5.4. Commissioning
This chapter includes all important instructions for the
operating personnel for the safe commissioning and op-
eration of the machine. The following information must
absolutely be complied with and checked:
•
Type of installation
•
Operation mode
•
Minimal submersion in water / maximum submersion
depth
After a longer downtime, these points must also be
checked and detected defaults must be repaired! The
operation and maintenance manual must always be
kept with the machinery, or in a dedicated place where
it is accessible for the entire operating personnel.
The following points must be taken into account to avoid
personal and material damage when troubleshooting ma-
chinery failures:
The commissioning of the machinery must only
•
be carried out by qualified and trained personnel
in compliance with the safety regulations.
•
All personnel working on the machinery must have
received, read and understood the operating instruc-
tions.
•
Activate all safety equipment and emergency switch-
offs before commissioning.
•
Electro-technical and mechanical settings must only
be carried out by specialists.
•
This machinery is only suitable for use under the indi-
cated operating conditions.
5.5. Preparation work
The machinery was constructed and fitted according to
the latest technology, so that it works for a long time and
reliably under normal operating conditions. This requires,
however, that you comply with all requirements and in-
formation. Small oil leakages of the floating ring seals on
delivery are not problematic, but they must be removed
before lowering/immersion into the pump medium.
Please check the following points:
•
Cable run – no loops, slightly tightened
•
Check temperature of the medium and submersion
depth – see machinery data sheet
•
If a tube is used for pressure, this must be rinsed
with clear water prior to use so that no deposits lead
to obstructions.
•
The pump pit must be cleaned for wet installation
•
The pressure-sided and suction-sided pipework sys-
tem must be cleaned and all gate valves must be
opened.
•
The pump casing must be flooded, e.g. it must be
filled completely with the medium and it must not
contain any more air. The de-aeration can be carried
out by means of suitable venting devices in the sys-
tem or, if available, by air-vent screws on the pressure
socket.
•
Check accessories, pipework, suspension devices for
firm and correct fitting
•
Check available level controls/protection against dry
run
5.6. Electrical System
The respective local and VDE regulations must be com-
plied with when choosing and installing the electrical
leads as well as connecting the motor. The motor must
be protected with a circuit breaker. The motor must be
connected according to the wiring diagram. Note the di-
rection of rotation! In the event of the wrong direction of
rotation, the machine does not perform as indicated and it
can become damaged under unfavorable circumstances.
Electric shock hazard!
Improper dealing with current may jeopardize your
life! All pumps with free cable ends must be connect-
ed by a qualified electrician.
5.7. Direction of Rotation
No check is required for single phase motors, since these
always run in the correct direction of rotation. The direction
of rotation must be checked in three phase motors before
commissioning. When using HOMA switchgear with LED
for direction of rotation, this control indicator flashes in
the event of wrong direction of rotation. The check can be
carried out by observation of the start-jerk. To do so, place
the pump vertically onto the floor, slightly on the edge and
switch on for a short time.
