Control valve maintenance support system Azbil sales

PLUG-IN Valstaff is an on-line trend monitoring system for diagnostic parameters of intelligent valve positioner manufactured by Azibel Corporation during plant operation, early detection of bad condition of control valve and valve positioner, reduction of malfunction, visualization of decision to maintain control valve and improvement of maintenance business. Efficiency control valve maintenance support system.
PLUG-IN Valstaff communicates with the intelligent valve positioner corresponding to FOUNDATION fieldbus or HART communication, and monitors the valve diagnostic parameters 24 hours, 365 days. The diagnostic information can be used to detect the bad state of the regulating valve, supervise the disposal of the regulating valve before it breaks down, and contribute to the continuous and safe operation of the factory.
In addition, PLUG-IN Valstaff supports automatic adjustment of valve body and valve positioner settings, and automatic step response checking, which can be started quickly and correctly. According to the diagnostic data recorded in operation and the step response check after shutdown, the state of the control valve can be indexed, and the proper maintenance plan according to the aging process condition can be put forward, which contributes to the optimization of the open inspection.

PLUG-IN Valstaff can be run on the Equipment Management System "Innovative Field organizer" or the Integrated Machine Management Software Package PRM < (Plant Resource Manager) produced by Yokogawa Motor Corporation. Monitor the trend of a large number of control valves online.
The data of diagnostic parameters of intelligent valve positioner are collected during the operation of the factory. The aging process or abnormal occurrence of the control valve can be predicted by graphical display. The operation of the factory can be carried out online.
Step response check

It is the function of step response checking through PLUG-IN Valstaff when the factory stops. By comparing the results with those of the previous periodic maintenance, the aging or abnormal condition of the control valve can be found from the change of the response waveform. In addition, the quantitative dynamic characteristic data of time constant, delay time and setting time obtained from the inspection results are useful for the performance evaluation of the control valve. The inspection can be automatically carried out on a number of control valves, regular maintenance when a large number of inspection can be carried out at night. It can shorten the working hours.
Automatic setting

Automatic setting is the automatic adjustment function of locator from PLUG-IN Valstaff. The automatic setting can monitor the action of the regulating valve and adjust it while confirming the abnormality of the automatic adjusting process.
In addition, the travel time and backlash data detected in the automatic setting can be compared with the data in the past when the automatic setting is performed, and the aging or abnormality of the regulating valve can be simply inferred.

Monitoring the online trend of regulating valves
The following diagnostic graphs support collecting data on diagnostic parameters of valve positioners during factory operation, and speculating on the process or abnormality of valve ageing.
Motion distance accumulation
Calculate the action distance of the valve shaft.
As an indicator of the maintenance cycle of the seal parts, the operator seal and the guide parts.
Totally closed times accumulate
Count the full closed times and display the full closed times according to the time series.
As an indicator of the wear and plastic deformation of the valve seat.
Reversal times
The number of reversal actions of the control valve is counted and displayed in time sequence.
As a diagnostic index for mobile parts such as fillers.
Frequency distribution of opening degrees
In a certain opening area, the valve relative to the total number of occurrences according to what frequency operation ratio.
It is an indicator to confirm the valves size, to detect the blockage tendency in the valve or piping, and to predict the stem damage caused by low opening operation.
Maximum action speed
Inside the positioner, the operating speed of the opening direction and the closing direction of the regulating valve are detected at any time, the maximum speed of each day is calculated, and the maximum speed of each opening and closing direction is displayed in time series.
It is an index to detect the movement aging of the gland, the aging of the guide part and the leakage of the manipulator.
Crawling diagnosis
Determine the trend of crawling movements.
It is an index for detecting the ageing of the cap movement, the fixing tendency of the guide part and the bending of the valve stem.
Opening deviation
Collect the opening setting value and actual opening value of the regulating valve with graphic display.
It is the most basic index to judge the operation characteristics of regulating valve.
