Description

Technical Field

[0001] This application relates to the field of lubrication pumping systems, and in particular to an oil circuit throttling device for a multi-point oil outlet lubrication pumping system. Background Technology

[0002] A lubrication system refers to a series of devices for supplying and discharging lubricant to lubrication points, along with their auxiliary components. Lubrication systems can be classified into five types: circulating lubrication systems, centralized lubrication systems, spray lubrication systems, oil-immersion and splash lubrication systems, and total-loss lubrication systems using oil and grease.

[0003] During use, a lubrication system typically needs to supply lubricating oil to multiple lubrication points simultaneously. Therefore, a lubrication system usually includes an oil distribution system to distribute lubricating oil to different lubrication points.

[0004] However, since the flow rate of the oil distribution system cannot be controlled, and as lubricating oil is continuously supplied to the lubrication points, the required amount of lubricating oil will be quickly met. If the flow rate is not controlled, it is easy to cause waste or oversupply. Summary of the Invention

[0005] In order to improve the problem that the flow rate of the oil distribution system cannot be controlled, and that the lubrication required by the lubrication parts will be quickly met as lubrication oil is continuously supplied, if the flow rate is not controlled, it is easy to cause waste or oversupply, this application provides an oil circuit throttling device for a multi-point oil outlet lubrication pumping system.

[0006] The oil circuit throttling device for a multi-point oil outlet lubrication pumping system provided in this application adopts the following technical solution:

[0007] A throttling device for a multi-point oil lubrication pumping system includes: an oil supply assembly and multiple oil outlet pipes, wherein a throttling assembly is provided between the oil supply assembly and the multiple oil outlet pipes;

[0008] The throttling component includes an oil inlet, which includes a fixed block and a glass cover. The glass cover is fixed to the fixed block, and an oil inlet cavity is formed between the glass cover and the fixed block. The oil supply component communicates with the oil inlet cavity. The side wall of the fixed block has multiple oil outlet holes, which are evenly arranged circumferentially and communicate with the oil inlet cavity. The oil outlet pipe is detachably connected to the fixed block and communicates with the oil outlet holes.

[0009] By adopting the above technical solution, the lubricating oil at the oil supply component can be delivered to the oil outlet pipe, and then delivered to the lubrication part by the oil outlet pipe; and during the oil supply process, the flow rate in the oil outlet pipe can be adjusted by the throttling component, so as not to waste or oversupply the lubricating oil.

[0010] Optionally, the throttling assembly further includes: a main throttling section, which includes: a rotating rod, a rotating plate, and multiple adjusting plates. The rotating plate is mounted on the fixed block, and the multiple oil outlet holes are evenly arranged along the circumference of the rotating plate. The adjusting plates are evenly arranged on the rotating plate along the circumference of the rotating plate, and the adjusting plates cover the oil outlet holes. One end of the rotating rod is fixed to the rotating plate, and the other end passes through the glass cover.

[0011] By adopting the above technical solution, the flow rate of the oil outlet can be adjusted by using the degree of coverage of the oil outlet by the adjusting plate, so as to avoid waste or oversupply; and the flow rates of multiple oil outlets can be adjusted synchronously.

[0012] Optionally, the throttling assembly further includes a fixing part, which includes a fixing plate and a fixing bolt. The fixing plate is fixed to the glass cover, and a clearance hole is formed through the fixing plate. A fixing groove is formed on the fixing plate and communicates with the clearance hole. The rotating rod passes through the clearance hole and has a fixing hole. The fixing bolt passes through the fixing groove and is threaded into the fixing hole.

[0013] By adopting the above technical solution, after the adjustment plate is adjusted, the rotating rod can be locked, so that the rotating rod is not easy to change the degree of coverage of the oil outlet due to its own rotation.

[0014] Optionally, the throttling assembly further includes: a throttling section, wherein a through hole is provided on the adjusting plate and the through hole communicates with the oil outlet hole, and a receiving groove is provided on the inner wall of the through hole; the throttling section includes: a sealing plate and a screw, wherein one end of the sealing plate is slidably connected to the receiving groove and has a threaded hole, and the other end closes the through hole; one end of the screw is rotatably installed in the receiving groove, and the other end is threadedly connected to the threaded hole.

[0015] By adopting the above technical solution, the flow rate of a single oil outlet can be adjusted independently by changing the degree of closure of the sealing plate over the connecting hole, without the need for simultaneous adjustment of multiple oil outlets, thereby improving applicability.

[0016] Optionally, the throttling assembly further includes: a connecting part, wherein the rotating plate has a cavity inside, and the end of the screw away from the sealing plate extends into the cavity; the connecting part includes: a miniature electric push rod and a connecting rod, wherein the miniature electric push rod is fixedly installed on the end of the screw, and the connecting rod is fixed to the push shaft of the miniature electric push rod.

[0017] By adopting the above technical solution, the connecting rod and the miniature electric push rod play a transitional role. Once the connecting rod and the miniature electric push rod rotate, the screw can rotate, thereby driving the sealing plate to slide, so as to change the degree of closure of the connecting hole.

[0018] Optionally, the throttling assembly further includes a driving part, wherein the rotating rod has a through hole that extends to the rotating plate and communicates with the cavity, the driving part includes a driving rod, a driving gear and a driven gear, the driving rod is rotatably mounted in the through hole and one end extends into the cavity, the driving gear is coaxially fixed with the driving rod, and the driven gear is coaxially fixed with the connecting rod.

[0019] By adopting the above technical solution, the operator can drive the screw to rotate, thereby driving the sealing plate to slide and changing the degree of closure of the connecting hole.

[0020] Optionally, the throttling assembly further includes a marking part, which includes a first colored bar and a second colored bar, wherein the first colored bar is fixed to the drive rod and the second colored bar is fixed to the end of the rotating rod.

[0021] By adopting the above technical solution, when the drive rod rotates to the position where the first colored bar corresponds to the second colored bar, the driving gear can smoothly mesh with the driven gear, thereby improving the adjustment efficiency.

[0022] Optionally, the glass cover is provided with a sealing groove, and the total throttling part further includes a rubber ring, which is fixedly sleeved on the rotating rod and is interference-fitted into the sealing groove.

[0023] By adopting the above technical solution, the rubber ring can improve the sealing between the rotating rod and the glass cover, thus making it less likely for lubricating oil to leak.

[0024] Optionally, the total throttling section further includes a rubber pad, which is fixed to the adjusting plate and abuts against the fixing block.

[0025] By adopting the above technical solution, the rubber pad can improve the sealing between the adjusting plate and the fixed block when the adjusting plate completely covers the oil outlet.

[0026] Optionally, the throttling section further includes a rubber sleeve, which is fixedly fitted onto the sealing plate.

[0027] By adopting the above technical solution, the rubber sleeve can improve the sealing performance between the sealing plate and the inner wall of the connecting hole, as well as the sealing performance between the sealing plate and the inner wall of the receiving groove.

[0028] In summary, this application includes at least one of the following beneficial effects:

[0029] 1. The lubricating oil at the oil supply component can be delivered to the oil outlet pipe, and then from the oil outlet pipe to the lubrication point; and during the oil supply process, the flow rate in the oil outlet pipe can be adjusted by the throttling component, so as not to waste or oversupply the lubricating oil.

[0030] 2. The flow rate of a single oil outlet can be adjusted independently by changing the degree of closure of the sealing plate over the connecting hole, without the need for simultaneous adjustment of multiple oil outlets, thus improving applicability.

[0031] 3. The rubber ring can improve the sealing between the rotating rod and the glass cover, thus making it less likely for lubricating oil to leak. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0038] This application discloses an oil circuit throttling device for a multi-point oil outlet lubrication pumping system. (Refer to...) Figure 1A multi-point oil outlet lubrication pumping system oil circuit throttling device includes an oil supply assembly 1 and multiple oil outlet pipes 2. In this embodiment, there are four oil outlet pipes 2. A throttling assembly 3 is provided between the oil supply assembly 1 and the oil outlet pipes 2. The oil supply assembly 1 includes an oil reservoir 11, a connecting pipe 12, an oil inlet pipe 13, and a plunger pump 14. The oil reservoir 11 is used to store lubricating oil, and when it is insufficient, lubricating oil can be delivered into the oil reservoir 11. One end of the connecting pipe 12 is connected to the oil reservoir 11, and the other end is connected to the plunger pump 14. One end of the oil inlet pipe 13 is connected to the plunger pump 14, and the other end is connected to the throttling assembly 3.

[0039] When supplying oil, first connect the lubrication part that needs to be lubricated to the oil outlet pipe 2, then start the plunger pump 14. At this time, the lubricating oil in the storage tank is transported from the connecting pipe 12 to the oil inlet pipe 13, then from the oil inlet pipe 13 to the throttling component 3, and finally from the oil outlet pipe 2 to the lubrication part to lubricate it. During this process, the flow rate can be adjusted using the throttling component 3. In particular, when the amount of lubricating oil used is close to the demand, the flow rate can be reduced using the throttling component 3, so as to avoid waste or oversupply.

