To undertake ventilation cooling engineering approach:
1, according to the characteristics of ventilation engineering, facilities should be wide, bright and clean, flat on the ground. The basic equipment and power supply equipment and equipment to be thoroughly processed.
2, ventilation pipe equipment to equipment parts of the obstacles have been arranged, the ground without obstacles to the construction of the conditions of the debris.
3, the equipment in the building layout has been done, indoor rough decoration and interior walls, floors have been done under the conditions of the equipment, and now the ventilation system of dry pipe is also good equipment.
To undertake ventilation cooling engineering needs:
(a) ventilation duct manufacturing methods and requirements:
1, ventilation and smoke exhaust engineering application of the first materials, equipment, products, such as semi-finished products should have a certificate or quality determination.
2, ventilation works must be agreed in accordance with the planning drawings.
3, ventilation pipe manufacturing scale should be in accordance with the map construction, are in the diameter of the standard, the connection should be consistent with the valve body.
4, the radius of the circular bend and the minimum number of nodes and the tortuous radius of the rectangular pipe should be the "construction equipment engineering construction skills operating procedures" in accordance with the relevant provisions of the.
5, circular air duct of the three links, the angle of 90o.
6, the connection of each pipe section of the wind pipe should choose the detachable way.
7, the thickness of the wind pipe according to the standard.
(two) equipment preparation:
1, parts and equipment should be carried out as follows, through the examination of qualified and fill in the relevant inspection materials can be carried out after the equipment:
1) air appearance should be flat, error <=2mm, rectangular outlet diagonal difference <=3mm, arbitrary orthogonal two diameter circular nozzle promise error <=2mm.
2) the change of some air should be sensitive, leaves or plate should be straight, leaf spacing should be uniform, diffuser expanding number of rings and conditioning should be coaxial, the axial distance distribution symmetry, blade opening and closing thoroughly, air sealed valve direction and shock wave is accurate, not anti loaded, open or full leaf fully closed, no air conditioning for use.
3 various types of valve manufacturing should be strong, conditioning brake equipment should be accurate and sensitive, reliable, and indicate the valve opening and closing direction, fire valve shell thickness should be greater than or equal to 2mm, material selection should meet the GB50243-97 standard requirements.
4) air filter system with flexible tube type rubber, other selected three fire canvas, the crane, supporter, weld should be flat firm, plump, arc hoop should be uniform.
