Water ring vacuum pump (referred to as the water pump) is a rough vacuum pump, the English name of water ring vacuum pump. It is available to ultimate vacuum of 2000 ~ 4000Pa, atmospheric jet series of up to 270 ~ 670Pa. Water ring pumps can be used as medical gas compressor room, called water ring compressor is part of the low-pressure compressor professional medical gases, the pressure range of 1 ~ 2 × 105Pa gauge pressure. Overview water ring vacuum pump water pump initially used as a self-priming pump. By the impeller, pump, suction and exhaust tray, water pump water wall to form a ring, the intake port, exhaust port, auxiliary exhaust valves and other components. It is available to ultimate vacuum of 2000 ~ 4000Pa, atmospheric jet series of up to 270 ~ 670Pa. The water ring pump is also used as a compressor, a known water ring compressor, belongs to the low-pressure compressor, a pressure in the range of 1 ~ 2 × 105Pa gauge pressure. Lighting control box a normal use conditions, the ambient temperature is not higher than + 40 ℃, the average temperature in a 24 hour period of not more than + 35 ℃, the lower limit of the ambient air temperature is -5 ℃; control box 2, the air clean medical gas, the relative humidity at a temperature of + 40 ℃ when not more than 50%. At a lower temperature allows a higher relative humidity, for example: + 20 ℃ relative humidity of 90% for medical gas pipeline, should take into account changes in temperature may occasionally produce moderate condensation; 3, pollution degree 3 ; 4, the installation site altitude of not more than 2000 meters; 5, floor mounted vertically installed tilt shall not exceed 5 degrees; 6, no severe vibration and shock would not be sufficient corrosion of electrical switches and components place; 7, transport and storage temperature range between -25 ℃ ~ + 55 ℃, in a short time (less than 24h) up to + 70 ℃; professional medical gases _ Hebei Ericsson (certified) _ Medical Gas Lixin from Hebei Medical Engineering Co., Ltd. available.
