Technical Field

[0001] This utility model belongs to the field of hydraulic power equipment technology, specifically a high-pressure silent oil source. Background Technology

[0002] In industrial production, hydraulic systems, as important power transmission and control devices, are widely used in various types of mechanical equipment. The hydraulic oil source, as the power core of the hydraulic system, directly affects the overall operational performance of the system.

[0003] However, traditional hydraulic power sources have many problems and cannot meet the needs of modern industry. Firstly, noise is a significant issue. The motor and pump units of traditional power sources are poorly designed, generating considerable mechanical and fluid noise during operation. This not only harms the health of operators but also pollutes the working environment, with even greater impacts in noise-sensitive locations such as precision machining workshops. Secondly, pressure stability is poor. Affected by load changes and flow fluctuations, the output pressure of traditional power sources fluctuates greatly, reducing the working accuracy and stability of hydraulic actuators, especially affecting high-precision equipment such as precision CNC machine tools. Thirdly, energy consumption is high. The low energy conversion efficiency of motors and pump units often results in an "oversized motor for a small load" phenomenon, leading to energy waste, contradicting energy conservation and emission reduction trends, and increasing enterprise costs. Additionally, filtration accuracy is insufficient. Traditional filtration devices struggle to remove minute impurities, accelerating component wear, shortening equipment lifespan, leading to frequent failures and high maintenance costs. Furthermore, traditional power sources lack ease of operation and intelligence; pressure regulation is mostly manual, with low precision and cumbersome processes, and some pipeline connections have poor reliability and are prone to leakage.

[0004] Therefore, a high-pressure silent oil source is proposed to address the above problems. Utility Model Content

[0009] Preferably, the substation is equipped with a precision high-pressure filter assembly, an accumulator, a multi-channel digital intelligent voltage regulation module, and an anti-interference unidirectional circuit.

[0010] Preferably, the inlet and outlet of the substation splitter are equipped with Parker high-pressure ball valves and quick-connect couplings, and the split pressure can be independently adjusted by a digital intelligent pressure regulating module.

[0011] Preferably, the piping assembly is made of SUS stainless steel high-pressure precision tubing, the inner wall of the tubing is honed, and the joints are machined by a machine tool and then welded using laser and argon arc welding processes.

[0012] Preferably, the main oil source pressure, the secondary pressure regulation of the substation, and the pressure reduction of the branch circuit can all be implemented in a digital intelligent pressure regulation module on the HMI interface.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figures 1 to 4 As shown, this utility model provides a high-pressure silent oil source, including a device body. The device body contains an oil source main body 1 and a substation 2. The oil source main body 1 is located inside the lower part of the device body, and the substation 2 is installed on the upper surface of the oil source main body 1. The oil source main body 1 and the substation 2 are connected by a pipeline assembly 3. The device body is the installation foundation and shell of the entire high-pressure silent oil source, and it houses the oil source main body 1 and the substation 2, providing protection and support for the internal components.

[0022] The main oil source 1 is located inside the lower part of the device body and is the core component that provides hydraulic power. It is equipped with six oil-immersed motor high-pressure pump sets 11. These oil-immersed motor high-pressure pump sets 11 are characterized by quiet operation, high pressure, stable pressure, and energy saving, and can stably provide high-pressure hydraulic oil to the entire system.

[0023] Each oil-immersed high-pressure pump unit 11 is equipped with a safety valve 111 and an electromagnetic clutch 112 at its outlet. The safety valve 111 is installed at one end of the connecting pipe on the outlet of the oil-immersed high-pressure pump unit 11. Its main function is to automatically open and release pressure when the system pressure exceeds a specified value, protecting the system from damage caused by excessive pressure and ensuring safe system operation. The electromagnetic clutch 112 is installed on one side of the safety valve 111. It uses electromagnetic control to connect and disconnect the pump unit from the power source, facilitating the control and adjustment of the pump unit to adapt to different operating requirements.

[0024] like Figures 1 to 4As shown, substation 2 is installed on the upper surface of the oil source body 1 and connected to the oil source body 1 through pipeline assembly 3. It undertakes functions such as hydraulic oil filtration, energy storage, pressure regulation, and circuit control. Substation 2 is equipped with a precision high-pressure filter assembly 21, an accumulator 22, a multi-channel digital intelligent pressure regulating module 23, and an anti-interference unidirectional circuit 24. The precision high-pressure filter assembly 21 can effectively filter impurities in the hydraulic oil, ensuring the cleanliness of the hydraulic oil, reducing system failures, and extending the service life of the equipment; the accumulator 22 can store hydraulic energy and release it when the system needs it, playing a role in stabilizing the system pressure and absorbing pressure pulsations; the multi-channel digital intelligent pressure regulating module 23 can achieve precise pressure regulation of different circuits to meet the different pressure requirements of various parts of the system; the anti-interference unidirectional circuit 24 can prevent hydraulic oil from interfering with each other between different circuits, ensuring that each circuit works independently and stably.

