[0020] Figure 2 Schematic diagram of the lubricant pumping system provided by the embodiment of the present invention. Detailed implementation manners

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Apparently, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] As Figure 1 , the embodiment of the present invention provides a lubricant pumping device 100, including a sealing chamber 1, an oil barrel 2 and an oil outlet pipe 3. The oil barrel 2 is arranged in the sealing chamber 1, and an air inlet hole 13 is opened on the sealing chamber 1.

[0024] The oil outlet pipe 3 penetrates through the sealing chamber 1, and includes a first indoor pipe section 31 located inside the sealing chamber 1 and a first outdoor pipe section 32 located outside the sealing chamber 1. The first indoor pipe section 31 is inserted into the oil barrel 2, and an oil outlet hole 321 is provided on the first outdoor pipe section 32.

[0025] The above oil barrel 2 is used to store lubricants, which can be grease, lubricating oil, etc.

[0026] Among them, the above air inlet hole 13 is used to connect a pressure air source, including but not limited to compressed air, and an air inlet pipe can be connected at the air inlet hole 13.

[0027] Among them, the above oil outlet hole 321 is used to convey lubricants to the lubrication point, and an oil delivery pipe can be connected at the oil outlet hole 321.

[0028] Based on the above pumping device 100, when air is blown into the sealing chamber 1 through the air inlet hole 13, the pressure in the sealing chamber 1 increases, and the lubricant in the oil barrel 2 is discharged from the oil outlet pipe 3 under the action of pressure, so that the pumping of the lubricant can be realized.

[0029] In one of the embodiments, as Figure 1 , a pressure oil disc 21 is arranged in the oil barrel 2. The pressure oil disc 21 is in piston fit with the inner wall of the oil barrel 2, and the first indoor pipe section 31 passes through the pressure oil disc 21 and is in sliding fit with the pressure oil disc 21.

[0030] Among them, the pressure oil disc 21 is in piston fit with the inner wall of the oil barrel 2. The pressure oil disc 21 is constructed as a piston that can move up and down in the oil barrel 2. There is a clearance fit between the outer ring wall of the pressure oil disc 21 and the inner wall of the oil barrel 2, so that the pressure oil disc 21 can move smoothly and at the same time prevent the lubricant in the oil barrel 2 from overflowing between the pressure oil disc 21 and the inner wall of the oil barrel 2.

[0031] The oil outlet pipe 3 is preferably fixed in position, and the oil pressing disc 21 is in sliding fit with the first indoor pipe section 31. Specifically, the oil pressing disc 21 can slide relative to the first indoor pipe section 31. The oil pressing disc 21 is provided with a first fitting hole, and there is a clearance fit between the hole wall of the first fitting hole and the outer wall of the first indoor pipe section 31, so that the oil pressing disc 21 can move smoothly and at the same time prevent the lubricant in the oil barrel 2 from overflowing between the oil pressing disc 21 and the first indoor pipe section 31.

[0032] By providing the oil pressing disc 21, the oil pumping efficiency can be improved, and the lubricant in the oil barrel 2 can be pumped more fully and waste can be reduced. Moreover, the oil pressing disc 21 also isolates the oil pressing gas from the oil circuit and does not cause the phenomenon of air pressing and blasting.

[0033] When the inner wall of the oil barrel 2 is a tapered inner wall that is wider at the top and narrower at the bottom, the oil pumping efficiency and effect can be improved to a certain extent. Obviously, the outer ring wall structure of the oil pressing disc 21 is designed to match the structure of the inner wall of the oil barrel 2.

[0034] The bottom end of the first indoor pipe section 31 is preferably close to the bottom of the oil barrel 2, which can make the lubricant in the oil barrel 2 be pumped more fully and at the same time avoid the phenomenon of the oil pressing disc 21 separating from the first indoor pipe section 31.

[0035] In one embodiment, the lubricant pumping device 100 further includes a return oil pipe 5. The return oil pipe 5 includes a second indoor pipe section 51 located in the sealing chamber 1 and a second outdoor pipe section 52 located outside the sealing chamber 1. The second indoor pipe section 51 is connected to the second outdoor pipe section 52. The second indoor pipe section 51 is inserted into the oil barrel 2, and the second outdoor pipe section 52 is provided with a return oil hole.

