The importance of compressed dry air for the communications industry

In the microwave communication system, the feeder line between the microwave transceiver and the antenna is tens of meters long. If the gas in the waveguide is wet, the water vapor will condense and corrode the inner wall of the waveguide, resulting in a decline in the quality of the microwave communication. The environment inside the waveguide is under a positive pressure, which is used to ensure that the waveguide leaks out, rather than other particles that are associated with preventing steam, dust, etc. from entering the waveguide. The particles in the waveguide cause reflections,Reflections can be measured as VSWR (Voltage Standing Wave Ratio) and result in signal loss or degradation. In most communication applications, the waveguide adsorption dryer will maintain a clean, dry, particle-freeEnvironment

The waveguide inflator can automatically fill a certain pressure of clean and dry gas into the waveguide according to the preset pressure value, so as to prevent the external humid air and moisture from entering, avoid the feeder from being affected with damp, and stabilize the transmission characteristics. In order to ensure the normal and reliable operation of the equipment and the stability of communication, regular inspection and maintenance must be carried out to keep the equipment clean, oil-free and dirt-free..

 

Waveguide inflator is an important auxiliary equipment in communication system engineering. It is mainly used for automatic inflation of waveguides of microwave stations, radar stations, satellite ground stations, radio and television transmitting stations or feeder systems composed of waveguide devices. The equipment can automatically maintain dry air with a certain pressure in these waveguides to ensure that external humid air and water cannot enter them and ensure the transmission quality of signals.

The waveguide inflator is composed of an air generation and processing unit, an electronic and electrical control unit and a flow meter unit. The air generation processing unit is composedCompressorRadiator,Gas-water separator and dryer, Gas storage tank, body, etc.; electronic and electrical control unit is composed of electronic module, electrical module, display, power switch, etc.; flowmeter unit is composed of flowmeter template and flowmeter module. The structure of the whole machine is reasonable and compact, and the installation, maintenance and expansion are convenient.
