Правильні відповіді:
1

A screw pump is a good solution to the feed pump required for the separator, because:

Ваша відповідь правильна:

It does not separate the particles in the oil before reaching the separator.
2

Loss of Water Pressure to the Valve block will:

Ваша відповідь правильна:

Make system malfunction.
3

One of the main functions of the three-way recirculation valve is:

Ваша відповідь правильна:

To recirculate oil away from the separator in the event of an abnormal situation.
4

The back pressure setting is:

Ваша відповідь правильна:

Midway between delivery height pressure and pressure required to overflow bowl.
5

The oil entering the separator should be preheated and of lower viscosity, because:

Ваша відповідь правильна:

It ensures better separation.
6

The oil paring discs for conventional and ALCAP separators are different in the following ways:

Ваша відповідь правильна:

The edge of the ALCAP oil paring disc has 2 lips to make a seal and prevent air getting drawn in.
7

What is the purpose of these holes?

Ваша відповідь правильна:

To allow movement to minimise over-heating.
8

When might you adjust parameter 20?

Ваша відповідь правильна:

When commissioning a new installation or fitting a new EPC card.
9

Which group of parameters may have to be adjusted for a different oil type?

Ваша відповідь правильна:

Process parameters.
10

Which of the following is most accurate?

Ваша відповідь правильна:

The transducer monitors changes in the condition of the oil leaving the bowl.
11

Which of the following statements best describe the purpose of parameters?

Правильну відповідь:

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

Ваша відповідь:

Part of the fashion in moving to more sophisticated electronics.
12

Which statement best describes why a flow control disc can replace a set of gravity discs?

Правильну відповідь:

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.

Ваша відповідь:

By keeping interface outside the disc stack, the water seal is less important, only one flow control disc required.
13

Why is water added to the ALCAP fuel separator bowl after each discharge?

Ваша відповідь правильна:

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