[0036] Among them, the above-mentioned return oil hole is used to receive the return oil from the lubrication point, and a return oil main pipe can be connected at the return oil hole.

[0037] For the case where the oil pressing disc 21 is provided, the second indoor pipe section 51 passes through the oil pressing disc 21 and is in sliding fit with the oil pressing disc 21. Among them, the return oil pipe 5 is preferably fixed in position, and the oil pressing disc 21 is in sliding fit with the second indoor pipe section 51. Specifically, the oil pressing disc 21 can slide relative to the second indoor pipe section 51. The oil pressing disc 21 is provided with a second fitting hole, and there is a clearance fit between the hole wall of the second fitting hole and the outer wall of the second indoor pipe section 51, so that the oil pressing disc 21 can move smoothly and at the same time prevent the lubricant in the oil barrel 2 from overflowing between the oil pressing disc 21 and the second indoor pipe section 51.

[0038] Preferably, as Figure 1, the second indoor pipe section 51 is sleeved outside the first indoor pipe section 31, that is, the first indoor pipe section 31 is at least partially located inside the second indoor pipe section 51. The annular cavity formed by enclosing between the outer wall of the first indoor pipe section 31 and the inner wall of the second indoor pipe section 51 serves as the oil return passage. In this solution, the above-mentioned first mating hole coincides with the second mating hole, that is, only a mating hole that slidably mates with the second indoor pipe section 51 needs to be provided on the pressure oil disk 21, and accordingly, the smoothness and sealing performance of the movement of the pressure oil disk 21 can be improved.

[0039] The second outdoor pipe section 52 and the first outdoor pipe section 32 are relatively independent; optionally, as Figure 1 , the first outdoor pipe section 32 is coaxially connected to the first indoor pipe section 31; optionally, as Figure 1 , the axis of the second outdoor pipe section 52 is perpendicular to the axis of the second indoor pipe section 51.

[0040] The penetration position of the oil outlet pipe 3 in the sealing chamber 1 is preferably sealed to improve the sealing performance of the sealing chamber 1; similarly, the penetration position of the oil return pipe 5 in the sealing chamber 1 is preferably sealed.

[0041] In one embodiment, as Figure 1 , the sealing chamber 1 is also provided with an exhaust hole 14, and the sealing chamber 1 can be exhausted as needed. On the one hand, the exhaust gas in the sealing chamber 1 can be discharged, and on the other hand, the air pressure in the sealing chamber 1 can be flexibly and accurately regulated by means of this exhaust hole 14.

[0042] In one embodiment, the sealing chamber 1 adopts a split detachable splicing structure, so that the sealing chamber 1 can be conveniently opened and closed, facilitating maintenance operations such as replacing the oil barrel 2. As a specific split detachable splicing structure, as Figure 1 , the sealing chamber 1 includes a sealing chamber base 12 and a sealing chamber upper cover 11, and the sealing chamber upper cover 11 is detachably connected to the sealing chamber base 12.

[0043] Among them, the air inlet hole 13 can be provided on the sealing chamber base 12 or on the sealing chamber upper cover 11; the exhaust hole 14 can be provided on the sealing chamber base 12 or on the sealing chamber upper cover 11.

[0044] Preferably, the connection between the sealing chamber upper cover 11 and the sealing chamber base 12 is sealed, including but not limited to measures such as sandwiching a sealing ring between the two.

[0045] Preferably, as Figure 1 , the sealing chamber upper cover 11 is buckled on the sealing chamber base 12. Specifically, the sealing chamber upper cover 11 is sleeved with the sealing chamber base 12, and the sealing chamber upper cover 11 covers the top of the sealing chamber base 12. This method is convenient for forming a high-pressure sealing chamber 1 and also convenient for opening and closing the sealing chamber 1.

