Device for full-automatically measuring kinematic viscosity and viscosity index of electrical equipment oil and measuring method

Abstract

The invention relates to a device for full-automatically measuring the kinematic viscosity and the viscosity index of electrical equipment oil and a measuring method. A current kinematic viscosity measuring product commonly adopts water bathing to control temperature, meanwhile, a viscometer is a fixed coefficient, and cannot meet the requirement for measuring in a larger range, the error is large, and most of products cannot measure the viscosity index of an oil product. The device adopts the Lambert-Beer's law to judge the moment of an oil sample passing the marked line through the transmittance of the viscometers filled with the oil product and empty viscometers after being washed, and by comparing the transmittance before measuring and in the measuring process, high precision and fullautomatic measuring of the kinematic viscosity and the viscosity index of the electrical equipment oil are achieved. Meanwhile, a metal constant temperature bathing is adopted to replace a traditionalwater bathing and oil bathing constant temperature pool, operation and maintenance is more convenient, and temperature control is more precise. Quantitative pipes and automatic propellers are arranged so as to achieve automatic sample feeding; a compressor is arranged to pressurize and boost to fill the oil sample, and generation of bubbles can be effectively reduced; and by designing a vacuum bottle, oil is drained, and by designing an anti-suck-back stopping plate, oil can be drained more thoroughly.
