Description

Technical Field

[0001] This application relates to the fields of material friction, wear and corrosion, and particularly to a tribo-wear and electrochemistry combined testing machine with a controllable environment. Background Art

[0002] With the development of society and technology, the application fields of mechanical equipment have been continuously expanding. Compared with the general environment, the friction, wear and corrosion properties of materials usually show different laws under different temperature, pressure, medium and atmosphere environments, which affect the performance of mechanical equipment. Therefore, experimental studies on the friction, wear and corrosion properties of materials under different environments are required. However, the commonly used tribo-wear testing machines at present can usually only carry out tribo-wear experiments under normal temperature, normal pressure and atmospheric environment, cannot meet the requirements of pressure, temperature, medium and atmosphere environment, and also cannot carry out combined friction and electrochemistry tests.

[0003] Individual testing machines have certain control capabilities for pressure and medium environment, but cannot control temperature, atmosphere, etc., and also cannot carry out electrochemistry tests under this environment. For example, the US patent application with the application number US15838326 and the publication number US20180202912A1 mentions a tribo-wear testing machine with an environment control module, which has the ability to carry out tribo-wear tests under certain temperature, certain humidity atmosphere, vacuum, gas and liquid environments, but cannot control temperature and pressure environments and cannot carry out electrochemistry tests. The Chinese patent application with the application number CN201910198034.9 and the publication number CN109883870A proposes a tribo-wear testing machine under seawater environment, which can carry out tribo-wear experiments under pressure and medium environments, but cannot control temperature and atmosphere and cannot carry out electrochemistry tests.

[0004] Reference 1 proposes a tribo-wear testing machine for simulating seawater environment, which can simulate pressure and medium environments, but cannot control temperature and cannot carry out electrochemistry tests.

[0005] Reference 2 proposes a tribo-wear testing machine for simulating seawater environment, which also cannot control temperature and atmosphere and cannot carry out electrochemistry tests.

[0006] Reference 3 proposes a tribo-wear testing machine for simulating seawater environment for seawater pumps, which can simulate pressure and medium environments, but the types and forms of friction pairs are limited, cannot control temperature and atmosphere, and also cannot carry out electrochemistry tests.

[0007] Reference 4 proposes a tribo-wear testing machine for simulating seawater environment, which can simulate pressure and medium environments, but cannot control temperature and has problems of leakage in mechanical transmission.

DETAILED DESCRIPTION

[0044] The exemplary embodiments of the present application will be described below with reference to the drawings. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not used to exhaust all feasible ways of the present application, nor to limit the scope of the present application.

[0045] This application provides a combined friction and wear and electrochemical testing machine with a controllable environment for the combined friction and wear and electrochemical testing of the first specimen 11 and the second specimen 12.

[0046] As Figure 1 、 2As shown, the friction and wear testing machine may include a pressure system, a friction system, a drive system, a control system, and an electrochemical testing system.

[0047] Pressure system

[0048] The pressure system may include a pressure vessel, a pressurizing device, and a pressure measuring device.

[0049] The pressure vessel includes a cavity 7 and an end cap 4. The cavity 7 has a cylindrical cavity, which serves as the test space of the combined friction and wear and electrochemical testing machine in a controllable environment. The end cap 4 abuts against the cavity 7, and the abutting position may be conical to play a sealing role. The cavity 7 and the end cap 4 may be connected by bolts (not shown in the figure). For example, after the end cap 4 abuts against the cavity 7, a stud can be used to pass through the end cap 4 in the thickness direction of the end cap 4 and be screwed into the cavity 7. One end of the stud exposed outside the end cap 4 can be tightened with a nut to achieve the seal between the end cap 4 and the cavity 7.

[0050] The pressurizing device may include a multi-pass tube 5, an intake valve 6, and a vent valve 32. As Figure 1 、 2 shown, an external pressure source 8 can be connected to the multi-pass tube 5, and the multi-pass tube 5 is connected to the intake valve 6. The intake valve 6 and the vent valve 32 can be arranged on the circumferential surface of the end cap 4. The intake valve 6 and the vent valve 32 can be connected to the cavity 7 through pipelines to realize the intake and vent of the cavity 7. The pressure source 8 can be a source for multiple gases communicating with the multi-pass tube 5. Through the pressure source 8 and the multi-pass tube 5, single or mixed atmosphere control for friction and wear tests under a pressure environment can be achieved. It can be understood that the pressure source 8 can be part of the combined friction and wear and electrochemical testing machine in this controllable environment, or an accessory device used in cooperation with the combined friction and wear and electrochemical testing machine in the controllable environment.

[0051] The pressure measuring device may include a pressure gauge 20, a burst valve 21, and a pressure transmitter 22. The pressure measuring device is connected to the cavity 7 through a pipeline passing through the end cap 4 to realize the measurement of the pressure environment inside the cavity 7. The pressure value inside the cavity 7 is displayed through the pressure gauge 20, the emergency pressure relief inside the cavity 7 is realized through the burst valve 21, and the pressure data can be transmitted into the console 1 (introduced later) in real time through the pressure transmitter 22.

[0052] It can be understood that the pipelines mentioned in this application should be interpreted in the broadest sense. For example, the pipelines in the sense of this application not only include individual pipe bodies, but also include grooves or channels formed inside or between components or members.

[0053] Friction system

[0054] The friction system may include a fixing device 13 and a loading device 10.

[0055] The first specimen 11 can be, for example, in the shape of a pin, and the second specimen 12 can be, for example, in the shape of a disc, to implement a pin-on-disc friction and wear test. The fixing device 13 can be fixed on the inner surface of the cavity 7 to provide a fixing space for the second specimen 12.

[0056] The loading device 10 can be disc-shaped and fixed on the main shaft 9. The lower end surface of the loading device 10 can be fixedly connected to the first specimen 11. By the axial movement or circumferential rotation of the main shaft 9, the loading device 10 drives the first specimen 11 to press against the second specimen 12 or move on the second specimen 12.

[0057] Drive system

[0058] The drive system can include a motor bracket 18, a motor 19, a transmission member, a magnetic drive device, a main shaft 9, and a lifting and rotating device.

The sealing body 24 is a cylindrical sealing body with a cylindrical cavity above the end cover 4, which serves to seal the gap between the main shaft 9 and the end cover 4. The main shaft 9 can have a stepped protrusion, and this stepped protrusion can abut against the end cover 4. By the axial downward movement of the end cover 4, a load is applied to the main shaft 9, so that the loading device 10 drives the first specimen 11 to press against the second specimen 12.

[0060] The outer ring 26 is installed outside the sealing body 24, the inner ring 27 is located inside the sealing body 24, and the inner ring 27 is installed at the upper end of the main shaft 9. Magnetic coupling can occur between the outer ring 26 and the inner ring 27. The motor 19 drives the outer ring 26 to rotate around the axis of the sealing body 24 through the belt 25. Due to the magnetic coupling between the outer ring 26 and the inner ring 27, the outer ring 26 drives the inner ring 27 to rotate around the axis of the main shaft 9, and the inner ring 27 drives the main shaft 9 to rotate, thus realizing the rotation of the loading device 10 and realizing the movement of the first specimen 11 on the second specimen 12.

[0061] The lifting and rotating device includes a bench 15, a hydraulic lifter 31, a rotating arm 30, and a suspension device. The hydraulic lifter 31 can be a cylindrical long column, installed on the bench 15, and can be lifted and lowered axially. The rotating arm 30 is installed on the hydraulic lifter 31 and can rotate around the hydraulic lifter 31. The rotating arm 30 is mainly used to place the suspension device and the end cap 4 connected to the suspension device in the corresponding positions at the start or end of the test. For example, when disassembling, the nut of the stud is removed, and the end cap 4 is lifted through the suspension device, the rotating arm 30, the hydraulic lifter 31, etc. At this time, the rotating arm 30 can rotate and drive the end cap 4 to rotate outwards, aiming to make the end cap 4 away from the cavity 7 for convenient other operations.

[0062] The suspension device includes a connecting rod 28 and a connector 29. The connector 29 is installed on the rotating arm 30. One end of the connecting rod 28 is fixedly installed on the connector 29, and the other end is fixedly installed on the end cap 4. Through the axial lifting of the hydraulic lifter 31, the axial movement of the end cap 4 can be achieved. Further, the connector 29 can be cylindrical, the axis of the connector 29 is parallel to the axis of the end cap 4, and the connector 29 can rotate around its own axis, so that the end cap 4 can be rotated to adjust the position, providing a suitable angle when disassembling and assembling the equipment. The connecting rod 28 can have only one, or two axially and one radially as shown in the figure, and the connector 29 is connected through the radial connecting rod 28.

[0063] Control system

[0064] The control system can include a temperature control device and a control console 1.

[0065] The temperature control device includes a temperature controller 16, an oil bath 14, a circulation pipeline 17, and a temperature measuring probe 3. The oil bath 14 is arranged outside the cavity 7. The oil bath 14 is used to hold the heat exchange medium, and provides a test temperature environment for the cavity 7 through the heat exchange medium. The temperature controller 16 has functions such as setting the target temperature, displaying the real-time oil bath temperature, automatically heating and cooling, etc. The temperature controller 16 can change the type and state of the heat exchange medium in the oil bath 14 through the circulation pipeline 17 to control the temperature environment, especially to achieve a low-temperature environment. For example, the heat exchange medium can be ethylene glycol, calcium chloride aqueous solution, liquid nitrogen, etc. The temperature measuring probe 3 can extend into the cavity 7 through the end cap 4 to detect the temperature environment in the cavity 7.

[0066] The control console 1 has functions such as real-time displaying the internal pressure of the pressure vessel, real-time displaying the internal temperature of the pressure vessel, setting the alarm temperature and pressure, automatically alarming for over-temperature and over-pressure, real-time displaying the temperature-pressure curve, displaying the temperature-pressure curve of the recent period, and saving the temperature-pressure curve data. The control console 1 can be connected to the aforementioned pressure transmitter 22 and temperature measuring probe 3 to monitor the test environment.

[0067] The electrochemical test system may include an electrochemical workstation 2 and an electrode system connected to the electrochemical workstation 2. The electrochemical workstation 2 is used to receive signals transmitted from the analysis electrode system. For example, the electrochemical workstation may have test functions such as polarization curves, electrochemical impedance spectra, and electrochemical noise. The electrode system may be a three-electrode system 23 including a working electrode, a reference electrode, and an auxiliary electrode, or a single-electrode system including a working electrode, or a two-electrode system including a working electrode and an auxiliary electrode. These three electrode systems all have the ability to work in high and low temperature, normal pressure, and high pressure environments. After the electrochemical workstation 2 is connected to the three-electrode system 23, the electrodes of the three-electrode system 23 can extend from the top of the end cap 4 into the cavity 7 to achieve combined friction and electrochemical testing. It can be understood that the specific composition and connection method of the electrochemical test system in this application are not limited, and the electrode system is not limited to the three-electrode system 23 either.

[0068] Compared with the existing solutions, the present invention has the following beneficial effects:

[0069] The pressure system and the temperature control system can realize environments of high and low temperatures, various pressures, media, and atmospheres in the friction and wear test. The function of electrochemical testing is realized through the electrochemical test system. The functions of lifting and moving the end cap are realized through the lifting and rotating device, which is convenient and labor-saving.

[0070] The above is the preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and refinements can be made without departing from the principle of this application, and these improvements and refinements should also be regarded as the protection scope of this application.
