Description

异型腔原动机技术领域 Hetero-cavity prime mover

本发明涉及异型腔原动机，属流体机械和能源技术领域。 The invention relates to a heterogeneous cavity prime mover, and belongs to the technical field of fluid machinery and energy.

背景技术 Background technique

原动机是将水能、风能、热能、电能等自然能量或人造能量转化为机械原动力的机械装置，可以按照所使用能源类型的区别划分成不同的种类，例如水轮机、风力机、燃气轮机、蒸汽机、电动机、液压马达等。其中水轮机和液压马达属液力原动机，前者能够将液体（水）的动能转化为输出轴的旋转驱动力，后者则将液体的压力能转化为输出轴的旋转驱动力。原动机作为现代生产和生活的主要动力来源，其技术水平，不仅直接影响能源利用率和其它资源消耗，而且与保障安全生产和降低产出成本密切相关。因此，现代经济和产业技术的发展对原动机提出了更高的要求，包括能量效率、功率范围、转动速度、运转稳定性、工作可靠性、流量可调节性、结构复杂性、强度、重量、体积、安装条件、可维护性、制造工艺性等诸多方面。 The prime mover is a mechanical device that converts natural or artificial energy such as water, wind, heat, and electric energy into mechanical motive force. It can be divided into different types according to the type of energy used, such as turbines, wind turbines, gas turbines, steam engines, Electric motor, hydraulic motor, etc. Among them, the hydraulic turbine and the hydraulic motor are hydraulic prime movers. The former can convert the kinetic energy of the liquid (water) into the rotational driving force of the output shaft, and the latter converts the pressure energy of the liquid into the rotational driving force of the output shaft. As the main source of power for modern production and life, prime mover's technical level not only directly affects energy utilization and other resource consumption, but also is closely related to ensuring safe production and reducing output costs. Therefore, the development of modern economy and industrial technology puts higher demands on the prime mover, including energy efficiency, power range, rotational speed, operational stability, operational reliability, flow adjustability, structural complexity, strength, weight, Volume, installation conditions, maintainability, manufacturing processability and many other aspects.

现有每一个主要类型的原动机，都有经过长期研究和使用形成的一些基本结构形式。例如在水轮机方面，有反击式水轮机和冲击式水轮机两大类，其中反击式水轮机又分为轴流式、贯流式、混流式及斜流式等结构形式。又如液压马达有齿轮式、叶片式、径向柱塞式和轴向柱塞式几种基本结构类型。但是，仅凭改进和完善现有形式的原动机，并不能完全适应新的技术和经济性需求。这是由于原动机的一些主要技术性能指标之间存在着相互制约，而在原动机的原有结构形式下，这些矛盾（与原动机的特定构造和工作特性有关）难以得到有效解决。水轮机的能量转换效率、抗空化能力、比转速三项性能，就是这种情况。液压马达的低速稳定性、转矩脉动、容积效率、结构复杂度之间也有同样的问题。 Each of the main types of prime movers currently has some basic structural forms that have been formed through long-term research and use. For example, in the aspect of hydraulic turbines, there are two types of counter-turbine turbines and impact turbines, and the counter-turbine turbines are further divided into axial flow type, cross flow type, mixed flow type and diagonal flow type. Another example is the hydraulic motor with several basic structural types: gear type, vane type, radial piston type and axial plunger type. However, simply improving and refining the existing form of prime mover does not fully adapt to new technical and economic needs. This is because there are mutual constraints between some of the main technical performance indicators of the prime mover, and under the original structural form of the prime mover, these contradictions (specific with the prime mover) The structure is related to the working characteristics) It is difficult to solve it effectively. This is the case for the turbine's energy conversion efficiency, cavitation resistance, and specific speed. The same problem exists between the low speed stability of the hydraulic motor, torque ripple, volumetric efficiency, and structural complexity.

因此，克服现有原动机存在的缺陷，需要寻求新的结构形式和工作原理。此外，现有的原动机一般都不能计量流量，而计算机网络技术的广泛应用和生产管理科学化的发展趋势，必然会要求原动机具备流量计量功能。发明内容 Therefore, to overcome the shortcomings of existing prime movers, it is necessary to seek new structural forms and working principles. In addition, the existing prime movers generally cannot measure the flow rate, and the widespread application of computer network technology and the scientific development trend of production management will inevitably require the prime mover to have a flow metering function.

Assembly procedure of the device:

一、将两块槽形滑板 33对插到第一导向槽 20内，对插前，先在两块槽形滑板 33之间装入第一弹性元件 27。两块槽形滑板 33和第一弹性元件 27组装在一起，构成第一组合滑板 8。然后，将两块 T形滑板 34对插到第二导向槽 21内。对插前，先在两块之间装入第二弹性元件 29。两块 T形滑板 34和第二弹性元件 29组装在一起，构成第二组合滑板 9。第一组合滑板 8和第二组合滑板 9与转子本体 6的组合体，构成转子。 1. Insert the two grooved slide plates 33 into the first guide groove 20, and insert the first elastic member 27 between the two grooved slide plates 33 before the insertion. The two grooved slide plates 33 and the first elastic member 27 are assembled to constitute the first combined slide plate 8. Then, the two T-shaped slide plates 34 are inserted into the second guide grooves 21. Before the insertion, the second elastic member 29 is first inserted between the two blocks. Two T-shaped slides 34 and a second elastic member 29 are assembled to form a second combined slide 9. The combination of the first combined slide plate 8 and the second combined slide plate 9 and the rotor body 6 constitutes a rotor.

异型腔原动机工作时，进口 2和出口 3之间流体的压力差驱动转子转动，传动轴 9将动力向外输出。 When the heterogeneous prime mover is working, the pressure difference between the fluid between the inlet 2 and the outlet 3 drives the rotor to rotate, and the drive shaft 9 outputs the power to the outside.

当进口 2 —侧的流体压力高于出口 3 —侧的流体压力时，转子按 A→B→C→D方向转动，异型面内腔的第二过渡弧面 BC推动第一组合滑板 8和第二组组合滑板 9交叉滑动。当出口 3—侧的流体压力高于进口 2—侧的流体压力时，转子按 B→A→D→C方向转动，异型面内腔的第一过渡弧面 DA推动第一组合滑板 8和第二组组合滑板 9交叉滑动。不论转子按哪一方向转动，每转一周，在密封腔内的 AB空间连续形成 4个标准容积。，使等量流体流过密封腔。永磁元件 7向密封腔外发送转子转动周数 N的信号。本装置的工作原理： When the fluid pressure on the side of the inlet 2 is higher than the fluid pressure on the side of the outlet 3, the rotor rotates in the direction of A→B→C→D, and the second transitional arc surface BC of the inner cavity of the profiled surface pushes the first combined slide 8 and the first The two sets of combined slides 9 are cross-sliding. When the fluid pressure on the outlet 3 side is higher than the fluid pressure on the inlet 2 side, the rotor rotates in the direction of B→A→D→C, and the first transitional arc surface DA of the profiled cavity pushes the first combination slide 8 and the first The two sets of combined slides 9 are cross-sliding. Regardless of which direction the rotor rotates, each time one revolution, four standard volumes are continuously formed in the AB space in the sealed chamber. , allowing an equal amount of fluid to flow through the sealed chamber. The permanent magnet element 7 transmits a signal of the number N of revolutions of the rotor to the outside of the sealed chamber. The working principle of this device:

一、能量转换：由图 1 可以看到，在转子的任何旋转角度下，都会有一块槽形滑板 33或 T形滑板 34处在异型面内腔的 AB区域内，并伸出转子本体 6与 1/4圆弧面 AB接触。设进口 2—侧的流体压力为 g_in，出口 3 一侧的流体压力为。_ut，则压力差 g_m- 。_ut通过 AB区域内的槽形滑板 33或 T形滑板 34对转子的轴线 ( 形成转动力矩 M₀, 1. Energy Conversion: As can be seen from Figure 1, at any angle of rotation of the rotor, there will be a slotted slide 33 or T-shaped slide 34 in the AB area of the profiled cavity and extending out of the rotor body 6 1/4 arc surface AB contact. Let the fluid pressure on the side of the inlet 2 be g _in and the fluid pressure on the side of the outlet 3 be. _Ut , then the pressure difference g _m - . _Ut passes the slotted slide 33 or the T-shaped slide 34 in the AB region to the axis of the rotor (forming a rotational moment M ₀ ,

_M H(q_m - q_o (R - r)(R + r) _{( 3 )} _M H(q _m - q _o (R - r)(R + r) _{( 3 )}

0 2 ° 只要 M。大于转子受到的阻抗力偶，便会驱动转子转动（槽形滑板 33和 T 形滑板 34交替进入 AB区域），由传动轴 14向外输出旋转动力。 0 2 ° as long as M. More than the resistance couple received by the rotor, the rotor is driven to rotate (the slotted slide 33 and the T-shaped slide 34 alternately enter the AB area), and the rotary shaft is outputted outward by the drive shaft 14.

