Description

Technical Field

[0001] The invention relates to the technical field of heat transfer oil detection equipment, in particular to an online detection device for low-temperature heat transfer oil stability. Background Art

[0002] Low-temperature heat transfer oil generally refers to organic or inorganic compounds and mixtures thereof that can effectively transfer heat in a low-temperature environment. It has a low pour point and freezing point, ensuring that it can still be circulated normally in a cold environment. It is not easy to undergo chemical reactions such as decomposition and oxidation within the low temperature and normal operating temperature range. It has a long service life and can maintain stable performance during long-term use. The low-temperature heat transfer oil stability online detection device is mainly used to detect the stability of heat transfer oil in a low-temperature environment. The stored low-temperature heat transfer oil is regularly extracted for mechanical and physical testing to measure the basic performance and quality of the low-temperature heat transfer oil, thereby ensuring the operating stability of the equipment when using low-temperature heat transfer oil.

[0003] When the low-temperature heat transfer oil is stored statically, a small amount of different impurities exist inside it, which will produce stratified sedimentation due to their density differences. When the sediment accumulates to a certain extent and the low-temperature heat transfer oil is taken out for use, if the low-temperature heat transfer oil containing more impurity sediments in this stratification is used, it will affect the fluidity and heat conduction efficiency of the low-temperature heat transfer oil, and at the same time affect the operation of the equipment. However, the existing method for detecting low-temperature heat transfer oil usually adopts centrifugal separation. Although the centrifugal separation method can separate impurities relatively quickly, when the centrifugal separation is stopped, the impurities may still be redistributed, resulting in inaccurate detection results, thereby reducing the stability of the low-temperature heat transfer oil detection.

[0004] Therefore, an online detection device for low-temperature heat transfer oil stability is proposed. Summary of the invention

[0017] The present invention provides an online detection device for low-temperature heat transfer oil stability, which has the following technical points and beneficial effects:

[0018] 1. The present invention designs devices such as oil pipes, shunt pipes and shunt valves, and rotates the rotating disk to make the oil pipes rotate centrifugally. During the centrifugal process, according to the difference in density and quality between impurities and low-temperature heat transfer oil, low-temperature heat transfer oil and impurities in different situations will be discharged from the shunt pipe and shunt valve when the sealing slider slides down, and successively discharged to the inclined plate through the guide pipe, and then flow to the oil discharge pipe and the opening of the rotating disk. The flow time and flow rate of the low-temperature heat transfer oil and the impurity-containing mixed oil on the inclined plate are detected by the detection equipment to calculate the impurity content of the low-temperature heat transfer oil in different layers, and prevent the redistribution of impurities after the low-temperature heat transfer oil stops centrifuging.

[0019] 2. The present invention designs devices such as a shunt pipe, a shunt valve and an air pump. The straight-through hole connects the air valve port and the guide pipe relative to each other under the rotation of the shunt valve, and the right-angle through hole connects the oil discharge port relative to each other under the rotation of the shunt valve. Under the action of the air force blown out by the air pump, the gas is blown out from the oil discharge port and the guide pipe through the straight-through hole and the right-angle through hole, thereby blowing out the low-temperature heat transfer oil sample remaining in the oil discharge port and the guide pipe. When the gas is blown out from the guide pipe to blow out the low-temperature heat transfer oil, the gas blown out of the guide pipe acts on the inclined plate to blow out the low-temperature heat transfer oil sample on the inclined plate. At the same time, the heat transfer plate conducts and cools down part of the surrounding gas. When the docking rod sucks out the gas in the detection chamber, the cooled gas enters the detection chamber to reduce the temperature in the detection chamber, so as to further reduce the interference of the temperature on the detection of the low-temperature heat transfer oil.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 10 The present invention provides a technical solution for an online detection device for low-temperature thermal oil stability:

