Description

Intelligent online lubricating device applied to industrial equipment bearing

Technical Field

The utility model relates to the technical field of lubricating systems, in particular to an intelligent online lubricating device applied to industrial equipment bearings.

Background

For the thermoelectric, metallurgical, mining, petrochemical industries, a large amount of mechanical equipment is required in the production process. The lubrication controller system is used for realizing the lubrication of the bearing of the equipment, thereby realizing the normal operation of the equipment, prolonging the service life of the equipment and reducing the energy consumption. The existing lubricating system part adopts a single-line progressive centralized lubricating system and comprises a lubricating pump, an oil supply pipeline, branch pipelines, all-level progressive distributors and an electric control part. The pump station outputs lubricating grease, and the one-way oil output is changed into multi-way oil transportation through the first-level distributor. The multi-path oil is divided into more branch oil paths by the second-stage distributor, and a third-stage distributor can be added according to the requirement. Thus, the oil is dispersedly supplied to the oil supply part in a progressive mode, and a single-line progressive oil way is formed. And after the lubrication is finished, timing by the system according to the oil feeding time arranged in the electric cabinet, and carrying out the next oil feeding action after the timing time. The single-line progressive centralized lubrication system has a serious defect that when one lubrication point in the system is blocked, all the lubrication points which are connected in series cannot be lubricated, and the fault point is difficult to find and maintain in time. Therefore, the risk of such lubrication systems is high. And part of the double-line centralized lubricating system comprises an electric lubricating pump, an electric/electromagnetic reversing valve, a double-line oil feeder, a dry oil filter, a differential pressure switch/pressure control valve, an electric control cabinet, two main oil supply pipelines and a plurality of branch oil supply pipelines. The lubricating pump outputs lubricating grease, the grease is conveyed to the double-line distributor through a main pipeline, and the grease is quantitatively distributed to all lubricating points through the double-line distributor. The tail end of the oil supply main pipeline is provided with a differential pressure switch/a pressure control valve (one is arranged on each of the two main pipelines), when the pressure of the tail end reaches a set value, a signal is sent to the electric control cabinet, the reversing valve is reversed, lubricating grease output by the lubricating pump is conveyed to the double-line distributor through the other oil supply pipeline, and is quantitatively distributed to each lubricating point through the double-line distributor. Thus, a complete oil feeding process is completed. And a time relay in the electric control cabinet times according to the set oil supply time, and when the time is up, the system starts the next oil supply action. In the double-line centralized lubrication system, all the lubrication points are in a grouped parallel connection relationship, and the defect that one point is blocked and multiple points cannot be lubricated in a single-line system is overcome. However, when the differential pressure between two lines is reduced due to some leakage, the whole lubrication system may be broken down because the main pipe is not reversed; when a lubrication point in the system has a blockage fault, the blockage fault is difficult to find in time, and the specific position of the fault is difficult to find; there is a large difference between the actual oil supply amount and the set value at each lubrication point, and it is difficult to ensure the supply amount of the lubricating oil reliably. The specific situation of double-line centralized lubrication oil supply is unclear, and in actual application, in order to ensure the lubrication requirement of equipment, an excessive oil supply mode is often adopted, so that the lubricating grease is seriously wasted.

Further, an air switch, a motor protection switch, a contactor, an intermediate relay, a switching power supply 14, a button and an indicator lamp are arranged in the main control box.

Further, the device also comprises an upper computer 1, wherein the upper computer 1 is electrically connected with the main control box 2.

Further, one end of the lubricating pump 4 is provided with a main loop contactor 12 of the lubricating pump 4, one end of the main loop contactor 12 of the lubricating pump 4 is provided with a second switch 10, one end of the oiling pump 5 is provided with a main loop contactor 13 of the oiling pump 5, one end of the main loop contactor 13 of the oiling pump 5 is provided with a third switch 11, and the second switch 10 and the third switch 11 are connected in parallel and then connected in series with a first switch 9.

Further, the PLC controller 16 is electrically connected to the signal collector 18, and the signal collector 18 is electrically connected to the pressure transmitter 3, the temperature vibration sensor 8, the hall proximity switch 17, and the electromagnetic valve 19.

The PLC 16 realizes the logic control of the whole system, including the start and stop of the lubricating pump 4 and the oiling pump 5, the on-line monitoring of the bearing state, the fault alarm, the data storage and the like. The touch screen 15 displays the lubrication state of the device in real time and can change the lubrication parameters through the touch screen 15. The signal collector 18 collects the pressure value of the branch pipeline and the temperature value vibration value of the bearing at the lubrication point and transmits the values to the PLC 16. The PLC controller 16 and the signal collector 18 communicate to collect the state of the lubrication point and control the lubrication. The pressure transmitter 3 monitors the pressure of the pipeline, thereby judging faults such as blockage, leakage and the like of the pipeline. The temperature vibration sensor 8 monitors the temperature and vibration state of the bearing in real time.

