Engineering machinery is the most common due to high temperature failure, the water temperature is too high when you can not rush to open the water radiator cover heat, so easy to make hot water spray wounding, should be natural cooling and then replenishment; according to operational experience and engineering machinery operating specifications , The operator found the engine "boil", should immediately stop the operation, do not turn off the fire, so that the engine idling operation, while all open the blinds to increase the air flow, the water temperature in the cooling fan under the effect of slow down and release the cooling system A lot of bubbles. Wait for the engine to run idle for a few minutes, the water temperature has dropped and no longer boiling, with a towel or veil soaked in water radiator cover, carefully unscrew part of the water radiator cover, the release of water vapor, convinced that the water radiator water vapor release After the whole, and then all open the water radiator cover, in the process of unscrewing the water radiator cover, remember that the arm should not be exposed, the face to avoid the top of the nozzle, to prevent teaching equipment hot water spray scald face. If the engine has been turned off, to quickly start the engine and make it idle; if the engine can not be activated after the flame is turned off, you should turn off the throttle, shake the crank crank by hand; if no hand, you can intermittently use the starter Up and down the reciprocating several times, through the suction, exhaust ventilation, the teaching equipment will be out of the heat inside the cylinder.
When adding coolant, it is best to raise the same type of coolant in the water radiator, do not add tap water at will, unless it is done urgently. Laboratory equipment to the water radiator with cooling water, we must wait for the water temperature dropped to about 70 ℃ before; should take the "gradual water method" gradually cooling, and not a water too much urgency, that is, when the water The engine is idling, while slowly filling, steady flow, to ensure the safety of operators and equipment.
Brakes or other parts of the overheating, can not be used to cool the water, which will reduce its life and performance, resulting in deformation of the laboratory equipment parts or even crack, so it must be shut down to make it natural cooling.