[0035] A low-temperature heat transfer oil stability online detection device comprises a transmission device 101 and a transmission shaft 1011 vertically installed in the transmission device 101, and a rotating disk 6 movably arranged on the transmission shaft 1011, an oil drain pipe 105 is movably installed in the transmission device 101, and the oil drain pipe 105 movably runs through the inside of the transmission shaft 1011 and is fixedly connected to the rotating disk 6, fixed rods 1012 are equidistantly fixedly installed on the outside of the transmission shaft 1011, and a transmission shift block 1013 is movably connected above the fixed rod 1012, and the fixed rod 1012 and the transmission shift block 1013 are movably connected through a connecting shaft provided with a torsion spring, a transmission tooth 602 is equidistantly fixedly installed below the rotating disk 6, and the transmission tooth 602 and the transmission shift block 1013 are meshingly movably connected, and an oil pipe 7 is equidistantly fixedly installed above the rotating disk 6;

[0036] As an embodiment of the present invention, Figures 3 to 7As shown, a servo motor 102 for providing power is fixedly installed on one side of the transmission 101, a transmission disk 103 is fixedly connected to the driving shaft of the servo motor 102 and the transmission shaft on one side of the transmission 101, and a transmission belt 104 for transmission is provided between the two transmission disks 103, an opening is penetrated through the middle inner side of the oil discharge pipe 105 and the rotating disk 6, and an inclined plate 601 connected to the opening is equidistantly arranged on the rotating disk 6, and the guide pipes 13 are all arranged above one side of the inclined plate 601, an air pump 106 is fixedly connected to one side of the transmission 101, and the air pump 106 is in driving connection with the transmission shaft on the transmission 101, an air guide pipe 107 is fixedly installed on the air pump 106, a collecting disk 108 is provided below the rotating disk 6, and the collecting disk 108 is fixedly connected to the transmission 101;

[0037] When working, the servo motor 102 is operated to provide power, and the servo motor 102 driving shaft drives the transmission disc 103 to rotate synchronously. The transmission belt 104 is installed between the transmission disc 103 and the transmission device 101, so that the servo motor 102 provides power to the transmission device 101 through the transmission disc 103 and the transmission belt 104 to drive the transmission device 101 to operate. When the servo motor 102 rotates forward to drive the transmission device 101 to operate, the transmission shaft 1011 is driven to rotate through the transmission parts inside the transmission device 101. When the transmission shaft 1011 rotates, the fixed parts equidistantly fixed on the outside thereof are The fixed rod 1012 will also rotate accordingly. Since the fixed rod 1012 is connected to the transmission block 1013 by tilting through a connecting shaft provided with a torsion spring, the torsion spring at this time will give elastic force to the transmission block 1013 to keep it in meshing with the transmission tooth 602 below the rotating disk 6. As the transmission shaft 1011 rotates, the transmission block 1013, driven by the fixed rod 1012, drives the rotating disk 6 to mechanically rotate and operate, so as to centrifugally rotate the oil pipe 7 filled with low-temperature heat transfer oil. When the servo motor 102 rotates in the reverse direction to drive the transmission 101 to operate, the transmission block 1013 is tilted. The transmission gear 602 slides in contact with it. Secondly, when the servo motor 102 rotates in the forward direction to drive the transmission device 101 to operate, the transmission of the transmission device 101 to the air pump 106 makes it perform an inefficient suction operation. When the servo motor 102 rotates in the reverse direction to drive the transmission device 101 to operate, the air pump 106 performs an efficient inflation operation. Since the rotating disk 6 is provided with an inclined plate 601 and a collecting plate 108 is provided below the rotating disk 6, when the low-temperature heat transfer oil containing impurities is detected, if the impurity density is large and the mass is heavy, the low-temperature heat transfer oil is preferentially discharged on the inclined plate through the guide pipe 13. 601 and falls into the openings on the oil drain pipe 105 and the rotating disk 6. If the impurity density is small and the mass is light, the low-temperature heat transfer oil mixture doped with such impurities is preferentially discharged through the guide pipe 13 and falls into the openings on the oil drain pipe 105 and the rotating disk 6 on the inclined plate 601. Since the fluidity of the low-temperature heat transfer oil doped with impurities is slower than that of the relatively pure low-temperature heat transfer oil, the flow time and flow rate of the low-temperature heat transfer oil discharged successively on the inclined plate 601 are used to facilitate the detection equipment to perform detection and record above the detection chamber 2, so as to calculate and measure the impurity content of the low-temperature heat transfer oil in different layers.