[0040] Reference Figure 2 , Figure 3 and Figure 4 The throttling assembly 3 includes: an oil inlet 4, a main throttling section 5, a fixing section 6, a branch throttling section 7, a connecting section 8, a driving section 9, and a marking section 10.

[0041] Reference Figure 2 The oil inlet 4 includes a fixing block 41 and a glass cover 42. The glass cover 42 is fixed on the fixing block 41, and an oil inlet cavity 421 is formed between the glass cover 42 and the fixing block 41. Since the glass cover 42 has transparent properties, it is convenient for subsequent personnel to adjust the main throttling section 5 and the sub-throttling section 7.

[0042] The end of the oil inlet pipe 13 away from the plunger pump 14 is connected to the oil inlet chamber 421. Multiple oil outlet holes 411 are provided through the side of the fixing block 41 away from the glass cover 42. In this embodiment, four oil outlet holes 411 are provided, and each of the four oil outlet holes 411 corresponds one-to-one with a one-to-one correspondence with an oil outlet pipe 2. The four oil outlet holes 411 are evenly arranged circumferentially. The oil outlet pipe 2 is detachably fixed to the side of the fixing block 41 away from the glass cover 42 by bolts, and the oil outlet pipe 2 is connected to the oil outlet holes 411.

[0043] Reference Figure 3 and Figure 4The main throttling section 5 includes: a rotating rod 51, a rotating plate 52, a rubber ring 54, a rubber pad 55, and multiple adjusting plates 53. The rotating plate 52 is installed on the side of the fixed block 41 near the glass cover 42, that is, located in the oil inlet chamber 421. The oil outlet holes 411 are evenly arranged along the circumference of the rotating plate 52. In this embodiment, there are four adjusting plates 53, and the four adjusting plates 53 correspond one-to-one with the four oil outlet holes 411. The four adjusting plates 53 are evenly arranged along the circumference of the rotating plate 52 on the side wall of the rotating plate 52, and the adjusting plates 53 cover the oil outlet holes 411. In this embodiment, the adjusting plates 53 and the rotating plate 52 are integrally formed.

[0044] One end of the rotating rod 51 is fixed to the side of the rotating plate 52 away from the fixed block 41, and the other end passes through the side of the glass cover 42 away from the fixed block 41. The rotating rod 51 can drive the rotating plate 52 to rotate. When supplying oil, the operator can hold the rotating rod 51 and rotate it to drive the rotating plate 52 to rotate, thereby the adjusting plate 53 also rotates to synchronously adjust the degree of coverage of the four adjusting plates 53 on the oil outlet 411. If the degree of coverage is large, the flow rate decreases; if the degree of coverage is small, the flow rate increases.

[0045] Furthermore, a sealing groove 422 is formed on the inner wall of the glass cover 42 along the circumference of the rotating rod 51. The rubber ring 54 is fixedly sleeved on the rotating rod 51 and is interference-fitted into the sealing groove 422. The rubber pad 55 is fixed to the side of the adjusting plate 53 near the fixing block 41 and abuts against the side wall of the fixing block 41. In this embodiment, the rubber ring 54 and the rubber pad 55 do not affect the rotation of the rotating rod 51 and the rotating plate 52.

[0046] Reference Figure 3 The fixing part 6 includes a fixing plate 61 and a fixing bolt 62. The fixing plate 61 is fixed to the side of the glass cover 42 away from the fixing block 41, and a clearance hole 611 is provided through the side wall of the fixing plate 61. The end of the rotating rod 51 away from the rotating plate 52 passes through the clearance hole 611. A fixing groove 612 is provided on the peripheral wall of the fixing plate 61. The fixing groove 612 is connected to the clearance hole 611, and the angle of the fixing groove 612 satisfies two states: the adjusting plate 53 is fully open of the oil outlet hole 411 and fully covered by the oil outlet hole 411.

[0047] The rotating rod 51 has a fixing hole 511 on its side wall, and the fixing hole 511 communicates with the fixing groove 612. The rod of the fixing bolt 62 passes through the fixing groove 612 and is threaded into the fixing hole 511, and the nut of the fixing bolt 62 abuts against the fixing plate 61. After the adjusting plate 53 is adjusted, the fixing bolt 62 can be used to fix the rotating rod 51.

