The three combinations are described in detail below with reference to the drawings.
The first mode is as follows: a pump-pump combination. The combination can be seen in fig. 1, which shows that two multi-stage pumps 1 are combined together, each pump comprises a pump housing, a pump shaft and bearing bodies 2 at two ends of the pump shaft, one end of the pump shaft is connected with a driver to be driven by the driver to rotate, an inlet 3 and an outlet 4 are arranged on each pump housing, and the two pumps share the pump shaft, the bearing bodies and the driver. The combination only needs one drive, and a set of pump shaft and bearing body are shared, so that the equipment cost is reduced; one device outputs two parameters; after the two pumps are combined into a whole, the occupied area can be reduced relative to the two pumps. The directions of the flange interfaces of the inlet and the outlet of the pump are arranged according to the actual situation.
In order to balance the axial force of the pumps, the axial directions of the fluids of the two pumps are opposite, namely the two pumps need to be arranged in a mode of middle inlet and two ends outlet or in a mode of two ends inlet and two ends outlet. Namely, the inlet of each pump is positioned at one end far away from the other pump, and the outlet is positioned at one end close to the other pump; or the outlet 4 of each pump is at the end remote from the other pump and the inlet 3 is at the end close to the other pump (this arrangement is shown in figure 1).
The second mode is as follows: a pump-turbine combination. The combination can be seen in fig. 2, which shows that it comprises a pump 1 and a turbine 5 combined together, the pump 1 and the turbine 5 each comprise a pump housing, a pump shaft and a bearing body 2 at both ends of the pump shaft, one end of the pump shaft is connected with a driver to be driven by the driver to rotate, the pump housings of the pump 1 and the turbine 5 are provided with an inlet 3 and an outlet 4, and the pump shaft, the bearing body and the driver are shared by the pump and the turbine.