[0038] As an embodiment of the present invention, Figures 4 to 12As shown, an oil drain port 701 is provided below the oil pipe 7, and the oil drain port 701 is set through the rotating disk 6, a sealing slider 702 is movably installed on the upper part of the oil pipe 7, and an air passage 705 is equidistantly penetrated on the sealing slider 702, a sealing sheet 704 is movably connected in the middle of the sealing slider 702, a connecting shaft 703 with a torsion spring is fixedly connected above the sealing sheet 704, and the sealing sheet 704 is movably connected to the sealing slider 702 through the connecting shaft 703, and an air valve 707 is movably installed on the inner side of the air passage 705, and one side of the air valve 707 is connected to the sealing sheet 70 4 is fitted, the other side of the gas valve 707 is fixedly connected with a spring member 706, and the spring member 706 is fixedly connected with the sealing slider 702, a shunt pipe 11 is fixedly installed between the oil pipe 7 and the oil discharge port 701, and a shunt valve 12 is movably installed on the inner side of the shunt pipe 11, a gas-passing valve port 1101 is fixedly installed on one side of the shunt pipe 11, and a connecting shaft 703 with a torsion spring and a sealing sheet 704 structure are provided on the inner side of the gas-passing valve port 1101, a guide pipe 13 is fixedly connected to the other side of the shunt pipe 11, and a straight through hole 1201 and a right-angle through hole 1202 are provided in the middle of the shunt valve 12;

[0039] During operation, before the low-temperature heat-conducting oil to be tested is injected into the oil pipe 7, the electrically driven telescopic rod 202 drives the docking rod 203 to extend so as to be embedded in the air valve port 1101 and to be aligned with the right-angle through hole 1202. Since the docking rod 203 is embedded in the air valve port 1101, the rotating disk 6 is limited so that the rotating disk 6 is not driven to rotate when the transmission shift block 1013 is reversed. At this time, the docking rod 203 pushes the sealing sheet 704 structure in the air valve port 1101 to open. Under the reverse drive of the servo motor 102, the air pump 106 inflates the docking rod 203 with gas through the air channel in the air guide pipe 107, the test table 1 and the test chamber 2, and pushes the sealing slider 702 that falls to the bottom of the oil pipe 7 under the action of gravity upward to the top by force (even if part of the gas is discharged by the straight through hole 1201, it will not affect the gas pushing the sealing slider 702 upward to the top of the oil pipe 7, because when the air pump 106 operates efficiently A lot of gas is generated). At this time, the electric driver provided on the diverter pipe 11 drives the diverter valve 12 to rotate, so that the side of the diverter valve 12 without the straight hole 1201 and the right-angle through hole 1202 rotates upward to seal the oil pipe 7. At the same time, the straight hole 1201 connects the gas valve port 1101 with the guide pipe 13 under the rotation of the diverter valve 12, and the right-angle through hole 1202 connects with the oil discharge port 701 under the rotation of the diverter valve 12. , under the action of the air force blown out by the air pump 106, the gas can be blown out from the oil discharge port 701 and the flow guide pipe 13 through the straight through hole 1201 and the right-angle through hole 1202, thereby blowing out the low-temperature heat transfer oil sample remaining inside the oil discharge port 701 and the flow guide pipe 13. When the gas is blown out from the flow guide pipe 13 to blow out the low-temperature heat transfer oil, the gas blown out of the flow guide pipe 13 acts on the inclined plate 601 to blow out the low-temperature heat transfer oil sample on the inclined plate 601;

