Hubei Yifan Construction Engineering Analysis What are the common problems in mechanical equipment installation?

Bolt connection is the basic assembly in electromechanical installation. However, if the connection is too tight due to improper operation, the bolt may be fatigued due to the long-term effect of electromagnetic force and mechanical force, which will lead to loose assembly of parts such as shearing and thread sliding, and bury hidden dangers. The causes of vibration problems usually include three aspects:

① The pump is mainly caused by factors such as large bearing clearance, poor concentricity between rotor and shell or excessive friction between rotor and stator.

② Motor, the reasons include large bearing clearance, unbalanced rotor or uneven air gap with stator.

③ Installation and operation, if the process operation parameters deviate too much from the rated parameters, it will easily lead to the imbalance of pump operation stability, such as the vibration caused by unstable flow control of outlet valve, which requires the equipment installation process to run as close as possible to the rated parameters.
