What are the applications of mining vibration sensors?


Mining vibration sensor is a major piece of equipment in modern industry, the rapid development of sensor technology and a wide range of mining vibration sensor application space, multi-functional, digital, intelligent both mining vibration sensor has been favored by the market, then, the following together to understand the application of mining vibration sensors have it!


What are the applications of mining vibration sensors?


The rotating parts of these mechanical devices each have a specific vibration frequency. The amplitude of their vibration is indicative of the working condition and quality of work of that machinery and equipment. An increase in amplitude can be a direct indication of failure of rotating components such as bearings, gears, etc. For rotating machinery, signals from vibration signals are mainly analyzed at this stage. For the pump, the main feature of the pump important failure is that the machine is accompanied by abnormal vibration and noise. Its vibration signal can reflect the fault information of the pump in real time, and the application of vibration sensors can monitor the operating status of the pump in real time, so as to detect the fault information in a short period of time, and remind the maintenance personnel to take measures to ensure that the pump works normally and improves work efficiency.


Mining vibration sensor is one of the key components in testing technology, its function is mainly to receive mechanical quantity and convert it into proportional electrical energy. This is because it is also an electromechanical transducer. Therefore, it is sometimes referred to as a transducer or pickup, etc. A vibration sensor is not capable of directly converting a mechanical quantity that is intended to be measured into an electric quantity, but rather, the mechanical quantity that is intended to be measured is used as an input quantity to the vibration sensor, which is received by the mechanical receiving section, and other mechanical quantities suitable for conversion are formed and converted into an electric quantity by the electromechanical conversion section. Therefore, the operating performance of a sensor is determined by the operating performance of the mechanical receiving section and the electromechanical conversion section.


Pump room or unit vibration, should be based on the specific circumstances, the use of vibration sensors for detection, one by one to analyze the cause of vibration, to find out the crux of the problem and then take appropriate technical measures to be removed. Industrial vibration analysis technology is a detection tool to confirm, predict, and prevent the failure of rotating machinery and equipment. The implementation of vibration analysis of machinery and equipment has the potential to improve the reliability and operational efficiency of machinery and equipment, reduce downtime and remove motor failure. Vibration analysis technology is a world-wide tool for identifying equipment and machine failures, setting up equipment maintenance schedules, and keeping equipment and machines working properly for as long as possible.


What is the classification of mining vibration sensors?


1、eddy current type

Eddy current sensor is the use of sensor end and the distance between the measured object changes to detect the object vibration displacement and amplitude of the relative non-contact sensor. Eddy current sensors have a wide frequency range, a wide linear operating range, high sensitivity, non-contact detection and other advantages, mainly used in static displacement detection, vibration displacement detection, rotating machinery rotor shaft vibration detection monitoring.


Electrodynamic sensors are based on the principle of electromagnetic induction. That is, when a moving conductor cuts a line of magnetic force in a fixed magnetic field, an electric potential is generated at both ends of the conductor. Sensors made using this principle are called electrodynamic sensors. The relativistic electrodynamic sensor is a displacement sensor in terms of the principle of mechanical reception, which applies the law of electromagnetic induction to the principle of electromechanical conversion, and generates an electromotive force that is proportional to the vibrational velocity being measured, which is actually a velocity sensor.


2、Electrostatic capacitance

There are usually two types of capacitive sensors. That is, variable gap type and variable common area type, variable gap formula can measure the displacement of linear vibration, variable area formula can measure the angular displacement of torsional vibration.


3、Guide type

According to the relativistic mechanical reception principle of the sensor, the inductive sensor can convert the change of the measured mechanical vibration parameters into the change of the electrical parameter signal, therefore, the inductive sensor has two forms of variable gap and variable permeability area.