[0040] When the low-temperature heat transfer oil to be tested is injected into the oil pipe 7, it is inserted into the sealing slider 702 through the oil filling pipe 802. At this time, due to the high pressure of the gas filled into the oil pipe 7 during inflation, when the oil filling pipe 802 is inserted into the sealing slider 702 to squeeze and open the sealing sheet 704, the sealing slider 702 will not slide downward due to the insertion of the oil filling pipe 802. At this time, the sealing sheet 704 pushes the air valve 707 to slide inward under the connection between the connecting shaft 703 and the sealing slider 702, so that the air valve 707 The through hole on the upper side overlaps with the gas vent 705, so that the gas can be discharged when the low-temperature heat-conducting oil is injected into the oil injection pipe 802. When the low-temperature heat-conducting oil in the oil pipe 7 is injected through the oil injection pipe 802, the oil injection pipe 802 is pulled out from the sealing slider 702. At this time, the air valve 707, under the action of the spring member 706, makes the through hole and the gas vent 705 staggered and sealed. At the same time, the sealing sheet 704 rebounds and fits and seals each other under the action of the connecting shaft 703 containing the torsion spring, so as to prevent the low-temperature heat-conducting oil in the oil pipe 7 from overflowing under the centrifugal action.

[0041] If the low-temperature heat transfer oil contains a large amount of impurities or the content of active substances contained therein is abnormal, when the oil filling pipe 802 injects the low-temperature heat transfer oil into the oil pipe 7, the low-temperature heat transfer oil injected into the oil pipe 7 will produce a lot of foam. At this time, the electric driver drives the diverter valve 12 to rotate so that the straight hole 1201 connects the oil discharge port 701 and the oil pipe 7 to each other, so as to directly discharge the low-temperature heat transfer oil of poor quality, and collect the low-temperature heat transfer oil of poor quality discharged from the oil discharge port 701 through the collecting plate 108 under the rotating plate 6. When the low-temperature heat transfer oil in the oil pipe 7 is centrifuged, at this time, the impurities with larger density and heavier mass are distributed to the outside, and the low-temperature heat transfer oil is distributed to the inside, and the impurities with smaller density and lighter mass are distributed to the inside, and the low-temperature heat transfer oil is distributed to the outside. Then, when the electric driver drives the diverter valve 12 to rotate so that the right-angle through hole 1202 is relative to the guide pipe 13, the impurities are successively discharged. and the low-temperature heat transfer oil is discharged to detect the impurity content of impurities with different densities and masses in different layers (because the fluidity of the oil mixed with impurities after stratification is poor, when the opening size of the guide tube 13 is the same, it flows on the inclined plate 601 for a longer time, while the low-temperature heat transfer oil after stratification has fewer or no impurities, and its fluidity is stronger, and it flows on the inclined plate 601 for a shorter time. At this time, the oil mixed with impurities and the relatively pure low-temperature heat transfer oil will have obvious flow rate changes on the inclined plate 601 under centrifugal stratification, which is convenient for monitoring by the detection equipment). At the same time, when the straight hole 1201 connects the oil pipe 7 and the oil discharge port 701, or the right-angle through hole 1202 connects the oil pipe 7 and the guide tube 13, the sealing slider 702 slides downward under the action of gravity to discharge the low-temperature heat transfer oil and the low-temperature heat transfer oil mixed liquid, and scrape off the low-temperature heat transfer oil sample on the inner wall of the oil pipe 7.

[0042] As an embodiment of the present invention, Figures 1 to 3 As shown, an inspection chamber 2 is provided on the outer side of the rotating disk 6, and a chamber door 201 is movably installed on one side of the inspection chamber 2, an inspection platform 1 is fixedly installed below the inspection chamber 2, and a transmission device 101 is fixedly installed inside the inspection platform 1, air passages are provided inside the inspection platform 1 and the inspection chamber 2, and the air passages inside the inspection platform 1 and the inspection chamber 2 are connected with the air guide tube 107, electric-driven telescopic rods 202 are equidistantly fixedly installed inside the inspection chamber 2, a docking rod 203 is movably installed on the inner side of the electric-driven telescopic rod 202, the air guide tube 107 is connected with the docking rod 203 through the air passage, and the docking rod 203 is movably connected with the air valve port 1101;

