time, it is easy to backfire and may backfire into the oxygen hose to cause explosion. 5. Oxygen hose and acetylene hose shall not be mixed or substituted with each other, and oxygen and hose shall not be used to blow away the blockage of acetylene hose. At the same time, it is necessary to check and eliminate the defects such as gas leakage and blockage of the welding torch at any time to prevent the formation of oxygen and acetylene mixture in the hose. It should be pointed out that the hose color specified in the national standard is opposite to that specified in the international standard (ISO) (oxygen hose is black, acetylene hose is red). At the same time, it is different from the original ministerial standard (HG4-605-66) that oxygen hose is red and acetylene hose is green. Before 1966, domestic oxygen hose was black or green and acetylene hose was red. thus Sandblasting hose Where can I find it? It causes inconsistency between the understanding and habits of the supply department and the user, and is easy to cause accidents due to the mixing and substitution of rubber hoses. At present, it should be emphasized that unified understanding and use should be carried out in accordance with the provisions of national standards, and attention should be paid to distinguishing the rubber hoses of imported equipment.
high quality Sandblasting hose The thickness of the seaming plate shall be within the regular range of products of various specifications. If it is less than the thickness, cracks, wrinkles and other defects are likely to occur during seaming; If it is larger than the large thickness, as the square of the plate thickness is proportional, the bending force will significantly increase, which will cause abnormal damage to the forming roller, overloading of the transmission system, and stuffiness. In dust removal system: galvanized air duct can be used for collection and transportation of dust removal device. In the oil smoke exhaust system: there are a lot of oil smoke in restaurants, restaurants and hotel kitchens, which need to be discharged. The galvanized air duct is suitable, strong, economical and practical. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials inside, and the surface is beautiful. In bulk material transportation: pneumatic transportation system, some finer and looser material particles can be transported by galvanized air ducts, with low cost and good effect. In the ventilation system: supply fresh air and exhaust gas, exhaust harmful gas outdoors, and send outdoor fresh air indoors. The strength of stainless steel plate shall be higher than that of ordinary steel plate. Before seaming with stainless steel plate, forming test shall be carried out first to avoid overloading the equipment and causing excessive wear or mechanical trouble. Due to the poor plasticity of the aluminum plate, it is easy to crack during the forming of the seaming. The forming test should also be carried out before construction. At the same time, because the aluminum plate is lack of elasticity, the aluminum plate air duct cannot be subject to snap seaming. After the zinc coating of galvanized air duct is passivated, dyed or coated with light protection agent, Sandblasting hose Where can I find it? It can obviously improve its protection and decoration. The fireproof function of galvanized air duct is mainly reflected in that it is incombustible, but one thing needs to be noted is that whether its insulation layer is burned depends on the material. We suggest that the galvanized air duct should be made of incombustible insulation materials such as centrifugal glass wool.
Nanning Sandblasting hose The entry threshold is low, the industry market is mixed, and small enterprises with small scale, lack of core competitiveness and low technical level can be seen everywhere. Most of these enterprises lack brand awareness, and there are many brand names and unlicensed products. It is difficult to form enterprise influence through brands, and it is more difficult to improve product added value through brands. If the metal hose wants to take the road of high-end, it must improve both inside and outside. A good brand image promotion and influence building can certainly provide a strong driving force for the development of enterprises, but the root of this driving force lies in the high quality of the metal hose products themselves. Tongfeng Metal Hose said that in the future, domestic metal hose products will focus on high precision, high efficiency, high firmness, multi-function, multi specification, multi variety standardization, serialization and generalization to show their characteristics. One of the main reasons why China's metal hoses have been in the low-end state for a long time is the lack of independent research and development of products. On the one hand, the homogenization competition is serious. In order to win consumers, metal hose enterprises have long focused on low-cost competition and low price shopping. As a result, many enterprises only focus on the production and marketing of low-end products, ignoring the upgrading and innovation of product technology. on the other hand, Sandblasting hose Where can I find it? ZHUANLI's weak awareness of protection and the serious phenomenon of technology plagiarism and infringement in the industry make the technology cost invested by many enterprises more than worth the cost, which has seriously hit the enthusiasm of metal hose enterprises for innovation.
high quality Sandblasting hose It will burst for a long time due to frequent and severe pressure shocks. This situation is usually not caused by excessive static pressure, but is related to the strength and frequency of pressure shock. During the operation of construction machinery, the oil pressure in the oil resistant hose will rise or fall repeatedly, and then it will form frequent pressure shocks to the oil pipe, causing the oil seal of each part to become more damaged, the oil resistant hose will bubble and break, and the pipe joint will become loose and leak. Therefore, in the process of operation, the valve rod should not be pulled too hard, and it needs to be gentle. The application temperature of the oil in the oil resistant rubber hose is too high, resulting in aging and bursting of the rubber hose. During the operation of construction machinery, the hydraulic system will cause the oil to become hot due to power failure, and the influence of external temperature (especially in summer) will cause the oil temperature to rise sharply. The higher the oiling temperature is, the easier the rubber hose ages, the worse the elasticity is, the lower the strength and sealing function are, and the oil resistant hose will burst quickly. Therefore, Sandblasting hose Where can I find it? During operation, when the temperature rise of the hydraulic system is too high or too fast, the causes should be found and eliminated in time. Necessary cooling measures shall be taken for summer operation, especially continuous operation.
