Causes of Paraffin Wax Changing into Liquid in Diesel Generator Set

Jun. 01, 2023

Now it is not sensitive to the pressure of the cooling system of the diesel generator set of Shangchai, and its operation is reliable. The service life of the diesel generator set of Shangchai is long. Since the opening of the thermostatic valve of the diesel generator set of Shangchai is directly affected by the steam pressure formed by the volatile liquid in the cylinder, it is sensitive to the working pressure of the cooling system of the diesel generator set, with poor reliability, short service life of the diesel generator set, and complex manufacturing process.

The push rod of Shangchai diesel generator set is fixed in the center of the bracket and inserted into the center of the rubber sleeve. The cavity formed between the rubber sleeve of the diesel generator set and the thermostat housing is filled with paraffin. To prevent paraffin from flowing out of the diesel generator set, roll the upper end of the thermostat housing of the diesel generator set inward, and press the rubber sleeve of the diesel generator set on the shoulder of the housing through the upper cover and gasket.


When the water temperature of Shangchai diesel generator set is lower than 76 ℃, the spring compresses the main valve on the valve seat and the main valve is completely closed. At the same time, drive the secondary valve upwards from the secondary valve seat to open the secondary valve. At this time, the cooling water of diesel generator set circulates in a small way. When the water temperature of Shangchai diesel generator set rises, the paraffin gradually becomes liquid and the volume expands, forcing the rubber sleeve of the diesel generator set to shrink, and generating lift at the conical end of the push rod of the diesel generator set. The fixed push rod of the diesel generator set generates downward thrust on the rubber sleeve and thermostat housing.


When the water temperature of Shangchai diesel generator set reaches 76 ℃, the downward thrust of the push rod on the thermostat housing of the diesel generator set overcomes the spring tension to open the main valve of the diesel generator set. When the water temperature of Shangchai diesel generator set exceeds 86 ℃, the main valve is fully opened, the auxiliary valve is fully closed, and the cooling water circulates. To change the cooling air flow through the radiator core of the diesel generator set, a shutter or windshield can be installed in front of the radiator of the diesel generator set to partially or completely shield the radiator core. The shutter can be operated by the operator with a handle or automatically controlled by the thermostat of the diesel generator set of Shangchai.
