Explain the fault treatment methods and functional characteristics of diesel generators

发表时间:2019-04-11 Article source : Couch motor manufacturersPost time: 2019-04-11

In life, people occasionally encounter circuit faults and then power outages. What should I do when power outages occur? A small diesel generator can help everyone, it can provide stable power energy, and it can also provide power to special equipment. Xiaobian has compiled relevant information about diesel generators, let's take a look next! The following is the introduction of "explaining the diesel generator fault handling method and its functional characteristics".



[How to quickly repair a broken gear of a diesel generator]


After a long time operation of a diesel generator set, there will always be some failure due to wear or other reasons. The method of quickly repairing the damaged gear of a diesel generator set is for your reference.


First, the method of reversing wears the gear tooth surface in one direction. If the structure allows it, you can change the position of the gear or turn it 180 degrees, using the non-wearing side. However, use them in pairs, or replace the matching gears with new ones to ensure the normal meshing of the gears.



Second, the cogwheel tower gear is made of several gears, and the damage of each gear is different. If the gear teeth are worn individually, they can be repaired by replacing the ring gear. The gears to be repaired are annealed first, and all the worn gear teeth are removed, and a gear ring gear is manufactured and press-fitted on the car gear removed portions. In order to prevent the new ring gear from loosening, it can be welded with electric welding spot welding on the circumference of the combination of the ring gear and the gear, or drilled into the nail to fix it.


Third, the cog method For gears with low load and low speed, individual gear teeth can be used to partially update the cog method. Fang Jie repaired the root of the broken gear on a planer or cut out a trapezoidal groove, pressed a new tooth blank with the same groove shape into the groove, welded it and processed it.


Fourth, the surfacing method of individual or several gear oils on the surface wear or tooth end wear on both sides exceeds the limit, etc., according to the gear damage, you can overlay or layer one or more layers on the gear teeth metal. Gear repair can be divided into electric welding and gas welding. Surfacing repair gears are easy to operate and have good repair quality.


Fifth, the screw tooth method is used to remove the toothed gears, clean them, use a vernier to measure the thickness of the tooth root, and use a frustrated knife to flatten and clean the teeth. According to the thickness of the root of the tooth, a screw with a corresponding diameter is selected, and the thread length is not less than 1.5 to 2 cm. Then use a bench drill to drill the hole of the gear to drill a hole with the same diameter as the screw, and then tap with a tap. Tighten the selected screw in the screw hole, then use a hacksaw to saw off the screw that is higher than the top of the tooth, and then use a frustrating knife to process the same tooth shape as the original tooth, and you can use it.


[What are the advantages and performance of diesel generators]


1. Advantages:


(1) When the fuel economy, high thermal efficiency, and operating conditions change, the fuel consumption curve changes relatively flat, and it is economical at low loads.


(2) Reliable and durable. Because there is no ignition system, failures are low.


(3) Wide range of use.



(4) Low harmful emissions.


(5) Good fire safety. Generator automatic voltage regulation includes: thyristor, phase compound excitation, TD1 type carbon resistance automatic voltage regulator, and some use high-power tubes.


2. Features:


(1) Multiple stand-alone capacity levels. International generating units range from several kilowatts to tens of thousands of kilowatts, and domestic generating units of several thousand kilowatts.


(2) The supporting equipment has a compact structure and flexible installation locations (water cooling only needs 1/10 of 34 ~ 82L / KW · H steam turbine).


(3) High thermal efficiency and low fuel consumption (30 ~ 46% thermal efficiency).


(4) It takes a few seconds to start quickly and reach full power quickly. The shutdown process with full due (normal 5 ~ 30MIN) within 1 minute of emergency is short, and it can start and stop frequently.


(5) Simple maintenance operation, few people, easy maintenance during standby.


(6) Comprehensive cost of construction and power generation of diesel generators.


The above introductions on "How to quickly repair broken gears of diesel generator sets" and "What are the advantages and performance of diesel generators", I hope that you can understand the "explaining diesel generator fault handling methods and their functional characteristics" to help .

    Before starting, you should check whether the fuel volume of the fuel tank is rich, and there is no oil leakage in each oil pipe and the discussion area; whether the cooling system water is rich, clean and leak-free, and whether the fan belt is tight or not. The internal combustion engine and generator drive parts should be connected and trusted. The wires of the input line are well-insulated, complete and effective in all aspects. After starting, it should run at low speed for 3 to 5 minutes. After the temperature and oil pressure wheel are normal, the initial work can be done. The generator should be no different in the speed increase. Ring, the slip ring and commutator are well brushed, no jumping and sparking phenomenon. After the operation is stable and the frequency and voltage reach the rated value, power can be supplied to the outside.

    Blue smoke, fire reason: It means that the engine is burning oil. There are three types of reasons: first, the piston ring goes opposite, and the oil comes in the cylinder; the second is the oil level of the oil pan of the atmosphere filter, which leads the ring. The height of the groove; Third, the gap between the duct and the valve stem is too poor. Expulsion idea: Adjust the piston ring so that the opening teeth of the ring are staggered 120 degrees or 180 degrees, and the opening teeth of the ring should avoid the piston pin hole and the side pressure is poor. Adjust the height of the oil level of the oil filter of the atmosphere filter below the height of the annular groove; if the clearance between the duct and the valve stem is too poor, replace the component and reduce the clearance. The normal mutual assistance clearance between the two is 0.0

At present, the diesel generator set maintenance market refers to damage inspection and routine maintenance. Two aspects: after maintenance refers to the failure of the diesel generator, there are problems with various accessories, such as replacing the generator or

    The diesel engine is working normally, but the generator fails to generate electricity or the voltage is very low. This may be due to the components associated with the generator, such as: the exciter is damaged, and the excitation voltage cannot be supplied. The excitation current is taken in. The rotor's dead center residual magnetism is weakened or declining. It will make the generator unable to generate electricity or the transmission voltage is extremely low. The right to respond is usually: use an appropriate DC voltage and directly connect to the excitation winding according to the polarity Magnetization. Carefully inspect the exciter and the cyclotron rectifier, find abnormal components or windings, and replace them for restoration. The generator's transmission voltage is unstable, and
