Machinery diagnostic system, base unit (PT 500)

Machinery diagnostic system, base unit (PT 500)

base unit for setting up wide ranging experiments in machinery diagnostics using modular accessory sets

CodePT500

Description:

  • 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 500base 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.
  • The key components of the base unit are the mechanical elements (clutch, bearing blocks and shaft with rotors), the drive motor with variable speed via frequency converter and tachogenerator, and the display and control unit with digital displays for power output and speed.
  • The motor base plate is mounted on a carriage, enabling the motor to be aligned.
  • The large aluminium base plate with locating slots allows quick, flexible and precise assembly of the system components.
  • A transparent protective cover provides the necessary safety during operation, and enables clear system viewing during experiments.
  • All parts are clearly laid out and well protected in a storage system.
  • To measure and evaluate all experiments, the computerised vibration analyser PT 500.04is required.
  • The accessory sets PT 500.10– PT 500.19 enable repeatable simulation of the different types of damage.
  • Use of the trolley PT 500.01is recommended for flexible deployment of the training system.
