Seven, assembly, disassembly assembly sequence: 1, "0" ring seal mounted on the oil chamber, Yuanyang County N, install improved subassembly, and then loaded on the stator unit installed; 2, mounted on a good motor cover, and cable holder assembled, and then loaded on to mention the screw rings and; 3, mounted on the cable jacket, phase sequence identification card and a ground plate; 4, anti-head installed mechanical seal, the pump cover, mechanical seal seat; 5, fitted the wear sleeve and oil seal; 6, mounted on the key and Vice impeller, the pump cover and replace the "0" ring; 7, mounted on the impeller and the impeller plate, and then install the pump; 8, loaded progress water stand, NSQ100-50-37 pumping sand pumps, wheel? And sand suction plate; 9, the rubber grommets and mixing impeller, NSQ400-15-37 pumping sand pump, then replace the stand; 10, reference may be disengaged when the assembly sequence, reversed. 4. The process produces cavitation bubble and the bubble burst so that the flow components subjected to the process of destruction of the pump is the pump in the cavitation process. After the pump cavitation flow components in addition to produce damaging effects, but also produce noise and vibration, NSQ100-60-45 pumping sand pump and cause pump performance decline, severe disruption of liquid pump will not be normal jobs. NSQ400-15-37 pumping sand pumps | Yuanyang N | submersible pumping sand pump is provided by the Shijiazhuang-Pump Co., Ltd. faction. Shijiazhuang-school Pump Co., Ltd. (www.shipaipump.com) strong, credible, and other industries in other Shijiazhuang, Hebei accumulated a large number of loyal customers.
