Abstract
The tunnel pneumatic water pump comprises a shell, a water inlet, a water outlet, an impeller and an impeller shaft, and is characterized by further comprising a partition plate, a rotor shaft, an upper bearing, a lower bearing, blades connected with the rotor, an air inlet and an air outlet, wherein the rotor shaft and the impeller shaft are connected into a whole. The compressed air is used as power, the use is safe and reliable, and the defects that an electric water pump used in a tunnel is easy to burn a motor and explode when meeting gas are overcome.
Description
The utility model relates to a kind of suction engine, particularly a kind of wind-driven water pump that is used for the tunnel.
At present, electric water pump commonly used is got rid of ponding in the tunnel.This electric water pump has housing, water intake, water outlet, motor, impeller, by the rotation of driven by motor impeller, produces negative pressure in the pump housing, makes water enter the pump housing by water intake, is discharged by water outlet.To there be the special messenger to look after during this pump work, hinders water pump in order to avoid water is drained idle running, easily electric leakage in wet environment, motor often burns out.Because motor has electrical spark, at mine and be equipped with use in the tunnel of inflammable explosive article very dangerous.Do not have in the open air under the condition of generating equipment and can't use, cause ponding in time not get rid of, influence the proper functioning in the tunnel.
The purpose of this utility model is, uses the problem that exists to improve in the tunnel at electric water pump, and a kind of tunnel wind-driven water pump that is power with pressurized air, draws water effective, safe and reliable is provided.
Composition of the present utility model comprises housing, water intake, water outlet, impeller, impeller shaft, it is characterized in that also comprising dividing plate, rotor, rotor shaft, upper bearing (metal), lower bearing, the blade of connection rotor, suction port, air outlet, rotor shaft and impeller shaft connect as one.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model overall structure vertical profile schematic representation.
As shown in Figure 1, composition of the present utility model comprises housing 7, water intake 8, water outlet 12, impeller 6, impeller shaft 13, dividing plate 14, rotor 16, rotor shaft 17, upper bearing (metal) 1, lower bearing 5, connects blade 15, suction port 4, the air outlet 2 of rotor, and rotor shaft 17 connects as one with impeller shaft 13.Dividing plate 14 is divided into air cavity and water cavity two-part with the pump housing, and lower bearing 5 is tightly connected with dividing plate 14, and upper bearing (metal) 1 is tightly connected with housing 7 upper-end surfaces.Blade 15 vertically distributes on eccentric rotor 16 circumference, and the number of blade is generally odd number, for example 5,7,9.Suction port 4 is connected with tunnel compressed air ajutage (meaning not shown in the figures), for the ease of the control air output, manual air valve switch 3 is installed on suction port.Water intake 8 is positioned at the housing lower end surface, be up-small and down-big frustoconic shape, there is the spike 10 of protrusion the bottom, make water intake have the effect of bearing concurrently, water intake is located at down the bottom, is convenient to draining and tunnel ponding is drained, 11 filter openings of opening for the water intake periphery among the figure, 9 for covering the filter screen of water intake, stops the silt foreign material to enter in the pump.
The utility model is a power with pressurized air, enters the pump housing by suction port, promotes blade and drives rotor rotation, rotate by rotor shaft, impeller shaft impeller, in the water cavity of pump, produce negative pressure, make ponding enter the pump housing, discharge by water outlet (or through waste pipe) by water intake.This pneumatic pump is not afraid of humidity, safe and reliable, just energy self-priming of water is arranged, do not stay ponding, short time water is drained back idle running wound water pump, overcome the tunnel and used electric water pump easily to burn shortcomings such as motor, chance gas explosive, and the air that uses the back to be discharged by the air outlet still can play ventilation, dust discharge effect.Be particularly suitable for tunnel drainings such as colliery, tunnel, underground fortification.
The heavy 18kg of pump among the embodiment, water intake diameter 46mm, water outlet diameter 36mm, during pressurized air air pressure 0.5Mpa, 13 cubic metres/h of flow, lift 8m, pressurized air air pressure 0.4Mpa gets final product work, is equivalent to an air pressure gun with air quantity.
Claims (4)
1, the tunnel wind-driven water pump, form and comprise housing, water intake, water outlet, impeller, impeller shaft, it is characterized in that also comprising dividing plate, rotor, rotor shaft, upper bearing (metal), lower bearing, the blade that connects rotor, suction port, the air outlet, dividing plate is divided into air cavity and water cavity two-part with the pump housing, rotor is positioned at air cavity, rotor shaft and impeller shaft connect as one, upper bearing (metal) and housing upper-end surface are tightly connected, lower bearing and dividing plate are tightly connected, the blade of rotor vertically distributes on rotor circumference, suction port, the air outlet is positioned on the housing at air cavity place, water intake, water outlet is positioned on the housing of water cavity place.
