7.12 The raw water circuit
7.12.1 Clean raw water filter
Fig. 7.12.1-1: Raw water filter
The raw water filter should be released regularly from
arrears. In each case the water cock must be closed before.
It is mostly sufficient to beat the filter punnet.
If water should seep through the cover of the raw water filter,
this may be sealed in no case with adhesive or sealant.
Rather must be searched for the cause for the leakage. In the
simplest case the sealing ring between caps and filter
holders must be exchanged.
7.13 Causes with frequent impeller waste
The impeller of the cooling water pump must be regarded as wearing part. The life span of the impeller can be
extremely different and exclusively depends on the operating conditions. The cooling water pumps of the PANDA
generators are laid out in such a way that the number of revolutions of the pump lies low compared with other
gensets. This is for the life span of the pump a positive effect. Unfavourable affects the life span of the impeller, if the
cooling water sucking in way is relatively long or the supply is handicapped, so that the cooling water sucking in
range develops a negative pressure. This can reduce first of all the power of the cooling water pump extremely that
the wings of the impeller are exposed to very strong loads. This can shorten the life span extremely. Further the
operation of the impeller pump loaded in waters with a high portion of suspended matters. The use of the impeller
