  Diesel generators have been hot in the current market, more and more enterprises and factories will purchase diesel generators, but with the hot sale of diesel generators, recently there are many cases of used diesel generators as brand new generator sets for sale in the market. How do we determine whether the purchased generator set is used or new? Today Bambi generator manufacturers to tell you how to determine whether the equipment is used.

A question, ask the diesel generator production date, brand, model and some other professional issues.
Second look, see if the body has been repainted, the body of the label is consistent with the model on the instructions for use, check whether there are unburned particles inside the diesel generator, whether there are traces left by the burning of fuel.
Three test engine, by cranking the crankshaft, trigger the flywheel, start the machine, etc., the diesel generator set to do a careful check. Test engine is a very important step, the specific inspection steps are as follows:
1. crank the crankshaft, so that the injector nozzle oil supply. If the injector nozzle emits a crisp sound, indicating that the injector nozzle and plunger vice performance; such as the wheel room emits "wow" and other abnormal sound, it means that the equipment may be used diesel generator.
2、Turn the flywheel up and down, such as a loud sound, the crankshaft main shaft stem and the clearance between the shaft tile, may be used equipment.
3, toggle the flywheel, so that the piston is close to the lower stop, and then shake the flywheel, such as "Ta Ta" sound, the rod shaft stem and tile between the wear and tear, may be old equipment.
4, so that the cylinder depressurization, shaking the crankshaft, when the removal of depressurization, such as the piston rebound force is small, the flywheel rotary slow, indicating that the cylinder, piston, piston ring wear, may be used diesel generator.
5. Start the diesel generator. If the start after the discharge of dark gas, unstable speed and noise, indicating that the generator set may be old equipment.