二、流量计量：因为第一组合滑板 8与第二组合滑板 9是垂直交叉的，当其中一组组合滑板（例如第一组合滑板 8 )处在 AC位置时，另一组组合滑板（第二组合滑板 9) 则刚好处于 BD位置，如图 1 (a)所示。此时，密封腔内由两组组合滑板与异型柱面内腔的四分之一圆弧面 AB 所围成的空间区域构成一个标准容积 _Q。转子每转过一周，有 4个标准容积 _Q形成，同时有 4个标准容积（4 _Q) 的流体由出口 3排出。构成标准容积的 AB空间区域是异型腔原动机的计量空间，也称为计量室。异型腔原动机工作过程中通过腔体的流体体积流量，按以下公式计算： Second, the flow metering: because the first combination slide 8 and the second combined slide 9 are perpendicularly intersected, when one set of combined slides (for example, the first combined slide 8) is in the AC position, another set of combined slides (second The combination slide 9) is just in the BD position, as shown in Figure 1 (a). At this time, a space area surrounded by two sets of combined slides and a quarter arc surface AB of the shaped cylindrical cavity in the sealed cavity constitutes a standard volume _Q. Four revolutions of _{Q are} formed per revolution of the rotor, while four standard volumes (4 _Q ) of fluid are discharged from outlet 3. The AB space region constituting the standard volume is the metering space of the heterogeneous cavity prime mover, also referred to as the metering chamber. The fluid volume flow through the cavity during the operation of the heterogeneous prime mover is calculated according to the following formula:

V= NV_Q (4)。 V = NV _Q (4).

三、组合滑板的运动控制：考査异型腔原动机工作过程中组合滑板的运动，设第一组合滑板 8的初始位置为 AC, 第二组合滑板 9的初始位置为 BD，参看图 1 (a)。此时，第一组合滑板 8的左端（上端）位于 1/4圆弧面 AB与第一过渡弧面 DA的交界处 A，它的右端（下端）位于 1/4圆弧面 CD 与第二过渡弧面 BC的交界处 C; 第二组合滑板 9的右端（上端）位于 1/4 圆弧面 AB与第二过渡弧面 BC的交界处 B，它的左端（下端）位于 1/4圆弧面 CD与第一过渡弧面 DA的交界处 D。当转子按 A→B→C→D方向转动时，两块组合滑板随之转动。 Third, the motion control of the combined skateboard: To examine the movement of the combined skateboard during the working process of the abnormal cavity prime mover, the initial position of the first combined slide 8 is AC, and the initial position of the second combined slide 9 is BD, see Fig. 1 (a) . At this time, the left end (upper end) of the first combination slide plate 8 is located at the boundary A of the 1/4 arc surface AB and the first transition arc surface DA, and the right end (lower end) thereof is located at the 1/4 arc surface CD The boundary C with the second transitional arc surface BC; the right end (upper end) of the second combined slide plate 9 is located at the boundary B of the 1/4 arc surface AB and the second transition arc surface BC, and its left end (lower end) is located at 1 /4 The intersection of the circular arc surface CD and the first transitional arc surface DA. When the rotor rotates in the direction of A→B→C→D, the two combined slides rotate accordingly.

第一组合滑板 8在由 AC位置转到 BD位置，即旋转 90°通过计量室的过程中，其上下两端分别与内腔的 1/4圆弧面 AB和 1/4圆弧面 CD保持弹性接触，因此第一组合滑板 8的长度不变并相对于转子本体 6保持静止。同时，第二组合滑板 9的右端沿第二过渡弧面 BC由 B向 C转动，其左端则沿第一过渡弧面 DA由 D向 A转动。随着第二组合滑板 9的右端沿第二过渡弧面 BC由 B转到 C，第二过渡弧面 B推动第二组合滑板 9在转子本体 6的第二导向槽 21内滑移，同时第二组合滑板 9的左端沿第一过渡弧面 DA滑动，直至到达端点 A，此时第二组合滑板 9的右端到达第二过渡弧面 BC的端点 C。当第二组合滑板 9转到 AC位置而第一组合滑板 8转到 BD 位置时，两块组合滑板交换动作，重复前面 90°的旋转过程。以后，组合滑板的运动周期性地重复以上动作，参看图 1。 The first combined slide plate 8 is moved to the BD position from the AC position, that is, during the rotation through 90° through the metering chamber, the upper and lower ends thereof are respectively maintained with the 1/4 arc surface AB and the 1/4 arc surface CD of the inner cavity. The elastic contact, so that the length of the first combined slide 8 does not change and remains stationary with respect to the rotor body 6. At the same time, the right end of the second combination slide 9 is rotated by B to C along the second transitional arc surface BC, and the left end thereof is rotated by D to A along the first transitional arc surface DA. As the right end of the second combined slide 9 is turned from B to C along the second transitional arc surface BC, the second transitional curved surface B pushes the second combined slide 9 to slide in the second guide groove 21 of the rotor body 6, and at the same time The left end of the second combination slide 9 slides along the first transition arc surface DA until reaching the end point A, at which time the right end of the second combination slide 9 reaches the end point C of the second transition arc surface BC. When the second combination slide 9 is turned to the AC position and the first combined slide 8 is turned to the BD position, the two combined slides exchange actions, repeating the previous 90° rotation process. Later, the motion of the combined slider periodically repeats the above actions, see Figure 1.

