For order is possible effectively delivery of any quantity.
The monitoring system of the technical condition of rotating machinery CM-4 (CM4, CM 4)
 
A significant part of important equipment or power plants account for a large enterprise fans, exhaust fans, pumps and compressors for various applications. They have a large installed capacity and play an important role in the overall manufacturing process of the enterprise. For this reason, there is a need to equip these units with modern, efficient, relatively inexpensive system of stationary control of technical condition.
The monitoring system of the technical condition of rotating machinery CM-4 (Condition Monitoring - 4 Chanel) is designed for stationary monitoring and diagnostics of technical condition of large pumps, fans and smoke exhausts for different purposes.
The presence of built-in expert diagnostic systems greatly enhances the monitoring system.
The main difference of "CM-4" from standard systems vibration control is an integrated approach to assessing the technical condition of rotating machine.
In addition to measuring the vibration of bearings 4 of the unit, the monitoring system CM-4 technical condition of rotating equipment allows you to control the following parameters:
- Monitoring the temperature of 4 bearing assembly;
- Control the speed of the shaft assembly;
- Control and power supply current of one phase of the electric motor;
- Flow measurement and pump head.
With this amount of primary information can be more accurately value the technical state of the controlled unit. Possible to properly plan the amount and timing of repair and maintenance work. Monitoring of these important parameters of the equipment allows for the system security features and locks:
- Protection of equipment for the threshold values ​​of vibration, temperature;
- Motor overload protection;
- Taking into account the current developments of equipment.
With built-in device monitoring the technical condition of rotating machinery CM-4 Expert software diagnostic functions are implemented:
- Diagnosis of the presence of defects and assessment of technical state of the controlled equipment based on analysis of the spectra of vibration signals;
- Calculation of mass and angles set of balancing weights, if embedded expert system will be diagnosed with a defect such as "unbalanced rotor";
- Diagnosis of electromagnetic motor defects (eg, control of short-circuited rotor cage) on the basis of an analysis of the spectra of consumed electric currents and power.
Unique ability to instrument system for monitoring the technical condition of rotating machinery CM-4 is the ability to calculate the total efficiency of the pumping unit.This allows you to quickly assess the technical condition of the flowing part of the pump unit. Based on primary data obtained in the software are built hydraulic characteristics of the pump, which allows you to cook for the staff recommendations on the organization of the pump at peak efficiency.
If you have remote-controlled valve system, "SM-4" can itself provide a controlled pump unit work at peak efficiency.
The monitoring system of mark "CM-4" is mounted near the controlled unit.
Information on the status of the monitored equipment is transferred into the ACS for the RS-485.
