Sunrise environmental equipment DWT-IV series without power fan factory outlets, workshops, farms ventilation

Non-powered fan is to promote the use of natural natural wind speed rotation of the turbine fan, and the indoor and outdoor air convection principle, parallel to the air flow in any direction, and into a bottom vertical acceleration of the air flow, in order to improve indoor ventilation change An apparatus for gas effect. The fan no electricity, no noise, long-term operation. Based on air flow and air flow principles of natural law, is set at the top of the roof of rationalization can quickly exhaust gas indoor hot and dirty, improve the indoor environment. Contents 1 works two special energy efficiency cost 3 4 5 Maintenance application note uses an editor works is the use of natural wind turbine fan and indoor and outdoor temperature difference caused by air convection, drive a turbine [1] in order to make use of centrifugal force and negative rotation effects of indoor stale hot air out. 2 edited a special energy efficiency, curved blades is the result of the best results of scientific computing, to strictly ensure the working state without power fans never let rainwater intrusion. High exhaust efficiency, as long as not less than 0.2 meters in the breeze or indoor and outdoor temperature difference exceeds 0.5 ℃, can be lightweight, efficient operation. 2, the central axis has a fine level, so that the high-speed operation of the turbine blades never deformation, which greatly improves the fan's life. 3, variable angle neck design allows the fan at 0-22.5 degrees bevel under arbitrary installation, the installation is very simple, it is generally within about thirty minutes to complete the installation. 3 using edit costs zero cost operating costs, energy efficiency objective, economic installation costs, low maintenance cost. Without power fan applications (2) 4 editing application uses no power fan purposes: one, to produce air convection cooling exhaust gas. 2, to reduce the air conditioning load, increase the indoor fresh air. 3, the moisture out of the roof, Mei Qi, steam, keep the roof dry. 4, instead of heavy-duty electric blower, reduce electricity cost savings bracket, subtract noise. 5 Maintenance edit a note, no power fan Under normal circumstances, about a month of continuous operation, the bearings should be injected into the sodium or calcium based grease molybdenum disulfide grease with butter site. Fan runs continuously for 3-6 months to replace a grease to the bearing space is filled 2/3 appropriate. 2, no power fan periodic maintenance, eliminating the fan inside the fouling, dirt, etc. 3, in the non-powered fan boot, shutdown or operation, such as found in unusual circumstances, including temperature, vibration, noise, etc., should be inspected immediately. 4, an adjustment device will keep the uniform triangle tape taut, not too loose or too tight. Several triangle tape should be the same length. 5, for the unused spare machine or disable long time fan, you should regularly rotate the rotor 120 ° -180 °, in order to avoid bending the spindle. Fans on the roof without power imports or exports plus valve, turn it off at the start, will open the valve operation, to achieve the required degree of working conditions, the inner ring and the shaft with tightness. 6, to ensure personal safety, the roof without power turbine maintenance must be carried out at the time of shutdown.
