The utility model provides a connecting device for deep well casing, which includes: several cylindrical casing, which are arranged in deep well bore to prevent deep hole wall from falling; an inner nozzle with a limit protrusion in the middle is used for connecting cylindrical casing, the inner diameter of the cylindrical casing is equal to the outer diameter of the inner nozzle, and the outer diameter of the limit protrusion is the same as the outer diameter of the cylindrical casing, so that the inner connection is made by transparent tape layer; and the outer diameter of the limit protrusion is equal to the outer diameter of the cylindrical The connection between the tube and the cylindrical sleeve is stronger and plays a sealing role. Compared with the related technology, the deep well casing connector provided by the utility model enables the deep well pump body to be in deep wells, and the casing port will not deviate under certain external forces, so as to maintain good concentricity. It is proposed to replace the deep well pump smoothly after several years.

深井套管连接件
本技术涉及一种深井套管连接件,用于深井安装作业。
技术介绍
深井泵的最大特点是将电动机和泵制成一体,它是浸入地下水井中进行抽吸和输送水的一种泵,被广泛应用于农田排灌、工矿企业、城市给排水和污水处理等。深井泵在投入深井中的时候,会将井底的泥沙或是井道壁周围的泥沙激起,从而在将深井泵投入使用过程中,容易造成泥沙较多的附着在进水节上或进入进水节内,不利于深井泵的抽水作业,年度久了之后,深井泵体无法拔出来,现有的技术采取在深井泵外设置一套管来解决,现有套管包括外接接头和大小头套管,存在接口凸出、胶抱接不平整,容易脱节,连接端口与套管大小不一致,在下管作业中出现深井孔井壁“掉块”,“掉块”卡住套管不仅无法下到井底,而且造成套管提出困难;现有套管与套管的端口连接达不到很好的同心度,深井泵置于套管中在深井工作时,套管端口受一定的外力作用下产生偏移,不能保持良好的同心度,深井泵体更换时提出不顺畅等问题。因此,有必要提供一种新的深井套管连接件解决以上技术问题。
技术实现思路
本技术提供一种深井套管连接件,通过凸台内接的连接件使深井泵体在深井中,套管端口受一定的外力作用下不会偏移,能保持良好的同心度,若干年后更换深井泵时提出顺畅。本技术的目的在于提供一种深井套管连接件,包括:若干圆筒状套管,套管设置在深井孔内,防止深井孔壁掉块;中间带限位凸台的内接管,用于圆筒状套管的连接,所述圆筒状套管的内径等于内接管的外径,限位凸台的外径与圆筒状套管外径相同;透明胶带层,使内接管与圆筒状套管的连接更为牢固,并起到密封作用。优选的,所述圆筒状套管的壁厚为3.0-3.2mm。与相关技术 ...
