Description

Technical Field

[0001] This utility model relates to the field of gear pump technology, and in particular to a lubrication-enhanced gear pump. Background Technology

[0002] In modern industrial production, gear pumps, as an important type of positive displacement pump, have advantages such as simple structure, reliable operation, and stable flow. Gear pumps are widely used in the industrial field to transport various fluid media, such as crude oil, lubricating oil, and asphalt in the petrochemical industry, as well as hydraulic oil transmission in mechanical engineering. However, traditional gear pumps face many problems during operation.

[0003] For example, Chinese patent CN216278463U discloses a lubricating gear pump, including a support base, a retaining ring, an oil tank, and a sealing assembly. The retaining ring is fixed to the upper surface of the support base; the oil tank has an open end suitable for contacting the support base; the open end of the oil tank is inserted into the retaining ring; a limiting ring is provided on the outer peripheral wall of the open end of the oil tank; the sealing assembly is detachably mounted on the retaining ring; the sealing assembly has an air chamber, and the sealing assembly is suitable for pressing against the limiting ring of the oil tank under the action of air pressure.

[0004] Traditional gear pumps often lack sufficient lubrication, especially during high-speed operation or long-term continuous operation. Insufficient lubrication can accelerate the wear of gears and bearings, shorten the service life of the pump, and may also cause the pump body seal to fail due to the high temperature generated by friction, leading to leakage accidents. To address these issues, a gear pump with enhanced lubrication is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a lubrication-enhanced gear pump.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a lubrication-enhanced gear pump, comprising a gear pump mechanism, wherein the gear pump mechanism includes a pump body, a drive shaft, a suction pipe, a discharge pipe, a driving gear, and a driven gear, wherein the driving gear and the driven gear are rotatably mounted inside the pump body, and a lubrication mechanism is fixedly mounted on the top of the pump body, wherein the lubrication mechanism includes an oil reservoir, a support box, a motor, an assembly box, a controller, a reducer, a connecting rod, and an oil drip pipe, wherein the bottom end of the support box is fixedly mounted to the top end of the assembly box, and the top end of the support box is fixedly mounted to the oil reservoir. The bottom of the cylinder is fixedly connected, and a fixed pipe is fixedly connected inside the support box. An oil delivery rod is sleeved inside the fixed pipe. A through hole is opened on one side of the oil delivery rod. An oil inlet hole is opened through the top of the fixed pipe, and an oil outlet hole is opened through the bottom of the fixed pipe. The bottom end of the oil outlet hole is fixedly connected to the top end of the drip pipe. The output end of the motor is connected to one end of the connecting rod through a reducer. A protective pipe is fixedly installed inside the assembly box, and a temperature sensor is fixedly connected inside the bottom end of the protective pipe. The temperature sensor is electrically connected to the controller.

[0007] Preferably, the top of the oil storage cylinder is fixedly connected to a refueling pipe, and the bottom of the oil storage cylinder is fixedly connected to the top of the oil inlet.

[0008] Preferably, the bottom ends of the protective pipe and the drip pipe both extend into the pump body, and the bottom end of the motor is fixedly installed to the outside of the support box.

[0009] Preferably, the controller is fixedly installed at both ends to the outside of the assembly box, and a base is welded to the bottom of the pump body.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the motor drives the connecting rod and the oil delivery rod to rotate at a constant speed through the reducer. When the oil delivery rod rotates to a vertical position with the through hole, the lubricating oil in the oil storage tank flows sequentially through the oil inlet, through hole and oil outlet into the oil dripping pipe. The lubricating oil in the oil dripping pipe drips downwards onto the meshing point of the driving gear and the driven gear, thereby lubricating the gears and bearings inside the gear pump. The device can adjust the speed of the motor through the controller, thereby adjusting the speed of the oil delivery rod, so that the lubricating oil in the oil storage tank is applied to the pump body at a certain frequency. It can provide sufficient, uniform and timely lubrication for the key friction parts inside the gear pump under various working conditions, effectively reducing the coefficient of friction, reducing wear, improving the mechanical efficiency of the gear pump, realizing the intelligent and automated lubrication process, avoiding waste caused by excessive application of lubricating oil, and eliminating the need for frequent manual intervention, thereby improving production efficiency and reducing the risk of human error.

[0015] 2. In this utility model, by adding a temperature sensor, the temperature inside the pump body can be monitored in real time and the temperature information can be transmitted to the controller in real time. The controller receives the temperature information and makes a judgment based on the set temperature parameters. When an abnormal situation of excessive temperature occurs, the pump operation is stopped immediately, and the motor speed is increased at the same time, so that the oil delivery rod rotates faster, increasing the amount of lubricating oil dripping into the pump body, improving the lubrication and cooling effect on the gears inside the pump body, and improving the safety of the device.

However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a lubrication-enhanced gear pump, including a gear pump mechanism 1. The gear pump mechanism 1 includes a pump body 11, a drive shaft 12, a suction pipe 14, a discharge pipe 15, a driving gear 16, and a driven gear 17. The driving gear 16 and the driven gear 17 are rotatably mounted inside the pump body 11. A lubrication mechanism 2 is fixedly mounted on the top of the pump body 11. The lubrication mechanism 2 includes an oil reservoir 21, a support box 23, a motor 24, an assembly box 25, a controller 26, a reducer 27, a connecting rod 28, and an oil drip pipe 214. The bottom end of the support box 23 is fixedly mounted to the top end of the assembly box 25, and the top end of the support box 23 is fixedly mounted to the bottom end of the oil reservoir 21. The connection and support box 23 is fixedly connected to a fixed pipe 211, and an oil delivery rod 29 is sleeved inside the fixed pipe 211. A through hole 210 is opened through one side of the oil delivery rod 29. An oil inlet hole 212 is opened through the top of the fixed pipe 211, and an oil outlet hole 213 is opened through the bottom of the fixed pipe 211. The bottom end of the oil outlet hole 213 is fixedly connected to the top end of the drip pipe 214. The output end of the motor 24 is connected to one end of the connecting rod 28 through a reducer 27. A protective pipe 215 is fixedly installed inside the assembly box 25, and a temperature sensor 216 is fixedly connected inside the bottom end of the protective pipe 215. The temperature sensor 216 is electrically connected to the controller 26.

