According to the appearance, the steel structure roof downhill ventilator can be divided into two types: thin roof ventilator and streamline ventilator. The former has a rectangular appearance, low height, and good ventilation and smoke exhaust performance; the latter has a streamlined shape, beautiful appearance, uniform ventilation and lighting. Throat downhill ventilator is widely used in workshops and workshops in warehousing and logistics, metal metallurgy, home building materials, electronic components, automobile manufacturing and other industries, so how to maintain ridge ventilator in the later use process? Next, Mcwell will introduce some maintenance tips to you.

The steel structure of ridge ventilator installed on the slope of the factory building has good ventilation, smoke exhaust and lighting performance, but if it is improperly maintained in the later use process, its functional use will be affected, so it is necessary to understand the maintenance methods and measures.

1. Regularly maintain the throat-slope ventilator, and clean up the dirt, dust and other impurities accumulated inside the ventilator.

2. Every month of operation, use butter to inject calcium-sodium-based grease or molybdenum disulfide grease into the bearing of the down-slope daylighting ventilator to ensure that the bearing runs smoothly and smoothly. The smoke vents needs to be replaced with grease every three to five months, and the amount should be two-thirds of the bearing space.

3. For the sloped roof lighting ventilator that has not been used for a long time, the rotor should be rotated 120°-180° regularly to avoid the phenomenon of main shaft bending. It is closed, and the valve is opened after operation until the specified working conditions and the joint tightness of the inner ring and the shaft are met.
