New Description: • [New Technology Area] This creation is about a bearing and rotor lubrication device, especially a bearing and rotor lubrication device used in an expansion machine in the Rankine cycle. [Prior Art] Generally speaking, in the process of refrigerant treatment in the refrigeration cycle system, it will be treated with a compressor to become a high-temperature high-pressure gaseous refrigerant, and then exchanged with the external fluid through the φ condenser to form a high pressure. The warm liquid refrigerant 'and the semi-season expander is the reverse cycle used in the compression cycle system'. Its function is to expand the high-pressure high-temperature liquid refrigerant. Before entering the expander, the high-temperature and high-pressure gas refrigerant expands and leaves the expander. The low-temperature low-temperature gaseous refrigerant enters the condenser. After heat exchange through the condenser, the refrigerant is in the state of low pressure and low temperature liquid refrigerant at the outlet end of the condenser, and then the low pressure and medium temperature liquid refrigerant is sent to the evaporator by the booster pump, and finally in the evaporator. From the low pressure medium temperature to the high pressure high temperature gas and then sent to the expansion machine 'this is cold; the complete cycle of the reverse cycle in the East cycle, also known as the Rankine cycle. In the prior art, in addition to the refrigerant, the refrigerant in the Rankine cycle is mixed with the circulating oil circulating in the circulation. The purpose of the refrigeration oil is to lubricate the rotor and bearing of the semi-season expander. Oil and refrigerant will mix, which will affect the lubrication of the bearing and rotor of the refrigerating oil, shortening the service life of the bearing and the rotor. This will not only affect the overall cycle of M425258, but also improve the replacement frequency of the bearing and rotor. In order to cope with this situation, the oil separator and the oil spring are designed to separate the refrigeration oil and the refrigerant circulating from the expander with the oil separator. The oil pump is used to guide the cold oil back to the expander to increase lubrication. The amount of oil used was found to be a defect. However, after passing through the oil separator, there will still be a small part of the cold oil that will be mixed in the cold and cycled together when circulating to the heat exchanger. The frozen oil will slowly accumulate in the heat exchanger for a long time, and the accumulated amount will increase 'may block the pipeline, which will affect the heat exchange rate of the evaporator and reduce it. The refrigeration oil in the expander, the effect of reducing lubricated bearings and rotors. In view of this, the creators of this case have accumulated experience based on years of research, and with their own creativity and continuous experimentation, developed an expansion machine bearing and rotor that can effectively improve the defects mentioned in the above-mentioned prior art.

The expander bearing and rotor lubrication device comprises: M425258 J * a first circuit comprising: a condenser; a booster pump connected to the condenser by a pipeline; and an evaporator connected to the pipeline by the pipeline The booster pump can guide a working fluid in the condenser to the evaporator by a boosting system; an expander is connected to the evaporator by a pipeline; and an oil separator, The pipeline is connected to the expander and the condenser; - - - - - - - . _________ _____ __. A second loop is connected in parallel to the expander and the oil separator, and comprises: a first filter, which is a pipeline Connected to the oil separator; an oil pump is connected to the first filter by a _S line, and is connected to the oil separator 'and a second filter by another line, and is connected to the oil pump and the expander by a pipeline And a gas guiding pipe, which is connected in parallel to the bottom of the evaporator and the expander has a pressure difference between the evaporator and the expander, so that the working fluid accumulated in the evaporator can be transported by the oil guiding pipe. In addition, there is a third one. The ferrite is disposed on the oil guiding pipe; wherein, by applying a nut, the working fluid separated from the oil separator can be introduced into the expander. [Embodiment] In order to more clearly describe an expansion proposed by the present invention The machine bearing and the rotor lubricating device, the preferred embodiments of the present invention will be described in detail below with reference to the drawings. At the same time, referring to the first drawing, a schematic diagram of a first preferred embodiment of the present invention relates to an expansion machine bearing and a rotor lubricating device, which comprises: a first circuit, a system comprising: - a condenser 1 boost The pump 2 is connected by a pipeline to the M425258 々 the condenser 1; an evaporator 3 is connected to the booster pump 2 by a pipeline, and the working fluid of the condenser 1 can be guided by the booster pump 2 Bowing into the evaporator 3, wherein the working fluid system is formed by a refrigerant and a refrigeration oil group; an expander 4 is connected to the evaporator 