Insufficient cooling water. Cooling water is the heat carrier in the cooling circulation system, which means that the heat that needs to be removed from the engine body is carried away and dissipated by the water carrier. If the coolant in the cooling system is reduced due to leakage or evaporation, the heat naturally removed from the body will be reduced, causing excessive heat build-up in the engine, which corresponds to overheating of the engine. engine.
How to deal with water in mobile generator
It's probably not a voltage problem. Your deep well pump? Three-phase 380 V, this type of pump consumes very little energy and the current in normal operation should be 5 to 6 A.
I don't know if there was an ammeter when you bought it. have installed. Otherwise, have an electrician install one. When pumping water, checkcheck if the current on the ammeter is normal. too small, this means that the water table there is almost exhausted. Damage. I've met him before. It will be fine after a while, but it won't work after a while.
1. If water is found to have entered the generator, turn it off immediately if it is running. It is not allowed to start when stopped.
2. Support one side of the mobile generator set with a hard object and lift it so that the oil drain part of the engine oil pan is in the lowest position, unscrew the oil drain plug, remove it. oil dipstick and make the oil pan. The water inside drains out on its own. When the oil is about to drain, let the oil and water drain for a while, then tighten the oil drain plug.
3. Remove the air filter, replace the new filter element and soak it in oil.
4. Remove the intake and exhaust pipes and muffler, and remove any water from the pipes. Turn on the pressure relief, crank the diesel engine to generate electricity, and observe if water flows from the inlet and exhaust ports. If there is water drained, continue to rotate the crankshaft until all the water in the cylinder is drained. Install the intake and exhaust pipes and mufflers, add a little engine oil to the air inlet, crank the crankshaft a few times, then install the air filter.
5. Remove the fuel tank, drain all oil and water from it, check for water in the fuel system and drain it.
6. Release the waste water into the water tank and water channels, clean the water channels and add clean river water or boiled well water until the water float mounted. Turn on the throttle switch andstart the diesel engine. After starting the diesel engine, pay attention to the engine oil indicator rising and listen for any abnormal noise coming from the diesel engine. After checking whether all parts are normal, run the diesel engine. The operating sequence is first at idle, then medium speed, then high speed. The running time is 5 minutes each. After break-in, stop the engine and drain the engine oil. Add new engine oil again, start the diesel engine and run it at medium speed for 5 minutes, then it can be used normally.
7. Disassemble the generator, check the stator and rotor inside the generator, then dry them before assembly.
Users of mobile generator sets should pay attention to protecting the unit after the unit is wet and in humid environments, to ensure the normal operation ofu generator.
