Description

Technical Field

[0001] This application relates to the technical field of grease dispenser devices, specifically a redundant dispenser. Background Technology

[0002] The continuous and stable operation of many mechanical equipment relies on the supply of lubricating grease to reduce wear and extend service life. However, the lubricating oil demand varies depending on the frequency of movement at different locations of the mechanical equipment. Therefore, a grease distributor is needed to control the amount of oil supplied to each node.

[0003] Existing grease distributors rely on internal plungers to drive and distribute grease in different proportions. In this traditional distributor, if one outlet becomes blocked, the corresponding oil passage and the connecting plunger hole also become blocked, preventing the plunger from moving. Since the entire internal oil passage and plunger hole are interconnected, other outlets will also fail, causing the entire distributor to malfunction. In large enterprises, multiple grease distributors are often connected in series or parallel via pipelines to supply lubricating grease to multiple devices. If even one grease distributor fails, the entire system can easily be paralyzed. Utility Model Content

[0004] This invention addresses the above-mentioned problems by proposing a redundant distributor, aiming to solve the technical issues in the background art.

An oil pump assembly is used to control the oil output of the first oil outlet and the second oil outlet of each of the oil outlet connectors connected to the branch channel. An overflow valve connector, wherein there are multiple overflow valve connectors, is connected to the second oil outlet of the oil outlet connector; the end of the overflow valve connector away from the second oil outlet is provided with a return oil interface; when the first oil outlet cannot be driven to output oil by the oil pump assembly and the pressure exceeds the predetermined pressure of the overflow valve connector, the oil flows through the second oil outlet, through the overflow valve connector, and is discharged from the return oil interface.

[0006] Furthermore, it includes a second oil tank, which has an oil holding chamber inside. Multiple oil return ports are connected to the second oil tank and communicate with the oil holding chamber. The outer wall of the second oil tank is provided with a return connector that communicates with the oil holding chamber.

[0007] Furthermore, it includes a connection module; the connection module is abutted to the first oil tank or the second oil tank; the oil outlet connector passes through the connection module and is connected to the first oil tank; the overflow valve connector is installed on the connection module and docks with the second oil outlet.

[0008] Furthermore, the first oil tank includes a main oil tank and multiple distribution oil tanks; the main flow channel extends from the main oil tank and passes through the multiple distribution oil tanks; the branch channel is located in the distribution oil tank and connects with the main flow channel; the oil outlet connector is connected to the distribution oil tank; the oil pump assembly is an oil pump plunger located in the distribution oil tank.

[0009] Furthermore, when the oil flows through the second oil outlet and exits the return oil interface via the overflow valve connector, an indicator rod extends from the outer wall of the overflow valve connector.

[0010] Further, the overflow valve connector includes a connecting base, an adapter cylinder connected to the connecting base, a connecting rod disposed in the inner holes of the connecting base and the adapter cylinder, an indicator rod disposed in the inner hole of the connecting rod, a safety valve disposed in the inner hole of the connecting base, and a limiting plug connected to the connecting rod; the limiting plug and the safety valve are respectively disposed at both ends of the indicator rod, and the indicator rod passes through the limiting plug; an elastic abutment is provided between the safety valve and the adapter cylinder to keep the safety valve blocking one end of the inner hole of the connecting base; the connecting rod connects to the other end of the inner hole of the connecting base; the connecting rod has a channel section in the inner hole of the adapter cylinder that is smaller than the diameter of the inner hole of the adapter cylinder, and an oil delivery space is provided between the outer wall of the channel section and the inner wall of the adapter cylinder, and the channel section has a connecting hole that connects the inner hole of the connecting rod and the oil delivery space; the adapter cylinder has a cylinder body that communicates with the oil delivery space, and the oil return interface is disposed in the cylinder body.

[0011] Furthermore, the overflow valve connector is equipped with a sensor at the indicator rod to collect information on the extension and retraction status of the indicator rod.

[0012] Furthermore, a one-way valve is provided inside the cylinder.

[0013] Furthermore, the connecting rod and the connecting base clamp and seal both ends of the inner hole of the adapter cylinder; the cylinder body is located on the side wall of the adapter cylinder.

[0015] Compared with the prior art, the redundant distributor provided by this utility model has the following characteristics: if the oil supply demand point corresponding to the first oil outlet of an oil outlet connector becomes abnormally blocked, the second oil outlet, as another oil outlet of the oil outlet connector, applies pressure to the overflow valve connector. When the oil pressure exceeds the predetermined pressure of the overflow valve connector, the oil flows through the second oil outlet and the overflow valve connector to the return oil interface. This eliminates the impact of the blockage of the first oil outlet on the pump assembly corresponding to the branch channel. It also prevents other branch channels and the main channel connected to the branch channel from being affected by pressure buildup, as is the case with traditional distributors. This avoids the pump assembly being unable to drive the oil, and prevents the first oil outlet of all oil outlet connectors from being unable to output the corresponding amount of oil to the oil supply demand point.

[0023] Please refer to Figure 1 - Figure 6 This embodiment provides a redundant allocator, including: A first oil tank 1 has a main channel (not shown) and multiple branch channels (not shown) connected to the main channel inside; an oil inlet 2 is provided corresponding to the main channel; multiple oil outlet connectors 3 are connected to the multiple branch channels on the outer wall of the first oil tank 1; the oil outlet connector 3 is provided with a first oil outlet 310 and a second oil outlet 320. Oil pump assembly 4, which is used to control the oil output of the first oil outlet 310 and the second oil outlet 320 of each of the oil outlet connectors 3 connected to the branch channel; An overflow valve connector 5, of which there are multiple overflow valve connectors 5, is connected to the second oil outlet 320 of the oil outlet connector 3; the end of the overflow valve connector 5 away from the second oil outlet 320 is provided with a return oil interface 510; when the first oil outlet 310 cannot be driven to output oil by the oil pump assembly 4 and the pressure exceeds the predetermined pressure of the overflow valve connector 5, the oil flows through the second oil outlet 320 through the overflow valve connector 5 and is discharged from the return oil interface 510.

[0024] The first oil outlet 310 is directly or indirectly connected to the oil supply demand point via a pipeline.

[0025] With this redundant distributor, when multiple oil outlets 3 supply oil to multiple oil demand points, if the oil demand point corresponding to the first oil outlet 310 of one oil outlet 3 becomes abnormally blocked, the oil pump assembly 4 will be unable to drive the oil flow and will be in a state of pressure buildup. As the oil pump assembly 4 continues to drive, the pressure increases, and the second oil outlet 320, as another oil outlet of the oil outlet 3, applies pressure to the overflow valve connector 5. When the oil pressure exceeds the predetermined pressure of the overflow valve connector 5, the oil flows through the second oil outlet 320 and the overflow valve connector 5 to discharge the return oil interface 510. This eliminates the effect of the blockage of the first oil outlet 310 on the oil pump assembly 4 corresponding to the branch channel, and prevents other branch channels and main channels connected to the branch channel from being affected by pressure buildup, as is the case with traditional distributors. This avoids the oil pump assembly 4 being unable to drive the oil, and prevents all the first oil outlets 310 of the oil outlets 3 from being unable to output the corresponding amount of oil to the oil demand point.

[0026] The return oil port 510 is preferably connected to a liquid supply source that supplies oil to the oil inlet port 2. The oil inlet port 2 receives liquid from the liquid supply source.

[0027] Please refer to Figure 1 and Figure 2 The system includes a second oil tank 6, which has an oil reservoir (not shown) inside. Multiple oil return ports 510 are connected to the second oil tank 6 and communicate with the oil reservoir. The outer wall of the second oil tank 6 is provided with a return connector 610 that communicates with the oil reservoir.

[0028] Multiple return oil ports 510 can be directly connected to the second oil tank 6, or indirectly connected to the second oil tank 6 via pipelines. Then, the oil collected in the oil tank of the second oil tank 6 is centrally transported back to the liquid supply source through the return connector 610.

[0029] Please refer to Figure 1 and Figure 2 It includes a connection module 11; the connection module 11 is abutted to the first oil tank 1 or the second oil tank 6; the oil outlet connector 3 passes through the connection module 11 and is connected to the first oil tank 1; the overflow valve connector 5 is installed on the connection module 11 and docks with the second oil outlet 320.

[0030] By connecting module 11, multiple oil outlet connectors 3 and overflow valve connectors 5 are regularly installed, improving their structural stability and preventing them from easily loosening or shifting under external forces, thus enhancing structural stability.

[0031] Please refer to Figure 1 and Figure 2 The first oil tank 1 includes a main oil tank 110 and a plurality of branch oil tanks 120; the main flow channel extends from the main oil tank 110 and passes through the plurality of branch oil tanks 120; the branch channel is located in the branch oil tank 120 and connects with the main flow channel; the oil outlet connector 3 is connected to the branch oil tank 120; the oil pump assembly 4 is an oil pump plunger located in the branch oil tank 120.

[0032] This design facilitates manufacturing, replacement of parts, and maintenance, thereby reducing costs.

[0033] Please refer to Figure 1 and Figure 4 When the oil flows through the second oil outlet 320 and exits through the overflow valve connector 5 to the return oil interface 510, the indicator rod 520 extends out of the outer wall of the overflow valve connector 5.

[0034] The indicator rod 520 can move and extend as the corresponding valve core inside the overflow valve connector 5 opens, and when it is in the passage state, the indicator rod 520 can also move and extend, making it easy for maintenance personnel to observe and identify the blockage of the corresponding first oil outlet 310 and make corresponding adjustments.

[0035] Please refer to Figure 3 - Figure 5The overflow valve connector 5 includes a connecting base 530, an adapter cylinder 540 connected to the connecting base 530, a connecting rod 550 disposed in the inner holes of the connecting base 530 and the adapter cylinder 540, an indicator rod 520 disposed in the inner hole of the connecting rod 550, a safety valve 560 disposed in the inner hole of the connecting base 530, and a limiting plug 570 connected to the connecting rod 550; the limiting plug 570 and the safety valve 560 are respectively disposed at both ends of the indicator rod 520, and the indicator rod 520 passes through the limiting plug 570; an elastic abutment 580 is provided between the safety valve 560 and the adapter cylinder 540 to maintain the... The safety valve 560 blocks one end of the inner hole of the connecting base 530; the connecting rod 550 connects to the other end of the inner hole of the connecting base 530; the connecting rod 550 has a channel section 551 in the inner hole of the adapter cylinder 540 that is smaller than the diameter of the inner hole of the adapter cylinder 540, and an oil delivery space 590 is provided between the outer wall of the channel section 551 and the inner wall of the adapter cylinder 540; the channel section 551 has a connecting hole 552 that connects the inner hole of the connecting rod 550 and the oil delivery space 590; the adapter cylinder 540 has a cylinder body 541 that communicates with the oil delivery space 590, and the oil return port 510 is located in the cylinder body 541.

[0036] When the first oil outlet 310 is blocked, the pressure driven by the oil pump assembly 4 continues to accumulate. The pressurized oil will push against the safety valve 560, overcoming the elastic force of the elastic support member 580, causing a gap to appear between the safety valve 560 and the connecting base 530. Then the oil can enter the inner hole of the connecting base 530, and then reach the connecting hole 552 along the gap between the inner hole of the indicator rod 520 and the connecting rod 550, and enter the oil delivery space 590. It is then discharged to the liquid supply source through the oil return port 510 provided in the cylinder 541.

[0037] When the safety valve 560 moves under oil pressure, since the indicator rod 520 is located at one end of the safety valve 560 and passes through the limit plug 570, the indicator rod 520 will move with the safety valve 560 and extend out of the outer wall of the relief valve connector 5.

[0038] Please refer to Figure 3 - Figure 5 The overflow valve connector 5 is equipped with a sensor 7 at the indicator rod 520 to collect information on the extension and retraction status of the indicator rod 520.

[0039] Sensor 7 can be any type of device that can detect the displacement of an object, such as a Hall sensor, a through-beam sensor, or a light sensor. Sensor 7 transmits the detected extension / retraction status information of the indicator rod 520 to the host computer, which can then record and trigger an alarm.

[0040] Please refer to Figure 4 and Figure 5 The cylinder 541 is equipped with a one-way valve 10.

[0041] By setting a one-way valve 10, the backflow of oil through the overflow valve connector 5 can be prevented.

[0042] Please refer to Figure 3 - Figure 5 The connecting rod 550 and the connecting base 530 clamp and seal both ends of the inner hole of the adapter cylinder 540; the cylinder body 541 is provided on the side wall of the adapter cylinder 540.

[0043] Please refer to Figure 3 - Figure 5 A sealing ring 8 is provided between the limiting plug 570 and the connecting rod 550 to fit the indicator rod 520; a sealing gasket 9 is provided between the safety valve 560 and the connecting base 530.
