Use Of Oil Check Indicator - Beko CLEARPOINT M010X Installation Und Betriebsanleitung

Use of oil check indicator

To assess the compressed air temperature, an adapter (1)
with an oil check indicator is mounted on the head of the filter/
absorber. When the needle valve (3) is opened fully, a specific
volumetric flow will pass through the detector tube (5). The oil
residues in the compressed air cause the detector tube to turn
red from the bottom upwards.
Important information :
1. The oil check unit is designed to allow measurement without
danger to operating personnel. However, prior to measure-
ment it must be checked that the detector tube connection
(4) is firmly screwed on before opening the needle valve
(3).
2. The unit incorporates a pressure reducer (2) upstream of the
needle valve (3) to reduce the pressure at the detector tube
to a maximum of 7 bar. With higher operating pressures, 7
bar should therefore always be used as the standard value
for the determination of the oil content.
3. The usability period of the oil check indicator is limited by
the measurement duration (several days or continuous in
the case of low oil contamination) and the oil content of the
compressed air. When the detector tube has turned red from
bottom to top, it will need to be replaced:
- Close needle valve (3)
- undo threaded connection (4)
- install new detector tube (5)
4. When the oil check indicator is used in areas with moist
compressed air, a pink coloured section will appear above
the red coloured section. This pink section should not be
taken into account for the assessment of the oil load.
5. The oil check indicator must be mounted in a vertical po-
sition.

Checking of mean oil content dowstream of filter
/ activated carbon absorber
The data sheet (page 26, 27) included with the Instructions for
Installation and Operation can be used for documenting the
compressed-air quality check.
The duration of the oil check depends on the quality of the
compressed air. Where the oil content is expected to be below
0.01 mg/m³, the check duration should exceed 500 h, so that
continuous measurement would then be the most convenient
method.
The applicable check duration should be chosen by the op-
erator on the basis of experience and the speed of the colour
change to red.

Check procedure :
a) Start
Make sure that the detector tube connection is firmly screwed
on, otherwise there is a risk of injury because the detector tube
could shoot out when the needle valve is opened.
- Prepare the check log: name, date, starting time, operating
pressure, temperature, scale value of red coloured section
- Mark the current position of red colouring (existing oil load
inside detector tube)
- Fully open the needle valve upstream of the oil check indica-
tor for a specific period (see recommendation)
b) End
Mark the new position of red colouring on detector tube
- Enter details in check log: name, date, time of start, operating
pressure, temperature, scale value of red coloured section,
additionally value of scale section turned red during the oil
check, check duration (in hours), operating pressure
c) Calculate the oil load of the compressed air
- On the basis of the relevant quantitative colouring, check
duration and operating pressure, the oil load is determined
using the following chart:
