Description
Technical field
This utility model relates to defeated turning pump, particularly for defeated turn of fire-fighting class corrosivity foam or weak acid caustic corrosion
The defeated of the most defeated turn of raw material turns pump.
Background technology
At present, common defeated in market turns pump mainly has electronic foam defeated to turn pump, water wheels drive foam defeated turn pump, small-bore in
Combustion engine drives that foam is defeated turns the types such as pump.All there is various technological deficiency in the defeated pump that turns of existing various foam: electronic foam is defeated turns pump
Need to rely on power supply dumb motor-driven, not rain resistance, discharge pressure is little, and fed distance is short；Water wheels drive foam defeated turn pump weight big,
Discharge pressure is little, mobility is poor；Small-bore internal combustion engine drives the defeated pump that turns, and output flow is little, fed distance is short, and fuel tank is lasting
Working time is short.For fire-fighting work, these pumps all can bring great inconvenience in fire-fighting work.
Summary of the invention
For solving above-mentioned technical problem, this utility model provides that a kind of foam is defeated turns pump, and its volume is little, lightweight, work
Stablizing, flow is big, and pressure is big, and fed distance is long.
For solving above-mentioned technical problem, the technical scheme that this utility model provides is that a kind of fire-fighting foams is defeated turns pump, including
Fuel engines, change speed gear box, the pump housing, it is characterised in that described fuel engines is connected by the main shaft of clutch with described change speed gear box
Connecing, the travelling gear on the main shaft of described change speed gear box is connected transmission with the travelling gear on the output shaft of change speed gear box by chain；
The output shaft of described change speed gear box is connected with the driving shaft of the described pump housing by shaft coupling.
The travelling gear of the driving shaft of described change speed gear box with the gear ratio of the travelling gear on described output shaft of gear-box is
2:1。
The driving shaft of the described pump housing is positioned at the bottom of the described pump housing, and the driving shaft at the described pump housing is provided above driven
Axle, is respectively arranged with pitch wheel on described driving shaft and driven shaft.
Described gear is V-type gear.
Foam of the present utility model is defeated turns pump, changes the kind of drive that gear engages into chain transmission mode, greatly reduces
The fever phenomenon produced during gear long-term joggleword, improves stability and the stability in use of change speed gear box work, extends
Change speed gear box uses the time.By changing the position of pump housing driving shaft, change into the driving shaft being generally arranged at pump housing top arranging
In pump housing bottom, reduce the center of gravity of the pump housing, improve the stability of pump housing work.By the tooth on pump housing driving shaft and driven shaft
Wheel changes V-type gear into from ordinary gear, and owing to V-type inter-lobe clearance is big, angle is big, can form bigger draft in the running, add
The flowing of fast liquid foam, improves foam flow.

Fig. 1, foam is defeated turns pump contour structures schematic diagram.
Fig. 2, gearbox designs schematic diagram.
Fig. 3, pump housing driving shaft and driven shaft structural representation.
Detailed description of the invention
For technique scheme, now lift a preferred embodiment and combine diagram and be specifically described.Referring to Fig. 1 to Fig. 3,
The defeated pump that turns of fire-fighting foams of the present utility model includes fuel engines 1, change speed gear box 2, shaft coupling 3, the pump housing 4, wherein.
Fuel engines 1, is connected with change speed gear box 2 driving shaft by clutch 21.Clutch 21 is positioned at gear box casing 20
In.It is provided with driving gear 22 on change speed gear box driving shaft, is provided with output shaft of gear-box, in speed change in change speed gear box driving shaft side
It is provided with driven gear 23, driving gear 22 and driven gear 23 on case output shaft to be connected by chain 24.Driving gear with from
The gear ratio of moving gear is 2:1.Change speed gear box driving shaft and output shaft are bearing on gear box casing by bearing respectively.In this reality
In novel, use chain and gear drive to replace meshed transmission gear, reduce change speed gear box because of the heat energy of the generation that runs up,
Improve change speed gear box working time and job stability.
The pump housing 4, including housing 41, is provided with fast joint import in the front portion of housing 41, is provided with at the rear portion of housing and disappears
Water blocking tape snap joint exports.The bottom in sky portion is provided with pump housing driving shaft 42 in the housing, is provided above at pump housing driving shaft
There is pump housing driven shaft 43, pump housing driving shaft be provided with driving gear 44, pump housing driven shaft is provided with driven gear 45,
Driving gear and driven gear carry out power transmission with engagement system.The flute profile of driving gear and driven gear is V-type.Use
V-type gear, owing to space width and the angle changing rate of V-type tooth are big, when gear operation, can make foam output flow increase.The pump housing
All parts use corrosion-and high-temp-resistant stainless steel material make.Use driving shaft to be arranged on pump housing bottom, the pump housing can be made
Overall decentralization, improves stable and reliable operation.
Pump housing driving shaft is connected with the output shaft of change speed gear box by shaft coupling 3, drives the pump housing to operate by fuel engines.
Fuel engines, change speed gear box, the pump housing are respectively arranged with on rustless steel bracing frame, and the bottom of bracing frame is provided with universal wheel, side
Just the movement that the pump housing is overall.
The defeated pump that turns of fire-fighting foams of the present utility model, simple in construction, but overall structure is strong, and mobility is high, and due to
Center of gravity is low, produces heat energy few, and overall operation is more steady, more reliable；Owing to using V-type gear, output pressure is big, output flow
Greatly, fed distance is remote, longevity of service plurality of advantages of continuing a journey.
