Features
- casing
- (1) The helical construction uses the stator helical method that the screen lines of casing at the suction and discharge sides are cut to a helical shape, and the striangle suction and discharge port formed by a straight line of the rotor top is to be opened and closed and closed gradually. Therefore, the suction and discharge ports of this type is not opened or closed at moments, which makes these blowers have an only limited operation sound and almost free from pulsations from discharge.
- three lobe
- (2) The rotors are three-lobe straight type, so that the rotors can’t interfere with each other, resulting from minor displacements in the thrust direction as in the helical type. Therefore, the clearance between the rotors should be assured in the profile direction only and thus there is no necessity of an excessive clearance on account of displacements in the thrust direction as in case of the rotor helical type. From such reasons, these blowers have a very high efficiency even higher.
- shape
- (3) The rotors are made in a special shape in order to keep the distance between the rotors and raise the efficiency.
- precision of rotor
- (4) The precision of rotors is fully controlled and variation of precision between blowers is almost nil error because the rotors are produced under the mass production control by utilizing the numerical control machine tool. In addition , the rotors are dynamically balanced in the fabrication stage already, so that these rotors are almost free from vibration as in the case of conventional rotors which are still unbalanced.
- driving gears
- (5) The advanced driving gears are adopted not only to extend the use life but also to make noise lower. Therefore, the harmful disturbances to products from gears are avoided.
