What is a hydraulic oil pump
The hydraulic oil pump is the core component of the hydraulic system. It is mainly used to convert mechanical energy into hydraulic energy to provide power for the system. It is widely used in engineering machinery, agricultural equipment, aerospace and other fields. This article will give a structured introduction to the definition, classification, working principles and market trends of hydraulic oil pumps based on recent hot topics.
1. Definition and function of hydraulic oil pump
The hydraulic oil pump generates pressure through mechanical movement (such as the rotation of gears, vanes, or plungers), pushing hydraulic oil to circulate in the system, thereby driving the actuator (such as a hydraulic cylinder or motor) to work. Its core features include:
| Function | illustrate |
|---|---|
| energy conversion | Convert mechanical energy from an engine or motor into hydraulic energy |
| pressure provided | Provide stable flow and pressure of oil to the system |
| System control | Actuator speed control by adjusting flow |
2. Main classification of hydraulic oil pumps
According to the structure and working principle, hydraulic oil pumps can be divided into the following three categories:
| type | Features | Application scenarios |
|---|---|---|
| gear pump | Simple structure, low cost, but low efficiency | Small construction machinery and agricultural equipment |
| vane pump | Low noise, uniform flow, medium pressure | Machine tools, injection molding machines |
| plunger pump | High pressure, high efficiency, complex structure | Aerospace, heavy machinery |
3. Recent hot topics and market trends
