MT 140.01 Assembly exercise piston compressor: functional test



  • Test device for the piston compressor assembly exercise from the parts sets MT 140.02 or MT 140
  • Permits assessment of the assembly


Technical Description

The MT 140.01 test device is used in conjunction with the piston compressor assembly exercises, MT 140.02 or MT 140. The fully assembled compressor is placed on the test device. Here the complete system is professionally assembled, including alignment of the motor and compressor. The electrical connection of the compressor can also be demostrated if required as part of the teaching process. A successfully completed assembly exercise can then be examined for operability using a formal test procedure. During the functionality test, the pressure rise in the tank and the current consumption of the drive motor are recorded over time.

The components of MT 140.01 are clearly laid out on a base plate. The unit contains an electric motor with belt pulley and protective screen. A switch box is included with displays and controls as well as a pressure vessel with display, safety valve and pressure switch. An ammeter on the switch box indicates the current consumption of the drive motor. The compressor being checked is installed on the test bed and connected to the drive motor via a belt drive.

Learning Objectives / Experiments

in conjunction with a piston compressor (MT 140 or MT 140.02)
- functional testing of a piston compressor
- pressure rise in tank over time
- current consumption of drive motor as function of pressure
- familiarisation with a compressed air generator and its components
- function and mode of operation of safety elements 
  * safety valve
  * pressure switch
  * non-return valve
- professional installation of the compressor in the test device, including setting and alignment
