Starlight generator

Engine is the power unit of diesel generator set, and the performance of the engine can directly affect the performance of the genset. There are many types of engines and the structure is different because of the need to adapt to different powers. There are two types of engine cylinder arrangement for diesel power generator: in-line and V-type. The cylinder is a cylindrical empty chamber in the engine in which there is a piston driven by the pressure of the working fluid or the expansion force. In-line Engine : In-line is a widely used cylinder arrangement. All of its cylinders are arranged side by side in a plane. Its cylinder and crankshaft are simple in structure and use a cylinder head. It has low manufacturing cost, high stability, low speed torque characteristics, low fuel consumption and compact size. The disadvantage is that the power is low. When the displacement and the number of cylinders increase, the length of the engine will increase greatly. At present, the number o

Today Starlight power company tells you how to judge fault by abnormal sound of Perkins diesel generator. Hope it is helpful to you. When   Perkins diesel generator   is operating, the noise is mainly from mechanical friction sound of diesel engine. Experienced technicians can judge the hidden trouble of a part of diesel engine from the sound. We can judge fault from following sound: 1.When Perkins diesel engine is running at low speed (idle speed), the metal knocking sound of "bar da, bar da" can be heard beside the valve cover. This sound is caused by the impact between the valve and the rocker arm. The main reason is that the valve clearance is too large. Valve clearance is one of the main technical indexes of diesel engine. If the valve clearance is too large or too small, the diesel engine will not work normally.   Too large   valve clearance causes the displacement between the rocker arm and the valve to be too large, and the impact force generated by the c

In order to ensure the safety of human body and power system operation, the diesel generator set is usually required to take grounding measures. According to different grounding purposes, it can be divided into working grounding, protective grounding and protective zero connection. The first way: working grounding. Due to the need of operation and safety of power system, the neutral point is often grounded, which is called working grounding. Working grounding has the following purposes: Reduce electric shock voltage.   In systems with ungrounded neutral point, when one phase is grounded, and other two phases touch the human body, electric shock voltage is 1.732 times of phase voltage. While in systems with grounded neutral point, electric shock voltage is reduced to equal or close to the phase voltage. Cut off faulty equipment quickly.   In systems with ungrounded neutral point, when one phase is grounded, the grounding current is very small( because there is electric ca

The fuel system of   diesel generator set   has direct injection type and electronic injection type. Starlight Power will introduce the difference between the two engines in this article. The engine has four strokes in normal operation: intake stroke, compression stroke, combustion stroke, and exhaust stroke. These four strokes work in a continuous cycle, thus generating a source power for the engine. The difference between the working principle of the EFI and the direct injection engine is the difference in the combustion stroke of the engine. The difference between engine direct injection and electronic injection: Direct injection   in the engine cylinder: The technology of direct injection of fuel into the cylinder and mixing with the intake air is to directly press the diesel into the cylinder of high temperature and high pressure, so that the diesel can spontaneously ignite and push the piston to move, thus achieving the working operation of the engine. Compared with the
