Abstract

The utility model provides a hydraulic or steam engine. The engine is characterized in that a nozzle can rotate around an axial line shared with a rotary wheel, when the nozzle ejects liquid or vapor, the rotary wheel is pushed to rotate, and the nozzle is pushed to rotate in an opposite direction due to the reaction of liquid or vapor. Since mechanical energy is converted via two stages, the whole engine has high efficiency, and particularly mechanical energy whose rotary direction is different can be simultaneously output to drive the stator and the rotor of an engine for conveniently converting into electric energy.

Description

Engine

The utility model belongs to the nozzle of fluid power or steam engine, particularly motor.

Before the utility model, water turbine (fluid motor) and the existing very long history of steamer, in this very long historical process, they almost obtain perfect improvement, and water turbine to water turbine, is divided into impulse turbine from last notes formula water wheels, waterpower plunger type machine again, reaction turbine, can be divided into axial flow again, non-axial flow hydraulic turbine, bucket leaf formula, blade type or the like; Steamer has the single-stage impulse, reactionary style, and the simple turbine of two-row velocity-stage, and multistage, the steam turbine that mixes or the like.But the improvement of being done substantially all is the improvement to the shape of active wheel, blade, and all is to utilize the impulse action principle of liquid and steam that liquid or steam energy (motion, gesture, pressure, heat) are converted into mechanical energy mainly.And the technological standpoint that forms the habit, the structure of less consideration nozzle, particularly nozzle integral body and how to make full use of reaction principle and be converted to mechanical energy.

The purpose of this utility model is technical at present comparatively perfect water wheels (fluid motor) machine, steamer, be on various runners and the blade, its nozzle is transformed, make steaming water turbine or steamer not only utilize the impulse action principle, and utilize reaction principle simultaneously, with the transformation of energy of liquid or steam is mechanical energy, with the efficient of raising engine power conversion, and widens the thinking of engine design and the scope of use.

At present all fluid motors, the nozzle of steamer are all fixed, and utilize the liquid or the gas that spray from nozzle, promote blade on the runner by the principle of impulse action, rotate thereby promote runner, and outside output mechanical energy reaches the purpose of switching energy.The utility model then is on this basis, the nozzle body that nozzle and connected feed liquor (vapour) pipeline (or air chamber) are constituted, being designed to can be around the rotational identical with runner, the blade that nozzle is aimed on the runner is made circular movement, be that blade on nozzle and the runner remains best relative position in circular movement, and rotating shaft of nozzle body and runner shaft be on same axis, but be separated from each other (independence).Like this, when nozzle ejection liquid or gas, according to principle of momentum conservation (or reaction principle), nozzle is made circular movement with the direction opposite with liquid or gas emission direction, and drive nozzle body rotates, thereby output rotary machine energy, meanwhile, when nozzle ejection liquid or gas, blade on the runner that nozzle is aimed at, also because the effect (or effect of gravity) of impulsion, drive runner and press liquid or the rotation of gas emission direction, so just export two rotary machine energy that direction is opposite respectively, utilized impulse action and reverse action usefulness simultaneously, divide secondary to be converted to mechanical energy the energy of liquid or gas by nozzle body and runner, create conditions for improving the complete machine conversion efficiency, the rotating ratio of appropriate design nozzle and runner, the speed of ejection liquid, and nozzle, the nozzle body, runner, technical parameters such as blade will improve the efficient of complete machine transformation of energy.The nozzle body can be designed as one or some and constitutes or be disc by the center of circle and at the pipe that circle centre position links.Nozzle is generally by a pair of or somely be distributed on the same circumference that the nozzle body rotates and towards same sense of rotation being symmetrical in the center of circle.The paired symmetrical center of circle of nozzle is distributed on the nozzle body, helps preventing that unidirectional force from acting in the nozzle rotating shaft, raises the efficiency, and every pair of nozzle turns over 180 degree relatively simultaneously, prevents that wherein one jet holds together disorderly another strand jet work, when particularly operation material is liquid.The motion circumference of nozzle can be on the periphery of runner, and nozzle is aimed at the blade on the runner from outside to inside, the runner of Pei Heing with it, and water turbine (fluid motor) is generally radial inflow or axial axis streaming runner, and steamer is generally impact type runner (Fig. 1).The motion circumference of nozzle also can be on the interior week of runner, and nozzle is aimed at the blade on the runner from inside to outside, the runner of Pei Heing with it, and water turbine is generally centrifugal runner, and steamer is impact type runner (Fig. 2).The motion circumference of nozzle also can be on a side of runner, the blade on the nozzle lateral alignment runner, and this form is used for steamer more, the runner of Pei Heing is the reactionary style runner with it, general normal is the multistage reactionary style steamer of tape speed level, certainly, also can be used for fluid motor (Fig. 3).The nozzle axle separates with rotating shaft, can be made of two sections axles that separate and bearing separately, considers combining closely of nozzle and runner upper blade, and the fitted bearing between the most handy sleeve and the sleeve constitutes.

The utility model is for fluid motor, because highly pressurised liquid has only through the nozzle ejection, therefore there is not liquid to flow to the situation of low pressure area by the zone of high pressure active wheel of uniting, liquid by the nozzle ejection also promotes the runner rotation then, in fact divide the secondary conversioning mechanical energy, thereby improve the efficient of transformation of energy.For steamer, the nozzle through rotating also equals to add one-level, improves the efficient of complete machine, simultaneously, because steamer is bigger through rotating the nozzle heat drop, at different levelsly after therefore can use the relatively poor made of temperature classification, thereby reduce cost.And the utility model is used for driving the stator and the rotor of generator owing to export the mechanical energy of two direction of rotation simultaneously, can improve the speed of relative cutting magnetic line, is converted to electric energy very easily.

A description of drawings and an embodiment of the present utility model.Fig. 1 is in the schematic representation of rotor periphery with nozzle motion circle designs; Fig. 2 is with nozzle motion circle designs schematic representation on week in runner; Fig. 3 designs nozzle in the schematic representation of runner one side; Fig. 4 is an an embodiment's of the present utility model schematic representation, among the figure: 1, be the nozzle body, 2, be nozzle, 3, be the nozzle axle, 4, be runner, 5, blade, 6, runner shaft, 7, water intake, 8, the cover axle bearing.
