Roots blower test run for the new installation overhaul or blower must be unused for a long time commissioning. Concrete steps are as follows 1, under no-load condition jog power switch Check the motor rotation direction. Indicating the direction of rotation required cooling shroud fan cooling water valve should be open. 2, starts 30 minutes after the air operation to check for abnormal vibration and heat generation should be shut down if unusual circumstances pinpoint the cause. 3, no-load operation, no abnormal situation gradually close the vent valve reaches the rated pressure to observe the fan temperature and vibration current, voltage is normal. 4, the operation of the process on a regular basis to check the oil temperature, ammeter, bearing temperature is generally 15 minutes to check again. 5, shutdown must first relief, load shedding and then finally closed cooling water park. Roots blower used in the breeding industry: a rectangular sink nursery facilities of its prawn nursery room nursery ponds usually made of fiberglass or concrete ponds blower uses a volume of 10 to 15 cubic meters of water must pass two nursery. to 4 times filtered, unicellular algae culture more stringent water treatment. heating boilers available or coal boilers, hot water circulating in a way. Roots blower inflated. Second, the selection of healthy seed shrimp cultivation without injury, weight 50 ~ 60 grams shrimp species to male and female ratio of 1 to 1: 1 into the flume stocking stocking density of 4 to 5 / m blower manufacturers, wholesale, water temperature 26 ~ 27 ℃ 33 to 35 per thousand salinity, each. Japanese keeper pool of about 50% water change blower and blower to inflate wholesale phone, stocking pond covered with black shading, the pool is less than 100 lux illumination. fed fresh oysters, squid, frozen bait such as Nereis, Japan cast bait shrimp for about 10 percent of body weight.
