I. Overview
The SDM-811 single- and double-sided on-site dynamic balancer carefully developed and produced by the company provides you with a solution that cannot be solved by ordinary balancing machines--the assembly dynamic balance.
 
After the product is assembled, the rotating body will produce a phenomenon that does not meet the designer's desired effect due to process or other reasons. This is the vibration phenomenon caused by the workmanship, the deformation of the assembly, and the like. The vibration and displacement caused by the imbalance of the rotating body during operation can be greatly destructive. Greatly reduce the safety and longevity of equipment operation. For example, the impeller of the fan industry, the huge centrifugal force and mechanical vibration caused by the imbalance will cause the installation screws to break, the bearing wear and fatigue fission. Eventually it causes cracking or deformation of the rotation. These will shorten the life of the fan and pose a danger to the operator. With the on-site balancer, you can measure and correct the impeller without removing the fan impeller until the vibration is removed and the standard is reached.
 
 Dynamic balancer
Modern life has brought us a lot of new products from abroad. When we develop such products, we will bring a lot of new ideas in the processing industry. Such as: copy machine tools, CNC machine tools, etc. Its emergence has brought a new leap in the industry. However, when using such a machine tool to process some special workpieces, the machining position is not at the center of the fixture due to the special shape, and the workpiece is in an eccentric position. At this time, a certain weight should be attached to the eccentric clamp to minimize the vibration caused by the deviation of the rotation center. The machining speed of the workpiece is greatly improved, and the tolerance caused by the vibration is reduced, that is, the efficiency and the yield of the workpiece are improved.
 
SDM-811 single and double-sided field balancer is your best assistant. Its compact size and light weight make it easy to carry. Its new test concept and powerful software features, friendly display interface and menu-based operation make it easy for even inexperienced operators to quickly measure and eliminate rotor imbalances in minutes.

The SDM-811 single and double-sided field balancer uses the influence coefficient method to measure the balance meter. Its measured value accuracy is the working speed when it is measured, the scaled value, and the position of the sensor. There is an important relationship. When the measured speed range is low, the weight of the calibration should be larger due to the lower line speed; on the contrary, the weight of the workpiece measured at the high speed can be smaller, and the calibration value is not easy to fly out during the measurement. should.

Second, the computer briefly works
Working principle
   When the rotor rotates, the signals generated by the sensors mounted on the two test faces are applied to two identical input switch circuits. The component values ​​of the switching circuit are different on different balancing machines.
   The signal is integrated to eliminate the influence of the rotational speed, and then filtered to filter out the clutter signal, which is added to the automatic program-controlled amplifier circuit. After amplification, it is converted into a digital signal by AD conversion, and the digital signal is processed by the computer, and finally It is displayed on the screen.
 
Third, the balance meter installation and connection
installation method
   1) Hold one or two sensors with a magnetic seat on the bearing housing in the radial direction. Connect the sensor to the host computer with a cable.
   2) Connect the photo sensor line to the socket on the main unit
   3) The power supply of the unit uses 220v AC voltage and plugs the power cord into the socket.

Seven. System calibration:
     The support mode is set to 8 or 9 (8 is double-sided 9 for single-sided). Different machine measurements must be recalibrated due to changes in the mounting position of the sensor and the photocell. The same machine can be measured with the original calibration data if the sensor and photocell have not moved. The calibration process is as follows:
   Select “Operation” “Scale” in the menu and then press the prompt to start the calibration operation.
 1. When the support mode is “8”, it is measured on both sides. (You can press the Keyboard menu to bring up the on-screen keyboard to change the support mode. You can use the on-screen keyboard for all keyboard input later.)
    The first step (1) adds a known test weight to an angle to the left of the workpiece (generally added to zero). Figure:
      (2) Enter the magnitude and angle of the test weight.
     For example: Left test weight (g) Left angle (°)1.1 0
 
(3) Start-up measurement (Note: If the machine is slowing down and slowing down each time, you need to unplug the photoelectric head plug for each speed of the lift, and then connect it after the speed is stable. Otherwise it will affect the calibration result)
(4) Shut down when the red “ok” appears, and the left calibration ends.
The second step (1) moves the left test weight to an angle to the right of the workpiece (generally added to zero).
For example: Right test weight (g) Right test weight (g)11 0
(2) Enter the magnitude and angle of the test weight.
(3) Start measurement.
(4) Shut down when the red "ok" appears, and the calibration on the right ends.
 
The third step. Take the test weight off and start the measurement. A red "end" calibration is completed and the input save file is promoted.
 
After saving, the measurement is entered.
2. When the support mode is "9", it is single-sided. At this time, attention should be paid to the calibration. When the test weight is added to 0 degree, the input angle should be 0 degree. The operation is as follows:
The first step
(1) adds a known test weight to an angle to the left of the workpiece (generally added to zero).
(2) Enter the magnitude and angle of the test weight. Figure:For example: Left test weight (g) Left angle (°)1.1 0
(3) Start measurement
(4) Shut down when the red “ok” appears, and the left calibration ends.
 
The third step. Take the test weight off and start the measurement. Red "end" calibration is completed and the input save is saved
After saving, the measurement is entered.
 
Eight. Precautions:
1. The setting of the sensor should be placed in the radial position, generally set on the side of the bearing seat, the guide rail of the machine tool, and the bearing seat of the front box. It should not be set at the top, and it should be placed in a place where the sensor magnet can be stably and firmly absorbed.
 2, the photoelectric head is based on reflective paper reflection as a reference, should not be against the background of bright light. Place it in places such as the sky and lathe lights where there is a light source. The angle at which the reflective paper is adhered is generally set to 0 degrees, and the angle is calculated by calculating the angle in the reverse direction of the rotation direction. Figure:
