Double-air-source air path automatic switching pressurizer

Abstract

The invention relates to a double-air-source air path automatic switching pressurizer, which comprises a main air pump, an auxiliary air pump, a main electromagnetic valve, an auxiliary electromagnetic valve, a pressure gauge, an electric controller, a pressure compensation air bag, a non-return valve, a pneumatic valve, a main air duct, an auxiliary air duct and a pressure sensor, wherein the main air pump is communicated with the pneumatic valve through the main air duct and the main electromagnetic valve; the auxiliary air pump is communicated with the pneumatic valve through the auxiliary air duct and the auxiliary electromagnetic valve; both the main air pump and the auxiliary air pump are connected with the pressure compensation air bag through the non-return valve; the pressure gauge is installed on the main air duct; the main electromagnetic valve and the auxiliary electromagnetic valve are controlled by the electric controller; and the pressure gauge is connected with the electric controller through the pressure sensor. When the main air pump breaks down, the pressurizer can automatically switch into the auxiliary air pump to supply air, and can ensure air supply under stable pressure, thereby ensuring normal work of the pneumatic valve.

Description

Technical field: [0001] The invention relates to a gas path conversion device, in particular to a dual air source gas path automatic conversion pressure maintaining device. Background technique: [0002] Pneumatic valves are more and more used in various industrial equipment. The work of pneumatic valves is controlled by high-pressure air or high-pressure nitrogen. In order to reduce costs, manufacturers generally use high-pressure air to control pneumatic valves, and air compressors generate high-pressure air to supply equipment. Use, most manufacturers now use a single air supply, once the air compressor fails, the high-pressure air source will disappear, the pneumatic valve will not work properly, affecting the operation of the production equipment, for example, in the production process of solar cells , Many production equipment needs water, such as cleaning equipment and cooling equipment in the production process of solar cells, the control of water supply pipelines is...
