HSN三螺杆泵选型步骤及注意事项
HSN three screw pump selection steps and matters needing attention
1、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；
1, we should accuray understand the actual working parameters of the HSN three screw pump, such as the temperature and medium pressure, flow rate, medium viscosity at operating temperature, medium with and withoutlubrication, corrosion resistance;
2、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300mm2/s，选择n=1450r/min比较适合，当粘度大于300mm2/s，请慎重考虑泵的必需汽蚀余量，以免泵产生振动；
Preliminary selection of pump 2, according to the media at the operating temperature of the viscosity of thespeed, the general viscosity is less than 300mm2/s, n=1450r/min is more suitable, when the viscosity is greater than 300mm2/s, please consider carefully pump necessary NPSH, lest the pump vibration;
3、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；
3, from the pump performance table, according to the required flow and pressure, the preliminary selection ofpump size;
4、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；
4, from the pump required NPSH table （P15）, according to the size, speed, viscosity pump to pump necessary NPSH NPSHr value;
5、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。NPSHr ≤ NPSHa+K（一般情况安全裕度 K取0.3—0.5m）
5, if the pump necessary NPSH NPSHr value is less than the pipeline device of NPSH NPSHa value, then the pumpselection is correct; if the pump necessary NPSH NPSHr value is greater than the pipeline device of NPSH NPSHa value, then to the choice of a pump or reduce speed, and re adjustment of NPSHr value. NPSHr ≤ NPSHa+K（general safety margin of K 0.3 - 0.5m）
6、选定泵的规格后，在对应的粘度下，从表中查出此规格泵在工作压力下△P下的流量与轴功率N1，选配电机功率N2，N2 ≥ K·N1。N1（Kw） ≤5 5＜N1≤10 10＜N1≤50 ＞50K 1.25 1.2 1.15 1.1
6, the selected pump specifications, in the corresponding viscosity, from the table to identify the specifications of the pump in the work pressure △ P under the flow and shaft power N1, matching motor power N2, N2 ≥ K · N1. N1（Kw） ≤ 55 < N1 < 1010 < N1 > 50K 1.25 1.2 1.15 1.1 50
7、用户选定泵后，根据泵的规格与电机的机组配套尺寸进行基础施工设计，进出口管道必须与泵的进出口相匹配。
7, the user selected pump, foundation construction design according to the unit size specification of pump and motor, import and export pipeline must match the import and export of pumps.
