进口回流轴流泵美国阿卡迪亚品牌

进口回流轴流泵Product Description:

The utility model comprises a vertical pipe and a water outlet elbow connected to the top of the vertical pipe, the internal rotation of the vertical pipe is connected with a pump shaft, the internal part of the vertical pipe and the surface of the pump shaft is provided with a backflow prevention mechanism, the surface of the vertical pipe is provided with a damping mechanism, the backflow prevention mechanism includes a fixed rod, the internal part of the fixed rod is provided with a through hole suitable for the pump shaft, and the inner wall of the through hole is fixedly connected with an annular ring, which relates to the technical field of axial flow pumps. The high-efficiency anti backflow shock absorption axial-flow pump, with the movable cover plate in the state of being lifted up when the water is normally transported, can be covered when the water is refluxed. Such a setting can prevent the water from refluxing and lay a foundation for the subsequent normal water transportation. At the same time, when the pump body generates a large vibration force, the vibration force is effectively reduced through the shock absorption mechanism to reduce wear and prolong the service life of the device.

进口回流轴流泵characteristic:

Axial flow pumps are vertical, horizontal, inclined and through flow pumps that transmit liquid along the axial direction by the force generated by the blades of the rotating impeller. The impeller of the axial flow pump is equipped with 2 ? 7 blades, which rotate in the cylindrical pump shell. The pump shell at the upper part of the impeller is equipped with fixed guide vanes to eliminate the rotating movement of the liquid, turn it into axial movement, and convert the kinetic energy of the rotating movement into pressure energy. The axial flow pump is usually a single-stage type, A few of them are made into two-stage type, with a large flow range of 1.8-3.6 million m3 / h and a lift of less than 20 m. axial flow pumps are generally vertical, with the impeller submerged under the water. There are also horizontal or inclined axial flow pumps. When the impeller of small axial flow pumps is installed above the water surface, it is necessary to use the vacuum pump to exhaust and divert water. The blades of axial flow pumps are divided into fixed and adjustable structures.

进口回流轴流泵Principle:

The axial flow pump can transport water from low to high by the high-speed rotating power of the impeller. In the actual use process, when the water pressure at high places is too large, the backflow phenomenon will occur inside the pump body, affecting the normal transmission of water. At the same time, the pump shaft and impeller will produce large vibration during the operation process. The bottom of the pump body is easy to be worn due to vibration between the contact surfaces, reducing the service life of the pump body.
