ST-IRZ-SAPSU testing machine


Automation of the process of testing the drives, pumping units for compliance with technical requirements after their overhaul, as well as during the incoming control of the consumer.

System components

  • operator workstation
  • control cabinet
  • ARM-ST-01 application software
  • set of connecting cables and adapters

Main advantages

  • acceptance testing of drives for ESP, sucker-rod pumps, progressive cavity pumps and linear pumping units with rated current up to 1000 A able to regulate the load in a wide range
  • testing for specific triggering of protective algorithms of the drive
  • calibration by input signals of drive
  • possibility of manufacturing a modification with a reduced power consumption (up to 30% of the rated value of the tested control system during testing)
  • possibility of manufacturing the installation according to the technical requirements of the customer
  • automation of the drive testing process with recording the test protocol in the database
  • reducing the time for testing the drive
  • diminishing influence of the "human factor" during testing
  • reducing the number of personnel for testing
  • saving protocols in the database during the full life cycle of the drive
  • significant reduction in energy consumption
  • building graphs of loads, voltages, currents, moments and others in real time

ARM-ST-01 software provides the following:

  • reading and storing of measurement results
  • generation of required signals
  • check the ESP drive in manual and automatic mode
  • recording test results
  • storing history in a database