[0024] The specific settings and functions of this embodiment are described below: The device can adjust the speed of the motor 24 through the controller 26, thereby adjusting the speed of the oil delivery rod 29, so that the lubricating oil in the oil reservoir 21 is applied to the pump body 11 at a certain frequency. It can provide sufficient, uniform and timely lubrication for the key friction parts inside the gear pump under various working conditions, effectively reduce the coefficient of friction, reduce wear, improve the mechanical efficiency of the gear pump, realize the intelligent and automated lubrication process, avoid excessive application of lubricating oil and waste, and at the same time, it does not require frequent manual intervention, improves production efficiency and reduces the risk of human error.

[0025] By adding a temperature sensor 216, the temperature inside the pump body 11 can be monitored in real time, and the temperature information can be transmitted to the controller 26 in real time. The controller 26 receives the temperature information and makes a judgment based on the set temperature parameters. When an abnormal situation of excessive temperature occurs, the pump operation is stopped immediately, and the speed of the motor 24 is increased, so that the oil delivery rod 29 rotates faster, increasing the amount of lubricating oil dripping into the pump body 11, improving the lubrication and cooling effect on the gears inside the pump body 11, and improving the safety of the device.

[0026] Example 2: Figure 1 - Figure 4 As shown, the top of the oil reservoir 21 is fixedly connected to the oil filling pipe 22, and the bottom of the oil reservoir 21 is fixedly connected to the top of the oil inlet 212. The bottom ends of the protective pipe 215 and the drip pipe 214 extend into the pump body 11. The bottom end of the motor 24 is fixedly installed on the outside of the support box 23. The two ends of the controller 26 are fixedly installed on the outside of the assembly box 25. The bottom of the pump body 11 is welded with a base 13. One end of the drive shaft 12 is fixedly connected to one end of the drive gear 16, and the outer wall of the drive gear 16 meshes with the outer wall of the driven gear 17. One end of the pump body 11 is fixedly connected to the suction pipe 14, and the other end of the pump body 11 is fixedly connected to the discharge pipe 15. The motor 24 and the reducer 27 are both electrically connected to the controller 26.

[0027] The overall effect of this embodiment is that the lubricating medium (e.g., lubricating oil) is added into the oil reservoir 21 through the filling pipe 22. After the oil reservoir 21 is filled with a sufficient amount of lubricating oil, the filling pipe 22 is sealed to facilitate the addition of lubricating oil to the oil reservoir 21. During the normal operation of the gear pump, the drive shaft 12 drives the drive gear 16 and the driven gear 17 to rotate at high speed.

[0028] The operation and working principle of this device are as follows: Install the gear pump in the predetermined fluid delivery system, ensuring that the pump body 11 is firmly installed, the inlet and outlet pipes are correctly connected and well sealed. Add the lubricating medium (e.g., lubricating oil) into the oil reservoir 21 through the filling pipe 22. After the oil reservoir 21 has been filled with sufficient lubricating oil, seal the filling pipe 22. During normal operation of the gear pump, the drive shaft 12 drives the driving gear 16 and the driven gear 17 to rotate at high speed. The controller 26 turns on the motor 24, the reducer 27, and the temperature sensor 216. The motor 24 drives the connecting rod 28 and the oil delivery rod 29 to rotate at a constant speed through the reducer 27. A through hole 210 is opened on one side of the oil delivery rod 29. At the same time, an oil inlet hole 212 is opened at the top of the fixed pipe 211, and an oil outlet hole 213 is opened at the bottom of the fixed pipe 211. When the oil delivery rod 29 rotates to the point where the through hole 210 is vertical (e.g., ... Figure 3As shown, one end of the through hole 210 faces the oil inlet hole 212, and the other end faces the oil outlet hole 213. The lubricating oil in the oil reservoir 21 flows sequentially through the oil inlet hole 212, the through hole 210, and the oil outlet hole 213 into the oil dripping pipe 214. The lubricating oil in the oil dripping pipe 214 drips down onto the meshing point of the driving gear 16 and the driven gear 17, thereby lubricating the gears and bearings inside the gear pump. The device can adjust the speed of the motor 24 through the controller 26, thereby adjusting the speed of the oil delivery rod 29, so that the lubricating oil in the oil reservoir 21 is applied to the pump body 11 at a certain frequency. It can provide sufficient, uniform, and timely lubrication for the key friction parts inside the gear pump under various working conditions, effectively reducing the coefficient of friction, reducing wear, and improving the mechanical efficiency of the gear pump. It realizes the intelligent and automated lubrication process, avoids waste caused by excessive application of lubricating oil, and does not require frequent manual intervention, thereby improving production efficiency and reducing the risk of human error.

[0029] By adding a temperature sensor 216, the temperature inside the pump body 11 can be monitored in real time, and the temperature information can be transmitted to the controller 26 in real time. The controller 26 receives the temperature information and makes a judgment based on the set temperature parameters. When an abnormal situation of excessive temperature occurs, the pump operation is stopped immediately, and the speed of the motor 24 is increased, so that the oil delivery rod 29 rotates faster, increasing the amount of lubricating oil dripping into the pump body 11, improving the lubrication and cooling effect on the gears inside the pump body 11, and improving the safety of the device.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