[0043] During operation, the detection chamber 2 is used to protect the oil pipe 7 when the rotating disk 6 is centrifugally rotated, and the chamber door 201 is opened to clean the oil collected in the collection disk 108, or after the centrifugation is completed, the diverter valve 12 is manually rotated through the turning handle on the diverter valve 12, with the alignment direction of the hole-shaped straight through hole 1201 or the right-angle through hole 1202 (the same as above). When in use, the transmission device 101 is installed on the detection table 1 for use, and the low-temperature heat-conducting oil discharged from the oil discharge pipe 105 is collected through the collection bucket under the detection table 1. When the low-temperature heat-conducting oil in the oil pipe 7 is centrifugally rotated, the electric drive telescopic rod 202 draws the docking rod 203 out of the air valve port 1101 to avoid rotation collision. At the same time, the servo motor 102 rotates forward to rotate the rotating disk 6 During centrifugal rotation, the air pump 106 rotates forward synchronously to generate a lower suction force, and the gas in the detection chamber 2 is sucked out through the air channel and the air guide pipe 107 through the docking rod 203. The refrigerator 10 provided above (the refrigerator 10 is used here to connect the low-temperature heat transfer oil in the oil pipe 8 to maintain the low temperature, and can be a semiconductor refrigerator or other refrigeration equipment. The refrigerator 10 is a prior art and will not be described in detail here) generates low temperature and conducts cooling through the temperature conduction plate 5 to the oil pipe 8 to maintain the detection temperature of the low-temperature heat transfer oil. At the same time, the temperature conduction plate 5 conducts cooling to part of the surrounding gas. When the docking rod 203 sucks out the gas in the detection chamber 2, the cooled gas enters the detection chamber 2 to lower the temperature in the detection chamber 2, so as to further reduce the interference of the temperature on the detection of the low-temperature heat transfer oil.

[0044] As an embodiment of the present invention, Figures 1 to 8 As shown, a support rod 3 is fixedly installed above the detection chamber 2, and an oil receiving pipe 8 is fixedly connected in the middle of the support rod 3, a driving turntable is provided below the oil receiving pipe 8, and a lifting rod 801 is provided below the driving turntable and is connected to the oil receiving pipe 8, an oil filling pipe 802 is fixedly installed on one side of the lifting rod 801, an oil receiving port 803 is provided through one side of the oil receiving pipe 8, and the oil receiving port 803 is connected to the oil filling pipe 802 through the oil receiving pipe 8 and the lifting rod 801, a driver 9 is fixedly installed above the oil receiving pipe 8, a driving gear 901 is movably installed on one side of the driver 9, and the driving gear 901 is meshed and connected with the oil filling pressure rod 4, a heat conduction plate 5 is nested on the outer side of the oil receiving pipe 8, and a refrigerator 10 is fixedly installed on one side of the heat conduction plate 5;

[0045] During operation, the oil pipe 8 is installed and used through the support rod 3, and the driver 9 is installed on the oil pipe 8 for use. When filling oil, the oil receiving port 803 is connected to the external delivery pump through the external connecting conduit, and the low-temperature heat transfer oil of different layers stored in the storage device is gradually sucked out into the oil pipe 8 in sequence through the external delivery pump. At this time, the driving gear 901 drives the driver 9 to move the oil filling pressure rod 4 into the oil pipe 8, and then each section of low-temperature heat transfer oil of different layers in the oil pipe 8 is injected into the lifting rod 801, and injected into the oil pipe 7 under the inserted sealing slider 702 through the oil filling pipe 802. Secondly, the lifting rod 801 is rotated by the driving turntable under the oil pipe 8, and then the position of the oil filling pipe 802 is adjusted, so that the oil filling pipe 802 can be inserted into different sealing sliders 702 when the inspection table 1 is telescopic.

