Description

Technical Field

[0001] This application relates to the field of industrial lubrication equipment technology, and in particular to an intelligent lubrication pump with adjustable oil output. Background Technology

[0002] In modern industrial production, lubrication pumps are the core components of equipment lubrication systems, and their performance directly affects the service life and efficiency of the equipment. Existing technologies suffer from two major drawbacks: insufficient precision in oil output adjustment, as traditional lubrication pumps often employ a uniform flow distribution mode, failing to meet the differentiated needs of multiple lubrication points; and low heating efficiency in low-temperature environments, as existing lubrication pumps with heating functions often use a three-layer structure with an oil reservoir wrapped around a heating wire, resulting in a long and inefficient heat conduction path.

[0003] Chinese patent CN222047352U discloses a single-line centralized lubrication system, comprising a first electric lubrication pump and a second electric lubrication pump. The first electric lubrication pump has a main oil supply pipe at its outlet, and multiple secondary oil supply pipes are connected to the outside of the main oil supply pipe via a first distributor. The second electric lubrication pump has a booster main pipe at its outlet, and booster branch pipes connected to each of the secondary oil supply pipes are mounted on the booster main pipe. One end of each secondary oil supply pipe is connected to a feed pipe via a second distributor. By connecting the lubrication points to the secondary oil supply pipes or the feed pipes at the end of the second distributor, the grease requirements of different lubrication points can be met.

[0004] It simply distributes grease evenly by connecting lubrication points to the ends of different distributors, without being able to precisely adjust the oil output at each lubrication point individually. Furthermore, to ensure oil injection efficiency, a second electric valve is required to pressurize the secondary oil supply line at the rear end of the second distributor, which increases the complexity of the system structure and the probability of failure.

[0005] Chinese patent CN203857252U discloses a grease pump with automatic grease heating function, including a pump body and a control box. An oil reservoir is fixed to the upper part of the pump body, which is connected to a motor drive. The oil reservoir is covered with a heating and insulation device, which consists of a heating layer (composed of heating wires), an insulation layer, and a protective cover from the inside out. The control box contains a lubrication pump control device and a temperature control circuit. A digital display heating controller detects the temperature through a temperature probe and controls the operation of the heating layer.

[0006] Its heating and insulation device adopts a three-layer structure of heating layer, insulation layer and protective cover, which is relatively complex. Since the heating device covers the outside of the oil storage tank, the heat conduction direction is from the outside to the inside, while the oil outlet of the pump body is located at the bottom of the oil storage tank, resulting in low heat conduction efficiency and long heating time, making it difficult to quickly meet the lubrication needs in low temperature environments. Utility Model Content

[0011] Optionally, the drive motor and the transmission shaft are driven by gears, and a spring for plunger reset is provided between the plunger and the oil outlet core.

[0012] Optionally, a heating film is provided at the end of the oil cup base away from the oil cup, and a liquid level detection switch and a temperature sensor extending to the outside are provided inside the oil cup base.

[0014] 1. By setting up an oil cup for storing lubricating grease, an oil cup base is set at the bottom of the oil cup, and multiple oil outlet components are set on the oil cup base. The oil output of multiple oil outlet components can be adjusted individually according to actual needs to meet the differentiated lubrication requirements of different lubrication points.

[0016] 3. By installing a temperature sensor on the oil cup base and connecting it to the intelligent controller, the temperature of the grease can be detected and preheated before lubrication begins, and the temperature of the grease can be detected in real time during the start-up of the lubrication pump. This ensures that the viscosity of the grease remains stable within a suitable pumping range at low temperatures, thus avoiding lubrication failure. Attached Figure Description

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-4This application will be described in further detail.

[0023] This application discloses an intelligent lubrication pump with adjustable oil output. For example... Figure 1 and 2 As shown, the system includes an intelligent controller 1, a drive base 2, and an oil cup assembly 3 connected to the drive base 2 via an oil cup base 4. The oil cup assembly 3 includes an oil cup, which is a hollow cylindrical structure. An oil seal 33 is provided on the inner wall of the oil cup, and an oil pressure plate 31 is provided on the oil seal 33. A tower-shaped spring 32 is provided between the oil pressure plate 31 and the bottom of the oil cup. The oil cup is connected to the oil cup base 4, and an oil replenishment port 6 for replenishing lubricating grease is provided on the oil cup base 4. Multiple oil outlet components 5 are provided on the oil cup base 4 and are evenly spaced. The oil outlet assembly 5 includes an oil outlet core 52 connected to the oil cup base 4 via a thread 503. One end of the oil outlet core 52, located inside the oil cup base 4, has an oil inlet hole 505 communicating with the oil cup. A plunger 51 for pushing lubricating grease is slidably connected to one end of the oil inlet hole 505. A retaining ring is provided at one end of the plunger 51, and a spring 56 for resetting the plunger 51 is provided between the retaining ring and the oil outlet core 52. An oil inlet cavity 501 communicating with the oil inlet hole 505 is provided inside the oil outlet core 52. An oil outlet cavity 502 communicating with the oil inlet cavity 501 is provided at the end of the oil outlet core 52 away from the plunger 51. A one-way valve assembly 53, which is prior art, is provided at the end of the oil outlet core 52 away from the plunger 51. The oil outlet 57 communicating with the oil outlet cavity 502 is connected to a lubrication point. The drive base 2 is equipped with a drive motor 71 and a transmission shaft 72. The drive motor 71 and the transmission shaft 72 are driven by gears. The end of the transmission shaft 72 away from the drive motor 71 extends into the oil cup base 4. An eccentric wheel 73 for adjusting the position of the plunger 51 is keyed to the transmission shaft 72. When the drive motor 71 drives the transmission shaft 72 to rotate, the eccentric wheel 73 will drive the plunger 51 to move and adjust the oil inlet hole 505.

