Detailed Implementation
[0021] 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.
[0022] Please see Figure 1 This utility model provides a technical solution: an integrated fire-fighting skid-mounted pump set, including fire pumps 5 symmetrically arranged on the skid-mounted pump set base 20. The inlet end of the fire pump 5 is connected to an inlet 1 via a fire-fighting open stem gate valve 2. The fire pump 5 is characterized by having an outlet pipe 11 connected to its outlet end. A silencer check valve 10 is arranged on the connecting pipe between the outlet pipe 11 and the fire pump 5. One end of the outlet pipe 11 is connected to a grooved equal-diameter tee 111, and the port of the grooved equal-diameter tee 111 furthest from the outlet pipe 11 is connected to a patrol valve. Pressure switches 112 are installed on the inspection pipe 13, the outlet pipe 11, and the trench equal diameter tee 111. The lower part of the fire pump 5 is isolated from the skid-mounted pump set base 20 by vibration damping pads. The pipe connecting one fire pump 5 and the outlet pipe 11 is a set of fire pipes. Two sets of fire pipes are symmetrically arranged on the skid-mounted pump set base 20, and one set of fire pipes is connected to the port of the trench equal diameter tee 111. The two sets of fire pipes are connected to each other, and fire hydrants 12 are connected to each other in the middle of the pipe. The middle pipe is connected to the return water pipe 16.
[0023] This utility model, through modular design, integrates the fire pump 5 and various pipelines onto the skid-mounted pump set base 20, simplifying the connection and installation steps of each component. This allows for rapid assembly and commissioning of the pump set, significantly shortening installation time and reducing labor costs. Simultaneously, the rational layout and maintenance access design make the inspection and replacement of each component more convenient, simplifying maintenance, improving maintenance efficiency, and reducing downtime. The compact structural design and rational arrangement of components minimize the footprint, making it suitable for more scenarios, including environments with limited space. The use of silencing devices and vibration isolation design significantly reduces operating noise and vibration, improving the comfort of the operating environment.
[0024] Reference Figure 1 and 3 As shown, in this embodiment, the inlet of the fire pump 5 is connected to the fire-fighting gate valve 2 via a flanged rubber expansion joint 3, and the outlet of the fire pump 5 is connected to a grooved concentric reducer 7 via a grooved flange 6. A grooved elbow 8 is connected to the upper part of the grooved concentric reducer 7, and the grooved elbow 8 is connected and fixed to a silent check valve 10. The flanged rubber expansion joint 3 prevents loosening of pipe connections due to vibration during the operation of the fire pump 5, improving the long-term stability of the entire pump system. The grooved connection design at the pipe joints facilitates installation and disassembly.
[0025] Reference Figure 1 , 3 As shown in Figure 4, in this embodiment, fire-fighting gate valves 2 for controlling the flow of water are installed on both the outlet pipe 11 and the fire-fighting pipe.

A vacuum gauge 4 is installed on the fire pump 5, and a grooved flow meter 21 for monitoring the flow rate is installed on the return water pipe 16. In practical applications, the control system can be installed in the electrical control box of the skid-mounted pump base 20, and the operating status of the pump unit can be monitored in real time using the vacuum gauge 4, pressure gauge 18, and flow meter. This makes the inspection and replacement of each component more convenient, reduces the complexity and difficulty of maintenance, improves maintenance efficiency, and reduces the risk of downtime due to malfunction.
[0026] Reference Figure 1 and 2 As shown in this embodiment, grooved butterfly valves 14 for controlling the on / off state of the pipelines are arranged on both the inspection pipeline 13 and the fire protection pipeline. A grooved pressure-holding and pressure-relief valve 15 is also connected to the inspection pipeline 13. The grooved butterfly valve 14 and the grooved pressure-holding and pressure-relief valve 15 can provide pressure stabilization and pressure relief protection for the pipeline, while facilitating daily control of the on / off state of the entire pipeline.
[0027] In this embodiment, a grooved gate valve 17 is connected to the return water pipe 16, and a reserved interface 19 is provided on the outlet water pipe 11 for connecting to a pressure stabilizing device. (Refer to...) Figure 1 and 2 As shown, the reserved interface 19 can be used with external pressure stabilizing equipment to ensure the pressure stability of the entire pump system, which is convenient for daily use.
[0028] Reference Figure 1 As shown in this embodiment, an adjustable bracket is fixedly installed on the skid-mounted pump unit base 20. The adjustable bracket has several mounting holes for mates with the pump unit system pipes and valves. The pipes and valves are installed on the adjustable bracket using fasteners that mate with the mounting holes. The bracket is made of high-strength steel, bent and welded, with a surface anti-corrosion treatment. It has good load-bearing capacity and corrosion resistance. The bracket is designed with multiple mounting holes to accommodate pipes and valves of different heights, and is secured with bolts to ensure the stability of the pipes and valves.
