A heavy duty diesel generators sets an optional basis
1 The chosen diesel generator performance and quality must meet the relevant standards Diesel generatorsare trusted in telecommunications , finance departments, hospitals , schools , business along with departments, industrial and mining enterprises and residential emergency backup power , military and field operations , vehicles and vessels and also other special purpose independent power . Diesel generator sets because communication must reach GB2820-1997 in G3, or G4 level requirements , and also to "Communication heavy duty diesel generators set network quality certification testing implementation details" provided 24 performance requirements , while through our industry department established communication power equipment quality Supervision and Inspection Center of rigorous testing . To be a military communications heavy duty diesel generators sets , you will need to satisfy the relevant GB2820-1997, GJB relevant standards and force departments to produce a " communication power equipment, quality testing standards " requirement, and the organizations concerned departments through strict quality inspection equipment .
2 . Heavy duty diesel generators sets ought to be chosen being considered a significant component Find the unit main factors that should be considered mechanical and electrical performance , the machine uses, load capacity and variety of automation functions.
(1) the employment of it . As heavy duty diesel generators sets can be utilized in accordance , including three varieties of backup and emergency situations . Therefore, different uses of diesel generator sets demanded differ.
( 2 ) load capacity . Needs to be selected in line with different uses load capacity and load range , determine the stand-alone diesel generator set machine capacity and standby diesel generator set capacity .
( 3 ) the usage of crew environmental conditions ( mainly refers to the altitude and climatic conditions )
( 4 ) the option of diesel generators
( 5 ) the choice of the generator and excitation mode
( 6 ) diesel generators automation function selection
3, the noise Engine and generator unit far away of 1m in the noise pressure average: ≤ 250KW> 250KW ≤ 102db (A) ≤ 108db (A) Noise standards: Sleep <45db neighborhood ambient noise daily should not exceed 50 decibels through the night must be under 45 ( 40 ) dB Work <65db person with average skills at 40 decibels sound can be maintained normal reaction and attention , but at 50 decibels and up from the work place , quite a while is going to be the loss of hearing, emotional irritability , and in many cases appears neurasthenia phenomenon . Music 80db noise above 80 decibels children are in an atmosphere , contributing to approximately 50% in the deaf-mute , background level only 80 db or less, so that you can maintain long-term work for 40 years without deafness ; at 100 dB, only 60% of individuals tend not to would deafness. When you have long lived in a environment above 80 decibels can cause emotional irritability , tinnitus . Noise is harmful towards human nervous system which enable it to cause cardiovascular diseases, in strong noise environment, eating , gastrointestinal contractions occur capillaries , digestive fluid secretion and gastrointestinal motility will likely be weakened, in order that normal circulation have been damaged. Intense noise may also cause abnormal pregnancy , children's slowness .
Therefore, their daily lives to reduce noise sources and propagation . 85 db This might result in hook the loss of hearing ; -90 Db 85 db noise might cause deafness few individuals ; 90-100 decibels may cause a great amount of noise-induced tinnitus ; 100 db or more, it's going to create a significant amount of noise-induced tinnitus, these include chronic noise-induced deafness. 21 , fuel consumption rates. Rated power at 120 units 22 , diesel generators consumption rates. Unit rated power > 40KW, it consumption rate ≤ 3.0G/KW.H 23 , running test at standard conditions Unit with the required operating conditions (GB2820 in 4.2 ) , the device could be calibrated condition normal continuous operation 12h ( including 10% overload run 1h), and heavy duty diesel generators sets should not be any leakage and leakage phenomenon. Fourth, the most popular collection of diesel generator sets Some heavy duty diesel generators set to your long period of time or frequently carried out continuously , as a common electrical load power supply, commonly known style of turbine generators . Used generator sets works extremely well as common unit and the standby unit . From large grid towns , islands, forestry , mining, oil along with regions or perhaps the mining industry , in order to supply local residents plant health and wellbeing electricity , it is advisable to install diesel generators, such generators usually ought to be uninterrupted . Defense engineering , communications hub , radio , microwave relay stations along with other important facilities , will be forwarded to standby diesel generator sets. Such facilities can usually mains electricity supply grid . However, because of earthquakes, typhoons, and also other disasters, war or human factors, in order that the destruction in the city grid power failure as soon as the standby unit has become set should start quickly and stick long-term continuous manner, to make certain these important projects for electricity continuous power for the load , this group also participate in the standby generators used generator type. Used generator sets continued to work extended stays , the burden curve larger unit capacity , number of units, type selection and control units and emergency units of ways . Two popular heavy duty diesel generators to discover the quantity of units Used heavy duty diesel generators set variety of units usually 2 units or more, in order to ensure continuity of supply in order to adjust to adjustments to electricity load curve . Multi- unit Volume of units before they might change depending on the electrical load to look for the conduct of investment in generating units Amount of units , the engine is frequently running under load throughout the market as a way to reduce fuel consumption and minimize electricity costs. The very best economic engine running at rated power between 75 % -90% . To guarantee continuity of supply , popular units themselves must look into setting the standby unit , when the unit failure or downtime maintenance inspection, the generator set is imperative that you be able to fulfill the continuous method of getting uninterrupted electricity load .
