one Shenyang Air compression 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 Air compression hose company 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.
Shenyang Air compression hose 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, 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; 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 substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first 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. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Air compression hose company When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.
Air compression hose company Precautions ① The acid and alkali resistant rubber hose used shall not only be oil resistant, but also be pressure resistant, heat resistant, cold resistant, wear resistant and aging resistant. ② The rubber hose should not be too long or too short, generally 1.4 meters. ③ The interface is tight and can be fastened with thin iron wire or clip to prevent falling off and air leakage. ④ It is forbidden to pull acid and alkali resistant rubber hose from one room to another or through walls, floors and floors to prevent accidents caused by rubber hose breaking and falling off. ⑤) The acid and alkali resistant rubber hose should be placed in a place where it can be seen frequently, so that it is easy to detect leakage. Check whether the rubber hose leaks after each bottle change. ⑥ Do not replace acid and alkali resistant rubber hose with universal rubber hose. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose; The cloth clamping hose needs to use a molding machine that wraps the adhesive tape on the inner adhesive layer; When forming the suction hose, first wrap the metal spiral wire and then wrap the inner rubber; Special fabric knitting machine or winding machine shall be used for knitting and winding hose; Knitting machine is required for knitting hose. Shenyang Air compression hose The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The manufacturer of acid and alkali resistant rubber hose said that the processing method of the skeleton layer and the forming equipment of the rubber hose are different for different structures and different skeletons.
Let's take a look today Shenyang Air compression hose How should the maintenance work be done? Firstly, the thickness of galvanized air duct splice plate shall be within the range specified in various specifications. If it is less than the thickness, it is easy to have defects such as cracking and wrinkling due to significant increase of bending force, abnormal damage of forming roll, overload of transmission system, boring, etc. Secondly, in the dedusting system: galvanized air ducts can be used for the collection and transportation of dedusting devices. In terms of air exhaust system: there is a large amount of smoke in the dining room, dining room and hotel kitchen, which needs air exhaust. The galvanized pipe is more appropriate, with good strength, economy and practicality. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials, and the surface is beautiful. In bulk material transportation: in the pneumatic conveying system, some materials with fine loose particles can be transported by galvanized pipes, which has low cost and good effect. In the ventilation system: fresh air is supplied and discharged, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. The strength of stainless steel plate is greater than that of ordinary steel plate. When stainless steel plate is used for seaming, first of all, a forming test should be carried out to avoid overloading of equipment and excessive wear or mechanical problems. Due to the poor plasticity of aluminum plate, it is easy to crack when biting into forming. Forming test shall be conducted before construction. The last point is that the protection and decoration of the galvanized layer of the galvanized air duct can be significantly improved after passivation treatment, dyeing or brushing light protective agent. and Shenyang Air compression hose The fire prevention function of is mainly reflected in that it is nonflammable, but it should be noted that whether the insulation layer is burned depends on the material. We recommend that galvanized air duct materials use nonflammable insulation materials such as centrifugal glass wool.
We all know Air compression hose company The noise pollution in industrial production is very serious, and noise pollution is also an important factor affecting workers' enthusiasm for production. Ball mills were once a major source of noise in mining equipment. In order to reduce the noise generated by ball mills, protect the physical and mental health of workers, improve workers' enthusiasm for production, and create greater profits for the company, Through the efforts and research of domestic and foreign industry experts, the ball mill liner has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber liner and the manganese steel liner of the ball mill is far less than the manganese steel liner when the technical parameters are up to standard. According to the data provided by the noise monitoring station and the concentrator, We analyzed the noise intensity and the economic benefits: the domestic ND2 precision sound level meter and octave filter were used for detection, and the sound level meter was calibrated by the provincial sound level meter measurement and verification station; There is no sound insulation room in the ball mill workshop. The monitoring points are arranged according to the position of the ball mill and the flow of workers to observe the mechanical operation, 2m away from the sound source. One monitoring point is respectively set on the left and right of the east and west of the workshop and in the middle of the two ball mills. The measurement method is in accordance with the Noise Detection Specification for Industrial Enterprises. As the noise in the workshop is continuous and steady, sound level A is used as the evaluation basis. The rubber lining plate is manufactured by Hainan Rubber Lining Plate Factory according to the ball mill shell structure and the original manganese steel lining plate specification (1.4mx0.74mX0.07m). Shenyang Air compression hose First, take out the manganese steel lining plate in the ball mill barrel, and then install the rubber lining plate in the barrel in turn (front and back). Each ball mill is installed with 48 pieces. First, use the pressure strip to compress, and then use the screws to fix the rubber lining plate on the ball mill barrel, so as to prevent falling off when rotating. The noise intensity of the ball mill workshop with manganese steel liner is 94-103dB (A), while the noise intensity of the ball mill workshop with rubber liner is 87-92dB (A), and the noise reduction difference is 7-11dB (A). The rubber liner has good noise reduction effect.
Many people don't know much about spiral tube. In fact high quality Air compression hose It is very extensive. Spiral air duct is mainly used to connect the two places for ventilation. Spiral air ducts (stainless steel and galvanized iron sheet) are widely used in the market. Spiral air duct market is generally divided into three categories according to material: galvanized spiral air duct, stainless steel spiral air duct and composite spiral air duct. Among them, the stainless steel air duct has good quality and strong applicability, but its price is high. The return air duct of purification system, central air conditioning ventilation duct, industrial air supply and exhaust duct, environmental protection system suction and exhaust duct, mine gas drainage duct, mine coating duct, etc. The spiral duct is first used for ventilation and cooling, which belongs to the category of air duct. It is named according to its purpose, but it can also be used in other places, even for drainage, drainage or as a container, which cannot be called a pipe. Named according to the structure, it should be called spiral grooved thin-walled tube, because it is mainly made of metal, also called spiral grooved metal tube. According to the material name, there may be several names: galvanized (any zinc) (galvanized) (iron), spiral pipe, stainless steel spiral pipe (stainless steel acid resistant steel), aluminum (aluminum) spiral pipe, or in order to distinguish from the existing acid resistant stainless steel pipe, Air compression hose company It can be called ultra-thin stainless steel pipe, because it can use 0.3mm or even thinner to roll stainless steel strip.
