Diesel Generator Tech

  Since January this year, the southern region has suffered from continuous rainy weather. Improper handling of diesel generator sets during use is prone to moisture problems, especially the damping of the motors of the generator sets, which has a great impact on the life and work of the generator sets. At this time, the user must dry the damp diesel generator set . For the relevant drying method, the user can refer to the following methods: 1. Short-circuit the three-phase outlet of the stator winding and connect it firmly. 2. Adjust the resistance of the voltage regulating rheostat in the excitation circuit to the maximum value. If the resistance value is not enough, add another resistance to increase the resistance value. 3. Start the generator set , slowly increase it to the rated speed, and then slowly adjust the excitation current. The excitation current is determined according to the damp condition of the generator set, and the short-circuit current of the stator ...

As a user, I believe that when you purchase a diesel generator set, the generator manufacturer must have emphasized to you that you need to maintain the diesel generator set regularly, so you know why it is very important to maintain the diesel generator set regularly. Is it important? In this article, Jiangsu Starlight Electricity Equipments Co.,Ltd. will tell you the reasons for this from the engine oil. Most people don't know that engine oil can degrade over time even when the engine is not running at all. If the life expectancy is 1 year, it doesn't mean it can maintain 100% quality in a year. It started to degenerate from day one, but still reached acceptable tolerance levels after a year. Now, if you extend your service interval to 18 months, that doesn't mean your oil is half as good as new, because you've exceeded the recommended 50% change. Oil does not degrade linearly, which means it may retain its usefulness and then suddenly lose 90% of its l...

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...

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 ...

Operation and Maintenance Manual of Weichai Deutz 226B Series Generating Engine Special Attention *In order to protect your legal interest, it is forbidden to dismantle the fuel pump lead seal optionally. *If the injection pump were adjusted or lead seal were removed, the quality guarantee of the company would become invalid immediately. *We would not provide free service for the dismanded injection pump. *Turbocharger rotor shaft is of precise part, forbid disassembling and colliding, Otherwise the quality guarantees of the company will be of invalid. *There are strict torques and turn angles for the main bearing bolts and connecting rod bolts, Users don not loose and dismantle them, otherwise the quality guarantees of the company will be of invalid. *Before starting the engine. check coolant and oil whether they are filled up or not. *Connecting rod bolt cant he reused. *Meaning of identification : *Exhaust gas contains noxious composition, therefore it mu...
