[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0019] Please also read Figures 1 to 9 , now the integrated device for testing the pressure and flow of a lubricating pump provided by the present invention is described. The integrated device for testing the pressure and flow of a lubricating pump comprises a support platform 1, a mounting frame 2, a test pipe 3 and a lubricant barrel 4; the mounting frame 2 is arranged on the support platform 1; the mounting frame 2 is used to fix the lubricating pump 5; the test pipe 3 is connected to the support platform 1 through a support frame 31; the test pipe 3 is provided with a pressure gauge (not shown in the figure) and a flow meter (not shown in the figure); one end of the test pipe 3 is used to be installed on the oil outlet 52 of the lubricating pump 5; the lubricating barrel 4 comprises a barrel body 41 and a cover body 42; the cover body 42 is detachably connected to the barrel body 41, and the cover body 42 is provided with an oil outlet joint 43, which is used to communicate with the oil suction port on the lubricating pump 5; the barrel body 41 is provided with a balancing structure for balancing the air pressure; wherein, there are two lubricating barrels 4, one of which is used to be installed on the lubricating pump 5, and the other lubricating barrel 4 is used to collect the lubricant discharged from the test pipe 3. A quick connector is provided at the oil outlet 52 of the lubrication pump 5, and one end of the test pipe 3 is connected to the quick connector.
[0020] The invention provides an integrated device for testing the pressure and flow of a lubricating pump 5. Compared with the prior art, the lubricating pump 5 is installed on a mounting frame 2, and one end of a testing pipeline 3 is connected to an oil outlet 52 of the lubricating pump 5; the lubricant barrel 4 can be installed on the lubricating pump 5 by fixing a cover body 42 on a barrel body 41 and providing an oil outlet joint 43 on the cover body 42; when the lubricating pump 5 is started, the lubricant in the barrel body 41 can be drawn out and discharged from the oil outlet 52; the discharged lubricant enters the testing pipeline 3, and the pressure gauge and flow meter on the testing pipeline 3 can be used to know the pressure of the lubricating pump 5. pressure and flow; the lubricant discharged from the test pipe 3 flows into the barrel body 41 of another lubricant barrel 4 to collect the discharged lubricant; when the lubricant barrel 4 at the collection position collects to the preset liquid level, the lubricant barrel 4 installed on the lubrication pump 5 is used up, and the two lubricant barrels 4 swap positions at this time; through the above-mentioned arrangement of the present application, when the lubricant barrel 4 at the collection position collects to the preset liquid level, the cover body 42 is fixed on the barrel body 41, and the lubricant barrel 4 can be directly installed on the lubrication pump 5 for use, without the need to inject the lubricant in the lubricant barrel 4 into other containers, which can improve operating efficiency.
[0021] Exemplarily, the mounting frame 2 has a mounting hole, the lubrication pump 5 has a mounting base 51, and the mounting base 51 has a through hole aligned with the mounting hole; when the through hole on the mounting base 51 is aligned with the mounting hole on the mounting frame 2, the mounting base 51 and the mounting frame 2 are plugged together through the pin 11; the mounting frame 2 also has a support seat 21 for supporting the motor of the lubrication pump 5. When the lubrication pump 5 is placed on the mounting frame 2, the support seat 21 can provide support for the motor on the lubrication pump 5, and when the through hole on the mounting base 51 is aligned with the mounting hole on the mounting frame 2, the lubrication pump 5 can be positioned through the pin 11 plugged together with the mounting base 51 and the mounting frame 2; the mounting frame 2 is fixed on the support platform 1, and the support seat 21 is fixed on the mounting frame 2.
[0022] It should be noted that there are multiple mounting holes on the mounting frame 2, and the number of through holes on the mounting base 51 is the same as the number of mounting holes, and corresponds one to one; by setting multiple mounting holes, the accuracy of positioning the lubrication pump 5 can be improved, and during the test process, the horizontal movement of the lubrication pump 5 can be reduced.
[0023] In some embodiments, Figures 1 to 9 As shown, the balancing structure includes a one-way valve 44, which is arranged at the bottom of the barrel body 41; the conducting direction of the one-way valve 44 is from the outside of the barrel body 41 to the inside of the barrel body 41; wherein, when the lubricant barrel 4 is installed on the lubrication pump 5, the cover body 42 is fixed on the barrel body 41, and the oil outlet joint 43 on the cover body 42 is connected to the oil suction port on the lubrication pump 5.
