可选地，第二节流装置1051包括微型节流孔、毛细节流装置等。Optionally, the second throttling device 1051 includes a micro orifice, a capillary throttling device, and the like.
节流装置节流的原理为：液态冷媒将在节流装置处形成局部收缩，从而使流速液态冷媒增加，静压力降低，于是在节流装置前后产生了静压力差。进而使得液态冷媒逐渐降压变为气态冷媒，气态冷媒可以悬浮轴承101。The principle of throttling by the throttling device is: the liquid refrigerant will form a local contraction at the throttling device, so that the flow rate of the liquid refrigerant increases and the static pressure decreases, so a static pressure difference is generated before and after the throttling device. Furthermore, the pressure of the liquid refrigerant is reduced gradually to become a gas refrigerant, and the gas refrigerant can suspend the bearing 101 .
在实际应用中，由于压缩机10工作中，轴承101也会存在发热现象，供气管路103的液态冷媒也可以直接流至轴承101处，液态冷媒能够与轴承101换热，换热后液态冷媒变为气态冷媒。这样设置，不仅能够为轴承101供气，还能够冷却轴承101，保证轴承101的正常运转，进而保证压缩机10的可靠运动。In practical applications, since the compressor 10 is working, the bearing 101 will also generate heat, and the liquid refrigerant in the air supply pipeline 103 can also flow directly to the bearing 101, and the liquid refrigerant can exchange heat with the bearing 101.

第一冷却管路104内的液态冷媒在给电机102降温吸收电机102的热量后，气化为气态冷媒，第一冷却管路104内的压力增加。气态冷媒通过连通管路进入供气管路103，一方面可减少第一冷却管路104内的压力，使液态冷媒正常流通。另一方面通过连通管路向供气管路103补充气态冷媒，增加供气管路103内的气压，使轴承101悬浮，压缩机10正常工作。After the liquid refrigerant in the first cooling pipeline 104 cools down the motor 102 and absorbs the heat of the motor 102 , it is vaporized into a gaseous refrigerant, and the pressure in the first cooling pipeline 104 increases. The gaseous refrigerant enters the air supply pipeline 103 through the communication pipeline.

Similarly, when the flow rate of the liquid refrigerant decreases, the flow rate also decreases, and the pressure of the liquid refrigerant also decreases.
压缩机10还包括第二调节阀、第一检测装置和控制器；第二调节阀设于第一冷却管路104，用于调节第一冷却管路104的液态冷媒流量；第一检测装置设于供气管路103，以检测供气管路的压力。The compressor 10 also includes a second regulating valve, a first detection device and a controller; the second regulating valve is arranged on the first cooling pipeline 104, and is used to adjust the flow rate of the liquid refrigerant in the first cooling pipeline 104; the first detection device is provided in the gas supply pipeline 103 to detect the pressure of the gas supply pipeline.

本实施例中，供气管路103小于第一预设压力的情况下，供气管路103内液态冷媒的压力较小，会导致流至轴承101的冷媒压力较小，不足以悬浮轴承101，所以控制第二调节阀减小开度，减小第一冷却管路104的冷媒流量。同时控制第一调节阀增大开度，增加供气管路103的流量，以增加供气管路103的冷媒的压力，以保证流至轴承101的冷媒的压力能够悬浮轴承101。In this embodiment, when the air supply pipeline 103 is less than the first preset pressure, the pressure of the liquid refrigerant in the air supply pipeline 103 is relatively small, which will cause the pressure of the refrigerant flowing to the bearing 101 to be too small to suspend the bearing 101, so The opening of the second regulating valve is controlled to decrease to reduce the refrigerant flow rate of the first cooling pipeline 104 . At the same time, the opening of the first regulating valve is controlled to increase the flow rate of the air supply pipeline 103 to increase the pressure of the refrigerant in the air supply pipeline 103 to ensure that the pressure of the refrigerant flowing to the bearing 101 can suspend the bearing 101 .

本实施例中，在供气管路的压力大于或等于第一预设压力并小于或等于第二预设压力的情况下，供气管路103内的液态冷媒流至轴承101后的压力在轴承101所需的压力范围内，不仅能够悬浮轴承101，还不会损坏轴承101。控制器控制压力调节阀304保持开度，以保持供气管路103的冷媒压力。In this embodiment, when the pressure of the gas supply pipeline is greater than or equal to the first preset pressure and less than or equal to the second preset pressure, the pressure of the liquid refrigerant in the gas supply pipeline 103 after flowing to the bearing 101 is higher than that of the bearing 101 Within the required pressure range, not only the bearing 101 can be suspended, but also the bearing 101 will not be damaged. The controller controls the opening of the pressure regulating valve 304 to maintain the pressure of the refrigerant in the air supply pipeline 103 .
可选地，第一预设压力可以为轴承101所需压力的最小临界值，第二预设压力为轴承101所需压力的最大临界值。轴承101所需的压力的最小极限值为第三预设压力，轴承101所需的压力的最大极限值为第四预设压力。其中，第三预设压力小于第一预设压力，第四预设压力大于第二预设压力。Optionally, the first preset pressure may be the minimum critical value of the pressure required by the bearing 101 , and the second preset pressure may be the maximum critical value of the pressure required by the bearing 101 .

