Be communicated with vacuum pumping device to air in fire water pump as the preferred outlet pipe of structure.Vacuum pumping device comprises tail gas fluidic device and valve; Described tail gas fluidic device comprises the second straight length and second pipeline section that is interconnected, and is provided with the suction port that connects second nozzle and the second air chamber that is communicated with second pipeline section in the second straight length; Described the second straight length is provided with suction port one end and is communicated with outlet pipe, and the second straight length the other end is communicated with atmosphere by exhaust nozzle, and second pipeline section connects fire water pump by tracheae.This kind vacuum pumping device has thoroughly shielded the history that traditional fire water pump need to be joined vacuum pump, and utilizes tail gas to realize vacuumizing of fire water pump, has not only saved the device fabrication cost, and has greatly reduced the weight of whole fire-protection equipment, is convenient to mobile.The concrete use flow process of this kind vacuum pumping device is for opening valve, tail gas by the suction port in the second straight length by second nozzle through exhaust nozzle discharged to atmosphere, utilize jet current principle to form negative pressure at the second air chamber, with the air in fire water pump by tracheae through exhaust nozzle with tail gas discharged to atmosphere, realize vacuumizing of fire water pump.
Be provided with valve between tracheae and fire water pump to control the switch that vacuumizes for fire water pump.Be provided with one-way valve in second pipeline section, prevent that tail gas is strayed into tracheae and affects the effect that vacuumizes.
Movement for the ease of fire water pump on space form, the fire water pump downside is provided with framework, framework is connected with respectively pulley and is provided with handle at side in the bottom, make fire water pump not only efficiently rolling type move, and can realize the movement of soaring by the mode that the handgrip handle lifts, the fire water pump that improves greatly is for the adaptive capacity of landform.
Described handle comprises the axostylus axostyle of handle body and connecting frame, and the axostylus axostyle periphery is overlapped respectively the sleeve that spring and connecting handle body are arranged; The folding and unfolding use that sleeve and axostylus axostyle latch are connected and are convenient to handle, the occupancy rate of the saving device space.
The present invention controls the ejection fire water of fire pump discharge mouth or foam fire-fighting liquid by COMM communication, realization difference according to burning things which may cause a fire disaster on the basis of same fire water pump is switched different extinguishing agents fast, expanded greatly the application of single fire water pump, alleviate the overall weight of equipment, improved fire extinguishing performance.
