Note : volume of the expansion trough is more than twice that of the increment due to expansion of oil in the entire heat exchanging system caused by working conditions . in this system the expansion grough is always at the highest top . volume of cold oil trough is approx . 1 . 3 times of the system ' s total oil uantity . for specific installation mode and dimensions please consult our tech dept 注：膨胀槽体积大于热交换系统内所有油量工作条件下膨胀所引起的体积增大量的二倍，本系统膨胀槽总是位子系统的最高处，冷油槽体积约为系统内总油量的1 . 3倍，具体安装形式及尺寸请洽本公司技术部。
