[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1 As shown, a novel integrated fire pump set structure includes two sets of outlet pipes, a test horizontal pipe 16, and an outlet horizontal pipe 23.

[0018] The water outlet pipeline includes a suction pipe 1, an outlet riser 9, and an outlet pipe 15, which are connected sequentially. The other end of the suction pipe 1 is connected to a water tank. A suction pipe gate valve 2, a vacuum pressure gauge 3, a filter A4, and a fire pump 5 are sequentially installed on the suction pipe 1. The filter A4 and the fire pump 5 are connected by a flexible joint A6-1 and an eccentric reducer 7. The other end of the fire pump 5 is connected to the suction pipe 1 via a concentric reducer 8. A pressure gauge 10, a check valve 11, an outlet pipe gate valve A12, a water hammer eliminator 13, and an outlet pipe gate valve B14 are sequentially installed on the outlet riser 9. The outlet riser 9 and the pressure gauge 10 are connected by a flexible joint B6-2.

[0019] The test horizontal pipe 16 is installed between the check valve 11 and the outlet pipe gate valve A12 of the two sets of water outlet pipes. A horizontal pipe test gate valve A17, a system test fire hydrant 18, and a horizontal pipe test gate valve B19 are sequentially installed on the test horizontal pipe 16. A test flow line 20 is installed between the horizontal pipe test gate valve A17 and the system test fire hydrant 18. A test gate valve 21 and a flow testing device 22 are installed on the test flow line 20.

[0020] The horizontal outlet pipe 23 is located between the outlet gate valves A12 and B14 of the two sets of outlet pipes. A pressure switch 24 is installed on the horizontal outlet pipe 23. A pressure relief pipe 25 is also installed on the horizontal outlet pipe 23. A rising stem gate valve 26, a filter B27, and a pressure relief valve 28 are sequentially installed on the pressure relief pipe 25.

[0024] When testing or maintenance is required, the flow of water in the water pipe is controlled by opening and closing the valves A12, B14, A17, B19, 21, and 26, facilitating the maintenance of the water pump. The pressure switch 24 detects the pressure of the water in the pipe. When the pressure reaches the rated value, the pressure relief valve 28 opens to reduce the pressure in the pipe to the normal range. The flow test device 22 detects the flow rate of the water. The water in the flow test pipeline 20 and the pressure relief pipeline 25 flows back to the water tank through the test return pipeline 29.
