Fire exhaust fan operation method with process problems

Release Time：2021-07-20

Fire hydrant pump is a tower-free water supply equipment with artificial teeth of fire hydrant management system. The high-power fire pump motor generally adopts three-phase star docking, starting with star triangle. Different motor rated power security equipment has been selected. After selecting different types of isolation switches, communication and communication touch devices, thermal relays, etc., one by one, the ring has already fulfilled the fire control regulations.
Fire exhaust fan is the key machine equipment of building fire protection code. The small output power electric fan motor generally uses triangular direct start. The closed type is to open the fire exhaust fan operating cabinet to solve the fire exhaust fan on the surface of the universal key box. When the fire control management server receives the fire accident data signal and publishes the start exhaust fan data signal, the automobile relay starts, the fire exhaust fan starts, the display lamp and the communication touch start, fire smoke exhaust fan actual operation.
The manual type closed type is the universal key rocker of the fire control cabinet and the fire exhaust fan to control the bank counter, pull the manual type situation, dock, manage the posture of the automobile relay, and then the closed type is the posture together.
The fire exhaust fan starts the display lamp, the communication touch device moves the fire exhaust fan, and the operation of the fire exhaust fan. In the fire control management system, fire fighting is more critical.
When equipped with a fire-fighting smoke exhaust fan, the defrosting ability of the fire-fighting smoke exhaust fan should be fully considered. If the centrifugal fan does not come to the setting time, defrosting cannot be carried out, which will lead to too thick frost layer, even freezing and cleaning, and shutdown. What are the problems that should be paid attention.
1. If the fire-fighting smoke exhaust fan has the function of kinetic energy adjustment, the actual effect can be guaranteed to be maintained in the application. In addition, the fire-fighting smoke exhaust fan can save some electricity and energy consumption. However, there are three key kinetic energy adjustment methods, namely: DC frequency conversion speed change and rotary vane pump no adjustment belong to no adjustment, no adjustment has environmental protection, energy saving, noise and vibration, good start-up characteristics also reduce the impact on the power supply and distribution system.
2. At this stage, the common kinetic energy adjustment methods in air-cooled module generator sets include quantity control of refrigeration compressors, gap operation of refrigeration compressors, and cylinder unloading adjustment (piston machine). DC variable frequency (scroll type) rotary vane pump has no adjustment (air-cooled type). Quantity control can be seen from the kinetic energy adjustment method.
Shandong Xingheng Environmental Technology Group Co., Ltd. is located in Luquantun Development Zone, Dezhou, Shandong, the hometown of FRP in China. The company has Grade II qualification for fire protection facilities engineering, Grade II qualification for construction mechanical and electrical installation engineering, Grade II qualification for environmental protection engineering, and safety production license. It is the first in the industry to pass ISO9001 quality management system certification, ISO14001 environmental management system certification, OHSAS18001 occupational health management system certification, and an axial fan invention patent, A fan utility model patent, environmental assessment, safety assessment, three simultaneous and other procedures are complete.
