Clover Roots blower

   Works
     Positive displacement blower fan, air volume delivered in proportion with the number of revolutions, clover type impeller rotates once every two impellers by three times the suction and discharge, compared with two leaf type, gas pulsation is reduced, load changes small, high mechanical strength, low noise, vibration small.
     In two parallel shafts no two impellers, and always maintain a slight gap between the impeller and the oval hole in the chassis side and all three of the impeller, the impeller due to uniform rotation in the opposite direction to each other, so that the box and enclosed impeller certain amount of gas from one side to the suction side of conveying discharged.
     Old Roots blower, both two-leaf type, clover type, compression principle is: the rotor tip line open to the air vents of the moment, the exhaust port of the high-pressure air counterflow between the chassis to compress this countercurrent and compression produces intense pressure turbine noise causes of changes in the formation. This machine is to eliminate such factors studied spiral shape.

    Features and construction
  A low noise. Fan intake and exhaust ports with a spiral structure, so that the intake and exhaust fan rotation with the rotor gradually, to avoid the ripple and noise due to the old fans turn on and off instantly generated, and therefore smooth operation, low noise. Products supporting the silencer uses an advanced sound-absorbing materials and special structure, effectively reducing the noise of the fan.
  2, smooth, vibration-free. The adoption of advanced machining center dedicated impeller machining the rotor teeth together uniform gap, and the formation of an equilibrium state, on this basis, through more sophisticated rotor balancing test, the fan rotates almost no vibration.
  3, high efficiency, low energy consumption. I turn the fan using a specially designed, ratcheting curve for advanced composite wire sealed, leak less, volumetric efficiency is further improved.
  4, long service life. 20CrMnTi fan gear used carburizing treatment, grinding, precision reaches five, the tooth surface more resistant. Bearing with large carrying capacity double roller bearings. Thereby increasing the life of the fan.
  5, the output of the air clean. Fan with a special design to avoid the Oil substances into the casing, so the output air without any oil.
  6, standardized production. 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. Selection convenient and reasonable. Product specification and more tranches finer, denser performance parameters. Therefore, to facilitate customer choice and reduce costs.

Roots blower Notes
   1, the power to start the fan, the fan should turn in the same direction with the steering mark indicates.
   2, daily inspection, eliminating filter dust and obstruction.
   3, routine inspections, wind oil level. Oil tank has reached the standard.
   4, such as abnormal vibrations or excessive noise fans immediately stop checking.
   5, the motor should be fair use. Note overload, phase.
   6, check the belt tension degree, such as tensile too large please change the belt.
   7, the host can not rain, must scaffolding protection should stay around or about two vents.
   8, the fan should be installed horizontally, to avoid bumps and shocks.
