Principle of air blowing optical cable
Air blowing optical cable is a safe and effective method for laying optical cables. During the cable laying process, the cable blowing machine simultaneously acts on the optical cable with the traction force of the tug, the blowing force of compressed air and the thrust of the conveyor belt. Therefore, an air compressor is needed to assist the cable blowing machine.
The air compressor generates compressed air, which is sent to the closed cavity of the cable blowing machine through the air hose. The lead-out end of the silicon core tube is connected to the closed space of the cable blowing machine. The tug used to pull the optical cable is placed in the tube together with the optical cable. The rubber around the tug is sealed with the inner wall of the tube, and the airtight container formed is connected to the closed cavity of the cable blowing machine. Therefore, the pressure generated by the compressed air pushes the tug to pull the optical cable forward in the tube. The air compressor continuously supplies air to ensure that the force applied to the tug is basically constant, thereby ensuring that the force applied to the optical cable is basically constant. At the same time, the compressed air flows forward, exerting force on the optical cable to push it forward, and on the other hand, it makes the optical cable suspended in the tube, reducing the friction between the optical cable and the inner wall of the sub-tube during laying, and protecting the optical cable to the maximum extent.
The high-pressure gas generated by the air compressor is quickly sent to the cable blowing machine through the connecting hose, driving the air pressure motor of the cable blowing machine, driving the upper and lower conveyor belts to rotate, and the optical cable is placed between the upper and lower conveyor belts, thereby pushing the optical cable forward.
