Description
技术领域 Technical field
本发明涉及超音速喷射推进马达技术领域，具体涉及到一种喷射式旋转马达。 The present invention relates to the field of supersonic jet propulsion motors, and in particular to a jet type rotary motor.
背景技术 Background technique
现有的以高压流体做动力的机械，如：气动马达、蒸汽机、汽轮机、水轮机、汽油机、柴油机、燃气轮机、航空涡轮发动机等，都是以高压流体冲击叶片、涡轮或者是活塞的形式来推动马达旋转的。根据力学常识，这个力俗称为'冲动力'。目前市面上的机械基本上都是利用冲动力来作功的（火箭除外）。
Existing high-pressure fluid-powered machines, such as air motors, steam engines, steam turbines, water turbines, gasoline engines, diesel engines, gas turbines, and aviation turbine engines, all push the motor in the form of high-pressure fluid impinging blades, turbines, or pistons. Rotating. According to the common sense of mechanics, this force is called 'rushing power'. At present, the machinery on the market basically uses the impulse power to do work (except for the rocket).
以冲动力来作功的机械，理论上讲，其功率转换是达不到 25%
的，以汽轮机为例说明如下：汽轮机等透平机械主要利用高速气流冲击叶片，较多地依赖叶栅进出气流动量变化获得推力，一定气流速度条件下，叶片推力与转速相关。气流和叶片的相对速度差越大，所获得的推力越大，速度差越小，所获得的推力也越小（成正比）。当叶片的线速度达到气流喷射速度时，速度差为零，则叶片所获得的推力是零，这时的功率输出也是零。具体计算方法如下：设：一定温度一定压力下的蒸汽，通过拉瓦尔喷管后产生超音速射流，我们用
Ue 来表示。当叶片不动时，气流和叶片的速度差最大，等于 Ue ，也就是转子转速为零时，叶片所承受的冲动力最大。但是因为转速为零，根据机械功率计算公式
:N=P.F.r/9550 来计算【 N: 功率、 P: 推力、 F: 力距 =D/2 、 r: 转速 =Ue/ （∏ D ） x60 、 D ：转子 (
包括叶片 )
的直径】，功率输出也是零。当叶片在推力下开始转动后，随着叶片线速度的增加，转速在增加，随着气流和叶片的速度差在减小，推力也在减小。当叶片的线速度达到 Ue/2
时，推力 P 也只剩下 P/2 了，而这时的功率输出却最大，即 N=0.5P*F*0.5r/9550=0.25P.F.r/9550. 如果转子线速度大于或小于
Ue/2
时，功率输出都会减少。又因冲动式气流和叶片不能达到方向一致的相切，冲动力输入的角度会产生力的分解，多级膨胀不可避免的会产生泄露等，所以，纯冲动式的汽轮机的功率转换是不会达到
25% 的。 In terms of power, the power conversion is theoretically less than 25%.
Taking the steam turbine as an example, the following is explained: Turbine and other turbomachines mainly use high-speed airflow to impinge the blade, and rely more on the change of the flow of the inlet and outlet of the cascade to obtain the thrust. Under certain airflow conditions, the blade thrust is related to the rotational speed. The greater the difference in relative velocity between the airflow and the blades, the greater the thrust obtained, the smaller the speed difference, and the smaller the thrust obtained (proportional). When the linear velocity of the blade reaches the air jet velocity, the speed difference is zero, and the thrust obtained by the blade is zero, and the power output at this time is also zero. The specific calculation method is as follows: Set: a certain temperature of steam under a certain pressure, through the Laval nozzle to produce a supersonic jet, we use
Ue to indicate. When the blade is not moving, the difference between the velocity of the airflow and the blade is the largest, equal to Ue, that is, when the rotor speed is zero, the blade is subjected to the largest impulse. But because the speed is zero, the formula is calculated according to the mechanical power.
:N=P.F.r/9550 to calculate [N: power, P: thrust, F: force distance = D/2, r: speed = Ue / (∏ D ) x60, D: rotor (
Including the blade)
Diameter], the power output is also zero. When the blade begins to rotate under the thrust, as the linear velocity of the blade increases, the rotational speed increases, and as the velocity difference between the airflow and the blade decreases, the thrust also decreases. When the blade's linear velocity reaches Ue/2
At the time, the thrust P is only P/2, and the power output at this time is the largest, that is, N=0.5P*F*0.5r/9550=0.25P.F.r/9550. If the rotor linear speed is greater or less than
Ue/2
When the power output is reduced. Because the impulsive airflow and the blade can not reach the same direction tangent, the angle of the impulse input will generate the force decomposition, and the multi-stage expansion will inevitably lead to leakage, etc. Therefore, the power conversion of the pure impulse turbine is not achieve
25%.
