Description

Technical Field

[0001] This utility model belongs to the field of mechanical pump technology, and in particular relates to a mechanical pump for isolating air bubbles in a hydraulic system. Background Technology

[0002] A mechanical pump in a hydraulic system is a power component that converts mechanical energy into hydraulic energy through mechanical motion. Its core function is to provide a continuous and controllable pressurized hydraulic fluid to the hydraulic system. The mechanical pump draws in low-pressure hydraulic fluid, compresses it, and then discharges high-pressure hydraulic fluid to drive the actuator to perform work.

[0003] When a hydraulic system's mechanical pump delivers hydraulic oil, air easily gets trapped as the oil flows through various pipelines, valves, and storage containers. This air disperses in the hydraulic oil as tiny bubbles and enters the delivery process along with the oil. These seemingly small bubbles exhibit highly destructive properties under high pressure. When hydraulic oil containing air bubbles enters the mechanical pump, the rapid increase in pump pressure causes the bubbles to compress and burst quickly. At the moment of bursting, the surrounding hydraulic oil rushes at extremely high speed into the space previously occupied by the bubbles, creating a powerful shock wave. This impact force acts directly on the inner wall of the mechanical pump, and over time, this gradually leads to cavitation.

[0004] Cavitation creates pits and depressions that continuously expand, not only damaging the smoothness of the pump's inner wall but also weakening its structural strength. This results in greater resistance to hydraulic oil flow, impacting delivery efficiency. More seriously, as cavitation intensifies, precision components inside the pump, such as impellers and bearings, deform and become damaged due to continuous impact and wear. This leads to a significant decrease in pump performance, causing problems like unstable pressure and flow fluctuations. A pump that could previously operate stably for thousands of hours may require major repairs or even replacement in a short period due to persistent cavitation, greatly increasing maintenance costs and downtime, and severely threatening the operational stability of the entire hydraulic system.

[0005] This chain reaction caused by air bubbles, from the initial introduction of tiny air bubbles to the occurrence of cavitation, and then to the damage and shortening of the lifespan of mechanical pumps, accumulates continuously during the operation of the hydraulic system and may eventually lead to more serious failures, affecting the normal operation of the entire production or work process. Utility Model Content

[0006] The purpose of this invention is to address the aforementioned technical problems by providing a hydraulic system bubble isolation mechanical pump, which facilitates the removal of air bubbles from the pumped hydraulic oil and prevents air bubbles from impacting the pump body and causing damage.

[0007] In view of this, the present invention provides a hydraulic system bubble isolation mechanical pump, comprising:

[0008] The mechanical pump body has a detachable pipe three installed at its front end. A cylinder is fixed at the front end of the pipe three. A pipe four is fixed at the front end of the cylinder. A conveying pipe one is fixed at the upper end of the cylinder. A conveying pipe two is fixed at the lower end of the cylinder. An auger blade is rotatably connected to the inner cavity of the conveying pipe one. The lower end of the auger blade extends into the inner cavity of the conveying pipe two.

[0012] Furthermore, the auger blade is rotatably connected to the top of the inner wall of the first conveying trough, and the lower end of the auger blade extends through the cylindrical groove into the second conveying trough. A circular hole is opened at the upper end of the first conveying pipe, and a motor is fixed at the upper end of the first conveying pipe. The drive end of the motor extends into the circular hole and is connected to the auger blade.

[0013] Furthermore, adhesive strips are installed on the sidewalls of the auger blades, and the adhesive strips are respectively attached to the inner walls of conveying groove one and conveying groove two.

[0014] Furthermore, an outlet pipe is fixed at the lower end of the second conveying pipe, and a valve is installed at the front end of the outer wall of the outlet pipe.

[0015] Furthermore, the first conveying groove of the first conveying pipe is aligned with the second conveying groove of the second conveying pipe along their vertical axes.

[0016] Furthermore, the mechanical pump body has a fixed pipe 1 at its rear end and a fixed pipe 2 at its front end. The outer wall of the pipe 2 has a fixed mounting ring 1 at its front end and a fixed mounting ring 2 at its rear end.

