Requirements of diesel generator set ventilation

(1) The dampers or louvers play a role in isolating the engine room from the surrounding environment, and their opening and closing operations should be controlled by the operating status of the unit.

(2) cold areas of the engine room installed movable dampers, should allow the recirculation of airflow in the engine room, in order to heat the engine room when cold to improve the utility of the unit diesel generator rental.

Hazards of improperly treated generator cooling water:

Insufficient cooling water or cooling water, oil temperature is too high to run. Diesel generator cooling water is not enough to reduce its cooling effect, the diesel engine can not be effectively cooled and overheating cooling water, oil oil temperature is too high, will also cause the diesel engine overheating. At this time, diesel generator cylinder head, cylinder liner, piston components and valves and other major thermal load, its mechanical properties such as strength, toughness and other sharp decline, so that the parts deformation increased, reducing the fit clearance between the parts, accelerating the wear and tear of the parts, and in serious cases will produce cracks, parts stuck failure. Diesel generator overheating will also deteriorate the diesel engine combustion process, so that the injectors do not work properly, poor atomization, increased carbon. In addition, the case of insufficient oil running is also a practice that we may consistently take, so the damage to the equipment is also very large, increasing friction, causing the problem of pulling the cylinder or burning tile, so some of the wrong practices that have been taken for granted to correct in time, this is important diesel generator rental.

Diesel generator set ventilation requirements

What are the reasons for the poor cooling effect

(1) cooling water is not clean

Diesel generators with cooling water should be clean soft water, should not use hard water containing calcium, magnesium and other mineral salts. If the conditions are limited only hard water, must be used after softening treatment. Hard water softening can be boiled precipitation method; can also be used baking soda or caustic soda as a softening agent (according to 1L of water plus 0.5 a 1.5g soda or 0.5 a 0.8g caustic soda added to the ratio), stirring precipitation with the upper layer of clear water. Note that you can not use seawater as cooling water diesel generator rental.

　　(2) insufficient cooling water

　　Radiator cooling water should be frequently checked and timely replenishment, the liquid level is too low will affect the cooling effect of the system, intensifying the cavitation of diesel engine. If added every day, the cooling system should be checked for water leakage.

　　(3) V-belt elasticity is not appropriate

　　When the diesel engine is working, the v-belt should maintain a certain degree of tension. The belt is too tight will cause the charging generator, fan and water pump on the bearing wear intensified; too loose will make the driven accessories can not reach the required speed, resulting in charging generator voltage drop, fan air volume and water pump flow reduced, thus causing the diesel engine overheating, so the belt tension should be regularly checked and adjusted. The size of the belt tension is adjusted by adjusting the screws to adjust the relative position of the generator to the adjustment arm to achieve the diesel generator rental.
