1. Central Air Conditioning System Central air conditioning includes air-conditioning refrigeration units, cooling towers, circulating water pumps, heat Pump units, and pipeline pumps.
2, power supply system Various transformers, transformer boxes are often placed in the basement or equipment layer, its low-frequency electromagnetic sound and vibration greater impact.
3, heating system Boiler house is generally placed in the basement or on the ground equipment layer, whether it is a gas boiler or an oil-fired boiler, burner noise and flue vibration, will have an impact on the inside.
4. The operating noise of the elevator and the vibration of the engine room are often neglected. It is very difficult to rectify the problem.
5. Water supply and drainage system The noise and vibration of the pump, such as the feed pump, the drainage pump, the pool hot and cold water pump, and the fire pump, as well as the sound transmission of the pipeline, are one of the key points of governance.
6, Ventilation system High-rise buildings are mostly closed structures, indoor ventilation is particularly important, various types of air-conditioning wind box, exhaust fan, new fan, exhaust fan and underground garage exhaust fan, etc., a large number of air volume, a wide range of impact.

Downhole tools for oil rigs include: stabilizers, scrapers, centralizers, etc.
The replaceable sleeve stabilizer are available with two-piece and three-piece construction. The three-piece construction stabilizer is made of a body and a centralizing body(refer to sleeve replaceable). The advantage is that the sleeve can be changed quickly and easily after sleeve hardfacing is worn-out. This kind of stabilizer is especially suitable for working in directional well .
