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. /* January 22, 2024 19:08:37
