Description

Technical Field

[0001] This invention relates to the field of long-distance oil and gas pipeline transportation, specifically to an oil pump lubricating oil photoresist detection device, a magnetic detection device, and an online monitoring system. Background Technology

[0002] Long-distance oil pipelines typically utilize pressure boosting equipment, often employing large centrifugal oil pumps, which are the core power equipment for these pipelines. Currently, the lubrication method for these pump units is dispersed splash lubrication, a relatively simple method limited to enclosed systems. Oil quality monitoring, based on the pump's operating mode and structural characteristics, usually relies on manual observation through the oil tank's sight glass. The automatic protection system for the bearing housing lubrication system only provides oil temperature protection, relying on the decrease in lubrication performance due to deteriorating lubricating oil quality or the temperature rise caused by bearing aging or wear to trigger alarms and protection. However, the diverse natural environments of long-distance pipelines and the complex installation environments of oil pumps make using abnormal bearing housing temperature rises to trigger alarms unreliable criteria for lubrication system judgment.

[0003] With the continuous advancement of pipeline technology, the number of personnel at oil transfer stations has decreased significantly. The patrol duties of station personnel have been greatly reduced, making it difficult to implement intensive manual inspections to confirm oil quality. While there are many commercially available, mature oil quality testing instruments are readily available. However, due to the characteristics of decentralized splash lubrication, each oil pump unit typically has 2 or 4 lubrication points. Stations, with their functions and scale, typically house 3 to 20 large oil pumps. Splash lubrication is a closed mechanism with a compact structure and limited space, making it difficult to install testing instruments at every point for real-time monitoring.

[0004] The bearing housing and mechanical seal leakage sludge box of the oil pump are integrated. If the mechanical seal leakage pipeline becomes blocked, sludge will enter the lubricating oil tank, causing lubricating oil contamination and ultimately bearing damage. The lubrication system of the oil pump unit is a closed system, with a typical lubricating oil tank capacity of approximately 5 to 15 liters. Once bearing wear or sludge contamination occurs, the lubricating oil's performance will rapidly decline, leading to a vicious cycle of further bearing wear. In emergency situations such as sludge contamination and bearing damage, if left in extremely cold environments and waiting for the bearing temperature to rise to the alarm level, the bearing may already be severely damaged, often resulting in pump shaft damage and major pump overhaul.

[0044] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0045] Example 1

[0046] like Figure 1 and Figure 2 As shown, the oil pump lubricating oil light obstruction detection device 9 of this embodiment includes an oil storage device 1, a light source transmitting device 2, and a light source receiving device 3. The oil storage device 1 is provided with a first light-transmitting sheet 11 and a second light-transmitting sheet 12, which are arranged in parallel relative to each other.

The oil storage device 1 is provided with an oil inlet 192 and an oil outlet 193.

[0047] like Figure 1 As shown, the oil storage device 1 in this embodiment has an open structure at both ends. A first end cap 13 and a second end cap 14 are detachably installed at the open structures at both ends of the oil storage device 1. The first light-transmitting sheet 11 is sealed and installed inside the first end cap 13 by a sealing ring 15, and the second light-transmitting sheet 12 is sealed and installed inside the second end cap 14 by a sealing ring 15. The light source transmitting device 2 is installed on the first end cap 13, and the light source receiving device 3 is installed on the second end cap 14, which facilitates the installation and removal of the first and second light-transmitting sheets, as well as the installation and removal of the light source transmitting device and the light source receiving device.

[0048] like Figure 1 As shown, in this embodiment, the first end cap 13 has a first assembly hole, and the second end cap 14 has a second assembly hole. A first assembly pipe 16 is provided at the first assembly hole, and a second assembly pipe 17 is provided at the second assembly hole. The light source transmitting device 2 is installed inside the first assembly pipe 16, and the light source receiving device 3 is installed inside the second assembly pipe 17. Installing the light source receiving device 3 and the light source transmitting device 2 inside the assembly pipes can protect the light source receiving device and the light source transmitting device.

[0049] like Figure 1 As shown, the light source receiving device 3 in this embodiment includes a photoresistor, and the light source transmitting device 2 includes a light-emitting diode.

