[0002] Ultrahigh-pressure pumps are designed to operate continuously 24 / 7 under ultrahigh-pressure conditions, with multiple pumps operating redundantly. If the active ultrahigh-pressure pump fails, the backup pump will be activated, resulting in interruptions in the continuous ultrahigh-pressure output. This makes it impossible to guarantee the continuity and stability of the system's ultrahigh-pressure output. Therefore, a safety monitoring system is required to predict the status of the active ultrahigh-pressure pump, allowing for timely switching to the backup pump and achieving seamless pressure output.

[0003] Existing detection methods for ultra-high pressure pumps are usually temperature and pressure measurements, and these are discrete detection methods. There is no multi-dimensional detection method, no corresponding multi-dimensional data model to analyze and judge the detection data. It is impossible to predict the operation and development trend of the ultra-high pressure pump in advance, and it is impossible to provide fault repair data in advance and analyze and judge the repair solution. It can only serve as an alarm after a fault occurs, and cannot guarantee the continuous operation of the ultra-high pressure pump. Therefore, there is an urgent need for an ultra-high pressure pump safety monitoring system to monitor the operating status of the ultra-high pressure pump in real time and ensure its safe operation.

[0035] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0036] Example 1

[0037] This embodiment provides an ultra-high pressure pump safety monitoring system, such as Figure 1 、 Figure 2 and Figure 3 As shown, it includes a high-pressure oil pump 1, a supercharger 10 connected to the high-pressure oil pump 1, a central processing unit module, and a vibration monitoring module, a temperature monitoring module, an ultrasonic detection module, a memory module, a display module and an alarm module electrically connected to the central processing unit module.

[0038] like Figure 1 and Figure 3 As shown, the oil inlet of the high-pressure oil pump 1 is connected to the oil inlet pipe 6, and the oil outlet of the high-pressure oil pump 1 is connected to the oil outlet pipe 7. The vibration monitoring module includes an oil inlet vibration frequency sensor 2 and an oil outlet vibration frequency sensor 3. The oil inlet vibration frequency sensor 2 is installed at the end of the oil inlet pipe 6 connected to the oil inlet of the high-pressure oil pump 1, and the oil outlet vibration frequency sensor 3 is installed at the end of the oil outlet pipe 7 connected to the oil outlet of the high-pressure oil pump 1. The oil inlet vibration frequency sensor 2 and the oil outlet vibration frequency sensor 3 are used to collect the vibration frequency of the oil inlet and oil outlet at the oil inlet and oil outlet of the high-pressure oil pump 1 respectively, collect and store the vibration data at a collection speed of 20 vibration frequencies per second, and transmit the collected vibration data to the central processing unit module. The temperature monitoring module includes a left infrared temperature detector 4 and a right infrared temperature detector 5. The left infrared temperature detector 4 and the right infrared temperature detector 5 are symmetrically arranged on the left and right sides of the high-pressure oil pump 1. The left infrared temperature detector 4 and the right infrared temperature detector 5 are used to collect the temperature distribution on the left and right sides of the high-pressure oil pump 1 respectively, store them at a frequency of 10 frames per second, and transmit the collected temperature distribution data to the central processing unit module.

[0039] like Figure 2 and Figure 3As shown, the ultrasonic detection module includes a left ultrasonic detector 8 and a right ultrasonic detector 9, which are respectively positioned on the left and right sides of the supercharger 10. The left ultrasonic detector 8 and the right ultrasonic detector 9 perform high-frequency scanning of the supercharger 10 on both sides, respectively, and record acoustic image data of the supercharger 10, storing it at a frequency of 10 frames per second. The resulting acoustic image data is then transmitted to the central processing unit module.

[0040] The memory module stores the vibration frequency data and temperature distribution data of the high-pressure oil pump 1, and the vibration frequency data and temperature distribution data are stored in the form of a vibration frequency graph and a temperature distribution graph, respectively. The memory module also stores the acoustic image data of the supercharger, and stores it in the form of an acoustic image graph. Moreover, the vibration frequency data, temperature distribution data and acoustic image data stored in the memory module include three data ranges: normal, diseased and faulty. The various data stored in the memory module, including the three data ranges of normal, diseased and faulty, are collected, sorted, summarized and optimized based on the actual operating experience of the high-pressure oil pump 1 and the supercharger 10. The various data stored in the memory module can be continuously modified and improved, and the division of the three data ranges of normal, diseased and faulty can also be continuously modified and improved. The central processing unit module is used to receive the vibration frequency graph, infrared imaging graph, and ultrasonic imaging graph transmitted by the vibration monitoring module, temperature monitoring module, and ultrasonic detection module, and compare them with the vibration frequency graph, temperature distribution graph, and acoustic imaging graph stored in the memory module. Based on the comparison results, the central processing unit module generates three types of judgment data: normal, faulty, and faulty. After the judgment data is generated, it is displayed to the outside through the display module. In this way, the operating status of the high-pressure oil pump 1 and the supercharger 10 can be clearly understood through the display module. The display module often uses a display.

