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 -
Low voltage grounding equipment of diesel generator set
Low-voltage grounding equipment is mainly used in low-voltage diesel generator sets, thermal power plants, coal production enterprises, starting and braking power and other resistance equipment. Here we talk about the role of the low-voltage grounding complete set of diesel generators working in ...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

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 -
What are the characteristics of parallel diesel generator sets
With the increasing power requirements of users on diesel generator sets, the technology of diesel generator sets is becoming more and more mature, and many users choose to use multi-machine generator sets as backup power sources considering the cost. So, what are the characteristics of diesel ge...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 -
Diesel generator crankshaft and repair points
Diesel generator crankshaft and repair points: Engine in the work, the crankshaft due to the force and complex working conditions, the friction profile of the sliding speed is very high, and the heat dissipation conditions are poor, therefore, the crankshaft not only easily wear, and will also s...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 -
How to deal with generator excitation loss
Symbol of generator after magnetic loss: (1) The stator current and active power of the generator rise rapidly after an instant decline, and the ratio increases, and begins to swing. (2) After the generator loses magnetism, it can also produce a certain amount of active power, and keep the direct...Read more
