抽油泵衬套垂直度简易测量仪

Simple measuring meter for verticality of oil well pump liners

为解决抽油泵衬套垂直度测量较困难的问题，根据抽油泵衬套的特点，设计了抽油泵衬套垂直度简易测量仪。测量仪由空心立柱、调节顶丝、调节锥杆、千分表和精密平板等组成。介绍了简易测量仪的结构及操作原理，并对测量精度进行了分析。指出在实际生产中应根据需要选择合适精度的精密平板、空心立柱和千分表来装配，以满足抽油泵衬套测量精度要求。

To solve the problems with the measuring of the verticality of oil well pump liners, a simple measuring meter is designed. The measuring meter consists of hollow column, regulating screw, regulating rod, clock gauge and precise flat plate. The working principle of the meter is introduced, and measuring accuracy of the meter is analyzed. It is indicated that the precise flat Plate, hollow column and clock gauge should be selected properly to satisfy actual requirements for measuring accuracy of oil well pump liners.
