What is right?It means that two or more devices are arranged so that the rotation axis of the device after installation is connected by a coupling and the axis is on the same straight line in the running state.Good alignment means that the bearings, shafts and couplings are all in good stress conditions.
What will be the result of a bad heart?
1) The impact of poor alignment on the bearing overload and heat can cause damage to the bearing.
2) The impact of poor centering on the mechanical seal, damage to the sealing surface and seal leakage.
3) The impact of poor centering on the coupling, shortening the life of the coupling.
4) Vibration and noise of the equipment caused by bad heart.
5) Severe poor alignment will cause friction between moving and static parts, such as friction between wear rings, and between impeller and housing.
The rotation centers of the two shafts connected by the pump and the coupling should be strictly concentric, and the coupling must be accurately aligned and centered during installation, otherwise it will cause a lot of stress on the coupling and cause serious damage. Earthly affects the normal operation of shafts, bearings and other parts on the shaft, and even causes vibration or damage to the entire machine and foundation.Therefore, the search for pumps and couplings is one of the important work links in the installation and maintenance process.
