How to place the air compressor in the factory? The compressed air system is generally placed in the compressor room. Generally, there are two situations: one is to install in the same room with other equipment, or it can be a room specially designed for compressed air system. In both cases, the room needs to meet some requirements in order to facilitate the installation and work efficiency of the compressor.
01. Where should you install the compressor? The main rule of compressed air system installation is to arrange a separate compressor center area. Experience shows that no matter what industry, centralization is always better. Besides, it also provides better operation economy, better design of compressed air system, better service and user-friendliness, prevention of unauthorized access, proper noise control and simpler possibility of controlled ventilation. Secondly, separate areas in the factory for other purposes can also be used for compressor installation. Such installation should consider certain risks and inconveniences, such as interference caused by noise or ventilation requirements of compressors, physical risks and overheating risks, condensation and drainage, dangerous environment (such as dust or flammable substances), corrosive substances in the air, space requirements for future expansion and service accessibility. However, installation in workshop or warehouse can facilitate the installation of energy recovery. If there is no facility for installing the compressor indoors, it can also be installed under the roof outdoors. In this case, some problems must be considered: the freezing risk of condensed water, the rain and snow protection of air intake, air intake and ventilation, the required solid and flat foundation (asphalt, concrete slab or flat tile bed), the risk of dust, flammable or corrosive substances and the prevention of other foreign objects from entering. 02. Compressor placement and design Distribution system wiring should be carried out for the installation of compressed air equipment with long pipes. Compressed air equipment is installed near auxiliary equipment such as pumps and fans, which can be easily repaired and maintained; The location of the boiler room is also a good choice. The building should be equipped with lifting equipment, the size of which should be used to handle the heaviest components (usually motors) in compressor installation and forklift trucks can be used. It should also have enough floor space to install additional compressors for future expansion. In addition, the gap height must be enough to hang the motor or similar equipment when necessary. Compressed air equipment should have floor drain or other facilities to treat condensed water from compressor, aftercooler, gas storage tank, dryer, etc. The installation of floor drain must comply with municipal regulations. 03. Room infrastructure Generally, only a flat floor with enough load is needed to place compressor equipment. In most cases, the equipment is integrated with shockproof function. For the installation of new projects, each compressor unit usually uses a base to clean the floor. Large piston machines and centrifuges may require a concrete slab foundation, which is anchored on bedrock or solid soil foundation. For advanced and complete compressor equipment, the influence of external vibration has been minimized. In the system with centrifugal compressor, it may be necessary to suppress the vibration of the foundation of compressor room. 04. Air intake The air inlet of the compressor must be clean and free from solid and gas pollution. Dust particles and corrosive gases that cause wear are particularly destructive. The air inlet of the compressor is usually located at the opening of the noise reduction housing, but it can also be remotely placed in the place where the air is as clean as possible. If the gas polluted by automobile exhaust is mixed with the air to be inhaled, it may cause serious consequences. Pre-filter (cyclone separator, panel filter or rotary belt filter) is applied to devices with high dust concentration in the surrounding air. In this case, the pressure drop caused by the pre-filter must be considered in the design process. It is also beneficial to keep the intake air at a low temperature, and it is appropriate to transport this air from the outside of the building to the compressor through a separate pipeline. It is important to use corrosion-resistant pipes and mesh at the entrance. This design greatly reduces the risk of sucking snow or rain into the compressor. It is also important to use pipes with large enough diameter to obtain the lowest possible pressure drop. The design of intake pipe of piston compressor is particularly important. The pipeline resonance caused by the acoustic standing wave caused by the cyclic pulsating frequency of the compressor will damage the pipeline and the compressor, and affect the surrounding environment through irritating low-frequency noise. 05. room ventilation The heat in the compressor room is generated by the compressor and can be dissipated by ventilating the compressor room. The amount of ventilation air depends on the size of the compressor and the cooling method. The heat taken away by the ventilation air of the air-cooled compressor accounts for about 100% of the motor consumption. The energy taken away by the ventilation air of water-cooled compressor accounts for about 10% of the motor energy consumption. Keep good ventilation and keep the temperature of the compressor room in a suitable range. The compressor manufacturer shall provide detailed information about the required ventilation flow. There is also a better way to deal with the problem of heat accumulation, that is, to recover this part of heat energy and use it in buildings. Ventilation air should be inhaled from outside, and it is best not to use long pipes. In addition, the air inlet should be avoided as low as possible, but it is also necessary to avoid the risk of being covered by snow in winter. In addition, the risk that dust, explosive and corrosive substances may enter the compressor room must be considered. The ventilator/fan should be placed on the wall at one end of the compressor room, and the air inlet should be placed on the opposite wall. The air velocity at the vent should not exceed 4 m/s. In this case, the thermostat-controlled fan is the most suitable. These fans must be sized to handle the pressure drop caused by pipes, external shutters, etc. The amount of ventilation air must be sufficient to limit the temperature rise in the room to 7-10 C. If the ventilation and heat dissipation effect in the room is not good, water-cooled compressor should be considered.
