MEDICAL AIR POWER PLANT TECHNICAL SPECIFICATIONS
The plant is equipped with the necessary equipment to deliver dry, clean and oil-free air to the hospital system. In case of failure of one of the central compressors, each of them shall be composed of at least two compressors, each of which shall meet the hospital needs. The connections between the Pipeline and the compressors must be made with flexible hose connections in order not to reflect the vibration in the compressor to the hospital line. The ends of the hose connections must be pressed and the connection elements at their ends must be prevented from coming out while under pressure. Compressed air plant
Compressed Air Compressors
Air Dryer (Chemical Type, Regeneration System, Heat-free)
Electrical Control Panel with Digital Display
4 -7 Atm regulation group
Compressed Air Tank should be an Air tank with a calculated capacity in accordance with the project values.
Definitions: Compressed Air Compressors must be oil spray air compressors. Compressors can be selected as Piston or Screw Type according to the capacity. The system should consist of at least 2 compressors, one of which is original and one of which is spare. Compressor working pressure max. There should be 10 bars. Operation The pressure range should be adjustable between 8 bar and 9.5 bar. The compressor must be directly coupled with an IP / 55 F class electric motor. Compressors are air cooled, Corrosion resistant stainless valve plates, Aluminum alloy cylinders and cylinder heads, Drain valves and check valves etc. should be equipped with. Compressors must have ISO 9001 and CE standard certificate. Compressed air dryers should be chemical type regeneration system air dryers with flow capacity at project values. The dryer must be composed of two groups and one of the chemical groups in the other group should be dried. During the operation of the drier, it should be possible to observe which group drier works with light indicators. There shall be devices on the dryer which will show the humidity and temperature of the outlet air of the two groups. Switches between groups on the dryer must be made manually or automatically. Thus, excessive wear of the chemical substance should be prevented. There should be filters and check valves on the dryer and back flow of gas from the hospital line to the plant should be prevented. There should be an audible and visual panel indicating the failure status of the pumps on the dryer panel and the pressure on the line. The Control Panel with Digital Display and the Dryer Panel should be on the same Control Unit. The air compressors can be controlled up to 4 compressors Sensor (Transducer) should be controlled by the instrument panel and the compressor operating and stop pressure values should be displayed digitally and these values should be programmed. These values should be set on the Compressor Screw Screw Compressor from the Control Panel. There should be a working program that enables the compressors to run in sequence and the first compressor changes every day, and this program should be capable of enabling the next compressor to be activated when the need increases.
The operation of the electrical control panel shall be capable of directing the following operation.
Electrical Control Panel should be digital display and transducer controlled. Compressor operating and cut-off pressures must be entered separately for each compressor on the front panel and must be able to control up to 4 compressors. In order to ensure that the compressors operate at equal hours, there must be an alternative operating system which selects which compressor starts first and whose replacement time can be set in days.
As the compressed air is used from the installation, the pressure sensor (transducer) should feel the pressure decrease, display digitally and the compressor selected at the set values should be activated automatically, provide the desired compressed air level and be automatically deactivated.
In case of overload or overload, if the reserve tank is empty and the air pressure is too low in the initial operating conditions, the main selector switch should take all the compressors into operation and ensure the required air pressure level quickly. compressors should be designed to operate one after another with short-term delays, and two or more compressors should not be activated at the same time, causing excessive current to be drawn from the system. As soon as the tank pressure level reaches a certain value, the selected actual compressor must remain active and the others automatically turn off. Thus, the last remaining compressor must be switched off after the maximum air pressure is required.