同理可证，所有以冲动式作功的机械，其功率转换都不会达到 25%
，更不要说超过了。目前市面上俗称汽油机的效率在 35% 左右，柴油机在 40% 左右，汽轮机在 30-42% 之间，有待科学进一步计算和验证。 By the same token, all machines that use impulsive work will not achieve 25% power conversion.
Not to mention more than that. At present, the efficiency of the gasoline engine is about 35%, the diesel engine is about 40%, and the steam turbine is between 30-42%, which needs further scientific calculation and verification.
自古以来，也不断的有人在研究以喷射反作用力来作功的机械，如：大约在公元一世纪时期，亚历山大里亚的希罗就发明了一种利用蒸汽的反作用力来作功的《汽转球》，这也是有记载的最早的蒸汽机
,
但是只是被人们当作是一种玩具而没有继续研究和开发。汽轮机业发展到今天，一直把这种技术当作古老的已经过时的技术来屏闭，致使这种以喷射式反作用力来作功的机械，在科班出身的专家、学者、博士眼里是不受欢迎的。近年来，也有人在试验利用反作用力来作功的旋转机械，如
1989 年 11 月 15 日申请的名为《旋转动力机械及系列发动机》，公告号为 CN1037192A 的专利； 2004 年 1 月 8 号申请的公告号为
US 2004/005214A1 的专利； 2007 年 10 月 16 号申请的名为《喷气式发动机》，专利号为 200710056207.0 的专利；以及
2008 年 8 月 11 号申请的名为《一种喷气式发动机》，专利号为 200810150584.5
的专利等等。令人遗憾的是，这些专利的发明，只是对用反作用力来作功提出了设想，至于利用这种方式来作功的效率大小以及是不是会节能？为什么会节能？怎样才能更节能？节能多少？如何计算都未做陈述。例如：在上述几例发明中，虽然都说明了压缩气体进行喷射会产生反作用力，却没有一例提及压缩气体喷射后继续膨胀加速以及能产生超音速效果的唯一的部件
-- 拉瓦尔喷管，也称收缩膨胀管。
Since ancient times, there have been people who are constantly studying the work of spurting reaction forces. For example, around the first century AD, Hero of Alexandria invented a steam that uses steam to react. Turn the ball, this is also the earliest recorded steam engine
,
But it was only treated as a toy and not continued to be researched and developed. The steam turbine industry has developed to this day, and this technology has been closed as an old and outdated technology, so that the machine that uses the jet reaction force to work is not in the eyes of experts, scholars, and doctors born in the class. popular. In recent years, some people have been experimenting with rotating machinery that uses reaction forces to work, such as
The application titled "Rotary Power Machinery and Series Engines", published on November 15, 1989, with the publication number CN1037192A; the announcement number of the application on January 8, 2004 is
Patent No. 2004/005214A1; a patent entitled "Jet Engine", patent No. 200710056207.0, filed on October 16, 2007;
The application for "A Jet Engine" on August 11, 2008, the patent number is 200810150584.5
Patents and so on. Regrettably, the inventions of these patents only provide ideas for using the reaction force to do work. As for the efficiency of using this method to work, is it energy saving? Why is it energy efficient? How can I be more energy efficient? How much energy is saved? No calculations have been made on how to calculate. For example, in the above-mentioned several inventions, although it is explained that the reaction of the compressed gas to generate a reaction force, there is no mention of the only component that continues to expand and accelerate after the injection of the compressed gas and can produce a supersonic effect.
-- Laval nozzle, also known as shrinkage expansion tube.
