Specification:

• The negative pressre of the medicl center suction system is not highter than 0.02MPa（150mmHg）and not lower than 0.07MPa (525mmHg) in the atmospheric environment, and can be ajusted abitrarily within this range

• When the negative pressure value is higher than 0.019MPa or lower than 0.073MPa (550mmHg), the sound and light alarm

• Ambient temperature range: +5℃~+40℃

• Working presure range 86Kpa～106Kpa

• Power supply votage: a.c. 380V3N~,50Hz

• lnput power: 5KVA

• The number of bateria per cubic meter of the air dischared from the exhaust port is ≤500

Structure characteristics:

The medical central suction system is composed of a central suction station, pipelines, and valves. The central suction station is composed of a vacuum pump unit, a vacuum continer, a pipeline, a valve, an electric control cabinet and a vacuum instrument.

Working principle:

The electric contol cabinet controls the start and stop of the vacuum pump. When the negative pressure in the vacuum tank reaches -500 mmHg, the vacuum pump automatically stops; when the negative pressure in the vacuum tank reaches -300 mmHg, the vacuum pump starts automatically. The upper and lower pressure limits of the automatic opening and closing of the control pump can be adjusted according to the requirements of the hospital. The vacuum pump can be started and closed automatically or manually.
