Lhasa Sandblasting pipe 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. Sandblasting pipe 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.

Ventilation pipes on ships are generally made of galvanized iron sheet wear-resisting Sandblasting pipe This kind of air duct is generally made by hand, and the production efficiency is low. Later, circular spiral air ducts made by machines greatly improved the production efficiency of air ducts and the quality of air ducts, which were widely used on civilian ships. However, for military ships with very strict height restrictions, circular air ducts obviously occupied more height than rectangular air ducts, which limited the promotion and use of circular spiral air ducts on ships. In the 1980s, 708 Research Institute, the Military Representative Office of Navy Garrison 426 Factory and Dalian Bohai Air Conditioning Auxiliary Factory jointly successfully trial produced the flat spiral air duct. It combines the advantages of the circular spiral air duct and the rectangular air duct. It is the third generation of air duct for ships, which is welcomed by the ship design department and has achieved good results after many ship use. The structure of the spiral air duct is the same as the round spiral air duct. It is also formed by rolling galvanized iron sheet on a special pipe coiler. Therefore, it can be produced mechanically, and the inner surface of the air duct is flat and smooth. The utilization rate of materials is also high. The thickness of galvanized iron sheet is generally 0.6mm. Although it is 0.75~slightly thinner than the commonly used rectangular air duct iron sheet, its rigidity is higher than that of rectangular air duct due to the reinforcement effect of spiral undercut. There are two types of flat spiral air duct: non adiabatic and pre adiabatic. Non adiabatic type is applicable to air conditioning ducts with simple mechanical ventilation, natural ventilation and external insulation. Lhasa Sandblasting pipe There are two types, one is air layer insulation, that is, there is 12.5~thick air layer between the inner pipe and the outer pipe. The other is that the inner and outer pipes are filled with thermal insulation materials rock wool or ultra-fine glass wool to become good thermal insulation air conditioning ducts.

Many people have never understood wear-resisting Sandblasting pipe It is better to use cast iron or rubber lining plate, so today I will give you a detailed analysis. The lining plate of the ball mill can tell you for sure that it is better to use rubber lining plate, which is also a trend for rubber lining plate to replace manganese steel lining plate. The rubber lining plate has many advantages that can not be achieved by manganese steel lining plates such as cast iron, so it has more advantages. One of the advantages of using cast iron or rubber liner for ball mill liner is that the noise of rubber liner is lower. In the process of grinding the rubber lining plate with materials, the noise is lower because it is not directly rubbed. Moreover, the rubber lining plate can throw the steel ball up for the second time to form the second grinding of materials, which makes the grinding of materials more thorough and the grinding fineness more uniform with good effect. In addition, the rubber lining plate can reduce the noise by an average of 30 dB compared with the noise of the cast iron lining plate, making it acceptable. Another important reason is energy saving. Energy consumption is an unavoidable problem for users of ball mills, because the cast iron lining plate is heavy in quality, Sandblasting pipe Price Therefore, when the motor drives the lining plate, it will consume a lot of power. The rubber used by the rubber lining plate itself is light, so the electric energy consumed by the motor when driving is very small, which can be more than 10000 yuan of electric energy a year.