[0041] In this embodiment, the alarm module includes an audible and visual alarm and a GSM alarm. The audible and visual alarm can emit both audible and visual alarm signals at the same time, and has the advantage of a good alarm effect. The audible and visual alarm is set in two places, one is located at the high-pressure oil pump 1, which is used for on-site alarm, and the other is located in the control room where the central processing unit module, memory module and display module are placed, which is used to alarm the centralized control personnel. The GSM alarm is used to make calls to preset telephone numbers and send messages for remote alarms. When the central processing unit module determines that the high-pressure oil pump 1 and the supercharger 10 are in a sick or faulty state, it controls the audible and visual alarm and the GSM alarm to enter the site, centralized control and remote alarm.

[0042] The present invention operates as follows: An ultra-high-pressure pump comprises a high-pressure oil pump 1 and a supercharger 10. The present invention utilizes infrared thermal imaging technology to measure and obtain a temperature distribution map, or infrared image, of the high-pressure oil pump 1, and ultrasonic imaging technology to measure and obtain an ultrasonic image of the supercharger 10. Simultaneously, a vibration frequency map of the oil inlet and outlet of the high-pressure oil pump 1 is measured and obtained. The present invention stores the vibration frequency map and temperature distribution map of the high-pressure oil pump 1 in a memory module, along with an acoustic image map of the supercharger. The vibration frequency data, temperature distribution data, and acoustic image data stored in the memory module include three data ranges: normal, faulty, and malfunctioning. The central processing unit module compares the received vibration frequency map, infrared image map, and ultrasonic image map with the vibration frequency map, temperature distribution map, and acoustic image map stored in the memory module. Based on the overlap between the received and stored data, the operating status of the high-pressure oil pump 1 and supercharger 10 is determined. The operating status of the high-pressure oil pump 1 and supercharger 10 is also categorized as normal, faulty, and malfunctioning. The central processing unit module displays the operating status of the high-pressure oil pump 1 and the supercharger 10 to the outside through the display module, so that the staff can clearly know the operating status of the high-pressure oil pump 1 and the supercharger 10 through the display module.

[0043] Therefore, the present invention can monitor the operating status of the ultra-high pressure pump in real time, display the operating status of the ultra-high pressure pump in real time, and determine whether the ultra-high pressure pump is operating normally.

[0044] Example 2

[0045] This embodiment provides an ultra-high pressure pump safety monitoring system, such as Figure 1 、 Figure 2 and Figure 4 As shown, it includes a high-pressure oil pump 1, a supercharger 10 connected to the high-pressure oil pump 1, a central processing unit module, a vibration monitoring module, a temperature monitoring module, an ultrasonic detection module, a memory module, a display module, an alarm module, a wireless communication module, a remote monitoring module, an ambient temperature detection module and a running time module, wherein the vibration monitoring module, the temperature monitoring module, the ultrasonic detection module, the memory module, the display module, the alarm module, the ambient temperature detection module and the running time module are all electrically connected to the central processing unit module.

[0046] like Figure 1 and Figure 4As shown, the oil inlet of the high-pressure oil pump 1 is connected to the oil inlet pipe 6, and the oil outlet of the high-pressure oil pump 1 is connected to the oil outlet pipe 7. The vibration monitoring module includes an oil inlet vibration frequency sensor 2 and an oil outlet vibration frequency sensor 3. The oil inlet vibration frequency sensor 2 is installed at the end of the oil inlet pipe 6 connected to the oil inlet of the high-pressure oil pump 1, and the oil outlet vibration frequency sensor 3 is installed at the end of the oil outlet pipe 7 connected to the oil outlet of the high-pressure oil pump 1. The oil inlet vibration frequency sensor 2 and the oil outlet vibration frequency sensor 3 are used to collect the vibration frequency of the oil inlet and oil outlet at the oil inlet and oil outlet of the high-pressure oil pump 1 respectively, collect and store the vibration data at a collection speed of 20 vibration frequencies per second, and transmit the collected vibration data to the central processing unit module. The temperature monitoring module includes a left infrared temperature detector 4 and a right infrared temperature detector 5. The left infrared temperature detector 4 and the right infrared temperature detector 5 are symmetrically arranged on the left and right sides of the high-pressure oil pump 1. The left infrared temperature detector 4 and the right infrared temperature detector 5 are used to collect the temperature distribution on the left and right sides of the high-pressure oil pump 1 respectively, store them at a frequency of 10 frames per second, and transmit the collected temperature distribution data to the central processing unit module.

[0047] like Figure 2 and Figure 4 As shown, the ultrasonic detection module includes a left ultrasonic detector 8 and a right ultrasonic detector 9, which are respectively positioned on the left and right sides of the supercharger 10. The left ultrasonic detector 8 and the right ultrasonic detector 9 perform high-frequency scanning of the supercharger 10 on both sides, respectively, and record acoustic image data of the supercharger 10, storing it at a frequency of 10 frames per second. The resulting acoustic image data is then transmitted to the central processing unit module.

[0048] The memory module stores vibration frequency data and temperature distribution data for the high-pressure oil pump 1, stored in the form of a vibration frequency graph and a temperature distribution graph, respectively. The memory module also stores acoustic image data for the supercharger, stored in the form of an acoustic image graph. Furthermore, the vibration frequency data, temperature distribution data, and acoustic image data stored in the memory module include three data ranges: normal, defective, and faulty. The central processing unit module is configured to receive the vibration frequency graph, infrared image graph, and ultrasonic image graph transmitted by the vibration monitoring module, temperature monitoring module, and ultrasonic detection module, and compare them with the vibration frequency graph, temperature distribution graph, and acoustic image graph stored in the memory module. Based on the comparison results, the CPU module generates three types of discrimination data: normal, defective, and faulty. Once the discrimination data is generated, it is displayed to the user via the display module. This allows personnel to clearly understand the operating status of the high-pressure oil pump 1 and supercharger 10 through the display module, which often utilizes a display.

[0049] In this embodiment, the alarm module includes an audible and visual alarm and a GSM alarm. The audible and visual alarm can emit both audible and visual alarm signals at the same time, and has the advantage of a good alarm effect. The audible and visual alarm is set in two places, one is located at the high-pressure oil pump 1, which is used for on-site alarm, and the other is located in the control room where the central processing unit module, memory module and display module are placed, which is used to alarm the centralized control personnel. The GSM alarm is used to make calls to preset telephone numbers and send messages for remote alarms. When the central processing unit module determines that the high-pressure oil pump 1 and the supercharger 10 are in a sick or faulty state, it controls the audible and visual alarm and the GSM alarm to enter the site, centralized control and remote alarm.

[0050] like Figure 4 As shown, the wireless communication module is used to connect the central processing unit module and the remote monitoring module. The wireless communication module can be any one or more of a 4G communication module, a 5G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA module, and a ZigBee module. The remote monitoring module can be any one or more of a mobile phone, an iPad, or a computer. The central processing unit module can transmit the content displayed by the display module to the remote monitoring module via the wireless communication module, facilitating remote monitoring of the ultra-high pressure pump's operating status.

[0051] In this embodiment, the ambient temperature detection module uses a temperature sensor or thermometer, which is installed at the installation location of the high-pressure oil pump 1, and is used to detect the ambient temperature at the high-pressure oil pump 1 and transmit the detected ambient temperature to the central processing unit module. The operating time module is used to record the operating time of the high-pressure oil pump 1 and the supercharger 10, and transmit the recorded operating time to the central processing unit module. The temperature distribution data of the high-pressure oil pump 1 stored in the memory module is divided into multiple groups according to the ambient temperature of the high-pressure oil pump 1. When the central processing unit module compares the temperature data of the high-pressure oil pump 1, it performs group comparison according to the ambient temperature of the high-pressure oil pump 1. The vibration frequency data of the high-pressure oil pump 1 and the acoustic image data of the supercharger 10 stored in the memory module are divided into multiple groups according to the operating time of the high-pressure oil pump 1 and the supercharger 10. When the central processing unit module compares the vibration data of the high-pressure oil pump 1 and the acoustic image data of the supercharger 10, it performs group comparison according to the operating time of the high-pressure oil pump 1 and the supercharger 10.

[0052] Compared to Example 1, this embodiment takes into account the impact of the ambient temperature of the high-pressure oil pump 1 when comparing its temperature distribution. It also considers the impact of the varying degrees of wear and tear on the high-pressure oil pump 1 and supercharger 10 due to their different operating times when comparing the vibration frequencies at the oil inlet and outlet of the high-pressure oil pump 1 and the acoustic image of the supercharger 10. This makes the judgment results drawn by the central processing unit module more accurate, and the equipment operating status displayed by the operator on the display module more precise.
