Diesel testing unit - Q&A

Diesel testing unit - Q&A

HYDAC recently completed a diesel testing unit for HRL Technologies.  

The diesel testing unit is used to test diesel fuel injectors at a power plant.


Q1: What does the diesel testing unit do?

A: The diesel testing unit monitors supply, pressure, flow, and temperature of the diesel going into the furnace and then it monitors return pressure, flow, and temperature as well. 


Q2: What is the purpose of this monitoring?

A: The client wants to keep track of diesel going into the furnace and return thereof.


Q3: How many bar of pressure can the diesel testing unit achieve?

A: The diesel testing unit can achieve over 30 bar of pressure for a diesel system. 


Q4: Why is over 30 bar of pressure necessary?

A: Over 30 bar of pressure is necessary to get the diesel fuel to fully vaporise. Normal flushing and coalescing units are typically only rated for an operating pressure of 10 bar. 


Q5: What sensors come with the diesel testing unit?

A: The unit comes equipped with a full range of sensors connected to an HMG 4000. 


Q6: Give an example of a conversion the diesel testing unit can execute?

A: The diesel testing unit is programmed to convert flow rate (L/min) measured by the EVS flow turbines to mass flow rate (kg/s). 


Q7: What are the benefits of the diesel testing unit’s conversion from flow rate (L/min) to mass flow rate (kg/s)?

A: The conversion is helpful to the end user who generally calculates in kilograms.
