Correct Maintenance of The Three Filters in Diesel Generator Sets 1

The "three filters" of a diesel generator refer to the air filter, fuel filter, and oil filter. In the maintenance of a diesel generator set, the maintenance of the three filters is very important. The quality of their work directly affects the performance and service life of the diesel generator set. Currently, Dingbo Power has found that some users do not properly maintain the "three filters", resulting in frequent unit failures and premature entry into the maintenance period. It is worth noting that if the "three filters" of a diesel generator leak oil or crack due to manufacturing reasons, they can be repaired normally, but damage caused by improper maintenance is not covered by the warranty. Below, Dingbo Electric will introduce the correct maintenance techniques for the "three filters".

1、 Oil filter

Oil filters can be divided into three types: centrifugal oil filters, paper oil filters, and metal slotted filters.

1. Key maintenance points for centrifugal oil filter

Special attention should be paid to the installation of the centrifugal fine filter after disassembly and cleaning, and there should be no jamming phenomenon. The inspection method is: after reinstalling the rotary filter, rotate the rotor with force by hand, and let go. If the rotor can rotate 2 to 3 turns and then stop, it is qualified.

2. When the pressure difference between the oil before and after the paper oil filter exceeds 1 kg/cm2, it indicates that the filter has been blocked and the oil cannot be filtered, which will enter the oil passage and increase wear. Therefore, maintenance should be carried out every 50 hours of operation, and the filter should be replaced within 150-200 hours, otherwise the filtering effect will not be achieved.

3. Metal belt gap filter, this type of oil filter should be cleaned once every 50-60 working hours. During cleaning, it is necessary to ensure that the metal mesh belt is not damaged, and cotton yarn or other objects are not used to scrub, in order to prevent blockage and sealing of the mesh.
