Step 1: Check the generator outer wires each site with or without break, wrong connection, short circuit, and measure whether the battery voltage B + point second step with a voltmeter: the key to the door down with the "on" position, but do not start the engine , this time with a voltage meter to measure whether the voltage D + points and see the charging indicator bright. The third step: start the engine, with a voltmeter engine B + point voltage, should reach the following values ??above 12V system voltage of 13V while subtraction throttle, Voltage 24V system voltage change is a little more than 0.1 ~ 0.2V 27V Step four: Open part load, such as lights, 12V system voltage is more than 13V while subtraction throttle, Voltage 24V system voltage changes moderate 0.2 ~ 0.4V 27V above fifth step: open air conditioning, lights and other major electrical system voltage of 13V 12V At the same time more than plus or minus throttle, Voltage 24V system voltage of 27V or more have a greater degree of variation from 0.5 to 1 to the third step, the generator is no voltage output, may take the following way to check, for a generation generator excitation D + point as 27 series, 23 series, 29 series, 19 series battery positive lead from a 2.5mm2 wire, after starting the engine, with the other end of the instant click D + point (time 1S or less), then the voltmeter whether the voltage output point B + if so, starting from the third step to the fifth step inspection, while the vehicle is determined that the charge indicator lines are open circuit (usually damaged lights, dashboard lever fittings loose, circuit breaker), the absence of voltage output, then there is not a power generator fault. A: generator rental lease: Designed for: Project electricity, temporary power plant outage restaurants, performing arts and shooting fill power, corporate events electricity, showcase lighting electricity, the generator voltage 220/380 {}, {50} Hertz, power; 5KW 20KW 30KW 50KW 75KW 80KW 100KW 120KW 150KW 200KW 220KW 250KW 300KW 350KW 400KW .500KW 550KW 600KW 720KW 800KW 1000KW 1200KW, ordinary type, silent type, mobile type, vehicle type are brand; Daewoo, Cummins, Volvo, Caterpillar, Mitsubishi, took the lead and the like. II: automotive pump: Main concrete pump rental, drag pump, pump car, truck crane; I have a concrete pump more than 20 Taiwan, drag pump 35 units, automotive pumps pump more than I used. chassis VOLVO, Mercedes Benz, Isuzu, Hino and other (37 m -56 m), advanced pumping configuration, greatly enhancing the pumping efficiency of the pump. And the swing is small, high stability, safe and reliable. Three: Repair Diesel: repair generators, diesel engines, on firewood, Weifang, Daewoo, Volvo, Cummins generator sets IV: Pneumatic series: air compressor (7 kg 10 cubic meters, 7 kg and 17 cubic meters, 7 kg 19 cubic meters, 10 kg 21 cubic meters, 28 cubic meters 18-21 kg, 24 kg 34 cubic meters, equipment, mainly Japan ALRMAN, original Ingersoll) five: diesel generator units accessories: The company has a factory on the wood, Weichai generating units accessories, quality guaranteed! Allowing you to use comfortable, according ease! Six: Professional to do maintenance on the diesel generator set: Seven: Professional sales of diesel generator sets: Major: Cummins generators, Volvo generators, Daewoo generator set, silent generator set, mobile power station generators. Import and domestic; mute and bare; the company diesel generator mechanic, diesel generator maintenance workers all through professional learning and training. Successfully partner: The Company Railway, built in tunneling, construction, municipal and other construction units have a good cooperation, South Station construction, subway construction, venue construction, venue and emergency backup machine, bank guarantee electricity, hotels and Hotel (Beijing Hotel) (East Chang An Hotel), and so are our partners. The company is now Beijing \ Tianjin \ Hebei \ Henan \ Shanxi \ Northeast and other places with offices. It can be widely used in highways, railways, airports, factories, hospitals, ships, buildings, communications, mining, pipeline cleaning, construction machinery, stage, lighting and sound, and other fields, is the ideal slogan construction unit, the leasing company or individual:
