u003cpu003e With the development, ventilation duct
s are widely used in various industries, but as the use time continues to increase, a large amount of impurities will accumulate in the ventilation ducts. These impurities will be stored in the pipeline for a long time and will accelerate the condensation of the oil during operation. If the temperature conversion is too high, the air valve, hydraulic pressure and other components will be damaged, seriously affecting normal operation. Therefore, it is very necessary to clean the ventilation duct equipment regularly. But how should it be cleaned up? Today will tell you how to clean it up. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e (1) When the air pipe is connected to the fan, the air inlet and outlet should be equipped with soft joints. The cross-sectional size of the soft joint should be the same as the cross-sectional size of the fan inlet and outlet. The hose connector can be made of canvas, artificial leather and other materials. The length of the hose should not be less than 200, and the tightness should be appropriate. The hose can buffer the vibration of the fan. u003c/pu003eu003cpu003e (2) When the air duct is connected to the dust removal equipment and heating equipment, after the equipment is installed, the prefabrication installation is suspended according to the theoretical measurement and drawing. u003c/pu003eu003cpu003e (3) When installing the ventilation duct, the inlet and outlet should be opened when the duct is prefabricated. If the duct needs to be opened at the end of installation, its interface should be tight. u003c/pu003eu003cpu003e (4) When transporting condensate or gas with a large water content, the horizontal pipeline should have a slope and be connected to the drain pipe at the low point. During installation, there should be no longitudinal joints at the bottom of the duct, and the sealing treatment should be suspended at the bottom joints. u003c/pu003eu003cpu003e (5) For steel plate ducts conveying flammable and explosive gases, jumpers should be installed at the connecting flanges of the ducts and connected to the electrostatic grounding grid. u003c/pu003eu003cpu003e (6) When the height of the horizontal air duct exceeds 4m, the installer should wear a safety belt. The springboard on the scaffold or mobile support should be fixed, and the width of the springboard should comply with safety regulations. Equipment personnel on the scaffold should carry bags to prevent falling objects or injury to people with electric drills. u003c/pu003eu003cpu003e (7) The double boom bracket is in the air duct. After in place, the cross arm should be straight, the boom should not be changed, and the double boom should be evenly stressed. u003c/pu003eu003cpu003eu003c/pu003eu003cpu003e The above is to introduce you to the method of cleaning up the impurities in the ventilation ducts. The ventilation ducts should be cleaned every three months, so as to ensure normal normal operation and extend The service life of the ventilation duct. u003c/pu003eu003cpu003eu003c/pu003e u003cpu003e
