ABSTRACT

As one of the modern mechanical equipment to achieve an important technical means of power transmission and control, hydraulic technology has been widely applied in various fields of the national economy. Compared with other drive control technology, hydraulic technology with high energy density, convenient and flexible configuration, wide range of speed regulation, smooth and fast is good, easy to control and overload protection, easy to realize automation and electromechanical integration, system design and manufacture and use and maintenance is convenient wait for a variety of significant technical advantages, which make it become the basic constitution the technology of modern mechanical engineering and modern control engineering of the basic elements of technology.
The main content of this paper is the design and PLC design of special drilling machine hydraulic system. The design of the hydraulic system is a part of the whole design of the machine, it is the task of the application of the machine, according to the characteristics and requirements, using the basic principles of hydraulic transmission, and draw up a reasonable hydraulic system diagram, and then through the necessary calculations to determine the parameters of hydraulic system, structure design and then according to these parameters to the selection of hydraulic components of the specification and the last, checking the main performance of the hydraulic system.
Keywords: special drill press; hydraulic system; PLC design
