Description

一种多级球形压缩机A multi-stage spherical compressor

技术领域Technical Field

本发明涉及一种压缩机,特别是一种多级球形压缩机。The invention relates to a compressor, in particular to a multi-stage spherical compressor.

背景技术Background Art

球形压缩机是近年来新发明的一种全新结构的变容积机构,与活塞式压缩机、滚动转子式压缩机、涡旋式压缩机、螺杆式压缩机一样,可用于不同的应用领域,发挥着各自的优势。球形压缩机具有结构简单、运动件少、无进排气阀、密封可靠、可实现高压和易微型化设计等独特优势,特别是可在一个球形缸体内形成多个工作室,实现多级压缩,如专利号为200610104569.8、专利名称为“能实现多级压缩的球形压缩机”的中国专利所公开的多级球形压缩机,就是通过多级压缩逐级提升工质压力。The spherical compressor is a variable volume mechanism with a completely new structure invented in recent years. Like piston compressors, rolling rotor compressors, scroll compressors, and screw compressors, it can be used in different application fields and exerts its own advantages. The spherical compressor has the unique advantages of simple structure, few moving parts, no inlet and outlet valves, reliable sealing, high pressure and easy miniaturization design. In particular, multiple working rooms can be formed in a spherical cylinder to achieve multi-stage compression. For example, the multi-stage spherical compressor disclosed in the Chinese patent with patent number 200610104569.8 and patent name "spherical compressor capable of achieving multi-stage compression" increases the working fluid pressure step by step through multi-stage compression.

但由于球形压缩机的活塞旋转是通过具有偏心轴孔的主轴提供动力,当主轴旋转到转盘轴线与活塞轴线重合时,主轴作用在转盘上的合力与活塞和转盘的轴线垂直,主轴作用在转盘上的合力在此位置产生不了驱动活塞和转盘绕各自轴线转动的扭矩分量,无法使转盘和活塞旋转,这是此种结构球形压缩机机构运动的死点,转子通过死点位置需要通过机构的运动惯性才能正常运行;当运动状态为起始状态在死点位置或者恰好在该死点状态停止转动,则下次无法启动。为此,在该专利的技术方案中,在主轴与缸体相接触的转动面上分别设置永磁体,两永磁体相对的面极性相同,利用极性相同的排斥力,将主轴推开与死点位置成一定角度,防止在死点位置停机,但此种方法通用性差、可靠性差,对结构尺寸较大和润滑良好、摩擦力较小的结构可以通过运动惯性克服摩擦力使转子通过死点位置,但对于结构尺寸较小、润滑条件较差的结构,由于惯性小、摩擦力较大,在死点位置仍容易卡滞停机。However, since the rotation of the piston of the spherical compressor is powered by a main shaft with an eccentric shaft hole, when the main shaft rotates to the point where the axis of the turntable coincides with the axis of the piston, the resultant force of the main shaft on the turntable is perpendicular to the axis of the piston and the turntable. The resultant force of the main shaft on the turntable cannot generate a torque component at this position to drive the piston and the turntable to rotate around their respective axes, and the turntable and the piston cannot rotate. This is the dead point of the movement of the spherical compressor mechanism of this structure. The rotor needs to pass through the movement inertia of the mechanism to operate normally when passing through the dead point position; when the movement state is the starting state at the dead point position or stops rotating at the dead point state, it cannot be started next time. To this end, in the technical solution of this patent, permanent magnets are respectively arranged on the rotating surfaces where the main shaft contacts the cylinder body, and the opposite surfaces of the two permanent magnets have the same polarity. The repulsive force with the same polarity is used to push the main shaft away from the dead point position at a certain angle to prevent it from stopping at the dead point. However, this method has poor versatility and reliability. For structures with larger structural dimensions, good lubrication and smaller friction, the friction can be overcome by the inertia of movement to allow the rotor to pass the dead point position. However, for structures with smaller structural dimensions and poorer lubrication conditions, they are still prone to getting stuck and stopping at the dead point due to their small inertia and large friction.

