Waveguide inflator

Abstract

The invention discloses a waveguide inflator. The waveguide inflator comprises an air inlet valve, an air compressor and a fist drying cylinder; a first heater is arranged in the first drying cylinder, a first air inlet is formed in one end of the first drying cylinder, and a first air outlet is formed in the other end of the first drying cylinder; an air output of the air compressor is connected with a first air port P1 of a first directional valve through a first air conveying pipe, a second air port A1 of the first directional valve is connected with the first air inlet through a second air conveying pipe, the first air outlet is connected with a third air conveying pipe, the first air conveying pipe is connected with a fourth air conveying pipe which is connected with a first air port P2 of a second directional valve, a second air port A2 of the second directional valve is connected with the first air outlet through a fifth air conveying pipe, the first air inlet is connected with a second air port A3 of a third directional valve through a sixth air conveying pipe, and a third air port B3 of the third directional valve is communicated with outside atmosphere. Under the circumstance that drying cylinders do not need to be dismounted, the waveguide inflator achieves dehumidification of air drying agents.

Description

technical field [0001] The invention belongs to the technical field of air drying, and in particular relates to a waveguide inflator. Background technique [0002] The waveguide drying and pressurizing equipment is collectively called the waveguide inflator. Its main function is to inflate the antenna feeder system to maintain a certain pressure of dry air in the feeder system, to ensure that external moist air and moisture cannot enter, and to prevent excessive reflected power due to feeder rust. Large and other practical problems of electrical performance degradation or damage to the transmission feeder, to ensure the normal operation of the communication system, it is an important supporting equipment for the communication system. Waveguide inflators are widely used in radio and television, electric power, communications, oil fields, water conservancy, waterway transportation, meteorology, aviation, geology, military and other departments of microwave stations, radio and ...

AI Technical Summary

Problems solved by technology

[0003] Most of the current waveguide inflators need to replace the desiccant (canister). When the waveguide inflator works for a period of time, the desiccant changes color and loses its drying effect. It must be replaced regularly to ensure the drying effect of the waveguide inflator on the air. However, it is necessary to replace the drying cylinder It needs to be manually operated, and because the humidity of the air in different areas varies greatly, the replacement cycle is also different, which brings great inconvenience to the actual use of the waveguide inflator
