GENERAL CRITICAL MACHINES:
VIBRATION PROTECTION AND CONDITION MONITORING SYSTEM:
Industrial Fans, FD Fan, ID Fan, PA Fan, Blower, HVAC Fan, Air Handler , Electric Motors, Steam Turbines, Expanders, Compressors, Pumps, Forced Draft Fans, Boiler Fans, Power Generation, Steam Power Plants, Compressors, Gears, Speed Changers, Journal Bearings, Ball bearing, Thrust Bearing
Machine drivers can be an electric motor, steam and gas turbine or an expander. Mostly, industrial turbines have journal bearings. Electric motors do not have thrust bearings and depend on a simple rider ring for shutdown.
Driven Equipment includes Blowers, Compressors, Fans and Pumps. Driven equipment are usually monitored and protected by 2 orthogonal transducers accelerometer for rolling element bearings and proximity probes for journal bearings
Many of the high pressure gas compressors or pumps in industry are of the reciprocating type. Two types of measurements are more common in these types of machines. First type is to measure the head cylinder overall vibrations by an accelerometer. The second type is to measure the rod drop of a piston rod to make sure that the piston rider bands are not worn out to dangerous levels which may lead to possible contact between the piston and internal cylinder walls. Rod drop is a long time trend from the mean distance between the proximity probe and the piston rod.
Recommended for walk around data collection routines, where the transducer is fixed and installed. Because changing the direction and point of measurement might affect measurement values, permanently mounted Accelerometers provide more reliable and repeatable readings and the local BNC Switch Box allows for faster, safer and more convenient data collection with portable data collectors or vibration analyzers. VIBSENS switch box works with all 3rd party data collectors and vibration analyzers.
This stand-alone analogue module which applies dynamic signal protection meets the requirements of API-670 and provides all the features of a standard vibration protection system able to excite relay output & transmit 4-20mA signal proportional to acceleration, velocity, or displacement to PLC/DCS or any standard 3rd party recorder. Moreover, BNC output for reading with portable data collectors, optional internal integrator, and transducer check display LED, current loop check, alarm relay outputs are all provided in just one module. Optional selection between delays in alarm, energized and non-energized relays are also embedded. Terminal for remote reset for alarm ignorance is also provided. It may be connected either to an ICP™ accelerometer or a proximity displacement probe, VC200A is a complete system which simply needs DC power supply and connected transducer with easy setup.
VC200T is a standalone analogue thrust position measurement & protection module which meets the requirements of API-670 for thrust (axial) position control and provides all the features of VC- 200A protection system with the addition of relay modules and 4-20mA output for PLC/DCS or other standard 4-20 mA recorders. Also BNC output for portable data recorders, current loop check and alarm relay is provided in the module. The ability to select alarm delay, energise and non-energised relay, terminal for remote reset is also provided. It operates with displacement proximity probes and measures and protects against DC part of the signal.
This module measures the piston rod drop for reciprocating machines and meets the requirements of API-670 providing all the features of VC210A with relay outputs as trip, and an on-board display to show the instantaneous value of rod drop values (either probe distance to rod or actual rider point). Besides that, VC200R has 4-20mA output signal which may be transmitted to PLC/DCS or any other standard recorder. Sensor error, Danger/ Alarm status , alarm delay, bypass, latching or non-latching relays, energise and non-energised relays are also provided. Three measurement modes which consist from reference point, average mode and maximum drop point of piston rod. Just like other transmitters terminal for remote reset / Modbus RTU (RS-485) protocol communication is supported.
V400 vibration measurement protection and condition monitoring system is a high performance fully programmable signal measurement system capable of measurement & monitoring 4 input channels of either types of absolute vibration (accelerometer / velocity transducer), relative shaft vibration (displacement proximity probes) or thrust (axial) position. In addition to this, first channel can be connected to a trigger signal (Keyphasor™) for measurement of rotational speed or vibration phase of other channels relative to a reference. This 9 cm *9 cm *18 cm panel mountable module is designed specifically for machine protection applications, offering a compact and cost effective solution for small and medium sized rotary machines. Terminal for remote reset / Modbus RTU (RS-485) protocol communication / embedded serial port for firmware update is embedded in each module. It can accept signal from all the standard API-670 compatible transducers and active / passive speed probes. All transducer signals are available via front BNC as buffered output for portable data collector connection. Two fully programmable output relays, 4-20 mA output for all input channels, white graphic LCD display, and four button keypad are all present to maximize onsite and local application.
