SSAN Digital Intelligent Automatic Series

                 


      Varieties for small parts, bulk large, to require a higher degree of automation users, Sigmar (Sigma) has developed a scientific automatic, super-programming as the main features of the scientific automatic VSR system.

    This series has SSAN100B, SSAN100-1B, SSAN80B, SSAN50B four specifications.

Parameters are as follows:
 



Functions as follows:

1, can be remotely operated 
2, Science Automatic
3, super-programming
4, single-function keys
5, large LED display
6, no slot permanent magnet motor
7, man-machine dialogue
8, overload, over-current, over-speed protection
9, the host, the electrical adopt a strong, weak isolation  

Integrated Features: Process more scientific.

Scope of application:
small breeds, large-volume workpiece.
 

     The following figure beam-shaped parts (a) scan was an curve in Figure (b), VSR based on scientific principles, to conduct modal analysis by the diagram (c) (d) is clearly visible: resonance frequency n1 could focus on the Elimination of A zone stress, n2 could focus on the Elimination of B, the stress. On the contrary, in view of the prior parameters are not familiar with the workpiece, if not analytical work, stress positions, does not analyze the peak and the vibration type and the corresponding region of the relationship between the workpiece on the principles according to pre-set limitations, we would often bring false prescription, leakage timeliness, arbitrary limitation.  Example: 
     Suppose the residual stress in the A zone, select the maximum amplitude while the frequency of n2 to the limitation has no effect on the A zone, that is incorrect prescription;
    Suppose the residual stress in the B area, select the frequency of the lowest frequency value n1 to aging, B, can not be achieved effect, that is false prescription;
    Suppose A, B District, have residual stress, if only select one of the peak (ie, a single peak) is always an area limitation has no effect, that is, leakage aging; because only the n1, n2 pairs of peak processing in order to make A, B District, are effective;
    Suppose A, B District, only one region of residual stress, both then in n2 with n1 piece will be brought to the limitation of time wasted, unnecessary motor wear and tear and noise, may also lead to weaknesses in the workpiece fatigue, that is arbitrary limitation . 
     In short, due to VSR control box (the host) can only identify an curve (b); while the vibration mode can only rely on the operator to the scene to personally identify, so the blind use of automatic equipment, aging methods will inevitably lead to wrong prescription, leakage timeliness, arbitrary limitation.  That is, only the operator of residual stress distribution according to the first turn, by identifying the vibration mode and then select a frequency effect was likely to be aging
 

Fault Self-Diagnosis
Sigmar VSR equipment in the digital panel designed a set of photo diode lights, which can be run according to the internal procedure of the host and the whole system operation, or light, or eliminate, thereby to indicate the different states, to the instructions input parameters or instructions or warnings in which the state of the machine operator, or the implementation of the Aging Process. 
   
Super Programming
1, in order to improve efficiency, reduce vibration, noise, motor wear and tear, increasing the scope of work or the scope of protection, the password can be programmed to configure your system to work a minimum speed value, the maximum rotational speed value and the overload current value. For the rated interval 1000-10000r/min equipment, such as: If a piece is known only in 3500r/mi Department has a natural frequency, you can configure your system the minimum value, maximum speed of 3000r/min and 4000r, respectively / min.  In this way, after booting the system automatically and quickly stabilized at 3000r/min,, and in the vicinity of 3500r/min limitation, followed by l speed to 4000r/min automatically shut down when. This eliminates the 1000-3000r/min and 4000-10000r/min two intervals meaningless vibration, noise, motor wear and tear. If the workpiece is known to be a limitation can be 10180r/min at the minimum, maximum speed were set to 9600r/min, 11000r/min (motor can be short more than 10% of rated speed), so that the system can only be in the speed of range of work. Another example of a workpiece is always a peak overload, it can temporarily overload current value transfer large (no more than 10% of rated current) to complete the peak of limitation. 
2, in order to facilitate large with large motor, small pieces with a small motor, a master password through the key input of the exciter can match the variety of specifications, which can avoid using an external switch may be others but mal-burning motor.
3, also designed the man-machine conversation function, programming can tell the current state of the host, suggesting that the next step, and misuse alarm.
4, edit, print work date, craft cards.
5、 may be prepared, curing will increase process, fixed speed technology, steady rate process, the dynamic aging process, large structure workpiece treatment process, multi-peak treatment process, complex treatment process components and other auto-process.

Science and Automatic 
     Automatic mode is the VSR input system in the pre-scan curve procedure automatically select parameters and decided to aging time, the limitation before the end of the operator can not interfere with the system, it can not adjust the parameters of a function. Most of them were obtained in the natural frequency scanning to find a natural frequency of the value of the lowest natural frequency of the limitation in its vicinity, or to find a peak of high natural frequency, timeliness in its vicinity, or the natural frequency of all the scans have limitations. This analytical work, the specific stress conditions are not fully automated approach might lead to leakage of timeliness, wrong prescription and arbitrary limitation. 
     For large quantities of a certain kind of artifact, in its optimum vibration worked out pre-conditions and a number of effective frequency, amplitude height, aging time, the effect evaluation method, scanning frequency parameters can be credited to the host and its parameters No, after the number of automatic processes can be automated under the conditions of the preparation to deal with the kinds of artifacts, this automatic process is scientific and practical.  Can store and perform the functions of this process is called science and automatic. It may not be the frequency limitation of the peak value of the lowest natural frequency, it may not correspond to the highest natural frequency of the peak acceleration. Been an effective treatment may be only one natural frequency, it could be two or more.  Scientific automatic also has the following functions:
A, working speed range can be predetermined;
B, automatic on-line printing of various stages of aging, on-line identify all the parameters,, Needless to stop and then output;
C, dynamic aging multiple peaks, automatic tracking natural frequency of change;
D, identify the working speed range of automatic monitoring of all the resonance peaks (harmonics can be said that the spectrum can be approximate), and then optimize the aging process;
E, S-line automatic processing of various materials within the workpiece; 
F, automatic monitoring and online printing aging results;
G, auto-complete dynamic limitation, steady rate, fixed rate, fixed speed and other technology; 
H, Sweep and aging can be automatically or cancel
