Description

Technical Field

[0001] This utility model relates to the field of air compressor monitoring technology, and in particular to an air compressor vibration monitoring device and system. Background Technology

[0002] While current mainstream online monitoring systems for air compressors can achieve real-time monitoring of core parameters such as voltage, current, power, key temperatures (exhaust temperature, main unit temperature, oil temperature), pressure, running time, and loading time, they have a significant shortcoming in the crucial area of ​​mechanical condition early warning—they have not yet integrated online vibration monitoring devices. Currently, equipment vibration detection still relies on maintenance personnel to conduct regular inspections using manual vibration meters. This method has significant limitations: firstly, it is greatly affected by human factors (such as measurement point deviation, differences in operating techniques, and data recording errors), making it difficult to guarantee the accuracy and consistency of vibration data; secondly, inspections are conducted at time intervals (such as once a day or once a week), making it impossible to achieve 24-hour continuous monitoring. This makes it difficult to capture sudden and intermittent vibration anomalies during equipment operation, often only discovering problems when the fault becomes apparent (such as abnormal noise or shutdown). This can easily lead to sudden equipment failures. Such failures not only cause air compressor shutdowns for repair but may also affect the normal operation of upstream and downstream equipment throughout the plant due to the interruption of compressed air supply. At the same time, the repair of sudden failures is more difficult, significantly increasing equipment maintenance costs and downtime losses. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the tendency for measurement point deviations caused by human factors when using a handheld vibration meter to monitor the vibration of an air compressor, and the inability to conduct continuous monitoring 24 hours a day, which makes it difficult to detect abnormal vibrations and cause subsequent equipment failures. This invention provides an air compressor vibration monitoring device and system.

The monitoring device also includes a power supply, which is electrically connected to the control terminal and the sensor assembly respectively. The sensor assembly is used to collect vibration signals from the air compressor; The transmitter is used to convert vibration signals; The control terminal is used to display the converted vibration signal.

[0005] This invention provides a vibration monitoring device for an air compressor. By setting up a sensor assembly and equipping one end of the sensor assembly with a magnetic connector, the entire sensor assembly can be connected to the air compressor via the magnetic connector. This eliminates the need for manual handling of the sensor assembly, ensuring a more stable connection between the sensor assembly and the air compressor. A transmitter is also located at the end of the sensor assembly furthest from the magnetic connector, and the transmitter is connected to a control terminal. After the sensor assembly collects vibration signals from a designated location on the air compressor, the transmitter processes (amplifies and filters) the vibration signal. The control terminal then receives and displays the processed vibration signal, allowing on-site personnel to directly observe changes in the air compressor's vibration. This enables personnel to detect changes in the air compressor's vibration in advance, identify potential risks, and initiate repairs, reducing the probability of air compressor damage.

[0006] Preferably, the sensor assembly includes a sensor body, one end of which is connected to the transmitter and the other end of which is provided with a monitoring surface, which is connected to the magnetic connector.

[0011] By setting up a signal receiving module, a signal processing module, and a display module in the control terminal, the automatic reception, analysis, and visualization of air compressor vibration signals can be achieved.

[0012] The signal receiving module ensures the integrity and real-time performance of vibration signal transmission; the signal processing module performs filtering, amplification, and feature extraction on the raw signal, improving the accuracy and stability of the data; the display module presents the processed vibration data in an intuitive digital or graphical format, allowing operators to promptly grasp the equipment's operating status and enabling real-time monitoring and fault warning of the air compressor's vibration condition. This design makes the monitoring process highly automated, data reading intuitive, and maintenance and analysis more convenient.

[0013] Preferably, the display module is a liquid crystal display screen.

[0014] In a second aspect, a monitoring system includes the aforementioned air compressor vibration monitoring device, the monitoring system comprising a plurality of the aforementioned sensor components.

[0015] This invention provides a monitoring system that, by setting up several sensor components, enables operators to monitor the vibration of various parts of an air compressor through these sensor components.

The control terminal centrally receives and processes the signals from multiple measuring points and displays the vibration data of each part in real time through a display module, making it convenient for operators to monitor the vibration of various parts of the air compressor.

