Description

Technical Field

[0001] The utility model relates to the technical field of gears, in particular to a lubricating device for a gear pump. Background Technique

[0002] A gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquids or increase their pressure. It consists of two gears, a pump body, and front and rear covers, forming two closed spaces. When the gears rotate, the volume of the space on the side where the gears disengage increases from small to large, creating a vacuum and sucking in the liquid. The volume of the space on the side where the gears mesh decreases from large to small, squeezing the liquid into the pipeline. The suction chamber and the discharge chamber are separated by the meshing line of the two gears. The pressure at the discharge port of the gear pump completely depends on the magnitude of the resistance at the pump outlet. Its most basic form is two gears of the same size meshing and rotating with each other in a closely fitted housing. The inside of this housing is similar to an "8" shape, with two gears installed inside. The outer diameter and both sides of the gears are closely fitted with the housing. The material from the extruder enters the space between the two gears at the suction port and fills this space. As the teeth rotate, it moves along the housing and is finally discharged when the two teeth mesh.

[0003] After retrieval, the Chinese utility model patent discloses a lubricating device for a gear pump with the publication number CN 207777167 U. It includes a pump body, an oil tank, a pressure plate, and a motor. A first gear is arranged on the upper side inside the pump body. An oil suction port is arranged on the left side of the pump body. A support plate is fixed on the lower side of the pump body. The oil tank is connected to the pump body through a threaded buckle. The pressure plate is connected to the oil tank through a slide rail. An electric telescopic rod is connected to the upper side of the pressure plate. An air outlet is arranged at the upper end of the oil tank. The motor is located at the rear side of the pump body and on the upper end of the support plate. A first rotating shaft is arranged on the motor, and the first rotating shaft is connected to the first gear through a second rotating shaft. This lubricating device for a gear pump solves the problems of continuous friction between gears, causing damage and inconvenience in replacement, solves the problem of easy oil leakage from the air outlet and the oil filling port, resulting in waste, and solves the problem of untimely oil supply caused by the change of air pressure inside the pump body, leading to air pressure difference inside the oil tank.

[0004] However, this device lacks a temperature detection function. When the internal gears of the gear pump rotate during use, frictional heat will be generated, resulting in a temperature rise. When the temperature of the pump is too high, it may lead to a decline in the sealing performance, causing oil leakage. Moreover, this device also lacks an oil filtering function. When in use, the oil directly enters the pump body without passing through an oil filter, and it is very easy to bring impurities in the oil into the friction surface of the parts, accelerating the wear of the parts.

Detailed Description of the Preferred Embodiment

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 As shown, a technical solution provided by the present utility model:

[0024] A lubrication device of a gear pump includes a fixed plate 01. One end of the upper surface of the fixed plate 01 is fixedly connected with a first mounting seat 02. The top of the first mounting seat 02 is fixedly connected with a pump body 04. A gear shaft 16 is rotatably connected inside the pump body 04. One end of the gear shaft 16 is rotatably connected with a rotating motor 17. During use, after the rotating motor 17 is started, it drives the gear shaft 16 to rotate, so that the gear pump starts to work. The pump body 04 is fixed on the fixed plate 01 through the first mounting seat 02, which can prevent the device from shifting due to the vibration of the motor during use;

[0025] On the other end of the upper surface of the fixed plate 01, there is a second mounting seat 03 fixedly connected. On the top of the second mounting seat 03, there is a rotating motor 17 fixedly connected. On one side of the rotating motor 17, there is an adjustment button fixedly connected. The gear pump rotates by the meshing of two gears with the same size in a closely fitted housing. The engine oil enters between the two gears. With the rotational movement of the teeth, it is finally discharged when the two teeth are meshed. The rotating motor 17 can control the switch and adjust the speed, so as to meet different production requirements.

[0026] In this embodiment, preferably, on the outer side of the top of the pump body 04, there is a HUASOET quick temperature measuring instrument 05 fixedly connected. At the top end inside the pump body 04, there is a temperature measuring probe 06 fixedly connected. One end of the temperature measuring probe 06 is fixedly connected to the HUASOET quick temperature measuring instrument 05. Through the settings of the HUASOET quick temperature measuring instrument 05 and the temperature measuring probe 06, during use, it can detect the real-time temperature of the engine oil rotating and lubricating inside the pump body 04. When the rotational speed is too high, it will cause the temperature to rise, which will reduce the material strength of the gear pump, thus increasing the risks of leakage and sliding. The friction increases under high-temperature conditions, which will lead to poor lubrication and increased wear.

[0027] In this embodiment, preferably, on one end of the pump body 04, there is an oil outlet 07 opened. Inside the pump body 04, there is a pump chamber 13. On the other end of the pump body 04, there is an oil inlet 08 opened. During use, the engine oil enters the pump chamber 13 through the oil inlet 08, fills the gaps between the gears, and is compressed and pushed to the oil outlet 07 as the gears rotate. The structure is compact and the work is reliable.

[0028] In this embodiment, preferably, one end of the pump body 04 is threadedly connected with a threaded pipe 10. On one end of the threaded pipe 10, there is a clamping groove 11 opened. Inside the pipe orifice 09, there is a clamping part fixedly connected with the same size as the clamping groove 11. During use, the operator tightly clamps the clamping part of the pipe orifice 09 in the clamping groove 11 and turns it counterclockwise to fasten the pipe orifice 09 on the threaded pipe 10, which is convenient for the connection and disassembly of the engine oil pipeline.

[0029] In this embodiment, preferably, an oil filter element 12 is clamped inside the threaded pipe 10. On both sides of the oil filter element 12, there are skeletons fixedly connected. Inside the skeletons, there is a stainless steel braided mesh fixedly connected. Between the stainless steel braided meshes, there is glass fiber filled. When the engine oil passes through the oil filter element 12, the stainless steel braided mesh and glass fiber inside the oil filter element 12 can remove the metal powder, other impurities and moisture in the engine oil, keep the oil circuit clean, and thus reduce the wear of the internal parts of the gear pump.

[0030] In this embodiment, preferably, one end of the rotating motor 17 is rotatably connected to a gear shaft 16. One end of the gear shaft 16 is fixedly connected to a driving gear 14. A driven gear 15 is meshed and connected to the lower side of the driving gear 14. During use, engine oil enters between the driving gear 14 and the driven gear 15. Along with the rotational movement of the gear shaft 16, the compressed engine oil is pushed to the oil outlet 07 and discharged when the two gears are meshed, ensuring the lubrication effect of the gears.

[0031] When the gear pump lubrication device of this embodiment is in use, after the rotating motor 17 is started, it drives the gear shaft 16 to rotate, thereby enabling the gear pump to start working. The engine oil enters between the driving gear 14 and the driven gear 15 after being filtered through the oil inlet 08. Along with the rotational movement of the gear shaft 16, the compressed engine oil is pushed to the oil outlet 07. The HUASOET quick temperature measuring instrument 05 and the temperature measuring probe 06 can detect the real-time temperature of the engine oil rotating and lubricating in the pump body 04, preventing poor lubrication and increased wear caused by too high oil temperature. The rotating motor 17 can maintain an appropriate engine oil temperature by controlling the motor switch and adjusting the rotational speed of the gear shaft 16. The pump body 04 is fixed on the fixing plate 01 through the first mounting seat 02, and the rotating motor 17 is fixed on the fixing plate 01 through the second mounting seat 03, which can prevent the device from shifting due to motor vibration during use.