[0046] Working principle: During operation, during the centrifugal rotation of the oil pipe 7 by the rotating disk 6, the detection chamber 2 is used for protection, and the detection chamber 2 is opened through the chamber door 201 to clean the oil collected in the collection plate 108. After the centrifugation is completed, the diverter valve 12 is manually rotated by the turning handle on the diverter valve 12, and the actuator 101 is installed on the detection table 1 in the direction of the hole-shaped straight through hole 1201 or the right-angle through hole 1202 for use. A collection bucket can be placed under the detection table 1 to collect the low-temperature heat conduction discharged from the oil discharge pipe 105. When the low-temperature heat-conducting oil in the oil pipe 7 is centrifugally rotated, the electrically driven telescopic rod 202 draws the docking rod 203 out of the gas valve port 1101 to avoid rotation collision. At the same time, when the centrifugal rotation is performed, the positive rotation causes the air pump 106 to generate a lower suction force, so that the docking rod 203 sucks the gas in the detection chamber 2 out of the air pump 106 through the air channel and the air guide pipe 107. The refrigerator 10 generates a low temperature and conducts cooling through the temperature conduction plate 5 docking oil pipe 8 to maintain the detection temperature of the low-temperature heat-conducting oil. The temperature conduction plate 5 has a certain effect on the surrounding parts. The gas is conducted to cool down, and when the docking rod 203 sucks out the gas in the detection chamber 2, the cooled gas enters the detection chamber 2 to reduce the temperature in the detection chamber 2, so as to further reduce the interference of the temperature on the low-temperature thermal oil detection. The oil pipe 8 is connected to the support rod 3 for installation and use, and the driver 9 is installed on the oil receiving pipe 8 for use. When filling oil, the oil receiving port 803 is connected to the external delivery pump through the external connecting conduit, and the low-temperature thermal oil stored in different layers in the storage is gradually sucked out to the oil receiving pipe 8 in sequence through the external delivery pump. At this time, the driving gear 901 drives the driver 9 to move the oil injection rod 4 into the oil receiving pipe 8, and then the low-temperature heat transfer oil of each section in the different layers of the oil receiving pipe 8 is injected into the lifting rod 801, and then injected into the oil pipe 7 under the inserted sealing slider 702 through the oil injection pipe 802. Then, the lifting rod 801 is rotated by the driving turntable under the oil receiving pipe 8, and the position of the oil injection pipe 802 is adjusted, so that the oil injection pipe 802 can be inserted into different sealing sliders 702 when the inspection platform 1 is telescopically operated;

[0047] The servo motor 102 is used to provide power, and the drive shaft of the motor drives the transmission disc 103 to rotate synchronously. The transmission belt 104 is installed between the transmission disc 103 and the transmission device 101, so that the servo motor 102 transmits power to the transmission device 101 through the transmission disc 103 and the transmission belt 104, thereby driving the transmission device 101 to operate. When the servo motor 102 rotates forward to drive the transmission device 101, the transmission member inside the transmission device 101 rotates the transmission shaft 1011, and the transmission shaft 1011 rotates. The rotation of 011 drives the fixed rod 1012 which is fixedly installed equidistantly outside to rotate. At this time, the torsion spring applies elastic force to the transmission shift block 1013 to keep it in meshing tendency with the transmission tooth 602 below the rotating disk 6. Driven by the fixed rod 1012, the transmission shift block 1013 pushes the rotating disk 6 to perform mechanical rotation, thereby performing centrifugal rotation operation on the oil pipe 7 filled with low-temperature heat transfer oil. When the servo motor 102 rotates in the opposite direction to drive the transmission device 101, the transmission shift block 1013 is in mesh with the inclined transmission gear 602. The teeth 602 slide in close contact. In addition, when the servo motor 102 rotates forward to drive the actuator 101, the actuator 101 will drive the air pump 106 to perform an inefficient suction operation; and when the servo motor 102 rotates reversely to drive the actuator 101, the air pump 106 performs an efficient inflation operation. When detecting low-temperature heat transfer oil containing impurities, if the impurity density is large and the mass is heavy, the low-temperature heat transfer oil will be discharged through the guide pipe 13 first, and flow along the inclined plate 601 to the oil discharge pipe 10 5 and the opening on the rotating disk 6; if the impurity density is small and the mass is light, the low-temperature heat transfer oil mixture containing the impurity will be discharged through the guide pipe 13 first, and flow along the inclined plate 601 to the oil discharge pipe 105 and the opening on the rotating disk 6. Since the low-temperature heat transfer oil doped with impurities has a slower fluidity than pure oil, the detection equipment can detect and record the flow time and flow rate of the low-temperature heat transfer oil discharged successively on the inclined plate 601 above the detection chamber 2 to calculate the impurity content of the low-temperature heat transfer oil in different layers;

