Solution of The Volvo Generator Set Coolant Circulation Failure

Today we will give you a brief introduction to the problem of solving the coolant circulation failure of the Volvo generator set. Now, we will introduce the relevant content for you.

The water pump of the Volvo generator set failed. First of all, we must first check whether the water pump works well. If it is found that the gear shaft of the water pump is worn over the limit, it means that the water pump has no effect and needs to be replaced before the circulation can be normal.

The coolant level of the Volvo generator set is too low or does not meet the requirements. 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 is 50% antifreeze + 50% softened water + DCA4 according to the regulations. If it does not meet the regulations, it will cause the pipeline to block and generate inside the tube wall. Rust, so that the coolant can not circulate normally.

The thermostat of the Volvo generator set is faulty. 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 fully opened at the specified temperature to facilitate small circulation. If there is no thermostat, the coolant cannot maintain the circulating temperature and a low temperature alarm may be generated.

Air is mixed in the cooling system of Volvo generator sets, causing the pipeline to be blocked. Damage to the suction valve and exhaust valve on the expansion tank also directly affects the circulation. At this time, you should always check whether their pressure values meet the regulations. The suction pressure is 10kpa, The exhaust pressure is 40kpa, in addition to the second, whether the exhaust pipe is unblocked is also an important reason for affecting the circulation. The radiator fins of the Volvo generator set are blocked or damaged. The cooling fan does not work or the cooling fins are blocked, so that the temperature of the cooling liquid cannot be lowered, and the cooling fins are rusted, causing liquid leakage and poor circulation.

Dingbo Power was founded in 2006 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, welcome send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
