A,Generator controller The development history, automation control relay control will be very complex of peripheral circuit integration in a module.Greatly simplifies the control circuit, the reliability is improved, more human, there are also some generator manufacturers in the production of small gasoline engine all-in-one, practical and convenient.

Two diesel generating set, diesel generating sets structure consists of three parts: engine, generator and generator controller.Power of engine, the engine's mechanical energy into electric energy by generators.Generator controller is part of the brain that generator set, not only provide the engine starting, stopping, data measurement, data display and fault protection function, but also provide the generator power, and power measurement of display and power protection, and other functions.

Three types, generator controller is intelligent controller can be broadly divided into simple protected (i.e. only provides start-up, shut-down and high temperature, low oil pressure, overspeed protection. Do not provide power, according to the control panel is needed to install water thermometer, the oil pressure gauge, hour meter, battery voltmeter, ac voltmeter, ac current meter and other meters) standard (provide power display, protection function, without communication interface) high-grade model (in addition to providing standard function, but also can provide communication interface, can be carried outRemote control, remote sensing, remote communication function.Some also have a network interface, can be monitored via the Internet, and some have text function, is suitable for remote areas of unattended engine room).

Four, diesel generating sets of commissioning inspection steps of the diesel generating set when the choose and buy, the customer most concerned or generating set prices.Generating set according to the points, there are many kinds of brand, and different power of the diesel engine generator set price is different also, diesel generator set manufacturer how to introduce diesel generating sets the price for you to compare.

Asking?Ask about the purchase time of diesel engine, ask about the repair of the past, replacing the what are the main parts.What's the problem between polling in use.In order to understanding of the old diesel engine has a more comprehensive system.

2 see signs of the old diesel engine and appearance.Look at is which factory production.When leaving the factory, the distance how long is it?The appearance of the paint is peeling, department whether defects, machine is to be eliminated, etc.From the sign to distinguish old diesel engine condition and appearance.

Three for commissioning.Through the rocking-turn crankshaft, throw the flywheel, starting the machine, etc.A more careful check of the old diesel engine.Commissioning is a very important step to specific inspection steps are as follows:

1, rocking-turn crankshaft, make two mouth by mouth.Such as sound like the coo of a two made by mouth mouth, mouth two by mouth and plunger vice performance is good, such as wheel indoor no "wow" the abnormal noise, then gear wear and tear is not serious.

2, touch the mouth up and down throw flywheel without noise?That crank shaft between the stem and bearing clearance is not big.

3, pull to turn the flywheel, the piston is close to the check point?Then move the flywheel?If there is no "clicking" sound?The wear between the connecting rod shaft stem and tile not serious.

4, make the cylinder pressure, turn the crankshaft, touch the mouth piston when removing decompression of rebound, flywheel rapidly rotating?Cylinder, piston, piston ring wear small.When the rocking-turn crankshaft, engine oil pressure gauge pointer should be not less than, or oil instructions red mark rises quickly and under pressure should be easy.

5, starting the machine.Such as easy to start, smoke colorless or light gray, speed stability without noise, that old diesel engine technology condition is good.Note, side try process of diesel generating sets, all the best in the diesel generator controller to operate and tracking detection the variations of air pressure, oil pressure, etc.?Is very tall to the requirement of design humanization, etc?This kind of controller, currency field evaluation is very high, five, how to choose and buy diesel generator set enterprise when diesel generating sets of choose and buy?Should pay attention to what problem, diesel generating set is widely used in telecommunications, financial department, hospital, school, business and other departments, industrial and mining enterprises and other special purposes of independent power supply.Enterprises in the choose and buy diesel generator set have their own standards.
