Die casting machine hman kawngah chuan chutiang hlawhchhamna chu a tawk ngei ang. leh no total pressure chu cold chamber die casting machine . tan chuan fault pakhat a ni.
J118a 80ton cold chamber aluminum die casting machine a ni a, a man pawh a tlawm hle.
Total pressure a awm loh chuan a hnuaia check te hi zawm tur a ni:
Check and Analysis :Oil pump a start hnuah pressure button chu hmet la, pressure leh flow indication-te chuan proportional pressure valve solenoid-in current a neih leh neih loh hriat theihna tur indication a awm leh awm loh, electrical chu a fail leh failed emaw a nih leh nih loh emaw hriat theihna tur a awm leh awm loh hriat theihna tur indication a awm leh awm loh enfiah hmasa rawh.
Current output a awm chuan,i check tur a ni :
1) Oil pump chu a inher (mihring chuan oil pump shaft lam a hmachhawn em tih ,Clockwise rotation chu forward rotation a ni) a ni.
2) Relief valve chu a thawk tha lo em tih leh a tlakbuak em tih enfiah rawh .
3) Shutoff valve a khar em tih enfiah rawh .
4) Proportional relief valve a throttle valve chu a lo chhuak emaw, a lo awm loh emaw a ni em tih .
2. Current output a awm loh chuan,i check tur a ni :
1) Rectifier plate chu a pangngai em tih te, leh pressure proportional amplification board chu a dik lo taka siamrem emaw, a chhiat em tih te .
2) Computer-in hna a thawh dan tur dik leh dik loh enfiah tur, computer-a point inmil chuan input a neih leh neih loh en turin pressure button chu hmet la , leh input a awm loh chuan total pressure point-in output a nei em tih leh input a awm loh chuan ,Pressing button connect-in computer a thawk tha em tih enfiah rawh. Input a awm a, computer-in output a neih loh emaw, a hnunglam kawngkhar a khar loh emaw, a hnung lam kawngkhar chu a ni lo emaw, a hnung lam kawngkhar chu a khar tur a ni lo.
3) Electric proportional plate atanga oil valve line thlenga output chu normal a nih leh nih loh enfiah rawh.Electric proportional coil normal. a ni.
4) Pressure dial chu a normal em tih enfiah rawh .
