浅论设计灌注泵的几个问题

Considerations in the design of charging pumps

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。

The charging pump often operates on off-normal working conditions and is generally used for conveying fluid of high viscosity with silt. So in designing the charging pump,such parameters as the displacement, lift and rotating speed, as well as the design of its seals.should be properly selected according to its working conditions to ensure that it will operate stably and meet the suction requirement of the triplex pump.