[0046] Among them, the upper cover 11 of the sealing chamber can be supported on the surrounding foundation through brackets 6, etc.; optionally, as Figure 1 , brackets 6 are provided on the surrounding foundation. The brackets 6 can be an annular integral bracket arranged around the base 12 of the sealing chamber, or a circle of struts arranged around the base 12 of the sealing chamber. The upper cover 11 of the sealing chamber is supported on the brackets 6 through a plurality of plug connectors. The plurality of plug connectors are arranged at intervals along the circumferential direction of the upper cover 11 of the sealing chamber. The plug connectors can be screws screwed to the upper cover 11 of the sealing chamber / pins pinned to the upper cover 11 of the sealing chamber, etc. In another embodiment, a circle of annular lugs can be provided on the outer wall of the base 12 of the sealing chamber, and the bottom end of the upper cover 11 of the sealing chamber is supported on the annular lugs; or, by adopting the coupling method of the above-mentioned bracket support and lug support, the structural stability of the upper cover 11 of the sealing chamber can be further improved.

[0047] Among them, a sealing ring can be clamped between the inner wall of the upper cover 11 of the sealing chamber and the outer wall of the base 12 of the sealing chamber; for the case where annular lugs are provided on the base 12 of the sealing chamber, a sealing ring can be clamped between the bottom end of the upper cover 11 of the sealing chamber and the annular lugs. The sealing reliability of this sealing method is relatively higher.

[0048] In one embodiment, as Figure 1 , the above-mentioned first outdoor pipe section 32 is also connected with a pneumatic pump 4 for extracting the lubricant in the oil barrel 2. The pneumatic pump 4 includes but is not limited to a pneumatic piston pump. Among them, a piston is provided in the first outdoor pipe section 32, and the piston is connected to the piston of the above-mentioned pneumatic piston pump. By driving the piston to reciprocate in the first outdoor pipe section 32 through the pneumatic piston pump, a vacuum suction force can be formed to suck oil from the oil barrel 2. Based on this scheme, this embodiment has a pressure oil pumping mode (i.e., by blowing air pressure into the sealing chamber 1 to push the lubricant), a pneumatic pump taking mode, and a dual-power pumping mode, with high working flexibility and wide application range, and can meet the pumping requirements of lubricants with different properties (such as viscosity).

[0049] Preferably, the above-mentioned pneumatic pump 4 is configured with an air compressor for supplying compressed air to the pneumatic pump 4.

[0050] In one embodiment, the above-mentioned air compressor includes a machine head and a pressure regulating controller. Among them, the air outlet of the machine head is communicated with the air inlet hole 13 of the sealing chamber 1, and the air outlet hole 14 of the sealing chamber 1 is communicated with the above-mentioned pressure regulating controller.

[0051] In this embodiment, the sealed chamber 1 is used to replace the air storage tank of the air compressor, enabling the sealed chamber 1 to perform the air storage function, greatly reducing the equipment cost. At the same time, maintaining a high-pressure environment inside the sealed chamber 1 can improve the response speed of the pressure oil pumping mode. In particular, the hot compressed gas discharged from the air compressor cylinder is stored in the sealed chamber 1, which can heat and soften the lubricant in the oil barrel 2, making the lubricant have better fluidity and thus being more easily pumped out.

[0052] Optionally, the pressure of the hot compressed gas discharged from the air compressor cylinder is in the range of 0.6 - 0.8 MPa, and the temperature is in the range of 100 - 120 °C. Inside the sealed chamber 1, the pressure of the compressed air is maintained at 0.5 - 0.6 MPa, and the temperature is maintained in the range of 40 - 60 °C.

[0053] Embodiment Two

[0054] As Figure 2 , the embodiment of the present invention provides a lubricant pumping system, including the lubricant pumping device 100 provided in the first embodiment above. The oil outlet hole 321 of the lubricant pumping device 100 is connected to an oil delivery main pipe, and the oil delivery main pipe is connected to a plurality of oil delivery branch pipes 300. Each oil delivery branch pipe 300 is used to connect to different lubrication points.

[0055] In one embodiment, as Figure 2 , a distribution valve 301 is provided at the inlet of each oil delivery branch pipe 300, which can control the oil inlet volume of the branch pipe. Among them, the distribution valve 301 can adopt an electromagnetic valve; more preferably, the distribution valve 301 adopts a rotary valve. The rotary valve core completes the oil path switching during the rotation of the valve core, without the overflow function of the electromagnetic valve. This way can avoid the overflow pollution problem of the distribution valve 301.

