灌注泵属离心泵的范畴。与通用离心泵的不同之处是,灌注泵往往在偏离工况下工作,输送的介质粘度大,还含有泥砂。设计灌注泵时,必须针对其工作特点,合理地选择泵的排量Q、扬程H、转速n等性能参数,以及密封装置及其结构形式等,以保证灌注泵工作稳定,满足三缸泵的吸入要求。 Pouring pump belongs to the category of centrifugal pump. Unlike conventional centrifugal pumps, perfusion pumps tend to work in off-center conditions and have a high viscosity and contain silt. The design of the pump, must be based on its operating characteristics, a reasonable choice of the pump displacement Q, head H, speed n and other performance parameters, as well as the sealing device and its structure, etc., to ensure that the pump stable operation, to meet the three-cylinder pump Inhalation requirements.
