Why Should Diesel Generators Be Regularly Maintained And Maintained?

  Why should diesel generators be regularly maintained and maintained?

  Diesel generators are power failure after the power failure of the emergency backup power supply providers, the vast majority of time units in standby standby state, once the power failure, it requires the unit "emergency start, emergency power supply" or spare units will be meaningless, How can I achieve this? Practice has proved that: to strengthen the daily maintenance is the most cost-effective method, because the unit leader in the static, the unit itself with a variety of materials and oil, cooling water, diesel, air and other complex chemical and physical changes, so the unit "stop Bad".

  1, the unit starts the battery failure

  The battery for a long time no maintenance, diesel generator the electrolyte moisture can not be added in time to add, no configuration start battery charger, battery discharge after a long time to reduce the amount of electricity, or the use of the charger need to manually charge the full charge, In addition to the configuration of high-quality charger, the necessary inspection and maintenance is necessary, because the battery does not meet the requirements due to negligible switching operation.

  2, water into the diesel engine

  As the air in the water vapor changes in the temperature of the phenomenon of condensation, the formation of water droplets attached to the tank wall, into the diesel, resulting in excessive diesel water content, such diesel into the engine high-pressure pump, corrosion will be precision coupling ----- Plunger, serious damage to the unit, regular maintenance that is effective to avoid.

  3, the oil retention period (two years)

  The engine oil is mechanical lubrication, diesel generator and the oil also has a certain period of retention, a long time storage, the physical and chemical properties of oil will change, resulting in deterioration of the unit when the lubrication situation, easily lead to damage to the unit parts, so the oil to be replaced regularly.

  4, three filter replacement cycle (Chai filter, machine filter, air filter, water filter)

  Filter is played on the role of diesel, oil or water filter to prevent impurities into the body, and in the diesel oil, impurities are inevitable, so the unit in the process of running, the filter has played an important role, but At the same time these oil or impurities will be deposited on the filter wall leaving the filter filter capacity decline, deposition too much, the oil will not flow, so that the oil tanker will be running because of oil can not supply and shock Oxygen), so the normal generator in the use of the process, we recommend: First, the common unit every 500 hours to replace the three filters; Second, the replacement unit every two years to replace the three filters;

  5, cooling system

  Water pumps, water tanks and water pipes for a long time without cleaning, so that the water cycle is not smooth, the cooling effect is reduced, the water pipe joints are good, water tanks, waterways are leaking, etc. If the cooling system is faulty, diesel generator the consequences are: first, The second is that the water tank leaks and the water level in the tank drops, the unit will not work properly (in order to prevent the use of generators in the winter, the water pipe is frozen when the water temperature is too high , We recommend that water heaters be installed in the cooling system.

  6, lubrication system, seals

  Due to the chemical properties of lubricating oil or oil ester and mechanical wear generated after the iron scrap, which not only reduces its lubrication effect, but also accelerated the damage to parts, and because of the rubber on the rubber ring has a certain role in corrosion, Itself at any time and aging to seal the effect of decline.

  7, fuel, gas distribution system

  The output of the engine power is mainly fuel combustion in the cylinder and the fuel is injected through the nozzle, which makes the burning of carbon deposition in the nozzle, with the increase in the amount of fuel injection nozzle will be a certain Impact, resulting in fuel injector ignition advance time is not allowed, diesel generator the engine cylinder fuel injection volume is not uniform, the working state is not smooth, so regular cleaning of the fuel system, the replacement of the filter parts of its oil flow, The air system is adjusted so that it ignites evenly.

  8, the control part of the unit

  The control part of the oil machine is also an important part of the unit maintenance, the unit is used too long, the line connector is loose, AVR module work is normal.
