Tractor PTO test, PTO dynamometer, power takeoff




Tractor PTO test (power takeoff test) refers to a series of tests performing on a dynamometer which is connect to a tractor power output shaft and the tractor is stationary. Agricultural tractor PTO output power test parameters include speed, torque, power, fuel consumption and so on. Tractor PTO test, PTO dynamometer can be applied to tractor as PTO test. Once the gearbox and torque sensor are removed, it can be the internal combustion engine bench test.

Tractor PTO test, PTO dynamometer measurement parameters

 

  • PTO torque
  • PTO speed
  • Engine speed
  • Fuel consumption
  • Ambient temperature
  • Ambient atmospheric pressure
  • Ambient humidity
  • Oil temperature
  • Air intake pressure
  • Engine exhaust pressure
  • Cooling medium inlet and outlet temperature
  • Fuel pressure
  • Engine exhaust temperature

 

The above parameters are measured by the corresponding sensor and FC2022 Data acquisition module to complete. The sensor accuracy is not less than 0.5%. Taking into account the measurement and control system is scalable, the following signals or data should be measured:

 

  • Smoke signals or data from the opacimeter;
  • Air intake and exhaust flow measurement signals or data;
  • Emissions analyzer data (CO, NOx, HC, PM, CO2) signals or data.

Tractor PTO test, PTO dynamometer system composition

  • FC2012 AC Dynamometer controller
    For accurate measurement and control of motor speed and torque

 

  • FC2210 Fuel consumption meter
    For fuel consumption measurement of PTO test under different work conditions

 

  • FC2310 series Throttle actuator
    Automatic or manual control of the tractor throttle

 

  • FC2022 Data acquisition module
    For test data collection, processing and transmission

 

The PTO control system, using AC dynamometer, applies decentralized control, centralized management mode. It can be the automatic or manual operation. The diagram is as below.
