EFFICIENT SPEED CONTROL SYSTEM INCORPORATING HYDRAULIC ACTUATORS AND SOLENOID VALVES

Abstract

Water was historically used as a power source for certain applications, but it lacked the necessary properties for hydraulic pumps and cylinders, leading to the adoption of non-corrosive oil as a more suitable material. The control of hydraulic mechanisms and mechanical conveyance has become crucial in modern applications, particularly in complex and dynamic engineering systems. Simulation through computer programs has emerged as a vital tool for studying and designing such systems, allowing for thorough analysis and experimentation prior to manufacturing. Simulation finds applications in various fields, including natural resources, manufacturing processes, healthcare, military industries, computer system analysis, transportation, and reverse engineering. The market offers a wide range of simulation software packages, each with different features, modeling approaches, techniques, and cost efficiency. Choosing the appropriate package for specific applications requires expertise and careful evaluation.

In manufacturing, two main categories of hydraulic transmission circuits are commonly employed: those controlled by valves and those controlled by pumps. Valve-based circuits utilize hydraulic valves as controllers, while a hydraulic pump maintains a steady flow rate. These circuits are extensively used in industries due to their high performance. On the other hand, pump-controlled circuits directly connect a hydraulic pump to a hydraulic motor, with the pump serving the dual role of generating hydraulic pressure and flow, as well as controlling the motor. Figure 1 illustrates a typical hydraulic circuit controlled by a valve.
