Features and Benefits rotary blowers and other similar fan: ● Small size, air volume, low noise, energy province (rotary blowers uses the principle of operation of compressed air, though small in size, but large amount of wind, energy efficiency, quiet operation is the other in the form of fan incomparable ● smooth operation, easy installation (as long as it is properly seated minicomputer species is minimal vibration during operation, does not require the installation of anti-vibration device, easy to install) ● Anti-load changes, wind stable (eg: sewage treatment aeration tank pressure changes, the load changes, but the amount of wind pressure changes with little change). ● with the air chamber, bulk gas stable (all models with air chamber to prevent air pulsation, smooth bulk gas). ● material well, clever structure, performance (blowers all use high-quality materials, compact structure, durable, high performance, long-term use less failure). ● Maintenance is simple, less failure, long life (low-speed, low wear and long life ) rotary blowers during installation and commissioning Notes: (a) the installation of a rotary blowers, please pay special attention to safety when transporting rotary blowers, rotary blowers should be avoided by the bumps and shock, and not be able to rotary blowers handling erected to prevent oil poured out from the tank. 2, room air vents should be left to install ventilation fans, vents to be set up in two easy air flow up and down, in order to prevent the room temperature is too high impact rotary blowers and running. 3, around the inner wall of the room is equipped with the best sound deadening material to reduce noise. 4, rotary blowers should be installed horizontally. 5, with a diameter of not less than gas exhaust diameter rotary blowers, and pay attention to the pipe cleaner, feed pipe should be installed above the water, in order to prevent the water inside the tube causing excessive pressure when starting. 6, be careful not to take over when the valve is screwed down (check the raised portion should be facing up). 7. Correctly connect with Wire and attention turned to the rotary blower motor rotation direction markings on the 8, using two rotary blowers alternate operation, avoid frequent switching in a short time starting fan, want continuous running time of a rotary blowers are not low for 12 hours. (b), commissioning a, oil tank inspection rotary blowers whether standard (oil should be above the hole location). 2, before starting rotary blowers please win air intake filter clear is, to pour about 30ml of oil within the host, so that the oil evenly distributed in the interior rotary blowers (hand turn laps). 3. Check the V-belt tightness is appropriate, such as too loose, adjust 4, checks safety valve is set at the specified pressure position, such as work pressure is 0.3kgf / c㎡; safety valve opening pressure of 0.3kgf / c㎡ in test run, you can manually adjust the exhaust valve opening pressure boost to adjust. just open the valve so that it (the pressure is 1.1 times the working pressure) 5, power starting fan, please note the following: The steering is consistent with the shift marks indicate the direction a, rotary blowers, such as inconsistencies immediately stop adjustment motor wiring. b, (to run rotary blowers sewage treatment tank must be filled with water, otherwise rotary blower vent without pressure, the rotary blowers no lubrication) to observe whether the pressure indicator gauges. C, observe the drip nozzle inorganic droplets (10-12 drops / min), and observe whether there is a transparent oil flow return pipe. 6. Check the motor and rotary blowers ministries functioning properly, the temperature is normal, if there is abnormal sound. Rotary blowers at the factory should include the following: Each set includes fans, motors, air filter, air chamber, drip nozzle, safety valve, check valve, outlet pressure gauge, and fuel tank chassis, shock absorbers, gear, ground connection bolts and anchor bolt a lubricant between the various components.
