RECAP ON CONDITION MONITORING

ATTEMPT ALL QUESTIONS, YOU HAVE 30 SECONDS TO ANSWER EACH QUESTION

YOUR ANSWERS ARE RECORDED

Multiple Choice

Condition Monitoring is used to

• predict when a component will fail

• speed up reactive maintenance

• ensure only O.E.M components are used

• test out monitoring equipment

Multiple Select

Predictive maintenance allows maintenance

• to take place at any time

• to only take place during shutdown periods

• Engineers to estimate when maintenance should take place

• to be be time based

Multiple Choice

Condition Monitoring normally occurs

• during the night shift

• on "dead equipment"

• on "live" equipment

• whenever you want

Multiple Choice

A filter on an installed auxiliary pump has a predicted life of 1700 hours. After an investigation it was found that the filter changes could be extended by 15%. From this information calculate THE MAXIMUM running hours for the filter

• 1795

• 1955

• 1715

• 1525

Multiple Choice

Condition monitoring and fault finding tasks should only be carried out if you

• are over 21 years old

• are working on nights

• trained

• wearing PPE

• trained, confident and competent

Multiple Choice

A typical Hydraulic press contains multiple systems, e.g. Electrical, Fluid power, Mechanical, which could be considered as critical systems that require condition monitoring

• Mechanical systems

• All of the systems stated

• Electrical

• Fluid power

Multiple Choice

The maintenance records for a Hydraulic press highlight the number 3 crankshaft bearing as being a critical component that is subject high loads and continuous operation, which of the following could be classed as critical to the bearings performance.

• Correct lubrication

• trained operator

• slow down the machine

• stop the machine for 10mins. every hour

Multiple Choice

The Power press is reliant on its Hydraulic systems for correct operation, what is a common cause of failure in hydraulic systems

• the operator

• solid particulate contamination

• Ali/Copper Hydrate hoses

• Mineral oil

Multiple Choice

Pneumatic systems are frequently employed in manufacturing, to be efficient they must operate at the correct pressure, which of the following is true

• temperature increases, pressure decreases

• increased pressure = leaks

• flow = pressure

• directional control valves control the pressure

Multiple Choice

when carrying out condition monitoring, environmental factors can

• have no effect on the outcome

• make it uncomfortable to work in

• be controlled by opening doors and windows

• adversely affect the quality of measurements taken

Multiple Select

mechanical components can suffer from many types of wear, which of the following can lead to premature failure in a bearing

• Incorrect Lubrication

• Poor installation techniques

• excessive axial load

• environmental factors
