Description

Technical Field

[0001] This utility model relates to the field of liquid-driven booster pump technology, specifically to an oil passage block structure for a liquid-driven booster pump. Background Technology

[0002] The hydraulic booster pump is powered by an external high-pressure medium. After the high-pressure medium drives the pump, it flows back to the oil tank through the return port. Therefore, the hydraulic booster pump needs to be connected to the external high-pressure pipe and the return pipe through interfaces. In the existing technology, two interfaces are usually set directly on the pump body, and the connection to the pipeline is achieved through a connector. However, this structure has inherent defects: the position and direction of the interfaces on the pump body are fixed, while the design scenarios of mechanical equipment are complex and varied. On-site installation is often difficult due to limited installation space or interference from the pipe direction. Additional structural components need to be modified to adapt to the installation requirements, which not only increases the installation cost and time, but also affects the versatility and efficiency of equipment installation, and cannot meet the needs of mass production and diversified installation scenarios.

[0003] To address the shortcomings of the existing technology, this utility model proposes an oil passage block structure for a hydraulic booster pump. By optimizing the structural design of the oil passage block, multi-directional and multi-form oil passage connections are achieved, solving the problem of poor adaptability of existing installation structures. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing liquid-driven booster pumps, which have poor installation adaptability due to fixed interfaces, and to provide an oil circuit block structure that can realize multi-directional and multi-form oil circuit connections, adapt to different installation spaces and orientation requirements, and is reliable and easy to mass-produce.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: An oil manifold structure for a hydraulically driven booster pump includes an oil manifold block, a pump body, oil port one, oil port two, oil port three, oil port four, a mounting plane, a fixing through hole, a screw positioning step, an oil passage hole, a sealing step, and a fixing screw; wherein: The oil passage block is equipped with oil port 1, oil port 2, oil port 3 and oil port 4. The oil passage block has two independent oil passages inside. One oil passage is connected to oil port 1 and oil port 2 to form the first set of independent oil passages. The other oil passage is connected to oil port 3 and oil port 4 to form the second set of independent oil passages. The first set of independent oil passages and the second set of independent oil passages are not connected to each other. Each of the four oil ports (oil port 1, oil port 2, oil port 3, and oil port 4) is provided with a corresponding mounting surface. The four oil ports and their corresponding mounting surfaces are formed by one-time clamping and machining to ensure the perpendicularity of the oil ports to the mounting surfaces. The oil passage block has four fixed through holes and corresponding screw positioning steps. The four fixed through holes are arranged in a "three holes in a row" pattern, with an additional fixed through hole in the middle near the oil port. The pump body has two rows of "three holes in a row" threaded holes at corresponding positions. The fixing screw passes through the fixed through holes and the screw positioning steps and engages with the threaded holes on the pump body to achieve detachable fixing of the oil passage block and the pump body. After the oil passage block is rotated 180°, it can be reliably fixed to the pump body through the other row of threaded holes. A sealing step is provided at each of the two oil passage holes. After the oil passage block and the pump body are installed and fixed, the sealing step forms a sealing groove. A sealing ring is installed in the sealing groove to seal the gap between the oil passage block and the pump body. The oil circuit block has two installation postures: front-facing and rear-facing. Both postures have two connection methods: a combination of horizontal and vertical connection directions or both horizontal and vertical connection directions. Except for the oil port connected to the pipeline, the remaining unused oil ports are sealed with plugs.

[0006] Compared with the prior art, the beneficial effects of this utility model are: 1. Strong adaptability, solving installation interference problems: This utility model integrates four oil ports and sets two sets of independent oil channels on the oil manifold block. With the 180° rotation installation function of the oil manifold block and the selection of multiple directions of pipe connection, the oil manifold block has two installation postures: forward and backward. In each posture, four oil port combination methods can be realized, which can adapt to different installation spaces and pipe connection direction requirements, effectively avoid installation interference, and complete on-site installation without changing structural components. 2. High installation accuracy and reliable sealing: The four oil ports are machined in one clamping process with the corresponding mounting plane, ensuring the absolute perpendicularity of the oil ports to the mounting plane and improving the accuracy of pipeline connection; at the same time, the sealing groove is formed by the sealing step and the sealing ring is installed to achieve a reliable seal between the oil passage block and the pump body, avoiding leakage of high pressure medium; 3. Compact structure and strong versatility: The oil circuit block is small in size and has a reasonable structural design, which can be adapted to most models of hydraulic booster water pumps, making it easy to mass-produce and reduce production and manufacturing costs; and it adopts a detachable bolt fixing method, which makes installation and disassembly convenient and facilitates later maintenance.

