When using
Huaquan power diesel generator set, the daily maintenance of water radiator is also something we cannot ignore, because water radiator plays a cooling role on the unit. If the daily maintenance is not proper, it will also reduce the service life of the generator set. Below, Huaquan diesel generator set manufacturer will introduce some relevant precautions for the use of water radiator:
1. Cleaning of water radiator
Water radiator needs regular maintenance to ensure the heat exchange between coolant and air. Under normal circumstances, the appearance and interior of the water radiator should be cleaned every 500 hours of diesel engine operation. To clean the internal scale and precipitated impurities, you can first drain the water in the radiator, and then use clean water with a certain pressure (such as tap water) to pass into the radiator core until the water flowing out is clean.
2. Maintenance of water radiator
After the water radiator has been used for a period of time, if there is a leak, it can be repaired with solder. When individual pipes are severely damaged and cannot be repaired, it is allowed to block the pipes, but the number of blocked pipes cannot exceed three, otherwise the outlet water temperature of the diesel engine may exceed the allowable range.
3. Daily precautions
The pressure cap installed on the water inlet of the water radiator can increase the pressure of the system to a certain range, which not only increases the boiling point of the coolant, so that the system can work normally at a higher temperature and a certain altitude, but also improves the anti-cavitation ability of the diesel engine and water pump. There are steam valves and air valves in the pressure cap. When the positive pressure or negative pressure in the water radiator exceeds the specified value, the valve in the pressure cap will automatically open to achieve the purpose of steam discharge or air entry.
When the diesel generator is working, the pressure cap should be closed to avoid hindering the normal operation of the cooling system. It is necessary to check the coolant level in the water radiator frequently and replenish it in time. Too low a level will affect the cooling effect of the system and aggravate the cavitation of the diesel engine. At this time, it is necessary to add coolant to the water radiator, but be careful to prevent steam from hurting people.
[Huaquan Power Reminder]: Never open the water tank pressure cap when the diesel engine is running under heavy load. It is best to unscrew the pressure cap after parking until the water temperature is lower than 70o. Do not neglect it.
Before starting the diesel engine, the coolant should not be added to the empty cooling system too quickly. At this time, the water temperature gauge sensor at the outlet pipe end of the cylinder head should be loosened to remove the air in the coolant flow channel. After filling, stop for two minutes to wait for the air in the system to overflow and then add it again.
[Huaquan Power Reminder]: For diesel engines working in low temperature environments, the water valve should be opened immediately after parking to drain the cooling water in the radiator to prevent freezing and cracking.
