Problems solved by technology

However, the flow speeds of different metal particles in the oil are different, and the number of turns 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 pump consumes a lot of energy for continuous oil delivery, which increases the evaluation cost

Abstract

The invention discloses a device for evaluating the performance of an on-line flowing oil metal particle monitoring sensor. The device is characterized by comprising a base plate, a supporting component, a sensor mounting table, a transmission belt and a transmission belt driving device, wherein the supporting component and the sensor mounting table are fixedly arranged on the base plate; the transmission belt driving device is arranged on the supporting component; the on-line monitoring sensor to be evaluated is arranged on the sensor mounting table; the transmission belt runs through the inner cavity of the on-line monitoring sensor to be evaluated; two ends of the transmission belt are connected with each other to form a closed loop structure; a fixed number of metal particles are fixedly arranged on the transmission belt. The device has the advantages that the metal particles are fixedly and cyclically transmitted through the transmission belt to the inner cavity of the on-line monitoring sensor to be evaluated, so that the performances such as the detection rate of the flowing-through metal particles and the detectable minimum particle size can be evaluated, and an obtained evaluation result is precise and reliable; meanwhile, the device is only powered by external electric energy or mechanical energy; therefore, the energy is saved, and the evaluation cost is reduced.

Description

technical field [0001] The invention relates to an evaluation device, in particular to an evaluation device 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 device generally consists of a fuel pump and a fuel pipe with an online monitoring sensor to form a circulation loop. A fixed number of metal particles are loaded into the fuel pump in advance, and the oil in the fuel pump continues to circulate through the fuel pipe to drive the metal particles in the oil. Circular movement, and finally evaluate the performance of the online monitoring sensor on the detection rate of the metal particles flowing through and the minimum particle size that can be detected. However, ...
