Description

Technical Field

[0001] The present application relates to the technical field of compressor oil injection systems, and in particular to a redundant system for forced oil injection of compressors. Background Art

[0002] The stable operation of a compressor unit's forced oil injection system is crucial during production. It ensures adequate lubrication of all compressor components to reduce wear, improve operating efficiency, and extend equipment life. This system typically includes an oil injection pump, distributor, lubricating oil tank, electronic monitoring components (such as a no-oil flow switch), and corresponding piping and valves. However, no-oil flow alarms frequently occur during compressor operation, causing unit shutdowns and seriously impacting stable operation. Therefore, the problem of compressor unit shutdowns caused by no-oil flow alarms has become a pressing issue that needs to be addressed. Summary of the Invention

[0003] In order to improve the problem that the current compressor unit is prone to shutdown due to oil flow alarm during production movement, the present application provides a compressor forced oil injection redundant system, including a lubricating oil tank, an oil injection pump, and a main distributor. The oil injection pump is installed to the lubricating oil tank, and a liquid inlet and several liquid outlets are provided on the main distributor. An oil injection pipe is provided between the liquid inlet and the oil injection pump, and an oil distribution pipe is provided at the liquid outlet. The oil distribution pipe is used to connect with the lubrication channels of various components of the compressor, and also includes a redundant system. The redundant system includes a sub-distributor, an oil inlet hole and several oil discharge holes are provided on the sub-distributor, a sub-pipe is provided between the oil inlet hole and the oil injection pipe, and a sub-branch pipe is provided at the oil discharge hole. Several of the sub-branch pipes correspond one to one with and are connected to several of the oil distribution pipes.

[0004] By adopting the above solution and setting up a redundant system, when the main distributor fails, the secondary distributor can continue to keep the entire oil injection system unobstructed, reducing the number of unit failure shutdowns and improving the unit's operating rate. Furthermore, a connecting switch is provided between the oil injection pipeline and the secondary pipeline, and the connecting switch includes a main pipeline installed on the oil injection pipeline and connected to the oil injection pipeline;

[0005] It also includes an intermediate piece installed to the main pipe, wherein a sliding cavity communicating with the main pipe is provided in the intermediate piece, an adjusting piece is slidably connected in the sliding cavity, and a straight hole and a curved hole are provided on the adjusting piece;

[0006] Also included is a driving assembly for driving the adjusting member to slide in the sliding cavity;

[0007] It also includes a branch pipe fixedly connected to the middle piece and in communication with the middle piece, wherein the branch pipe is in communication with the secondary pipeline;

[0008] When the straight hole is aligned with the main pipeline, the main pipeline remains unobstructed; when the curved hole is aligned with the main pipeline, the oil injection pipeline is connected to the branch pipe.

[0009] By adopting the above solution and setting a connecting switch, the connecting switch can control the oil entering the main distributor and the sub-distributor. Under normal conditions, the main distributor is working and the sub-distributor is in standby state to reduce the loss of the sub-distributor. When the main distributor fails, the connecting switch blocks the oil inlet pipeline of the main distributor to facilitate the maintenance of the main distributor.

[0010] Furthermore, the electromagnet, the adsorption member and the elastic member are arranged on a side of the regulating member away from the branch pipe.

[0011] By adopting the above solution, the interference of the driving component on the oil entering the branch pipe is reduced, making the sub-distributor more stable in working state.

[0012] Furthermore, a wiring hole is opened on the mounting seat along the axial direction.

[0013] By adopting the above solution, the arrangement of the electromagnet circuit is facilitated.

[0014] Furthermore, the mounting seat includes a main body and a rotating part, the main body is threadedly connected to the middle piece, the rotating part is located in the sliding cavity and is rotatably connected to the main body, and the electromagnet is fixed to the rotating part.

[0015] By adopting the above solution, during the process of installing the mounting base to the main body or removing it from the main body, the electromagnet is prevented from rotating with the mounting base as much as possible, so that the connection between the electromagnet and the circuit is more stable.

[0016] Furthermore, a positioning rod is provided in the wiring hole, and the positioning rod is fixed to the rotating part.

[0017] By adopting the above solution, during the process of installing the mounting base to the main body or removing it from the main body, the rotating part can be fixed by the positioning rod, so as to avoid the entanglement of the electromagnet circuit as much as possible, and make the connection between the electromagnet and the circuit more stable.

[0018] Furthermore, the positioning rod is a hollow structure, and the positioning rod and the wiring hole are coaxially arranged, and the outer wall of the positioning rod is in contact with the inner wall of the wiring hole and is slidably connected.

