Powerful suction fan advantages: 1, low investment, low energy consumption. Cooling fan breeding hens same rate, about one-sixth of conditioning time investment, about one-tenth of the air conditioning running costs; 2, the cooling effect is significant, the temperature dropped about 28 degrees can match the body temperature if wells with water as a source of better breeding tank with a fan, air-conditioning effect can be compared; 3, the air is fresh, moist. Air Cleanliness 99%; normal stop: the unit normal shutdown procedure operates as follows. a, gradually open the vent valve (or exit the bypass valve), and gradually close the exhaust valve. b, and gradually turn it into throttling door to 20 ~ 25 ° [2]. c, press the stop button Huludao farming fans, and note whether the shutdown process anomalies. d, the unit stops after 5 ~ 10min, or to stop the oil bearing temperature drops below 45 ℃. For a floating ring seal breeding unit fan, seal oil pump must continue until the body temperature is below 80 ℃ up. After the crew stopped within 2 to 4 hours should be regularly moving rotor plate 180 °.
