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 -
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 -
How does small diesel generator set save fuel
How does small diesel generator set save fuel Small diesel generator sets want to save fuel have the following points to pay attention to: 1, small diesel generator fuel purification: diesel contains a variety of minerals and impurities, if not precipitated filtration purification,...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 -
The correct operation and maintenance of diesel oil pump are introduced in detail
1, before the installation of the oil pump, check whether the model and specifications are correct, and remove the anti-rust oil, the thickness of the selected gasket should be appropriate to prevent too thin or too thick and make the piston top dead or not run in place, tighten the bolt torque s...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
