液壓機是如何工作的，是利用什么工作的

液壓機所用的工作介質的作用不僅是傳遞壓強，而且保證機器工作部件工作靈敏、可靠、壽命長和泄漏少。

液壓機的原理是電機帶動液壓泵產壓力驅動液壓油缸下壓或上頂來實現您所需要的作用，

液壓泵是液壓系統的動力源，

靠泵的作用力使液壓油通過液壓管路進入油缸/活塞

然后油缸/活塞里有幾組互相配合的密封件，使液壓油不泄露。

通過單向閥使液壓油在油箱循環使油缸/活塞循環做功。這就是簡單的液壓系統了。

通常指液壓泵和液壓馬達，液壓泵和液壓馬達都是液壓系統中的能量轉換裝置，不同的是液壓泵把驅動電動機的機械能轉換成油液的壓力能，是液壓系統中的動力裝置，而液壓馬達是液壓系統中的執行裝置。把油液的壓力能轉換成機械能.

大部分液壓泵和液壓馬達是互逆的，即輸入壓力油，液壓泵就變成液壓馬達，就可輸出轉速和轉矩，但在結構上，還是有差異的。

液壓機液壓系統中常用的液壓泵和液壓馬達都是容積式的，其工作原理都是利用密封容積的變化進行吸油和壓油的。

液壓機液壓系統是濾芯管路和各種閥體組成的，要有一個液壓泵提供壓力，一個溢流閥防止系統壓力過高及時卸荷。換向閥控制液壓缸油液的流向來控制液壓缸的伸縮。

另外還有很多如減壓閥節流閥等等是根據工作需要選擇的，了解更多，可以參考各種基本閥體的工作原理和實現功效，會更方便理解。機械上多是組合閥，不同的閥體組合在一起實現功效，挺復雜，其實也無非是兩種控制一種是壓力控制閥芯的開啟，一種是電磁產生磁力控制閥芯的開啟。

The working medium used in hydraulic press is not only to transmit pressure, but also to ensure that the working parts of the machine work sensitively, reliably, with long service life and less leakage.

The principle of the hydraulic press is that the motor drives the hydraulic pump to produce pressure and drives the hydraulic cylinder to press down or top up to realize the function you need,

The hydraulic pump is the power source of the hydraulic system,

The force of the pump causes the hydraulic oil to enter the cylinder / piston through the hydraulic pipeline

Then there are several sets of matched seals in the cylinder / piston to keep the hydraulic oil from leaking.

The hydraulic oil is circulated in the oil tank by one-way valve to make the cylinder / piston cycle work. This is a simple hydraulic system.

Usually refers to the hydraulic pump and hydraulic motor, hydraulic pump and hydraulic motor are energy conversion devices in the hydraulic system, the difference is that the hydraulic pump converts the mechanical energy of the driving motor into the pressure energy of the oil, which is the power device in the hydraulic system, and the hydraulic motor is the Executive device in the hydraulic system. Convert the pressure energy of oil into mechanical energy

Most of the hydraulic pumps and hydraulic motors are reciprocal, that is to say, the input pressure oil, the hydraulic pump becomes a hydraulic motor, which can output speed and torque, but there are differences in structure.

The hydraulic pump and motor commonly used in the hydraulic system of hydraulic press are volume type, and their working principle is to absorb and press oil by using the change of sealed volume.

The hydraulic system of hydraulic press is composed of filter element pipeline and various valve bodies. There should be a hydraulic pump to provide pressure and an overflow valve to prevent the system pressure from being too high and unloading in time. The directional valve controls the flow direction of the hydraulic cylinder oil to control the expansion and contraction of the hydraulic cylinder.

In addition, there are many, such as pressure reducing valve and throttle valve, which are selected according to the work needs. To learn more, you can refer to the working principle and realization effect of various basic valve bodies, which will be more convenient to understand. Most of them are combination valves. It is very complicated to combine different valve bodies to achieve the effect. In fact, there are only two kinds of control, one is the opening of pressure control valve core, the other is the opening of electromagnetic magnetic force control valve core.
