As the molecular pump pumping speed for water vapor is only with the diameter cryopump pumping speed of the quarter, so molecular pump exhaust pump longer time than low temperature.

由于分子泵对水蒸气的抽速仅为同口径低温泵抽速的四分之一，所以分子泵的排气时间比低温泵长。

Schwing poppet valve hydraulic piston pump be used in many municipal and industrial projects world wide.Today,Schwing was recognized as technology leader of"Dewatered sludge Pumping System".Schwing pump can pumping the sludge even with 56%solid content,for other inorganic material even with 80%solid content.Schwing units have operated continuously for years with 99%availablity.For sludge storage,Available in circular or rectangular design,the sliding frame/push floor technologies provide low cost methods to store large volumes of material w你好le awaiting final disposal.Schwing sliding frame system in the bottom of the silo,disc harge the sludge with the screw into sludge truck or Schwing pump.The typical installation is silo with pump installed beside the dewatering mac你好ne.A Schwing silo can be integrated into the process stream to equalize surges in solids production and subsequently meter cake to final disposal.Large diameter storage silos are useful for truck loading,and finally,both sliding frame and push floor designs are effective as receiving stations used to accept sludge hauled in from other facilities.Ultimately,the storage volume of the silos and bunkers dictate the plant''s flexibility in disposing of the solids.
