Explain the fault treatment methods and functional characteristics of diesel generators
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 electrical energy and 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, the gears are used in pairs, or the matching gears are replaced 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 worn gear teeth are removed from the car, and a gear ring gear is manufactured and press-fitted on the parts of the car. In order to prevent the new ring gear from loosening, it can be welded with electric welding spot welding along the circumference at 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 tooth on a planer or cut out a trapezoidal groove, and pressed a new tooth blank with the same shape as the groove into a certain tightness, welded it, and processed it for shaping.
Fourth, the surfacing method of individual or several gear teeth oiling surface wear or tooth end wear on both sides exceeds the limit, etc., according to the gear damage, you can overlay or add one or more layers on the entire or part of the surface of the gear teeth metal. Gear repair repair can be divided into electric welding and gas welding. Surfacing welding repair gears are easy to operate and have good repair quality.
Fifth, the screw tooth method is used to remove the toothed gear, clean it, use a vernier to measure the thickness of the tooth root, and use a frustrated knife to flatten and clean. 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 cut off the screw that is higher than the top of the tooth, and then use a frustrating knife to process the same tooth as the original tooth, and you can use it.
[What are the advantages and performance of diesel generators]
(1) When the fuel economy, high thermal efficiency, and operating conditions change, the change in the fuel consumption curve is relatively flat, and it is also 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 forms are: thyristor, phase compound excitation, TD1 type carbon resistance automatic voltage regulator, individual high power tube.
(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 .
- The use and realization of diesel generators has also changed in different weather and temperatures in different seasons. So, how to make a diesel generator safely through a season in the process of using a diesel generator? Here are three suggestions. In the manual of the lubricating oil unit, there are no special requirements for oil, and there is no "winter or summer".
- Matters needing attention when assembling diesel generator sets: before use, it can effectively avoid unnecessary damage to the equipment, and it is easy to transfer moisture to the equipment. Attention should be paid to the assembly of the generator set and equipped with lightning protection devices. The reliability of the two-way switch wiring needs to be reviewed by the local power supply department, and the pipeline should be lowered by 5-10 degrees. If the assembly environment is wet, the generator housing must be reliably grounded and the pipe diameter must be the muffler or outlet diameter.
- The rental of diesel generators is the supplier of emergency backup power after a power failure. Most of the units are in standby mode. Once the power is cut off, it is necessary for the unit to "start in an emergency and supply power in an emergency" or the backup unit will lose its meaning. The starter battery of the unit is unprotected for a long time. The electrolyte water does not increase in real time after the water of the electrolyte evaporates. It is not equipped with a starter battery charger. The battery's power decreases after natural discharge of the battery for a long time. Charge / float charge switching. In view of the negligence of the failure to perform the switching control, the battery power cannot meet the conditions, except for handling this exception.