[0024] It should be noted that, by providing a one-way valve 44 on the bottom wall of the barrel body 41, and the conducting direction of the one-way valve 44 is from the outside of the barrel body 41 to the inside of the barrel body 41, when the barrel body 41 is used to collect lubricants, the one-way valve 44 is always in a closed state, which can prevent the lubricant from being discharged from the one-way valve 44. When the barrel body 41 is installed on the lubrication pump 5, the one-way valve 44 is located at the top of the barrel body 41; as the lubricant in the barrel body 41 decreases, the air pressure in the barrel body 41 will decrease, and at this time, the external air can open the one-way valve 44 and enter the barrel body 41 to balance the air pressure inside and outside the barrel body 41, so that the lubrication pump 5 can extract the lubricant in the barrel body 41.
[0025] Exemplarily, when the lubricant barrel 4 is installed on the lubrication pump 5, a pressure plate 6 can be set on the support platform 1 and placed at the top position of the lubricant barrel 4; the pressure plate 6 avoids the position of the one-way valve 44, and the pressure plate 6 is connected to the support platform 1 through a screw 61; specifically, the screw 61 is rotatably set on the support platform 1, and in the height direction, the screw 61 and the support platform 1 are relatively fixed; the pressure plate 6 has a threaded hole that matches the thread of the screw 61; after the lubricant barrel 4 is installed on the lubrication pump 5, the pressure plate 6 is rotated to the top of the lubricant barrel 4, and then the screw 61 is rotated to make the pressure plate 6 press the lubricant barrel 4; through the above arrangement, the connection between the lubricant barrel 4 and the lubrication pump 5 can be guaranteed.
[0026] Exemplarily, a transverse plate 62 is fixed on the mounting frame 2, and the transverse plate 62 has a through hole for the screw 61 to pass through; the screw 61 is respectively fixed with positioning rings 63 on the upper and lower sides of the transverse plate 62, and the two positioning rings 63 are respectively in contact with the top and bottom of the transverse plate 62 to limit the position of the screw 61 in the height direction; through the above arrangement, the screw 61 can rotate around its own axis, and the screw 61 will not move in the height direction.
[0027] In addition, the lubricant barrel 4 filled with lubricant can be used to test multiple lubricating pumps 5 , and it is not necessary for one lubricating pump 5 to use up all the lubricant in the lubricant barrel 4 .
[0028] In some embodiments, Figures 1 to 9 As shown, the balancing structure also includes a sealing plate 45, which is arranged in the barrel body 41; the outer peripheral wall of the sealing plate 45 is sealed with the inner peripheral wall of the barrel body 41, and the sealing plate 45 can slide in the barrel body 41; wherein, the inside of the side wall of the barrel body 41 has a balancing air channel 411, and the balancing air channel 411 is connected to the open end of the barrel body 41; the inner peripheral wall of the barrel body 41 has an air outlet 412 connected to the balancing air channel 411 near the bottom, or the bottom wall inside the barrel body 41 has an air outlet 412 connected to the balancing air channel 411.
[0029] It should be noted that, by setting a sealing plate 45 in the barrel body 41, when the barrel body 41 collects lubricant, the lubricant is located between the top of the sealing plate 45 and the top of the barrel body 41, so the lubricant will not flow into the position of the one-way valve 44; when the barrel body 41 needs to collect lubricating oil, the cover body 42 is separated from the barrel body 41, and at this time the balancing air channel 411 is connected to the outside; the sealing plate 45 is slid to the bottom position of the barrel body 41, and during the sliding process of the sealing plate 45, the air between the bottom of the sealing plate 45 and the bottom of the barrel body 41 is discharged from the air outlet 412 and the balancing air channel 411, so that the sealing plate 45 can slide smoothly to the bottom of the barrel body 41.
[0030] When the lubricant barrel 4 is installed on the lubrication pump 5, the cover body 42 is fixed on the barrel body 41, and the cover body 42 closes the open end of the barrel body 41. At this time, the balance air passage 411 cannot be connected to the outside through the open end of the barrel body 41; during the test, the lubricant in the barrel body 41 will decrease, and the air pressure in the barrel body 41 will decrease; at this time, the air pressure in the barrel body 41 can be balanced through the one-way valve 44.
[0031] In some embodiments, Figures 1 to 9 As shown, when the air outlet 412 is located on the inner circumferential wall of the barrel body 41 , the distance between the air outlet 412 and the bottom wall of the barrel body 41 is less than the thickness of the sealing plate 45 .
[0032] It should be noted that when the opening end of the barrel body 41 is facing upward, when the sealing plate 45 slides to the bottom position of the barrel body 41, the air outlet 412 is located at the outer peripheral wall of the sealing plate 45; through the above arrangement, the barrel body 41 can reduce the lubricant from entering the air outlet 412 during the process of collecting the lubricant, thereby reducing the waste of lubricant.
