Laboratory for Hydraulic and Pneumatic Systems
Head: Assist. Prof. Goran Gregov, D. Sc. M. E.
Areas of Interest:
Measurement of hydraulic system parameters.
Analysis of hydraulic motor parameters with laboratory brake loading system.
Measurement of pneumatic system parameters.
Analysis of servo-pneumatic system parameters.
Laboratory Brake Loading System
The laboratory brake loading system is used to load test hydraulic motors. The electromagnetic brake Telma AD 50-90 is used to achieve variable loading torque. The hydraulic motor and electromagnetic brake are connected by a rigid coupling, and the test bench is adjustable, allowing different types of hydraulic motor to be tested. The hydraulic power unit Hansa-Flex with several directional control valves operated by a PLC unit is used to drive the hydraulic motor. The laboratory system also consists of measuring equipment for motor load torque, rotational speed and hydraulic motor oil pressure drop.
Technical specifications:
Max. load moment: 900 Nm @ 1000 min-1
Max. brake rotational speed: 4500 min-1
Max. pump flow rate: 15 l/min
Max. oil pressure: 210 bar
Laboratory Pneumatic Testing System
The laboratory pneumatic testing system consists of the following pneumatic and electro-pneumatic component sets manufactured by FESTO: TP 101, TP 102, TP 201, TP 220, TP 230, compressor and components for the measurement of servo-pneumatic system parameters, such as the proportional pressure valve FESTO VPPE-3-1/8-6-010, air vacuum/pressure sensors, displacement sensor, load cell and National Instrument USB-6211 data acquisition module.
