小型液压机液压系统课程设计

据南通液压机厂家（www.jsteang.com）报道：巨型四柱液压机的液压系统，从目前来看以及从专业角度来讲，其是有两个独立的子系统，即为驱动系统和同步纠偏系统，并且这两个系统是分别设置为两大液压站。因此，基于上述，这个问题的答案是为两个子系统，而且是为两个相互独立的子系统。

液压机液压传动体系具有体积小、重量轻、功率大、运转平稳、可无级调速等优点，在各种起重机上得到广泛应用。但液压传动体系的传动功率低于其他传动体系，易发生毛病且毛病的剖析和扫除比较困难。

The hydraulic transmission system of hydraulic press has the advantages of small volume, light weight, large power, smooth operation and stepless speed regulation, which are widely used in various cranes. However, the transmission power of hydraulic transmission system is lower than that of other transmission systems.

液压机小型液压机液压系统课程设计液压体系的走漏原因首要有两种，固定密封处走漏和运动密封处走漏，固定密封处走漏的部位首要包括缸底、各管接头的衔接处等，运动密封处首要包括油缸活塞杆部位、多路阀阀杆等部位。从油液的走漏上也可分为外走漏和内走漏，外走漏首要是指液压油从体系走漏到环境中，内走漏是指因为高低压侧的压力差的存在以及密封件失效等原因，使液压油在体系内部由高压侧流向低压侧。

There are two main reasons for the leakage of hydraulic system of hydraulic press, the leakage of the fixed seal and the leakage of the movement seal, the leakage of the fixed seal first including the bottom of the cylinder, the joint of the pipe joint, the movement seal first including the cylinder piston rod, multi-way valve stem and other parts. From the leakage of oil can also be divided into external leakage and internal leakage, external leakage mainly refers to the hydraulic oil leakage from the system to the environment, internal leakage refers to the existence of pressure difference between the high and low pressure side and seal failure, so that the hydraulic oil in the system from the high pressure side to the low pressure side.

四柱液压机的主缸，其想要避免升不起来这一问题的话，是需要从以下这几个方面来着手进行，是为继电器、液压机油压以及液压机中的快慢行程开关，当这三个保证没有问题后，才可以避免上述这一问题，进而，来保证四柱液压机能正常运行和使用。
