It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Referring to fig. 1, the present embodiment provides an intelligent warning and troubleshooting system for abnormal fault of a lubrication system of mechanical equipment, including: a monitoring device module 110, a control system module 120, and a remote terminal module 130. The monitoring device module 110 includes a moisture pre-warning and draining device 111, an emulsification pre-warning and draining device 112, an abrasion particle pre-warning and adsorption removing device 113, a foam pre-warning and adjusting device 114, a filter pressure difference pre-warning and pressure-releasing device 115, and a respirator failure pre-warning and replacing device 116. The control system module 120 is communicatively coupled to the monitoring device module 110 and is configured to control the monitoring device module 110. The remote terminal module 130 is communicatively connected to the control system module 120 and is configured to receive the early warning signal and/or the recommended action from the control system module 120.
It should be noted that, in other embodiments, the monitoring device module 110 may also include several of a moisture pre-warning and draining device 111, an emulsification pre-warning and draining device 112, an abrasion particle pre-warning and adsorption draining device 113, a foam pre-warning and adjusting device 114, a filter pressure difference pre-warning and pressure relief device 115, and a respirator failure pre-warning and replacing device 116, or may also include other intelligent monitoring devices.
Specifically, the moisture pre-warning and draining device 111 and the emulsification pre-warning and draining device 112 are both installed at the bottom of the oil tank of the lubrication system. If the water content in the lubricating system is too high, the lubricating performance of the lubricating oil is greatly reduced. Since water has a higher density than lubricating oil and lubricating oil generally has an oil-water separation capability, water is generally deposited at the bottom of the oil tank when the lubricating system is immersed in water. When the device detects that the water content at the bottom of the oil tank is too high, an early warning signal can be generated and sent; the device may automatically perform a draining operation upon receiving an instruction from the control system module 120.
For example, referring to fig. 2, the moisture pre-warning and draining device 111 includes a first container 101, a first solenoid valve 102, and a first moisture sensor 103, wherein the first container 101 is communicated with the bottom of the oil tank. The communication mode can be through threaded connection, and the bottom of first container 101 is provided with the outlet, and the outlet is provided with first solenoid valve 102, and first moisture sensor 103 sets up the top in first container 101, and first moisture sensor 103 and first solenoid valve 102 all are connected with control system module communication 120. The first container 101 is generally made of a double-layer transparent material, and has a small volume relative to the oil tank, the specific volume being determined by the type of oil used in the lubrication system and the working environment, and the main function of the first container is to store free water deposited in the oil tank. When the first moisture sensor 103 detects that the first container 101 is full of water, the outlet may be controlled to discharge water for a time set by the volume of the first container 101 and the flow rate at the outlet.
The lubricating properties of lubricating oils are also greatly reduced if the oil is emulsified by water in the lubricating system. When water is invaded into a lubricating system, and the lubricating oil is not separated from the water phase or can not be completely separated due to the characteristics of the lubricating oil or the consumption of an anti-emulsifying agent and the like, three layering phenomena of a free water layer, an oil-water emulsifying layer and a lubricating oil layer can occur at the bottom of the oil tank. When the device detects that there is the profit emulsification layer bottom the oil tank, produce and send early warning signal, the content of package oiliness emulsification layer in the early warning signal. The control system module 120 sends different instructions to the device according to the content of the emulsion layer. When the content of the oil-water emulsion layer is less, the oil-water emulsion layer can be directly removed after the free water is removed; when the content of the oil-water emulsion layer is high, the control system module 120 sends specific treatment measures to the display terminal, such as adding an anti-emulsifier. Of course, the oil tank may also be provided with an anti-emulsifier adding device in communication connection with the control system module 120, that is, the oil tank may be communicated with an anti-emulsifier adding pipeline, and the opening and closing of the pipeline is controlled by a valve, so that the automatic adding of the anti-emulsifier is controlled by the control system module.
