The Importance of Cooling Water to Diesel Generator Sets

Most diesel generator sets are closed water cooled diesel generators. This kind of generator set is heat discharged by continuous circulation of coolant in the generator. When the diesel engine is used in environmental conditions below 0℃, the relevant parts of frozen diesel generator set should be careful to prevent cooling water from freezing.  Cooling water is generally replaced for two years, it must be replaced regularly.  When the diesel engine is finished, the cooling water should be put out, and the old liquid should be put out when the replacement. After the cooling system is cleaned, the new liquid should be replaced.  

The importance of cooling water to diesel generator sets, cooling water 2 provisions

It is very important to strengthen routine maintenance and observation of diesel generator.  When completing the high-temperature maintenance of cooling water, the troubleshooting operation process should be from easy to difficult and from easy to difficult. It should first consider whether cooling water is added according to the specifications;  The second consideration is whether the system has water leakage, scale, heat pipe radiator is not blocked;  Then to observe the belt is not loose, dry crack, etc.;  After removing the above problems can be considered whether the pump, thermostat or fan clutch damage.  

Provision of cooling water for diesel generators.

Diesel generator cooling water circulation system is a vital part of the unit, in the process of operation, must pay attention to the operation of the cooling water circulation system and use, otherwise it will cause severe cooling water cavity scale, the circulation area of small, poor heat conductivity, diesel engine cold trap heat and a series of failure, can cause early abnormal damage and a series of diesel engine fault.  

1, refrigeration requirements: suitable for softening cooling water, PH value 6-8.5, hardness: 0.7-5.3 mg equivalent calcium, magnesium ion/l, chloride ion;  <150 mg/l, usually can be purified rainwater, tap water or river water, not allowed to directly use well water, spring water and other hard water containing high salt and high alkali, if the user is limited by conditions, must be softened after treatment.  

2.Hard water treatment software: cooking: distillation, chemical treatment.

The problem of insufficient cooling effect of diesel engine means that the cooling water consumption, the failure to continuously cool the diesel engine with cooling water may cause its continuous heat generation;  Too high a temperature in the diesel engine means that the medium is too hot.  In mechanical properties such as compressive strength, toughness and other standards, cylinder head, cylinder liner, piston components and valves to absorb heat load, so that the deformation plus, smaller clearance between the parts, accelerating the damage of parts, and even cracks, parts stuck. Oil deoxidation from overheated oil.  Diesel engine required smooth parts can not be effectively smooth, abnormal damage.  In addition, when the diesel engine temperature is too high, its combustion power is reduced, the nozzle can not work effectively, damage the nozzle.

The above is the importance of cooling water for diesel generator set introduced by Dingbo.  The durability of equipment depends on personal care and responsibility.  Serious failures can be avoided if you use the generator carefully, follow the instructions, and replace the consumables in a timely manner.  Guangxi Dingbo Electric Power co., Ltd. produces 30-3000KW high-power diesel generator set, ultra-quiet diesel generator, vehicle-mounted power station, with 1-year ultra-long quality guarantee.
