Description

Technical Field

[0001] This utility model relates to the field of hydraulic oil source technology, specifically to a high-pressure, high-flow oil source. Background Technology

[0002] The hydraulic oil source, as the core power unit of hydraulic transmission and servo control systems, mainly consists of components such as a motor, hydraulic pump, oil tank, oil filter, and control valve. Its function is to provide stable flow and pressure output for the system's actuators and to precisely control the pressure, temperature, and cleanliness of the hydraulic medium. This is especially important as industrial equipment develops towards higher pressure, larger flow, and greater intelligence.

[0003] For example, a high-flow hydraulic oil source, with application number CN202421062038.7 and authorization announcement date of 20250207, includes an oil tank body. A control cabinet is fixedly installed on the right side of the top of the oil tank body. Multiple oil pump motors are fixedly installed on the top of the oil tank body and to the left of the control cabinet. An mounting base is fixedly installed below the oil tank body. A buffer assembly is fixedly installed between the mounting base and the oil tank body. A cooling water tank is fixedly installed on the right side of the oil tank body. A cooling coil is fixedly installed at the bottom inside the oil tank body. A liquid level window is provided at the left side of the front of the oil tank body. Multiple cleaning covers are fixedly installed on the front of the oil tank body. An oil drain pipe is fixedly connected to the bottom of the front of the oil tank body. Compared with existing high-flow hydraulic oil sources, this utility model can improve the overall stability, safety, and heat dissipation effect of the high-flow hydraulic oil source through design.

[0004] The hydraulic oil sources mentioned above and those used in existing technologies still employ the traditional external oil pump layout, which fails to solve core issues such as high-pressure pulsation suppression, multi-stage intelligent pressure regulation, and modular integration. Furthermore, they do not introduce an active pollution control mechanism, making it difficult to meet the needs of precision industrial scenarios. Therefore, it is urgent to design a high-pressure, high-flow oil source to solve the above problems. Utility Model Content
