Talk about the new characteristics of diesel generator set
Now the important equipment generator set for the computer room, with the different requirements of other equipment for power supply, there is a great development. Combined with their own experience, the direct selling network has made a systematic summary of its new characteristics and developme...Read more -
Three purposes of grounding diesel generator sets
In order to ensure personal safety and the needs of the power system, there are strict requirements for the grounding of the diesel generator set. There are three kinds of grounding methods: working grounding, protection grounding and protection zero. The purpose of grounding is as follows: 1. G...Read more -
The shaft current of the generator causes damage to the bearing or rotor system
In the rotor system of the rotating machinery of the generator, the parts that are prone to EDM discharge are the bearing surface of the radial bearing and thrust bearing, the working tooth surface of the gear coupling and the sealing surface of the floating ring. Due to various conditions in ope...Read more -
The clever wrapping of the generator insulation
According to the layering method of wrapping tape, insulation wrapping can be roughly divided into three types: layering, layering (half layering) and flat wrapping. When wrapping, the wrapping method of the tape should be distinguished according to different parts and needs. The dip Angle of the...Read more -
How to find the leakage point and plugging of diesel generator set
The fuel supply system of the diesel generator set has a low pressure oil circuit and a high pressure oil circuit, the low pressure oil circuit refers to a section of the oil circuit from the tank to the low pressure oil chamber of the injection pump, the high pressure oil circuit refers to a sec...Read more -
Diesel generator set oil pump maintenance
The role of the oil delivery pump is to ensure that the diesel oil circulates in the low pressure oil circuit, and to ensure that a certain amount and pressure of diesel oil is transmitted to the injection pump through the diesel hose and the diesel filter. In order to prevent the failure of the ...Read more -
Basic requirements for the use and maintenance of diesel generator sets
Diesel generator set in each unit using are generally used when mains power failure emergency, the daily maintenance of diesel generator set at a crucial moment has a close relationship with can really play a role of emergency, so use personnel must do daily maintenance work, always keep the dies...Read more -
The main reasons and matters needing attention for the reduction of compression ratio of diesel engine
The compression ratio is the ratio of the total cylinder volume and the combustion chamber volume of the diesel engine, and its change not only affects the power and economy of the diesel engine, but also affects its starting performance. In the design of each diesel engine has stipulated a good ...Read more -
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
