Usage tips chungchang chipchiar taka sawifiahna .
I. Sandblasting tank hman hmaa inbuatsaihna .
Sandblasting tank enfiahna atana hman tur panga-Step hman dan
Pipelines leh Joints: Air hose, sandblasting pipe, leh joint zawng zawng te chu a chhe, a leak, emaw, a lo chhuahna tur emaw enfiah tur a ni.
Tank Body and Seal: Tank body-ah hian a chhe tawh leh awm loh enfiah la, sealing rings (a bik takin a hnuai lam cover-a awmte) chu a dik lo, a fai leh a dah dik em tih finfiah rawh. Hei hi boruak leh sand leakage venna kawng pawimawh tak a ni.
Valves leh controllers: Exhaust valve, intake valve leh sand discharge valve te chu a awlsam zawngin an thawk em tih enfiah tur a ni. Remote control (a awm chuan) a thawk tha em tih enfiah rawh.
Nozzle: Nozzle-a wear condition awm leh awm loh enfiah rawh. Severe wear (enlarged inner holes or out-of-roundness) hian tihfai thatna leh boruak pressure nasa takin a ti tlem ang. A tlangpuiin hole diameter original aiin a let 1.5-a a chhe chuan thlak tur a ni.
Abrasive: Abrasives dry, fai leh a size dik tak (steel shot, glass beads, brown corundum, etc. ang chi) hmang rawh. Damp abrasives hian clogging leh hardening a thlen thei.
Loading leh pressurization dik tak .
Gas source off: Main intake valve chu closed position-ah a awm ngei ngei tur a ni.
Safety Pressure Relief: Sandblasting tank chhunga pressure awm chu chhuah tir turin exhaust valve chu hawng la.
Loading: Feeding cover chu hawng la, abrasive chu rated capacity 70%-80% ah load rawh (compressed air tan hmun kalsan rawh). Loading zawhah sealing cover chu a tight dik em tih enfiah tur a ni.
Establish pressure: A hmasa berin exhaust valve kha khar la, chutah chuan main intake valve chu zawi zawiin hawng la, tank chhunga pressure chu working pressure thlengin zawi zawiin hawng rawh.
II a ni. Assignment neih chhunga hnathawh dan .
Angle leh distance tha ber ber vawng reng rawh .
Angle: Rust removal leh paint removal atan chuan nozzle leh working surface inkar angle chu 70℃atanga 80℃a tha ber. Reinforcement atan chuan process requirements (a tlangpuiin vertical hnaih ber) angin kalpui tur a ni.
A hlat zawng: A tlangpuiin centimetre 15 atanga 30 vel a awm thin. A hnaih lutuk chuan awlsam takin substrate leh nozzle a tichhia thei a, a hla lutuk chuan efficiency hniam tak a thlen thei bawk. Over-spraying emaw hmun thenkhata tihfai tlem emaw a nih loh nan speed constant-in kal zel ang che.
Pressure leh flow control .
Workpiece material, abrasive chi leh tihfai ngai ang zelin pressure chu a level dik takah siamrem rawh. Pressure a san chuan a tha zawk tihna a ni lo. Pressure tam lutuk avanga rebound awm chu a na zawk ang.
Abrasive flow rate hi remote control emaw sand discharge valve hmangin control theih a ni a, chu chuan uniform cleaning effect a nei thei a ni.
Clogging venna atana hman tur tips .
Abrasive chu a vawt reng thin.
Sandblasting tank chuan a hnathawh laiin sand a discharge nghal a nih chuan, sand discharge valve chu khar hmasa la, chutah chuan sandblasting pipe chu tlem han nghat la emaw, tank taksa chu zawi zawiin tap la, "sand bridge" lo awm thei chu thehdarh tum rawh.
A hlawhtling lo a nih chuan, safety procedure angin depressurizing hnuah enfiah leh rawh.
Real-Hun hun enfiahna .
Faina nghawng leh leivut dinhmun enfiah chu ngaihven rawh. Performance tha lo chu nozzle wear vang emaw, pressure tlem vang emaw, abrasive thianghlim lo vang emaw pawh a ni thei.
Device aw ri chu ngaithla rawh. Noise pangngai lo chuan gas leak emaw, internal component a chhiat emaw tih a tilang thei.
iii a ni. Post-Operation enkawl dan tur .
Pressure him taka tihdam leh tank tihfai .
Operation zawh hnuah sand discharge valve leh main air intake valve kha khar hmasa phawt ang che.
Exhaust valve chu hawng la, tank chhunga pressure awm zawng zawng chu chhuah vek rawh (pressure gauge chu zero-ah dah leh rawh).
Pressure a awm loh thu an nemnghet hnuah feeding cover chu hawng la, residual abrasive leh tank chhungah leivut chu tifai rawh. A bik takin khaw lum laiin abrasive hi empty a pawimawh hle.
Faina leh enkawl dan .
Filter screen chu tifai la, sealing surface leh vent holes te chu tifai rawh.
A vulnerable part zawng zawng (nozzle, sealing ring, sandblasting pipe) te wear condition enfiah la, a hun takah thlak rawh.
Thil hmanrua te chu hmun vawt leh thianghlim takah dah tur a ni.
Chhinchhiah
Sandblasting tank hman hun leh a thlak danglam parts dinhmun te chu predictive maintenance awlsam zawk nan record rawh.
Thiamna leh thurawn sang tak .
Abrasive selection: Workpiece (aluminum, steel, composite material) leh a mamawh surface roughness (SA value) a zirin abrasive chi leh particle size dik tak thlang rawh.
Nozzle thlan dan: Venturi type nozzle hi straight hole type aiin a tha zawk. Boron carbide/tungsten carbide nozzle hian ceramic nozzle aiin an dam rei zawk hle a, mahse a man a to zawk bawk.
Teamwork: Hmun zau takah hna kan thawh hian pahnih pahnih in hnathawh a ngai a, in enkawl a ngai bawk.
Environment Protection and Recycling: Conditions in a phal chuan abrasive recycling leh sorting system chu abrasives recycle turin configure tur a ni a, cost a tlem a, leivut a tlem thei bawk.
Summary: Shot blasting tank hman tangkai leh him taka hman hi "inbuatsaihna tha tak, standardized operation leh strict maintenance" ah a innghat a ni. Safety dah pawimawh fo a, sandblasting tank hman dan tur khauh taka zawm reng mai chauh hian hnathawh chu a kal zel dan tur dik tak kan enfiah thei ang a, lei chunglam enkawlna effect duh ang kan hmu thei ang. Thil hmanrua model bikte chu a official operation manual en ngei ngei tur a ni.