The hydraulic oil in the cylinder groove is conveyed and rotated simultaneously, positioning the auger blade in the air bubble collection groove. The collected air bubbles are then conveyed to the conveying groove two through the auger blade, and then some of the hydraulic oil and air bubbles are discharged through the outlet pipe. This achieves the effect of facilitating the discharge of air bubbles from the conveyed hydraulic oil and preventing air bubbles from impacting the mechanical pump body and causing damage.

[0035] Please see Figures 1 to 8 The embodiments provided by this utility model are as follows:

[0036] Example: A hydraulic system bubble isolation mechanical pump, comprising:

[0037] Mechanical pump body 1, mechanical pump body 1 has a detachable pipe 3 7 at the front end, a cylinder 8 is fixed at the front end of the pipe 3 7, a pipe 4 10 is fixed at the front end of the cylinder 8, a conveying pipe 1 9 is fixed at the upper end of the cylinder 8, a conveying pipe 2 12 is fixed at the lower end of the cylinder 8, an auger blade 19 is rotatably connected to the inner cavity of the conveying pipe 1 9, and the lower end of the auger blade 19 extends into the inner cavity of the conveying pipe 2 12.

[0038] The mechanical pump body 1, as the core working component, is connected to the cylinder 8 via a detachable pipe 3 7 at its front end. This connection method ensures structural stability and greatly facilitates subsequent maintenance and component replacement. The cylinder 8, as the key area for bubble isolation, is connected to pipe 4 10 at its front end, with delivery pipe 1 9 and delivery pipe 2 12 fixed at its upper and lower ends respectively, forming a relatively independent and fully functional bubble treatment space. Crucially, the lower end of the auger blade 19 inside delivery pipe 1 9 extends into the inner cavity of delivery pipe 2 12. When hydraulic oil enters the cylinder 8 from pipe 4 10, it does not flow directly to the mechanical pump body 1, but first interacts with the auger blade 19 within the cylinder 8. The rotation of the auger blade 19 continuously agitates the hydraulic oil, causing the bubbles originally mixed in the hydraulic oil to gradually appear and aggregate under external force. Simultaneously, the delivery function of the auger blade 19 guides the hydraulic oil with initially separated bubbles towards the mechanical pump body 1, effectively preventing a large number of bubbles from directly entering the mechanical pump body 1. It is important to know that air bubbles entering the mechanical pump body 1 will seriously affect the stability of its pressure output and may even cause abnormal wear of the pump body. This structural design intercepts and treats air bubbles at the source, which greatly ensures the normal working condition of the mechanical pump body 1 and extends its service life.

[0039] A conveying groove 18 is opened at the lower end of the conveying pipe 19, a conveying groove 22 is opened at the upper end of the conveying pipe 21, a cylinder groove 15 is opened inside the cylinder 8, a through hole 16 is opened at the upper end of the cylinder 8, and a through hole 21 is opened at the lower end of the cylinder 8.

[0040] To ensure a more orderly and efficient bubble separation process, a conveying trough 18 is provided at the lower end of conveying pipe 1 9, and a conveying trough 22 is provided at the upper end of conveying pipe 2 12. These two troughs act as channels specifically designed for hydraulic oil and bubbles, guiding them to flow along a specific trajectory. The cylindrical groove 15 inside cylinder 8 serves as the main space for the initial mixing of hydraulic oil and the initial separation of bubbles. When hydraulic oil enters the cylindrical groove 15, it receives a certain buffer and residence time, allowing bubbles to separate from the hydraulic oil. Simultaneously, the through hole 16 at the upper end and the through hole 21 at the lower end of cylinder 8 connect the various spaces, acting as bridges to allow the hydraulic oil and separated bubbles to flow smoothly between the cylindrical groove 15, conveying trough 18, and conveying trough 22. Without the grooves and through holes, the flow of hydraulic oil within cylinder 8 would become chaotic and disorderly, potentially causing bubbles to accumulate in certain areas and become ineffective, ultimately affecting the overall bubble separation effect. With these structures, the flow path of hydraulic oil is clearly planned, and the bubble separation process can proceed steadily according to the preset procedure, greatly improving the reliability of bubble isolation.

[0041] The through hole 16 of the cylinder 8 is connected to the groove 15 of the cylinder 8. The through hole 16 of the cylinder 8 is connected to the conveying groove 18 of the conveying pipe 9. The through hole 21 of the cylinder 8 is connected to the groove 15 of the cylinder 8. The through hole 21 of the cylinder 8 is connected to the conveying groove 22 of the conveying pipe 12.

