EPRV1-16-5.00-0-24DGHSN三螺杆泵选型步骤及注意事项首先要准确了解HSN三螺杆泵的实际工作参数，如压力、流量、介质的工作温度及介质在工作温度下的粘度、介质有无润滑性、腐蚀性等；根据介质在工作温度下的粘度初步选择泵的转速，一般粘度小于3mm2/s，选择n=145r/min比较适合，当粘度大于3mm2/s，请慎重考虑泵的必需汽蚀余量，以免泵产生振动；从泵的性能表上，按所需流量、压力等参数初步选择泵的规格；从泵的必需汽蚀表（P15）上，根据泵的规格、转速、粘度查出泵的必需汽蚀余量NPSHr值；如果泵的必需汽蚀余量NPSHr值小于管道装置的汽蚀余量NPSHa值，那么泵选型正确；如果泵的必需汽蚀余量NPSHr值大于管道装置的汽蚀余量NPSHa值，则要选择大一档的泵或是降低转速，并重新校合NPSHr值。
