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 -
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
