Description

Automatic cleaning device for oil sample ferrographic analysis glass test tube
Technical Field
The invention relates to the field of oil analysis, in particular to an automatic cleaning device for an oil sample ferrography analysis glass test tube.
Background
The oil sample ferrography analysis technology is an oil sample analysis method which utilizes an iron spectrometer to separate and detect abrasive particles and debris from a lubricating oil (grease) sample so as to analyze and judge the wear type, the wear degree and the wear part of a mechanical kinematic pair. When carrying out ferrography, because the viscosity of the equipment oil of using is generally great, in order to improve efficiency and the quality of preparation tablet, need absorb tetrachloroethylene solvent and fluid according to certain dilution ratio and place glass test tube in and mix evenly. When the operating condition of mechanical equipment is analyzed by utilizing the ferrographic technology, the quantity of the collected oil samples is generally large, and the oil samples comprise oil samples at different positions and oil samples at the same position under different operating times. In order to avoid the influence of the mixing of the oil samples on the analysis result, a test tube is required to be used for one oil sample during spectrum preparation. Thus, after a batch of oil samples has been analyzed, the number of tubes used is large. In order to avoid the long-time deposition of residual oil on the inner wall of the test tube and prepare for the next experiment, the test tube needs to be cleaned in time.
Currently, there are two main methods for cleaning glass test tubes in the laboratory:
(1) and cleaning by using an ultrasonic cleaning machine. Because the viscosity of the oil used by the equipment is generally higher, the difficulty of cleaning the residual oil in the test tube by using ultrasonic waves is higher, and a cleaning agent is more consumed; in addition, the stripped oil can float in the cleaning tank and is easily adhered to the inner wall and the outer wall of the test tube again, so that the test tube is difficult to clean completely.
(2) And (4) manually cleaning. Adding a cleaning agent into the test tube to be cleaned, manually brushing the test tube by using a brush, and then washing the test tube by using clear water. The disadvantages are as follows: in the manual cleaning process, if the operation is not proper, the test tube is broken, so that the test tube is easy to damage experimenters, and polluted oil or cleaning agent is easy to cause infection; in addition, the experimenter needs to spend certain time cleaning the test tube, which wastes time and labor and has low cleaning efficiency.
