Abstract: A staggered-teeth diamond saw blade includes a circular steel base and a side wall provided at an outer edge of the steel base. Multiple first diamond cutter heads and multiple second diamond cutter heads are alternately arranged at the side wall through laser brazing; multiple diamond teeth protection cutter heads are uniformly distributed on an external surface of the steel base through high frequency induction brazing; a pre-plating layer is preformed at a welding surface where the side wall is welded with the first diamond cutter heads and the second diamond cutter heads; a pre-plating layer is preformed at a welding surface where the external surface of the steel base is welded with the diamond teeth protection cutter heads. The diamond cutter heads of the present invention are staggered to thicken the thickness thereof while cutting concrete pavement and other materials at high speed.

Abstract: A multi-purpose cooling method and system is disclosed that includes a temperature sensor configured to sense a wet bulb temperature of atmospheric air at a cooling tower. The system also includes a first valve fluidically coupled to a first load center and the cooling tower, and a second valve fluidically coupled to a second load center and a chiller. The system further includes a heat exchanger including a first inlet fluidically coupled to the first valve and a second inlet fluidically coupled to the second valve. The first valve is configured to direct a first fluid and the second valve are configured to direct a second fluid according to the wet bulb temperature, a first target incoming temperature of the first fluid for the first load center, and a second target incoming temperature of the second fluid for the second load center.
