Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ocean engineering, and in particular to a power end lubrication system and method suitable for an ocean fracturing pump. BACKGROUND

[0002] The fracturing pump is the core equipment of fracturing operation, and its performance and reliability directly determine the success and efficiency of the fracturing operation. The fracturing operation can be divided into land fracturing and ocean fracturing according to the operation area. At present, the fracturing pump is not specially designed in structure for the two different operation areas.

[0003] With the increasing development of China's ocean oil and gas field, the number of ocean fracturing operations is increasing, and the requirements for ocean fracturing equipment are becoming higher and higher. In view of the limited equipment space and harsh working environment (high temperature, high corrosion, etc.) of offshore platforms, more stringent requirements are put forward for the continuous operation ability and intelligent monitoring ability of the fracturing pump on the offshore platform, so as to reduce the unplanned downtime of the fracturing pump as much as possible and improve the overall operation efficiency. The power end lubrication system of the fracturing pump is the core auxiliary system to ensure the normal operation of the fracturing pump. A stable and reliable power end lubrication system can avoid high-temperature ablation of the bearing bush, bearing and other extreme damage such as fracture of the main load-carrying part. On the other hand, good lubrication can further prolong the service life of the power end of the fracturing pump and the lubricating oil.

[0004] Therefore, compared with conventional land fracturing, it is necessary to improve the reliability and lubrication efficiency of the power end lubrication system of the ocean fracturing pump according to the characteristics of ocean fracturing, and to add a monitoring system to realize linkage and remote monitoring with the central control system of the offshore platform. SUMMARY

[0040] Please see Figures 1-6 This invention provides a lubrication method for the power end of a marine fracturing pump, comprising the following steps:

[0041] S100: Obtain the lubricating oil output from the multi-pump, and distribute the flow of the lubricating oil through the proportional distribution valve to obtain the distributed lubricating oil;

[0042] S200: The distributed lubricating oil is processed by an independent filtration system and then delivered to the corresponding lubrication point;

[0043] S300: A sensor is installed at the lubrication point to collect lubrication status data in real time;

[0044] S400: The lubrication status data is transmitted to the monitoring system for analysis, processing, and fault warning.

[0045] In this embodiment, firstly, lubricating oil output from a multi-pump system is obtained, and after being processed by an independent filtration system, it is delivered to a proportional distribution valve. Subsequently, the lubricating oil is distributed according to its flow rate through the proportional distribution valve to obtain the distributed lubricating oil. Then, sensors are installed at the lubrication points to collect lubrication status data in real time. Finally, the lubrication status data is transmitted to a monitoring system for analysis, processing, and fault warning. By using multiple independent sub-lubrication systems to achieve on-demand oil supply, combined with precise flow distribution and real-time monitoring, this method solves the problems of uncontrollable oil distribution caused by a single pump supply, low precision and efficiency of a single filtration system, uneven flow distribution at lubrication points, and lack of monitoring in the prior art.

[0046] Furthermore, in the step of obtaining the lubricating oil output from the multi-pump and distributing the flow of the lubricating oil through a proportional distribution valve to obtain the distributed lubricating oil, the specific process is as follows:

[0047] S101: Set the flow distribution ratio of the proportional distribution valve according to the lubrication requirements of each lubrication point;

[0048] S102: The lubricating oil output from the multi-pump enters the proportional distribution valve and is forcibly distributed according to the flow distribution ratio to obtain the target flow rate of lubricating oil at each lubrication point.

[0049] In this embodiment, a proportional distribution valve is installed at the lubrication pump outlet of each sub-lubrication system, enabling forced distribution of lubricating oil according to a set ratio. For example, in a crankshaft sub-lubrication system, which includes multiple crankshaft bearing and bushing lubrication points, the flow rate ratio corresponding to each point is calculated based on the lubricating oil demand. These ratios are then input into the proportional distribution valve for setting. The lubricating oil pressure output from the multi-unit pump is stable. After entering the proportional distribution valve, the valve's precision structure distributes the lubricating oil to each outlet according to the set ratio. Each outlet corresponds to an oil passage for a lubrication point, thereby ensuring that each lubrication point receives the required lubricating oil flow rate.

[0050] Furthermore, in the step of setting the flow distribution ratio of the proportional distribution valve according to the lubrication requirements of each lubrication point, the specific process is as follows:

[0051] S1011: Obtain the operating parameters of each lubrication point in the crankshaft assembly, crosshead gearbox assembly, and gearbox assembly;

[0052] S1012: Based on the operating parameters, determine the required amount of lubricating oil at each lubrication point;

[0053] S1013: Calculate and set the flow distribution ratio of the proportional distribution valve based on the required amount of lubricating oil.

[0054] In this embodiment, parameters collected for lubrication points such as crankshaft bearings and crankshaft bushings include rotational speed, radial / axial load, friction pair temperature, and lubricating oil inlet pressure. For example, when the crankshaft rotates at high speed, the bearing load changes with operating conditions, requiring the use of pressure sensors (such as...) Figure 1 The first pressure sensor group (P1) monitors the oil film pressure in real time, and the temperature sensors (T1, T2) monitor the bearing and bushing temperatures. For points such as the upper / lower tracks and the small end bearing of the crosshead connecting rod, parameters are collected including reciprocating speed, contact pressure, track temperature, and lubricating oil flow fluctuations. For example, the crosshead track generates alternating loads during reciprocating motion, requiring the second pressure sensor group (P2) to monitor the track lubricating oil pressure and the T3 temperature sensor group to monitor the track friction surface temperature. For points such as the gear meshing area and bearings, parameters are collected including gear speed, meshing load, bearing vibration amplitude, and lubricating oil contamination. For example, the gearbox bearing requires the third pressure sensor group (P3) to monitor oil pressure and the oil quality sensor to monitor the content of wear particles in the oil. According to fluid lubrication theory (such as the Reynolds equation), the greater the load, the greater the required oil film thickness, corresponding to an increase in lubricating oil demand. For example, the crankshaft bearing load F and the required lubricating oil flow rate Q satisfy the empirical formula: Q = k × F × n (k is a coefficient, n is the rotational speed).

[0055] Furthermore, in the step of processing the distributed lubricating oil through an independent filtration system and then delivering it to the corresponding lubrication point, the specific process is as follows:

[0056] S201: The independent filtration system includes a second fine filter corresponding to each sub-lubrication system;

[0057] S202: Set the filtration parameters of the second fine filter according to the filtration accuracy requirements of each sub-lubrication system;

[0058] S203: After being filtered by the second fine filter, the distributed lubricating oil is delivered to the corresponding lubrication points through an independent lubrication pipeline.

[0059] In this embodiment, the filtration parameters of the second fine filter are set according to the filtration accuracy requirements of each sub-lubrication system. Different component assemblies have different requirements for the cleanliness of the lubricating oil. For example, the gearbox assembly requires higher filtration accuracy due to the large amount of metal debris generated by gear meshing; while the crosshead box assembly has relatively lower filtration accuracy requirements. Therefore, different filtration accuracies are set for the second fine filters of each sub-lubrication system. For example, the second fine filter of the gearbox lubrication system uses a high-precision filter element with a filtration accuracy of 5μm, while the second fine filter of the crosshead box lubrication system has a filtration accuracy of 10μm. The distributed lubricating oil first enters the corresponding second fine filter to remove impurities and contaminants from the oil, and then is delivered to each lubrication point through specially designed independent lubrication pipelines. The independent lubrication pipelines are optimized according to the location and layout of each lubrication point to ensure that the lubricating oil can reach each point smoothly and evenly, avoiding uneven flow caused by pipeline routing and distance.

[0060] Furthermore, in the step of installing sensors at the lubrication points to collect lubrication status data in real time, the specific process is as follows:

[0061] S301: A first pressure sensor group is installed in the crankshaft lubrication oil circuit to collect oil pressure data at the crankshaft lubrication points;

[0062] S302: A second pressure sensor group is installed in the lubrication oil circuit of the crosshead slide to collect oil pressure data at the lubrication points of the crosshead slide;

[0063] S303: A third pressure sensor group is installed in the gearbox lubrication circuit to collect oil pressure data at the gearbox lubrication points;

[0064] S304: Temperature sensor groups are installed in crankshaft bearings, bearings, crosshead slides, gearbox bearings, etc., to collect temperature data of the corresponding parts.

[0065] In this embodiment, a first pressure sensor group (P1) is installed in the crankshaft lubrication circuit to collect oil pressure data at the crankshaft lubrication points. The first pressure sensor group is distributed at the lubrication oil inlets of each crankshaft bearing and bushing, monitoring the lubrication oil pressure at these points in real time to ensure the pressure is within the normal operating range. If the pressure is too low, it may indicate insufficient lubrication or oil circuit blockage, requiring timely troubleshooting. A second pressure sensor group (P2) is installed in the crosshead slide lubrication circuit to collect oil pressure data at the crosshead slide lubrication points. The second pressure sensor group is installed in the upper and lower slide lubrication channels of the crosshead assembly to monitor the lubrication oil pressure at the slide parts, ensuring sufficient lubrication during the reciprocating motion of the slide. A third pressure sensor group (P3) is installed in the gearbox lubrication circuit to collect oil pressure data at the gearbox lubrication points. The third pressure sensor group is arranged in the gear and bearing lubrication circuits of the gearbox to monitor the lubrication oil pressure at the gear meshing and bearing rotation parts, ensuring the normal operation of the gearbox. Temperature sensor arrays are installed on crankshaft bearings, bearings, crosshead slides, gearbox bearings, and other components to collect temperature data at the corresponding locations. For example, the first oil temperature sensor array (T1) is installed on the crankshaft bearing to monitor its temperature in real time; the second oil temperature sensor array (T2) is installed at the crankshaft bearing to monitor its temperature; the third oil temperature sensor array (T3) is installed on the crosshead slide to monitor its temperature; and the fourth oil temperature sensor array (T4) is installed at the gearbox bearing to monitor its temperature. Temperature data directly reflects the lubrication and operating conditions of the components. An abnormally high temperature may indicate poor lubrication or accelerated wear of the components.

[0066] Furthermore, in the step of transmitting the lubrication status data to the monitoring system for analysis, processing, and fault early warning, the specific process is as follows:

[0067] S401: Transmits oil pressure and temperature data to the monitoring system;

[0068] S402: The monitoring system performs real-time analysis on the data to determine whether it exceeds a preset threshold;

[0069] S403: If the preset threshold is exceeded, a fault warning message is generated and sent to the central control system.

[0070] In this embodiment, lubrication status data such as oil pressure, temperature, and oil quality parameters are transmitted to the monitoring system via a data transmission module. The data transmission module employs a reliable communication protocol to ensure real-time and accurate data transmission, preventing data loss or delay. The monitoring system has a built-in preset threshold database, setting normal operating ranges and warning thresholds for each monitoring parameter based on the fracturing pump's design parameters and operational experience. When the data collected by the temperature sensor exceeds the rated value, an early warning is triggered. Once the monitoring system detects data exceeding the threshold, it immediately generates a warning message containing information such as fault type, location, and severity, and transmits it to the central control system on the offshore platform via the network. Upon receiving the warning message, the central control system can promptly notify operators to inspect and handle the situation, preventing further escalation of the fault.

[0071] Corresponding to the foregoing embodiments of the power-end lubrication method for marine fracturing pumps, this application also provides embodiments of a power-end lubrication system for marine fracturing pumps.

Figure 7 The system may include: an oil distribution module 501, a filtration and conveying module 502, a data acquisition module 503, and a monitoring and early warning module 504, wherein:

[0073] The oil distribution module 501 is used to acquire learning material data, dynamically adjust the encryption strength according to different characteristics, and encrypt the learning resource data.

[0074] The filter delivery module 502 is used to deliver the distributed lubricating oil to the corresponding lubrication point after it has been processed by an independent filtration system.

[0075] The data acquisition module 503 is used to set sensors at lubrication points and collect lubrication status data in real time.

[0076] The monitoring and early warning module 504 is used to transmit lubrication status data to the monitoring system for analysis, processing, and fault warning.

[0077] In this embodiment, the oil distribution module 501 achieves precise distribution of lubricating oil through a multi-pump and proportional distribution valve; the filtration and delivery module 502 ensures the cleanliness and delivery effect of the lubricating oil by utilizing an independent second fine filter and lubrication pipeline; the data acquisition module 503 comprehensively collects lubrication status data through multiple sensors; the monitoring and early warning module 504 analyzes and processes the data to achieve fault early warning and predictive maintenance; and the on-demand oil supply is achieved through multiple independent sub-lubrication systems.
