Ventilation skylights need not be explained too much. In our daily life, we often see that for some factories, ventilation windows are usually installed on roofs to ensure safety. What are the maintenance details of roof natural ventilation skylights? What are the installation methods of ventilation skylights?

Installation method of ventilation skylight

    1. Locate the outlet.

The physical orientation of the ventilation skylight should be close to the ridge line. First, the waterproof substrate is placed on the roof, and the edge of the tilted edge of the substrate is embedded into the roof metal cover, which has a depth of about 10-20cm..

    2. Based on the opening of the base port.

The waterproof base plate has an inner hole, and the inner hole is for reference. The outline of the hole is drawn. Then, the opening of the end hole of the roof cutting machine is then used. Then, the cutting opening is trimmed and polished. After that, the insulation cotton is cut by the rice type, and the part is removed, and then the aluminum foil and the thermal insulation cotton are inserted between the steel plate and the thermal insulation cotton.

    3, device plate node fastener

The general ventilation skylight is made up of adhesive tape or silica gel for plugging and plugging. The natural ventilation unit of the main unit is used for waterproofing treatment. The special structural parts and fasteners are mainly made of metal materials and moulds.

    4, fixed waterproof valve plate

The fixing of waterproof substrate is very important. We should use at least 10 rivets or self tapping screws to fix the waterproof base on the roof and weather resistant glue.

    5. Installation of variable angle neck

After the waterproof base plate is fixed, the variable angle pipe neck is installed on the substrate, rolling the rotatable part, adjusting by the level instrument, making the upper part of the variable neck pipe level.

    6. Fixed angle neck

It is very important to fix the neck of the variable angle pipe. It is necessary to use at least four self tapping screws to fix it on the base plate. Then use metal clip and aluminum rivet to fix the two parts that can be rolled up and down on the neck of the horn tube, and pay attention to aligning the original marking mark together.

    7. Fix the turbine head on the neck of the horn.

The four supporting arms of the turbine head are safely inserted into the reserved trenches, and four screws are used to fix the turbine heads on the neck of the horn.

    8, check and adjust the check screws, rivet reliability.

Then check whether the turbine head is rotating smoothly. Sometimes the turbine head is slightly extruded due to the transportation or installation process. It can be adjusted slightly by hand. Since then, the ventilating skylight device has ended.

Roof natural ventilation skylight maintenance details

    1, ensure the cleanliness of the environment.

The use of the environment should always be neat and tidy, the roof has no power, the exterior of the blower is clean, and there should be no debris in the inlet and outlet.

    2, long time should not be used for temporary line power supply.

It can only work under the normal condition of the roof without power fan. At the same time, it is necessary to ensure that the capacity of the power supply equipment is sufficient, the voltage is stable, and the phase work is forbidden. The power supply line is necessary for the dedicated line, and the temporary line should not be used for a long time.

    3. No abnormal appearance must be stopped.

During the working process, the rooftop unpowered fan was found to have abnormal sound, severe motor fever, shell electrification, switch tripping and inability to start and so on. During the working process, it should be shut down for inspection immediately. In order to ensure safety, it is not allowed to repair in the fan work. After maintenance, it should be tested for five minutes.

    4, do not regularly make up or replace grease for bearings.

According to the conditions of the environment, it is necessary to make up or replace lubricating oil for the bearing (motor closing bearing is not replaced by lubricating oil during the service life). In order to ensure the excellent lubrication of the fan in the working process, the number of refueling is not less than 1000 hours / times, the bearings and motor bearings are closed, and the 2/3. of the ZL-3 lithium grease filled inner and outer rings of the bearing is prohibited from oil filling.

    5, do a good job of rain prevention measures

No power fan on the roof should be stored in a dry environment to avoid motor dampness. When the fan is stored in the open air, there should be rain prevention measures. During the storage and transfer process, fans should be avoided to avoid bumping.

Here is the introduction of the installation method and maintenance details of the roof natural ventilation skylight. I hope this article can bring value to you.
