液压机是如何工作的,是利用什么工作的

液压机所用的工作介质的作用不仅是传递压强,而且保证机器工作部件工作灵敏、可靠、寿命长和泄漏少。

液压机的原理是电机带动液压泵产压力驱动液压油缸下压或上顶来实现您所需要的作用,

液压泵是液压系统的动力源,

靠泵的作用力使液压油通过液压管路进入油缸/活塞

然后油缸/活塞里有几组互相配合的密封件,使液压油不泄露。

通过单向阀使液压油在油箱循环使油缸/活塞循环做功。这就是简单的液压系统了。

 

通常指液压泵和液压马达,液压泵和液压马达都是液压系统中的能量转换装置,不同的是液压泵把驱动电动机的机械能转换成油液的压力能,是液压系统中的动力装置,而液压马达是液压系统中的执行装置。把油液的压力能转换成机械能.

大部分液压泵和液压马达是互逆的,即输入压力油,液压泵就变成液压马达,就可输出转速和转矩,但在结构上,还是有差异的。

液压机液压系统中常用的液压泵和液压马达都是容积式的,其工作原理都是利用密封容积的变化进行吸油和压油的。

 

液压机液压系统是滤芯管路和各种阀体组成的,要有一个液压泵提供压力,一个溢流阀防止系统压力过高及时卸荷。换向阀控制液压缸油液的流向来控制液压缸的伸缩。

另外还有很多如减压阀节流阀等等是根据工作需要选择的,了解更多,可以参考各种基本阀体的工作原理和实现功效,会更方便理解。机械上多是组合阀,不同的阀体组合在一起实现功效,挺复杂,其实也无非是两种控制一种是压力控制阀芯的开启,一种是电磁产生磁力控制阀芯的开启。

 

 

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.
