Advantages of three cattle NSR series Roots blower and blower constructed three cows a year replacement, low noise blower. Fan inlet and exhaust ports using spiral structure, so that the rotation of the intake and exhaust fan with the rotor gradually be three cattle MJ Roots-type blower, avoiding the old fan pulsation and noise due to the opening and closing moment generated, and therefore the operation smooth, low noise. Products supporting the silencer uses an advanced sound-absorbing materials and special structures, but also effectively reduces the fan noise. 2, blower smooth, vibration-free. The adoption of advanced machining center dedicated impeller machining the rotor backlash uniform, and the formation of an equilibrium state, on this basis, through more sophisticated rotor balancing test, the fan running almost no vibration. 3, high blower efficiency and low energy consumption. Using a specially designed fan rotor meshing curve for advanced composite line, sealed, leak less, volumetric efficiency is further improved. 4, Roots blower long life. 20CrMnTi fan gear used carburizing treatment, grinding, precision up to five sewage treatment dedicated blower, the tooth surface more resistant. Bearing with large carrying capacity double roller bearings. Thereby increasing the life of the fan. 5, the blower output air clean. Fan with a special structure designed to avoid the Oil substances into the casing, so the output air without any oil. 6, standardized production Roots blower. Including attachments for all fan products, have achieved a standard design and production, good interchangeability and versatility to meet the high-quality, low-cost, mass production purposes. 7, Roots blower selection easy and reasonable. Product specification and more tranches finer performance parameters intensive. Therefore, to facilitate customer choice blower, reducing the cost. 8, the series Roots blower bearings imported from Japan NSK Bearings. There are two kinds of lubrication, 0.6kgf / cm2 or less lubricated with grease, 0.7-0.9kgf / cm2 using splash oil lubrication, product quality and more reliable. 9 \ belt drive blower clover US imports GATES belt. Depends on what technology, if it is the case of CASS SBR or changing the water level increases with frequency Roots blower is the most energy-efficient, and if it is A / O process, then use the water level constant high centrifugal fan efficiency, because by the inverter also centrifuge only tune traffic, can not adjust the pressure blower flow and pressure through the frequency can be adjusted. So look at the process, of course, it also depends on the funds dedicated biogas Roots blower, centrifugal blower Bi Luoci expensive. Roots fan flow of 40m3 / min or so fans are small fan, blower should be sufficient, centrifuge at 100m3 / min or more to show the advantages of energy on it, in a small flow regardless of price or energy are Roots blower dedicated biogas is more practical, three cattle machinery (certified), Binzhou Shandong Roots blower is provided by three cattle Machinery Limited. Machinery Co., Ltd. Shandong three cattle (www.sanniujixie.com) Shandong Jinan, the other leaders over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In three cattle mechanical leadership with the staff warmly welcome all inquiries negotiations to create three mechanical cow a better future.
