How to deal with low temperature environment for spiral duct fan equipment
The spiral duct fan must be affected under the environment of low temperature. How should the spiral duct fan manufacturer deal with this situation? The priority is to keep warm and choose thermal insulation materials, but the selection of thermal insulation materials is also required. The manufacturer of spiral duct fan will tell you how to choose.
The thermal insulation performance is good. Secondly, the specification of thermal insulation materials should meet the requirements of air duct system. Not only that, but also the design requirements of air duct. Thermal insulation materials should have product quality certificates and other certificates.
The air duct is effectively protected by thermal insulation materials so that it will not be damaged in winter. For the clean air duct, the flame-retardant closed cell rubber plastic sponge thermal insulation material is generally selected, and the non combustible aluminum foil glass wool board is used for the smoke exhaust air duct. These two materials are widely used and have good thermal insulation performance.
Before wrapping the spiral air duct with thermal insulation materials, glue shall be applied. The thickness of the glue shall be uniform and there shall be no glue flowing. When laying the thermal insulation materials, it can effectively ensure that the bonding is tight where the bonding is, and there will be no hollowing, and there will be no exposed air duct.
In the installation and construction of underground works, the mature use of complete sets of production equipment such as automatic production line of spiral air duct, plasma cutting machine, circular elbow forming machine and caulking welding machine makes the production of circular air duct change from manual operation to mechanized and automatic operation; The development and application of supporting construction technologies such as connection of inner expansion core pipe without gasket and the introduction and improvement of construction machinery have increased the installation and construction efficiency of spiral air duct several times. These technologies and equipment improve the quality, speed and appearance technology of ventilation engineering construction.
