We design valves for highest efficiency, maximum service life and also for specific applications with the help of our high experienced specialists.
This allows to significantly decrease operating expenditures.
To design valves, we simulate their operation in compressor cylinders.
The mathematical model describes the dynamics of a system with a unit mass moving under the action of gas and elastic forces of springs elements, and is based on the equations of gas state, thermodynamics of variable masses, instant gas flow rates, gas dynamics and the dynamics of locking elements (valve plates).
to calculate optimal gas-dynamic characteristics depending on the shape of the flow part and the height of the valve plates;
to describe the dynamics of the movement of the locking elements, based on the actual stiffness of the springs, the mass of the moving elements and the frequency of rotation of the crankshaft;
to determine the loss of pressure and power, taking into account the type of compressible gas, the degree of pressure increase in the cylinders and the speed of movement of the piston.
The results of these calculations are displayed in tabular and graphical views, which clearly show the processes occurring in the valves during compressor operation.
The graphs show the relative values of the pressure drop and the height of the lifting plates, as well as the estimated speed of movement of the valve locking elements depending on the angle of rotation of the crankshaft.
