Learn about the rotational speed measurement range of the dynamic balance tester
First, the main function:
â— Versatility, can be used for tachometer, vibration measurement, vibration signal analysis, especially all functions with dynamic balance measurement. (immediate display of unbalanced vibration and phase)
â— Frequency analysis of machine vibration (maximum 1024 points for FFT)
â— Automatically use the test weight method to measure the influence coefficient and calculate the one-sided and two-sided permanent weights, or the known influence coefficient directly calculates the permanent weight according to the measured original vibration. You can calculate the edge and measure or calculate the capacity at one time. (Go try again or not try again)
â— It has the ability to calculate the calculated permanent weight to the left and right.
â— Has the frequency analysis ability to detect the same frequency, half frequency and frequency multiplication vibration component of the rotor.
â— Simple operation, the instrument automatically prompts, the general staff can use
Second, technical indicators:
1. Speed ​​measurement range: 400-30000 revolutions
2. Vibration measurement range: 0-3000 μm peak-to-peak
4. Remove unbalance rate >80% at one time
5. Phase tracking accuracy: less than ±1° within 0-360°
6. Display mode: Four lines of large character LCD display two measuring points at the same time
Third, the operation precautions:
The user does not press the "Reset" key during the continuous measurement process, otherwise all the data of the key will be lost. If you have an influence factor at hand, you can re-enter it.
Be sure to carefully do a good job of photoelectric sign to observe the accuracy of the machine speed. This is an important guarantee for the instrument to perform dynamic balance testing.
There are many reasons that cause the machine to vibrate. Only when the amplitude of the same frequency occupies a large component of the total amplitude, the dynamic balance method can reduce the vibration. On the contrary, the desired effect cannot be obtained.
In the dynamic balance test method, it is necessary to add the know test to the known position of the measured surface, and pay attention to the amplitude and phase of the vibration and the change of the original amplitude and phase of the vibration. If the data change is not obvious, the effect of vibration reduction after calculation is not obvious. If the amplitude change is not obvious, the weight of the test should be increased. If the phase change is not obvious, the position of the test weight should be moved again.
The sensor is equipped with a magnetic suction base that is very easy to grip. Please pay attention.
Balancing a rotor for the first time must be performed with a trial weight method. After the impact coefficient is obtained by the trial weight method, the same type of rotor can be balanced by the available influence coefficient method, and the operation is relatively simple.
The instrument can be powered by AC 220V, or it can be powered by an internal 12V battery. The general requirement is to use AC 220V to charge and 12V battery to supply power, so the internal noise is relatively small. Please note that when the battery voltage is lower than 10V, it is required to charge in time. Otherwise it will affect the battery life.
