Many diesel filters become clogged and fail prematurely,not solely due to filter quality issues,but also closely related to diesel quality and daily maintenance habits.Proper maintenance not only protects the filter element,but also protects expensive high-pressure fuel pumps and injectors.

　　Firstly,maintain on time and do not use beyond the expiration date.Replace after 500 hours of standard operating conditions;The diesel sources for mines and construction sites are diverse,which can be shortened to 250-300 hours.After the filter element is clogged,some of the filter elements with bypass valves will bypass directly,and unfiltered diesel will enter the engine directly,which is equivalent to the complete failure of the filter element and brings huge hidden dangers.

　　Secondly,the oil-water separator should be drained regularly,and the bottom drain plug should be opened every week for drainage;After adding low-quality diesel in rainy and humid environments,it is necessary to drain the water.After the water cup is filled with water,the moisture directly passes through the filter element and enters the fuel system,corroding the fuel pump nozzle.

　　Thirdly,pay attention to protection when refueling,cover the dust cover of the refueling port,and do not let sand or dust fall into the fuel tank.Try to choose diesel with reliable quality.Rust,sediment,and accumulated water will settle at the bottom of the fuel tank,and conditions allow for regular cleaning of the diesel tank.Impurities at the bottom of the fuel tank can repeatedly contaminate the new filter element.

　　Fourth,regularly check the low-pressure oil circuit.Aging oil pipes and loose clamps can suck in air,resulting in difficulty starting and unstable power;Replace the damaged oil pipe in a timely manner.

　　After replacing the filter element,it is necessary to exhaust the air in the oil circuit.If there are bubbles in the oil circuit for a long time,it will cause cavitation and damage the high-pressure pump.In low temperature environments during winter,choose the corresponding grade of diesel to prevent wax buildup,which can quickly clog the filter element.

　　Once a large amount of rust and gum impurities are found inside the filter element,replacing the filter element only treats the symptoms and not the root cause.It is necessary to clean the fuel tank pipeline.The diesel filter element is a preventive maintenance component that requires early maintenance,which is much cheaper than repairing the high-pressure pump of the fuel injector in the later stage,reducing construction site downtime losses.