[0056] Preferably, a leakage detection mechanism is provided on each oil delivery branch pipe 300, which can improve the operation reliability and safety of the system. In one embodiment, a damping valve is provided at the end of the oil delivery branch pipe 300. Only when the oil pressure in the branch pipe is higher than the set pressure of the damping valve, the lubricant can enter the lubrication point through the damping valve. The above leakage detection mechanism includes a flow detection unit and a pressure detection unit, which can be a flow meter, a pressure gauge, etc. By detecting the flow and pressure in the branch pipe through the flow detection unit and the pressure detection unit, if there is flow but no damping pressure, it indicates that there is a leak in the pipeline.

[0057] Embodiment Three

[0058] The embodiment of the present invention provides an adaptive lubrication method, and the method includes:

[0059] S1, detecting the impurity content U1, moisture content V1, and active ingredient content W1 of the oil discharged from the target lubrication point in the current detection cycle;

[0060] S2. Calculate the period prediction values U2, V2, and W2 of the three parameters for the next detection period based on U1, V1, W1 and the rate of change ΔU, ΔV, and ΔW of these three parameters relative to the previous detection period.

[0061] S3. Determine whether the U2, V2, W2 and the ΔU, ΔV, and ΔW are within the set range.

[0062] When the U2, V2, W2 and the ΔU, ΔV, and ΔW are all within the set range, keep the lubrication period and the single-period lubricant supplement amount of this lubrication point unchanged.

[0063] When the U2, V2, W2 exceed the set threshold, or the ΔU, ΔV, and ΔW exceed the set range, alarm and stop the machine for processing; in this case, it indicates that the value / rate of change of a certain parameter has an abnormal mutation, and an alarm for the deterioration of the lubrication point health is issued, which can facilitate the maintenance personnel to arrange maintenance in a timely manner and avoid sudden shutdowns and other situations.

[0064] In addition to the above two situations, when the period prediction value of any one parameter exceeds the set range, adjust the lubrication system of this lubrication point, where,

[0065] When the first synchronization condition appears, improve lubrication. The improvement of lubrication includes shortening the lubrication period and / or increasing the lubricant supplement amount per period. The first synchronization condition includes: U2 is on the upper deterioration side of the set range of impurity content U, V2 is on the upper deterioration side of the set range of moisture content V, and W2 is on the lower deterioration side of the set range of active ingredient content W.

[0066] When the second synchronization condition appears, weaken lubrication. The weakening of lubrication includes increasing the lubrication period and / or reducing the lubricant supplement amount per period. The second synchronization condition includes: U2 is on the lower deterioration side of the set range of impurity content U, V2 is on the lower deterioration side of the set range of moisture content V, and W2 is on the upper deterioration side of the set range of active ingredient content W; this situation indicates that the lubrication effect is somewhat redundant, and increasing the lubrication period and / or reducing the lubricant supplement amount per period can save lubricant usage and reduce waste.

[0067] When the remaining situations occur, first improve lubrication and output an alarm for the conditions indicating the improvement of lubrication. The conditions indicating the improvement of lubrication include any one of the first synchronization conditions.

[0068] Specifically:

[0069] For the situation where the period prediction values of the three parameters exceed the set range, determine the adjustment direction of the lubrication system represented by each parameter as follows:

[0070] ①U2 is on the deterioration side of the upper limit of the set range of impurity content U (i.e., U2 is greater than the upper limit value of the set range of impurity content U), indicating that lubrication needs to be improved; U2 is on the deterioration side of the lower limit of the set range of impurity content U (i.e., U2 is less than the lower limit value of the set range of impurity content U), indicating that lubrication needs to be weakened.

[0071] ②V2 is on the deterioration side of the upper limit of the set range of moisture content V (i.e., V2 is greater than the upper limit value of the set range of moisture content V), indicating that lubrication needs to be improved; V2 is on the deterioration side of the lower limit of the set range of moisture content V (i.e., V2 is less than the lower limit value of the set range of moisture content V), indicating that lubrication needs to be weakened.

[0072] ③W2 is on the deterioration side of the lower limit of the set range of active ingredient content W (i.e., W2 is less than the lower limit value of the set range of active ingredient content W), indicating that lubrication needs to be improved; W2 is on the deterioration side of the upper limit of the set range of active ingredient content W (i.e., W2 is greater than the upper limit value of the set range of active ingredient content W), indicating that lubrication needs to be weakened.

