Safety and waterproof performance of ventilation skylight

The safety and waterproof functions of ventilation skylights are also important targets. No matter what kind of roof ventilation ventilation technology is chosen, if the rain and snow fall into the unqualified 12 type ventilation skylight, ventilation skylights should not take extreme climate as the cause of the problem. The whole structure waterproof technology is adopted, and the traditional glue waterproof technology is abandoned, which completely avoids the leakage of ventilator caused by the aging crack of silica gel and eliminates the risk of water leakage.

 
 
Briefly speaking, ventilation skylights are actually equipment for transporting gas. It is also a kind of conversion of mechanical energy of prime mover to gas transportation and gas energy machinery. It is not a mechanical equipment in cement plant. First of all, there are air conveyance buildings, air induction towers, a gas tower, sealed gas towers and exhaust buildings. Ventilation windows are in practice, especially in the condition that the air conveyance buildings are in bad condition, and there is a higher rate of unpowered wind caps. The reason is that the adoption of force method is the guarantee for the continuous operation of the factory.
 
Bearing overrun in ventilation skylight bearing oscillation is a common problem in operation. Air tower oscillation causes damage to bearing and blade, loosening bolts, damage to casing and air duct, and seriously endangers the safe operation of air towers. There are many reasons for excessive vibration of air bearing bearings. If we can adopt appropriate methods for different reasons, we can get twice the result with half the effort. Ventilating skylight treatment blades, non working area, ash falling, air tower oscillation: this kind of defect is common in the mill air guiding building, and the main phenomenon is the sudden rise of oscillation in the operation of the air tower.
 
This is when the gas enters the impeller, there must be a point of view with the working surface of the rotating blade. The principle of fluid mechanics is that there must be a vortex in the non working surface of the gas blade, and the effect of the dust particles in the gas will gradually accumulate on the non operational surface. Wing blades tend to accumulate dust. When the ash reaches a certain component, the centrifugal force of impeller rotates a large part of ash into the impeller. The accumulation of ash on each blade can not be completely uniform. The time of assembling or throwing away the ash block is not necessarily synchronous. The uneven deposition of the blades results in uneven distribution of the impeller mass and the oscillation of the air tower.
