Hydraulic presses are varied in terms of type and technical specifications. This variety in hydraulic structures and systems, as well as automation and technical specifications such as appearance, table dimensions, force, speed, success and performance, cause the structure of hydraulic presses in different models and applications.
Design and analysis of hydraulic circuits is one of the techniques that requires a deep knowledge and complete understanding of hydraulic components and elements. The designer designs the suitable hydraulic circuit based on his knowledge about the function of different elements and how they connect to the requirements of the appropriate system. Typically, for a particular function, several hydraulic circuits can make a set of connected components carrying a hydraulic fluid to the consumer.
PM is the abbreviation for maintenance and repairing (Preventive maintenance). Of course, over time, there have been several reforms in this field, including the use of predictive rather than preventive.
After invention of transistors and integrated circuits (ICs), and with the rapid advancement of computer science and technology, the design and implementation of hardware is possible through programmable software, which allowed the action for commands of each person in the relevant circuit.
