發電類柴油機

     

配發電機組的D系列柴油機功率范圍為20.6-44KW,為了滿足發電機組50Hz和60Hz兩種不同頻率的需要,其轉速分為1500r/min和1800r/min。同時495BD發電機組是連續三次榮獲國家金質獎的495B型柴油機的變形產品。

  

柴油機進氣方式有自然進氣和增壓兩種,其輸出端的連接尺寸符合IMB34標準或SAEB標磚。該機可增設溫度、壓力和轉速傳感器,還可根據用戶要求進行特殊設計。

  

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.
