Description

Technical Field

[0001] The present invention relates to the technical field of steam power systems, and in particular to a condensation device, a condensation system and a condensation noise reduction method. Background Art

[0002] Steam power system, as an indispensable component of modern marine power generation equipment, its operating safety and reliability are directly related to the normal operation and maintenance of the entire equipment system. In this complex power system, the condensate system plays a vital role. The main responsibility of the condensate system is to continuously and efficiently extract condensate from the condenser and transport the condensate to the water supply system by means of boosting, so as to maintain the continuous and stable circulation of the thermal working medium of the steam power system. In view of this core function of the condensate system, its normal and stable operating state is extremely important to ensure the overall safety and stability of the steam power system.

[0003] The condensate pump is the core component of the condensate system, and its operating status affects the efficiency of the entire condensate system. However, in the actual operation of the steam power system, the condensate pump faces many challenges. On the one hand, the circulating water system, the condensate system and the vacuum pump work together to maintain the high vacuum state of the condenser. In this state, the supercooling degree of the deoxygenated condensate is extremely low and is almost saturated, which undoubtedly increases the difficulty of the condensate pump. On the other hand, due to the spatial layout inside the hull, the relative position difference between the condenser and the main equipment of the condensate system is limited, resulting in a serious lack of inlet filling height of the condensate pump. The combined effect of these two factors makes it very easy for the condensate pump to cavitate during operation.

[0004] The emergence of cavitation problems will not only significantly reduce the output head and working efficiency of the condensate system, but also cause an increase in vibration and noise, which will have a great impact on the safe operation and low-noise environment of the power unit. In order to address this problem, the existing condensate pump vibration reduction design mainly uses hydraulic design to improve the condensate pump's anti-cavitation ability. However, this method requires complex hydraulic calculations and optimization analysis of specific pumps, which is extremely difficult to design and often difficult to achieve the desired effect.

[0025] Combine the following Figure 1 to Figure 2 The present invention describes a condensation device, a condensation system and a condensation noise reduction method.

[0026] The condensate device provided in the embodiment of the present invention includes a condensate pump 1, a vulcanized rubber layer 12, a data processing module 2 and a pressure regulating member 3. The vulcanized rubber layer is arranged on the periphery of the condensate pump. Specifically, the condensate pump includes a pump, a housing and a base 11, the housing cover is arranged on the periphery of the pump, and the pump and the base are installed on the base 11. In one embodiment, the vulcanized rubber layer may be arranged on the periphery of the housing. In another embodiment, the vulcanized rubber layer 12 is arranged on the periphery of the base 11. The pump has a pump shaft, and the vulcanized rubber layer may also be arranged on the periphery of the pump. Furthermore, at least two fluid channels are arranged in the vulcanized rubber layer 12, and the stiffness of the vulcanized rubber layer 12 can be adjusted by inputting or outputting fluid into the fluid channel. The fluid channel in the embodiment of the present invention may be a vein-type fluid channel.

[0027] Furthermore, each fluid channel is connected to the pressure regulating component 3 through a pipeline. The pressure regulating component 3 is used to adjust the pressure in each fluid channel. The fluid pressure in the fluid channel can be increased or decreased as needed to adjust the stiffness value of the vulcanized rubber layer 12, thereby reducing the vibration noise of the condensate pump and improving the smoothness of the operation of the condensate pump.

[0028] To achieve automatic control, the condensate pump 1 and the pressure regulating component 3 in the embodiment of the present invention are respectively connected to the data processing module 2 through wired or wireless communication. The data processing module 2 is used to receive the operating parameters of the condensate pump 1, such as the vibration acceleration level of the condensate pump, the rotational speed and power of the condensate pump 1, and the pressure information in each fluid channel, and determine the target pressure in each fluid channel based on the parameters of the vulcanized rubber layer 12; control the pressure regulating component 3 to adjust the fluid pressure in each fluid channel so that the fluid pressure in each fluid channel reaches the target pressure. This process ensures that the condensate pump 1 always maintains the best operating state under different working conditions and reduces the vibration noise of the condensate pump.

