Mechanical equipment plays a very important role in the process of work and life. The quality of equipment installation directly affects the normal operation and development of enterprises. Therefore, equipment installation is a very important part of enterprise production. Therefore, in order to carry out the production smoothly, it is necessary to strengthen the installation technology of machinery and equipment, give full play to the efficiency, continuously improve the state of the equipment, prolong the service life, and bring the highest economic benefits to the enterprise. So, what are the common problems with the setup of the device? How to deal with it?

a) Assembly is not smooth

Generally speaking, one of the important tasks in the installation process of mechanical and electrical equipment is assembly, and the basic task of assembly is often accomplished through the connection of bolts and nuts. In this process, you must master the degree. If it is too loose, the frequency of the equipment is the same during operation, which may cause system resonance, make a lot of noise, interrupt the contact, and may cause a safety accident. On the contrary, if the joint is too tight, the necessary cushioning is lacking. Over time, the bolts are prone to metal fatigue under the long-term action of mechanical and electromagnetic forces. The joints such as shearing or screws sometimes become too loose, resulting in parts The assembly is loose, resulting in a safety accident.

When connecting bolts and nuts that conduct current in electrical engineering, full attention should be paid to the mechanical effect and electric heating effect. If the pressure is not tight, the contact resistance will increase, and it will be easy to heat up when energized, resulting in oxidation of the contact surface, resulting in a vicious circle of increased resistance. Burn the fused joint until it overheats, causing a short to ground and a separation accident.

b) generate noise and vibration

In recent years, people's environmental awareness has been continuously improved, the requirements for environmental protection are getting higher and higher, and the emphasis on noise is getting higher and higher. Electromechanical devices are diverse, the main feature being "mobile". It is easy to cause noise pollution, and in severe cases, it will adversely affect normal work and life. The equipment room is centrally equipped with power machinery and equipment such as refrigerators, air-conditioning circulating pumps, booster pumps, air handlers, cooling towers, various fans, transformers, heating, and drainage, which are the main sources of noise and vibration. These devices require a lot of power during operation, and the components of the device may have forced vibrations due to rotational inertial force and disturbance force caused by eccentric imbalance.

Noise is emitted through the parts of the equipment base, lines, pipes and other parts in contact with the building, and is transmitted to the surrounding air by solid sound and air sound waves, thereby affecting people's lives.
