Check-valves 5 is connected, and pressure relief pipe 6, the end of the pressure relief pipe 6 and 1 top-side of self-sucking pot are communicated on export pipeline 4
The relief hole 7 opened up is connected, and is also provided with gas vent 8 and water inlet pipe road 9, while self-sucking pot 1 on the top of the self-sucking pot 1
Bottom end offer drain hole 10,
The pump housing 2 includes ontology 11, and ontology 11 is connected with pump cover 12, and pump cover 12 is then connected with bearing housing 13, in axis
Holding rotational support in case 13 has impeller shaft 14, and one end of impeller shaft 14 is located at outside bearing housing 13, and the other end is then connected with impeller
15, and the impeller 15 is located at ontology 11 and pump cover 12 is formed by cavity, be additionally provided on bearing housing 13 oily window 16,
Breather plug 17 and hanging ring 18, while lubricating cup 19 is provided in bearing housing 13, it is mechanical equipped with packaging type with 14 phase of impeller shaft
Sealing mechanism 20.
The utility model compared with the existing technology, has the advantages that
The compound centrifugal pumps of the achievable high efficiency self suction of this kind of structure type, simple in sturcture, ingenious in design, layout is closed
Reason, it the problems of during restarting, designs a kind of special combined type pump housing knot for conventional centrifugal pump
Water filling port is arranged on top, to greatly reduce the difficulty of self-sucking pot entrance water suction, makes in its inner cavity by structure, its self-sucking pot
Required vacuum level requirements substantially reduce, thus require also corresponding reduce for the pressure condition of medium source in front of self-sucking pot；Together
When in the side of self-sucking pot be also provided with relief hole, this relief hole is connected by the pipeline between pipeline and pump housing outlet, this
Kind of design can the pressure of pump body after active balance termination of pumping, the pressure in pressure and export pipeline inside self-sucking pot, together
When can also allow and keep sufficient medium in self-sucking pot, complete secondary self-priming to facilitate.And the system of this compound centrifugal pumps
Make simple process, manufacturing cost is cheap, it can be said that it has a variety of advantages, answers particularly suitable for promoting in the art
With market prospects are very wide.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
Below in conjunction with Detailed description of the invention specific embodiment of the present utility model.It is a kind of as shown in Figure 1: to can be achieved efficiently certainly
The compound centrifugal pumps of suction, including self-sucking pot 1 and the pump housing 2, the outlet of 1 bottom end of self-sucking pot are connected with the arrival end of the pump housing 2, the pump housing
2 outlet end then passes through flange arrangement 3 and is connected with export pipeline 4, and the other end of export pipeline 4 then equally passes through flange arrangement 3
It is connected with check-valves 5, pressure relief pipe 6, the end of the pressure relief pipe 6 and 1 top side of self-sucking pot is communicated on export pipeline 4
The relief hole 7 that face opens up is connected, and is also provided with gas vent 8 and water inlet pipe road 9, while self-priming on the top of the self-sucking pot 1
The bottom end of tank 1 offers drain hole 10,
The pump housing 2 includes ontology 11, and ontology 11 is connected with pump cover 12, and pump cover 12 is then connected with bearing housing 13, in axis
