The utility model relates to a novel material delivery system esterifies, including esterification reaction cauldron, condensation polymerization cauldron and mass flow meter, on mass flow meter installed the pipeline between esterification reaction cauldron and condensation polymerization cauldron, its characterized in that had increased by 2 melt -conveying pumps, and 2 melt -conveying parallels connection of pumps are installed between esterification reaction cauldron and mass flow meter, carry through the asynchronous condensation polymerization 2 rotary speed control of the three -phase of melt -conveying pump. The bubble that the delivery pump mix with pulverize the material in the continuous operation output process in to the instantaneous feeding volume of control material is stable, and control is accurate, guarantees the product quality. 本实用新型种新型酯化物料输送系统，包括酯化反应釜、缩聚反应釜以及质量流量计，质量流量计安装在酯化反应釜与缩聚反应釜之间的管线上，其特征在于增加了2台熔体输送泵，2台熔体输送泵并联并安装在酯化反应釜与质量流量计之间，通过熔体输送泵的三相异步变频电动机转速控制输送。输送泵在连续运行输出过程中碾碎物料中夹杂的气泡，从而控制物料瞬时进