[0048] Reference Figure 4The side wall of the adjusting plate 53 has a through-hole 531, which is connected to the oil outlet 411. In this embodiment, the through-hole 531 is a square hole, and its size is much larger than that of the oil outlet 411. A square receiving groove 532 is formed on the inner wall of the through-hole 531 near the rotating plate 52. The throttling part 7 includes a sealing plate 71, a rubber sleeve 73, and a screw 72. One end of the sealing plate 71 is slidably connected to the receiving groove 532, and the other end closes the through-hole 531. A threaded hole 711 is formed on the side of the sealing plate 71 near the bottom of the receiving groove 532. One end of the screw 72 is rotatably installed in the receiving groove 532, and the other end is threadedly connected to the threaded hole 711.

[0049] In addition, the rubber sleeve 73 is fixedly sleeved on the sealing plate 71, and the rubber sleeve 73 abuts against the inner wall of the connecting hole 531.

[0050] Reference Figure 4 The rotating plate 52 has a circular cavity 521 inside, and the end of the screw 72 away from the sealing plate 71 extends into the cavity 521. The connecting part 8 includes a miniature electric push rod 81 and a connecting rod 82. The miniature electric push rod 81 is fixed to the end of the screw 72 located in the cavity 521. The connecting rod 82 is fixed to the push shaft of the miniature electric push rod 81.

[0051] Reference Figure 4 The rotating rod 51 has a through hole 512 extending through its own axis at the end away from the rotating plate 52, and the through hole 512 extends onto the rotating plate 52 and communicates with the cavity 521. The driving unit 9 includes a driving rod 91, a driving gear 92, and a driven gear 93. The driving rod 91 is rotatably mounted in the through hole 512, with one end extending out of the through hole 512 and the other end extending into the cavity 521. The end of the driving rod 91 located in the cavity 521 is coaxially fixed with the driving gear 92. The end of the connecting rod 82 away from the micro electric push rod 81 is coaxially fixed with the driven gear 93.

[0052] If each oil outlet pipe 2 requires a different flow rate, the micro electric push rod 81 corresponding to a single oil outlet pipe 2 can be activated to push the driven gear 93 closer to the driving gear 92 until the driven gear 93 meshes with the driving gear 92; then the drive rod 91 is rotated, and the rotation of the drive rod 91 will sequentially drive the rotation of the driving gear 92, the driven gear 93, the connecting rod 82, the micro electric push rod 81 and the screw 72, so that the sealing plate 71 will retract into the receiving groove 532 to open the connecting hole 531 to different degrees, thereby completing the flow rate adjustment; after adjustment, the micro electric push rod 81 can be activated to pull back the connecting rod 82, thereby separating the driven gear 93 from the driving gear 92, and the above operation can be repeated for the flow rate adjustment of the remaining oil outlet pipes 2. The reason why the screw 72 is used instead of the miniature electric push rod 81 to directly push the sealing plate 71 in this embodiment is that once a little lubricating oil leaks into the receiving groove 532, the screw 72 is not easily damaged, and the screw 72 can also be lubricated to extend its service life; if the miniature electric push rod 81 is used, it is easy to be damaged.

[0053] In this embodiment, the flow rates of multiple oil outlet pipes 2 can be adjusted simultaneously, or the flow rate of each oil outlet pipe 2 can be adjusted individually, and it is a separate throttling device.

[0054] Reference Figure 3 The marking section 10 includes a first colored bar 101 and a second colored bar 102. The first colored bar 101 is fixed to the side wall of the drive rod 91 away from the cavity 521 and is horizontally arranged. The second colored bar 102 is fixed to the end of the rotating rod 51 away from the rotating plate 52 and is horizontally arranged. When the driven gear 93 needs to mesh with the driving gear 92, the drive rod 91 is first rotated until the first colored bar 101 and the second colored bar 102 are in the same horizontal plane, thereby facilitating the meshing of the driven gear 93 and the driving gear 92.

[0055] The implementation principle of the oil circuit throttling device of the multi-point oil lubrication pumping system in this application embodiment is as follows: When supplying oil, the operator can hold the rotating rod 51 and rotate the rotating rod 51 to drive the rotating plate 52 to rotate, thereby the adjusting plate 53 also rotates accordingly, so as to synchronously adjust the degree of coverage of the oil outlet 411 by the four adjusting plates 53. If the degree of coverage is large, the flow rate decreases; if the degree of coverage is small, the flow rate increases.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