[0048] Before injecting the low-temperature heat-conducting oil to be tested into the oil pipe 7, the electrically driven telescopic rod 202 drives the docking rod 203 to extend so as to be embedded in the air valve port 1101 and aligned with the right-angle through hole 1202. The function of the docking rod 203 is to push the sealing sheet 704 in the air valve port 1101 to open. Under the reverse drive of the servo motor 102, the air pump 106 inflates the docking rod 203 through the air channel in the air pipe 107, the test bench 1 and the test chamber 2. Under the action of gravity, the sealing slider 702 originally located at the bottom of the oil pipe 7 is pushed to the top by air force. Then, the electric driver on the diverter pipe 11 drives the diverter valve 12 to rotate, so that the diverter valve 12 without the straight through hole 120 is not provided. 1 and one side of the right-angle through hole 1202 are facing upwards, thereby sealing the oil pipe 7. At the same time, the straight hole 1201 is aligned and connected with the guide pipe 13 under the rotation of the diverter valve 12, and the right-angle through hole 1202 is aligned and connected with the oil discharge port 701. Under the action of the air force blown out by the air pump 106, the gas is blown out from the oil discharge port 701 and the guide pipe 13 through the straight hole 1201 and the right-angle through hole 1202 to remove the low-temperature heat transfer oil sample remaining in the oil discharge port 701 and the guide pipe 13. When the gas is blown out from the guide pipe 13 to remove the low-temperature heat transfer oil, the gas blown out of the guide pipe 13 acts on the inclined plate 601 to remove the low-temperature heat transfer oil sample on the inclined plate 601.

[0049] When the low-temperature heat-conducting oil to be tested is injected into the oil pipe 7, the oil injection pipe 802 is inserted into the sealing slider 702, thereby squeezing the sealing sheet 704 to open. Due to the insertion of the oil injection pipe 802, the sealing slider 702 will not slide downward. Under the connection between the connecting shaft 703 and the sealing slider 702, the air valve 707 is pushed to slide inward, so that the through hole on the air valve 707 overlaps with the air vent 705, so that the gas is discharged when the low-temperature heat-conducting oil is injected into the oil injection pipe 802. When the low-temperature heat-conducting oil in the oil pipe 7 passes through the oil injection pipe, the sealing slider 702 will not slide downward. After the injection of 802 is completed, the oil injection pipe 802 is pulled out from the sealing slider 702. At this time, the air valve 707, under the action of the spring member 706, makes the through hole and the air port 705 staggered and sealed. At the same time, the sealing sheet 704 rebounds and fits the seal under the action of the connecting shaft 703 containing the torsion spring to prevent the low-temperature heat transfer oil in the oil pipe 7 from overflowing under the centrifugal effect. If the low-temperature heat transfer oil contains a large amount of impurities or an abnormal amount of active substances, more foam will be generated when the oil injection pipe 802 injects the low-temperature heat transfer oil into the oil pipe 7. At this time, The electric driver drives the diverter valve 12 to rotate, so that the through hole 1201 connects the oil discharge port 701 and the oil pipe 7 to each other, so as to directly discharge the low-temperature heat transfer oil of poor quality, and collect the discharged low-temperature heat transfer oil through the collecting plate 108 under the rotating plate 6. After the low-temperature heat transfer oil in the oil pipe 7 is centrifuged, the impurities with larger density and heavier mass are distributed to the outside, while the low-temperature heat transfer oil is distributed to the inside, and the impurities with smaller density and lighter mass are distributed to the inside, and the low-temperature heat transfer oil is distributed to the outside. Then, the electric driver Drive the diverter valve 12 to rotate so that the right-angle through hole 1202 is aligned with the guide tube 13, and impurities and low-temperature heat transfer oil are discharged in turn, and impurities with different densities and masses in different layers are detected. At the same time, when the straight through hole 1201 connects the oil pipe 7 with the oil discharge port 701, or the right-angle through hole 1202 connects the oil pipe 7 with the guide tube 13, the sealing slider 702 slides downward under the action of gravity to discharge the low-temperature heat transfer oil and the low-temperature heat transfer oil mixed liquid, and scrape the low-temperature heat transfer oil sample on the inner wall of the oil pipe 7.
