发电类必威体育官网betway

     

配发电机组的D系列必威体育官网betway功率范围为20.6-44KW,为了满足发电机组50Hz和60Hz两种不同频率的需要,其转速分为1500r/min和1800r/min。同时495BD发电机组是连续三次荣获国家金质奖的495B型必威体育官网betway的变形产品。

  

必威体育官网betway进气方式有自然进气和增压两种,其输出端的连接尺寸符合IMB34标准或SAEB标砖。该机可增设温度、压力和转速传感器,还可根据用户要求进行特殊设计。

  

The power range of D series diesel engine matched with generatorset is from 20.6-44KW. In order to meet the neeeds for twodiffcrcnt frequencies 50Hz and 60Hz of generator set, the rated speed can be either at 1500r/min or and 1800r/min. 495BD generator set is a modified version of Model 495B Diesel engine which has been awarded continuously the National Golden Medal prize thrice.

  

There are two kinds of air feeding of diesel engine, natural aspirated and turbocharger type, and the connecting dimensions of output end are in compliance with IMB34 international standard or SAE standard. This engine can be equippped additionally with emperature pressure, speed sensors and special design can be performed according to the customer's requirement.
