Description

Technical Field

[0001] This invention relates to the field of bearing technology, and in particular to a hydrostatic bearing air supply system that can improve transient load-bearing capacity. Background Technology

[0002] Bearings are one of the core components of power machinery. Hydrostatic bearings have the characteristics of high load-bearing capacity and low friction loss. Compared with traditional hydrodynamic oil-lubricated bearings, the oil supply system can be eliminated and mechanical losses can be reduced. In particular, when high-pressure gas inside the power system is used as the bearing working medium, the power system can be simplified and energy efficiency can be improved. However, when hydrostatic bearings are subjected to strong external impacts (such as explosions, earthquakes, etc.), the rotor will rub against the bearing, causing bearing damage and equipment shutdown.

[0003] In this situation, a backup gas source is required. When the hydrostatic bearing is subjected to impact, the system should immediately switch to the backup high-pressure gas source to maintain the bearing's load-bearing capacity for a period of time. Generally, the working fluid of the hydrostatic bearing can be pre-pressurized and stored in a gas tank as a backup gas source. This method does not rely on complex real-time pressurization equipment and has good reliability. However, when using a high-temperature, easily phase-change gas as the working fluid of the hydrostatic bearing, the high-pressure working fluid in the tank will liquefy after dissipating heat to the outside, causing the temperature and pressure of the working fluid inside the tank to decrease and it to become a liquid phase, thus failing to serve as a backup gas source.

[0011] According to the present invention, a hydrostatic bearing air supply system that can improve transient load-bearing capacity is provided. The second air supply subsystem includes: a third pipeline and a check valve. The third pipeline is a three-way pipe, and the three ends of the three-way pipe are respectively connected to the first pipeline, the hydrostatic bearing and the air source.

[0026] The following is combined with Figures 1-2 The present invention describes a hydrostatic bearing air supply system that can improve transient load-bearing capacity.

[0027] The hydrostatic bearing air supply system for improving transient load-bearing capacity provided in this embodiment of the invention includes: a first air supply subsystem 10 and a second air supply subsystem 20. The first air supply subsystem 10 includes a first pipeline 11, a first switching valve 12, a reaction mechanism 13, and a degassing mechanism 14. The reaction mechanism 13 contains reactants and is connected to a first end of the first pipeline 11. The second end of the first pipeline 11 is used to connect to a hydrostatic bearing 30. The first switching valve 12 and the degassing mechanism 14 are both located in the first pipeline 11, with the degassing mechanism 14 situated between the reaction mechanism 13 and the first switching valve 12. The second air supply subsystem 20 is connected to the hydrostatic bearing 30 via the first pipeline 11. The first switching valve 12 is used to open when the hydrostatic bearing 30 is subjected to impact, allowing water vapor within the hydrostatic bearing 30 to enter the reaction mechanism 13 and react chemically with the reactants within the reaction mechanism 13 to generate water vapor and oxygen. The degassing mechanism 14 consumes oxygen and generates superheated steam.

[0028] Both the first air supply subsystem 10 and the second air supply subsystem 20 are connected to the hydrostatic bearing 30. The second air supply subsystem 20 supplies air to the hydrostatic bearing 30 during normal operation. When the hydrostatic bearing 30 is subjected to impact, the first air supply subsystem supplies air to the hydrostatic bearing 30. In this embodiment, the working fluid of the hydrostatic bearing 30 is water vapor. The hydrostatic bearing 30 can be a hydrostatic air-bearing bearing.

[0029] like Figure 1 and Figure 2 As shown, the rotor 40 is mounted on the static pressure bearing 30, and there is a gap between the rotor 40 and the static pressure bearing 30. After the water vapor provided by the first air supply subsystem 10 and the second air supply subsystem 20 enters the static pressure bearing 30, it is discharged through the gap between the rotor 40 and the static pressure bearing 30.

[0030] Specifically, the second gas supply subsystem 20 is connected to the first pipeline 11 between the first switching valve 12 and the static pressure bearing 30. Under normal operating conditions, the second gas supply subsystem 20 supplies water vapor to the static pressure bearing 30 through the first pipeline 11. When the static pressure bearing 30 is subjected to a strong external impact, the first switching valve 12 opens, and the water vapor in the second gas supply subsystem 20 enters the reaction mechanism 13 through the first pipeline 11 and the first switching valve 12. When the reactants in the reaction mechanism 13 come into contact with the high-temperature water vapor, a violent chemical reaction occurs, producing high-temperature, high-pressure water vapor and oxygen. In one embodiment, the reactant in the reaction mechanism 13 is hydrogen peroxide, which rapidly decomposes into high-temperature, high-pressure water vapor and oxygen under high temperature. The high-temperature, high-pressure water vapor and oxygen flow along the first pipeline 11 to the degassing mechanism 14, which consumes oxygen and generates superheated steam. In one embodiment, the degassing mechanism 14 is equipped with a metal hydride, which reacts with oxygen to generate metal oxides and water vapor. Metal oxides remain in the degassing mechanism 14. During the degassing process, the pressure and temperature of the vapor rise to form high-temperature and high-pressure superheated vapor, which enters the hydrostatic bearing 30 as the working fluid for the operation of the hydrostatic bearing 30, so as to ensure that the hydrostatic bearing 30 can operate normally and avoid the rotor 40 from colliding with the hydrostatic bearing 30, which would cause damage to the hydrostatic bearing 30.

[0031] The hydrostatic bearing gas supply system provided in this embodiment of the invention, which enhances transient load-bearing capacity, connects a second gas supply subsystem 20 to a first pipeline 11 between a first switching valve 12 and a hydrostatic bearing 30. Under normal operating conditions, the second gas supply subsystem 20 supplies steam to the hydrostatic bearing 30 through the first pipeline 11. When the hydrostatic bearing 30 is subjected to a strong external impact, the first switching valve 12 opens, and the steam from the second gas supply subsystem 20 enters the reaction mechanism 13 through the first pipeline 11 and the first switching valve 12. There, it reacts chemically with the reactants in the reaction mechanism 13, rapidly generating high-temperature, high-pressure steam and oxygen. The oxygen is then consumed by the degassing mechanism 14, forming high-temperature, high-pressure superheated steam higher than the normal gas supply pressure of the hydrostatic bearing 30, which then enters the hydrostatic bearing 30. This embodiment of the invention can instantly generate high-temperature, high-pressure superheated steam as a backup gas source the moment the hydrostatic bearing 30 is subjected to an external impact, significantly increasing the load-bearing capacity of the hydrostatic bearing 30, ensuring its normal operation, and preventing damage caused by collision between the hydrostatic bearing 30 and the rotor 40.

[0032] In some embodiments of the present invention, the reaction mechanism 13 includes a first container 131, which is in a vacuum state and contains reactants. The reactants and water vapor undergo a chemical reaction in the first container 131.

[0033] like Figure 1As shown, the first container 131 is in a vacuum state. The first container 131 is connected to the hydrostatic bearing 30 through the first pipe 11. The first switch valve 12 is located on the first pipe 11. When the hydrostatic bearing 30 is subjected to impact, the first switch valve 12 opens, and high-temperature water vapor enters the first container 131 through the first pipe 11. It reacts chemically with the reactants in the first container 131. The reactants can be hydrogen peroxide. Under high temperature, the hydrogen peroxide rapidly generates high-temperature and high-pressure water vapor and oxygen. The high-temperature and high-pressure water vapor and oxygen are degassed by the degassing mechanism 14 on the first pipe 11 to remove the oxygen. The pressure and temperature of the water vapor increase, and it becomes high-temperature and high-pressure superheated water vapor before entering the hydrostatic bearing 30.

[0034] In other embodiments of the present invention, the reaction mechanism 13 includes a first container 131 and a second container 132. The first container 131 is in a vacuum state and contains reactants, including hydrogen peroxide. The outlet of the first container 131 is connected to the first end of the first pipeline 11. The second container 132 contains reactants and high-pressure gas. The inlet of the first container 131 and the outlet of the second container 132 are connected through a second pipeline 133. The second pipeline 133 is equipped with a second switching valve 134, which is used to control the connection and disconnection between the first container 131 and the second container 132. The reactants and water vapor undergo a chemical reaction in the first container 131.

[0035] like Figure 2 As shown, when the hydrostatic bearing 30 is subjected to impact, the first switching valve 12 opens, and water vapor in the second gas supply subsystem 20 enters the first container 131 through the first pipeline 11, where it reacts chemically with the reactants in the first container 131. The reactants can be hydrogen peroxide, which rapidly generates high-temperature, high-pressure water vapor and oxygen under high temperature. If the reactants in the first container 131 are insufficient, the second switching valve 134 opens, and the reactants in the second container 132 enter the first container 131 to ensure sufficient reactants in the first container 131. The high-temperature, high-pressure water vapor and oxygen are degassed by the degassing mechanism 14 on the first pipeline 11, and the pressure and temperature of the water vapor increase, becoming high-temperature, high-pressure superheated water vapor before entering the hydrostatic bearing 30. It should be noted that the purpose of the high-pressure gas in the second container 132 is to ensure that when the pressure in the first container 131 increases, the reactants in the second container 132 can enter the first container 131 under the action of the high-pressure gas, thus ensuring sufficient reactants in the first container 131.

[0036] Based on the above embodiments, the reaction mechanism 13 may further include a gas supply component, which is connected to the second container 132. When the pressure in the second container 132 decreases, the gas supply component provides high-pressure gas to the second container 132 to stabilize the pressure in the second container 132 and ensure that the reactants in the second container 132 can enter the first container 131.

[0037] In one embodiment, such as Figure 2 As shown, the gas supply assembly includes a gas cylinder 135 and a fourth pipeline 136. The gas cylinder 135 stores high-pressure gas. The two ends of the fourth pipeline 136 are connected to the gas cylinder 135 and a second container 132, respectively, to supply gas to the second container 132, thereby stabilizing the gas pressure in the upper part of the second container 132. Furthermore, a third switching valve 137 is provided on the fourth pipeline 136, which is used to control the connection and disconnection between the gas cylinder 135 and the second container 132.

[0038] This invention utilizes a chemical reaction to generate high-temperature, high-pressure superheated steam, which can instantly produce the high-temperature, high-pressure superheated steam required for gas supply. The system has a fast response, high energy density, and compact size. Furthermore, the hydrostatic bearing 30 is typically used in closed systems, producing high-purity steam and preventing gaseous impurities from entering the system.

[0039] In some embodiments of the present invention, the degassing mechanism 14 includes a filter element on which a metal hydride is disposed. The metal hydride is capable of undergoing an oxidation reaction with oxygen to consume the oxygen generated within the reaction mechanism 13. The metal hydride includes titanium hydride, magnesium hydride, or lithium hydride.

[0040] In one embodiment, the filter element is coated with a metal hydride, which can react with oxygen through oxidation. Specifically, when high-temperature, high-pressure steam and oxygen pass through the filter element, the oxygen reacts with the metal hydride on the filter element to generate stable metal oxides and steam. Oxygen is consumed, generating more steam, further increasing the steam pressure. Simultaneously, the reaction releases heat, further raising the gas temperature and forming high-temperature, high-pressure superheated steam, thus creating the working fluid suitable for the operation of the hydrostatic bearing 30. This high-temperature, high-pressure superheated steam then enters the hydrostatic bearing 30, supplying gas to it. It should be noted that the content of the metal hydride and the gap in the filter element are set according to actual conditions to completely consume the generated oxygen.

[0041] Based on the above embodiments, further, multiple filter elements are provided, spaced apart along the first end to the second end of the first pipeline 11. Each filter element is provided with a metal hydride to consume all the oxygen and prevent oxygen from entering the hydrostatic bearing 30. In one embodiment, the filter element is a filter screen. In another embodiment, the filter element is a wire mesh, with multiple layers of wire mesh evenly arranged within the first pipeline 11.

[0042] In some embodiments of the present invention, the second gas supply subsystem 20 includes a third pipeline 21 and a check valve 22. The third pipeline 21 is a three-way pipe, with its inlet end connected to a gas source and its other two ends connected to the first pipeline 11 and the static pressure bearing 30, respectively. Further, the check valve 22 is located on the third pipeline 21, near the gas source, and is used to control the connection and disconnection between the gas source and the third pipeline 21. Under normal operating conditions, the check valve 22 is open, and water vapor enters the static pressure bearing 30 through the inlet end of the third pipeline 21. In the event of an impact, the pressure between the check valve 22 and the static pressure bearing 30 is greater than the pressure between the check valve 22 and the gas source, causing the check valve 22 to close, the first switching valve 12 to open, and water vapor to enter the reaction mechanism 13 through the third pipeline 21 and the first pipeline 11.

[0043] In some embodiments of the present invention, the hydrostatic bearing air supply system that can improve transient load-bearing capacity also includes a controller and a vibration sensor. The vibration sensor is disposed on the hydrostatic bearing 30 and is used to acquire the vibration information of the hydrostatic bearing. The vibration sensor and the first switching valve 12 are both electrically connected to the controller, and the controller controls the opening of the first switching valve 12 according to the vibration information.

[0044] Furthermore, the first gas supply subsystem 10 also includes a pressure sensor, which is located inside the reaction mechanism 13 and is used to acquire pressure information inside the reaction mechanism 13. The pressure sensor is electrically connected to the controller, and the controller controls the closing of the first switching valve 12 and the opening of the check valve 22 based on the pressure information inside the reaction mechanism 13.

[0045] Specifically, a vibration sensor is installed on the hydrostatic bearing 30 to acquire its vibration information. If the vibration information exceeds a preset value, it is confirmed that the hydrostatic bearing 30 has been subjected to an external impact. When the hydrostatic bearing 30 is subjected to an external impact, the controller, based on the vibration information acquired by the vibration sensor, controls the first switching valve 12 to open. Water vapor passes through the first switching valve 12, the degassing mechanism 14, and enters the reaction mechanism 13 to react. The reaction products, after passing through the degassing mechanism 14, increase in temperature and pressure, forming high-temperature, high-pressure superheated steam, which finally enters the hydrostatic bearing 30 to supply air to it. At this time, the pressure between the check valve 22 and the hydrostatic bearing 30 is greater than the pressure between the check valve 22 and the air source, causing the check valve 22 to close.

[0046] As the first gas supply subsystem 10 operates, the reactants (hydrogen peroxide) in the reaction mechanism 13 are continuously consumed, while the metal hydrides on the degassing mechanism 14 continuously react with oxygen. When the reactants are completely consumed, the reaction is interrupted, the pressure in the reaction mechanism 13 decreases, and it falls below the normal gas supply pressure of the hydrostatic bearing 30. The controller controls the first switching valve 12 to close and simultaneously controls the check valve 22 to open, so that the second gas supply subsystem 20 can operate normally.

[0047] The operating time of this embodiment of the invention is limited, and it can protect the hydrostatic bearing 30 from colliding with the rotor 40 for a short period of time after the impact occurs. The air supply system of this invention has a simple structure, requires no additional heating or pressurization equipment, and adjusts the opening and closing of the first switching valve 12 and the check valve 22 only according to the impact information (vibration information) and pressure information, thus having good reliability.

[0048] It should be noted that when the first switch valve 12 is closed, the degassing mechanism 14 can be replaced, such as by replacing the filter element; reactants can be added to the reaction mechanism 13 and a vacuum can be drawn, thereby enabling online maintenance without shutting down the system.

[0049] In this embodiment of the invention, hydrogen peroxide undergoes a violent thermal decomposition upon contact with high-temperature water vapor, generating high-temperature, high-pressure water vapor and oxygen. When the hydrostatic bearing 30 is subjected to an impact load, the hydrogen peroxide reaction is instantly initiated and maintained to generate the high-temperature, high-pressure water vapor required by the hydrostatic bearing 30. The generated oxygen is consumed by the degassing mechanism 14, while more water vapor is generated and the water vapor pressure is increased. Simultaneously, the reaction releases heat and heats the water vapor to form superheated water vapor, thereby generating high-temperature, high-pressure superheated water vapor that is significantly higher than the normal gas supply pressure of the hydrostatic bearing 30 in a short period of time, preventing the rotor 40 from colliding with the hydrostatic bearing 30.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
