HYDRAULIC SYSTEMS

The customer was tasked to develop and implement a hydraulic press control system.

Algorithm of operation - after starting the system with the "Start" button, the press should start moving downwards within a certain time interval. After that, start moving in the opposite direction. When you reach the starting point, the hydraulic press must stop. The system must be restarted with the "Start" button. The system must provide for an emergency stop of the process with the "Stop" button, as well as in emergency cases - when the shield door is open, or the hydraulic press engine is overloaded. In the event of an emergency, the "Emergency" indicator light should illuminate. The interval of the complete cycle and the lowering process must be adjustable.

A contactor is used to control the operation of the engine, and a motor protection device is used to protect the engine from overload. A limit switch is used for emergency shutdown of the system in case of opening the shield door. The full cycle time and the lowering time of the hydraulic press are regulated by a time relay. The lowering / raising of the hydraulic press is controlled by means of a hydraulic distributor.

This system involves the use of motors of different capacities with the appropriate selection of automatic motor protection and contactor.