根据发射气体动力学的原理知道，要充分发挥《喷射式旋转马达》的效率，关键在于尽量提高其转速，因为超音速喷射推进技术的特点，是依赖拉瓦尔喷管将具有一定压力的气体，通过喷管内型截面的'收缩
-
扩张'膨胀加速成超音速气体射流，由反作用原理产生动推力，推动喷管向前运动。这种超音速气体射流产生的推力，仅依赖于拉瓦尔喷管进出口气体参数，而与喷管自身运动速度无关，且该气体射流利用效率随喷管运动速度的增加而增加，直至运动速度与气体射流速度一致时达到最大（理论上是
100
％）。要达到这样的目的，该设备的《高速旋转密封接头》就显得犹为重要。而目前市面上的《旋转密封接头》，因受技术材料材质方面的制约，橡胶制品的密封，最大线速度为
15m/s, 机械密封的最大线速度为 25m/s
。因《喷射式旋转马达》进气端的轴是中空的，轴和转子联接处还要打孔相通，考虑机械运行时的安全问题，轴的设计比一般机械轴的直径尺寸要大一些，这样，转速高加上直径尺寸大，导致目前市面上所有的旋转密封接头都不能用。而从以上几个专利的图中来看，说到密封时就是简单的说要高压密封或者说通过连接器进行连接，根本就没有显示高速旋转密封的关键性问题，这也是导致这个项目的机械到现在也不能问世的主要原因之一。
According to the principle of the dynamics of the emitted gas, it is known that to fully utilize the efficiency of the "jet rotary motor", the key is to increase the speed as much as possible, because the supersonic jet propulsion technology is characterized by relying on the Laval nozzle to have a certain pressure of the gas, 'shrinkage through the inner section of the nozzle
-
The expansion 'expansion accelerates into a supersonic gas jet, and the reaction thrust generates a dynamic thrust that pushes the nozzle forward. The thrust generated by this supersonic gas jet depends only on the inlet and outlet gas parameters of the Laval nozzle, and is independent of the speed of the nozzle itself, and the gas jet utilization efficiency increases as the nozzle speed increases until the speed of movement Maximizes when the gas jet velocity is the same (theoretically
100
%). To achieve this goal, the device's "high-speed rotary sealing joint" is still important. At present, the "rotating sealing joint" on the market is sealed by the material of the technical material, and the maximum line speed is
15m/s, the maximum linear speed of the mechanical seal is 25m/s
. Because the shaft of the intake end of the "jet rotary motor" is hollow, the shaft and the rotor joint are also perforated. Considering the safety problem during mechanical operation, the shaft design is larger than the diameter of the general mechanical shaft. The high speed and large diameter make it impossible to use all the rotary sealing joints on the market. From the diagrams of the above patents, when it comes to sealing, it is simply to say that high-pressure sealing or connection through a connector does not show the key problem of high-speed rotary sealing, which is also the machine that leads to this project. One of the main reasons why it has not been published until now.
《喷射式旋转马达》的另一个关键问题，是在同一平面上不能多喷嘴同时使用，如公告号为 US
2004/005214A1 的专利，从图中看到， 8
个喷嘴封闭在一个空腔里，前一个喷嘴喷出来的气体除了对喷嘴产生一个反作用力外，还对后一个喷嘴产生正向的推力，而且作用力和反作用力相等持平，所以这样结构的产品是不会产生转动的，我们在实际实验中已经经受过这样的失败。 Another key issue of the Jet Rotary Motor is that multiple nozzles cannot be used simultaneously on the same plane, such as the US number.
Patent of 2004/005214A1, as seen in the figure, 8
The nozzle is enclosed in a cavity. The gas sprayed from the previous nozzle generates a positive thrust to the latter nozzle in addition to a reaction force to the nozzle, and the force and the reaction force are equal and flat, so the product of such structure It does not produce rotation, and we have experienced such failure in actual experiments.
发明内容 Summary of the invention
本发明的目的，是提供一种喷射式旋转马达，特别是一种利用高压流体喷射时产生的超音速射流的反作用力为动力的喷射式旋转马达。它能有效解决以上的不足。
SUMMARY OF THE INVENTION An object of the present invention is to provide a jet type rotary motor, and more particularly to a jet type rotary motor which uses a reaction force of a supersonic jet generated when a high pressure fluid is injected. It can effectively solve the above deficiencies.
一种喷射式旋转马达，它包括高速旋转密封接头、一字水滴型转子、缓冲摩擦副、喷管装配口和拉瓦尔喷管。 A jet rotary motor comprising a high speed rotary seal joint, a water drop type rotor, a buffer friction pair, a nozzle assembly port and a Laval nozzle.
高速旋转密封接头内的机械密封，加装了N个缓冲摩擦副，这样，就使各摩擦副之间的线速度降低到原有线速度的1/（N+1），在不改变摩擦副材质的情况下，为高转速机械提供了安全有效的密封效果。
The mechanical seal in the high-speed rotary sealing joint is equipped with N buffer friction pairs, so that the linear speed between the friction pairs is reduced to 1/(N+1) of the original linear speed, without changing the friction pair material. In this case, it provides a safe and effective sealing effect for high-speed machines.
高速旋转密封接头可以按照迷宫式密封来设计，因其无摩擦，所以使用寿命长，不需要维修。 The high-speed rotary sealing joint can be designed according to the labyrinth seal. Because it has no friction, it has a long service life and no maintenance is required.
一字水滴型转子总体设计为一字水滴型，使转子的旋转阻力降到最低。 The word-shaped rotor is generally designed as a water drop type to minimize the rotational resistance of the rotor.
为了加大发动机的功率，可以在一字水滴型转子的两端各设置多个喷管装配口。 In order to increase the power of the engine, a plurality of nozzle mounting ports may be provided at both ends of the water drop type rotor.
喷管使用拉瓦尔喷管。 The nozzle uses a Laval nozzle.
