Hydraulic injection molding machine atana back pressure control dan tur tarlan a ni. Hetiang method hian material dahkhawmna phase chhunga back pressure control chu injection cylinder leh oil tank inkarah first directional control valve, second directional control valve, pressure sensor, leh throttle valve dahin a ti thei a ni. Hydraulic injection molding machine chu material dahkhawmna phase-a a luh chuan.
Directional control valve hmasa ber A leh T port te chu hawn a ni a, oil return a intan ta a ni. Injection cylinder hnunglam atanga oil chu first directional control valve leh throttle valve hmangin oil tank ah a luang lut thin. Chutih rual chuan second directional control valve-a B leh P port te chu hawn a ni a, chu chuan oil tank atanga oil lo chhuak chu oil pump leh second directional control valve hmangin injection cylinder hnung lamah a luang lut thei a ni. Hetih lai hian PID controller chuan pressure sensor-in pressure value a hmuhchhuah chu a khawlkhawm chhunzawm zel a, pressure value a khawlkhawm atanga back pressure stability chu a ruat chhunzawm zel a ni. Back pressure a nghet loh chuan PID controller hian hydraulic injection molding machine oil pump output speed chu motor control-in back pressure a stabilize a, a control thin. A thatna chu control accuracy sang tak a ni a, hei hian high-precision back pressure control a siam thei a ni.
