Industry Information

Electromechanical equipment plays an extremely important role in people's daily life development.Equipment installationIt directly affects the normal production, operation, and development of enterprises. Below, we will introduce in detail common issues related to equipment installation.

1) Not tight

During the installation and connection process, we must grasp the right degree of goodness. If the connection is too loose, equipment oscillation can easily occur during operation, and system resonance may even occur due to the same frequency. Mild cases can cause loud noise, even severe joint fractures, leading to accidents; Conversely, if the connection is too tight, it lacks the necessary buffer. Overnight, under prolonged mechanical and electromagnetic forces, the bolts simply show metal fatigue and loose joints, causing #naipan# between components to loosen and even lead to safety incidents.

If the compression is not tight, the contact resistance will increase, causing heat to generate and oxidize the contact surface when powered on, resulting in a vicious cycle of increased resistance. If severe overheating occurs, circuit breaks should be performed to create a grounding short circuit and disconnect incident.

2) Noise oscillation occurs

Electromechanical equipmentThe types are complex, mostly characterized by "movement," which means simple oscillations can cause noise pollution and potentially negatively affect normal hair growth days. These devices require a large amount of power to operate. Moreover, due to the inertial force of rotation and the disturbance force caused by the unbalanced pain of the equipment, equipment components undergo forced oscillations. As they pass through the base, wiring, pipelines, and other building junctions, vibrations and noise occur, radiating noise into the surrounding space in the form of solid sound and airborne sound waves, which then affects people's production and daily life. The primary reason for this issue is:

First, the pump rotor is unbalanced, the bearing clearance is large, the rotor and stator are rubbing, and the rotor and casing have poor coaxiality—all mechanical issues.

Second, the equipment installed the motor rotor is unbalanced, bearing clearance is large, and the air gap between the rotor and stator is uneven.

Third, during operation, the pump process parameters deviate too much from the rated parameters, leading to unstable pump operation.

3) Electrical equipment issues

First, when a barrier switch is installed, the touch pressure and movement of the contact area are insufficient, or improper operation can easily cause oxidation of the electric heating touch surface, which increases the touch resistance, then burns and erodes the contacts, leading to incidents.

Second, the finger and touch arc circuit breaker are incorrect #naipan# and touch pressure, causing the pulse to penetrate, synchronize and open and close at speeds that do not meet planning requirements, causing the contact temperature to overheat, extending the arc extinguishing time, leading to the decomposition of the insulating medium, sudden increase in pressure, and even causing the circuit breaker to burst.

Third, careless installation and protection of current transformers can cause primary winding openings, frequently causing high overvoltages and endangering equipment and personal safety.

Fourth, if the adjustment mechanism of the on-load pressure regulating equipment #naipan# is incorrect, it is possible that debris accidentally falls in during #naipan#, causing the mechanism to jam and cause varying degrees of trouble.

Fifth, the insulation of the equipment installed is damaged. When installing the main transformer to raise the iron core and high-pressure pipes, if debris accidentally falls, the main body and casing drainage is incomplete, sealing equipment is incorrectly installed or damaged during installation, etc. , the insulation strength of the main transformer will greatly decrease, causing partial insulation damage or breakdown, which can then lead to serious accidents.
