Brand: SOLH by Richge Technology | Full Mechanical & Interface Interchangeable with SMC ZL1 Original Series
 |
SOLIH ZL1‑series adopts multi‑stage diffuser venturi energy‑saving vacuum ejector structure, fully interchangeable with SMC ZL1 original dimension and port layout. Under identical air consumption condition, it delivers higher suction flow and lower energy loss. Widely deployed for high‑speed pick‑and‑place robot manipulators and strong adsorption applications for porous breathable workpieces.
Two core configurations for selection:
• Valveless Type (Without valve): Pure ejector body only, controlled by external solenoid valves. Low‑cost and highly flexible for custom system integration.
• With‑Valve Type: Integrated supply valve, release valve and vacuum pressure detection module. No extra external valve components required, simplified piping and faster response. Preferred mainstream solution for robot end‑of‑arm tooling (EOAT).
Model 12A specification: Max suction flow 100 L/min (ANR), working supply air pressure 0.4~0.6 MPa clean compressed air. Supply port and vacuum port equipped with one‑touch fittings: Φ6 metric or Φ1/2‑inch imperial optional.

Solution 1: Valveless Cost‑Optimized Circuit
AFC2000 non‑oil two‑unit air source treatment → 3V110 3‑way solenoid valve → ZL1‑12A valveless vacuum ejector → ZPT vacuum suction cup
Solution 2: With‑Valve High‑Speed Robot Pick‑and‑Place Circuit
AR pressure regulator → ZL1‑12A‑K15MZ‑DAML (integrated supply valve, release valve & vacuum pressure switch) → robot end‑effector suction cup, automatic missing‑workpiece alarm function supported.
Solution 3: Multi‑Bank Centralized Air Supply Circuit
AFC large‑flow non‑oil two‑unit → multiple ZL1 with‑valve ejector manifold assembly → multi‑suction‑cup synchronous material picking.
• Port size: For standard PU6 / Φ6 tubing, select no‑mark metric port. For imperial Φ1/2" tubing, specify imperial port together with inHg / psi pressure unit.
• Exhaust: For low‑noise workshop environment, keep standard silencer exhaust. For exhausting to designated safe area, adopt PR / PG / PN port‑type centralized exhaust.
• Voltage: DC24V(code 5) for domestic automation equipment; DC12V / DC6V for European export or low‑voltage‑device projects.
• Valve combination: K1 (N.C. supply + N.C. release) for standard high‑speed pick‑and‑place; K2 for cost‑reduction; B1/B2 for special normally‑open vacuum‑holding working conditions.
• Detection requirement: Choose D vacuum pressure switch(NPN/PNP match PLC input type) for PLC missing‑part alarm; G local pressure gauge for on‑site visual inspection; GN detection port for third‑party external data acquisition.
• Indicator & Surge‑protection: Select Z / U version for cabinet diagnostic indication; S over‑voltage‑protection for humid harsh working environment.
• Manual override: Choose D push‑turn locking manual‑override for frequent commissioning & debugging scenarios, support locked continuous air supply.
• 3C electronics PCB & chip high‑speed pick‑and‑place handling
• Lithium‑ion battery electrode sheet material transfer
• Carton & porous‑material strong‑force adsorption
• Glass & sheet‑metal heavy‑duty robotic picking
• Injection‑molding robot part removal & demolding
• Food‑processing packaging grabbing application
• Logistics sorting high‑speed robotic transfer systems
• Do NOT use oil‑mist FRL units (AC / BC series three‑unit) for vacuum ejector air supply. Lubrication oil will clog multi‑stage diffuser nozzles, must adopt AFC non‑oil two‑unit air‑source treatment unit.
• Mandatorily install ZFC inline vacuum filter on upstream side. Tiny multi‑stage nozzles are sensitive to dust; suction flow will degrade heavily once clogged by particle contamination.
• Keep hose length between ejector and suction cup as short as possible to guarantee fast vacuum build‑up and stable suction performance.
• Optimal supply air pressure range 0.4~0.6 MPa. Insufficient pressure leads to weak suction; excessive pressure increases compressed‑air consumption.
• For with‑valve models, select Z / S / U versions with built‑in surge‑protection circuit to extend solenoid coil service life inside control cabinets.
• For PR / PG / PN centralized exhaust configurations, maintain unobstructed exhaust piping, back‑pressure will severely degrade vacuum‑building performance.