[0033] In some embodiments, Figures 1 to 9 As shown, the balancing structure also includes a sleeve 46 and a sealing plate 45; the sleeve 46 is sleeved in the barrel body 41; the outer peripheral wall of the sleeve 46 is connected with a plurality of ribs 47 along the circumferential direction, and each rib 47 is arranged along the axial direction of the sleeve 46; the sealing plate 45 is slidably arranged in the sleeve 46; the outer peripheral wall of the sealing plate 45 is sealed with the inner peripheral wall of the sleeve 46; wherein, the bottom end of the rib 47 of the sealing plate 45 protrudes from the bottom end of the sleeve 46, and the length of the protruding part of the rib 47 is less than the thickness of the sealing plate 45; when the cover body 42 is connected to the barrel body 41, the cover body 42 closes the gap between the sleeve 46 and the barrel body 41.
[0034] It should be noted that the rib 47 is fixed on the outer circumferential wall of the sleeve 46, and the rib 47 is in contact with the inner circumferential wall of the barrel body 41; by arranging the rib 47 between the sleeve 46 and the barrel body 41, an air passage 461 can be formed between the sleeve 46 and the barrel body 41; since the rib 47 has a protruding portion 471, when the sleeve 46 and the rib 47 are installed in place, there is a gap between the protruding portion 471 of the rib 47 and the bottom end of the sleeve 46, so that the space between the sealing plate 45 and the bottom wall of the barrel body 41 can be connected to the air passage 461; since the length of the protruding portion 471 of the rib 47 is less than the thickness of the sealing plate 45, when the sealing plate 45 slides to the bottom position of the barrel body 41, the protruding portion 471 of the rib 47 is located below the top of the sealing plate 45, so when collecting the lubricant, the lubricant will not flow into the protruding portion 471 of the rib 47, nor will it flow into the air passage 461.
[0035] In some embodiments, Figures 1 to 9 As shown, the inner wall of the barrel body 41 has an internal thread near the bottom, and the protruding portion 471 of the rib plate 47 has an external thread that matches the internal thread.
[0036] It should be noted that when the sleeve 46 is installed in the barrel body 41, the external thread of the protruding part 471 of the rib 47 can cooperate with the internal thread of the inner circumferential wall of the barrel body 41 close to the bottom wall, thereby fixing the sleeve 46 in the barrel body 41; since the outer circumferential wall of the protruding part 471 of the rib 47 is not a complete circle, the outer circumferential wall of the protruding part 471 of the rib 47 only has a part of the external thread, and the protruding part 471 of each rib 47 has a part of the external thread, which will not affect the threaded cooperation between the rib 47 and the barrel body 41.
[0037] In some embodiments, Figures 1 to 9 As shown, the inner wall of the barrel body 41 near the top has an internal thread, the cover body 42 has an inserting portion 421 for inserting into the barrel body 41, the inserting portion 421 has an external thread, and the inserting portion 421 is threadedly matched with the barrel body 41.
[0038] It should be noted that the cover body 42 can be fixed on the barrel body 41 through the threaded cooperation between the plug-in portion 421 and the inner wall of the barrel body 41; when the balancing air duct 411 is located inside the side wall of the barrel body 41, the cover body 42 can close the open end of the barrel body 41 through the threaded cooperation between the plug-in portion 421 and the barrel body 41, so that the balancing air duct 411 cannot be connected to the outside through the open end of the barrel body 41.
[0039] When the sleeve 46 is set in the barrel body 41, the height of the sleeve 46 is lower than the height of the barrel body 41, so it can provide space for the threaded cooperation between the plug-in part 421 and the barrel body 41; since the protruding part 471 of the rib 47 is also provided with an external thread, when the sleeve 46 is placed into the barrel body 41, the protruding part 471 of the rib 47 will first be threadedly engaged with the position near the top of the barrel body 41, and then when the rib 47 slides to the bottom wall position, it will be threadedly engaged with the bottom position of the barrel body 41.
[0040] In some embodiments, Figures 1 to 9 As shown, the support platform 1 has a fixing frame 12 at the outlet of the test pipe 3 , the fixing frame 12 has a slot 121 for plugging with the lubricant barrel 4 , and the bottom wall of the slot 121 has an avoidance hole 122 for avoiding the one-way valve 44 .
[0041] It should be noted that, by setting a fixing frame 12 on the supporting platform 1, the barrel body 41 of the lubricant barrel 4 can be placed into the slot 121 of the fixing frame 12, and the stability of the barrel body 41 can be ensured during the process of collecting the lubricant; by setting an avoidance hole 122 on the bottom wall of the slot 121, the one-way valve 44 can be placed into the avoidance hole 122, thereby ensuring that the barrel body 41 is stably placed on the fixing frame 12.
[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
