About the calculation of the gas flow filled in the test cover, with the reference of the relative materials, the study is carried out in comparison with the various pressure units, the evolution and derivation of the calculation formula are given here. And the period of the detail derivation...
Since overlarge axial force can damage the pump, accurate calculation formula of axial force on pump is very significant. The traditional formula is based on the assumption that the leakage amount of the pump is zero and the angular speed of fluid in the pump chamber rotates at half the ...
In steady state, the evaluation methods of vibration are mainly intensity, that is, root mean square value, and the calculation formulas will be given in Section 3.5. The main evaluation criterion of pressure fluctuation is peak-to-peak value, which can clearly obtain the characteristics of ...
The calculation process of the axial units involves two methods. The first one allows the assumed hydraulic parameters to be obtained by means of recalculating the existing and investigated pumps. As was mentioned in [12], labyrinth pumps are subjected to the law of hydraulic similarity. This app...
