Dongguan ShangXi Chai Electrical Equipment Co., Ltd. specializes in the world of various brands of generator sales, leasing, maintenance, sale and other related facilities and services. Focus on business: Dongguan generator rental, generator maintenance, Dongguan, Dongguan generator sale, used generators Dongguan, Dongguan generator maintenance. Modern telecommunications companies in the city because of their industry characteristics, running communications equipment must be foolproof. Switches and other communications equipment in order to ensure uninterrupted operation, and more generally the use of diesel generators as their backup power, once the mains power failure occurs, immediately start the diesel generator, switch the mains / oil machine conversion screen (ATS) provide power for communications equipment by diesel generators, in order to protect the normal operation of telecommunications services. Because the majority of the telephone office in densely populated areas, these areas is very high demands on the environment generator rental, and diesel generator set to become the main source of noise is often ambient noise. Current society increasingly demanding environment, how to effectively control the noise pollution is a difficult, but also has great promotional value of the work, which is a major work of our communication construction should get more attention . In order to do this job generator rental Dongguan factory, the first diesel generator noise to understand and analyze the composition. A sound source analysis of diesel engine noise is complicated by a variety of sound sources of a noise source, according to the noise emission mode, the diesel engine noise can be divided into the aerodynamic noise and surface radiation noise. Produced in accordance with the mechanism, diesel Surface Noise can be divided into the combustion noise and mechanical noise. Where the aerodynamic noise is the main noise source. 1.1 aerodynamic noise is aerodynamic noise due to non-stable process gas, i.e., by the interaction of the disturbance and the gas in the gas and the object generated. Aerodynamic noise radiated directly into the atmosphere include: intake noise, exhaust noise, the cooling fan noise. Generator Test Procedure Step 1: Check the generator each site with or without external wires break, wrong connection, short circuit and measuring point whether the battery voltage B + with a voltmeter. Step two: the key to the door down with the "on" position, but do not start the engine, this time with a voltage meter to measure D + point whether the voltage, the charging light is bright and observe. The third step: Start the engine generator rental Dongguan Mobile, with a voltmeter to measure the voltage at point B + engine diesel generator rental Dongguan, should reach the following values ??12V system voltages above 13V while subtraction throttle, Voltage 24V system voltages above 27V fourth Step Three: Open the partial load, such as lights 12V system voltages above 13V while subtraction throttle, Voltage 24V system voltage changes over moderate 27V Step Five: Open air conditioning, lights and other major electrical system voltage of 13V 12V or more at the same time throttle acceleration voltage of 27V 24V system voltage greater degree of change over to the third step, the generator is no voltage output, may take the following measures to check, for a generation of generator excitation D + points such 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 point D + (1S less time), then voltmeter B + point whether the voltage output, if any, from The third step is to start checking the fifth step, determine the vehicle while charging indicator lines are open circuit (usually damaged lights, dashboard lever to pieces loose, circuit breaker), the absence of a voltage output, the generator does not exist power failure.
