Foundation construction clover Roots blower commonly used secondary grouting method, so you can ensure proper fan base and bolt hole butt secondary grouting method in foundation watering clover Roots blower basis, the use of mold left on the basis of inside bolt mounting holes, and then put on the amount of wind anchor bolts when installing the fan blower, then concrete or cement mortar to fill the holes for the following is the basis trefoil Roots blower construction process: 1, actinomycetes power blower, excavation solid foundation; 2, nail Templates, steel, placed bolt holes for pouring mold; 3, pouring concrete; 4, removal of the template. ◆ host shell blower Roots blower housing, base, wall panels, fuel tank, rotor, gray cast iron HT250 manufactured by using resin sand casting, aging treatment. Surface design of the ridge-like projections small blower, not only played at a high temperature is not easy deformation blower, cooling surface and increase the surface area of ??the fan, the blower case design temperature of 160 ℃. Interface machined to smooth, to ensure airtight assembly. ◆ clover Roots blower rotor made of gray cast iron HT250 manufactured rotor leaf type line arc line. Taiwan uses four-axis CNC machining center with movable, once forming, high precision. Rotor balancing rigorous accuracy of G2.5 level, so that the exhaust air flow quite smoothly continuous, and shrink fit secured to the shaft, the rotor during operation without touching the friction between the two, no water seal and lubrication. Rotating blades static balance and dynamic balance in line with VDI 2060 Q-6,3, ISO1940 and ANSI S2.19 G2.5 standards.
