工程を必要とする。A conventional vanillel type multi-stage turbo pump will be explained with reference to FIGS. 1 and 2. Figure 1 is a vertical cross-sectional view of a conventional barrel-type double-stage turbo pump, and Figure 2 is a cross-sectional view taken along line II-l in Figure 1. A balancing mechanism 2 is provided on the side opposite to the suction side of the mechanism 1. The leakage water from this balancing mechanism 2 is collected by a return pipe 5 passing between the inner casing 3 and the outer casing 4, or by a return pipe 5' passing outside the outer casing 4.
It is returned to the suction side 6 of the pump. Both ends of these return piping 5, 5' are fixed and the heat capacity is small, so
In the case of a pump for high-temperature liquids, the return piping 5.5' and its fixed parts are likely to suffer thermal fatigue due to thermal stress when the load suddenly changes, and vibrations during the operation of the broken pump can cause forced vibrations and vibrations in the return piping 5,5'. Resonance is likely to occur, and to prevent fatigue failure due to this, #j
This requires a complicated process, requiring unreliable distribution routes and special piping fixing methods.

される効果を有する。In order to solve the above-mentioned problems, the present invention has a structure in which an internal casing (e) is provided with a flow path for returning "leakage water" from a balancing mechanism that offsets the thrust load generated on the pump's rotor to the suction side of the pump. The present invention provides a versil type multi-stage turbo pump characterized by the following: In other words, a flow path is provided in the internal casing to return leaked water from the balancing mechanism to the suction side of the pump, so no return piping is required. This has the effect of eliminating the possibility of accidents due to fatigue failure of the return piping and omitting complicated processes.
