Diesel Generator Tech

Principle: The theory is to synchronize two generators so that they can both supply the same load. Their output voltage, frequency, and phase are matched so they can operate in parallel which will add the capacity of the second machine to the first. Once in sync, they will tend to keep each other in sync and if one generator engine shuts off or fails to keep up, the other will run that generator as a motor, quite possibly damaging the alternator and engine. Use generators that have manual controls to adjust engine speed (frequency) and voltage. The generator receptacle panels should each have a 120-volt convenience outlet to use as the alternator leads to sync the generators. The larger 120/240 volt 30 or 50 amp receptacle is used to parallel the generator outputs and supply the load and must have its own breaker to turn the output on and off. This is breaker referred to below. 120/240 volt generators have two hot leads and one neutral. One lead is L1, the other is L2

Exhaust turbocharger is actually an air compressor that increases air intake through compressed air. It uses the inertial impulse of exhaust gas from the engine to push the turbine in the turbine chamber, the turbine drives the coaxial impeller, the impeller compressed the air from the air filter pipe to pressurize it into the cylinder. The increased air pressure and density entering the cylinder can burn more fuel, accordingly increase fuel amount and adjust engine speed, which can increase the output power of the engine. Turbochargers are based on the principle of forced induction. It is the process of forcing compressed air into the intake for combustion. PARTS OF TURBOCHARGERS A Turbocharger consists of - 1.) COMPRESSOR HOUSING 2.) COMPRESSOR WHEEL 3.) BEARING 4.) OIL SEALS 5.) SHAFT 6.) TURBINE WHEEL 7.) TURBINE HOUSING The middle part whole part together is called a turbocharger cartridge. The compressor wheel and the turbine w

2.1 Gear system and valve mechanism of Weichai Power Generation   Diesel Engine The valve mechanism comprises camshaft gear, camshaft, tappet, push rod and valve train, and it adopts a structure of overhead valve and underneath camshaft. Camshaft gear1 is driven by crankshaft gear 6 through idle gear 2, and crankshaft gear 6 also drive fuel injection pump 3 through idle gear 2.The gears should be assembled according to the paired engagement marks. Each gear is marked with “.”, and the gears must be assembled with “.” marks aligned to ensure that the valve timing and fuel supply time are correct, as shown in Figure 2-1. Driven by the camshaft gear, the camshaft controlsthe opening and closing of intake and exhaust valves according to certain valve timing through the tappet and push rod. 2.2 Lubricating system Lubricating system consists of oil strainer, oil pump, oil filter and all internal pipes. The diesel engine adopts a combined lubrication method: pressure lub

Deutz recently decided to increase its presence in the Middle East thanks to the help of its network. Deutz dealers and service outlets in the Middle East are the real makers for the implementation of this growth strategy for the service business. Michael Wellenzohn, member of the Deutz Board of Management,said: «Expanding and digitalising our service activities forms a key part of our growth strategy. By building on our presence in the Middle East, we will be better able to meet regional demand for our products and services, which will not only make our local operations much more efficient, but will also significantly improve the performance of the service business as a whole». Matthias Szupories, Regional Head of Western & Southern Europe, Middle East & Africa, added: «A Bahrain-based partner with a strong presence in the region will serve as the main importer for the several of the Arab Gulf States. The local parts and servicing activities will be expanded and man

In order to ensure effective and normal running of your engine, before using Weichai power generation engine, please carefully read the content below: It is required to do running-in of complete engine and operate the engine according to the regulations in these instructions, and come to "Three Guarantees" places appointed by Weichai company for "Mandatory Service" with specified period (or trip distance). It is now allowed to stop the engine running at high speed or with full load suddenly, instead, the engine should be stopped after running at idle speed for several minutes. Before every start-up of the diesel engine, it is required to check if it has been filled up with coolant, and if enough oil has been added. It is required to use the fuel, oil and coolant according to these instructions. Connecting parts of air intake pipeline must be sealed well, and there should not be any crack, sand hole or damage on all kinds of pipes.There should

There are a few reasons why synchronous generators are used to supply electric power Constant Voltage. Constant frequency. Capability to deliver active as well as reactive power. Appropriate synchronization between all alternators to an infinite bus bar (V=1<0 p.u constant). Various generators from across the country synchronize with this infinite bus which can supply electric power from anywhere in the country. This has flexibility to increase the number of generating units synchronized with the infinite bus bar. On the other hand if we use induction generators instead of synchronous generators, there will be two aspects Reactive power requirement of I.G 2. Harmonic content in output power spectrum. The I.G requires reactive power for its operation which needs to be provided either by capacitor banks or I.G. units must be connected to a stable grid where reactive power is available. If we use I.G’s for generation of electric power we will have

The harsh working environment and people's actual needs are all difficult problems for marine generator sets. It is also the test for engine.

1.Assembly of Cylinder Block of Cummins 6BT Series generator engine A.Before assemble, should clean cylinder block. All oil passages, main bearing holes, camshaft holes, tappet holes and screw holes shall not have burr edges, and shall be blown clean with compressed air. No foam, moulding sand and iron chips. Wash with gasoline and white silk cloth until the cylinder and other moving parts are cleaned by sticking machine oil with toilet paper. There is no dirt on toilet paper that the cleaning is qualified; B.Press bowl plug into water jacket hole and main oil passage hole of cylinder block, before pressing, should uniformly smear GY-255 anaerobic adhesive on the surface of bowl-shaped plug cylinder; C.Main bearing head and cylinder block must be paired and assembled. The chambered side of the main bearing cover (marked in sequence) faces the pump side. Each bolt hole of the main bearing cover has a positioning ring for location. Should keep the joint surface of bearing c

The reason why generators overspeed is generally because the oil pump or electronic actuator is stuck, which causes the throttle to reach the maximum position. 1. Diesel generators are small power generation equipment, which refers to the use of diesel oil as fuel. A power machine that uses a diesel engine as the prime mover to drive a generator to generate electricity. The whole unit is generally composed of diesel engine, generator, control tank, fuel tank, storage battery for starting and control, protective device, emergency cabinet, etc. 2, in the cylinder of diesel engine, The clean air filtered by the air filter is fully mixed with the high pressure atomized diesel fuel injected by the injector. Under the extrusion of the piston upward the volume shrinks and the temperature rises rapidly to reach the ignition point of the diesel fuel. Diesel fuel is ignited, the mixture gas burns violently, the volume expands rapidly, pushing the piston downward, called'do the wor
