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, 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 units with a floating ring seal, seal oil pump must continue farming fans, until the body temperature is below 80 ℃ up. After the crew stopped within 2 to 4 hours should be regularly moving rotor plate 180 °. Adjustable inlet vane inlet vanes regulate farming fans, by adjusting the blade suction impeller flow direction changes, changes in the performance curve of the fan. Air-conditioning fan regulate the flow of imports are convoluted, inlet guide vane angle can be achieved for all operating conditions when the performance curve below zero; while a negative regulator of imported livestock breeding convoluted flow fan, can increase the fan pressure and flow, but the adjustment range has certain limits. Because adjustable inlet vanes with a wide adjustment range and higher wholesale fan farming economy, and to achieve automatic adjustment, therefore, are widely used for air-conditioning fan. Livestock farming fans, Qingzhou Minhua temperature control equipment, Qingyun farming fan community is provided by China Qingzhou temperature control equipment plant.
