Diesel generator set water leakage and generator oil pressure adjustment method

DATE:2019/6/24 14:43:14 HITS:546

A water leakage fault occurs, diesel generating set

Diesel generator, water pump, water tank cylinder head water outlet pipe, a water discharging switch in less than 3 months of use time appear the phenomenon of water leakage

Fault analysis:

This failure is due to the general operational staff to the diesel engine water radiator filler corrosive coolant or sea water caused by.

Fault reason:

( 1) the operator to the cooling water radiator are added in the cooling water is water, which caused the engine internal channel and outer interface damage. Therefore, the use of diesel engine must be in strict accordance with the provisions of the operation of diesel engine.

( 2) the operator within the water radiator antifreeze strong corrosive, causing water damage to components of diesel engine.

Troubleshooting method:

( 3) removing diesel engine damaged components, the water radiator and the body's internal waterways fresh-water flushing is completed, replacing the damaged part of a diesel engine.

( 4 ) the assembly, adjustment, trial found that diesel engine returned to normal, the fault is excluded.

In two, diesel generator oil pressure adjustment method

Diesel lubrication way to have two kinds: pressure and splash lubrication. Diesel engine in the process of operation, the engine oil pressure is too low or too high will affect the diesel engine lubricating quality. So, diesel engine at work must keep the oil pressure control in the specified range. 135 series of turbocharged diesel engine oil pressure general control in 0.25 ~ 0.35MPa ( 2.5 ~ 3.5kgf/cm2 ), turbocharged diesel engine oil pressure should be controlled at 0.35~ 0.45MPa ( 3.5 ~ 4.5kgf/cm2). No matter what type of diesel engine starting 1min, if observed in the oil pressure gauge pointer does not change, should be promptly down for inspection. Find out the cause and troubleshooting, and then starting the diesel engine and the observation of the oil pressure gauge pointer changes.

Diesel engine from the low speed to the rated rotation speed, oil pressure shall be increased gradually, the diesel engine reach the rated speed, oil pressure is slowly returning to the specified value. If the 20min within the oil pressure cannot be restored to a specified value, the oil pressure adjustment. Series 135 diesel engine in oil filter side is provided with a pressure regulating valve, remove the nut, loosen the lock nut, turn the adjusting screw with a screwdriver. Precession, oil pressure; rotated, oil pressure reducing. After adjustment, the nut can be, as shown in figure 12-21. Need to remind that, if after adjusting oil pressure or too low, the sucking disc and oil quality inspection.
