The new county where the sale of the generator

The new county where the sale of the generator because the capacitor charge and discharge will lead to small fluctuations in supply and crew oscillation generator (English name: Generators) are the other forms of energy into electrical energy machinery and equipment, which consists of turbine, steam turbine, diesel or other mechanical drive power, the energy of water, air, fuel combustion or nuclear fission produced by the generator into mechanical energy to pass, then converted to electricity by the generator. Generating a wide range of uses in industrial and agricultural production, national defense, science and technology and everyday life. Form generator a lot, but it works it is based on the law of electromagnetic induction and electromagnetic force laws. Thus, the general principles of its structure is: with the appropriate magnetic and conductive materials with each other electromagnetic induction magnetic circuit and a circuit to produce electromagnetic power, to achieve the purpose of energy conversion. Generators usually consists of a stator, a rotor, a generator must also be given sufficient air cooling generator cover and bearing member. The stator by the stator core, line package winding, base and other structural elements of a fixing these. Rotor from the rotor core (or magnetic pole, magnetic brief) windings, retaining ring, center ring, slip ring, fan and shaft and other components. The bearing and cover the generator stator and rotor assembly connected together, so that the rotor can rotate in the stator, doing sports cutting magnetic field lines, resulting in EMF, leads through the terminal, connected to the loop, it generates a current. ◆ airflow from the start and cabinet can control two or more diesel generators and vehicle operation of the system has the following significant advantages: first start success rate> 99%) ◆ The system uses the deep 7510 British intelligence module, when the power cut After (or other unit start signal) by the delay confirmation (0-30S adjustable) unit automatically start (1-8 times adjustable, for the first time success rate of start> 99%) normal automatic confirmation generator power, power to the load . Therefore ◆ Mains returns to normal, the control module receives a signal issued a directive by the delay confirmation (0-30S adjustable) Automatic (cooling down time is 0-300S adjustable) but its working principle is based on the law of electromagnetic induction and electromagnetic Law ◆ Intelligent power module system with full LCD display in English, the control panel digital display of voltage, current, frequency, running time, battery voltage, convey speed and other relevant parameters. At the same time in the internal FLASH memory memory from the start from stop Shelter: intelligent all-Chinese liquid crystal display control module, when the electricity blackout, confirmed by the delay (0-30S adjustable), the crew from the start (1-8 times can After the transfer, the success rate of the first start of> 99%) confirmed automatically after power generators normal power to the load, electricity back to normal, after delay confirmation (0-30S adjustable), automatic shutdown cooling (cooling down time 0- 300S adjustable). Units from the start (1-8 times adjustable ◆ Protection: Low / speeding, failure to start, the water temperature is too high, the output voltage faults (overvoltage, undervoltage, overcurrent) to produce electromagnetic power ◆ interface operation: Auto / Stop . / Manual function selection, emergency stop buttons, buzzer and mains float is customary for the expression of transformers and UPS (UPS is the English abbreviation Uninterruptiable Power Supply ◆ alarm indication: low / overdrive, the output voltage fault, failed to start High temperature pre-alarm setting function: it allows the user to change the set parameters memorized in the internal FLASH memory, when the system is powered down it will not be lost, the controller, all parameters can be set on the front panel II. , diesel generator apparent power relations, active power, rated power, maximum power, economic power between? A: 1. The unit of apparent power KVA diesel generator basics classes are: (1) oil lubrication system; (2) fuel system; (3) control and protection system; (4) cooling cooling system; (5) the exhaust system; (6) the starting system on the basics of diesel generator sets and the like, there are many users are not very clear This paper will users often have major doubts do answer a few questions, I hope this can be helpful to a user, the basic equipment diesel generating sets, including what system? Answer: diesel generator set includes a six systems, diesel power generation The basic equipment units, including what system Answer: diesel generator set includes six systems are:? (1) Oil System; (2) fuel system; (3) control and protection system; (4) cooling cooling system; ( .? 5) exhaust system; (6) Starting System II, diesel generator apparent power, active power, rated power, maximum power, the economic power relations A: 1 unit of apparent power KVA, in China. habit for expression of transformers and UPS (. UPS is the English abbreviation Uninterruptiable Power Supply, translated uninterruptible power supply) whose basic function is to: City electricity interrupted supply, uninterrupted power supply capacity .2 active power apparent power 0.8 times, the unit is KW, our habits for power generation equipment and electrical equipment. 3. diesel generator rated power refers to 12 hours of continuous operation power. The maximum power is 1.1 times the rated power, but 12 within hours to allow only the use of one hour. Three, 5. Economic power is 0.75 times the rated power, diesel generator sets no time limit can be long-running output. In the power operation, the fuel most provinces, the lowest failure rate. Users want to be able to help three, the best use of power generators (economic power) how to calculate the answer:? P best = 3/4 * P rated (ie 0.75 times the rated power) Fourth, the three-phase generator power To improve the power factor is the number of factors that can add power compensator it A:?? power factor of 0.8 can not be, because the capacitor charge and discharge will lead to a small power fluctuations and crew oscillation. Fifth, why the new machines need to be replaced after a period of oil and oil filter? A: Because the new machine in the running period inevitable impurities into the machine sump, so that the oil and oil filter physically qualitative or chemical qualitative change. Sixth, why install diesel generators, the exhaust pipe to downward 5-10 degrees? A: The main is to prevent rainwater from entering the exhaust pipe, causing a major accident. VII. Why ask diesel generator site must use air flow? A: The output of the diesel engine is directly affected by the amount of air intake and air quality, the generator must also be given sufficient air cooling. So the use of air space must be smooth. Eight, how to identify counterfeit and shoddy domestic diesel? A: First check whether the factory certification and product certification, they are diesel engine factory "; identification";, it is a must have. Then check the three number 1 plate number on a certificate; 2. the serial number (the kind usually in the flywheel mechanical cutting off the plane, the font is convex body); 3. Pump plate number. Check this actual number three on the number of diesel engine, must be accurate. If there are doubts can verify these three numbered newspaper factory. Nine, why not let the diesel generators run long in the case of less than 50% of rated power. A: Because if less than rated power at 50% of the cases, the diesel generator oil consumption increased, easily coking diesel, increased failure rate, shorten the repair cycle.
