The PT fuel system is a patented product of Cummins Engine Company of the United State. Compared with the fuel system of a typical diesel engine, the PT fuel system has its own unique features in composition, structure and working principle.
The DC motor is the motive force of the output torque, and most of its structures use a four-pole series-excited motor. Such a motor has a large output torque at a low speed and a strong overload capability.
Preparation before commissioning. The fuel pump and fuel injector have been tested by the test bench. The diesel engine technology is in good condition and has entered the hot running state; the fuel pump and the drive unit are properly connected, the gear pump is injected with clean fuel
The cooling system of the diesel generator set is forced liquid cooling, or pressure liquid cooling, that is, the diesel generator set has a dedicated cooling water pump to complete the circulating flow of the diesel generator coolant. According to the conditions of use of the diesel generator set, open cycle cooling or closed cycle cooling may be employed. Let's share the working principle of the open-circuit cooling system of the diesel generator set.
