Problems solved by technology

The failure of the water pump due to improper setting and maintenance will inevitably affect fire fighting and rescue, causing unnecessary losses
At present, when the water pump is used for on-site fire fighting, due to the water supply energy of its own water pump, the flow pressure is too high or too low from time to time, which affects the effect of fire extinguishing.

Embodiment Construction

[0008] The present invention will be further described below via accompanying drawing:

[0009] as attached figure 1 As shown, the fire-fighting water pump flow pressure regulating device is provided with a hydraulic pressure gauge 2 connected in series with the fire-fighting water pump 1, and the fire-fighting water pump 1 is attached with a stabilizing pump 3 arranged along the water delivery pipeline independent of its central processing unit Same as the wireless control transfer station 4 , the wireless control transfer station 4 is connected to the wireless controller 5 .

[0010] By setting the water pressure gauge 2 connected in series with the fire-fighting water pump 1, the fire-fighting water pump 1 is attached with a stabilized pressure pump 3 arranged along the water delivery pipeline independent of its central processor and a wireless control transfer station 4, and the wireless control transfer Station 4 turns on wireless controller 5 . In this way, the stabili...

Abstract

Provided is a fire pump flow pressure-adjusting device. A water pressure gage connected with a fire pump in series is arranged, the fire pump is additionally provided with a stabilized pressure pump and a wireless control transfer station which are independent to a central processor of the fire pump and arranged along a water supply pipeline, and the wireless control transfer station is communicated with a wireless controller. Therefore, flow pressure stability can be dynamically guaranteed, and fire extinguishment effect is improved.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a flow pressure regulating device for a fire water pump. Background technique [0002] The fire-fighting water provided by most fire-fighting water sources needs to be pressurized by fire-fighting water pumps to meet the requirements for water pressure and water volume when extinguishing fires. The failure of the water pump due to improper setting and maintenance will inevitably affect fire fighting and rescue, causing unnecessary losses. And at present, when the water pump is on-site fire-fighting, due to the left and right of the water supply energy of the self-water pump, the defect that the flow pressure occurs from time to time is too high or too low, which affects the effect of fire extinguishing. Contents of the invention [0003] The present invention provides a fire-fighting water pump flow and pressure regulating device. By setting a hydraulic pressure gauge ...
