Common Failures and Handling Methods for the Thermostat of Yuchai Diesel Generator Sets

Thermostat is an indispensable component to ensure the Yuchai diesel generator set to operate normally. As an important part for cooling system of diesel generator, the thermostat can automatically adjust the amount of water flowing through the radiator according to the generator load and coolant temperature, ensuring the diesel generator operates within an appropriate temperature range.

Thermostat Structure: thermostat always installed at the outlet pipe connection of the cylinder head. It is a corrugated cylinder made of brass sheet, which is assembled into a stamped outer casing. There is easily vaporizable liquid or alcohol inside the cylinder. One end of the corrugated cylinder is equipped with two valves of different sizes.

No component can avoid failure or damage during operation. So, the thermostat is no exception. This article will introduce the handling methods and common failure of thermostat during using the Yuchai diesel generator set.

Common Failure of Thermostat

During operation of Yuchai diesel generator sets, the common failure of the thermostat is that the water outlet valve fails to open and close smoothly. If the water outlet valve opens too early, the warm-up time of the Yuchai diesel generator will be prolonged.

Maintenance Methods for a Damaged Thermostat

The thermostat is generally replaced with a new one when damaged. Cracks can also be repaired with solder in special cases.

Specific methods: repairs the damage place with solder, and repair the damaged area with solder, then inject alcohol or ethanol above the expansion bellows using a syringe. Then place the thermostat in hot water. After the alcohol or ethanol expands and expels the air, seal the pinhole with solder. To prevent volatilization of the alcohol or ethanol, the soldering must be done quickly. The thermostat is generally installed at the outlet pipe connection of the cylinder head.
