砼真空脱水的关键设备主要包括两部分:产生负压的真空泵和与砼接触从中脱出水的吸水装置。国内普遍使用的 HZG—60型砼专用真空泵,其水环泵和集水箱安装在小车上。利用从砼中脱出的水作为工作介质产生真空,同时排出水和气的混合物。水箱分为两部
The key equipment for vacuum dehydration consists of two main parts: a vacuum pump that generates negative pressure and a water-absorbing device that removes water from contact with the crucible. The HZG-60 type vacuum pump is commonly used in China and its water ring pump and water collection tank are installed on the trolley. A vacuum is generated using the water that has come out of the crucible as a working medium while discharging a mixture of water and gas. The water tank is divided into two parts