[0029] The condensate device provided in the embodiment of the present invention is provided with a vulcanized rubber layer 12 on the outer periphery of the condensate pump, and with at least two fluid channels in the vulcanized rubber layer 12, each of which is connected to the pressure regulating component 3. The data processing module 2 determines the target pressure of each fluid channel based on the operating parameters of the condensate pump 1 and the parameters of the vulcanized rubber layer 12, and controls the pressure regulating component 3 to adjust the fluid pressure in each fluid channel to the target pressure, and adjusts the stiffness of the vulcanized rubber layer 12, thereby reducing the vibration noise of the condensate pump and making the condensate pump 1 run stably.

[0030] like Figure 1 As shown, the condensate pump 1 includes a base 11, a vulcanized rubber layer 12 is provided on the periphery of the base 11, and at least two fluid channels are provided in the vulcanized rubber layer 12. The data processing module 2 is used to receive the operating parameters of the condensate pump 1, such as the vibration acceleration level of the base 11, the rotation speed and power of the condensate pump 1 and the pressure information in each fluid channel, and determine the target pressure in each fluid channel based on the parameters of the vulcanized rubber layer 12; the pressure regulating member 3 is controlled to adjust the fluid pressure in each fluid channel so that the fluid pressure in each fluid channel reaches the target pressure. This process ensures that the condensate pump 1 always maintains the best operating state under different working conditions, adjusts the stiffness of the vulcanized rubber layer 12 on the periphery of the base 11, and reduces the vibration noise of the base 11.

[0031] Furthermore, the data processing module 2 has a signal input terminal 21, which is connected to the condensate pump 1 through a cable to achieve communication, and the operating parameters of the condensate pump 1 (such as the acceleration level, rotation speed, power of the base 11, and the fluid pressure of the fluid channel) are transmitted to the data processing module 2 for processing through the signal input terminal 21. The data processing module 2 determines the target pressure in each fluid channel according to the operating parameters of the condensate pump 1 and the parameters of the vulcanized rubber layer 12 (mass, thickness, etc.).

[0032] The pressure regulating member 3 is provided with a pressure signal receiving terminal 34, and the data processing module 2 has a signal output terminal 22, which is connected to the pressure signal receiving terminal 34 through a cable, and the target pressure in each fluid channel determined by the data processing module 2 is transmitted to the pressure signal receiving terminal 34 through the signal output terminal 22. Further, the pressure regulating member 3 includes at least two pressure output terminals, each pressure signal output terminal 22 is connected to a fluid channel, and based on the target pressure in each fluid channel, the pressure information in each fluid channel is adjusted until the target pressure is reached.

[0033] Specifically, the pressure regulating member 3 is also provided with a boosting end 35 and a pressure relief end 36, and each fluid channel is connected to the boosting end 35 and the pressure relief end 36 respectively through the pressure output end, wherein the boosting end 35 is used to be connected to the pressure source, and when the pressure in the fluid channel needs to be increased, the boosting end 35 is connected to the fluid channel through the pressure output end, and the fluid enters the fluid channel through the boosting end 35, the pressure output end, and the pipeline, thereby increasing the fluid pressure in the fluid channel. The pressure relief end 36 is connected to the external environment, and when the pressure in the fluid channel needs to be reduced, the fluid channel is connected to the pressure relief end 36 through the pressure output end, and the pressure is released to the external environment to reduce the fluid pressure in the fluid channel.

[0034] The condensation device provided in the embodiment of the present invention also includes a first switch valve and a second switch valve, and the first switch valve and the second switch valve are respectively connected to the pressure signal receiving end 34 by wired or wireless communication. Specifically, the pressure signal receiving end 34 of the pressure regulating member 3 receives the pressure signal of the data processing module 2. When the pressure in the fluid channel needs to be increased, the first switch valve is controlled to open, and the boosting end 35 is connected to the fluid channel through the pressure output end to achieve boosting. When the pressure in the fluid channel needs to be reduced, the second switch valve is controlled to open, and the pressure relief end 36 is connected to the fluid channel through the pressure output end to relieve pressure. The first switch valve in the embodiment of the present invention can be arranged at the end of the boosting end 35, and the second switch valve can be arranged at the end of the pressure relief end 36.

[0035] In the embodiment of the present invention, at least two fluid channels are provided in the vulcanized rubber layer 12, and the target pressure in each fluid channel can be different, that is, the pressure increase or pressure relief in each fluid channel can be the same or different. Based on this, in the embodiment of the present invention, an on-off valve is provided in each fluid channel, and the on-off valve is communicatively connected with the pressure signal receiving end 34, and the on-off valve is used to control the connection and disconnection between the pressure output end and the fluid channel.

[0036] In one embodiment, there are two fluid channels, namely a first fluid channel 14 and a second fluid channel 15. Figure 1As shown, a first on-off valve is provided in the first fluid channel 14, and a second on-off valve is provided in the second fluid channel 15; there are two pressure output ends, namely a first pressure output end 31 and a second pressure output end 32, wherein the first pressure output end 31 is connected to the first fluid channel 14, and the second pressure output end 32 is connected to the second fluid channel 15. When the target pressure in the first fluid channel 14 and the target pressure in the second fluid channel 15 are different, the first on-off valve and the second on-off valve can be used for control. For example, when it is necessary to increase the pressure in the first fluid channel 14 and the second fluid channel 15, but the target pressure values ​​of the two are different, the pressure increasing end 35 is connected to the first fluid channel 14 through the first pressure output end 31, and the pressure increasing end 35 is connected to the second fluid channel 15 through the second pressure output end 32. When the target pressure is reached in the first fluid channel 14, the first on-off valve is controlled to close and the pressure increase is stopped; at this time, the pressure in the second fluid channel 15 can continue to be increased until the second on-off valve is closed when the target pressure is reached.

[0037] The condensation device provided in the embodiment of the present invention further includes a pressure sensor, and each fluid channel is provided with a pressure sensor for obtaining pressure information in the fluid channel. The condensation pump 1 further includes a control unit 13, and each pressure sensor is connected to the control unit 13 by wired or wireless communication, and the control unit 13 is used to receive pressure information of each pressure sensor. The control unit 13 is connected to the signal input terminal 21 of the data processing module 2 via a cable, and the control unit 13 can transmit the pressure information of each pressure sensor to the data processing module 2 for processing.

[0038] The condensation device provided in the embodiment of the present invention further includes a vibration sensor, which is disposed at a position to be measured on the base 11 and is used to obtain vibration data of the base 11, such as vibration acceleration, etc. Further, the vibration sensor is connected to the control unit 13 via wired or wireless communication, and the control unit 13 receives the vibration data of the vibration sensor and transmits it to the data processing module 2 for processing.

[0039] The condensate device provided in the embodiment of the present invention further includes a display component, which is connected to the data processing module 2 via wired or wireless communication, and is used to display the operating parameters of the condensate pump 1 and the current pressure and target pressure in each fluid channel.

[0040] The data processing module 2 in the embodiment of the present invention stores the mass, thickness and number of fluid channels of the vulcanized rubber layer 12, the target value of the vibration acceleration level at the measuring point on the machine base 11, the characteristic table of the condensate pump 1, the stiffness characteristic table of the vulcanized rubber layer 12 and the modified Markov model equation. The characteristic table of the condensate pump 1 describes the relationship between the efficiency, speed and power of the condensate pump 1, that is, the efficiency value of the condensate pump 1 can be obtained according to the speed of the condensate pump 1 and the power of the condensate pump 1. The stiffness characteristic table of the vulcanized rubber layer 12 describes the relationship between the mass, thickness, number of fluid channels and fluid pressure of the vulcanized rubber layer 12, that is, the stiffness of the vulcanized rubber layer 12 can be obtained according to the mass, thickness, number of fluid channels and fluid pressure in the fluid channels of the vulcanized rubber layer 12. The modified Markov model equation describes the relationship between the vibration acceleration level at the measuring point on the machine base 11 and the rotational speed of the condensate pump 1, the efficiency of the condensate pump 1, the stiffness of the vulcanized rubber layer 12, and the fluid pressure of the fluid channel, that is, the target pressure of the fluid channel fluid can be obtained based on the rotational speed of the condensate pump 1, the efficiency of the condensate pump 1, the stiffness of the vulcanized rubber layer 12, the target value of the vibration acceleration level at the measuring point on the machine base 11, and the randomness correction coefficient.

[0041] The data processing module 2 receives the rotation speed of the condensate pump 1, the power of the condensate pump 1 and the fluid pressure in each fluid channel sent by the control unit 13 of the condensate pump 1. The data processing module 2 calculates the target pressure of the fluid in each fluid channel according to the modified Markov model equation. The data processing module 2 sends the target pressure signal in each fluid channel to the pressure regulating component 3. When the target pressure is different from the actual pressure of the fluid in the fluid channel, the pressure regulating component 3 increases or decreases the pressure through the pressure output end until the target pressure in the corresponding fluid channel is reached.

[0042] In one embodiment, the data processing module 2 receives the rotation speed and power signals of the condensate pump 1 transmitted by the control unit 13 of the condensate pump 1 through the cable, wherein the mass and thickness of the vulcanized rubber layer 12 are 8 kg and 8 mm, the number of fluid channels is 4, the target value of the vibration acceleration level at the measuring point on the machine base 11 is 105 dB (10 Hz-10 kHz), the vibration characteristic table of the condensate pump 1, the stiffness characteristic table of the vulcanized rubber layer 12 and the modified Markov model equation calculate the target pressure value of the fluid in the fluid channel to be 5 MPa, the data signal output end 22 of the data processing module 2 transmits the target pressure value signal of the fluid in the fluid channel to the pressure signal receiving end 34 of the pressure regulating component 3 through the cable, and the pressure regulating component 3 increases or decreases the pressure through the first pressure output end 31 until the fluid pressure in the first fluid channel 14 reaches the target pressure value of 5 MPa; and increases or decreases the pressure through the second pressure output end 32 until the fluid pressure in the second fluid channel 15 reaches the target pressure value of 5 MPa. The fluid pressure in each fluid channel reaches the target pressure, and the rigidity adjustment of the vulcanized rubber layer 12 is completed, thereby reducing the vibration noise of the machine base 11 and allowing the condensate pump 1 to operate stably.

[0043] An embodiment of the present invention further provides a water condensation system, comprising a water condensation device as in any of the above embodiments.

[0044] Based on the water condensation device in any of the above embodiments, Figure 2 As shown, an embodiment of the present invention also provides a condensate noise reduction method, including: step 100, obtaining the rotation speed of the condensate pump, the efficiency of the condensate pump, the stiffness of the vulcanized rubber layer, and the target value of the vibration acceleration level at the test point. Specifically, the data processing module is connected to the condensate pump, and the rotation speed and power of the condensate pump can be obtained. The condensate pump characteristic table describes the relationship between the efficiency of the condensate pump and the rotation speed of the condensate pump and the power of the condensate pump. Based on the condensate pump characteristic table, the efficiency of the condensate pump can be obtained. The stiffness characteristic table of the vulcanized rubber layer describes the relationship between the stiffness of the vulcanized rubber layer and the mass, thickness, number of fluid channels and pressure of the fluid in each fluid channel of the vulcanized rubber layer. The stiffness of the vulcanized rubber layer can be determined based on the stiffness characteristic table of the vulcanized rubber layer. Specifically, the number of fluid channels set in the vulcanized rubber layer is obtained, and the current pressure in each fluid channel is obtained by a pressure sensor; the thickness and mass of the vulcanized rubber layer are obtained; based on the number of fluid channels, the current pressure in each fluid channel, the thickness and mass of the vulcanized rubber layer, the stiffness of the vulcanized rubber layer is determined. Based on the vibration sensor, the acceleration at the corresponding test point, such as the pump shaft, housing and base, is obtained according to the setting position of the vulcanized rubber layer, and then the target value of the acceleration level of the test point is determined.

[0045] Step 200, based on the Markov model equation, determine the target fluid pressure in the fluid channel. The Markov model equation describes the relationship between the vibration acceleration level at the test point and the condensate pump speed, the condensate pump efficiency, the vulcanized rubber layer stiffness, and the fluid pressure of the fluid channel. Based on the condensate pump speed, the condensate pump efficiency, the stiffness of the vulcanized rubber layer, and the target value of the vibration acceleration level at the test point on the pump shaft, the target fluid pressure of the fluid channel is determined through the Markov model equation.

[0046] Step 300, based on the target fluid pressure, controls the pressure regulating component to adjust the pressure of each fluid channel to the target fluid pressure, such as inputting or outputting fluid into the fluid channel, thereby increasing or decreasing the pressure in the fluid channel to reach the target fluid pressure, thereby adjusting the stiffness of the vulcanized rubber layer, thereby reducing vibration noise and allowing the condensate pump to operate stably.
