Product Information

I. Purposes: JZ series weight indicator is an instrument used to instruct and record changes in the hanging loads and bit pressure of the drilling rigs in oil and geological exploration drilling (workover). It helps the drillers to master the drilling (workover) parameters and determine the working state of the drilling tools. II. Features: 1. JZ series weight indicator has 14 categories and 23 specifications to be selected for different types of drilling (workover) rigs and it consists of a dead line fastener, a weight indicator, and a recorder. The dead line fastener can be either vertically or horizontally installed; 2. It is high in accuracy and reliable in performance; 3. Good in corrosion resistance and the anti-corrosion magnifying mechanism adapts to marine operating environment; 4. The double-system super dew can be used not only domestically but also to meet the requirements of foreign users; 5. Pipe joints are quick and self-sealing, and the pipeline connection is fast, convenient, and reliable; 6. The ink recording curve of the recorder facilitates the establishment of drilling files.
