Single -speed fire smoke is usually the main smoke -proof facilities of high -rise civil buildings, and high -rise civil buildings ensure the safety of peoples lives and property*. However, due to the lack of understanding of the structure, role, and performance of some design and construction personnel, they have a lack of understanding of the structure, role, and performance of smoke -proof facilities.The incomplete understanding of the standards and standards often causes some problems during use. Let me introduce several aspects in detail.
The grounding of a single -speed fire smoke shell or a motor shell must be reliable. It is forbidden to rotate in the opposite direction. It is forbidden to operate by over -the -fixed current.The ventilator.
Preparatory work before installation of a single -speed fire fire exhaust fan:
1. Check whether the packaging should be complete before opening the box, whether the nameplate parameter of the fan meets the requirements, and whether the attachment is complete and complete.
2. Carefully check whether the fan is deformed or damaged during transportation, whether the strong parts are loose or fall off, whether the impeller has the phenomenon, and check the parts of the fan.If an abnormal phenomenon is found, it should be repaired before using it.
3. Use a 500V meter meter to measure the insulation resistance between the fan shell and the motor winding group. The value should be greater than 0.5 mega Euros, otherwise the motor winding group should be dried. The temperature does not allow more than 120 ° during drying.
4. Prepare various materials, tools and venues required for fire fans.
Single -speed fire smoke exhaust aircraft composition mainly includes leaf wheels, air cylinders, imported sets, guides, motors and other components.The impeller is welded on the hub with distorted leaves with the characteristics of noon acceleration. It has a dynamic balance test and an overspeed test. It has good air performance.
