Off-line oil granularity detecting system and detecting method

Abstract

The invention relates to an off-line oil granularity detecting system comprising an oil granularity detector (1) and an oil sample conveying system. The oil sample conveying system is composed of a lifting device (5), a conveyor belt motor (6), a conveyor belt A (7), a conveyor belt A (9), an oil sample inspection waiting bench (11), a conveyor belt B (12), a conveyor belt B (14), an oil sample bottle detection bench (16), an object level sensor A (17) and a mounting plate (19). While the high detection efficiency of the oil granularity is ensured, the detection efficiency is improved and the labor cost is lowered. The detecting system and detecting method are particularly suitable for occasions with the high detection precision requirements and large detection amount.

Description

technical field [0001] The invention relates to an oil particle size detection system, in particular to an off-line oil particle size detection system with high detection accuracy, high detection efficiency and low labor cost. Background technique [0002] Oil particle size is an objective measure of the granularity of petroleum products, reflecting the distribution, size and quantity of particles in the oil. This index is useful for grasping the operation status of mechanical equipment, detecting and predicting fault locations, and guiding the maintenance of mechanical equipment and maintenance are important. At present, the characterization of oil particle size is usually carried out by the particle counting analysis method of the shading particle counter, which is mainly divided into three types: off-line, portable and on-line. Among them, the off-line particle counter is to use a clean oil sample bottle to sample the liquid sample to be analyzed from the field, and then...

Problems solved by technology

The advantage of this method is that the data stability and measurement accuracy are high, but the disadvantage is that it has high requirements for the control of each link of the test, the test process is cumbersome, and the test efficiency is low; in order to achieve the purpose of on-site use, the portable particle counter is usually compared with the offline particle counter. The size and weight are smaller, which inevitably leads to the reduction of the measurement accuracy and repeatability of the counter itself; the online particle counter usually installs the counter on the oil circuit of the equipment, and the test is fast, which can realize the monitoring of the particle size of the system oil, but it is not enough The disadvantages are the difficulty of counter calibration and the low repeatability and accuracy of test results

Low detection efficiency

In addition, it is necessary to set up professional testers for testing, and if the test volume is large, it is necessary to shift shifts on the same post, resulting in high labor costs
