The incoming water must be dried and it cannot be dried without removing the cover. Even though it can be used temporarily, more serious problems may arise over time, so don't waste time and incur higher maintenance costs in the future.
There is a static sealing mechanism between the connection surface of the wiring port and the terminal, between the fixing bolt and the bolt hole, and a dynamic sealing mechanism between the shaft of the motor and the shaft hole.
The components on the outer surface of the engine are made of anti-corrosion materials or fixed with an anti-corrosion layer. Since the gaps or channels that may exist inside and outside the waterproof motor are blocked by the sealing mechanism, a reliable waterproof effect can be achieved even if exposed to water for a period of time. long time, water will not enter inside the engine. , causing afailure by short circuit. It also has certain explosion-proof properties.
Detailed information:
An electric motor is a rotating electrical machine that converts electrical energy into mechanical energy. It mainly includes an electromagnetic winding or a distributed stator winding to generate a magnetic field and an armature or a rotating rotor.Under the action of the rotating magnetic field of the stator winding, a current flows through the squirrel cage aluminum frame of the armature and is affected by the magnetic field to make it rotate. Some types of these machines can be used as electric motors or generators.

The spray box of the generator set belongs to the cooling system, and the following aspects should be considered when maintaining it ( if you want to find it, contact the generator maintenance company Maintenance, not a water treatment company): A. Water quality requirements must use clean water which meets the requirements of ASTM D4985. If this requirement is not met, cooling. The system may be blocked, causing a reduction in the cooling effect. If the water quality does not meet these requirementsences, distilled water or cooled liquid should be used. Total particles ＜340ppm silicon ＜20mgsio2perl total hardness ＜9.5dh iron ＜0.10ppm chloride ＜40ppm manganese ＜0.05ppm sulfuric acid ＜100ppm conductivity ＜500uspercmPH value 6.5～8 organic matter content CODmn <15mgk Mno4perlB. Coolant Replacement: The coolant used in the cooling system must be able to protect the engine interior from corrosion and icing (if the climate requires it). Never use water alone. The efficiency of the coolant will decrease after a while. Therefore, the coolant must be replaced. As long as you follow FDI Kang's coolant recommendations, you can adopt the following replacement cycle. Coolant Change Intervals Coolant (glycol mixture) and coolant filter every 4 years orat least every 10,000 hours Coolant (glycol mixture) without cooling filter Every year or at least every 5,000 hours Anti-corrosion agent Every year a. The cooling system must be flushed. When replacing the coolant, do not replace the coolant filter (accessory). The coolant filter should be replaced 6 months after the first coolant replacement, then every 6 months. b. If there is a risk of freezing, use a mixture of 50% antifreeze and 50% pure water. Mix the glycol and water in a separate container before adding the mixture to the system; there is never any risk of frost. Use a mixture of water and preservative as a coolant. The mixing ratio is 1:30. After adding the coolant, allow the engine to run at operating temperature, which can maximize the effectiveness of the additive.If the annual operating time exceeds 500 hours, 1/2 liter of anti-corrosion agent should be added to the coolant every 500 hours. However, regardless of climate, we recommend using a coolant mixture of ethylene glycol and purified water all year round. vs. Except in an emergency, do not open the water filler cap while the engine temperature is still very high. Otherwise, steam may escape. Check the coolant level daily before starting the engine and add more if necessary. The coolant level should be 5 cm lower than the sealing surface of the water filler cover. If a split expansion tank is installed, add between the MIN and MAX marks. Notice! When adding, use the same coolant as the original coolant in the cooling system. Notice! Don't mixNever use antifreeze (ethylene glycol) and corrosion inhibitors. Mixing these two substances will create foam and significantly reduce the effectiveness of the coolant. Notice! Refill the drained cooling system with coolant. Notice! Additives are harmful to the human body, please pay attention to safety when handling.
