A DIESEL GENERATOR SET IS A TYPE OF POWER EQUIPMENT THAT IS DRIVEN BY A DIESEL ENGINE. GENERATORS ARE WIDELY USED DUE TO THEIR FAST START-UP, EASY OPERATION AND MAINTENANCE, LOW INVESTMENT, AND STRONG ENVIRONMENTAL ADAPTABILITY. DUE TO THE MARKET DEMAND FOR LARGE GENERATOR SETS, THE NUMBER OF MANUFACTURERS HAS GROWN RAPIDLY, RESULTING IN A LARGE NUMBER OF UNITS IN THE MARKET WITH VARYING QUALITY. THEREFORE, CUSTOMERS NEED TO PAY ATTENTION TO SOME DETAILS WHEN PURCHASING DIESEL GENERATOR SETS, WHICH CAN DETERMINE THE QUALITY OF THE PRODUCT.GENERALLY, DIESEL GENERATOR SETS ARE DIVIDED INTO FOUR PARTS, NAMELY DIESEL ENGINE, GENERATOR, CONTROLLER, AND AUXILIARY PARTS. AMONG THEM, DUE TO THE UNIT OF OUTPUT POWER OF THE ENTIRE DIESEL ENGINE AND THE COST OF MOST PEOPLE'S DIESEL GENERATOR SETS, THIS PART IS USUALLY AFFORDABLE FOR SOME MANUFACTURERS. POINTS TO NOTE WHEN PURCHASING A DIESEL GENERATOR:FIRSTLY, THE OLD RENOVATIONMOST BRANDS REFURBISH OLD MACHINES, AND IT'S DIFFICULT FOR PROFESSIONALS TO DISTINGUISH BETWEEN THEM. THE REFURBISHED MACHINE, HOWEVER, ALSO HAS SOME DEFECTS, SUCH AS PAINT, ESPECIALLY DEAD PAINT, WHICH IS DIFFICULT TO ACHIEVE THE SAME AS THE ORIGINAL.SECONDLY, IMITATE FAMOUS BRANDS AND USE FAKE MACHINESDIESEL ENGINES ARE ALMOST ALL WELL-KNOWN UNIVERSAL MANUFACTURERS IN THE CURRENT MARKET, WITH SOME MANUFACTURERS USING COUNTERFEIT ENGINES OF THE SAME SHAPE, NAMEPLATES, PLAYING WITH REAL, FALSE INFORMATION, AND OTHER PRINTING FACTORY DECKS TO GREATLY REDUCE COSTS. DISTINGUISHING DECK MACHINERY FROM PROFESSIONALS IS DIFFICULT TO ACHIEVE.THIRDLY, THERE IS CONFUSION IN THE CONCEPT OF RELATED PRODUCTSSOME MANUFACTURERS EXAGGERATE THE POWER OF KVA KILOWATTS, CONFUSE THE RELATIONSHIP BETWEEN KVA AND KILOWATTS, AND THEN SELL THEM TO CUSTOMERS. IN FACT, KVA IS CONSIDERED AS POWER, AND KILOWATTS ARE EFFECTIVE POWER. IMPORTED UNITS USUALLY USE KVA TO INDICATE POWER UNITS, WHILE DOMESTIC ELECTRICAL EQUIPMENT GENERALLY USES KILOWATTS. THE RELATIONSHIP BETWEEN THEM IS 1 KVA=0.8 KILOWATTS.FOURTH: USE THE NAME OF THE FACTORYSOME MANUFACTURERS DARE NOT IMITATE FAMOUS BRANDS OF DECKS, MODIFICATIONS, FACTORIES, AND DIESEL ENGINES TO CONFUSE THE PUBLIC. FOR EXAMPLE, XX COMPANY, STANFORD CUMMINS GENERATOR, ETC., BUT THESE PRODUCTS HAVE NO ASSOCIATION WITH CUMMINS ENGINES OR STANFORD GENERATORS. THE COMPANY ONLY REGISTERS THE NAME XX GENERATOR, WITHOUT ANY RELATION TO THE "CUMMINS" TRADEMARK. MANUFACTURERS WILL PRODUCE VARIOUS BRANDED ENGINE CONFIGURATIONS AND PURCHASE ALL EXTERNAL CUMMINS GENERATOR SETS.TODAY, IN MOST DIESEL GENERATOR MARKETS, MANY MANUFACTURERS PRODUCE THEIR OWN PRODUCTS. CUSTOMERS MUST KEEP THEIR EYES OPEN AND PURCHASE CAREFULLY FOR THE QUALITY UNITS GENERATED BY A LARGE AMOUNT OF UNEVENNESS.