Wherein, the third preset pressure is lower than the first preset pressure, and the fourth preset pressure is higher than the second preset pressure.
本实施例中，考虑到供气管路103的液态冷媒调节压力后流至轴承101需要时间，特别是压缩机10启动阶段，轴承101处没有气态冷媒，为了避免轴承101处的气态冷媒压力不足，第三预设压力小于第一预设压力，以保证调节后的液态冷媒流至轴承101的过程中，轴承101不会损坏。同样的，为了避免轴承101处气态冷媒的压力过高，在供气管路的压力达到第二预设压力，控制器及时调小供气管路103的液态冷媒压力，避免轴承101处于所需压力的最大极限值，以对轴承101造成损坏。In this embodiment, considering that it takes time for the liquid refrigerant in the gas supply pipeline 103 to flow to the bearing 101 after the pressure is adjusted, especially during the start-up phase of the compressor 10, there is no gaseous refrigerant at the bearing 101. In order to avoid insufficient pressure of the gaseous refrigerant at the bearing 101, The third preset pressure is lower than the first preset pressure, so as to ensure that the bearing 101 will not be damaged when the adjusted liquid refrigerant flows to the bearing 101 . Similarly, in order to prevent the pressure of the gaseous refrigerant at the bearing 101 from being too high, when the pressure of the gas supply pipeline reaches the second preset pressure, the controller timely reduces the pressure of the liquid refrigerant in the gas supply pipeline 103 to prevent the bearing 101 from being under the required pressure.

本实施例中，电机102包括定子1021和转子1022，转子1022安装在定子1021内并能够相对于定子1021转动，在转子1022转动过程中，定子1021和转子1022均会发热，进而会导致电机腔1082的温度升高。第二检测装置通过检测电机腔1082的温度，控制器可以获得电机102的发热情况。In this embodiment, the motor 102 includes a stator 1021 and a rotor 1022. The rotor 1022 is installed in the stator 1021 and can rotate relative to the stator 1021. During the rotation of the rotor 1022, both the stator 1021 and the rotor 1022 will generate heat, which will cause the motor cavity 1082 temperature rise.

本实施例中，电机腔的温度越高，第二调节阀的开度越大，第一冷却管路104的冷媒流量增加，第一冷却管路104能够释放较多的液态冷媒至电机102处，以增加电机102的冷却效果。电机腔的温度较低时，第二调节阀的开度减小，第一冷却管路104的冷媒流量减小，进而减少流至电机102处的液态冷媒，放置流至电机102处的液态冷媒太多，汽化不充分，造成压缩机10内部积液，进而影响压缩机10的正常运行。In this embodiment, the higher the temperature of the motor cavity, the larger the opening of the second regulating valve, the greater the refrigerant flow rate of the first cooling pipeline 104, and the first cooling pipeline 104 can release more liquid refrigerant to the motor 102 , to increase the cooling effect of the motor 102. When the temperature of the motor cavity is low, the opening degree of the second regulating valve is reduced, and the refrigerant flow rate of the first cooling pipeline 104 is reduced, thereby reducing the liquid refrigerant flowing to the motor 102 and preventing the liquid refrigerant flowing to the motor 102 If it is too much, the vaporization will not be sufficient, resulting in liquid accumulation inside the compressor 10, thereby affecting the normal operation of the compressor 10.

