    • Answer: because the engine has the use of multiple pressure seal form, such as a cylinder / piston and piston ring, supercharger and turbocharger rotor shaft, the seal is generally about 1/3 load in the engine, to give full play to the role, and load hours may appear slight leakage. Therefore foreign engine manufacturers in their manual generally gave emphasis.

    • Answer: 1 ) The water in the water tank must be adequate, and keep the temperature range. 2) Lubricating oil must be in place, but not excessive, and keep the pressure within the scope of the work. 3) Frequency and Voltage Stability must be Controlled in Standard and Normal Level. 4) Three-phase current are rated range.

    • Answer: ( 1) oil lubricating system; ( 2) the fuel system; ( 3) control and protection system;( 4) cooling system; ( 5) exhaust system; ( 6) starting system;

    • Answer: the generator is not used for a long time before leaving the factory, lead containing in the core of the remanence loss, excitation coil has not established due to the magnetic field, when the engine is running normally but no electricity, this kind of phenomenon is the new machine. Or without long-term unit more.

    • Answer: 1 ) depending on the power unit is the KVA, our country used for expression of the transformer and the capacity of the UPS.

    • Answer: 1 ) to verify the true useful power unit. Then determine the economic power, and standby power. Authorized unit real useful power method for diesel engine rated power: 12 multiplied by 0.9 to get a data ( kw ), if the generator rated power is less than or equal to the data, the generator rated power for the unit real useful power, if the generator rated power from the data, it must be used in the data as a unit true and useful power.

    • Answer: 22*7=154KW ( elevator for the direct starting with load type, instantaneous starting current is generally rated current of 7 times, in order to ensure that the elevator at a constant speed ). ( which should be at least 154KW generator )

    • Description of the problem: how to identify fake domestic diesel engine?

    • Solution:
      1 check the daily fuel tank capacity, fuel is added when required
      2 if with fuel system, according to the 9.4.3 segments examined
      3 once the cause identified, press the reset button quenching alarm

    • Change with appropriate Fuse,and reconnected all lines
