Today, the diesel generator set manufacturer will take everyone to understand the process of preheating to starting up a diesel generator set.

I. Preheating:

The unit with a preheater, before starting, can decide whether to preheat the diesel generator set according to the ambient temperature. The preheating button on the control screen can control the engine to start heating to achieve the preheating purpose.

II. Power-on:

Turn the control screen key switch from OFF to ON, observe the background lights on the instrument panel to turn on, indicating that the control screen is powered on, and the diesel generator set fuel system is in an open state. The electronic governor or electric injection controller of the unit is also in working condition.

Diesel generator sets are used in many places in life, such as hospitals, communications, banks, oil fields and other places related to people's livelihood. Whether it is to provide power or serve as a power reserve, generators are essential equipment. Wrong starting method will greatly shorten the life of the unit, so everyone should pay more attention to it.

1. Wrong start method 1: Increase the throttle to start Please do not press the gas pedal when the generator is starting. Just put the throttle to the idle position. Some operators want the diesel generator to start quickly and slam the accelerator before or during the start. This will cause a waste of fuel, reduce the lubrication effect and cause greater damage to the moving parts of the diesel generator.

2. Wrong start method 2: Engine oil and fuel are not replaced according to seasons

Analysis of overvoltage protection malfunction after generator set protection replacement.

With the rapid development of microcomputer relay protection, microcomputer protection has replaced rectifier protection and electromagnetic protection, and has increasingly shown the reliability and superiority of microcomputer relay protection, greatly improving the safe operation level of equipment and systems. However, during the process of technical transformation, on-site personnel often only pay attention to the transformation of the protection device itself and ignore the secondary circuit, which brings hidden dangers to the normal operation of microcomputer protection. This article takes an actual accident in our factory that caused the generator overvoltage protection to malfunction and trip due to a voltage transformer secondary circuit problem as an example. We analyze the reasons and formulate measures for your reference.
