It is indicated that effect of variation of piston-to-cylindergap, oil temperature and pressure on simulation result is very small;
结果表明，柱塞—柱塞套间隙、机油温度和压力变化对模拟计算结果影响很小；
2
The machine is fixed by the motor and roll and roll to mobilize, the base, into the hopper of the clay through the cylindergap was crushed.
本机是由电动机及固定辊和可调动辊、底座、进料斗组成，粘土通过滚筒间隙而被粉碎。
3
Helical port also produces swirl by airflow interaction of valve gap and cylinder wall, so swirl number depends on helical line direction of relevant cylinder center.
