In the same compressor, each cylinder has a different compression ratio and a non-front-and-back-stage relationship.
In the same compressor, small and similar step-by-step compressors are used to form a front-and-back relationship to increase the pressure of the medium. The compressor is a reciprocating speed compressor with a moving mechanism. Compressors with less common motion mechanisms driven by gas engines are also called motorcycle positive compressors. The internal combustion power directly compresses the return stroke and synchronization of the positive compression piston without an output shaft through the opposing piston, and uses the air cushion effect and synchronous machine control to complete the magnetic field of the alternating magnetic field to connect the weak moving piston to the atmosphere for linear motion to complete the positive compression cycle.

Full standard suction position Full temperature of the gas
The suction temperature reduction of the first stage of the compressor is called reverse The gas temperature at the standard non-gas hood is the total temperature of the gas www.bzxz.net
. The controlled gas temperature of the compressor is called the gas delivery temperature. The gas compressed and discharged by a certain stage of the compressor, at the standard non-gas hood, is converted to the intake temperature, and the value of the reverse air pressure month and its correction value (read the plan)
The exhaust temperature of the compressor stage is the gas delivery
The value when the gas delivery volume is converted to the standard working condition (temperature Lika). The main defect of the compressor that moves the shaft in unit time is the limit position of the outer end or the inner end of the shaft. The distance from the outer stop point to the inner stop point when it is blocked at the stop point can accommodate the residual gas in the cylinder. Value method: the volume of air swept in one stroke; the ratio of the swept volume to the stroke volume

A dimensionless number that characterizes the difference between the actual gas state and the gas state. According to the distance between the adjacent cylinders
, that is, pressure as the level standard and stroke as the horizontal coordinate, there is also a table with the main angle as the horizontal coordinate, measured by an indicator to show the change of gas transfer within the working volume with stroke or rotation.
The force value after the ratio indicator diagram is converted into a rectangle of the same area. In each column of the compression machine, the direction of the piston axis is based on the algebraic sum of the gas force on the piston, the reciprocating inertia force and its friction force. The degree of rotation of the crankshaft is usually taken as the calculation origin when the cage is at the outer stop point.
The distribution between the two adjacent crank planes intersecting the axis of the shaft takes the piston force as the horizontal coordinate, the stroke as the horizontal coordinate, and the right main rotation angle as the horizontal coordinate. The graph showing the change of piston force with stroke is applied to the crank pin of each column of the compression machine, and the force