[0042] One end of the through hole 16 on the cylinder 8 is connected to the cylinder groove 15, and the other end is connected to the conveying groove 18 of the conveying pipe 9. This allows some of the air bubbles separated in the cylinder groove 15 to enter the conveying groove 18 through the through hole 16, and then be conveyed upwards by the auger blades 19. Similarly, the through hole 21 connects the cylinder groove 15 and the conveying groove 22 of the conveying pipe 12, allowing the pre-treated hydraulic oil to flow smoothly from the cylinder groove 15 into the conveying groove 22 for further processing or conveying. This interconnected structure forms a complete closed loop. From the moment the hydraulic oil enters the cylinder groove 15, to the separation of air bubbles into the conveying groove 18, and then to the processing of the hydraulic oil into the conveying groove 22, the entire process is continuous and efficient. The separated air bubbles can be quickly conveyed and discharged along specific channels without lingering in the system, thus preventing air bubbles from mixing back into the hydraulic oil, further improving the efficiency of air bubble isolation, and ensuring that the hydraulic oil entering the mechanical pump body 1 has high purity.

[0043] The auger blade 19 is rotatably connected to the top of the inner wall of the first conveying trough 18. The lower end of the auger blade 19 extends through the cylindrical groove 15 into the second conveying trough 22. A round hole 17 is opened at the upper end of the first conveying pipe 9. The motor 2 is fixed at the upper end of the first conveying pipe 9. The driving end of the motor 2 extends into the round hole 17 and is connected to the auger blade 19.

[0044] The installation and driving mechanism of the auger blade 19 provides strong power support for bubble separation. It is rotatably connected to the top of the inner wall of the first conveying trough 18, and its lower end extends through the cylindrical groove 15 of the cylinder 8 into the second conveying trough 22. This through-type design allows the auger blade 19 to simultaneously act on three areas: the first conveying trough 18, the cylindrical groove 15, and the second conveying trough 22, ensuring comprehensive treatment of the hydraulic oil within the entire cylinder 8. The circular hole 17 at the upper end of the first conveying pipe 9 provides a channel for the drive end of the motor 2 to extend. When the motor 2 is working, its drive end drives the auger blade 19 to rotate continuously. During rotation, the spiral structure of the auger blade 19 generates a strong spiral thrust on the surrounding hydraulic oil. This thrust, on the one hand, propels the hydraulic oil to flow rapidly in each trough and channel, improving overall processing efficiency; on the other hand, due to the centrifugal force generated by the spiral motion, bubbles in the hydraulic oil are collected and moved upwards under the spiral thrust, eventually being discharged through the first conveying trough 18. The auger blades 19 provide comprehensive protection for the hydraulic oil in the cylinder groove 15, preventing inadequate hydraulic oil treatment in certain areas and resulting in a more uniform and thorough air bubble isolation effect.

[0045] Rubber strips 23 are installed on the side wall of the auger blade 19, and the rubber strips 23 are respectively attached to the inner walls of conveying trough 18 and conveying trough 22.

[0046] The rubber strip 23 is tightly fitted to the inner walls of conveying trough 18 and conveying trough 22. First, it fills the gap between the auger blade 19 and the inner wall of the trough, greatly enhancing the sealing between them. This prevents hydraulic oil from leaking through the gap during the process of being pushed by the auger blade 19, thus ensuring that the auger blade 19 can apply all its thrust to the hydraulic oil, improving the conveying efficiency of the hydraulic oil and the effect of air bubble separation. Second, as the auger blade 19 rotates, the rubber strip 23 will rub against the inner wall of the trough. This friction can clean the inner wall of the trough to a certain extent, scraping away impurities attached to the wall surface and preventing excessive accumulation of impurities from affecting the flow of hydraulic oil and the separation of air bubbles. In addition, the rubber strip 23 can also reduce the direct friction between the auger blade 19 and the inner wall of the trough, reducing component wear and extending the service life of the entire device, thus ensuring the stable operation of the air bubble isolation mechanical pump from multiple aspects.

