BRIDGE-TYPE CONCENTRIC DIRECT READING TESTING AND COMMISSIONING INSTRUMENT

摘要

A bridge-type concentric direct reading testing and commissioning instrument. Same comprises: a cable head (1) having the lower end thereof connected to a pressure sensor (3) via a circuit board (2); a support mechanism (4) comprising a support arm fixing base (4b) and a pair of support arms (4a); a deviated well downward sliding power mechanism (5) comprising a power motor (5a), a spring (5b), an impact hammer (5c), and a one-way clutch component (5d), where the spring (5b) is arranged between the power motor (5a) and the impact hammer (5c), the impact hammer (5c) is slidably connected to the power motor (5a) and is capable of rotating along with rotations of the power motor (5a), the lower end of the impact hammer (5c) is detachably connected to the one-way clutch component (5d), the one-way clutch component (5d) is connected to the support arms (4a) via a transmission component (5e) to control the opening and collapsing of the support arms (4a); a flowmeter (6) connected below the support mechanism (4); and, a regulating actuator mechanism (7) connected blow the flowmeter (6), where the regulating actuator mechanism (7) comprises a regulating motor (7a), a regulating connector (7b), and a regulating arm (7c), the regulating motor (7a) is connected to the regulating arm (7c) via the regulating connector (7b) and regulates injected water flow via rotations of the regulating arm (7c).