For example, referring to fig. 3, the emulsification early warning and draining device 112 includes a second container 104, a second solenoid valve 105, a second moisture sensor 106, and a color sensor 107, the second container 104 is communicated with the bottom of the oil tank, a drain port is disposed at the bottom of the second container 104, the second solenoid valve 105 is disposed at the drain port, the second moisture sensor 106 is disposed above the second container 104, the color sensor 107 is disposed above the outside of the second container, and the second moisture sensor 106, the color sensor 107, and the second solenoid valve 105 are all in communication connection with the control system module. The second container is generally made of a double-layer transparent material, and has a small volume relative to the oil tank, the specific volume depends on the type of oil used in the lubrication system and the working environment, and the main function of the second container is to store the emulsified water deposited in the oil tank (when the free water and the emulsified water exist at the same time, the free water is deposited below the emulsified water due to the higher density). The second moisture sensor 106 is disposed above the second container 104, and when the second moisture sensor 106 detects that the container is full of water, the second moisture sensor can control the outlet to drain water, and the draining time is set by the container volume and the flow rate at the outlet. The color sensor 107 is disposed above the exterior of the second container 104, and detects the color of the liquid in the container, and combines with the second moisture sensor 106 to determine whether emulsified water is present.
The wear particle early warning and adsorption removal device 113 is arranged at the bottom of an oil tank of the lubricating system; the wear particle early warning and adsorption removal device 113 comprises a wear particle detection device and an adsorption removal device, the wear particle detection device is arranged at the bottom in the oil tank, the adsorption removal device is communicated with the bottom of the oil tank, and the wear particle detection device and the adsorption removal device are both in communication 120 connection with the control system module. If the wear particles are returned to the friction pair through the circulation line of the lubrication system, the wear of the friction pair of the mechanical equipment is further increased. As the friction pair of the lubricating system is lubricated badly in the running process, abrasion metal particles with different material types are inevitably generated, wherein most of the abrasion metal particles are steel abrasion particles, and the abrasion metal particles return to the oil tank through the oil return pipe and are deposited at the bottom of the oil tank. The steel wear particles are attracted to the devices at the bottom of the tank due to their ferromagnetic nature. When the device detects that the steel abrasion particles at the bottom of the oil tank are more, an early warning signal is generated and sent; the device may automatically perform wear particle removal operations upon receipt of instructions from the control system module 120.
For example, referring to fig. 4, the wear particle early warning and adsorption removing device includes a third container 108, a third solenoid valve 109 and an electromagnet sensor 117, the third container 108 is communicated with the bottom of the oil tank, a drain outlet is formed in the bottom of the third container 108, the drain outlet is provided with the third solenoid valve 109, the electromagnet sensor is arranged at the communication position of the third container 108 and the oil tank, and partially extends into the oil tank, the electromagnet sensor 117 can detect the content of the magnetic wear particles, and both the electromagnet sensor 117 and the third solenoid valve 109 are in communication connection with the control system module. When the sensor adsorbs the wear metal particles, the specific content of the magnetic wear particles can be detected, and the electromagnet sensor is controlled to be powered off when the adsorption amount is saturated, so that the adsorbed wear particles fall into the container. After the abrasion particles fall off and deposit, the electromagnetic valve at the outlet can be controlled to remove the abrasion particles. The waiting time for the magnetic particles to fall off until the solenoid valve is opened depends on the viscosity grade of the lubricating oil and the type of equipment. The solenoid valve open purge time is set by the container volume and the flow rate at the outlet.
The foam early warning and adjusting device 114 is arranged above the oil level of the oil tank; foam early warning and adjusting device include that foam detection device and antifoaming agent add the device, and foam detection device sets up the oil level top in the oil tank, and the antifoaming agent adds the device and is connected with oil tank upper portion, and foam detection device and antifoaming agent add the device and all with control system module communication connection. If the foam cannot be eliminated in the lubricating oil tank, the lubricating performance of the lubricating oil is greatly reduced. The lubricating oil in the lubricating system inevitably generates foam when flowing and colliding, and the foam is generally eliminated within a certain time. If the foam is generated too much or cannot be eliminated for a long time, the foam can float above the oil level of the oil tank. When the foam detection device detects that the foam content in the oil tank is higher, generating and sending an early warning signal; the antifoaming agent adding device can automatically perform the operation of adding the antifoaming agent after receiving the instruction of the control system.
