Problems solved by technology

However, the flow speed of different metal particles in the oil is different, and the number of circles that each metal particle flows through the online monitoring sensor during the whole evaluation process is inconsistent, and in the oil pipe, especially at the end joint of the oil pipe, due to the small cross-sectional area of ​​the pipe Or there are structures such as threads that hinder the movement of metal particles, and the metal particles may be stuck at the end joints in the oil pipe. Therefore, the final evaluation results of the online monitoring sensor performance are somewhat unreliable, arbitrary, and not accurate enough; In addition, the oil delivery pump needs to continuously deliver oil, which consumes a lot of energy and increases the evaluation cost

Abstract

The invention discloses a method for evaluating the performance of a sensor for monitoring metal particles in flowing oil liquid on line. The method is characterized by comprising the following steps: a supporting assembly and a sensor installing platform are installed on a base plate, a conveyor belt driving device is arranged on the supporting assembly, the on-line monitoring sensor to be evaluated is fixed on the sensor installing platform, metal particles with the consistent size are fixed on a conveyor belt, the conveyor belt is supported on the conveyor belt driving device and passes through the inner cavity of the on-line monitoring sensor to be evaluated, and the metal particle detection rate of the on-line monitoring sensor is evaluated; the conveyor belt is taken down, the original metal particles are removed, metal particles with different sizes are fixed on the conveyor belt, the conveyor belt is repeatedly installed and operates, finally, the metal particle with the smallest size, detected by the on-line monitoring sensor to be evaluated, is found out, and the performance of the on-line monitoring sensor is evaluated. The method has the advantages that an evaluation result is accurate and reliable, energy sources are saved, and the evaluation cost is reduced.

Description

technical field [0001] The invention relates to an evaluation method, in particular to an evaluation method for on-line monitoring sensor performance of metal particles in flowing oil. Background technique [0002] The on-line monitoring sensor for metal particles in flowing oil has the function of detecting the number of metal particles flowing through and the particle size of the metal particles. diameter performance evaluation. [0003] The existing evaluation method generally connects one end of two oil pipes to both ends of the on-line monitoring sensor, and connects the other end of the two oil pipes to the input port and output port of the oil pump respectively to form a circulating transport system. Oil structure, the oil pump is loaded with a fixed number of metal particles in advance, the oil in the oil pump passes through the oil pipe and continues to circulate, driving the metal particles in the oil to circulate, and finally evaluates the online monitoring senso...
