Description

Technical Field

[0001] The utility model relates to the technical field of gear pump equipment, and more specifically, to a gear pump with a lubricating function. Background Art

[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 liquid or increase its pressure. It consists of two closed spaces, two gears, a pump body, and front and rear covers. When the gears rotate, the volume of the space on the gear disengagement side changes from small to large, forming a vacuum, sucking the liquid in, and the volume of the space on the gear meshing side changes 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 depends entirely on the size of the resistance at the pump outlet. In fact, there is a small amount of fluid loss in the pump because the fluid is used to lubricate the bearings and both sides of the gears, and the pump body can never fit without clearance.

[0003] For example, the patent document with the announcement number CN 221400905 U discloses a gear pump with a lubrication structure, including a pump housing and a drive assembly, the pump housing including a first inner wall and a second inner wall arranged opposite to each other in the axial direction, the drive assembly being arranged in a cavity, including a first gear and a second gear meshing with each other, the meshing of the first gear and the second gear forming a meshing gap, a liquid guide groove being provided on the first inner wall and / or the second inner wall, the liquid guide groove being connected to the meshing gap, and one end extending to the end side of the first gear and the other end extending to the end side of the second gear. In the present utility model, the liquid guide groove guides liquid from the meshing gap into the gap between the end sides of the first gear and the second gear and the inner wall, thereby playing a lubricating role, reducing the frictional resistance between the inner wall and the first gear and the second gear, reducing the wear of the first gear and the second gear during operation, thereby improving the working efficiency and service life of the gear pump.

[0004] However, during actual use, due to the limitations of its own structure, this structure can only perform sealing and lubricating operations between the bearings inside the gear pump and the lubricating oil. After lubrication for a period of time, the lubricating oil is very likely to carry a large amount of debris generated by metal friction. At this time, the lubrication effect becomes worse. If it is not replaced in time, abnormal wear of the debris may also occur. It is impossible to achieve the lubrication operation of the gear pump with flowing lubricating oil and efficient filtration. At the same time, the equipment cannot perform synchronous lubrication operations on the valve seat infusion at the inlet and outlet of the gear pump, and cannot meet daily use needs. Therefore, in order to solve the above technical problems, this application proposes a gear pump with lubrication function. Utility Model Content

[0005] During actual use, the existing structure can only perform the sealing and lubrication operation between the bearings inside the gear pump and the lubricating oil due to its own structural limitations. After lubrication for a period of time, the lubricating oil is very likely to carry a large amount of debris generated by metal friction. At this time, the lubrication effect becomes poor. If it is not replaced in time, abnormal wear of the debris may also occur. It is impossible to achieve the lubrication operation of the gear pump with flowing lubricating oil and efficient filtration. At the same time, the equipment cannot perform the synchronous lubrication operation of the valve seat infusion at the inlet and outlet of the gear pump, and cannot meet daily use needs. In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gear pump with lubrication function.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: comprising a first gear cover, a second gear cover is provided at the bottom end of the first gear cover, the first gear cover and the second gear cover have the same structure, one side of the first gear cover and the second gear cover are fixedly connected to a water inlet side frame, and the other side of the first gear cover and the second gear cover are fixedly connected to a drainage side frame, and the upper and lower ends of the water inlet side frame and the drainage side frame are provided with circulation hidden pipes;

[0007] A pressurized top seat and a flow base, the top end of the first gear cover is fixedly connected to the pressurized top seat, the bottom end of the second gear cover is fixedly connected to the flow base, and a pressurized micro pump is provided on the top of the pressurized top seat.

[0008] Preferably, the bottom end of the flow base is fixedly connected to a diversion seat, and the bottom end of the diversion seat is movably connected to a filter pot.

[0009] Preferably, a filter core is provided inside the filter pot, and a diverter valve seat is provided inside the diverter seat.

[0010] Preferably, the front sides of the pressurized top seat and the flow base are provided with circulating open pipes, and the interior of the circulating open pipes is intermittently provided with oil control valve seats.

[0011] Preferably, flow guide side seats are provided on both sides of the oil control valve seat, and a lubricating sleeve is provided on the back of the flow guide side seat.

[0012] Preferably, a delivery socket is provided inside the drainage side frame, and a turbofan shaft wheel is provided on the inner wall of the delivery socket.

[0013] Preferably, the hidden circulation tube is adapted to the interior of the delivery socket.

[0014] Preferably, the pressurizing top seat and the flow base are adapted to fit each other.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the utility model, a more efficient lubricating oil flow filtration operation of the gear pump can be achieved through the first gear cover, the second gear cover, the pressurized top seat, the flow base, the pressurized micro pump, the diverter seat, the filter pot, the filter element, the diverter valve seat, the circulating exposed pipe, the oil control valve seat, the guide side seat and the lubricating sleeve. In the actual use process, the staff first adaptably installs the gear pump inside the cover connection structure composed of the first gear cover and the second gear cover. At this time, the shaft positions of the two end groups of gears in the core of the gear pump can be adaptively plugged and installed inside the lubricating sleeve inside the oil control valve seat, and the positioning installation and use are quickly completed. When the gear pump is used for pumping water in daily life, the pressurized top seat can be synchronously driven. The micro pump will be used to perform rapid pressurized flow operations on the gear pump lubricating oil. At this time, the lubricating oil can quickly flow from the oil control valve seat to the inside of the two sets of lubricating sleeves along the circulating exposed pipe at high speed to perform lubrication operations inside the lubricating sleeves. The diversion side seats on both sides of the oil control valve seat perform rapid diversion operations on the gear pump lubricating oil, thereby ensuring that the gear pump can quickly reach the flow base at the bottom of the second gear cover along the circulating exposed pipe. At the same time, the gear pump lubricating oil entering the flow base can enter the inside of the filter pot from the diverter seat, be filtered through the filter element inside the filter pot, and then be diverted inside and outside through the diverter valve seat inside the diverter seat, thereby quickly realizing the filtering and use operations of the lubricating oil, reflecting the practicality of the equipment design.

[0017] 2. In the present invention, the overall use effect of the equipment is further improved through the first gear cover, the second gear cover, the water inlet side frame, the drainage side frame, the circulation hidden pipe, the delivery seat and the turbofan shaft wheel. In daily use, after the lubricating oil at the flow base is filtered, it can be returned to the inside of the pressurized top seat through the water inlet side frames and drainage side frames on both sides of the first gear cover and the second gear cover in cooperation with the circulation hidden pipes at the upper and lower ends, thereby realizing efficient circulation and use of the gear pump lubricating oil. At the same time, when the water inlet side frames and drainage side frames on both sides of the first gear cover and the second gear cover are used to pump and discharge water through the delivery seat, the turbofan shaft wheel inside the delivery seat can rotate at high speed with the water flow to perform vortex acceleration of the water flow, and the turbofan shaft wheel can also perform sealing and lubrication operations inside the delivery seat, reflecting the comprehensiveness of the equipment design.
