抽水工作在水文地质勘探中的工作量很大,亦很重要。常用的抽水设备都较复杂且订货困难,供应不上,如空气压缩机或深井抽水机等。较简单的普通离心抽水机则限于一定的水位条件而不能普遍应用。前二者设备都较复杂,每使用一次都需化很多的安装与拆卸时间、在野外如遇到损坏时,修理亦很困难,更主要的是每套抽水工具包括附件在一起,重量都很 It is also important that pumping work is heavy and heavy workload in hydrogeological exploration. Common pumping equipment are more complex and ordering difficulties, not on the supply, such as air compressors or deep well pumps. Simpler ordinary centrifugal pump is limited to a certain level of water conditions and can not be widely used. The first two devices are more complex, each use requires a lot of time to install and disassemble, in the field in case of damage, the repair is also very difficult, more important is that each set of pumping tools, including accessories together, the weight is very