在专利号为200610104569.8的专利技术后续应用开发中,又持续不断进行新的技术研发和创新设计,对球形压缩机过死点技术进行改进,如专利号分别为2013101006975名称为“一种用于球形压缩机的转盘旋转同步机构”、专利号为201410100390X名称为“一种球形压缩机转子防死机构”及专利号为2014105548366名称为“一种球形压缩机防卡死动力机构”的中国专利,其中,专利号为2013101006975的专利是通过在缸体内球面和转盘球面之间设置有弹性钢球和凹形滑道组成的转盘同步机构,通过弹性钢球瞬时转动扭矩使转子通过死点,但凹形滑道占用密封面导致密封性能降低,同时凹形滑道轨迹曲线复杂,加工困难;专利号为201410100390X的专利是通过在缸体内球面或者缸体座内球面上设置凹形滑道,在转子上设置导向销,通过导向销在死点位提供转子旋转扭矩,虽然解决了密封损失问题,但凹形滑道加工困难,增加了结构件,结构复杂。专利号为2014105548366的专利是在缸体座或者缸体上设置轨迹限位面,在转子上设置动力柄,通过动力柄与轨迹限位面配合产生转子旋转的扭矩,但轨迹限位面加工点复杂,也增加了零件数量,易损件多,结构复杂。In the subsequent application development of the patent technology with patent number 200610104569.8, new technology research and development and innovative design are continuously carried out to improve the over-dead point technology of spherical compressors, such as the Chinese patents with patent numbers 2013101006975 and the name "a turntable rotation synchronization mechanism for spherical compressors", patent number 201410100390X and the name "a spherical compressor rotor anti-dead mechanism" and patent number 2014105548366 and the name "a spherical compressor anti-dead power mechanism", among which patent number 20131010069 Patent No. 75 is to set a turntable synchronization mechanism consisting of an elastic steel ball and a concave slideway between the inner spherical surface of the cylinder body and the spherical surface of the turntable, and the elastic steel ball is used to instantaneously rotate the torque to make the rotor pass the dead point, but the concave slideway occupies the sealing surface, resulting in reduced sealing performance. At the same time, the concave slideway trajectory curve is complex and difficult to process; Patent No. 201410100390X is to set a concave slideway on the inner spherical surface of the cylinder body or the inner spherical surface of the cylinder seat, set a guide pin on the rotor, and provide the rotor rotation torque at the dead point through the guide pin. Although the sealing loss problem is solved, the concave slideway is difficult to process, and the structural parts are increased, and the structure is complex. Patent No. 2014105548366 is to set a track limit surface on the cylinder seat or the cylinder body, and set a power handle on the rotor. The torque of the rotor rotation is generated by the power handle and the track limit surface. However, the track limit surface processing points are complex, and the number of parts is increased, there are many vulnerable parts, and the structure is complex.

同时,由于球形压缩机是定容积比压缩机,专利号为200610104569.8的专利所述技术方案也不能实现变工况,无法在工况发生变化时高效工作。At the same time, since the spherical compressor is a constant volume ratio compressor, the technical solution described in the patent No. 200610104569.8 cannot achieve variable working conditions and cannot work efficiently when the working conditions change.

4)作为球形膨胀压缩机可用于二氧化碳压缩制冷,在活塞销座与转盘销座之间形成的一对工作室(第三腔室A和第三腔室B)作为膨胀工作室,压缩与膨胀机械运动相互作用,压缩工作室进行压缩行程时,膨胀工作室利用压缩级工作室运动趋势进行膨胀,使压缩和膨胀相互助力,膨胀机做功小,效率高,节能减排。4) As a spherical expansion compressor, it can be used for carbon dioxide compression refrigeration. A pair of working chambers (the third chamber A and the third chamber B) formed between the piston pin seat and the turntable pin seat serve as expansion working chambers. The compression and expansion mechanical movements interact with each other. When the compression working chamber performs a compression stroke, the expansion working chamber uses the movement trend of the compression-stage working chamber to expand, so that compression and expansion assist each other, the expander does less work, has high efficiency, and saves energy and reduces emissions.
