Generator set drying method:
1. Baking method (oven)
If possible, disassemble the entire motor (it is better to disassemble the stator and rotor (Open)) and put it in the oven (oven) to heat and cook gradually. The oven (oven) must be ventilated. In order to remove moisture from the motor, it is best to sandwich it, with the inner layer discharging the motor and the outer layer heating. The temperature of the inner layer is maintained between 90-100°C and there should be no open flame, smoke, dust and other flammable and corrosive gases. It is generally necessary to cook continuously for 8-18 hours, during which the insulation resistance value of the motor can be measured several times until it reaches the specified value and is stable.
2. Steady state short circuit current method
Once the alternator is wet, short circuit the tthree phases into the output box, then increase the generator speed to the temporary speed. and keep it constant, then adjust the excitation current, first make the stator short circuit current reach 50%-70% of the rated current, keep it for 4-5 hours, then increase the excitation current to obtain the constant change. short circuit current reaches 80% to 100% of rated value to keep the coil temperature below 85°C, measure the insulation resistance and coil temperature every 30 minutes until until the insulation resistance reaches the specified value and stabilizes.
? Diesel generator water tank is an important component of water-cooled engine. As an important component of the heat dissipation circuit of water-cooled engine, it can absorb cylinder heat and prevent diesel. motor against overheating. Howevert, during use, users should pay attention that the water tank of the generator set cannot be without cooling water or add cooling water after starting.
If cooling water is added after the diesel generator set is started, important components such as hot cylinder liner and cylinder head will explode or deform due to sudden combustion and cold. Similarly, if boiling water at 100°C is suddenly added to a cold body, the cylinder head will crack and the body will break.
Yatong reminds everyone that the correct operation method of the diesel generator water tank is: before starting the diesel generator, cooling water should be added first and hot water of about 60℃ should be added to the diesel engine. preheat it before starting.