The liquid supply system for a compressor includes the compressor 10 and the main refrigerant circuit of any one of the above embodiments, and the main refrigerant circuit A liquid intake port is provided, and the liquid intake port communicates with the liquid inlet port 110 through the liquid intake pipeline 30 .
本公开实施例的压缩机的供液***，因包括上述实施例中任一项的压缩机10，因而具有上述实施例中任一项的压缩机10的全部有益效果，在此不再赘述。The liquid supply system of the compressor in the embodiments of the present disclosure includes the compressor 10 in any one of the above-mentioned embodiments, so it has all the beneficial effects of the compressor 10 in any one of the above-mentioned embodiments, and will not be repeated here.
图1和图2中箭头表示压缩机的供液***中冷媒的流动方向。The arrows in Fig. 1 and Fig. 2 indicate the flow direction of the refrigerant in the liquid supply system of the compressor.
本公开实施例提供一种压缩机的供液***，压缩机的供液***包括主冷媒回路，主冷媒回路包括通过冷媒管路60相连通的压缩机10、冷凝器20、第三节流装置50和蒸发器40。冷媒管路60包括第一冷媒管路、第二冷媒管路和第三冷媒管路。An embodiment of the present disclosure provides a liquid supply system for a compressor. The liquid supply system for a compressor includes a main refrigerant circuit, and the main refrigerant circuit includes a compressor 10 , a condenser 20 , and a third throttling device connected through a refrigerant pipeline 60 50 and evaporator 40. The refrigerant pipeline 60 includes a first refrigerant pipeline, a second refrigerant pipeline and a third refrigerant pipeline.
蒸发器40通过第一冷媒管路60将低温低压的气态冷媒传递给压缩机10，压缩机10将低温低压的气态冷媒压缩为高温高压的气态冷媒，然后通过第二冷媒管路60将高温高压的气态冷媒传递给冷凝器20。高温高压的气态冷媒在冷凝器20散热后成为常温高压的液态冷媒。The evaporator 40 transmits the low-temperature and low-pressure gaseous refrigerant to the compressor 10 through the first refrigerant pipeline 60 , and the compressor 10 compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure gaseous refrigerant, and then passes the second refrigerant pipeline 60 to compress the high-temperature and high-pressure gaseous refrigerant. The gaseous refrigerant is delivered to the condenser 20. The high-temperature and high-pressure gaseous refrigerant becomes a liquid refrigerant at normal temperature and high pressure after the condenser 20 dissipates heat.
常温高压的液态冷媒经过第三冷媒管路和第三节流装置50后再次回到蒸发器40内。其中，常温高压的液态冷媒从第三节流装置50到达蒸发器40后空间突然增大，压力减小，变为低温低压的液态冷媒。低温低压的液态冷媒在蒸发器40内会发生汽化，变成低温低压的气态冷媒。之后蒸发器40再次通过第一冷媒管路将低温低压的气态冷媒传递给压缩机10，完成制冷循环。The normal temperature and high pressure liquid refrigerant returns to the evaporator 40 after passing through the third refrigerant pipeline and the third throttling device 50 . Wherein, the room-temperature and high-pressure liquid refrigerant reaches the evaporator 40 from the third throttling device 50 and the space suddenly increases, the pressure decreases, and the liquid refrigerant becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant will be vaporized in the evaporator 40 to become a low-temperature and low-pressure gaseous refrigerant. After that, the evaporator 40 transmits the low-temperature and low-pressure gaseous refrigerant to the compressor 10 again through the first refrigerant pipeline to complete the refrigeration cycle.
可选地，压缩机的供液***还包括排气管路701，排气管路701连通排气口109和蒸发器40，以将压缩机10内部冷却之后的气态冷媒和/或供气后的气态冷媒传递至蒸发器40内部。Optionally, the liquid supply system of the compressor also includes an exhaust pipeline 701, which communicates with the exhaust port 109 and the evaporator 40, so as to cool the gaseous refrigerant inside the compressor 10 and/or supply the gas The gaseous refrigerant is delivered to the inside of the evaporator 40 .
可选地，取液口设于冷凝器20，冷凝器20内的液态冷媒能够通过取液口流入取液管路30后，经进液口110进入压缩机10内部，液态冷媒在压缩机10内部能够变为气态冷媒，以悬浮轴承101并冷却电机102。Optionally, the liquid intake port is arranged in the condenser 20, and the liquid refrigerant in the condenser 20 can flow into the liquid intake pipeline 30 through the liquid intake port, and then enter the interior of the compressor 10 through the liquid intake port 110, and the liquid refrigerant in the compressor 10 The interior can be turned into a gaseous refrigerant to suspend the bearing 101 and cool the motor 102 .
采用本实施例的压缩机的供液***，从冷凝器20直接取液态冷媒直接供入压缩机10内部，节省了在压缩机10外部供气的供气罐、加热装置等部件，节省了能耗，优化了***。Adopting the liquid supply system of the compressor of this embodiment, the liquid refrigerant is directly taken from the condenser 20 and directly supplied to the interior of the compressor 10, which saves components such as an air supply tank and a heating device for supplying air outside the compressor 10, and saves energy. Consumption, optimize the system.
