Customer questions and recommend a Roots blower enclosures, blower noise is how much? Roots blower noise is generally about 70 ~ 80dB. 2, the noise blower main causes? Roots blower noise is mainly composed of mechanical noise, aerodynamic noise, electromagnetic noise and other components, aerodynamic noise is mainly intake and exhaust noise, and to exhaust large. Mechanical noise radiated by the cabinet, electromagnetic noise is generated by the electric motor. Roots blower noise is the sound generated by the noise source integrated. 3, how to solve the noise problem blower? The method is usually the fan noise problem solving are the following: 1) the noise and the motor housing can be solved by the installation of acoustic enclosures within the inter-dust transport Roots blower, the blower fan placed in a separate sound insulation between the fan inside were sound absorption, sound insulation. 2) in the estuary exhaust fan installed muffler, built-in silencer inserts, make noise can continue to cut through a special structure. Muffler is to reduce the aerodynamic device intake and exhaust ports or effective measures to deliver radiation noise along the tube. 3) Whenever possible, use outside on the ground floor shutters acoustic louvers. 4) the use of fans hanging absorber damping spring hanger. 5) on the basis of the overall fan vibration isolation. After the installation of energy efficient aeration bottom Roots blower (blower aerators), due to the water environment has been improved enough oxygen in the water, aquatic breeding strong vitality, feeding strong, fast growth, individual large, uniform specifications and shorten the breeding cycle , thereby reducing the risk of farming farming costs. So, in addition to increase in production, the sale price may be raised, the overall efficiency has also been improved significantly. Dissolved oxygen in water according to the laws change clover Roots blower, Roots blower aeration determine boot time and time period. Generally April-May, rainy day turned midnight; June-October afternoon boot for 2-3 hours before sunrise boot for 2-3 hours or low contact rainy weather, night 21: 00-22: 00 boot, until noon the next day; late intensive farming roots blower, ground boot, promote the growth of aquaculture object. Dissolved oxygen conditions were detected, timely boot, to ensure that the water of dissolved oxygen in the 6-8 mg / upgraded to good.
