Yanshi where the sale of the generator

Yanshi where the sale of two generators, diesel generator apparent power, active power, rated power, maximum power, economic power relationships? A: 1. The unit of apparent power KVA generator (English name: Generators) are other forms of energy into electrical energy machinery and equipment, which is driven by a turbine, steam turbine, diesel or other power machinery, the water, air, fuel combustion or nuclear fission energy produced by the generator into mechanical energy to pass, and then converted into electricity by a 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, namely: (1) Oil System; (2) fuel system; (3) control and protection system; (4) cooling cooling system; (5) the exhaust system; (6) starting system 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. First, the basic equipment diesel generating sets, including what system? A: The diesel generator set includes six systems from the start and cabinet ◆ can control two or more diesel generators and vehicle operation of the system has the following significant advantages: users want to be able to help ◆ The system uses the British deep sea 7510 intelligent modules, when power cut (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%) confirmed automatically generating After normal power supply unit, power to the load. This article will users often have several questions to answer doubts do ◆ main electricity returned to normal, the control module receives a signal issued a directive by the delay confirmation (0-30S adjustable) Automatic (cooling down time can 0-300S tune) a lot of users are not very clear ◆ intelligent module system with full LCD display in English, on the control panel digital display of voltage, current, frequency, running time, battery voltage, convey speed and other relevant parameters. Basics class diesel generator diesel generator on the basics of the class from the start from stop Shelter: intelligent all-Chinese liquid crystal display control module, when the electricity blackout, after delay confirmation (0-30S adjustable), the unit Since start (1-8 times adjustable, for the first time success rate of start> 99%) confirmed automatically after power generators normally, power to the load, electricity back to normal, after delay confirmation (0-30S adjustable), automatic Shutdown cooling (cooling down time 0-300S adjustable). Controller All parameters can be set on the front panel ◆ protection function: low / speeding, failure to start, the water temperature is too high, the output voltage faults (overvoltage, undervoltage, overcurrent). When the system is powered down it will not be lost ◆ Interface Operation: Auto / Stop / Manual function selection, emergency stop buttons, buzzer and mains floating device. At the same time in the internal FLASH memory Memory ◆ alarm indication: low / overdrive, the output voltage faults, launch failure, high temperature pre-alarm. Setting Function: Allows the user to change setting its 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. The stator by the stator core, line package winding, base and other structural fixing these parts diesel generator class composition basics Generator is usually about class diesel generator stator, a rotor, a generator cover and bearings and other components the basics, there are a lot of users are not very clear, the paper will have a few problems users often make major answer doubts, users want to be able to help. To achieve the purpose of an energy conversion, basic equipment diesel generating sets, including what system? A: The diesel generator set includes six systems are: (1) Oil System; (2) fuel system; (3) control and protection system; (4) cooling cooling system; (5) the exhaust system; (6 ) starting system. Second, the apparent relationship between diesel generator power, active power, rated power, maximum power, economic power between? A: 1. The unit of apparent power KVA, our habits for transformers and UPS express its basic function is (UPS is the English abbreviation Uninterruptiable Power Supply, translated into an uninterruptible power supply.): When the mains supply interruption, can not uninterruptible power supply capacity. 2. The active power is 0.8 times apparent power, 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 within 12 hours using only allow one hour. Third, 5. Economic power is 0.75 times the rated power, diesel generator sets no time limit long-term operation of output power. In the power operation, the fuel most provinces, the lowest failure rate. To produce electromagnetic power three, the best use of power generators (economic power) calculated? Answer: P best = 3/4 * P rated (ie 0.75 times the rated power) four-phase generator power factor is how much? To improve the power factor can be added to power compensator it? A: The power factor of 0.8. No, 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.
