Problems solved by technology

[0004] However, during the spectrum preparation process, air bubbles often appear in the oil sample and cleaning agent in thistle tube, and the bubbles will greatly damage the arrangement of abrasive particles on the spectrum sheet. This is a common problem in thistle tube ferrography instruments

Embodiment 1

[0034] Such as Figure 1-4 As shown, the thistle tube of embodiment 1 and the method for eliminating air bubbles in the thistle tube of thistle tube ferrgraph include thistle-shaped glass tube 2, which includes a funnel 22 and a conduit 21 which are arranged in communication, and the funnel 22 is movable A suspension is provided, the density of the suspension is not greater than the density of the oil sample and the cleaning agent, and the suspension is sealed with the inlet of the conduit 21 .

[0035] The suspension part is a hollow ball 1 , and the diameter of the hollow ball 1 is larger than the inner diameter of the conduit 21 .

[0036] The hollow ball 1 is a polypropylene hollow ball.

[0037] A method for eliminating air bubbles in the thistle tube of thistle tube type ferrography instrument, comprising:

[0038] Step 1. When the oil sample flows through the funnel 22, the hollow ball 1 changes with the liquid level of the oil sample in the funnel 22;

[0039] Step ...

Embodiment 2

[0045] Such as Figure 5 As shown, Embodiment 2 is based on Embodiment 1, the difference is that: the outer wall of the hollow ball 1 is provided with several grooves 11 .

[0046] The difference between embodiment 2 and embodiment 1 is: the groove 11 can produce certain resistance to the flow of oil or cleaning agent, when the hollow ball 1 rolls, the oil or cleaning agent cannot be taken out by the hollow ball 1, thus The generation of oil or cleaning agent air bubbles is reduced.

Embodiment 3

[0048] Such as Figure 6 As shown, Embodiment 3 is based on Embodiment 1, the difference lies in that the center of gravity of the hollow ball 1 and the center of the ball are misplaced.

[0049] There is a distance between the center of the circle where the inner wall of the hollow ball 1 is located and the center where the outer wall is located.

[0050]The difference between Embodiment 3 and Embodiment 1 is that the center of gravity of the hollow ball 1 is deviated from its center. When the hollow ball 1 is suspended in oil or cleaning agent, its center of gravity is always kept below the center. At this time, the oil Or when the cleaning agent falls, the hollow ball 1 shakes in a certain small range without rolling, thereby avoiding the generation of air bubbles in the oil or cleaning agent.

Abstract

The invention discloses a thistle tube and a method for eliminating bubbles in the thistle tube of a thistle tube type ferrograph, the thistle tube comprises a thistle type glass tube, the thistle type glass tube comprises a funnel and a conduit which are communicated with each other, a suspension part is movably arranged in the funnel, the density of the suspension part is not greater than the density of an oil sample and a cleaning agent, and the suspension part is hermetically matched with an inlet of the conduit. The thistle pipe and the method for eliminating the bubbles in the thistle pipe type ferrograph are reasonable, the suspension part changes along with the liquid level of the oil sample, when the oil sample in the funnel flows out, the suspension part blocks the inlet of the guide pipe, and the flow speed of oil in the guide pipe is reduced, so that the bubbles in the oil can be effectively reduced.

Description

technical field [0001] The invention relates to a thistle-shaped glass tube, in particular to a thistle tube and a method for eliminating air bubbles in the thistle tube of a thistle-tube ferrgraph. Background technique [0002] Oil analysis technology is an important branch of modern fault diagnosis technology, among which ferrography analysis technology is the most widely used and mature. At present, there are two types of ferrography widely used at home and abroad: analytical ferrography and direct reading ferrography. [0003] The analysis method of the analytical ferrography instrument is to use a high gradient magnetic field to separate the abrasive particles in the oil, deposit them on the ferrographic substrate in a regular arrangement, and analyze the number, size distribution, composition, type, etc. of the abrasive particles with the help of a microscope. , and then determine the condition of equipment wear. Abrasive deposition ferrograms produced by analytical ...
