Fault analysis of Cummins diesel generator set

Cummins diesel generator set in a long time after the operation often appear aging unit parts, fit gap is too large and other phenomena, these faults should cause users to pay attention to.

Cummins diesel generator set fault one: low oil pressure

In the operation of Cummins diesel generator set, low oil pressure will cause poor lubrication of the transmission parts of the unit. If the oil road is blocked, there will be cylinder pulling, cylinder holding, bearing clearance is too large, which directly affects the normal use of Cummins diesel generator set.

Low oil pressure of Cummins diesel generator set is mainly related to the following aspects:

(1) Cooling system: oil cooler blocked; The external void of the heat sink is blocked.

(2) Lubrication system: oil filter dirty; Oil suction pipe blocked; Oil pressure regulator failure.

(3) Mechanical adjustment and repair; Improper bearing clearance; The engine needs an overhaul; Main bearing or connecting rod bearing damaged.

(4) Use and maintenance: engine overload; Oil should be replaced on time, to ensure the correct use of oil filter element. Only in accordance with the correct maintenance method can ensure the normal use of the unit.

Cummins diesel generator set failure two: coolant does not circulate

In cummins diesel generating sets are often encountered coolant without circulation, including large cycle, no small cycle, or with minor cycle without systemic circulation, prompted a cylinder unit temperature rising fast, high oil temperature rise caused by the sudden stop wait for a phenomenon, directly affects the safe usage of cummins diesel generator set.