[0024] In one embodiment, according to the appendix Figure 4As shown, the oil outlet core 52 is provided with an oil return hole 500 for connecting the oil outlet chamber 502 and the oil cup. The oil outlet core 52 is also provided with a threaded hole 504 communicating with the oil return hole 500. An adjusting bolt 55 is installed inside the threaded hole 504, and the adjusting bolt 55 has a scale. By moving the position of the adjusting bolt 55, the size of the channel connecting the oil return hole 500 and the oil cup can be adjusted. This allows for adjustment of the amount of lubricating grease entering the oil cup from the oil return hole 500, indirectly adjusting the amount of grease output from the oil outlet 57. An overflow valve assembly 54 is provided at one end of the oil outlet core 52 located outside the oil cup base 4. The overflow valve assembly 54 is prior art and is used to adjust the oil outlet pressure of the oil outlet 57. When the pressure exceeds a set value, the lubricating grease flows back into the pump body through the resin hose, ensuring system safety.

[0025] In one embodiment, according to the appendix Figure 3 As shown, a groove is provided at the end of the oil cup base 4 away from the oil cup, and a heating film 41 is bonded to the groove. The heating film 41 is existing technology. A heat-insulating pad 21 is provided between the drive base 2 and the oil cup base 4. A liquid level detection switch 42 and a temperature sensor 43 extending into the drive base 2 are provided inside the oil cup base 4. The intelligent controller 1 is electrically connected to the heating film 41, the liquid level detection switch 42, the temperature sensor 43 and the drive motor 71 via an aviation plug 22.

[0026] The implementation principle of an intelligent lubrication pump with adjustable oil output according to an embodiment of this application is as follows: In the initial state, under the action of the oil pressure plate 31, the plunger 51 forces the grease in the oil cup into the oil inlet chamber 501 through the oil inlet hole 505. The intelligent controller 1 controls the drive motor 71 to rotate, the drive motor 71 drives the transmission shaft 72 to rotate, the transmission shaft 72 drives the eccentric wheel 73 to rotate, and the eccentric wheel 73 drives the plunger 51 to move to the right. The plunger 51 squeezes the grease in the chamber. Part of the squeezed grease enters the oil outlet chamber 502 through the one-way valve assembly 53 and is output through the oil outlet 57, while part of it flows back into the oil cup through the oil return hole 500.

[0027] When the adjusting bolt 55 completely closes the oil return hole 500, the communication channel between the oil return hole 500 and the oil cup is completely closed. At this time, all the grease in the oil inlet chamber 501 enters the oil outlet chamber 502 through the one-way valve assembly 53 and is output through the oil outlet 57. At this time, the amount of lubricating grease output is the maximum output amount designed, which is the volume of the oil outlet chamber 502.

[0028] When the adjusting bolt 55 fully opens the return oil hole 500, the communication channel between the return oil hole 500 and the oil cup is fully opened. At this time, due to the set opening pressure of the one-way valve assembly 53, all the lubricating grease in the oil outlet chamber 502 enters the oil cup through the return oil hole 500, and no lubricating grease is output from the oil outlet 57. At this time, the output lubricating grease amount is 0.

[0029] By adjusting the position of the adjusting bolt 55, the size of the channel connecting the oil return hole 500 and the oil cup can be adjusted. This, in turn, can adjust the amount of lubricating grease entering the oil cup from the oil return hole 500, indirectly adjusting the output of lubricating grease through the oil outlet 57.

[0030] The adjusting bolt 55 is equipped with a scale indicating the amount of lubricating grease output through the oil outlet 57. In actual use, the position of the adjusting bolt 55 can be moved according to the required amount of lubricating grease, so that the oil outlet 57 can dynamically adjust the single oil output according to the actual needs of the lubrication point, meeting the differentiated grease requirements of different lubrication points.

[0031] The heating process of lubricating grease:

[0032] Based on the characteristics of the lubricating grease used, the optimal operating temperature range of the lubricating grease is set by the intelligent controller 1.

[0033] The intelligent controller 1 controls the lubrication pump to operate intermittently. Before the end of each intermittent cycle, the intelligent controller 1 collects the real-time temperature of the lubricating grease in the oil cup via temperature sensor 43. When the detected lubricating grease temperature is lower than the minimum value of the set temperature range, the intelligent controller 1 activates the heating film 41. The heating film 41 transfers heat to the lubricating grease at the bottom of the oil cup through the aluminum alloy oil cup base 4. During the heating process, the temperature of the lubricating grease in the oil cup is monitored in real time. When the detected lubricating grease temperature is higher than the minimum temperature of the set temperature range, the intelligent controller 1 stops the heating film 41. Real-time monitoring of the lubricating grease temperature during heating ensures that the grease temperature does not exceed the set maximum temperature, preventing excessively high temperatures from causing lubricating grease failure.

[0034] If the heating process is completed before the end of the intermittent cycle, the intelligent controller 1 will monitor the temperature of the lubricating grease in real time to ensure that the temperature of the lubricating grease remains within the optimal operating temperature range during the lubrication process until the lubrication is completed.

[0035] If the heating process is not completed by the end of the intermittent cycle, the intelligent controller 1 will start the lubrication pump after the heating process is completed to ensure that the viscosity of the lubricating grease remains stable within the appropriate pumping range at low temperatures.

[0036] 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.