[0073] Thus, when the lubrication system adjustment directions characterized by U2, V2, and W2 are all the same (improve lubrication / weaken lubrication), lubrication adjustment is carried out according to the characterized lubrication system adjustment direction.

[0074] When the lubrication system adjustment directions characterized by U2, V2, and W2 are not the same, that is, some parameters indicate that lubrication needs to be improved and some parameters indicate that lubrication needs to be weakened. In this case, improving lubrication first can ensure the safety of the lubrication point. At the same time, outputting an alarm for the conditions indicating improved lubrication can timely detect and eliminate abnormal emergencies, etc., and improve the working reliability of the lubrication point.

[0075] Based on the above method, through oil product detection, based on the numerical values and change rate detection of the three parameters of impurity content, moisture content, and active ingredient content of the drained oil at the lubrication point, the lubrication cycle and the single-cycle lubricant replenishment amount of the lubrication point are adjusted in a matching manner, so as to realize the adaptive adjustment of the lubrication system of the lubrication point, improve the rationality of the lubrication system, effectively improve the working reliability of the lubrication point, and can timely judge the health status of the lubrication point, so that maintenance can be planned, sudden failures can be avoided, and the equipment life of the lubrication point can be extended.

[0076] Among them, the detection of the three parameters U, V, and W can be carried out online at the oil drain port of the lubrication point.

[0077] In the above method, the detection of the three parameters U, V, and W is performed periodically; preferably, the detection period corresponds one-to-one with the lubrication period. For example, when oil is drained from the oil drain port (i.e., when oil is replenished at the oil replenishment port) in each lubrication period, the three parameters U, V, and W are detected. When determining whether the period prediction values of the three parameters in the next detection period are within the set range, that is, when determining whether the period prediction values of the three parameters are within the set range at the beginning of the next lubrication period, the lubrication regime of the lubrication point can be adjusted more reliably in this way.

[0078] In one embodiment, when calculating the period prediction values of the three parameters in the next detection period, based on the numerical change rates of the three parameters, the calculation is performed on the condition that the numerical changes of each parameter are linear changes. For example, U2 = U1 + ΔU * t, where t is the detection period. This method can relatively accurately and conveniently obtain the period prediction values of each parameter; in other embodiments, when calculating the period prediction values of the three parameters in the next detection period, a change curve of each parameter is generated by fitting based on the historical numerical change rates of each parameter (including but not limited to using the linear regression fitting method), and the period prediction value of the parameter is obtained based on the change curve of the parameter.

[0079] In addition, for the bearings of each lubrication point, the change rules of the loss and failure of the lubrication point bearings under different loads, different temperature environments, different dust environments, different types of lubricants, etc. can be recorded for a long time to form a relevant database, which is convenient for setting a reasonable lubrication regime for the lubrication of such bearings on other devices, so as to quickly establish a reasonable lubrication regime.

[0080] Correspondingly, an embodiment of the present invention further provides an adaptive lubrication controller 200, including:

[0081] A processor;

[0082] A memory communicatively connected to the processor, the memory storing adaptive lubrication instructions that can be run on the processor, and the adaptive lubrication instructions being configured to implement the above-mentioned adaptive lubrication method.

[0083] Preferably, the adaptive lubrication controller 200 in this embodiment can be applied to the second embodiment above, that is, configured into the above-mentioned lubricant pumping system. Among them, the lubricant pumping device 100, the distribution valve 301, etc. are all electrically connected or communicatively connected to the above-mentioned processor. After the processor obtains the adaptive lubrication instructions, it controls the lubricant pumping device 100, the distribution valve 301, etc. to work in a matching manner.

[0084] For the electrical connection or communication connection between the lubricant pumping device 100 and the processor, it specifically includes the connection between the air-blowing device (for blowing air into the air inlet hole 13) and the processor, the connection between the pneumatic pump 4 and the processor, etc.

The waste oil collection pipe / waste oil collection tank can slope from the oil drain hole to the waste oil collection device 400 to facilitate the flow of grease.
