At present for water inlet and the water outlet of fire water pump, mainly rely on vane rotary, in volute, form negative pressure of vacuum extraneous hydraulic pressure is entered in volute, after the fast rotational pressurization by impeller, through outlet valve, discharge and form higher lift, carry out fire-fighting fire extinguishing.Certainly also there is fire water pump to adopt supporting vacuum pump to realize and vacuumize, obviously greatly increased the manufacture cost of fire water pump, and the volume of fire water pump inapplicable.Existing fire water pump its at vane rotary, volute inside to be formed to relative spended time of process of vacuum longer, for speedily carrying out rescue work in fire-fighting, wait special occasions how to reduce the time that impeller vacuumizes, realize water outlet and spray water to put out a fire fast and seem particularly important.Those skilled in the art have also adopted multiple technologies scheme for the quick water spray of realizing fire water pump, but effect is also not obvious, general gasoline, the diesel engine adopting of the power source of fire water pump also produced a large amount of tail gas in the process that power is provided simultaneously, has certain pollution of atmosphere and the waste of the energy.
The Chinese utility model patent patent No. 201020276448.3 discloses a kind of water sucking device of firefighting pump, comprise fire service pump, described fire service pump connects one end of suction sleeve, the other end access fire-water pond of suction sleeve, in described suction sleeve, connect supply pipe, the other end of described suction sleeve is provided with water suction bottom valve.This kind of fire service pump do not mentioned the air in quick discharge fire water pump volute, vacuumizes technological scheme or the technical clarification of diversion.
Model utility content
The utility model provides a kind of single gear fire water pump of energy-saving, high-lift, the tail gas diversion with quick jet power.
A kind of single gear fire water pump of tail gas diversion, comprise outlet valve, motor and the exhaust box for emission be located on volute, the main shaft of described motor is connected with driving gear by key pin, the driving gear driven gear that is connected with a joggle, driven gear center is connected with output shaft, output shaft outer end is provided with the impeller that is positioned at volute, and the corresponding intake pipe that is provided with airtight connection volute in impeller outside, is connected with tail gas water diversion apparatus on intake pipe tube wall.The utility model adopts tail gas water diversion apparatus by the air in volute, and that utilizes that tail gas attracts to discharge volute and impeller vacuumizes generation synergistic effect, has greatly shortened the water outlet discharge time of fire water pump, has realized the technical purpose of quick injection.
As the preferred tail gas water diversion apparatus of structure, comprise the straight length and the pipeline section that are interconnected, straight length one end is provided with suction port and connects the outlet pipe in exhaust box, the other end is provided with nozzle, nozzle is communicated with the air jet pipe that diameter is less than suction port, the outside of air jet pipe lower end is provided with the air chamber that is positioned at straight length, air chamber is by the pipeline communication valve of connecting branch section, and valve is communicated with intake pipe tube wall.This kind of tail gas water diversion apparatus utilizes tail gas to be injected in air chamber and forms vacuum, utilizes negative pressure that the air in intake pipe and volute is discharged fast, and then diversion enters impeller and realize the quick injection of fire water pump.
Described motor is installed in the frame of bottom, and frame is equipped with handle on four corners.Person easy to use is by handle fast moving fire water pump.
Described handle comprises the axostylus axostyle of handle body and connection frame, and axostylus axostyle periphery is overlapped respectively has spring and the sleeve that is connected the body of shaking hands; Sleeve and axostylus axostyle latch are connected and are convenient to the folding and unfolding use of handle, save the occupancy rate of the device space.
The utility model is by tail gas water diversion apparatus by the air in volute, and that utilizes that tail gas attracts to discharge volute and impeller vacuumizes generation synergistic effect, has greatly shortened the water outlet discharge time of fire water pump, has realized the technical purpose of quick injection.
