Zhuji Oil Mill majority of revolutionary workers in the “Daqing Daqing” mass movement, with “China should make a greater contribution to mankind,” the pride of desire, self-reliance and arduous struggle to overcome all difficulties, successful trial of SZ-2 water Ring vacuum pump, is now in production, is our province to create SZ-2-type water ring vacuum pump a good start.