一字水滴型转子的装配口和拉瓦尔喷管之间可以加装燃烧室，以适应可燃动力机械的使用。 A combustion chamber may be installed between the assembly port of the water drop type rotor and the Laval nozzle to accommodate the use of the flammable power machine.
可以使用不同的压力流体来代替不同的原动机如：喷气式旋转汽轮机、喷气式旋转汽油机、喷气式旋转柴油机、喷气式旋转燃气机、喷气式旋转航空发动机等。
Different pressure fluids can be used instead of different prime movers such as: jet rotary steam turbines, jet rotary gasoline engines, jet rotary diesel engines, jet rotary gas engines, jet rotary aviation engines, and the like.
为了解决高速旋转接头的难题，本发明创新了两种高速旋转接头，一种是迷宫式无磨擦高速旋转接头，因为无磨擦，所以不会产生磨损。一种是带有缓冲磨擦副的机械式密封高速旋转接头。为喷射式旋转马达能正常长时间工作打下了可靠的基础。
In order to solve the problem of high-speed rotary joints, the present invention has innovated two high-speed rotary joints, one of which is a labyrinth-type frictionless high-speed rotary joint, and since there is no friction, no wear is caused. One is a mechanically sealed high speed swivel joint with a cushioned friction pair. It provides a reliable basis for the long-term operation of the jet rotary motor.
为了减少转子的转动磨擦阻力和多喷管互相制约的阻力，本发明将转子设计成一字水滴型，把转子设计成一字型，只在两端使用喷管，有效的拉开了喷管之间的运行距离，不会产生前一个喷管喷出的气体射流对后一个喷管产生负向阻力，而且水滴流线型的转子外型使转子的旋转阻力降到最低。为了有效增加机械动力，可以在转子8的各端设计数个喷管装配口。
In order to reduce the rotational friction resistance of the rotor and the resistance of the multi-nozzle to each other, the present invention designs the rotor into a water drop type, and the rotor is designed in a single shape, and the nozzle is used only at both ends, effectively opening the nozzle between the nozzles. The running distance does not cause the gas jet from the previous nozzle to generate negative resistance to the latter nozzle, and the streamlined rotor shape minimizes the rotor's rotational resistance. In order to effectively increase the mechanical power, a plurality of nozzle fitting ports may be designed at each end of the rotor 8.
多喷管使用时，喷管的喷射方向要和转子的旋转方向有一个夹角，这样，除了可以产生旋转的力量外，还可以产生轴向的推力，用在行走的机械设备如航空发动机上还是可以的，只是在静止发动时有些浪费。
When the multi-nozzle is used, the injection direction of the nozzle should be at an angle with the rotation direction of the rotor, so that in addition to the force of rotation, an axial thrust can be generated for use on a walking mechanical device such as an aero engine. It's okay, it's just a waste when it's still.
本发明是将目前已经普遍应用在军事和航天火箭上的超音速喷射推进技术，应用到旋转机械领域的一种新的模式，将压缩气体的喷射、膨胀、加速过程在短短的拉瓦尔喷管内发挥到极限，并将这种超音速气体射流产生的动推力，全部作用在转子的最外缘，因此具有马力大、构造简单、维修方便、能量转换完全彻底（100%）的特性，可以有效节约能源、降低污染，是气动马达、蒸汽机、汽轮机、汽油机、柴油机、水轮机、燃气轮机、航空涡轮发动机的更新换代产品。

高压流体通过高速旋转密封接头1进入到主轴6的进气通道5，再通过转子8的气体通道7到达转子8的两端喷管装配口9，然后进入拉瓦尔喷管11，并通过拉瓦尔喷管11的内形收缩-膨胀管产生超音速射流，并对拉瓦尔喷管11产生反向的动推力，推动转子8旋转。转子8通过紧装在中心的主轴6一起旋转，并带动和主轴联结在一起的机械旋转做功。当拉瓦尔喷管11的线速度达到气体超音速射流时，功率转换达到最大（100%），和那些以冲动力作功的不可能达到25%效率的机械相比，其节能效果是显而易见的。
The high-pressure fluid enters the intake passage 5 of the main shaft 6 through the high-speed rotary sealing joint 1, and then reaches the nozzle assembly port 9 at both ends of the rotor 8 through the gas passage 7 of the rotor 8, and then enters the Laval nozzle 11 and passes through Laval. The inner contraction of the nozzle 11 - the expansion tube produces a supersonic jet and produces a reverse dynamic thrust to the Laval nozzle 11 to propel the rotor 8 to rotate. The rotor 8 is rotated together by a spindle 6 that is tightly mounted at the center, and drives mechanical rotation coupled with the spindle to perform work. When the linear velocity of the Laval nozzle 11 reaches the gas supersonic jet, the power conversion is maximized (100%), and the energy saving effect is obvious compared to those machines that do not achieve 25% efficiency with the power of the impulse.
