Low noise clover Roots blower, Shouguang clover Roots blower, detailing Chang Sheng Machinery: Roots blower selection factors need to be considered in the selection of work blower must first determine the selection centrifugal fan or axial fan, then Select the fan model based on flow, pressure head, blades and motors and other factors, while also meet the blower is installed, the noise size and other requirements. First, to determine the process according to the requirements of the wind is constant flow or constant pressure air supply for wind turbine technology on these parameters exactly to what extent the requirements, once the parameters are affected and what the consequences will bring. Roots blowers are constant flow fans, air flow is the main parameters of its work equipment blowers, piping and load changes affect Roots device output pressure, air volume change is relatively small. The constant pressure centrifugal fans are fans, air pressure changes its main operating parameters of equipment, piping and equipment output load impact sewage aeration blower amount of wind, air pressure change is relatively small. When the main parameters of these devices can cause serious damage to the impact of equipment operation, need to take an additional regulator valve, auxiliary measures bleeder valve, alarm devices and automatic stop device, such as to improve and avoid. It is well known in the field of sewage treatment industry, the blower has been playing a very important role, so the field for the selection of paint fan equipment needs attention, under normal circumstances, a large selection of sewage treatment capacity centrifugal fan, sewage treatment capacity compared Small selection Roots blower. Typically more than 18,000 tons of sewage treatment requires a large amount of stand-alone wind achieve a higher efficiency, and therefore the best choice for centrifugal fans, but the investment cost is relatively high. The 15,000 tons of sewage treatment following wind can choose a smaller stand-alone equipment, small investment, has a good economy. More than a few factors at work in the selection of Roots blower is the need to fully consider the underlying porous pipe pond aeration equipment anti-acid, high temperature, non-hardening, the pond will not use basic bad. Roots blower accessories can be chosen according to the different pore water quality pond aeration head, to avoid clogging the aeration head, reducing the number of cleanings aeration head. Microporous diffuser performance parameters; diameter: 13mm inner diameter: 9mm bubble diameter: 0.15-2.5mm oxygen utilization: ≥30% air flow: 0.1-0.25m3 / hm suitable depth: 0.5-4m installation (1), will be in charge of in accordance with the requirements of a fixed connection is good, and to determine the interface bit manifold. (2), the fan with the competent connected. (3) will be fixed on the head of the branch pipe connecting piece blower repair and straighten furnished to the surface. (4), the aeration head inserted in the branch pipe and branch pipe sink to the bottom (in the bottom of the manifold requires a flat cross-shaped). Roots blower Features: 1, low noise. Fan intake and exhaust ports spiral shape of the intake and exhaust process in the direction of progressive spiral cut, while avoiding the old exhaust fan exhaust fan ?? instantaneous outbreak pulsating noise and vibration. Fans of the series with a female anti-composite muffler further reduces noise. 2, high adiabatic efficiency and volumetric efficiency, thus saving. The use of advanced composite rotor fan curve, meshing is more reasonable, and increases the volumetric efficiency. 3, stable performance. The key parts of the fan rotor, casing, wall panels, shafts, etc., are the use of advanced digital processing equipment, no need to study the impeller, completely interchangeable assembly. 4, small vibration. Although the rotor through precision machining, has become a state of equilibrium. But still high precision balancing equipment balance. Therefore, almost no vibration fan operation. 5, using high-precision, high hardness synchronized gear, life has been extended not only to fans, but also effectively reduce the noise. 6, this series of fan bearings from Japan or Germany, Korea or Taiwan imported rubber band, so that product quality is more reliable. 7, the output air is clean and free of any oil and dust, fan sealing structure is reasonable, so that oil can not enter the chassis, thus the air clean
