3,044,195 generator speed control board governor since the output voltage of the generator U = Cnφ, for a generator for, c is a constant. In operation 4913988, the rotational speed n is changing the original 4,913,988, to make the generator terminal voltage is kept constant, by varying the magnetic flux φ can be adjusted in size, while the size of the magnetic flux change is determined by the excitation current. Thus, when the generator rotational speed n increases, the right to use the field current can be reduced to reduce the magnetic flux to maintain the output voltage of the generator constant; Conversely, when the generator speed is reduced 4913988 supply, increasing the field current, silicon rectifier Thus the generator governor action of the voltage regulator is in the generator speed changes, automatically change the size of the excitation current. 1, before starting to prepare check, check whether the complete range of diesel engine parts; oil, water, gas line is firmly connected to the right; the output coupling is solid; if there is debris in the vicinity of the flywheel; 2, the new machine should be turned on after the fuel system exclude fuel filter and air injection pump; high-pressure pipeline should be leveraging the newly installed fuel pump timing screw, high pressure tubing filled with diesel fuel; 3, check the oil level position of the lubrication system. Including whether it is on the oil pan, and level position between the fuel pump and governor next two engraved lines; 4,913,988 supply, 4,913,988 faithful electromechanical provided by Dongguan Nan Zhongxin Electrical and Mechanical Services Department. Dongguan City, South City Zhongxin Electrical and Mechanical Services Department (zhongxin888.net.cn) strong, credible, in Dongguan, Guangdong and other industrial products industry has accumulated a large number of loyal customers.
