RT552

This trainer provides a comprehensive experimental introduction to the fundamentals of control engineering using an example of continuous pH control. A caustic solution is added to fresh water by way of a metering pump. The pH value of this solution is measured. The acid is then added to the solution as a neutralising reagent by way of a second metering pump. The chemical reaction occurs in a pipeline system.

PT500
PT500

In order to avoid serious damage to machines and to carry out maintenance on time, the condition of the machine must be known. The state of a machine or machine parts can generally be judged well in terms of the type and size of its vibrations. The machinery diagnostic system can be used to simulate certain types of damage and investigate its effects on the vibration spectrum.The PT 500 base unit permits vibration measuring exercises (measurement of vibration displacement, velocity and acceleration in the time/frequency range). Field balancing of rigid rotors and alignment of shafts can also be practiced.

PT500.11

Cracks due to material fatigue are very dangerous for rotating machines. Early detection of any crack is therefore essential before permanent rupture and often fatal consequences can occur. The crack influences the vibration behaviour of the shaft by changing its rigidity. Using suitable analysis software, this change can be registered and inspection of the machine organised in good time.

Vibration analysis is a key tool in estimating the condition of a roller bearing. The slow change in the vibration spectrum provides indications of the remaining life of a bearing and can be used as a criterion for its replacement. The spectral distribution can deliver accurate information on the type and location of the damage.

Rotating machine elements are interconnected by way of couplings. A coupling exhibiting production or assembly faults generates machine vibrations which can be analysed to give an indication of specific faults or damage.The PT 500.13 accessory set can be used to simulate various faults and investigate their effects on vibration behaviour

IA520
IA520

The IA 520 training system presented here represents a fully functional CIM cell (CIM = Computer Integrated Manufacturing). The system allows an automated manufacturing process to be created. The IA 520 demonstrates the basic processes of handling (robots), manufacturing (CNC machining), and control (PLC). An overhead robot on a travel unit supplies two CNC machines with raw parts taken from a magazine. The machined dimensions of the parts are checked in an inspection station before the parts are placed in a finished parts store. Defined planning and control data is used to control various machines. The relevant data is stored in a software program, and is processed by the control units of the individual machines. A PLC system monitors and controls the process. The manufacturing cell is equipped with all necessary sensors and control devices.

RT396
RT396

RT 396 allows the characteristics of different valves and fittings to be compared. The typical kinds of valves and fittings are represented by a ball valve, a butterfly valve, a gate valves, a shut-off valve and a control valve. A safety valve and a dirt trap are also investigated. All valves and fittings are flanged, and can be installed in a pipe section with variable length. The pipe section is part of a closed water circuit. Pressure measurement points upstream and downstream of the valve and fitting under test are linked by a differential pressure manometer. This manometer is fitted with a pressure switch which activates a warning lamp if the pressure difference becomes excessive, such as when the filter is clogged. An electromagnetic flow rate sensor permits precise recording of the flow rates.

The HL 962 assembly stands are connected with piping elements from HL 962.32 to form a complex piping and pump system. The tank system HL 962.30 is required so that the system can operate as a closed process.The tank system consists of a large high-level tank with a mounting frame, a low-level tank and connections with shut-off devices to the PVC piping system HL 962.32.The high-level tank has a capacity of approximately 1,5m³ of water. A manometer close to the base of the tank measures the base pressure, thereby indicating the fill level. The high-level tank supplies the intake pipes of normally primed centrifugal pumps, and ensures an adequate inflow head. Its inlet and outlet distribution points are located at a height of about 2m.