3 by a pipeline; and an oil separator 5' is connected by a pipeline Connected to the expander 4 and the condenser 1; a second circuit connected in parallel to the expander 4 and the oil separator 5' comprises: a first filter 61 connected to the oil separator 5 by a pipeline; The oil pump 7 is connected to the first filter 61 by a pipeline, and is connected to the oil separator 5 by another pipeline; and a second filter 62 is connected to the oil pump 7 and the expander 4 by a pipeline; The oil guiding pipe 8 is connected in parallel to the bottom pipe of the evaporator 3 and the expander 4, # has a pressure difference between the evaporator 3 and the expander 4 The refrigerating oil is made to pass through the oil guiding tube 8 to make a transfer wheel, and further, a third filter 63 is disposed on the oil guiding tube 8. On the s δ, wherein 'the oil sump at the bottom of the expander 4 is avoided Accumulating too much oil in the oil tank method, Putian said that a line 9 is connected to the expander 4 in the blue surface; and because the excessive oil quantity is avoided to affect the engine (not shown), a line 10 is connected at the bottom of the motor end. The expansion service machine 4 is connected to the 'line 9' 10 and then collected into the oil separator 5; the following oblique material company, person * for the refrigerant and the refrigeration oil circulation process for a detailed description, cold - 7 media will The first loop is circulated, and when the refrigerant flows through the condenser 1, the Shez Aim is guided to the evaporator 3 by the pressurization of the booster pump 2, and then flows from the evaporator 3 to block the ground, ·& The brain expander 4 then reaches the oil separator 5; on the other hand, the 'refrigerant oil will be injected into the oil separator 5 from the outer PP. When the system is running, the M425258 and the cold oil will be mixed with the refrigerant. 5 will separate the refrigerant and the frozen oil from the frozen oil that will be separated from the oil separator 5 The second loop (after entering the second loop as shown by the dashed line in the first figure, first flows through the first filter 61, and the first filter 61 will make the impurities in the frozen oil. The oil pump 7 is circulated, since the pressure in the expander 4 is greater than the relationship of the oil separator 5, the refrigerant oil cannot be directly returned from the oil separator 5 to the expander 4, and at this time, the refrigerant oil is pressurized by the oil pump 7. Returned to the inside of the expander 4 to assist in lubricating the rotor and the bearing to compensate for the shortage of the frozen oil and the excessive wear of the rotor and the bearing, thereby increasing the bearing life. Among them, before the refrigerant oil is pressurized and sent back to the expander 4 from the oil pump 7, After passing through the second filter 62, the refrigerating oil is again filtered. [The impurities are filtered out and then injected into the expander 4'. Further, the oil passage entering the expander 4 is divided into two parts. One is the bearing pair injected into the inside of the expander 4. The bearing is lubricated, and the other pipe is injected into the expansion chamber in the expander 4 to lubricate the rotor. The refrigerating oil injected into the expander _ 4 is recirculated to the oil separator 5 according to the first circuit; After 5, though Here, the refrigerant is separated from the refrigerant, but there will still be a small part of the frozen oil mixed in the refrigerant, circulating in the ancestral road. 'When a little cold oil comes from the condenser i through the booster 2 input to the evaporator 3 When the cold oil pattern is generated in the evaporator 3, if a large amount of cold oil is accumulated, the heat exchange rate of the entire cycle is affected, so the oil pipe 8 between the evaporator 3 and the expander 4 is utilized and connected. By the evaporator 3 being in a high pressure state, and the expander 4 being in a medium-high pressure state, the two-staged M4Z5258's frozen oil which is circulated from the evaporator 3 by the tube 8 is directly introduced into the oil separator 5 for separation, and is simultaneously removed. Evaporating the internal cold oil content of $3, increasing the heat exchange rate inside the evaporator 3, increasing the amount of refrigeration oil flowing into the interior of the expander 4, assisting the lubrication of the bearing and the rotor, and further, cooling in the evaporator-3 When the bundle of oil flows back to the oil separator 5 via the oil conduit 8, the third filter 63 in the oil conduit 8 also filters the impurities of the refrigeration oil. The above has made a fairly complete disclosure of the creation, in combination with the above, • X can learn that the advantage of this creation is that by adding a guide oil pipe 8, the refrigeration oil which will be accumulated in the interior of the evaporator 3 during the recycling process is utilized. Clearing the hoisting evaporator 3 (4) cold; East oil, lifting the heat exchange rate of the evaporator 3, more progressively using the oil guiding pipe 8 to transport the removed cold oil to the inside of the expander 4, increasing the refrigeration oil inside the expander 4, To improve the lubrication of the rotor and bearings.
