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 anchor bolt mounting holes, duct ventilation blower, then put on the fan when installing the bolt, gas, gas delivery pressure blower, then concrete or cement mortar to fill the holes for the following is clover Roots blower foundation construction process: 1, actinomycetes, excavation solid foundation; 2, nail Templates, steel, placed bolt holes for pouring mold; 3, pouring concrete; 4, removal of the template. Clover Roots blower is a positive displacement blower, through rotation of the impeller, the amount of a certain volume of air from the intake end to the exhaust end of compulsory delivery, ignore the back-flow factors, wind turbine delivered per revolution is constant, and therefore, Shijiazhuang Roots blower fan of the air volume actually suit the machine speed is proportional to the relationship, the greater the speed, the greater the amount of wind. Moreover, size of the wind, almost exclusively a relationship with the speed. You can simply say, Roots blower is to force the air from the intake end to a discharge end of the conveyor displacement machine.
