Ventilators and precautions in use during installation as follows: ventilators Caution: Tel; 18663505583 15506519090 0635-2790980 1. ventilators use will produce high temperature, you should avoid touching the housing to avoid burns. 2. The motor load current with the drum using air pressure ventilators of change. Wiring should apply to aircraft types of device overload protection switch, and use the full load current (A) below, in order to prevent motor burnout. (Please refer to the nameplate rated full load current on the motor) Scope 3. Ventilation is shut continuous operation, refer to the directory on the air volume - static pressure curve, and used within the scope of the curve, but as close to the high pressure, do not exceed the applicable range, must close if the use of a closed pressure, it is best to set the pressure relief valve in the pipeline, when the line closed, the pressure relief valve will open and out of the conditioned air ventilation to ensure the life of the drum. If the running in the pipeline closed down, the ventilation temperature will soar, and you should avoid continuous operation, or it may be deformed or damaged, while in the closed condition. If intermittent operation, preferably air valve switching manner. The ventilation air temperature change: When the air flow close to the closed state, the temperature will soar, it should pay particular attention to this situation occur. If the temperature rises, do not use the ventilator in an enclosed interior. 5. hard object fiber dust particulates and water droplets should be removed before the air enters the ventilation, dust collection bags available manner. If the halfway line filter device, in order to avoid the loss of blood pressure, use a large area of ??the filter, and regular cleaning of the filter should be periodically cleaned of contaminants 6. ventilators internal and external (especially the cooling fan air passage ) to remove surface dirt. If an accumulation of dust can cause poor cooling effect temperature rise, reducing the amount of wind, vibration caused by faults increase. 7. bearing oil seal and muffler are consumables, so there is a certain life span, to be regularly replaced, while the blade housing metal also must be replaced periodically depending on use environment. 8. If you use ventilators or unusual noise, uneven operation occurs, turn off the power maintenance. Ventilation Installation Notes: www.lchttfsb.com www.lcrxfj.com www.ruixingtfq.com. 1. Install location ------- shall be installed in the indoor place from the wind and rain intrusion; 2. Ambient temperature ------- 40 ℃ about; 3. Relative humidity ------- 80% about; 4. Air quality ------- air if they contain acid, alkali and other corrosive or flammable gases, should not use high-pressure drum ventilators delivery, to avoid danger; 5. Dust Protection --- ---- there is a lot of dust, powder, or three-dimensional fiber and other places should be avoided, as must be used in such a case, please install the filter, and regular cleaning of filters and dust attached to the interior of the high-pressure drum ventilation; 6 . ventilation ------- select Use in a well-ventilated place, can not be used in a closed room or in a closed box; 7. ------- placement space for the column or row convenient maintenance repair, please Avoid installing the place is too small; 8. Avoid vibration -------- Install the free vibration places; places such as vibration is inevitable, anti-vibration measures should be installed to avoid high-pressure drum ventilators subjected to vibration outside the damage.
