本标准规定抽吸井中清水用长轴离心深井泵设计点性能。其性能范围:流量 3.2～1500m~3/h 扬程 15～300m1 泵型号型号由五部份组成,它们分别代表适用最小井径尺寸、泵型代号、流量、总扬程、级数。示例:2 泵的转向从驱动端看泵轴为逆时针方向旋转。3 设计点性能和主要尺寸应符合表规定。4 工作条件及制造技术按 GB443-78《离心深井泵技术条件》,试验方法及性能偏差应符合 GB3216-91《离心泵,混流泵,轴流泵和旋涡泵试验方法》。
This standard specifies the suction well water with long axis centrifugal deep well pump design point performance. Its performance range: Flow 3.2 ~ 1500m ~ 3 / h Head 15 ~ 300m1 Pump model consists of five parts, which represent the smallest borehole size, pump code, flow, total head, series. Example: 2 Pump Steering When viewed from the drive end, the pump shaft rotates counterclockwise. 3 Design point performance and the main dimensions should be consistent with the provisions of the table. 4 working conditions and manufacturing technology According to GB443-78 “centrifugal deep well pump technical conditions”, test methods and performance deviations should be consistent with GB3216-91 “centrifugal pump, mixed flow pump, axial flow pump and the vortex pump test method.”
