进口多级离心潜水泵美国阿卡迪亚品牌

进口多级离心潜水泵Product Description: The utility model comprises a base assembly, a multi-stage guide vane assembly and a motor assembly in series through a connector. The motor assembly is composed of a pump body and a DC motor. The pump body is provided with a waterproof motor cavity and a flow channel, one end of the flow channel is provided with a water outlet, the DC motor is installed in the waterproof motor cavity, and a first dynamic seal is arranged between the motor shaft and the waterproof motor cavity; The multi-stage guide vane assembly is composed of more than one group of guide vane units, and each group of guide vane units includes impeller and guide plate; The base of each stage of the impeller is connected in series with the base of the motor stage, and the guide vane assembly is connected with the side of the motor stage, and the guide vane assembly is connected with the base of the motor stage in series.进口多级离心潜水泵 The obtained high-pressure pressure relief detachable multistage centrifugal submersible pump has the advantages of convenient disassembly and maintenance, small volume and good sealing performance. It is suitable for various high-pressure and narrow service environments. characteristic: The multi-stage submersible pump for well use mostly adopts the form of connection between the integrated pump body and the motor. When repairing the impeller and other parts inside the pump body, the pump body needs to be completely disassembled, which is difficult to maintain, and the pump body generally contains an integrated cover, resulting in the large and bulky volume of the submersible pump, high manufacturing and installation cost, and difficult to use in a narrow environment. In practical use, the traditional multi-stage pump mostly relieves pressure through the gap between the shaft and the impeller, When there are many liquid impurities, it is also easy to have insufficient pressure relief, resulting in water inflow to the motor. Principle: In order to facilitate processing and installation and prevent high-pressure liquid from penetrating into the waterproof motor cavity, the pump body is composed of gland, front cover, pump shell and rear cover. 进口多级离心潜水泵The pump shell is a double-layer annular shell, and the side wall is provided with a flow channel. The motor is installed in the middle of the pump shell and completely isolated from the flow channel. The front cover and rear cover are sealed and fixed at both ends of the pump shell to form a waterproof motor cavity. A bearing and a first dynamic seal are arranged between the front cover and the motor shaft, and the bearing is located in the waterproof motor cavity; Both ends of the gland are respectively connected with the front cover and the multi-stage guide vane assembly. A second dynamic seal and a leather cup are arranged between the gland and the motor shaft. A high-pressure relief hole connecting the motor shaft and the outside is arranged in the radial direction of the gland. One end of the high-pressure relief hole is arranged between the second dynamic seal and the leather cup.
