PT414 Cummins PT Injector Test Bench Flow Calibration Stand

The PT414 Test Bench (technically based on the robust PT411 platform) is the final authority on injector performance. While the PT301 checks for leaks, the PT414 measures the actual fuel delivery quantity.

• Working Principle: It uses a cam-driven system (1000 rpm camshaft speed) to actuate the injector while pumping test oil through it. It simulates the engine's operation to measure how much fuel is sprayed over 1000 strokes.

• Digital Accuracy: The system counts strokes and measures volume digitally, displaying results with ±1ml accuracy.

• Temperature Control: Viscosity changes with heat. The PT414 includes a heater and cooler to automatically maintain test oil between 32°C and 38°C, ensuring consistent data regardless of workshop temperature.

• PLC System: An intelligent Programmable Logic Controller manages the test cycles, counting, and draining, reducing human error.
  

• Real-World Simulation: The 1.1KW motor and heavy-duty cam box replicate the mechanical actuation of the Cummins engine camshaft better than solenoid-based testers.

• Visual Flow Monitoring: Allows the operator to visually inspect the spray pattern and the oil flow quality through the sight glass.

• Safety & Stability: Features safety interlocks (cam box cover) and a robust steel tank structure (25L capacity) to dampen vibrations.

• Broad Range: Capable of testing small to large PT injectors with a measurement range of 90 to 500ml per 1000 strokes

FAQ:

• Q: Can this machine test Common Rail injectors?

• A: No, the PT414 is mechanically driven specifically for the Cummins PT "Push-Tube" system. Common Rail requires electronic actuation.

• Q: Does it come with different cams?

• A: Yes, the cam box is accessible, and cams can be changed to match the specific injector group (e.g., small cam vs. big cam engines).