[0047] The lower end of the conveying pipe 12 is fixed with the outlet pipe 11, and a valve is installed on the front end of the outer wall of the outlet pipe 11.

[0048] When the auger blades 19 rotate, they generate centrifugal force, collecting air bubbles in the hydraulic oil to the center. The air bubbles and a portion of the hydraulic oil are then discharged through the outlet pipe 11. The remaining purified hydraulic oil enters the delivery pipe 12. At this point, the outlet pipe 11 becomes a dedicated channel for the discharge of excess hydraulic oil and air bubbles, ensuring smooth discharge and preventing them from stagnating within the device and affecting subsequent bubble isolation. Simultaneously, the valve design allows operators to precisely control the discharge process. If the efficiency of the auger blades 19 in separating air bubbles changes, resulting in excessive or insufficient discharge of air bubbles and hydraulic oil, the opening and closing degree of the outlet pipe 11 can be controlled by adjusting the valve, thereby adjusting the discharge speed to match the entire separation process with the inflow rate of the hydraulic oil and maintaining pressure balance within the device.

[0049] The conveying groove 18 of conveying pipe 19 is vertically aligned with the conveying groove 22 of conveying pipe 212.

[0050] The centrifugal force generated by the rotation of the auger blades 19 needs to be evenly applied to the hydraulic oil to stably collect air bubbles to the center. Axial alignment ensures that the distance between each part of the auger blades 19 and the inner walls of the first and second conveying troughs 18 and 22 remains consistent during rotation, allowing the centrifugal force to be evenly distributed in the hydraulic oil and preventing poor bubble aggregation due to uneven force. If there is a misalignment of the axis, the centrifugal force may be too strong or too weak in certain areas during the rotation of the auger blades 19, causing air bubbles to disperse in the hydraulic oil and fail to gather to the center, thus preventing them from being discharged through the outlet pipe 11 via the preset path. Furthermore, axis alignment ensures a smooth flow path for the hydraulic oil between the first and second conveying troughs 18 and 22. Clean hydraulic oil pushed to the edge by centrifugal force can smoothly transition from the first conveying trough 18 to the second conveying trough 22 and then enter the mechanical pump body 1, without flow resistance caused by misalignment of the troughs. This ensures that the remaining hydraulic oil can enter the mechanical pump efficiently and stably, improving the overall operating efficiency of the device.

[0051] The mechanical pump body 1 has a fixed pipe 5 at the rear end and a fixed pipe 6 at the front end. The outer wall of the pipe 6 has a fixed mounting ring 13 at the front end and a fixed mounting ring 20 at the rear end of the outer wall of the pipe 7. The front end of the mounting ring 13 fits into the rear end of the mounting ring 20. The front end of the mounting ring 13 has a threaded hole 1 and the rear end of the mounting ring 20 has a threaded hole 2. The threaded holes 1 and 2 are connected by a bolt 14, and the rear end of the bolt 14 is threaded through a nut.

[0052] When the auger blades 19 rotate at high speed and generate centrifugal force, a certain amount of pressure and vibration will be generated inside the device. The tight fit between mounting ring 13 and mounting ring 20, along with the secure connection of bolts 14 and nuts, can effectively resist these pressures and vibrations, preventing loosening or leakage at the connection between pipe 26 and pipe 37. This ensures that after bubble separation, the remaining hydraulic oil can stably enter the mechanical pump body 1 through pipe 26, avoiding hydraulic oil loss or air mixing due to unstable connection, which would affect the working performance of the mechanical pump. At the same time, this detachable connection method facilitates the maintenance and repair of the device. When the auger blades 19 wear and affect the centrifugal force effect, or when it is necessary to clean the residual bubbles and impurities in the pipes, simply remove bolts 14 and nuts to separate pipe 26 from pipe 37, greatly reducing the difficulty of maintenance and ensuring that the device can maintain good bubble isolation performance for a long time.

[0053] The mechanical pump body 1 is fixed to the base 4 at the lower end. The base 4 is fixed to the front and rear ends of the positioning plate 3 respectively. Positioning holes are opened on both sides of the upper end of the positioning plate 3.

[0054] When the auger blades 19 rotate, they generate centrifugal force, inevitably causing the entire device to vibrate. The base 4 effectively disperses and absorbs this vibration, reducing its impact on the overall stability of the device. The positioning plate 3 securely fixes the device to the mounting surface through positioning holes, preventing displacement or shaking due to vibration. This ensures that the auger blades 19 remain in the preset position, guaranteeing stable direction and magnitude of centrifugal force, thereby accurately collecting air bubbles to the center and discharging them through the outlet pipe 11. If the device's stability is insufficient, the rotation trajectory of the auger blades 19 will deviate, the distribution of centrifugal force will become uneven, and air bubbles may not be able to gather and discharge smoothly, thus affecting the purity and efficiency of the remaining hydraulic oil entering the mechanical pump body 1. Furthermore, a stable mounting structure reduces friction and wear between components, extending the service life of key components such as the auger blades 19 and pipelines, ensuring long-term stable operation of the entire device, and providing a continuous supply of clean hydraulic oil to the hydraulic system.

[0055] In this embodiment, when a mechanical pump is needed to transport hydraulic oil, the hydraulic oil is first introduced into the cylinder groove 15 inside the cylinder 8 through the pipe 4 10. The pipe 4 10 serves as the first gate for the hydraulic oil to enter the device. Its fixed connection with the cylinder 8 ensures that the hydraulic oil can flow into the cylinder groove 15 stably and continuously, providing sufficient processing material for the subsequent bubble separation work.

[0056] Subsequently, motor 2 is started. The drive end of motor 2 drives the auger blade 19 to rotate through the circular hole 17 at the upper end of the conveying pipe 9. The rotation of the auger blade 19 is the core power source for the entire bubble separation process. It not only undertakes the task of conveying hydraulic oil, but more importantly, it collects bubbles through the centrifugal force generated by the rotation. Under the action of the auger blade 19, the hydraulic oil in the cylinder trough 15 rotates accordingly. During the rotation, the bubbles in the hydraulic oil gradually gather towards the center under the action of centrifugal force, which is the location of the auger blade 19. This effectively concentrates the bubbles that were originally dispersed in the hydraulic oil, preparing them for subsequent discharge.

[0057] Because the conveying groove 18 of the conveying pipe 19 and the conveying groove 22 of the conveying pipe 212 are vertically aligned, the auger blades 19 can maintain a stable posture when rotating. The distance between each part of the blades and the inner walls of the conveying grooves 18 and 22 is uniform, ensuring that centrifugal force can be applied evenly to the hydraulic oil flow, allowing air bubbles to consistently gather towards the center and not disperse due to uneven force. At the same time, this axial alignment design also ensures a smooth transition of hydraulic oil flow between the conveying grooves. Air bubble-free hydraulic oil pushed to the edge by centrifugal force can smoothly enter the conveying groove 22 from the conveying groove 18 and then flow to the mechanical pump body 1.

[0058] As the auger blades 19 rotate, they transport the collected air bubbles upwards, through the first conveying trough 18 and the cylindrical trough 15, and finally into the second conveying trough 22. The outlet pipe 11, fixed at the lower end of the second conveying trough 22, then functions, allowing the air bubbles and some hydraulic oil to be discharged through it. The valve at the front end of the outer wall of the outlet pipe 11 can be adjusted to control the discharge speed, ensuring that the air bubbles and some hydraulic oil are discharged promptly and do not stagnate in the second conveying trough 22. This also prevents excessive discharge from affecting the amount of hydraulic oil entering the mechanical pump body 1.

[0059] After bubble separation, the remaining hydraulic oil, which contains no bubbles or very few bubbles, enters the mechanical pump body 1 through pipe 3 (7) and pipe 2 (6). Pipe 2 (6) and pipe 3 (7) are tightly connected by mounting ring 1 (13), mounting ring 2 (20), bolt 14, and nut, ensuring that the hydraulic oil flow will not leak during transportation and will not mix with new air to generate bubbles, thus ensuring that the hydraulic oil entering the mechanical pump body 1 is clean and stable.

[0060] Throughout the entire process, from the introduction of hydraulic oil to the separation and removal of air bubbles, and then to the entry of clean hydraulic oil into the mechanical pump, each component is interconnected and fully utilizes its respective role to form an organic whole. This efficiently removes air bubbles from the conveyed hydraulic oil, providing a reliable guarantee for the safe operation of the mechanical pump.

[0061] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