[0019] By adopting the above solution, the interference of the positioning rod on the electromagnet circuit is reduced. In summary, the present invention has at least the following beneficial effects: 1. By connecting a secondary distributor in parallel with the forced oil injection system, the problem of the compressor unit shutting down after the main distributor has an oil flow alarm is solved.

[0020] By setting a connecting switch, the connecting switch can control the oil entering the main distributor and the auxiliary distributor. Under normal conditions, the main distributor is working and the auxiliary distributor is in standby state to reduce the loss of the auxiliary distributor. When the main distributor fails, the connecting switch will block the oil inlet pipeline of the main distributor to facilitate the maintenance of the main distributor.

DETAILED DESCRIPTION

[0029] A compressor forced oil injection redundancy system provided by the application embodiment, referring to Figure 1 , including a lubricating oil tank 1, an oil injection pump 2, a main distributor 3 and a redundant system. The oil injection pump 2 is installed to the lubricating oil tank 1. The main distributor 3 is provided with a liquid inlet 31 and several liquid outlets 32. An oil injection pipeline 311 is provided between the liquid inlet 31 of the main distributor 3 and the oil injection pump 2. The oil injection pump 2 pumps the lubricating oil in the lubricating oil tank 1 to the main distributor 3 through the oil injection pipeline 311. An oil distribution pipeline 321 is provided at the liquid outlet 32 ​​of the main distributor 3. The oil distribution pipeline 321 is connected to the lubrication channels of various components of the compressor.

[0030] The redundant system includes a secondary distributor 4, which is provided with an oil inlet 41 and several oil drain holes 42. A secondary pipe 411 is provided between the oil inlet 41 and the oil injection pipe 311, and the oil injection pipe 311 and the secondary pipe 411 are connected. A secondary branch pipe 421 is fixedly connected to and connected to the oil drain hole 42. The several secondary branch pipes 421 correspond to and are connected to the several oil distribution pipes 321.

[0031] By setting up a redundant system, when the main distributor 3 fails, the secondary distributor 4 can continue to keep the entire oil injection system unobstructed, reducing the number of unit failure shutdowns and improving the unit operation rate.

[0032] Furthermore, a connecting switch 5 is provided between the oil injection pipeline 311 and the auxiliary pipeline 411. By setting the connecting switch 5, the oil entering the main distributor 3 and the auxiliary distributor 4 can be controlled. Under normal conditions, the main distributor 3 is working and the auxiliary distributor 4 is in standby state to reduce the loss of the auxiliary distributor 4. When the main distributor 3 fails, the connecting switch 5 blocks the oil inlet pipeline of the main distributor 3 to facilitate the maintenance of the main distributor 3.

[0033] Reference Figure 2 Specifically, the connecting switch 5 includes a main pipeline 51 , and an installation notch is provided on the oil injection pipeline 311 . The main pipeline 51 is provided at the installation notch and both ends are connected to the oil injection pipeline 311 .

[0034] An intermediate piece 52 is provided on the main pipe 51. The intermediate piece 52 is cross-arranged with the main pipe 51, and the angle between the intermediate piece 52 and the main pipe 51 can be set according to actual conditions. In this case, the intermediate piece 52 is perpendicular to the main pipe 51, and a sliding cavity 521 is provided in the intermediate piece 52, which is connected to the main pipe 51.

[0035] A branch pipe 53 is fixedly connected to the middle piece 52 . One end of the branch pipe 53 is communicated with the sliding cavity 521 , and the other end of the branch pipe 53 is communicated with the auxiliary pipeline 411 .

[0036] Reference Figure 3 and Figure 4An adjusting member 54 is slidably connected in the middle member 52 , and a straight hole 541 and a curved hole 542 are formed on the adjusting member 54 .

[0037] Reference Figure 3 and Figure 5 The intermediate member 52 is further provided with a driving assembly 55 for driving the adjusting member 54 to slide within the sliding cavity 521. Specifically, the driving assembly 55 includes an electromagnet 551 disposed within the sliding cavity 521, an elastic member 552 fixedly connected between the adjusting member 54 and the intermediate member 52, and the elastic member 552 is generally a spring, and an adsorption member 553 fixedly connected to the adjusting member 54 for use in conjunction with the electromagnet 551.

[0038] When the adsorption member 553 is adsorbed and fixed by the electromagnet 551 , the straight hole 541 is misaligned with the main pipe 51 and blocked, one end of the curved hole 542 is connected to the main pipe 51 , and the other end of the curved hole 542 is connected to the branch pipe 53 .

[0039] When the electromagnet 551 is powered off, the adsorption member 553 is separated from the electromagnet 551 under the action of the elastic member 552. At this time, the curved hole 542 is misaligned with the main pipe 51 and is blocked, and the straight hole 541 is aligned with the main pipe 51. At this time, the oil injection pipe 311 remains unobstructed and the main distributor 3 works.

[0040] In order to reduce the influence of the driving assembly 55 on the flow rate of the liquid in the branch pipe 53 , the driving assembly 55 is arranged at an end of the regulating member 54 away from the branch pipe 53 .

[0041] Furthermore, to facilitate maintenance and installation of the electromagnet 551, a mounting hole 522 is provided on the end of the intermediate member 52 away from the branch pipe 53. A mounting seat 6 is threadedly connected to the mounting hole 522. One end of the mounting seat 6 extends into the sliding cavity 521, and the electromagnet 551 is mounted to the mounting seat 6. By unscrewing the mounting seat 6, the electromagnet can be removed from the intermediate member 52 for maintenance.

[0042] The mounting base 6 is coaxially provided with a wiring hole 61 for arranging the circuit of the electromagnet 551 .

[0043] Specifically, the mounting seat 6 includes a main body 62 and a rotating part 63. The main body 62 and the rotating part 63 are coaxially arranged. A coaxial middle hole 1 621 is opened on the main body 62. The main body 62 is threadedly connected to the middle piece 52. The rotating part 63 is rotatably connected to the main body 62. A coaxial middle hole 2 631 is opened on the rotating part 63. The connecting hole is aligned with the wiring hole 61 to form the wiring hole 61. The rotating part 63 is coaxially fixed with an annular connecting protrusion 632 on one side facing the main body 62. The corresponding inner wall of the main body 62 is provided with an annular connecting groove 622. The connecting protrusion 632 is embedded in the connecting groove 622, so that the rotating part 63 is rotatably connected to the main body 62.

[0044] A positioning rod 7 is disposed within the wiring hole 61. The positioning rod 7 is fixedly connected to the rotating portion 63, and one end of the positioning rod 7, which is away from the rotating portion 63, extends out of the main body 62. During the process of installing or removing the mounting base 6 from the main body, the positioning rod 7 can be used to fix the rotating portion 63, thereby minimizing the possibility of tangling of the wiring of the electromagnet 551 and ensuring a more stable connection between the electromagnet 551 and the wiring.

[0045] Furthermore, the positioning rod 7 is a hollow tubular structure, and the outer wall of the positioning rod 7 is in contact with and slidably connected to the wiring hole 61. The circuit of the electromagnet 551 passes through the positioning rod 7, thereby reducing the mutual interference between the positioning rod 7 and the circuit of the electromagnet 551.

[0046] Reference Figure 2 A transition pipe 511 is sleeved on both ends of the main pipe 51 and the end of the branch pipe 53 away from the intermediate piece 52. The transition pipe 511 is threadedly connected to the main pipe 51 and to the branch pipe 53. One end of the transition pipe 511 on the main pipe 51 is sleeved onto and threadedly connected to the main pipe 51, and the other end is sleeved onto and threadedly connected to the oil injection pipe 311. One end of the transition pipe 511 on the branch pipe 53 is sleeved onto and threadedly connected to the branch pipe 53, and the other end is sleeved onto and threadedly connected to the secondary pipe 411.

[0047] By setting transition pipes 511 at both ends of the main pipe 51 and the end of the branch pipe 53 away from the middle piece 52, it is convenient to install the connecting switch 5 between the oil injection pipe 311 and the secondary pipe 411, and it is also convenient to modify the forced oil injection system that currently does not have a redundant system.

[0048] Reference Figure 6 A tee pipe 8 is arranged between the secondary branch pipeline 421 and the oil distribution pipeline 321. The three ends of the tee pipe 8 are each sleeved with a connecting pipe 81, and the connecting pipe 81 is threadedly connected to the tee pipe 8. The two connecting pipes 81 on the tee pipe 8 are respectively sleeved into the oil distribution pipeline 321 and threadedly connected to the oil distribution pipeline 321. The other connecting pipe 81 on the tee pipe 8 is sleeved into the secondary branch pipeline 421 and threadedly connected to the secondary branch pipeline 421.

[0049] By providing the tee pipe 8 between the secondary branch pipe 421 and the oil distribution pipe 321 , it is convenient to modify the forced oil injection system that currently does not have a redundant system.

[0050] The implementation principle of this embodiment is: by setting up a redundant system, when the main distributor 3 has an oil flow alarm, it can switch to the auxiliary distributor 4, reducing the number of unit failure shutdowns and improving the unit operation rate.

Identical components are represented by the same reference numerals. Therefore, any effective changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
