Mind XTZH-III V4.1system of efficiency comprehensive test、analysis and diagnosis of mechanical oil-production system take a notebook computer as a master machine, it is equipped with a software of comprehensive efficiency analysis of mechanical production system and expert diagnosis system, a software for pumping unit torque analysis and balance analysis and diagnosis ,a software for pump condition diagnosis, a software for testing pump leakage, sensor of load-shift dynamometer card and data collection circuit, pulley rotation speed sensor and its data collecting circuit, Through circuits of a power collector, Hall rotation speed collector, and a collector dynamometer card and by using stroke as a circle, the testing system can be used for accurately measuring the key parameters of active power, reactive power, power factors, surface dynamometer card, depth of dynamic fluid level, oil pressure and casing pressure, dynamometer card of polishing rod, and the pulley speed in the reduction box.The system can be used to test and calculate the operation parameters, and deliver various operation curves and statement based on actual needs, and diagnosis automatically the tested result, thus the efficiencies of subsystem and the whole system of the mechanical production system are completely and accurately analyzed and evaluated for searching a practical solution for improving the operation efficiency in the oilfields for a practical guidance of actual production. The testing and calculation of the system are conducted by windows interface. It is easy operation with rich and accurate contents, and it is the most perfect and advanced software of guiding the efficiency testing of mechanical production in the oilfields of china. Open pattern is used in the software of the system, it also can be custom-made according to the actual oilfield needs.
