Description

Technical Field

[0001] This utility model relates to the field of lubrication system technology, and in particular to a flow monitoring device for lubrication systems. Background Technology

[0002] Paper machine lubrication systems typically employ several flow meters to monitor flow rate. When lubricant flow is insufficient or excessive, precise control of the flow rate at the corresponding lubrication points is necessary to ensure normal operation. However, current flow detection methods in paper machine lubrication systems have the following drawbacks: The commonly used flow meters only detect flow rate and cannot promptly share the data with a host computer for analysis. The system still relies heavily on manual readings by inspection personnel, who then manually transmit the data to the host computer for analysis. This current approach fails to detect flow anomalies immediately, hindering real-time and precise control of lubricant flow at each point. Furthermore, temperature variations in lubricant can lead to inaccurate flow rate readings, posing a risk of oil loss during daily operation. Therefore, a solution is urgently needed that can monitor numerous lubrication points in real-time and reliably transmit data to a host computer promptly. Utility Model Content

[0016] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0017] See Figure 1 and Figure 2 This utility model provides a flow monitoring device for a lubrication system, comprising: a bracket 1, a housing 2, a first oil inlet valve group 3, a second oil inlet valve group 4, a first flow meter module 5, a second flow meter module 6, and a monitoring module 7.

[0018] The enclosure 2 is mounted on the bracket 1, and the enclosure 2 is equipped with a door 8. Preferably, the door 8 is equipped with an electronic lock to prevent unauthorized personnel from operating or damaging the internal components of the enclosure, thus providing a safety protection function.

[0019] The first inlet valve assembly 3 and the second inlet valve assembly 4 are located at the upper and lower parts of the housing 2, respectively. The input ends of the first inlet valve assembly 3 and the second inlet valve assembly 4 are connected to the upper and lower parts of the inlet pipe, respectively. The inlet pipe is located outside the housing 2. Figure 2 The hollow arrow shown illustrates the lubricating oil inlet, with the lubricating oil entering from the inlet port 93 of the inlet pipe. The first inlet valve group 3 consists of multiple first valves, and the second inlet valve group 4 consists of at least one second valve. Each valve corresponds to a lubrication point in the lubrication system. The output end of the first inlet valve group 3 is connected to an outlet port 91, and the output end of the second inlet valve group 4 is connected to an outlet port 92. Both outlets extend to the outside of the housing 2.

[0020] Preferably, the total flow rate of the first inlet valve group 3 is greater than the total flow rate of the second inlet valve group 4. By setting up two inlet valve groups with different flow rates, the user can use only the first inlet valve group 3 or the second inlet valve group 4, or use both inlet valve groups at the same time to operate the lubrication system, according to the actual working needs.

[0021] The first flow meter module 5 is located at the output end of the first inlet valve group 3, and includes multiple rotor flow meters installed in a one-to-one correspondence with the first valve. The second flow meter module 6 is located at the output end of the second inlet valve group 4, and includes at least one rotor flow meter installed in a one-to-one correspondence with the second valve. The rotor flow meters are commercially available products, and they convert pressure difference into electrical signals to achieve flow detection. In this embodiment, as... Figure 1 As shown, the first flow meter module 5 is equipped with 14 rotor flow meters, and the second flow meter module 6 is equipped with 2 rotor flow meters. However, this is not a limitation. In other embodiments, the number of the first valve and the second valve can be set to other numbers according to the actual situation, and the number of rotor flow meters will be set accordingly.

[0022] See Figure 1The first flow meter module 5, the second flow meter module 6, and the monitoring module 7 are all located inside the housing 2.

[0023] See Figure 3 , Figure 3 The diagram illustrates the circuit connections of the monitoring module. Monitoring module 7 includes a data acquisition unit 71, a bus gateway 72, and a data transmission module 73.

[0024] The data acquisition unit 71 is connected to the rotor flowmeter 74 to acquire flow detection data. The data acquisition unit 71 is an industrial-grade 48-channel data acquisition unit, which has 48 data interfaces. In this embodiment, an industrial-grade 48-channel data acquisition unit with model number PN 84-8011-0390 is used. In this embodiment, the first flowmeter module 5 and the second flowmeter module 6 have a total of 16 rotor flowmeters. Figure 3 As shown, each rotor flowmeter 74 is connected to one interface of the data acquisition instrument 71, sharing a total of 16 interfaces. The connection status of these 16 interfaces is illustrated in the figure. The remaining interfaces are unused in this embodiment (not shown in the figure). However, this is not a limitation. In other embodiments, other numbers of rotor flowmeters can be set according to actual needs, but the total number of rotor flowmeters should be less than or equal to 48.

[0025] The data acquisition unit 71 is connected to the bus gateway 72 via a serial communication port. In this embodiment, the data acquisition unit 71 and the bus gateway 72 communicate using an RS485-1 interface and a data cable.

[0026] The data transmission module 73 is used to transmit data to the host computer. The data transmission module 73 can be either a wired data transmission module or a wireless data transmission module based on the actual situation.

[0027] See Figure 3 , Figure 3 The diagram also illustrates the neutral wire (N), live wire (L), and grounding protection wire (PE) in the monitoring module circuit.

[0028] The operation of the flow monitoring device for the lubrication system in this embodiment is as follows: After the lubrication system is running, the rotor flowmeters of the first flowmeter module 5 and the second flowmeter module 6 monitor the flow of the corresponding valves in real time. The electrical signals of each rotor flowmeter are input to the data acquisition instrument 71 of the monitoring module, and then transmitted to the host computer through the data transmission module 73. In this way, the staff at the host computer can obtain the flow of each lubrication point in real time, and thus make corresponding countermeasures to control the lubrication flow in a timely manner. The flow monitoring device for the lubrication system in this embodiment can significantly reduce the inspection work of the staff, and can provide timely feedback on the flow monitoring situation, improve the work efficiency of the staff, enhance the flow control effect, and achieve precise control of the lubrication flow while ensuring the lubrication effect of the bearings and gearboxes in the paper machine equipment, which is conducive to extending the service life of the equipment.

[0029] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
