If the air filter is not clean, the resistance will increase, the air flow rate will decrease, and the aeration efficiency will decrease, resulting in insufficient engine power. Clean the diesel-air filter core or dust off the paper filter as required, and replace the filter if necessary.
Many diesel generator shaft parts, such as crankshaft, camshaft, drive shaft and so on. The common damage forms of shaft parts are bending, wear and fracture. Test of shaft parts of diesel generator set, examination of wear and fracture test.
The generator and accessories must be stored in the proper manner until they are installed, and protected against moisture, dirt, various chemical substances, living creatures liable to cause damage and all other kinds of extraneous influence.
Oil in use will be mixed with some impurity particles, such as particles produced by friction, debris left over by unclean parts, and early oxidized particles produced at high temperatures in individual places. These particles include iron pins, sand grains, Rubber particles, mixed in oil will cause friction side effects, damage and even burning tile, reduce service life and reliability. Diesel engine oil filter must be used, oil filter mainly with paper filter, filter paper to filter out the impurities in the oil. Some filters can be divided into coarse filter and fine filter, the particles of 0.040mm can be filtered off 100%, the particles of 0.030-0.040mm can be filtered off 99%, if the concentration of particles below 0.030mm is too large, it will cause oil deterioration
