进口多级离心泵美国阿卡迪亚品牌

进口多级离心泵Product Description:

A stable static component structure. The static component includes a sealing ring, a guide vane sleeve, a middle section, a guide vane, a throttling bushing and a large end cover. The guide vane sleeve and the guide vane are spot welded together after assembly. The sealing ring and the middle section are spot welded together after assembly. The inner wall of the inner hole at the liquid inlet of the throttling bushing is provided with a first annular groove, and the section of the first annular groove is rectangular. Compared with the prior art, the inner holes of the sealing ring, guide vane sleeve and throttling bushing are processed into a plurality of continuous rectangular grooves with certain spacing and depth. The first type is to increase the throttling length, reduce the gap leakage between the dynamic and static components, so as to provide sufficient flow when the liquid enters the long and narrow radial gap, ensure the reliable operation of the balance mechanism, and then improve the reliable stability of the centrifugal pump operation.

进口多级离心泵characteristic:

In the industrial use of centrifugal pumps, in order to meet the different requirements of users' flow, head and other parameters, the efficient and stable operation of centrifugal pumps under various working conditions is also very important. The radial clearance between the rotating components and static components of traditional centrifugal pumps exists to ensure the safety of pump operation and reduce the internal leakage of the pump. The clearance size will be slightly different according to the different operation fields and transmission media. The existence of these radial clearances makes the structure of multi-stage centrifugal pump supported by two bearings become a multi bearing support structure in the liquid delivered, which improves the wet critical speed of the centrifugal pump rotor and increases the rigidity of the rotor. However, the inner holes of the static components of the traditional multi-stage centrifugal pump and the rotating components are all smooth holes. Although it is convenient for processing, it is weak to adapt to the stability of the multi-stage centrifugal pump under variable operating conditions.

进口多级离心泵Principle:

进口多级离心泵The inner holes of the sealing ring, guide vane sleeve and throttling bushing are processed into a number of continuous rectangular grooves with certain spacing and depth. This type first increases the throttling length, reduces the gap leakage between the dynamic and static components, and improves the efficiency of the multi-stage centrifugal pump. Second, the existence of the rectangular throttling groove improves the cross-linking stiffness of the liquid between the dynamic and static components, which is equivalent to improving the stiffness of the rotor support, And then improve the stability of the rotating components under various operating conditions. In addition, at the inlet of the fit clearance between the throttle bushing and the balance drum, 36 additional φ 6 through holes distributed in the circumferential direction, which allows sufficient flow when the liquid enters the long and narrow radial gap, so as to ensure the reliable operation of the balance mechanism and improve the reliable stability of the centrifugal pump.
