Description

Technical Field

[0001] This utility model relates to the field of fire pumps, specifically a new type of multi-unit fire pump. Background Technology

[0002] In firefighting, providing sufficient water pressure and volume is crucial to ensuring effective fire suppression. Current fire pump systems often use a single pump or a fixed combination of pumps, which is insufficient to meet the needs of complex and ever-changing fire scenes. This is especially true in high-rise buildings, large warehouses, or industrial parks, where factors such as water pressure loss, water source limitations, or the speed of fire spread can prevent a single pump from providing sufficient spray pressure, thus limiting fire suppression capabilities. In some fire scenes, a single pump cannot extinguish multiple fire sources simultaneously. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a novel multi-unit fire pump.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A novel multi-unit fire pump includes a base plate. Pump 1, Pump 2, and Pump 3 are fixedly mounted on the top of the base plate, equidistantly distributed from left front to right rear. The inlet end of Pump 1 is fixedly connected to Inlet Pipe 1, and Inlet Valve 1 is installed on Inlet Pipe 1. The inlet end of Pump 2 is fixedly connected to Inlet Pipe 2, and Inlet Valve 2 is installed on Inlet Pipe 2. The inlet end of Pump 3 is fixedly connected to Inlet Pipe 3, and Inlet Valve 3 is installed on Inlet Pipe 3. The outlet ends of Pump 1, Pump 2, and Pump 3 are respectively fixedly connected to Outlet Pipe 1, Outlet Pipe 2, and Outlet Pipe 3. Outlet Valve 1 is installed on Outlet Pipe 1, and Outlet Valve 2 is installed on Outlet Pipe 2. A third outlet valve is installed on the third outlet pipe. A first water supply pipe is connected between the first outlet pipe and the second inlet pipe. The left end of the first water supply pipe is fixedly connected to the first outlet pipe. The left end of the first water supply pipe is located below the outlet valve. The right end of the first water supply pipe is fixedly connected to the second inlet pipe. The right end of the first water supply pipe is located between the second inlet valve and the second water pump. A first water supply valve is installed on the first water supply pipe. A second water supply pipe is connected between the second outlet pipe and the third inlet pipe. The left end of the second water supply pipe is fixedly connected to the second outlet pipe. The left end of the second water supply pipe is located below the second outlet valve. The right end of the second water supply pipe is fixedly connected to the third inlet pipe. The right end of the second water supply pipe is located between the third inlet valve and the third water pump. A second water supply valve is installed on the second water supply pipe.

[0006] The beneficial effects of this utility model are:

[0007] This invention, through a series pressurization mode, can significantly increase the water pump's outlet pressure and spray height, enabling fire-fighting water to cover farther distances and higher positions, thereby improving fire-fighting efficiency.

[0008] The design of this fire pump allows for flexible adjustment of the working mode according to actual needs. Each pump can be used individually to extinguish multiple fire sources, or the outlet water pressure can be increased through a series pressurization mode. Attached Figure Description

[0012] like Figure 1-2 As shown: A novel multi-unit fire pump includes a base plate 1. Pump 2, Pump 3, and Pump 4 are fixedly installed on the top of the base plate 1. Pumps 2, 3, and 4 are equidistantly distributed from left front to right rear. The inlet end of Pump 2 is fixedly connected to Inlet Pipe 5, and Inlet Valve 6 is installed on Inlet Pipe 5. The inlet end of Pump 3 is fixedly connected to Inlet Pipe 7, and Inlet Valve 8 is installed on Inlet Pipe 7. The inlet end of Pump 4 is fixedly connected to Inlet Pipe 9, and Inlet Valve 10 is installed on Inlet Pipe 9. The outlet ends of Pump 2, Pump 3, and Pump 4 are respectively fixedly connected to Outlet Pipe 11, Outlet Pipe 23, and Outlet Pipe 35. Outlet Valve 12 is installed on Outlet Pipe 11, Outlet Valve 24 is installed on Outlet Pipe 23, and Outlet Valve 15 is installed on Outlet Pipe 35. A water outlet valve 16 is installed on the top. A water supply pipe 17 is connected between the water outlet pipe 11 and the water inlet pipe 27. The left end of the water supply pipe 17 is fixedly connected to the water outlet pipe 11. The left end of the water supply pipe 17 is located below the water outlet valve 12. The right end of the water supply pipe 17 is fixedly connected to the water inlet pipe 27. The right end of the water supply pipe 17 is located between the water inlet valve 28 and the water pump 23. A water supply valve 18 is installed on the water supply pipe 17. A water supply pipe 29 is connected between the water outlet pipe 23 and the water inlet pipe 39. The left end of the water supply pipe 29 is fixedly connected to the water outlet pipe 23. The left end of the water supply pipe 29 is located below the water outlet valve 214. The right end of the water supply pipe 29 is fixedly connected to the water inlet pipe 39. The right end of the water supply pipe 29 is located between the water inlet valve 310 and the water pump 34. A water supply valve 20 is installed on the water supply pipe 219.

[0013] When all water pumps need to operate independently, inlet valve 16, inlet valve 28, inlet valve 310, outlet valve 12, outlet valve 214, and outlet valve 316 can be opened, and delivery valve 18 and delivery valve 20 can be closed; water can then enter water pump 12, water pump 23, and water pump 34 through inlet pipe 15, inlet pipe 27, and inlet pipe 39 respectively, and be output through outlet pipe 11, outlet pipe 213, and outlet pipe 315.

[0014] If it is necessary to increase the outlet pressure or inlet flow of the water pump, for example, to increase the outlet pressure of water pump 23, close outlet valve 12 and inlet valve 28, open water supply valve 18, inlet valve 16 and outlet valve 24, start water pump 12 and water pump 23, and close water pump 34 and water supply valve 20. In this way, the water pressurized by water pump 12 will enter the inlet pipe 27 of water pump 23 through water supply pipe 17, thereby increasing the outlet pressure of water pump 12 through water pump 23.

[0015] Similarly, to increase the outlet pressure of water pump 4, close outlet valve 12, inlet valve 28, inlet valve 30 and outlet valve 24, and open water supply valve 20, water supply valve 18, inlet valve 16 and outlet valve 36, and start water pump 2, water pump 2, water pump 3 and water pump 4; in this way, the water passing through water pump 2 and water pump 23 will enter the inlet pipe 39 of water pump 4 through water supply pipe 219, and the water pressure will be further increased.

[0016] Depending on actual needs, pumps 1 and 2 and pump 2 and 3 can be used in a flexible combination, pump 2 and 3 and pump 3 and 4 can be used, or pumps 1 and 2, pump 2 and 3 and pump 3 and 4 can be used simultaneously.
