Detailed Embodiment
[0018] The present utility model will be specifically described below with reference to the drawings. As shown in the attached Figure 1 figures, a multi-outlet multi-pressure fire pump includes a pump box 1. The pump box 1 is a box body with a detachable upper cover. Moving wheels 2 are installed at the four corners of the lower part of the pump box 1. A pull rod 3 is fixedly installed on one side of the pump box 1. The pump box 1 is installed with a storage tank assembly 4 and a flow splitting pump assembly 5.
[0019] In this embodiment, in combination with the attached Figure 2As shown in the figure, the storage tank assembly 4 includes a first storage tank 41, a second storage tank 42, a third storage tank 43, and a fourth storage tank 44 arranged in sequence. Pressure gauges 45 are fixedly installed at the detection ports of the first storage tank 41, the second storage tank 42, the third storage tank 43, and the fourth storage tank 44. The pressure gauges 45 are used to display the pressure. Drain valves 46 are installed at the outlets of the first storage tank 41, the second storage tank 42, the third storage tank 43, and the fourth storage tank 44. A spray pipe 47 is installed at each drain valve 46. When extinguishing a Class A fire is required, the drain valve 46 is opened so that the fire extinguishing substance in the first storage tank 41 is discharged through the spray pipe 47. The shunt pump assembly 5 includes a booster pump 51. A four-way pipe 52 is installed at the outlet of the booster pump 51. Check valves 53 are installed at the four outlets of the four-way pipe 52. The multiple check valves 53 are fixedly connected to the inlets of the first storage tank 41, the second storage tank 42, the third storage tank 43, and the fourth storage tank 44 respectively.
