Description

technical field [0001] The invention relates to the technical field of degassing, in particular to a control system and a control method of an intelligent vacuum degasser. Background technique [0002] Vacuum degasser is an important equipment used in heating, heat exchange, refrigeration and other water circulation systems. Because there is a large amount of gas in the water circulation system, if it is not removed, the system is prone to air resistance, which will cause poor circulation and uneven heating and cooling of the local or entire system, and cause damage to the equipment and pipelines in the system. At the same time, due to the dissolved oxygen in the water, the terminal equipment such as heating (refrigeration) equipment, pipelines and steel radiators are corroded, perforated, and leaked, which directly affects the safety of the entire system. At the same time, the gas in the system will cause the cavitation of the water pump and the wear of the bearing and gen...

Problems solved by technology

Because there is a large amount of gas in the water circulation system, if it is not removed, the system is prone to air resistance, which will cause poor circulation and uneven heating and cooling of the local or entire system, and cause damage to the equipment and pipelines in the system

At the same time, due to the dissolved oxygen in the water, the terminal equipment such as heating (refrigeration) equipment, pipes and steel radiators are corroded, perforated, and leaked, which directly affects the safety of the entire system.

At the same time, the gas in the system will cause the cavitation of the water pump and the wear of the bearing and generate noise in the system pipe network

[0003] Existing vacuum degassers are generally controlled by time or liquid level, which have defects such as high energy consumption and inaccurate control