The filter differential pressure early warning and pressure relief device 115 is arranged on two sides of the filter of the oil inlet pipeline of the lubricating system; the filter pressure difference early warning and pressure relief device comprises a pressure difference detection device and a pressure relief device, wherein the pressure difference detection device is used for detecting the pressure difference between two sides of the filter of the oil inlet pipeline, the pressure relief device is connected to the oil inlet pipeline, and the pressure difference detection device and the pressure relief device are both in communication connection with the control system module 120. If the pressure difference of the filter is too large, the flow of the lubricating oil in the circulating pipeline of the lubricating system is insufficient, and the lubrication of a friction pair of mechanical equipment is affected. As the mechanical equipment inevitably generates oil sludge and damaged particles in the operation process, and invades solid pollutant particulate matters such as dust, the pollutant holding capacity of the filter is easily fully loaded, and the pressure difference of the filter is overlarge. When the device detects that the pressure difference between the two sides of the filter is overlarge, an early warning signal can be generated and sent; the control system module 120 sends specific processing measures to the display terminal; if the pressure difference is very large and the oil supply amount is seriously insufficient to influence the normal lubrication of the friction pair of the mechanical equipment, the control system module 120 sends an instruction, and the device can automatically perform the pressure relief operation. For example, a pressure difference meter may be installed on both sides of the filter, a pressure difference calculation module may be provided, the pressure difference is calculated and determined, the warning signal is sent to the control system module 120 after the pressure difference exceeds a preset threshold, the control system module 120 may further send the measure to the remote terminal module 130, and the control system module 120 may control the pressure relief valve installed on the oil inlet pipeline to relieve the pressure, and replace the filter element of the filter in time, and the like.
The respirator failure early warning and replacing device 116 is arranged on a respirator or a breathing port outside the oil tank; the ventilator failure warning and replacement device 116 includes a ventilator failure detection device and a desiccant replacement device, both of which are communicatively coupled to the control system module 120. If the respirator fails, moisture and dust particles in the air can invade into the lubricating system, the lubricating performance of the lubricating oil can be greatly reduced, and the abrasion of a friction pair of mechanical equipment is further increased. When the respirator failure detection device detects that the respirator is failed, generating and sending an early warning signal; the desiccant replacement device may automatically replace the desiccant beads in the respirator upon receiving instructions from the control system module 120. For example, the respirator failure detection device may be a color sensor, and when the color sensor detects that the active desiccant particles inside the container are failed, the color sensor may first control the solenoid valve at the outlet to open to discharge the desiccant particles; after a period of time, the electromagnetic valve at the outlet is closed, and then the electromagnetic valve at the inlet is controlled to be opened to allow new desiccant particles to flow in, so that the functions of respirator failure early warning and automatic replacement are realized.
In this embodiment, the monitoring device module is configured to send signals in the lubrication system status signal library to the control system module. The lubrication system status signal library sent by the monitoring device module is shown in table 1:
table 1: lubricating system state signal library sent by monitoring device module
Further, referring to fig. 1 again, in the present embodiment, the control system module 120 includes an expert system 121 and an internet of things server 122, and the expert system 121 is configured to process the lubricating system abnormal state monitoring signal from the monitoring device module 110 and form an early warning signal to send to the remote terminal module 130. The expert system 121 is a software system, integrates related expert knowledge, and is written into the internet of things server 122 for subsequent fault diagnosis and fault removal. The internet of things server 122 is connected to each device in the monitoring device module 110, and is also connected to each display terminal in the remote terminal module 130.
After the control system module 120 receives the lubrication system abnormal state monitoring signal from the monitoring device module 110, the expert system 121 processes the state signal and then sends a control command to the monitoring device module 110. The control instruction library in the expert system 121 is shown in table 2. After receiving the command from the control system, the monitoring device module performs corresponding troubleshooting processing, and sends a status signal of the processing result back to the control system module 120.

Further, after the control system module 120 receives the lubricating system abnormal state monitoring signal and the processing result state signal from the monitoring device module 110, the expert system 121 also processes the lubricating system abnormal state monitoring signal and the processing result state signal, and forms an early warning signal to be sent to the remote terminal module 130, so as to remind the equipment operation and maintenance personnel of the background monitoring center in a sound alarm and screen display manner. The early warning and status signal library in the expert system 121 is shown in table 3.

The failure cause analysis and elimination recommended action sentence library in the expert system 121 is shown in table 4. After seeing the fault diagnosis and removal suggestions of the lubricating system, equipment operation and maintenance personnel of the background monitoring center can firstly know the faults of the lubricating system more comprehensively, secondly know the reasons of the faults of the lubricating system and thirdly carry out related fault troubleshooting and manual treatment according to the diagnosis suggestion measures.