可选地，经进液口110流入的液态冷媒为高压液态冷媒，且高压液态冷媒的压力能够满足轴承101悬浮所需的压力，以减少液态冷媒进入压缩机10内部的压力调整。Optionally, the liquid refrigerant flowing in through the liquid inlet 110 is a high-pressure liquid refrigerant, and the pressure of the high-pressure liquid refrigerant can meet the pressure required for the bearing 101 to suspend, so as to reduce the pressure adjustment of the liquid refrigerant entering the compressor 10 .
可选地，冷凝器20包括液囊201，取液口设于液囊201。Optionally, the condenser 20 includes a liquid bag 201 , and the liquid intake port is arranged on the liquid bag 201 .
本实施例中，冷凝器20是主冷媒回路中液态冷媒压力最高的点，而液囊201是冷凝器20中液态冷媒压力最高点，因此液囊201是主冷媒回路中压力最高点。从液囊201中取液态冷媒，能够最大程度的保证液态冷媒的压力，一方面保证液态冷媒在第一取液管路301的流动，另一方面，节省加压装置3022的能耗，进而减少整个压缩机的供液***的能耗。In this embodiment, the condenser 20 is the point with the highest pressure of the liquid refrigerant in the main refrigerant circuit, and the liquid bag 201 is the point with the highest pressure of the liquid refrigerant in the condenser 20, so the liquid bag 201 is the point with the highest pressure in the main refrigerant circuit. Taking the liquid refrigerant from the liquid bag 201 can ensure the pressure of the liquid refrigerant to the greatest extent. On the one hand, it ensures the flow of the liquid refrigerant in the first liquid extraction pipeline 301. On the other hand, it saves the energy consumption of the pressurizing device 3022, thereby reducing The energy consumption of the liquid supply system of the entire compressor.
由于主冷媒回路正常运行时，液囊201处的液态冷媒的压力较高，大大减少了第二取液管路302的导通次数，也就减少了加压装置3022的开启次数和时间，大大优化了弗路设计。Since the pressure of the liquid refrigerant at the liquid bladder 201 is relatively high when the main refrigerant circuit is in normal operation, the number of conductions of the second liquid extraction pipeline 302 is greatly reduced, and the number and time of opening the pressurizing device 3022 are greatly reduced. Optimized the Flo design.
可选地，取液管路30包括第一取液管路301，第一取液管路301连通在进液口110和取液口之间，冷凝器20内的液态冷媒能够在冷凝器20和压缩机10的压力差的作用下， 经过第一取液管路301自主流入压缩机10内。Optionally, the liquid extraction pipeline 30 includes a first liquid extraction pipeline 301, and the first liquid extraction pipeline 301 is communicated between the liquid inlet 110 and the liquid extraction port, and the liquid refrigerant in the condenser 20 can flow in the condenser 20 Under the action of the pressure difference with the compressor 10 , it flows into the compressor 10 autonomously through the first liquid extraction pipeline 301 .
采用本实施例的压缩机的供液***，由于冷凝器20是主冷媒回路中液态冷媒压力最高位置，所以从冷凝器20直接取液态冷媒进入压缩机10内部，当冷凝器20内压力大于压缩机10内部压力时，液态冷媒可以在冷凝器20和压缩机10的压力差作用下由第一取液管路301内自主流入压缩机10内部。这样设置，节省了取液管路30驱动装置的设置，优化了***，节省了能耗。With the liquid supply system of the compressor of this embodiment, since the condenser 20 is the highest position of the liquid refrigerant pressure in the main refrigerant circuit, the liquid refrigerant is directly taken from the condenser 20 and enters the compressor 10. When the pressure in the condenser 20 is greater than the compression When the internal pressure of the compressor 10 is low, the liquid refrigerant can flow into the compressor 10 autonomously from the first liquid extraction pipeline 301 under the action of the pressure difference between the condenser 20 and the compressor 10 . Such setting saves the setting of the driving device of the liquid-taking pipeline 30, optimizes the system, and saves energy consumption.
可选地，在冷凝器20内液态冷媒的压力大于压缩机10的进液口110的压力的情况下，冷凝器20的液态冷媒可以通过取液口和第一取液管路301自主流入进液口110，进而进入压缩机10内部，无需驱动装置，节省了能耗。Optionally, when the pressure of the liquid refrigerant in the condenser 20 is greater than the pressure of the liquid inlet 110 of the compressor 10, the liquid refrigerant in the condenser 20 can flow into the inlet by itself through the liquid inlet and the first liquid inlet pipeline 301. The liquid port 110 further enters the interior of the compressor 10 without a driving device, which saves energy consumption.
由于进液口110和轴承101相连通，所述进液口110处的压力大于或等于轴承101处的压力，所以冷凝器20内液态冷媒的压力大于压缩机10的进液口110的压力的情况下，冷凝器20液态冷媒的压力也大于或等于轴承101的压力。本实施例中，在冷凝器20内液态冷媒的压力大于压缩机10的进液口110的压力的情况下，冷凝器20内的液态冷媒可以通过取液口和第一取液管路301自主流入进液口110，然后流至轴承101处。Since the liquid inlet 110 communicates with the bearing 101, the pressure at the liquid inlet 110 is greater than or equal to the pressure at the bearing 101, so the pressure of the liquid refrigerant in the condenser 20 is greater than the pressure at the liquid inlet 110 of the compressor 10. In some cases, the pressure of the liquid refrigerant in the condenser 20 is also greater than or equal to the pressure of the bearing 101 .