[0050] The light resistance of normal lubricating oil, moderately contaminated lubricating oil, and heavily contaminated lubricating oil was measured using an oil pump lubricating oil light resistance detection device. The light resistance value of normal lubricating oil was 84U, that of moderately contaminated lubricating oil was 45U, and that of heavily contaminated lubricating oil was 17U.

[0051] The oil pump lubricating oil light obscuration detection device in this embodiment, by setting up a light source receiving device and a light source transmitting device, together with a light-transmitting sheet, can determine the turbidity of the lubricating oil through light obscuration detection, and protect against the early stage of lubricating oil contamination incidents to prevent the incidents from escalating. At the same time, it fills the blind spots of the oil pump unit oil station inspection robot system.

[0052] Example 2

[0053] like Figure 3 and Figure 4As shown, the oil pump lubricating oil magnetic blocking detection device 91 of this embodiment includes the oil pump lubricating oil light obstruction detection device 9 of the above embodiment 1. A first magnet 18 is provided on the inner wall of the oil storage chamber. The first magnet 18 is arranged adjacent to the first light-transmitting sheet 11. A second magnet 19 is provided on the oil storage device 1 outside the first light-transmitting sheet 11. The second magnet 19 is arranged on the periphery of the light transmission path of the light source transmitting device 2.

[0054] like Figure 3 As shown, the inner wall of the oil storage chamber of the oil storage device 1 in this embodiment is also provided with a protrusion 10. The protrusion 10 is located inside the first light-transmitting sheet 11. The protrusion 10 has an oil outlet 193 that passes through the oil storage chamber. The protrusion 10 is provided with a third magnet 190. The third magnet 190 is arranged adjacent to the oil outlet 193. The third magnet 190 and the second magnet 19 are arranged in a corresponding manner along the light path transmission direction parallel to the light source transmitting device 2. The first magnet 18 is arranged on the inner wall of the oil storage chamber opposite to the protrusion 10. It can attract iron filings at the oil outlet to block the light.

[0055] like Figure 3 As shown, the oil storage device 1 in this embodiment is also provided with a bypass port, and a bypass pipe 191 is connected to the bypass port. By providing the bypass port and bypass pipe, oil can be discharged through the bypass port when the oil outlet is blocked.

[0056] The decline in lubricating oil quality in oil pump units is usually due to bearing wear and contamination of the sludge system. Bearing wear produces iron or copper shavings. Iron shavings are attracted by the magnetic force in the flow channel. The attracted iron shavings block the light path, causing the photoresistor to reach its maximum resistance and the voltage to drop significantly, triggering an alarm from the control system.

[0057] The oil pump lubricating oil magnetic blocking detection device of this embodiment can use a first magnet and a second magnet to attract metal debris in the lubricating oil to block light, thereby determining the severity of metal debris in the lubricating oil, and can also play a self-cleaning role of the system.

[0058] Example 3

[0059] like Figure 5 and Figure 6As shown, the online monitoring system for lubricating oil in this embodiment is used for online monitoring of lubricating oil in bearing housing 4, which contains bearing 44. It includes the lubricating oil light resistance detection device 9 of Embodiment 1 and / or the lubricating oil magnetic blocking detection device 91 of Embodiment 2, and also includes an oil pump 53, a filter 51, a pressure sensor 52, and a controller 8. The bearing housing 4 has an oil filler port 41 at the top and an oil drain port 42 at the bottom. A first monitoring pipeline 5 connects the oil filler port 41 and the oil drain port 42. The first monitoring pipeline 5 is equipped with an oil pump 53, a filter 51, a pressure sensor 52, and the lubricating oil light resistance detection device 9 and / or the lubricating oil magnetic blocking detection device 91. The filter 51 is located adjacent to the oil filler port 41, and the oil pump 53 is located adjacent to the oil drain port 42. The pressure sensor 52, the lubricating oil light resistance detection device 9 and / or the lubricating oil magnetic blocking detection device 91 are located between the filter 51 and the oil pump 53.

[0060] The oil pump 53, filter 51, pressure sensor 52, oil pump lubricating oil light obscuration detection device 9 or / and oil pump lubricating oil magnetic blocking detection device 91 are electrically connected to the controller 8 through the controller terminal 81. The controller 8 is also electrically connected to an alarm device and a human-machine interface.

[0061] The oil pump lubricating oil light resistance detection device 9 and / or the oil pump lubricating oil magnetic blocking detection device 91 are used to detect the light resistance value of the first monitoring pipeline 5 and send it to the controller 8. The controller 8 is used to control the alarm device and / or the oil pump 53 to start and stop according to the light resistance value. The alarm device can be an audible and visual alarm. Specifically, the oil pump lubricating oil light resistance detection device 9 detects a first light resistance value, and the oil pump lubricating oil magnetic blocking detection device 91 detects a second light resistance value. The controller 8 is used to control the oil pump 53 to start and stop according to the second light resistance value, and to control the alarm device to perform an audible and visual alarm according to the first and second light resistance values. Since the first and second light resistance values ​​are different, segmented alarms can be implemented. When the first light resistance value reaches a first preset value, the alarm device is controlled to perform an audible and visual alarm; when the second light resistance value reaches a second preset value A, the alarm device is controlled to perform an audible and visual alarm; when the second light resistance value reaches a second preset value B, the controller 8 controls the oil pump to stop running, thus providing oil pump protection.

[0062] The pressure sensor 52 is used to detect the pressure value of the first monitoring pipeline 5 and send it to the controller 8. The controller 8 is used to send the pressure value, the first photoresist value and the second photoresist value to the human-machine interface for display.

[0063] like Figure 5As shown, in this embodiment, a manual refueling pipeline is also connected to the refueling port 41, and a manual refueling port 43 is connected to the manual refueling pipeline. A first valve 7 is provided on the manual refueling pipeline, and the opening and closing of the pipeline is controlled by the first valve 7.

[0064] like Figure 5 As shown, in this embodiment, a second monitoring pipeline 6 is also connected between the oil filling port 41 and the oil drain port 42. A liquid level sensor 61 is provided on the second monitoring pipeline 6. The liquid level sensor 61 is electrically connected to the controller. The liquid level sensor 61 is used to obtain the liquid level value in the bearing housing 4 and send it to the controller. The controller is used to send the liquid level value to the human-machine interface for display, so as to monitor the liquid level in the bearing housing 4.

[0065] Specifically, such as Figure 5 As shown, in this embodiment, the first monitoring pipeline 5 is equipped with a second valve 71, which is located between the oil drain port 42 and the oil pump 53. An oil drain pipeline is also connected between the second valve 71 and the oil pump 53, and a third valve 72 is installed on the oil drain pipeline. When refueling, the second valve can be closed and the third valve opened, allowing the oil pump 53 to refuel. When circulating and testing the oil quality, the second valve can be opened and the third valve closed. When refueling manually, both the second and third valves can be closed, and the first valve can be opened.

[0066] The controller in this embodiment is also connected to a terminal device via a communication module. The controller is used to send the received pressure value, photoresistance value, and liquid level value to the terminal device via the communication module.

[0067] The controller employs a single-chip microcomputer control system comprised of an analog-to-digital converter module, a control system, and a communication module. It performs real-time analysis of the detected signals through the analog-to-digital converter and software computation and analysis. A human-machine interface and audible and visual alarm devices are installed on-site. The communication module transmits detection data or alarm signals to terminal equipment or mobile phones in the station control room via 2.4G wireless communication, serial port, GSM, etc., depending on the actual on-site conditions. On-duty personnel and production operation technicians can remotely receive alarm information and check the status.

[0068] The bearing housing 4 also has a viewing window for observing the liquid level. The online monitoring system for lubricating oil in the oil pump also functions as a lubricating oil replacement and tank cleaning function for the oil pump unit. Currently, adding lubricating oil to the oil pump unit requires manual oil can addition, which requires two people working together. One person adds oil and monitors the oil level until it reaches halfway up the viewing window of the tank, then stops adding oil, and finally replenishes it using a constant level oil cup. This system, using a liquid level monitoring module in conjunction with a circulating oil pump, allows a single person to independently complete the lubricating oil replacement work, reducing maintenance time and workload. The online lubricating oil monitoring system is also a lubricating oil cleaning system. Its filter is a multi-layer filter with a mesh size of 300 to 500 mesh, used to filter particles larger than 30μm. In the lubricating oil tank cleaning operation, this system can be used for online cleaning. The magnet in the oil pump lubricating oil magnetic blocking detection device 91 can effectively attract tiny iron filings. The purchased experimental iron powder is 10 to 40 microns in size. In the experiment, the oil pump lubricating oil magnetic blocking detection device 91 can quickly remove iron filings from the lubricating oil.

[0069] The decline in lubricating oil quality in oil pump units is usually due to bearing wear and contamination of the sludge system. Bearing wear produces iron or copper filings. Iron filings are magnetically attracted within the flow channel, blocking the light path. This causes the photoresistor's resistance to reach its maximum value, resulting in a significant voltage drop and triggering an alarm in the control system. Larger iron filings contaminate the lubricating oil, clogging the filter and causing an increase in inlet pressure. Pressure monitoring is used to determine oil quality changes. Sludge contamination of the lubricating oil leads to a significant change in its permeability. The LED, after being blocked by the lubricating oil, works in conjunction with the photoresistor to monitor oil quality by changing the resistance value based on the oil permeability. An online monitoring system can be equipped with multiple alarms to monitor the lubricating oil quality online. The oil pump lubricating oil magnetic blocking detection device 91 has only one alarm value, used to detect the light blocking caused by iron filings. The alarm value of the oil pump lubricating oil magnetic blocking detection device 91 is much higher than that of the oil pump lubricating oil photoresistance detection device 9. Even slight bearing wear can cause the lubricating oil to become cloudy, in which case the oil pump lubricating oil magnetic blocking detection device 91 will not send an alarm. If the oil quality is extremely poor, and the lubricating oil is so black that it completely blocks light, both modules will alarm simultaneously. Under suitable conditions, this can be used for shutdown protection of the oil pump unit.

[0070] Among these, filter clogging monitoring and liquid level monitoring are mature monitoring technologies with numerous implementation methods, none of which have been experimentally tested. In daily operation, filters serve as a means of oil purification. When impurities clog the filters, significant pressure changes occur in the system. The online monitoring system for lubricating oil in the oil pump utilizes this fault characteristic as a monitoring method to track changes in oil quality; the more severe the filter clogging, the worse the lubricating oil quality. The light obstruction method, through simulation experiments, uses the color change of the lubricating oil to block light. A significant change in the resistance of the photoresistor is observed, and the controller judges the oil quality by monitoring the voltage and determining the color change. The magnetic blocking detection device for oil pump lubricating oil uses a magnetic field to attract iron filings around a magnet. Magnets placed in the light channel attract iron filings from bearing wear. As the light channel aperture becomes smaller, the attracted iron filings gradually fill the channel, blocking light and causing the photoresistor to reach its maximum value, thus indicating excessive iron filings in the lubricating oil.

[0071] This embodiment of the online monitoring system for oil pump lubricating oil enables automatic monitoring of the lubricating oil quality in long-distance pipeline oil pumps, filling a gap in the monitoring of the operational status of core components of the oil pump unit. Turbidity is determined by light obscuration detection, and the severity of metal debris in the lubricating oil is assessed using filter differential pressure and magnetic electrode adsorption methods. This avoids the uncertainty of manual inspection in determining oil quality standards, providing timely alarms when bearing wear metal filings or contaminated oil appear, protecting against escalation of lubricating oil contamination incidents in their early stages, and also compensating for the blind spots of the oil pump unit's inspection robot system at the oil transportation station.

[0072] This embodiment of the online monitoring system for lubricating oil in the oil pump utilizes various methods based on the operational characteristics and abnormal events of the lubrication system. Dielectric strength monitoring uses magnetic electrodes to attract tiny iron filings that block light, while copper filings are deposited to block light. Wear monitoring employs a filter clogging pressure monitoring method, and contamination monitoring uses a light obstruction method. The system infers changes in oil quality by analyzing malfunctions in on-site oil quality assurance facilities, making complex detection techniques readily apparent. The online monitoring system can perform qualitative analysis of the lubricating oil quality and also features automatic lubricating oil filling and a self-cleaning function.
