Master these tips, diesel generator set cooling water tank easy maintenance

The water tank is an important part of the closed-cycle cooling system of Shangchai diesel generator set, as coolant cooling, according to the reduction of the calibration power and operating load rate of Shangchai diesel engine, can be equipped with the same form, different specifications of the cooling area of the water tank.
The water tank is an important part of the closed-cycle cooling system of Shangchai diesel generator set, as the coolant cooling, according to the reduction of the nominal power and operating load rate of Shangchai diesel engine, can be equipped with the same form, different specifications of the cooling area of the water tank.
Water tank requires frequent maintenance to ensure the heat exchange of coolant and air. Under normal circumstances, Shangchai diesel generator set every 500h or so, the exterior and interior of the water tank should be cleaned. For its internal scale and precipitation impurities cleanup, can be first radiator water discharge. Then with a certain pressure of water (such as tap water), through the radiator core, until the outflow of water clean.
Water tank after using a period of time, if there is a leak, available solder repair. Individual tubes are severely damaged and can not be repaired, allowed to block the tube, but the number of blocked tubes can not be more than three, otherwise it may lead to Shangchai diesel generator set of water temperature exceeds the allowable range.
The pressure cover set on the water tank filling port can make the pressure of the system increase to a certain range, that is, the boiling point of the coolant is increased. So that the system can work normally at a higher temperature and a certain altitude, and also improve the cavitation resistance of the diesel engine and water pump. The pressure cover is equipped with steam valve and air valve, when the positive or negative pressure in the water tank exceeds the regulations, the valve located in the pressure cover will automatically open so as to achieve the purpose of steam discharge or air intake.
Shangchai diesel generator set in the work, the pressure cover should be tightly closed. To avoid hindering the normal work of the cooling system. Must often check the coolant level in the water tank and timely replenishment. The liquid level is too low will affect the cooling effect of the system, intensifying the cavitation of the diesel engine, it is necessary to add coolant to the water tank, but should be carefully engaged in order to prevent steam injury.
Note: Do not open the water tank pressure cover in the heavy-duty operation of the diesel generator set. It is best to unscrew the pressure cover after parking until the water temperature is below 70°C. Do not neglect.
In the diesel generator set before starting, to the empty cooling system should not be too fast when filling the coolant, then should spin loose cylinder head at the end of the water temperature gauge feeler to exclude the air in the coolant flow channel, full stop two minutes to wait for the air in the system to escape and then add one more, so as to prevent the water surface of the phenomenon of false full and avoid overheating of the diesel engine.
Diesel engine working in low temperature environment, after parking should immediately open the water valve, release all the cooling water in the water tank to prevent freezing.
Water tank installation, between the two installation feet and the support surface of the public chassis, should be installed with the water tank to bring the rubber damping pad or special B-type vibration damper to reduce the vibration transmitted to the water tank by the diesel engine. Such as the use of rubber vibration damping pad, the fastening of the double nut should not be tightened too tight. To not loose, otherwise it will reduce or lose the role of vibration damping.
The large accumulation of carbon will affect the service life of diesel generator sets, how often to clean the carbon?
After several years of use, is your diesel generator set in good condition?
