Abstract
The utility model discloses a vibration monitoring system of a fan. The vibration monitoring system comprises a magnetic sensing rotating speed sensor used for monitoring an amount of unbalance of the fan and a magnetoelectric velocity transducer, wherein the monitored signals are transmitted to a data collection analyzer by the magnetic sensing rotating speed sensor and the magnetoelectric velocity transducer, the key is that the system further comprises a PLC (Programmable Logic Controller) and a touch screen connected with the PLC controller, wherein the data collection analyzer is connected with the PLC controller through an RS485 bus. According to the utility model, measurement of a vibration amplitude, a vibration phase and a rotating speed of the fan can be monitored in a real-time manner, when the vibration of the fan exceeds standard, a user is timely prompted to carry out field dynamic balance of the fan, all data acquisitions, data analysis and computations and the like, all operations are achieved in a test analysis system, a data result is displayed on the touch screen directly so as to greatly facilitate a debugging process of workers and improve the efficiency.
Description
Technical field
The utility model relates to a kind of monitoring system.
Background technology
Usually blower fan need be debugged the vibration situation of blower fan in process of production, when large fan vibration values overgauge setting, must in time do transient equilibrium to rotor set, to prolong blower fan serviceable life.Fan vibration monitoring is at present mainly carried out field monitoring through the hand-held on-line detector and is realized, can not realize the real-time monitoring to fan vibration, has caused the prolongation of system debug time, has reduced production efficiency, has improved production cost.
The utility model content
The purpose of the utility model provides a kind of fan vibration monitoring system of real-time monitoring.
To achieve these goals; Adopt following technical scheme: a kind of fan vibration monitoring system; Comprise the magnetosensitive speed probe and the magnetoelectric velocity transducer that are used to monitor the blower fan amount of unbalance; Magnetosensitive speed probe and magnetoelectric velocity transducer are transferred to the data collection and analysis appearance with the signal that monitors, and it is characterized in that: said system also comprises PLC controller and the touch-screen that links to each other with the PLC controller, and wherein the data collection and analysis appearance links to each other through the RS485 bus with the PLC controller.
The utility model can be monitored fan vibration in real time, has accomplished the prevention ahead of time for vibration, and in time the dynamically balanced time of adjustment blower fan has been shortened in adjustment widely, has reduced the production cost.
Description of drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done and to be further described.
As shown in Figure 1; A kind of fan vibration monitoring system; Comprise the magnetosensitive speed probe and the magnetoelectric velocity transducer that are used to monitor the blower fan amount of unbalance; Magnetosensitive speed probe and magnetoelectric velocity transducer are transferred to the data collection and analysis appearance with the signal that monitors, and system also comprises PLC controller and the touch-screen that links to each other with the PLC controller, and wherein the data collection and analysis appearance links to each other through the RS485 bus with the PLC controller.
The utility model is the measurement of monitoring vibration amplitude, vibration phase and rotation speed of fan in real time;, in time remind fan vibration the user to carry out the blower fan spot dynamic balance when exceeding standard; All data acquisitions and data analysis calculating etc. are all accomplished in detecting and analysing system, and data result shows on touch-screen intuitively; Greatly make things convenient for staff's debug process, improved efficient.
