Kuis Sampling Minyak

Which hardware is best for sampling pressure channels above 500 psi?

• A long dead-leg of pipe with a plug at the end

• A pressure regulating valve or a coiled helix connected to a mini-mess valve

• A closed drain plug

• A mini-mess valve located at a bend

• A mini-mess valve located in a straight length of pipe

A vacuum sampler is needed:

• In low-pressure lines

• From non-pressurized wells

• From pressurized lines

• Answer a and b

• All of the above

Sampling of non-circulating splash/bath well should be done by:

• Removing the Drain Plug

• Using a flexible drop vacuum tube sample

• Using a flexible drop vacuum tube sample from the bottom of the well

• Obtaining a sample from the middle oil level of a rigid tube fixed inside the well

• This system should not be sampled

Sampling vacuum tube falling from the reservoir and tank should be done:

• From the bottom of the tank

• Where the oil return line drains back to the tank

• Where the suction line draws oil from the tank

• From the top layer of oil in the tank where water and dirt have settled

• From the middle of the tank

For typical hydraulic fluid, how full should the sample bottle be filled with hydraulic fluid?

• 50%

• 75%

• 90%

• 100%

• Doesn't matter

The sampling frequency of oil can be influenced by:

• Machine age

• Machine criticality

• Fluid (oil) age

• Operating conditions

• All of the above

The common sampling frequency for industrial oil is:

• Every two weeks

• Monthly (500 to 1,000 hours)

• Quarterly

• Every six months

• Yearly

After some initial changes, as the oil ages, the acid number generally:

• Trends down

• Trends up

• Remains very flat

• Oscillates up and down

• None of the above

After some initial changes that may occur, as oil ages, the baseline figure of the oil generally:

• Trends down

• Trends up

• Remains very flat

• Oscillates up as the oil ages and down when makeup oil is added

• None of the above

After some initial changes, as oil ages, the viscosity of aging oil generally:

• Trends down

• Trends up

• Remains very flat

• Oscillates up and down

• None of the above
