Chapter 1 PUMPING INSTALLATION
The model is generally constructed to a geometric scale of 1:10. Procedures for the tests should be
established prior to the test.
1.18 OPERATION & MAINTENANCE OF THE PUMPING INSTALLATION
In general, pumping units are either diesel-driven or electrical-driven and different qualifications are
required for the operation of ach type. In accordance with the Machinery (Person-in-Charge)
Regulations 1957 L.N.150 Regulation 6 (ii) the person in charge of the fixed pumping units must hold
Grade I or II Oil Engine Driver’s certificates as follows: -
Engine less than 40 hp --------- No certified driver required.
Engine 40 – 100 hp ------------- 2 nd Grade Driver for each shift.
Engine 100 – 500 hp ------------ 1 st Grade Driver for each shift.
Hitherto, electrically driven pumping units have been installed to most of the pumping stations.
Electrically powered stations must be operated in accordance with the AKTA BEKALAN ELEKTRIK
1990 and PERATURAN-PERATURAN ELEKTRIK 1994 (Clauses 60, 62 & 63)
In general a certified operator is not required to stop and start electrical motors but he is required if
he has any other electrical duties e.g. maintenance of electrical gear. In such cases the electrician
will be required to hold an Electrical Chargeman’s certificate (medium pressure) issued by
Suruhanjaya Tenaga.
Permission of the Suruhanjaya Tenaga must be obtained in writing before any station can be placed
in the charge of an unqualified operator.
If electrically unqualified operators are employed to stop and start motors only, they should be
required to sign a statement that they have read and understood standing orders and will obey
them.
The standing orders must be explicit and state procedure to be followed if any fault in the electrical
system develops. Under no circumstances must an unqualified operator attempt to trace or rectify
the fault.
In addition to technical qualifications detailed above and required under the Electricity Ordinance,
operators shall also have the following qualifications:-
- Able to write clearly and neatly in Romanised Bahasa or English;
- Have a knowledge of first aid as applied to treatment of electrical shock;
- Be intelligent and trustworthy, and
- Have fitter or mechanical equipment maintenance experience.
Pumping stations should be regularly visited and inspected by the Mechanical Engineer, particularly
before pumping period is expected to end so that the necessary major repair work could be arranged
before hand. As double cropping becomes more popular it will be increasingly necessary to ensure
all equipments are in good running order before the next season commences.
The civil engineering staff inspections of the pumping station should be regular during the pumping
season and should include the following: -
- Inspect the master log and the daily log. The master log should be in permanent book from
and in addition to recording all running times, water level figures etc. should include all work
done on the unit by fitters and workshops staff, spares fitted, and any other incident connected
with the unit. It is a complete diary of the station;
