Shenyang ventilation pipeline With the continuous growth of service time, a lot of impurities will accumulate inside. These impurities will be stored in the pipeline for a long time, which will speed up its oil condensation during operation. The temperature transition is too high, which will cause damage to pneumatic valves, hydraulic and other components, and have a great impact on normal operation. So regularly Ventilation duct It is very necessary to clean the equipment. Today's editor introduces several cleaning methods:
(1) When the air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet, and the section dimension of the soft joint shall be the same as the air inlet and outlet of the fan. The hose connector can generally be made of canvas, artificial leather and other materials. The length of the hose should not be less than 200. The tightness should be appropriate. The flexible hose can buffer the vibration of the fan.
(2) Before the connection between the air duct and the dust removal equipment, heating equipment, etc., the prefabrication and installation shall be stopped according to the theoretical mapping drawings after the end of the equipment installation.
(3) When installing ventilation ducts in Jinan, holes should be opened during the prefabrication of air ducts on the day of air inlet and outlet. If it is necessary to open the air outlet on the air duct at the end of the unit, the interface should be tight.
(4) When transporting gas with condensed water or high moisture content, its horizontal pipeline should be set with slope and connected with drain pipe at the low point. When installing, the bottom of the air duct should not show longitudinal joints, and the sealing treatment should be stopped at the joints at the bottom.
(5) For steel plate air ducts transporting flammable and explosive gases, jumper wires shall be installed at the connecting flanges of the air ducts and connected with the electrostatic grounding grid.
(6) When the height of horizontal air duct is more than 4m. The springboard on the scaffold or mobile support shall be fixed, and the width of the springboard shall conform to the * * specification. The installation personnel on the scaffold should carry bags to prevent objects or electric drills from falling and injuring people.
(7) After the double suspender support is in place in the air duct, ensure that the cross arm is straight, the suspender is not changed, and the force on the double suspender is uniform.