[0025] In addition, both the inlet and outlet of the substation 2 splitter are equipped with Parker high-pressure ball valves 25 and quick-connect couplings 26. The Parker high-pressure ball valves 25 have excellent sealing and pressure resistance, effectively controlling the flow of hydraulic oil; the quick-connect couplings 26 facilitate quick connection and disconnection of pipelines, making equipment installation, maintenance, and repair convenient. Furthermore, the branch pressure can be independently and intelligently adjusted digitally, further improving the system's flexibility and adaptability.

[0026] Piping assembly 3 uses SUS304 stainless steel high-pressure precision tubing. This material has excellent corrosion resistance, high strength, and high toughness, and can withstand the impact and corrosion of high-pressure hydraulic oil. The inner wall of the tubing is honed to make it smooth and flat, reducing the resistance and pressure loss of hydraulic oil during flow and improving system efficiency. The joints are machined using laser and argon arc welding processes, ensuring the precision and strength of the joints, guaranteeing the sealing and reliability of the pipeline connection, avoiding problems such as hydraulic oil leakage, and ensuring optimal flow rate under high pressure and high flow conditions.

[0027] HMI Interface 4 is a crucial window for human-machine interaction. Digital intelligent pressure regulation can be achieved through this interface for main oil pressure, secondary pressure regulation at the substation, and pressure reduction at the branch circuit breaker. Operators can intuitively understand the system's pressure parameters via HMI Interface 4 and make convenient and precise adjustments according to actual needs. The operation is simple and easy to understand, improving system controllability and operational efficiency.

[0028] Working principle and process: The operator issues a start command through the HMI interface 4, and the system begins initialization. At this time, the oil-immersed high-pressure pump unit 11 in the oil source body 1 engages with the power source under the action of the electromagnetic clutch 112 and begins to operate. The six oil-immersed high-pressure pump units 11 start up step by step according to the preset program to avoid the impact of excessive instantaneous load on the system. After the oil-immersed high-pressure pump units 11 are running, they draw hydraulic oil from the oil tank and pressurize it to form high-pressure hydraulic oil. The high-pressure hydraulic oil flows out through the pipeline at the pump unit outlet. At this time, the safety valve 111 is in the closed state to monitor the system pressure and ensure that the initial pressure is within the normal range.

[0029] High-pressure hydraulic oil enters pipeline assembly 3. Because the pipeline uses SUS304 stainless steel high-pressure precision tubing, and the inner wall of the tubing is honed, the hydraulic oil flows smoothly within the pipeline with minimal resistance and pressure loss. Simultaneously, laser and argon arc welding processes ensure the sealing of the pipeline connections, preventing hydraulic oil leakage. The high-pressure hydraulic oil is stably delivered to substation 2 for filtration. The high-pressure hydraulic oil first enters the precision high-pressure filter assembly 21 in substation 2, where impurities are removed by the filter device, ensuring that the cleanliness of the hydraulic oil entering subsequent stages meets requirements and reducing wear on downstream components. A portion of the filtered hydraulic oil enters accumulator 22, which stores a certain amount of hydraulic energy. When system pressure fluctuates, the stored energy is released to stabilize the system pressure and absorb pressure pulsations. The treated hydraulic oil then enters anti-interference unidirectional circuit 24 to prevent mutual interference between different circuits. Subsequently, hydraulic oil flows through a distributor. Parker high-pressure ball valves 25 at the distributor's inlet and outlet control the on / off of each branch, and the hydraulic oil is connected to external equipment via quick-connect couplings 26 to achieve branched output. Throughout the operation, the operator can digitally and intelligently adjust the main oil pressure, substation secondary pressure regulation, and distributor pressure reduction via the HMI interface 4. When pressure adjustment is needed, the command is transmitted through the system to the corresponding pressure regulating components. Components such as the multi-channel digital intelligent pressure regulating module 23 respond to the command, changing the hydraulic oil pressure to meet the working requirements of different external equipment. Simultaneously, the safety valve 111 continuously monitors the system pressure. If the pressure exceeds the specified value, it automatically opens to release pressure and protect the system. When work is finished or shutdown is required, the operator issues a stop command via the HMI interface 4. The electromagnetic clutch 112 disengages, the oil-immersed motor high-pressure pump unit 11 stops operating, and no longer outputs high-pressure hydraulic oil. The Parker high-pressure ball valves 25 close, cutting off the hydraulic oil supply to each branch, and the system gradually depressurizes, completing the entire workflow.
