Description

Technical Field

[0001] The present invention relates to a thistle-shaped glass tube, and in particular to a thistle tube and a method for eliminating air bubbles in the thistle tube of a thistle-type ferrograph. Background Art

[0002] The oil analysis technology is an important branch of modern fault diagnosis technology, and among them, the most widely used and mature one is the ferrography analysis technology. At present, there are two types of ferrographs widely used at home and abroad: the analytical ferrograph and the direct-reading ferrograph.

[0003] The analysis method of the analytical ferrograph is to separate the abrasive particles in the oil by using a high-gradient magnetic field, arrange and deposit them on the ferrograph substrate according to rules, and analyze the number, size distribution, composition, type, etc. of the abrasive particles with the help of a microscope, so as to determine the wear condition of the equipment. The abrasive particle deposition ferrograph made by the analytical ferrograph contains rich information, and the wear condition of the equipment can be deeply studied by means of microscopic observation and other technologies.

[0004] However, during the spectrum preparation process, air bubbles often appear in the oil sample and cleaning agent in the thistle tube. The air bubbles cause great harm to the arrangement of the abrasive particles on the spectrum sheet, which is a common problem in thistle-type ferrographs.

[0005] Therefore, it is necessary to improve the thistle tube in the prior art. Summary of the Invention

[0006] The purpose of the present invention is to overcome the defects existing in the prior art, and provide a thistle tube and a method for eliminating air bubbles in the thistle tube of a thistle-type ferrograph, which can effectively reduce the generation of oil bubbles.

[0007] To achieve the above technical effects, the technical solution of the present invention is: a thistle tube and a method for eliminating air bubbles in the thistle tube of a thistle-type ferrograph, including a thistle-shaped glass tube, the thistle-shaped glass tube includes a funnel and a conduit which are communicated, a suspension member is movably arranged in the funnel, the density of the suspension member is not greater than the density of the oil sample and the cleaning agent, and the suspension member is in sealing cooperation with the inlet of the conduit. Through such a design, when the oil sample in the funnel runs out, the suspension member blocks the conduit inlet, the flow rate of the oil sample in the conduit decreases, and the oil sample falls gently, so that the generation of air bubbles in the oil can be reduced.

[0008] The suspension member is a hollow ball, and the diameter of the hollow ball is greater than the inner diameter of the conduit. Through such a design, the hollow ball can serve the purpose of blocking the conduit inlet.

[0009] The hollow ball is a polypropylene hollow ball. Through such a design, polypropylene has chemical resistance and good wear resistance, which can avoid the influence of corrosion and wear of the hollow ball on the test results.

[0010] The center of gravity of the hollow sphere is misaligned with its center of the sphere. Through such a design, the hollow sphere is eccentrically arranged. When it floats in the oil or cleaning agent, its center of gravity always remains below the center, and it sways within a certain small range, avoiding the tumbling of the hollow sphere and generating bubbles in the oil or cleaning agent.

[0011] There is a distance between the center of the inner wall of the hollow sphere and the center of the outer wall of the hollow sphere. Through such a design, the wall thickness of the hollow sphere is unequal, achieving the purpose of making the hollow sphere eccentric.

[0012] A number of grooves are provided on the outer wall of the hollow sphere. Through such a design, the grooves can generate a certain resistance to the flow of the oil or cleaning agent. When the hollow sphere tumbles, the oil or cleaning agent cannot be carried out by the hollow sphere, reducing the generation of bubbles in the oil or cleaning agent.

[0013] The suspension member is a gyro-shaped hollow cone, and the tip of the hollow cone is arranged downward in the floating state. Through such a design, the hollow cone can serve the purpose of blocking the inlet of the conduit.

[0014] The inlet section of the conduit is adapted to the outer wall of the hollow cone. Through such a design, the contact area between the hollow cone and the conduit can be increased, achieving a better sealing effect.

[0015] A method for eliminating bubbles in the thistle tube of a thistle tube type ferrograph, comprising:

[0016] Step 1: When the oil sample flows through the funnel, the suspension member changes with the liquid level of the oil sample in the funnel;

[0017] Step 2: When the oil sample in the funnel runs out, the suspension member fits with the inlet of the conduit, blocking the inlet of the conduit, and the flow rate of the oil sample in the conduit decreases and it falls gently;

[0018] Step 3: After the oil sample in the conduit runs out, introduce a cleaning agent into the funnel, and the suspension member changes with the liquid level of the cleaning agent in the funnel;

[0019] Step 4: When the cleaning agent in the funnel runs out, the suspension member fits with the inlet of the conduit, blocking the inlet of the conduit, and the flow rate of the cleaning agent in the conduit decreases and it falls gently.

