Rust refers to the oxide produced when the metal surface comes into contact with oxygen, water, and acidic substances in the air, such as Fe0, Fe3O4, FeO3, etc. It is generally referred to as rust. The rust removal methods for diesel generator sets mainly include mechanical method, chemical acid was

The purpose of diesel generators:A diesel generator is a type of power generation equipment, whose main principle is that the engine of the diesel generator burns diesel, converts thermal energy into mechanical kinetic energy, and then drives the generator to cut the magnetic field to generate elect

Diesel generators may sometimes experience abnormal phenomena such as failure to start, inability to start, and abnormal smoke and odor. What is the reason for this? Are there any good inspection methods? The following will be revealed one by one:1. Normal starting speed, good cylinder compression,

Diesel generator set is currently the most reliable power equipment, which can quickly start when you need it, provide stable and reliable power supply in a safe and timely manner. Generally speaking, the expected service life of diesel generator set is between 20-40 years, but in reality, the servi

When a diesel generator catches fire, it produces a sharp, protruding, and uninterrupted metallic sound; Idle or low load is very prominent, accompanied by mechanical vibration; When the load is high and the speed is high, the sound decreases significantly and the operation tends to be stable. There

Whether working in the workplace or outdoors, you should read and understand these simple rules to ensure stable and reliable power supply in places that require electricity.1. Read the instruction manualAll operators should read the user manual and safety documents provided by the random group befo
