Note: The size and weight of the machine will be adjusted according to the specific working conditions, higher pressure or flow parameters are not listed
The discharge data is based on the standard 1 bar g/14.5 psig inlet pressure and 20℃(68°F)inlet temperature Please contact the technician of taike machinery company for the selection in high altitude area or high temperature operating environment.
Main drive system of W-type compressor
When designing the main drive system of W-type compressor, the selection of the included angle between the cylinders has a great impact on the dynamic performance of the compressor. It also mainly depends on the experience of engineers and lacks reliable theoretical analysis. Firstly, using ADAMS simulation software, the dynamics of the elastic crankshaft rolling bearing system of W-type compressor under rated working conditions is studied, and the central displacement response of the main journal and the bearing reaction force are obtained.
On this basis, the angle between the left, middle and right cylinders is taken as the design variable, and the weighted average of the radial displacement response amplitudes of the two main journals is taken as the objective function. The dynamic optimization is carried out in ADAMS, and the optimal angle value is solved.
