进口卧式多级离心泵-美国阿卡迪亚品牌

进口卧式多级离心泵Product description:

The middle support is a water lubricated ceramic bearing structure, including a pump shaft, and both sides of the pump shaft are provided with a front stage impeller and a rear stage impeller, which rotate with the pump shaft; Guide vane, middle section, connecting screw, ceramic bearing II, ceramic bearing frame, anti rotation pin I and sealing rubber ring are stationary parts, which greatly reduces the complexity of the equipment and improves the economy of the equipment; The lubrication mechanism of the bearing is still hydrodynamic bearing. When the equipment is started and stopped, the moving and static parts of the bearing are still worn. The matching part of the moving and static parts of the bearing structure is made of the preferred ceramic material, which is wear-resistant and high temperature resistant. At the same time, it can produce a special reaction product with water. This reactant has the role of protection and lubrication, greatly improving the safety of the equipment when starting and stopping.

进口卧式多级离心泵characteristic:

Horizontal multistage centrifugal pumps are widely used in power plants, petroleum, chemical industry and other fields. With the increase of equipment outlet pressure in the application field, the efficiency of the entire operation system is improved. Users put forward higher requirements for the outlet pressure of multistage centrifugal pumps. With the increase of pressure, the increase of the number of stages of multistage centrifugal pumps can effectively improve the pump efficiency. However, with the increase of the number of stages, the bearing span at both ends of the bearing increases, Higher requirements are put forward for the stability of the pump. Generally, the horizontal multi-stage centrifugal pump still adopts the bearing support type at both ends. The lubricating meson is lubricating oil, and the lubricating form is forced lubrication with pressure oil or oil slinger lubrication. In this way, the stability and reliability of the pump during operation are greatly reduced, resulting in friction between dynamic and static parts, causing pump vibration

进口卧式多级离心泵Principle:

The horizontal multistage centrifugal pump is supported by a water lubricated ceramic bearing structure in the middle, including the pump shaft, which is equipped with a front stage impeller and a rear stage impeller. Guide vanes, middle sections, connecting screws, ceramic bearings, ceramic shafts, ceramic bearing frames, anti rotation pins, anti rotation pins and sealing rubber rings are set between the front stage impeller and the rear stage impeller, and the front stage impeller, ceramic bearings, rear stage impeller and anti rotation are all assembled on the pump shaft, rotating with the pump shaft; The guide vane, middle section, connecting screw, ceramic shaft, ceramic bearing frame, anti rotation pin and sealing rubber ring are stationary parts and form a closed streamlined cavity to ensure that the meson from the outlet of the front stage impeller flows evenly into the inlet of the rear stage impeller. The front stage impeller of this structure is assembled onto the pump shaft by tightening force, and then installed into the guide vane and middle section in turn. Two sealing rubber rings are installed into the sealing ring groove in the ceramic bearing frame, Install the ceramic bearing frame into the front stage middle section together with the ceramic bearing frame, and connect and fix the ceramic bearing frame and the middle section with connecting screws; The ceramic bearing and ceramic bearing are respectively installed into the pump shaft and ceramic bearing frame, and fixed with anti rotation pin and anti rotation pin. The ceramic bearing is fixedly connected to the pump shaft through the anti rotation pin, and the ceramic bearing is connected to the ceramic bearing frame through the anti rotation pin. Next, install the middle section and the rear stage impeller close to the rear stage impeller.
