Poor perception of the quality of the installation of building mechanical and electrical equipment

Poor perception of the quality of the installation of building mechanical and electrical equipment
At present, there are more and more high-grade office buildings, luxury houses and star hotels in China's urban high-grade civil buildings, in these high-grade civil buildings, the requirements for decoration and installation of mechanical and electrical equipment will be higher and higher. However, we often find such phenomena in some high-grade buildings: floor corridor ceiling sprinkler heads, air outlets, lamps and lanterns are arranged crookedly not in a straight line: guest room bathroom sanitary ware, hardware fittings are not in the middle of the four corners of the decorative seams; ceiling leakage traces, bathroom carpet outside the water stains; the same type of switches on the inner wall, socket panel position is not the same height phenomenon, leaving a permanent, to the project The appearance is not beautiful regret. The author through their years of construction experience to analyze and summarize the construction of mechanical and electrical equipment installation quality perception of poor reasons are mainly the following: 1) mechanical and electrical engineering project department construction management is not in place. Engineering perception quality awareness is indifferent. 2) water, electricity, ventilation professional comprehensive layout between the deepening degree is not enough, resulting in some of the air outlet installation is not in place, the ceiling of some lamps and lanterns due to the installation height is not enough, can only be shifted to install. 3) The finished product protection measures are not in place, resulting in scratches, spots, cracks and other damaged phenomena on the surface of mechanical and electrical products.
Construction mechanical and electrical equipment noise and vibration is large
In recent years, China's requirements for environmental quality of construction projects are getting higher and higher, especially schools, hospitals, comprehensive office buildings, senior sprinklers and other buildings, the noise and vibration control requirements are very strict, and the root cause of noise and vibration is mainly equipment rooms. Because the equipment room are installed with refrigeration units, air conditioning circulating water pumps, air handling units, all kinds of fans, cooling towers, transformers, HVAC and water supply and drainage and other power mechanical and electrical equipment. These equipment operation due to the inertial force of rotation and eccentric imbalance generated by the disturbance force, will cause the equipment components to produce forced vibration, and through the equipment base, piping and the connection part of the building to produce vibration and noise. And in the form of solid and air sound waves to the surrounding space radiation noise for propagation. It brings impact to people's life, study and work. Therefore meeting people's requirements for environmental quality is an issue that should not be ignored in today's construction projects .