[0020] The advantages and beneficial effects of the present invention are as follows: The thistle tube of the present invention and the method for eliminating bubbles in the thistle tube of the thistle tube type ferrograph have a reasonable structure. The density of the suspension member is less than the density of the oil sample and the cleaning agent. When the oil sample flows through the funnel, the suspension member changes with the liquid level of the oil sample. When the oil sample in the funnel runs out, the suspension member blocks the inlet of the conduit, and the flow rate of the oil sample in the conduit decreases, and the oil sample falls gently, effectively reducing the generation of bubbles in the oil and the cleaning agent.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0033] Example 1

[0034] As Figure 1-4 shown, the thistle tube of Example 1 and the method for eliminating air bubbles in the thistle tube of the thistle tube type ferrograph include a thistle-shaped glass tube 2. The thistle-shaped glass tube 2 includes a funnel 22 and a conduit 21 that are communicatively arranged. A floating member is movably arranged in the funnel 22. The density of the floating member is not greater than the density of the oil sample and the cleaning agent. The floating member is sealingly fitted with the inlet of the conduit 21.

[0035] The floating member is a hollow ball 1, and the diameter of the hollow ball 1 is greater 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 the thistle tube type ferrograph includes:

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

[0039] Step 2: When the oil sample in the funnel 22 runs out, the hollow ball 1 fits with the inlet of the conduit 21 to block the inlet of the conduit 21, and the flow rate of the oil sample in the conduit 21 decreases and it falls gently;

[0040] Step 3: After the oil sample in the conduit 21 runs out, a cleaning agent is introduced into the funnel 22, and the hollow ball 1 moves with the liquid level of the cleaning agent in the funnel 22;

[0041] Step 4: When the cleaning agent in the funnel 22 runs out, the hollow ball 1 fits with the inlet of the conduit 21 to block the inlet of the conduit 21, and the flow rate of the cleaning agent in the conduit 21 decreases and it falls gently.

[0042] Usage method of Example 1: The thistle-shaped glass tube 2 is designed into two parts, namely a funnel 22 and a conduit 21 that are communicatively arranged, and a hollow ball 1 is placed in the funnel 22. When the oil sample flows through the funnel 22, the hollow ball 1 moves with the liquid level of the oil sample. When the oil sample in the funnel 22 runs out, the hollow ball 1 blocks the inlet of the conduit 21, and the flow rate of the oil liquid in the conduit 21 decreases and it falls gently, which can effectively reduce the generation of oil liquid bubbles;

[0043] When the oil sample in the conduit 21 is exhausted, a cleaning agent is introduced into the funnel 22. The hollow ball 1 moves with the change in the liquid level of the cleaning agent in the funnel 22. When the cleaning agent in the funnel 22 is exhausted, the hollow ball 1 fits against the inlet of the conduit 21, sealing the inlet of the conduit 21. The flow rate of the cleaning agent in the conduit 21 decreases and it falls gently, effectively reducing the generation of bubbles in the cleaning agent.

[0044] Embodiment 2

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

[0046] The difference in use between Embodiment 2 and Embodiment 1 is that: the grooves 11 can generate a certain resistance to the flow of the oil or the cleaning agent. When the hollow ball 1 tumbles, the oil or the cleaning agent cannot be carried out by the hollow ball 1, thereby reducing the generation of bubbles in the oil or the cleaning agent.

[0047] Embodiment 3

[0048] As Figure 6 shown, Embodiment 3 is based on Embodiment 1, with the difference that: the center of gravity of the hollow ball 1 is misaligned with its center of the sphere.

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

[0050] The difference in use between Embodiment 3 and Embodiment 1 is that: the center of gravity of the hollow ball 1 is offset from its center. When the hollow ball 1 is suspended in the oil or the cleaning agent, its center of gravity always remains below the center. At this time, when the oil or the cleaning agent falls, the hollow ball 1 sways within a certain small range and does not tumble, thereby avoiding the generation of bubbles in the oil or the cleaning agent.

[0051] Embodiment 4

[0052] As Figure 7-9 shown, Embodiment 4 is based on Embodiment 1, with the difference that: the suspension member is a gyro-shaped hollow cone 3, and the tip of the hollow cone 3 is downward in the suspended state.

[0053] The inlet section of the conduit 21 is adapted to the outer wall of the hollow cone 3.

[0054] The difference in use between Embodiment 4 and Embodiment 1 is that: as the oil sample or the cleaning agent in the funnel 22 is exhausted, the tip of the hollow cone 3 inserts into the conduit 21, and the outer wall of the hollow cone 3 fits against the inlet section of the conduit 21, increasing the contact area between the hollow cone 3 and the conduit 21, achieving a better sealing effect. Thus, the inlet of the conduit 21 is blocked, the flow rate of the oil in the conduit 21 decreases and it falls gently, effectively reducing the generation of oil bubbles.

[0055] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
