Six elements of long engine life
Engine longevity has the following six keys, the following Beidou power for you to list one by one: First, grinding: that is, running-in. This is the basis for extending the service life of the engine, whether it is a new engine or an overhauled engine, it must be run in accordance with the rule...Read more -
When reactive power or excitation current is adjusted, the spark of carbon brush changes obviously
Electromagnetic identity: When reactive power or excitation current is adjusted, the spark of the carbon brush is changed. When the exciter is reversed, that is, 1.2 times the calculated capacity is less than the capacity of the emergency diesel generator set, and the contact resistance is too la...Read more -
Causes of generator magnetic loss
Synchronous generators in the operation of sudden full or partial loss of excitation is often due to the following reasons: (1) excitation circuit, excitation device and its power supply failure; (2) exciter failure; (3) Rotor loop failure; (4) false action of magnetic switch; (5) Misoperation. ...Read more -
The harm of magnetization of generator rotor and how to deal with it
The rotor winding of the generator is grounded at one point, which generally does not affect the normal operation of the generator. If another point of grounding occurs in the winding or excitation loop, forming a two-point grounding, the rotor winding, rotor core or reguard ring may be burned by...Read more -
Equipment introduction of exhaust gas turbocharging system
Diesel generator exhaust gas turbocharging system: this is our usual turbocharging device, the supercharger has no mechanical connection with the engine, in fact, it is an air compressor, which increases the intake volume by compressing air. It uses the inertia impulse of the exhaust gas discharg...Read more -
Low load diesel generator set exhaust pipe dripping oil
If the diesel generator set runs under a small load, the following failures will occur over the duration of the operation: 1. The piston – cylinder liner seal is not good, the oil is channeling, burning into the combustion chamber, and the exhaust takes blue smoke. 2. For the turboc...Read more -
Why do diesel engines always leak
Why is the diesel engine always leaking oil? The following is a fault analysis for you. Maintenance of diesel generator sets: 1. Check whether the oil model, oil quantity and oil quality meet the requirements. 2. Whether the combination surface of various parts of the diesel engine...Read more -
What routine checks need to be done before the operation of the diesel generator set
Before the operation of the diesel generator set, the following routine checks should be done: First, appearance inspection: Whether the external engine of the generator set is damaged and complete, whether the screws are tightened, and whether the generator output line and control line a...Read more -
Assembly requirements for fasteners of diesel generator sets
For the maintenance of diesel generator sets, the phenomenon of hard twisting fasteners with a wrench, or hard knocking fasteners with a hand hammer often occurs. As a result, the diesel engine broke down frequently after installation, and some even caused serious accidents. The important fastene...Read more -
Fault analysis and elimination when there is air in diesel engine oil circuit system
Once the fuel system of the diesel generator has air into it, the light engine is difficult to start or run unstable, and the heavy engine may break down in the road and be embarrassed. Taking the common plunger pump fuel supply system as an example, the various phenomena of air in the oil circui...Read more -
Maintenance of diesel generator set focus
First, in order to ensure the normal operation of the diesel generator set, there should be no accumulation of water, oil and dirt near it, and there should be no corrosive gases to avoid damaging the winding insulation of the generator. While moisture-proof and dustproof, it should be noted that...Read more -
Load characteristics of diesel generator sets
This is actually the load characteristic of the synchronous generator, because it is directly connected to the load. The working principle of the synchronous generator has been explained: after the rotor winding is passed into the DC current provided by the rotating rectifier, a magnetic field is...Read more
