Online Vibration Monitoring System (YVL Series)

The YVL series online vibration monitoring system is a continuous monitoring system for equipment. It can quickly and automatically collect data from remote, dangerous, or difficult locations. With this system, relevant vibration data of the equipment can be continuously collected, and the real-time status of the equipment can be grasped to timely detect possible faults. At the same time, the system can also integrate online oil monitoring data. By combining the vibration and oil data of the equipment, more accurate judgments can be made on the operating status and equipment faults of the equipment.

Vibration analysis is usually divided into two stages: trend monitoring and fault diagnosis. Trend monitoring refers to the regular measurement and trend tracking of vibration values, rotational speeds, etc. at a certain measuring point. When the trend state changes, it means that the machine state has changed (malfunction). The following figure shows the variation of vibration values at a certain measuring point over time. It can be seen that after running for a period of time, the vibration value gradually increases, and after maintenance (or replacement of parts), the vibration value significantly decreases again.

When the vibration value of a certain measuring point increases, it can be determined that the machine state has changed (malfunction), but the specific cause of the malfunction is still unknown, which leads to a lack of direction for the subsequent maintenance work. At this point, we need to enter the second level of vibration analysis: fault diagnosis. Fault diagnosis through vibration analysis refers to the use of advanced diagnostic methods equipped with vibration measuring instruments, such as vibration spectrum, envelope spectrum, time-domain waveform, etc., to determine the precise cause of the fault.

The YVL series vibration online monitoring system has the following characteristics:

Ø Economical solutions

A system can connect up to 120 vibration analysis signals, which can significantly reduce costs for individual machines. And adopting a wiring structure that combines buses and tap boxes greatly reduces the use of cables and lowers costs.

Ø Decentralization - Directly on-site

The system can be installed directly on the machine without the support of a PC and can be integrated into the company's data network.

Ø Quick installation

Short cables, sturdy installation techniques, and ready-made cables make the installation process of this system very fast.

Ø Supports signal acquisition from multiple devices

This system can connect vibration sensors, temperature, speed sensors, displacement sensors, oil quality sensors, etc., to monitor process parameters such as vibration, oil, temperature, etc.

Long distance transmission with minimal signal attenuation

The network transmission used by the system results in less signal attenuation during long-distance transmission, making it more suitable for long-distance transmission.

Flexible measurement tasks

Recording the passband values of a wide frequency band can provide information on the overall condition of the machine. On the other hand, monitoring specific fault frequency ranges provides reliable fault diagnosis. For variable speed machines, monitor and track their fault frequency bands. By selecting a specific frequency band, the influence of interference signals can be removed.

Ø Quick alarm

When the machine condition exceeds the limit value, the system can notify maintenance personnel through sound and light alarms or Ethernet, eMail, and other methods.

Ø User friendly interface

All characteristic values and instrument status information can be accessed and read through universal remote access, with a simple software operation interface and reasonable functional equipment.
