Why gasoline generators need regular maintenance
Why gasoline generators need regular maintenance
Ito Gasoline Generators are the suppliers of emergency backup power after mains failures. Most of the time, the units are in stand-by standby mode. Once a power outage occurs, the units are required to be “emergency start and power supply in emergency†or the standby units will be lost. Meaning, how can we achieve this goal? Practice has proved that strengthening daily maintenance is the most economical and effective method. Because the flight crew is in a static state, various materials of the unit itself will undergo complex chemical and physical changes with oil, cooling water, gasoline, air, etc., thus stopping the unit. Bad".
1, the unit start battery failure
The battery is unmaintained for a long time, and the electrolyte is not replenished in time after the water evaporates. The battery charger is not configured. The battery will be discharged after a long period of natural discharge, or the used charger needs to be periodically charged and floated. Due to the negligence of the switching operation, the battery power can not meet the requirements, in addition to the configuration of high quality chargers, the necessary inspection and maintenance are necessary to solve this problem.
2. Water enters the gasoline engine
As the water vapor in the air condenses during temperature changes, water droplets are attached to the inner wall of the tank and flow into the gasoline, causing the gasoline to exceed the water content. Such gasoline enters the engine's high-pressure pump and will rust the precision coupling parts. Plunger, serious damage to the unit, regular maintenance can be avoided effectively.
3, the maintenance period of oil (two years)
The engine oil is a mechanical lubrication, and the oil also has a certain retention period, long-term storage, the physical and chemical properties of the oil will change, causing the unit to deteriorate when the lubrication condition, and easy to cause damage to the unit parts, so the oil should be replaced regularly.
4. Replacement cycle of three filters (oil filter, machine filter, air filter, water filter)
The filter acts as a filter for gasoline, oil, or water to prevent impurities from entering the body. Oil and impurities in the gasoline are also unavoidable, so the filter plays an important role in the operation of the unit, but At the same time, these oils or impurities will be deposited on the filter wall, which will result in a decrease in the filter capacity, excessive deposition, and an unobstructed oil path. This will cause the oil machine to run with shocks due to the lack of oil supply. Oxygen), so in the normal use of the generator set, we recommend that: First, the common unit replaces the three filters every 500 hours; second, the replacement unit replaces the three filters every two years;
5, cooling system
Pumps, water tanks and water pipelines have not been cleaned for a long time, so that the water circulation 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, the consequences are: First, cooling If the effect is not good and the water temperature inside the unit is too high, the Weixin unit is the most common. Secondly, the water tank leaks and the water level in the tank drops. The unit will also fail to work properly. (To prevent the freezing of the water pipe when the generator is used in winter We recommend installing a water heater in the cooling system.
6, lubrication system, seals
Due to the chemical properties of the lubricating oil or oil ester and the iron scrap generated after mechanical wear, these not only reduce its lubricating effect, but also accelerate the damage of the parts. At the same time, due to the certain corrosion effect of the lubricating oil on the rubber seal ring, the other oil seal It is also aging at any time so that its sealing effect is reduced.
7, fuel, gas distribution system
The output of the engine power is mainly that the fuel burns in the cylinder to do work and the fuel is ejected through the nozzle. This causes the coke after combustion to deposit on the nozzle. With the increase of the deposition amount, the fuel injection amount of the nozzle will be affected. Impact, lead to inaccurate timing of injector ignition advance, engine cylinder fuel injection is uneven, the working status is not stable, so regular cleaning of the fuel system, replacement of the filter parts of its oil supply, matching The adjustment of the gas system makes it uniform.
8, the control unit of the unit
The control part of the oil machine is also an important part of the maintenance of the unit. The unit is used too long, the line connector is loose, and the AVR module is working properly.
