精密注塑机的液压系统:
Hydraulic System of Precision Injection Molding Machine:
1) 油路系统需要采用比例压力阀、比例流量阀或伺服变量泵的比例系统。
1) Proportional pressure valves, proportional flow valves or servo variable displacement pumps are needed in oil system.
2) 在直压式合模机构中，把合模部分油路和注射部分油路分开。
2) In the direct pressure clamping mechanism, the oil pipeline of the clamping part and the injection part are separated.
3) 由于精密注塑机具有高速性

，为此必须强调液压系统的反应速度。
3) Because of the high speed of precision injection moulding machine, the reaction speed of hydraulic system must be emphasized.
4) 精密注塑机的液压系统，更要充分体现机电液仪一体化工程。
4) The hydraulic system of precision injection moulding machine should fully embody the integrated engineering of electromechanical and hydraulic instruments
