Gear pump in the use of coupling from the center of what to do

Gear pump coupling in use often off center, you need to constantly check the correction. When calibrating, pay attention to the following points: 1. Before the coupling is calibrated, if the coupling is uncoupled, check whether the rotation direction of the drive is consistent with the rotation direction of the pump. 2. Flexible coupling requires careful calibration of the center. Calibration can be done by placing shims under the motor. Corrective care, if careless, can result in damage to the coupling, the pump and the drive. 3. Under special circumstances, according to the requirements of the coupling manufacturer installation, calibration. For example: calibration, to ensure that the coupling between the provisions of the distance. Installation, please refer to the installation drawings and instructions coupling. Correction of a coupling without a middle section For a coupling without an intermediate section, a precision straightedge can be placed against the edge of the coupling and the parallelism between the straightedge and the axis can be observed at several points in the periphery or Check the distance between the couplings with a few plugs on the corresponding gauge. Correction with measuring instruments If more demanding corrections (operating speeds> 3600 rpm and couplings with intermediate section) are required, axial and radial measurements are to be made with a dial indicator and the maximum permissible diameter in the direction of the axis To the deviation and radial runout. Note: In the case of high working temperature (about 130 ℃), the coupling must be inspected under the actual working conditions. If the deviation out of range should be aware of, find out the reasons and discharge hidden dangers. In most cases, overshoot can be caused by excessive loads on adjacent lines.
