摘　　要：针对CMT监测井监测通道内径小引起的采样困难的问题,研究了一种新型的轻便机动惯性泵,并对轻便机动惯性泵的可靠性进行了分析,对电机转速、采样深度、通道内径和采样管规格对采样速度的影响进行了试验研究,为后续轻便机动惯性泵的改造奠定了基础,为小口径监测井采样提供了借鉴。Aiming at the difficulty in water sample collection caused by small diameter monitoring channel of CMT monitoring well, a new type of portable motorized inertial pump is developed and its reliability is analyzed. The tests and studies are made on the influence of motor speed, sampling depth, channel diameter and sampling tube specifications on sampling speed, which lays the foundation for retrofitting portable motorized inertial pump and provides reference for the sampling of small diameter monitoring wells.
