Roots blower principle blower rotated in opposite directions two impellers, since the gap between the impeller and the impeller, the impeller and the casing, the impeller and the wall between the minimum, so that the air inlet is formed a vacuum state, under the action of air at atmospheric pressure into the intake chamber, then blower outlets, two of each impeller blade and the wall, cabinet constitutes a sealed chamber wholesale blower intake air chamber in the process of rotation of the impeller, are two The continuous strip to form a sealed chamber discharge chamber, and because the exhaust cavity of the impeller are mutually engaged, whereby the air squeezed out between the two blades, so that continuous non-stop operation, air is continuously blades transported from the intake port to the outlet, which is the entire work process Roots blower. Roots blower used in the breeding industry: a rectangular sink or concrete ponds of shrimp nurseries nursery nursery room which is usually made of fiberglass pools, the volume of 10 to 15 cubic meters of water must pass through the nursery 2-4 times filtered. Roots blower price, unicellular algae culture treated water is more stringent. heating boilers available blower or coal boilers, hot water circulating in a way. Roots blower inflated. Second, the selection of healthy seed shrimp cultivation without injury weighing 50 to 60 grams of seed shrimp, with male and female ratio of 1 to 1: 1 into the flume stocking stocking density of 4 ~ 5 / m, water temperature 26 ~ 27 ℃ 33 to 35 parts per thousand salinity, daily keeper. Pool water changes of about 50%, and inflated with black shading keeper pool cover, pool illumination less than 100 lux. fed fresh oysters, squid, frozen Nereid and other bait, bait cast day for about 10% of the weight of shrimp .