四、转子内部的导流机构：在第二组合滑板 9由 AC位置转到 BD位置而第一组合滑板 8由 BD位置转到 AC位置并在第一导向槽 20内向左滑动的过程中，第二组合滑板 9下部的 T形滑板 34上的第二导流孔 19处于与转子本体上的中间导流孔 17同轴的位置，将第一组合滑板 8的两块槽形滑板 34之间的左右两个空腔部分连通。由于第一组合滑板 9向左滑动，左侧空腔的体积连续增大形成负压而右侧空腔的体积连续减小形成正压，因此右侧空腔内的流体通过第二导流孔 19和中间导流孔 17流入左侧空腔，参看图 2、图 4、图 5、图 6。第二导流孔 19和中间导流孔 17由此起到了释放转子内部空腔压力从而保证转子能够顺利转动的作用，同时，第二导流孔 19和中间导流孔 17导流孔对组合滑板的滑动乃至转子的转动也产生一定的阻尼作用。 4. The flow guiding mechanism inside the rotor: in the process that the second combined sliding plate 9 is turned from the AC position to the BD position and the first combined sliding plate 8 is turned from the BD position to the AC position and slides to the left in the first guiding groove 20, The second air guiding hole 19 on the lower T-shaped sliding plate 34 of the second combined sliding plate 9 is at a position coaxial with the intermediate guiding hole 17 on the rotor body, and between the two grooved sliding plates 34 of the first combined sliding plate 8. The left and right cavity portions are in communication. Since the first combined slide 9 slides to the left, the volume of the left cavity continuously increases to form a negative pressure and the volume of the right cavity continuously decreases to form a positive pressure, so the fluid in the right cavity passes through the second guide hole. 19 and the intermediate flow guiding hole 17 flow into the left cavity, the reference See Figure 2, Figure 4, Figure 5, Figure 6. The second air guiding hole 19 and the intermediate air guiding hole 17 thus play the role of releasing the internal cavity pressure of the rotor to ensure the smooth rotation of the rotor, and at the same time, the second guiding hole 19 and the intermediate guiding hole 17 are combined with the guiding hole pair. The sliding of the sliding plate and even the rotation of the rotor also exert a certain damping effect.

类似地，在第一组合滑板 8由 AC位置转到 BD位置而第二组合滑板 9 由 BD位置转到 AC位置并在第二导向槽 21内向左滑动的过程中，第一组合滑板 8下部的槽形滑板 33上的第一导流孔 18处于与转子本体上的侧翼导流孔 16同轴的位置，将第二组合滑板 9的两块 T形滑板 34之间的左右两个空腔部分连通。由于右侧空腔的体积连续增大而左侧空腔的体积连续减小，因此右侧空腔内流体通过第一导流孔 18和侧翼导流孔 16流入左侧空腔。 Similarly, in the process of the first combination slide 8 being turned from the AC position to the BD position and the second combined slide 9 being turned from the BD position to the AC position and sliding to the left in the second guide groove 21, the lower portion of the first combination slide 8 The first flow guiding hole 18 on the grooved slide plate 33 is at a position coaxial with the side wing flow guiding hole 16 on the rotor body, and the left and right cavity portions between the two T-shaped sliding plates 34 of the second combined sliding plate 9 Connected. Since the volume of the right side cavity continuously increases and the volume of the left side cavity continuously decreases, the fluid in the right side cavity flows into the left side cavity through the first flow guiding hole 18 and the side wing guiding hole 16.

五、对流体内泄的控制：当密封腔中转子与密封腔内壁以及转子自身各运动件之间的所有滑动配合的间隙都足够小时，转子在密封腔内即形成一个动密封机构，使流体不能以间隙渗漏的方式由进口 2流到出口 3。 V. Control of fluid leakage: When the clearance between the rotor and the inner wall of the sealing chamber and the moving parts of the rotor itself is small enough, the rotor forms a dynamic sealing mechanism in the sealing cavity, so that the fluid cannot Flow from the inlet 2 to the outlet 3 in a leaky manner.

六、转子防卡死：当流体中含有的固体颗粒进入第一组合滑板 8或第二组合滑板 9的端部区域而产生卡滞作用时，弹性元件 27和弹性元件 29可以发生压缩变形，使组合滑板的长度减小，因而转子能够继续转动，不被卡死。 6. Anti-seize of the rotor: When the solid particles contained in the fluid enter the end region of the first combined slide plate 8 or the second combined slide plate 9 to cause a jam, the elastic member 27 and the elastic member 29 can be compressed and deformed. The length of the combination slide is reduced so that the rotor can continue to rotate without being stuck.
