ExistInstallation of electromechanical equipmentIn the setup stage, equipment adjustment, testing, trial operation, and inspection are important steps in the project handling of electromechanical equipment installation and setup. However, some electromechanical equipment is small in size and difficult to install, and some have complex internal installation processes, requiring operators to be extra cautious. Are you familiar with the common technical challenges in electromechanical equipment installation? Below is a summary of the technical challenges that are easy to present in electromechanical equipment installation devices. Let's take a look and fully understand.
1) Bolt connection challenges.
The bolt connection isInstallation of electromechanical equipmentHowever, if the operation is improper or the connection is too tight, the long-term effects of electromagnetic and mechanical forces may cause metal fatigue in the bolts, leading to loosening of components such as shearing, thread slippage, and other components, which lays the groundwork for potential hazards. Especially in electrical engineering, when connecting bolts with conductive current, it is important to address the mechanical and electrothermal effects between bolts and nuts to ensure tightening and avoid adding touch resistance due to tightening, which could trigger a series of chain reactions, such as heating, contact surface oxidation, and resistance addition, which can lead to joint overheating, melting, grounding short circuits, and open circuits.
2) Oscillation Problem.
The causes of oscillation problems generally include three aspects:
(1) The pump is primarily affected by factors such as large bearing clearance, poor concentricity between rotor and housing, and excessive friction between rotor and stator.
(2) Motor causes include large bearing clearances, rotor imbalance, or uneven air clearance between stators.
(3) Device operation: If technical operating parameters deviate too much from the extra parameters, the pump's operational stability is easily unbalanced. The technical aspects of the oscillation device caused by unstable flow at the outlet valve must be as close to the extra parameters as possible.
3) Overcurrent problem.
In this case, there may be three possible reasons: pump bearing damage, foreign objects inside the equipment; Low motor overload current setting, high line resistance; The medium used in process operations has high density or viscosity, exceeding the pump's design capacity.
4) Electrical equipment challenges.
(1) Improper isolation switch devices, insufficient contact pressure and area at dynamic contacts, contact surface oxidation by electric heating, resistance addition, and contact ablation events.
(2) Circuit breaker arc contact refers to incorrect toucher installation, incorrect stab travel, touch pressure, synchronization, or connection speed not meeting requirements, toucher overheating, extended arc shutdown time, insulating medium differentiation, and sudden pressure increase, all of which lead to circuit breaker rupture.
(3) Installation errors of pressure conditioning equipment or debris falling into the tissue. If not handled promptly, it can lead to varying degrees of disputes.
(4) The main transformer insulation is damaged or broken down. If nuts or other debris fall into the main transformer's core and high-pressure pipe installation stages, errors in the sealing equipment installation can directly affect changes in the insulation strength of the main transformer, potentially causing partial insulation damage or damage, resulting in serious incidents.
(5) If the current transformer device is not properly protected, the open winding will generate high voltage, endangering people and equipment.
