Test device for simulating lubricating oil quality faults on line and using method thereof

Abstract

The invention discloses a test device for simulating lubricating oil quality faults on line and a using method thereof. The test device comprises an oil tank, and the oil tank is provided with an oiladding port and an oil discharging port. The test device is characterized in that a stirring blade is arranged in the oil tank, the stirring blade is connected with a driving mechanism, a temperaturesensor, a lubricating oil viscosity sensor, a water content sensor and an electric heating pipe are further arranged in the oil tank, the two ends of the oil tank are communicated through a pipeline,and a first adjustable electric valve, a granularity detection unit, an oil pump, a second adjustable electric valve and a flow meter are connected to the pipeline in series. The test device has the following beneficial effects that the aging and deterioration faults of oil due to long-term work or water mixing can be identified; the failure of the oil tank due to respiration or pipeline sealing can be identified; sudden invasion of metal particles and external pollution particles caused by abrasion of a friction pair can be identified; the system can normally operate for a long time under thecondition of lubricating oil pollution; and complex faults of the lubricating oil can be detected.

Description

technical field [0001] The invention relates to a test device, in particular to a test device for online simulation of lubricating oil quality faults and a method for using the test device. Background technique [0002] Lubricating oil is widely used in various mechanical equipment to play the role of lubrication, cooling, cleaning, sealing, and rust prevention. Because some lubricating oils work under very harsh conditions, such as high temperature, high pressure, poor sealing or no sealing, mechanical wear and tear of parts, etc. This will lead to deterioration of lubricating oil, water emulsification, metal particles, oxides, sludge precipitation and other impurities, pollution and deterioration will cause changes in the physical and chemical properties of the lubricating oil, and the lubricating effect will deteriorate. In practical applications, it is very necessary to monitor changes in viscosity, water content, metal particle size, and non-metal particle size of lubr...

AI Technical Summary

Problems solved by technology

[0004] 1. Online real-time monitoring, capable of real-time monitoring of various parameters of lubricating oil, simple structure, fast response, timely feedback on problems with lubricating oil, easy to operate, but in some environments, additional pipelines for testing need to be installed

[0005] 2. Off-line analysis and measurement, easy to maintain, no need to install additional pipelines in the lubrication system, but it needs to be sampled first and then analyzed, the operation is complicated, and the return of the measurement results has a time lag, so it is not suitable for real-time monitoring

[0007] 1. Metal particles, water, non-metal particles and other impurities are directly put into the oil tank, which cannot be fully mixed into the oil, and cannot truly reflect the pollution degree of the lubricating oil

[0008] 2. Impurities are directly mixed into the real unit, which is easy to cause permanent damage to the unit components

[0009] 3. There are fewer types of simulated faults, the sensor detection method is single, and it is not possible to simulate multiple faults at the same time
