Abstract

The invention relates to a zero-electricity consumption water current pressurizer, which comprises a water pipe and a gear box, wherein the two ends of the water pipe are respectively provided with a water pipe inlet and a water pipe outlet. A pipe under the water pipe inlet and a pipe front the water pipe outlet are respectively embedded with an impeller shell, two impeller shells are internally and respectively provided with an inlet impeller and an outlet impeller, the inlet impeller is coaxially provided with a large bevel wheel by a connecting shaft, the outlet impeller is coaxially provided with a small bevel wheel by the connecting shaft, and the large bevel wheel is engaged with the small bevel wheel. The tooth number ratio of the large bevel wheel to the small bevel wheel is 2:1; and the impeller at the water pipe inlet can absorb power of water source, the power is transmitted to the outlet impeller by the gears, and the rotate speed of the outlet impeller is higher than that of the inlet impeller as the gear set has a certain rotate speed ratio to accelerate the water current, so that the water current has higher power to achieve the aims of increasing water head and improving water pressure. Particularly, an overflow pipe is arranged to use some part of water which is without power.

Description

Zero-electricity consumption water current pressurizer

Technical field

The present invention relates to a kind of waterflow boosting device, especially a kind of suction booster that need not to consume user's electric energy.

Background technique

No matter still be that fluid pressurized equipment all is absolutely necessary at industrial field in life.Hydraulics of today is very flourishing, but must use electric energy bar none, and its energy consumption also is quite huge.

As Chinese utility model patent, the patent No. is 02256368, discloses a kind of automatic loading water energy-saving pump, and it is the automatic loading water energy-saving pump that a kind of agricultural irrigation is used.This pump has the pump housing, intake pipe, intake pipe is horizontal by several angle, the artificial drop that forms, and be communicated with the pump housing, Water gate valve, air chamber, sidepiece are respectively equipped with outlet pipe and air entraining pipe on being provided with in the pump housing, and air entraining pipe is communicated with outlet pipe, and the bottom of the pump housing is provided with water-blocking groove, groove top is provided with fixed dam, and bottom land is connected with movable block water plate.This pump is to reach automatically by the current moment of inertia to draw water, pump up water, and can make full use of the waterpower irrigation that natural water source carries out the farmland, and need not the function that power can be realized automatic loading water.But this pump can not improve the pressure of liquid obviously, can't reach the purpose of supercharging.

Summary of the invention

The present invention will provide a kind of Zero-electricity consumption water current pressurizer, the chronotropic action that this pressurized machine is connected and is produced by the gear that utilizes the different numbers of teeth, in the liquid of fraction, make the liquid of a part can have bigger delivery pressure the concentration of energy of most of liquid.Be applicable to the residential building of layering or zone water supply etc.

For achieving the above object, technological scheme of the present invention is: a kind of Zero-electricity consumption water current pressurizer, comprise water pipe, the water pipe two ends are respectively equipped with pipe inlet and pipe outlet, gear-box, be characterized in: inlay an impeller housing respectively on the pipe of on the pipe below the pipe inlet and pipe outlet front, be separately installed with inlet impeller and outlet impeller in two impeller housing, the inlet impeller is by the coaxial installation large helical gear of coupling shaft, the outlet impeller is by the coaxial installation bevel pinion of coupling shaft, and large helical gear and bevel pinion are connected with a joggle.

The gear ratio of large helical gear and bevel pinion is 2: 1; Be provided with spill pipe below the water pipe; The coupling shaft that connects large helical gear and bevel pinion in the gear-box by bearing fixing.

The invention has the beneficial effects as follows: the present invention is 2: 1 helical gear by installation impeller and a pair of gear ratio in the entery and delivery port of water pipe.Two impellers play opposite effect respectively.Wherein the impeller of ingress is embedded in by the water inlet water pipe of opening, and when current from top to bottom the time, current just can drive this wheel rotation.Bevel pinion impeller rotation this moment, again by the interlock transmission to large helical gear, thereby make wheel rotation, give water in the water pipe with energy.Because the relation of gear ratio, the impeller in outlet port can have higher rotating speed than the impeller of ingress, then has the current of same line speed also can obtain bigger kinetic energy with impeller, thereby reaches the purpose that improves head, supercharging.Because all power comes from current itself fully, therefore has obvious energy-saving effect.In addition, the present invention has given another part water with the energy of a part of water, so certainly will some water can lose original energy and gather, so below a spill pipe is arranged on the water pipe of water, the water that water conservancy diversion accumulates is also supplied with the user who gives bottom with it.

Embodiment

The invention will be further described below in conjunction with accompanying drawing and embodiment.

As shown in Figure 1 to Figure 3, the present invention mainly comprises pipe inlet 1, coupling shaft 2, inlet impeller 3, large helical gear 4, spill pipe 5, impeller housing 6, bevel pinion 7, outlet impeller 8, pipe outlet 9, gear-box 10.

Inlay an impeller housing 6 respectively on the pipe below the pipe inlet 1 and on the pipe of pipe outlet 9 fronts, be separately installed with inlet impeller 3 and outlet impeller 8 in two impeller housing 6, inlet impeller 3 is by the coaxial installation large helical gear 4 of coupling shaft, outlet impeller 8 is by the coaxial installation bevel pinion 7 of coupling shaft, and large helical gear 4 is connected with a joggle with bevel pinion 7.

Large helical gear 4 is 2: 1 with the gear ratio of bevel pinion 7; Be provided with spill pipe 5 below the water pipe; The coupling shaft that connects large helical gear 4 and bevel pinion 7 in the gear-box 10 by bearing fixing.

Inlet impeller 3 has played the effect that absorbs the kinetic energy of source current, gives bevel pinion 7 with it by large helical gear 4 transmissions.And the rotating speed of bevel pinion 7 doubles large helical gear 4, so the drive by coupling shaft 2 is the rotating speeds that outlet impeller 8 produces much larger than ingress impeller 3 again, so given the bigger kinetic energy of water at pipe outlet 9 places, has promptly increased head.When the water at pipe outlet 9 places obtained kinetic energy, the water of some can lose kinetic energy, and this part loses the water of kinetic energy just via spill pipe 5 discharge systems, supplied with the user who gives lower floor.Because the rotation of impeller can produce centrifugal force, make that The water splash in all directions, therefore in order to prevent that this phenomenon from having added an impeller housing 6 especially outside it.In addition, gear-box 10 is arranged, see other structures for convenience clearly, just with its blanking at two large and small

helical gear

4,7 places.The effect of gear-box 10 is rigid bearings and prevents that machine oil from oozing out the infiltration with water.
