The consumption of galvanized iron sheet air duct in China's chemical industry also shows a rapid growth trend. The rapid increase in the consumption of galvanized iron sheet air duct in China's chemical industry has stimulated domestic Sandblasting pipe Where can I find it? With the rapid development of industry and the support of relevant government policies, in a short period of time, the production of galvanized iron air ducts in China has been developing rapidly. From the perspective of industrial chain, galvanized iron duct and upstream and downstream products enterprises of galvanized iron duct are interdependent and competing industries. Steel production enterprises can establish long-term and stable strategic alliances with downstream enterprises through deep processing of steel products, which is conducive to promoting the development of new varieties, quality improvement and market expansion of galvanized iron sheet air duct industry, and is an effective way to extend the value of steel products to the downstream and improve the competitiveness of the product market. It can be said that the development of high-quality galvanized iron duct projects has become a development strategy for Chinese galvanized iron duct manufacturers to cope with fierce market competition and improve product competitiveness. At present, in the consumption structure of galvanized iron duct in China, except for some high-end products that still rely on imports, middle and low-end products can basically achieve self-sufficiency. The situation that galvanized iron duct consumption completely depends on imports has been greatly improved, and the export volume is also expanding rapidly. However, compared with the developed areas of galvanized iron duct industry, China's galvanized iron duct industry system is not perfect, and there is still a big gap compared with Japan, South Korea and other large stainless steel reactor production countries. The development of galvanized iron sheet air duct industry in China started late, and the social demand for stainless steel reaction kettle grew too fast, which led to high quality Sandblasting pipe The first problem to be solved for industrial development is to rapidly increase output to meet the growing social demand, gradually replace imports, and complete the two steps of "quantitative change" and "qualitative change". At present, the development of galvanized iron duct industry in China has completed the accumulation process of "quantitative change", and is currently facing the transformation of "quality".
We all know Sandblasting pipe Where can I find it? 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). Yantai Sandblasting pipe 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.
high quality Sandblasting pipe 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 pipe 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.
How to install correctly Yantai Sandblasting pipe ？ 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 pipe 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.
