Analysis of the causes of the vibration of the gear reducer:
[The base vibration is large]
In some cases, the vibration of the reducer base is too large and has an influence. The vibration frequency of the base can be said to be the speed of the gear reducer, which may cause problems in the design of the base, resulting in an unstable state during operation.
[Rotor parts loose]
Some parts of the rotor of the motor: commutator, magnetic pole, pulley, etc., these loosening conditions will occur when the reducer is used for a long time. Generally, the rotor will have noise.
[Transmission machine imbalance]
When the calibration line of the motor and the driver in the gear reducer is not good, it is easy to generate vibration. To adjust the calibration line, reconnect the connection between the driver and the motor, which can stabilize the rotation of the motor bearing.
[Rotor mechanical imbalance]
The imbalance mentioned here is unbalanced in the case of unbalance and rotation of the rotor at rest, and the rotor is off-axis, and the deflection is generated by centrifugal force to generate abnormal vibration.
[Bearing wear is too large]
When the bearing works for a long time, the gap of the bearing is too large or unbalanced, resulting in frictional friction of the bearing. The most feared friction between the rotor and the stator will directly damage the bearing.
IECEx Approved Coriolis Mass Flow Meter
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Transmitter, Coriolis Mass Flow Transmitter, Coriolis Mass Flow Sensor, Mass Flow Sensor & Mass Flow Sensor Coriolis, ATEX, IECEx & CE approved.
The meter can be connected with computer as follows. Connect the meter and computer with a USB-to-RS485 converter( converter A+ end to transmitter A+ end, B- to B-, and GND to GDN); turn to device manager of the computer to check COM port connected with meter. Start the software, select the right COM port and click Connect; do not change any other parameters (if you do not know the right one, click Automatic options on the left, click Connect, plug & unplug the transmitter, and then check if it is connected). You can click Connect on the tool bar to disconnect or connect again. It will shown Connected/Not Connected at the bottom of this interface.
The flow direction is settable. There are 4 options, forward(default), reverse, absolute value & bi-direction. There is a direction mark on the sensor. Forward means the same direction with the mark on sensor, the meter will only count the flow in this direction; reverse means the opposite direction of the mark, the meter will only count the reverse direction; bidirectional means that the meter will measure both directions, it increases when it is forward and decreases when reverse; absolute means it increases no matter it is forward or reverse.
