Reasons for Cylinders Water Overflow of Cummins Diesel Generator Sets

Dec. 17, 2021

Cummins diesel generator set cylinder overflow problem can be divided into two specific reasons: Cummins diesel generator set cylinder head gasket is washed out, or Cummins diesel generator set cylinder head nut tightening torque is insufficient. In this article, Starlight Power generation equipment will be introduced in detail.

1. The water pump of Cummins diesel generator set is faulty. We must first check whether the water pump works well. If it is found that the water pump drive gear shaft is worn out, it means that the water pump has no effect, and it needs to be replaced before the circulation is normal.


2. The coolant level of Cummins diesel generator set is too low or not in compliance with regulations. If the liquid level is too low, it can directly cause the coolant temperature to rise so that the coolant does not circulate. The coolant according to the rules is 50% antifreeze + 50% softened water + DCA4. If it does not comply with the rules, it will cause pipeline blockage and occur in the pipe wall. Rust, so that the coolant can not circulate normally.


3. Shortcomings of Cummins diesel generator thermostat. A thermostat is installed in the combustion chamber of the engine to control the temperature of the combustion chamber of the engine. The thermostat must be opened completely at the regulated temperature to facilitate small circulation. If there is no thermostat, the coolant cannot maintain the circulating temperature, and low temperature may occur. Call the police.


4. Air is mixed in the cooling system of the Cummins diesel generator set, and the pipeline is not dredged. Damage to the suction valve and exhaust valve on the expansion tank will also directly affect the circulation. At this time, you should always check whether their pressure values comply with the rules and inhale. The pressure is 10kpa and the exhaust pressure is 40kpa. In addition to this, whether the exhaust pipe is unblocked is also an important reason that affects the circulation.


5. The radiator fin of Cummins diesel generator set may be blocked or damaged. The radiating fan does not work or the radiating fins are blocked, so that the temperature of the cooling liquid cannot be lowered, and the radiating fins are rusty, which constitutes a liquid leakage phenomenon and can also constitute a poor circulation.
