Online testing: Test about Separators, ALCAP Fuel Oil System (CBT)

Make system malfunction.

Will not affect the system.

Water pressure loss can be accommodated for some time.

To provide different paths for the oil to travel.

To increase the complexity of the system.

To recirculate oil away from the separator in the event of an abnormal situation.

Midway between delivery height pressure and pressure required to overflow bowl.

Midway between feed pressure and pressure required to overflow bowl.

Not governed by delivery pressure or by overflow pressure.

It ensures better separation.

It reduces the speed of separation.

It is necessary to run the preheater.

ALCAP paring discs are larger to cope with more viscous oils.

ALCAP oil paring discs have regulating holes.

The edge of the ALCAP oil paring disc has 2 lips to make a seal and prevent air getting drawn in.

There is no difference, they are inter-changeable.

To prevent build-up of pressure when the drain valve is closed.

To allow movement to minimise over-heating.

So there is always a flow through the small hole in the flow control disc to stop it getting blocked.

To allow air to be vented from the oil paring chamber.

Parameter 20 relates to a separator type and should not be changed.

When commissioning a new installation or fitting a new EPC card.

When using a fuel oil separator to clean lube oil.

Installation parameters.

Service parameters.

Process parameters.

Timer parameters.

All of them.

The ALCAP Separator has to have a back-pressure of 1,5-2,0 bar to run on auto.

The back pressure regulating valve is automatic and part of the ALCAP principle.

The transducer monitors changes in the condition of the oil leaving the bowl.

The recirculation valve always changes position for an abnormal situation.

To adjust the EPC 400 to the correct variables for each installation to ensure optimal performance.

To adjust the EPC 400 for different separator types and installations, to ensure optimum performance.

It makes adjustments very easy.

Part of the fashion in moving to more sophisticated electronics.

Normally the ALCAP separator runs as a clarifier, and when draining water, it is a purifier with a restricted broken water seal.

By keeping interface outside the disc stack, the water seal is less important, only one flow control disc required.

With the ALCAP the chance of having the interface into the disc stack is reduced, because of the small hole in the flow control disc.

With the ALCAP we are not so concerned with the position of the interface, it can be outside the edge of the top disc. It is not necessary to change gravity discs to ensure correct interface position.

By keeping the sludge moist hard sludge is prevented, and a good discharge results.

To displace the oil and minimise on oil losses.

To check that the transducer is still working the reference has to change.

This puts a precise quantity of water into the oil, which can be measured by the transducer.
