production Oil resistant 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, Oil resistant hose Price 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.

Xiamen Oil resistant 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 Oil resistant hose Price 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.

Xiamen Oil resistant hose With the continuous updating of technology, the products are also developing in the continuous updating. At present, the inspection requirements of rubber hose are also improved compared with the previous ones. The inspection index of ultra-high pressure hose shall meet the following index requirements according to the requirements of the Safety Code for High Pressure Water Jet Cleaning Operation: 1) The bursting pressure shall be more than 2.5 times of the working pressure. 2) The test pressure shall be 1.5 times of the working pressure, and the pressure shall be kept for more than 2 minutes without damage. 3) Pulse pressure shall be within the range from zero to working pressure, and 50000 pressure pulses shall be free of damage; The pulse frequency is 15 times/min when the working pressure is 1000-2800bar, and 110 times/min when the pressure is above 2800bar. Since high-pressure cleaning machine has been widely used in all walks of life, and the working condition of high-pressure hose is relatively the worst, we must pay attention to the quality when selecting high-pressure hose, so as to avoid unnecessary safety accidents. Oil resistant hose Price The development of rubber hose can not be separated from cooperation, R&D and innovation can not be separated from communication, and the inspection requirements of rubber hose have been improved compared with the previous ones. The storage site shall be free of ozone, heat source and equipment generating electromagnetic field. The coiled hoses or hose assemblies shall be stored horizontally, and the stacking height shall be limited to the extent that the products at the bottom will not produce permanent deformation.

Xiamen Oil resistant hose Prevention of vibration and noise during installation: the prevention of vibration and noise during installation is a key point in the installation process. The prevention of vibration and noise of spiral air duct during installation is mainly from the following aspects: 1. The fan and spiral air duct are connected by hose, and the hose at the suction inlet of the fan shall be installed with appropriate tightness, Avoid noise and vibration caused by reducing the area of air inlet and outlet due to loose soft connection. 2. The spiral air duct shall be made, installed and connected with the components. The connection shall be tight to reduce the gap and avoid air leakage noise. 3 In order to prevent the spiral air duct from vibration, fixed supports shall be installed at the turning of each system spiral air duct and at the connection with the ventilator and the air outlet for shock absorption. 4 The vibration damping device shall be set according to the design requirements or construction specifications during fan installation. Air leakage rate test of spiral air duct After the installation of spiral air duct, air leakage rate test is required. According to the specifications, the air leakage rate test of spiral air duct adopts the combination of light leakage legality and quantitative air leakage rate test. The light leakage method is suitable for the tightness test of medium and low pressure systems; The air leakage rate test is suitable for sampling inspection of medium pressure system and full detection of high pressure system. Light leak detection of spiral air duct Light leak detection is a qualitative method to detect the tightness of the spiral air duct of the system by using the strong penetration of light to holes. The test method is to use a bulb with protective cover whose voltage is not higher than 36V and power is more than 100W in the spiral air duct on a certain length of spiral air duct in dark environment, and slowly move from one end of the spiral air duct to the other end. If light can be observed outside the spiral air duct during the test, it indicates that there is a leak point in the spiral air duct, and repair the leak point of the spiral air duct. Oil resistant hose Price The light leak detection method of the low-pressure system adopts the method of subsection detection and summary analysis. The spiral air duct of the tested system is not allowed to have multiple obvious light leaks in the form of slits. The spiral air duct of the low-pressure system has no more than two light leak points every 10 meters, and the average joint of 100 meters is no more than 16; For every 10 joints of spiral air duct of medium pressure system, no more than 1 light leak point, and no more than 8 joints per 100 meters are qualified.

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 Xiamen Oil resistant 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, Oil resistant 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.