[0026] Example 1 like Figure 1 and Figure 2 The air compressor vibration monitoring device shown includes a sensor assembly 1 connected to an air compressor. The side of the sensor assembly 1 facing the air compressor is provided with a magnetic connector 11, which enables a stable connection between the sensor assembly 1 and the air compressor. The end of the sensor assembly 1 away from the magnetic connector 11 is also connected to a transmitter 2, and a control terminal 3 is also connected to the transmitter 2. The monitoring device also includes a power supply 4, which is electrically connected to both the sensor assembly 1 and the control terminal 3. The monitoring device uses a magnetic connector 11 to stably connect the sensor assembly 1 to the air compressor, enabling the sensor assembly 1 to collect the vibration signal of the air compressor in real time. The vibration signal is then transmitted to the control terminal 3 via the transmitter 2. When the vibration signal passes through the transmitter 2, the transmitter 2 processes the vibration signal (amplification, filtering, and linearization), converting the vibration signal collected by the sensor assembly 1 into an industrial standard signal. This signal is then transmitted to the control terminal 3, where it is displayed. This allows operators to visually observe the vibration changes of the air compressor and take appropriate action when the vibration exceeds a certain threshold, preventing damage to the air compressor caused by excessive vibration changes going undetected. Furthermore, the control terminal 3 includes a signal receiving module, a signal processing module, and a display module; The signal receiving module is used to receive the converted vibration signal; The signal processing module is used to process the converted vibration signal; The display module is used to display the processed vibration signal; The entire conversion process is as follows: The sensor assembly collects the vibration signal (the physical quantities of vibration: displacement, velocity, acceleration) and converts it through transmitter 2 to obtain the converted vibration signal (which is the corresponding electrical physical quantity (current)); the converted vibration signal is amplified, filtered, and linearized in transmitter 2, and then converted into a digital electrical signal (discrete binary code) by an analog-to-digital converter; the control terminal receives the converted vibration signal and converts the converted vibration signal (discrete binary code) into a readable vibration signal (physical quantity data, such as vibration acceleration) through the signal processing module.

[0027] This application discloses a vibration monitoring device for an air compressor, comprising a sensor assembly 1, a transmitter 2, and a control terminal 3. One end of the sensor assembly 1 is equipped with a magnetic connector 11, allowing the sensor assembly 1 to be fixedly connected to the air compressor via the magnetic connector 11, eliminating the need for manual handling, thus improving installation convenience and ensuring the connection stability between the sensor assembly 1 and the air compressor. The transmitter 2 is connected to the end of the sensor assembly 1 furthest from the magnetic connector 11. The transmitter 2 processes the vibration signal of the air compressor collected by the sensor, including amplification and filtering. The processed vibration signal is transmitted to the control terminal 3 via the transmitter 2. The control terminal 3 receives and displays the signal, allowing on-site personnel to visually observe the vibration status of the air compressor. Through this device, personnel can promptly monitor the vibration changes of various parts of the air compressor and take timely maintenance or repair measures when abnormal vibration occurs or exceeds a preset threshold, thereby reducing the risk of damage to the air compressor caused by abnormal vibration and improving the safety and reliability of equipment operation.

[0028] Example 2 A monitoring system includes an air compressor vibration monitoring device according to Embodiment 1. The monitoring system includes a plurality of sensor components 1. By setting a plurality of sensor components 1, the operator can monitor the vibration of various parts of the air compressor through the plurality of sensor components 1. The vibration signals collected by each sensor component 1 are converted by a transmitter 2 and transmitted to a control terminal 3. The control terminal 3 centrally receives and processes the signals from multiple measuring points and displays the vibration data of each part in real time through a display module, so as to facilitate the operator to monitor the vibration of various parts of the air compressor.

[0029] In this application, the sensor assembly 1 can be installed in parts that need to monitor vibration, such as the air compressor head, motor, primary and secondary rotors, bearings, and gears.

[0030] Specifically, sensor assembly 1 is installed on parts of the air compressor that require vibration monitoring, such as the compressor head, motor, primary and secondary rotors, bearings, and gears. The monitored vibration signal is converted into an electrical signal and transmitted to the control terminal 3 via transmitter 2 and wiring. The control terminal 3 converts the received electrical signal into a readable value, allowing inspection and maintenance personnel to intuitively record the vibration value of the air compressor. By comparing the read value with the standard value, the operating status of the equipment can be judged, abnormalities can be detected in time, and preventive measures can be taken to prevent the fault from escalating and causing a sudden shutdown.

[0031] For example, the standard vibration value is 2-7 mm / s. If the reading exceeds this value, it is judged that the internal bearings or rotor may be faulty, and it is necessary to disassemble the machine for inspection and treatment in advance to avoid the damage of the faulty machine from escalating.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