In the present embodiment, the first switch 9 is used as a main power switch of the system, the second switch 10 and the third switch 11 are respectively used as protection switches of the lubrication pump 4 and the gasoline pump 5, the first switch 9 is connected with a lubrication pump main circuit contactor 12, the second switch 10 is connected with a gasoline pump main circuit contactor 13, and the switch power supply 14 provides a direct current 24V power supply for the system. The PLC controller 16, which is the core of the system, communicates with the touch screen 15 via ethernet. The pressure transmitter 3 collects the oil supply pressure of the main pipe and transmits the oil supply pressure to the PLC controller 16, so that the PLC controller 16 can judge the pressure of the system. The PLC controller 16 and the signal collector 18 adopt RS485 serial port communication, the signal collector 18 transmits collected temperature, vibration, pressure, the state of the Hall proximity switch 17 and the like to the PLC controller 16, and the PLC controller 16 transmits a control signal of the electromagnetic valve 19 to the signal collector 18 to execute corresponding actions. Specifically, after the lubricating pump 4 is started, the pressure of the main pipeline rises, when the pressure reaches a set pressure value, the electromagnetic valve 19 corresponding to the oil injection point is electrified, at the moment, the grease pushes the plunger in the valve block to act and start timing, and at the moment, the pipeline pressure is reduced; when the plunger moves to the limit position, the Hall proximity switch 17 in the valve block counts the time and stops after monitoring the position of the plunger, and meanwhile, the program records the time; then the pressure of the pipeline rises, when the pressure reaches a set pressure value, the electromagnetic valve 19 is powered off, the plunger moves reversely and starts timing, and when the action time of the plunger is reached, one-time oil injection action is finished.

Further, the ways of fat supplement can be divided into automatic fat supplement and manual fat supplement.

In the manual grease filling method, the amount of grease filling for each oil injection point and whether the solenoid valve 19 for each oil injection point is activated are individually set.

In the automatic fat-supplementing mode, three different fat-supplementing modes are further divided

a) Timing and quantifying mode:

in this mode, the grease supply amount and the grease supply pause time can be set individually for each oil injection point. After the setting is completed, the system can automatically perform point-by-point fat supplement according to the fat supplement amount of each point and the intermittent time. The system can monitor the intermittent time of all oil injection points in real time, when the intermittent time of any oil injection point is up, the lubricating pump 4 is started to supplement grease to the point, after the grease supplement is finished, the lubricating pump 4 can operate in a delayed mode for 5s, if the intermittent time of other oil injection points is up in 5s, the lubricating pump 4 stops operating, and the system continues to monitor the intermittent time of all oil injection points.

In the intermittent grease supplementing process when the lubricating pump 4 stops, the oiling point number can be manually input, and the system can immediately supplement grease for the point according to the set grease supplementing amount, regardless of whether the intermittent time is timed to be ended or not. After the completion of the fat supplement, the intermittent time of the point is counted again according to the set intermittent time.

b) Vibration control mode:

in the mode, the grease filling of the oil filling point is not limited by the grease filling interval time, the vibration state of the bearing at the oil filling point is monitored in real time, and when the monitored vibration value (the vibration value in any direction of three axial directions X/Y/Z) exceeds a set vibration threshold value, the lubricating pump 4 is started to fill the grease at the oil filling point according to the set grease filling amount.

Like the timing and quantitative grease filling, the manual grease filling can be carried out on any oil injection point in the intermittent process of stopping the lubricating pump 4

c) And (3) a compound fat supplementing mode:

the mode is the combination of the first two modes; on the basis of timing and quantitative fat supplement, vibration control fat supplement is added; the priority of the timing and quantitative fat supplement is higher than that of the vibration control fat supplement.

It should be noted that under the condition that the bearing of the device to be lubricated does not work, some specific oil injection points do not need oil injection; at this time, the touch screen 15 may be provided with a closing solenoid valve 19 to close the oil filling point. After the electromagnetic valve 19 is closed, the subsequent point-by-point oil feeding process automatically skips the oil filling point, and grease is added to other oil filling points.

Further, the operation of the gasoline pump 5 is divided into a manual mode and an automatic mode.

In the manual mode, the starting and stopping of the gasoline pump 5 and the starting time can be controlled manually. When the start button is pressed, the gasoline pump 5 is started, and when the stop button is pressed, the gasoline pump 5 is stopped.

In an automatic mode, the start and stop of the oiling pump 5 are controlled by a liquid level switch of the lubricating oil tank, and when the lubricating oil tank reaches a low liquid level, the oiling pump 5 is automatically started; when the low liquid level signal disappears, the gasoline pump 5 stops running.

In this embodiment, the system further comprises a fault alarm device, wherein the fault alarm device comprises: overload of the lubricating pump 4, overload of the gasoline pump 5, low liquid level of the oil tank, pipeline blockage, pipeline leakage, blockage of the electromagnetic valve 19, disconnection of the pressure transmitter 3, temperature abnormality of a bearing at a lubricating point, vibration abnormality of the bearing at the lubricating point and disconnection of a temperature vibration sensor.

The master control system and the control boxes of the substations are in communication connection through serial ports, each substation control box can be provided with a plurality of oil injection points, and different numbers of substation control boxes can be configured according to actual needs to meet use requirements. The PLC 16 and the touch screen 15 communicate through Ethernet to monitor the running state of the system in real time; the parameters of the system can also be set via the touch screen 15. And a temperature vibration sensor 8 is configured to monitor the running state of the bearing at the oil injection point in real time, and the automatic grease supplementing function can be realized according to signals fed back by the sensor. And the pressure transmitter 3 is configured, so that the faults such as leakage and blockage of the pipeline can be judged according to the state of the pressure transmitter 3. The data storage system stores the detected data in real time.
