Balancing Module - Balance
Balancing module and machines balance
The balancing module of the MX 300 DSP Logger incorporates more accurate calculations for balancing machines, due to its powerful digital processing technology.
By a very simple procedure, which requires only the placement of an optical sensor to calculate phase and two readings of vibration for both planes, you get fast and accurate balancing.
The use of balancing program is easy to learn and operate, it can solve the problems of imbalances in minutes.
PROCESS:
The balancing process for 1 or 2 planes is almost the same.Two planes requires two sensors simultaneously, and two measurements.
First step is to rotate the piece to balance making the first measurement, then add a known weight to the piece and a second measurement is performed, once made these two measurements the system automatically will display the mass and position of the weight necessary to correct the imbalance.
The system lets you enter the weight in grams, test and make the correction in grams, or can enter the number of pallets if a fan is balanced and automatically calculates the weight distribution in each of them.
This balancing system allows you to change, during the process already initiated, the position and value of the testing weight input at the beginning of the calculations.
Balancing module can also make corrections in a row and at the end of the process, provide a total correction with a single weight and a single angle indicated.
This outcome or total correction is very useful when rotors weight have been distributed in different balances in different angles.
USEFULNESS OF REPORTS
The balancing module of the MX 300 DSP Logger has a very handy tool to record pre and post condition of the rolling process or balance.
Once set the parameters for the rolling operative, the system automatically measures and stores in memory a spectrum for each balance plane. Same does at the end of the process, giving an initial and final balancing spectral report.
Reports generated in a rolling process, contain the following informatión:
- RPM
- Values of initial and final vibration
- Added weight for correction
Besides these data, it also contains the spectra measured before and after rolling.
ISO 1940 QUALITY OF BALANCING
A new utility allows you to load data required by ISO 1940 to assure the quality of the balance.
indicating the result as per standard.
Balancing REPORT PARTIAL:
In the field of balancing, sometimes situations occur which may temporarily stop a rolling process, either by a machine out of service or a long time startup or shutdown turbine.For these cases the balancing module can restart the balance process.
picking up from memory a report already begun. This allows the operator not to lose the work done previously..
REPORTING SOFTWARE FOR WINDOWS:
The software allows you to connect your computer DSP Logger MX 300 with a PC and download the reports, print and store. It is free in any version.
