How to install correctly Xuzhou Sandblasting hose ？ In the fire smoke exhaust pipe system, the airport and air valve must use non fuel, and the thickness of citizen flue and galvanized ventilation pipe should be improperly used. The high-pressure system should be selected according to the national code GB50243. When the fire smoke exhaust fan is installed on the roof, certain maintenance measures should be taken. The exposed power line must be threaded through the conduit, and the conduit material should be combined with the metal hose or Capelli and duck neck equipment to make it curved. The fire fighting system and equipment lines must be fixed with special clamps to avoid falling. Stainless steel air duct and ventilation equipment shall be made of three fabric flame retardant materials with soft connection. It is suggested that the length should be 15-30cm, and the electrical interpenetration should be completed. Bolts require the same length. The three main bodies should be grounded, ventilation equipment, and equipment and devices between dynamic loads should be equipped with shock absorption measures. When Sandblasting hose Where can I find it? Box type pipe fittings should not be used for changing direction, variable diameter, branch road, or junction, but the wind speed of box section should not exceed 1.5m/s for air distribution and static pressure box when necessary; It is advisable to have 5-10 times the pipe diameter between conduit pipes. The length of expandable metal pipes or non-metallic soft links should not exceed 2 meters. There should be no disintegration and dead corners. During the installation process, when the length of pipe elbows and straight pipes exceeds 20 meters, add anti impact frame open room exhaust fans and add or subtract supports.
Xuzhou Sandblasting 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. Sandblasting hose Where can I find it? 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.
Xuzhou Sandblasting hose It is a kind of hose that can be used for sand pumping and sand suction produced with high abrasion resistant rubber. It is often used in sand blasting industry, cement, steel, minerals and other industries, but it is mainly used in river dredging, slurry transportation in mines, sand digging and sand taking and other industries to transport sharp granular solids or solid-liquid mixtures. Its product structure is composed of high wear-resistant layer, reinforced water pipe layer, skeleton steel wire and outer rubber. Today, Myers will introduce the application field of wear-resistant sand absorption rubber pipe. When the wear-resistant sand suction rubber pipe is applied in the mine pit, it is necessary to set a floating boat equipped with a sand pump in the mine pit, and use the floating sand suction rubber pipe to connect with the sand pump. The floating boat will float up and down with the rise and fall of the water level. It is required that the pipe body has good flexibility and good tear resistance and bending resistance. The offshore pipeline is connected by non floating sand suction hose until the pulp transportation destination. The overall pipeline is divided into two parts, one for surface use and the other for onshore use. The main raw material of these two kinds of hoses is high abrasion and corrosion resistant rubber, and cord reinforcement layer and steel wire skeleton layer are added in the pipe wall to ensure the pressure resistance and tear resistance of the hose. The connection mode is vulcanized flange connection, that is, the flange and the hose are a whole, so there is no need to worry about the flange falling off. Floating sand suction hose used on the water surface. This kind of hose is required to float on the water surface. Due to the large drop of the mine (100 meters) and the long conveying distance Sandblasting hose Where can I find it? The hose shall have high pressure resistance, and the design pressure is 25 kg/cm2 according to the calculation. It should be considered that the floating ship will move up and down with the rise and fall of the water level and the wave will cause lateral displacement. Its internal structure is the same as the sand suction hose used offshore, except that a floating body is installed outside the hose.
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 Xuzhou Sandblasting 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, Sandblasting hose Where can I find it? 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.
People buy in daily life production Sandblasting hose Take it home for installation. It is obviously installed very well, but the spiral air duct will become loose for a long time, which gives most users a headache. So what is the problem with spiral air duct reinforcement? This is of course necessary. The following manufacturer of galvanized spiral air duct will give you a detailed introduction. 1. Reinforcement measures shall be taken for circular pipes (excluding spiral pipes) with a diameter greater than or equal to 80 mm, a section length greater than 1250 mm or a total area greater than 4 ㎡; 2. The side length of rectangular air duct is more than 630 mm, the length of pipeline insulation side is more than 800 mm, the section length is more than 1250 mm, or the plane area of one side of low pressure pipeline is more than 1.2 m2, and that of medium and high pressure pipeline is more than 1.0 m2, so reinforcement measures should be taken; 3. For reinforcement of irregular oval pipes, the reinforcement method of rectangular pipes shall be referred to. The spiral air duct manufacturer Hongyuansheng Electromechanical also has something to say: the reinforcement of galvanized air duct non-metallic air duct should also meet the following requirements: when the diameter or side length of the rigid PVC pipe is greater than 500 mm, the connection between the pipe and the flange should be equipped with stiffening plates, and the spacing should not be greater than 450 mm. The reinforcement of organic and inorganic FRP pipes shall be made of the same materials with the same anti-corrosion performance as the pipes themselves. Sandblasting hose Where can I find it? The manufacture of rectangular pipe elbows shall generally adopt concentric arc elbows with the curvature radius of the length inside and outside the plane. When other forms of elbow are used, and the plane length is more than 500 mm, the elbow deflector shall be set.
