I wanted to know what can be the maximum angle of tilt of plate of wobbling pump? Is there any critical value of this angle so that wobbling effect comes into play or what are the effects of increasing or decreasing angle?
"I wanted to know what can be the maximum angle of tilt of plate of wobbling pump?"
Increase it far as is physically possible and still work. As a practical matter 45 deg is pretty steep and the side thrust forces are equal to the axial. Wear increases and power consumption likewise. A variable wobbling plate angle can thus control pump output from zero to a maximum of what the pump is designed for.
Consult the catalog of a pump manufacturer for more detail information.
