Explain leafy exhaust port functions and technical parameters leafy air vents often installed in the front room stairs, vertical wall design pressure delivery outlet, I produced a variety of types of multi-leaf smoke vents, explain below electric multi-leaf smoke vents about relative performance and features: its main technical parameters: runtime operating voltage / current: DC24V / 0.5A. Amount of air leakage is 290m3 / m2 · h≤700 (pressure 1000Pa time). Temperature sensor operating temperature of 280 ℃. It is composed of body, valves, bushings, thin actuators, grille panel components. Usually do not use normally closed, manual open, manual reset closed. Usually also should pay attention to maintenance to increase service life. Functional and technical specifications leafy exhaust port is mainly these, I believe we already know, and we must be based on the above instructions to select the right product, so its performance is fully displayed, is to continuously improve our work efficiency. Positive pressure blower is pointing escape corridor air blower. It outdoor air pressure into the interior. In case of fire, it will produce a lot of smoke, carbon monoxide and other toxic gases and block line of sight, through positive pressure blower air to escape the fire stairs, indoor smoke can not reach the stairs, to create the conditions for everyone to escape. Positive pressure blower is usually installed in the top of the building, each positive pressure air valve linkage. Open early fire air valve, positive pressure blower starts, stairs, elevator lobby at positive pressure (air conditioning). Note 1. The positive pressure blower installed horizontal position to maintain a positive pressure fan outlet, and connect the fan and the ground and the air outlet pipe should be a natural adjustment, can not be forced to connect positive picture outlet pipe weight should not be added in the wind turbine components . And conduct a comprehensive inspection of the components before installing the fan chamber 2. pressure delivery outlet, filling oil, after checking the fan terminals fastening work is completed, the components tightly connected. 3. The positive pressure blower is running if there is a huge impact on abnormal vibration must be immediately stopped and checked. 4. Check the fan and soft connection between the duct and found damaged replace immediately. Fans use measures should be rain in the open air. 5. Check the stipulated time fan blades, remove surface dirt, remove the internal fan fouling, dirt and other impurities, and to prevent corrosion. 6. positive pressure blower manually move the fan disk checking tightness, abnormal immediately overhaul. 7. Elimination of the control box and the internal surface dust, check the box is the front face of pressure delivery outlet, pressure delivery outlet, Sheng purification of air conditioning provided by the Texas Air Conditioning Equipment Co., Ltd. Sheng purification. Texas Air Conditioning Equipment Co., Ltd. Sheng-purification (www.dzhffj.com) strong, credible, in Dezhou fan, ventilation equipment industry has accumulated a large number of loyal customers.
