We all know that the operation of the laser cutting machine is inseparable from the supporting air compressor. The laser cutting supporting air compressor ensures the normal use of the machine by continuously delivering fresh gas to the laser cutting machine. Below we will discuss the laser cutting supporting air compressor. The specific working principle, etc., will be introduced to you:
The working principle of laser cutting supporting air compressor:
The basic structure of the air compressor for laser cutting: In the compressor body, a pair of helical rotors meshing with each other are arranged in parallel. Usually, the rotor with convex teeth outside the pitch circle is called male rotor or male screw. The rotor with concave teeth in the pitch circle is called a female rotor or a female rotor. Generally, the male rotor is connected to the prime mover, and the male rotor drives the female rotor to rotate a pair of bearings on the rotor to achieve axial positioning and withstand the pressure in the compressor. axial force. Cylindrical roller bearings at both ends of the rotor enable radial positioning of the rotor and withstand radial forces in the compressor. At both ends of the compressor body, openings of a certain shape and size are respectively opened. One is for suction, called the intake port; the other is for exhaust, called the exhaust port.
Air compressor for laser cutting
Working principle of laser cutting supporting air compressor: The working cycle can be divided into three processes: intake, compression and exhaust. As the rotor rotates, each pair of intermeshing teeth sequentially completes the same work cycle.
1. Air intake process: When the rotor rotates, the space between the tooth grooves of the yin and yang rotors is large when they turn to the opening of the air inlet end wall. When the exhaust is completed, the tooth groove is in a vacuum state. When it is turned to the air inlet, the outside air is sucked in and enters the tooth groove of the yin and yang rotor along the axial direction. When the gas fills the entire tooth groove, the end face of the inlet side of the rotor turns away from the air inlet of the casing, and the gas in the tooth groove is closed.