[0009] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0010] like Figure 1 , 6 As shown, this embodiment provides an oil manifold structure for a liquid-driven booster pump, including an oil manifold block 1, a pump body 2, an oil port 1 3, an oil port 2 4, an oil port 3 5, an oil port 4 6, a mounting plane 7, a fixing through hole 8, a screw positioning step 9, an oil passage hole 11, a sealing step 12, and a fixing screw 13.

[0011] The specific structural design is as follows: The oil passage block 1 is an integrated molding structure, on which oil port 1 3, oil port 2 4, oil port 3 5 and oil port 4 6 are integrated and machined. All four oil ports adopt a standardized interface design, which is convenient for matching with pipeline connectors. The oil passage block 1 has two independent oil passage holes 11 drilled inside. The diameter of the oil passage hole 11 is designed according to the rated flow of the hydraulic booster pump. The two ends of one oil passage hole 11 are respectively connected to oil port 1 3 and oil port 2 4 to form the first set of independent oil passages for high pressure medium input. The two ends of the other oil passage hole 11 are respectively connected to oil port 3 5 and oil port 4 6 to form the second set of independent oil passages for medium return. The two sets of oil passages are not connected to each other to avoid mixing of high pressure medium and return medium.

[0012] The ends of oil port 1 (3), oil port 2 (4), oil port 3 (5), and oil port 4 (6) are respectively machined with mounting planes 7. During machining, a single clamping and positioning is used to simultaneously complete the machining of the four oil ports and their corresponding mounting planes 7, ensuring that the axis of each oil port is perpendicular to the mounting plane 7, with the error controlled within 0.02mm. This ensures the fit between the pipeline joint and the oil manifold block 1 after installation and improves the sealing performance.

[0013] Four fixing through holes 8 are machined at the edge of the oil manifold 1, arranged in a "three holes per row" pattern. An additional fixing through hole 8 is added in the middle of the area near the oil inlet to enhance the stability of the connection between the oil manifold 1 and the pump body 2. Each fixing through hole 8 has a screw positioning step 9 machined on its inner side to position the fixing screw 13 and prevent screw misalignment during fixing. Correspondingly, the end face of the pump body 2 that mates with the oil manifold 1 has two rows of "three holes per row" threaded holes. The two rows of threaded holes are symmetrical about the central axis of the pump body 2. When the oil manifold 1 is installed in the forward direction, the fixing screw 13 passes through the fixing through holes 8 and the screw positioning step 9 and is threadedly connected to the first row of threaded holes. When the installation direction needs to be adjusted, the oil manifold 1 is rotated 180°, and the fixing screw 13 can be fixed by engaging with the second row of threaded holes, achieving bidirectional installation adaptation of the oil manifold 1.

[0014] Both oil passages 11 have a sealing step 12 machined at one end near the pump body 2. The sealing step 12 has a U-shaped cross section. When the oil passage block 1 is attached and fixed to the pump body 2, the sealing step 12 and the end face of the pump body 2 form a sealing groove. An O-ring is installed in the sealing groove. The O-ring is made of high-pressure resistant rubber to ensure reliable sealing under high-pressure medium and prevent medium leakage from the joint between the oil passage block 1 and the pump body 2.

[0015] In actual installation, the installation posture and connection method of the oil passage block structure in this embodiment can be selected according to the size of the site space and the requirements of the connection direction: 1. Rear-facing installation posture: Oil port 1-3 horizontal connector or oil port 3-5 vertical connector can be selected. Figure 3 ), or oil port 2.4 vertical connector, oil port 4.6 horizontal connector ( Figure 4 Alternatively, oil port 1 (3) and oil port 2 (4) can be connected to the same horizontal pipe, and oil port 3 (5) and oil port 4 (6) can be connected to the same vertical pipe. Unused oil ports are sealed with metal plugs. 2. Forward installation orientation: Optionally, a vertical connecting pipe with port 1-3 or a horizontal connecting pipe with port 3-5 can be selected. Figure 5 ), or oil port 2 4 horizontal connector, oil port 4 6 vertical connector ( Figure 6 Similarly, you can choose the same horizontal or vertical pipe combination, and seal the unused oil port with a plug.

[0016] Through the above structural design, the oil manifold block structure of this embodiment can achieve eight different installation combinations, fully adapting to various complex on-site installation scenarios. No additional processing or modification of the pump body or oil manifold block is required, effectively improving installation efficiency and reducing installation costs. At the same time, the structure is small in size and light in weight, compatible with most existing models of hydraulically driven booster pumps, facilitating mass production and widespread application.

[0017] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
