7bar 185cfm Diesel Engine Powered Mobile Air Compressor Machine for Construction Work

Working principle of diesel air compressor 1. Inhalation process: The screw compressor has no intake and exhaust valve groups, and the intake is only regulated by the opening and closing of a regulating valve. When the tooth groove space of the main and auxiliary rotors is transferred to the opening of the air inlet end wall of the casing, the space is large. All are discharged, and when the exhaust is completed, the tooth gap is in a vacuum state.When it turns to the air inlet, the outside air is sucked in and flows axially into the tooth grooves of the main and auxiliary rotors. When the air fills the entire tooth groove, the end surface of the intake side of the rotor is turned away from the air inlet of the casing, and the air between the tooth grooves is sealed. The above is the “intake process”
2. Sealing and conveying process: When the suction is finished, the tooth peaks of the main and auxiliary rotors are sealed with the casing, and the air in the tooth grooves no longer flows out, which is the “closed process”. The two rotors continue to rotate, and the tooth peaks and tooth grooves match at the suction end, and the matching surface gradually moves to the exhaust end, which is the “transportation process”.3. Compression and fuel injection process: During the conveying process of the diesel air compressor, the meshing surface gradually moves toward the exhaust end, that is, the tooth groove space between the meshing surface and the exhaust port gradually decreases, and the air in the tooth groove is gradually compressed. The pressure is gradually increased, this is the “compression process”. While compressing, lubricating oil is also sprayed into the compression chamber to mix with air due to the pressure difference.
4. Exhaust process: Precautions for using diesel air compressors: The commissioning of new machines shall be carried out by designated or approved commissioning personnel. Pay attention to whether the direction of rotation of the motor is correct when starting the machine or changing the power cord to prevent the machine head from losing oil and burning. The diesel air compressor should be placed on a flat ground, and the ground should not be soft soil. When the main pipeline is piped, the pipeline has a downward slope of 1º~2º.
