ZH‑D Series Body‑Ported Vacuum Ejector

ZH‑D Series Body‑Ported Vacuum Ejector | Single‑Stage Venturi Direct Pneumatic Connection Vacuum Generator

Brand: SOLH by Richge Technology | Full Mechanical Interchangeable with Imported ZH Series Vacuum Generator

1. Product Overview

     ZH‑D body‑ported type is single‑stage venturi vacuum ejector. Three independent ports including SUP supply port, VAC vacuum port and EXH exhaust port require external piping. No built‑in silencer inside main body. Compact and lightweight design with integrated resin nozzle structure, fully interchangeable with imported ZH series.

  Model Distinction

     • ZH‑D Body‑ported type: Three ports for external piping, without built‑in silencer.

     • ZH‑B Box‑type: Equipped with integrated silencer inside body, only supply and vacuum ports reserved.

  Two performance grades:

     • S‑specification (High‑vacuum): Ultimate vacuum ‑90kPa, ideal for sealed smooth workpieces.

     • L‑specification (High‑flow): Larger suction flow with lower vacuum level, for breathable porous workpieces such as paper, fabric and carton.

  Nozzle bore covers Φ0.5 / 0.7 /1.0 /1.3 /1.5 /1.8 /2.0 mm. Support multiple connection options: one‑touch fitting, G/Rc thread, NPT imperial thread. Multiple mounting solutions: direct screw fastening, mounting bracket and DIN rail installation. Widely applied for robot end effector and multi‑station module applications.

2. Complete Model Coding Explanation

Example model: ZH10DSA‑06‑08‑10

     • ZH: Series code of vacuum ejector

     • 10: Nozzle bore code

     • D / B: Body form. D = body‑ported type with 3 external ports without built‑in silencer; B = box‑type with integrated silencer

     • S / L: Vacuum characteristic. S = high‑vacuum type ultimate ‑90 kPa with moderate suction flow; L = high‑flow type. ZH05‑13 ultimate ‑48 kPa; ZH15‑20 ultimate ‑66 kPa, large flow for breathable workpieces

     • A: New‑generation lightweight version with shortened dimension and reduced weight

     • ‑06‑08‑10: Port specification (SUP‑VAC‑EXH). Two‑digit number stands for metric one‑touch fitting size(06=Φ6,08=Φ8,10=Φ10,12=Φ12). F01/F02/F03 for G/Rc thread; N01/N02 for NPT imperial thread.

  Order example: ZH13DSA‑08‑10‑10
     ZH body‑ported vacuum ejector, Φ1.3 mm nozzle, S high‑vacuum grade, new A lightweight version; supply port Φ8, vacuum port Φ10, exhaust port Φ10 one‑touch fitting.

3. Core Performance Advantages

     • Three fully independent external ports: Separate SUP supply, VAC vacuum and EXH exhaust ports. Exhaust gas can connect external silencer or centralized exhaust pipeline. Suitable for robot end effector and module integration, free from internal silencer space constraints.

     • Lightweight integrated resin nozzle: Nozzle and main body integrally molded for remarkable weight reduction, perfect for high‑speed moving EOAT. New A version shortens length and height, weight reduced up to 74%.

     • Dual vacuum performance options: S high‑vacuum for smooth sealed workpieces including glass, metal sheet and plastic housing; L high‑flow for carton, film, fabric and leak‑prone materials for leakage compensation.

     • Rich port selections: Metric one‑touch fitting, G/Rc pipe thread and NPT imperial thread for global‑market equipment adaptation.

     • Diversified mounting methods: Direct screw fastening, standard bracket, L‑shaped bracket and DIN rail mounting for flexible layout.

     • Oil‑free operation requirement: Oil‑mist lubrication is forbidden, only dry filtered compressed air is required.

4. Standard Technical Specifications

Performance at 0.5 MPa supply pressure (ANR)

For L‑high‑flow variant: higher suction flow under identical nozzle bore with lower ultimate vacuum level.

6. Step‑by‑Step Selection Guidance

     • S / L performance selection

 ￮ ✅ S high‑vacuum (‑90 kPa): Smooth sealed workpieces such as steel plate, glass, plastic housing, PCB; minor leakage, high adsorption force required.

 ￮ ✅ L high‑flow: Carton, foam, film, fabric and other leak‑prone breathable workpieces, large flow compensates vacuum leakage.

     • Nozzle bore selection: Select according to total suction‑cup adsorption area. Larger nozzle brings higher suction flow meanwhile higher air consumption. Avoid over‑sized nozzle to prevent compressed‑air waste.

     • Port type selection: Metric one‑touch fitting (06/08/10/12) for domestic automation equipment; G thread / NPT thread for overseas export machines.

     • Exhaust handling note for D‑type: D‑variant has no built‑in silencer. EXH exhaust port must connect external silencer otherwise noise will be extreme; or route exhaust pipe out of equipment cabinet.

     • Vacuum detection solution: ZH series vacuum ejector without built‑in pressure switch. Add external ZSE vacuum pressure switch if signal feedback is needed.

7. Typical Application Scenarios

     • Robot EOAT end‑of‑arm picking: 3C plastic parts, PCB and battery sheet handling

     • Packaging industry: carton, film and paper material pick‑up

     • Small‑size part demolding for injection‑molding robot

     • Multi‑parallel vacuum module for multi‑suction‑cup synchronous adsorption

     • Automation stations requiring centralized waste‑gas exhaust outside equipment housing

8. Standard Pneumatic Circuit Diagram Description

     ZH‑D body‑ported standard circuit: AFC air‑source filter (oil‑mist unit forbidden) → 3/2 solenoid valve → SUP supply port of ZH‑D; VAC vacuum port connects ZFC vacuum filter then to suction cup; EXH exhaust port connects external silencer or exhaust hose routed outside equipment.

9. Important Operation Notes

     • Oil‑mist lubricator is strictly prohibited. Oil contaminant will clog tiny nozzle orifice, cause suction‑force decay or complete failure. Only air filter shall be adopted for air source treatment.

     • ZFC inline vacuum filter must be installed on vacuum side. Dust particle ingress will lead to nozzle blockage.

     • For ZH‑D body‑ported ejector, EXH exhaust port must equip silencer to avoid excessive noise level.

     • Recommended supply pressure:0.4‑0.5 MPa. Long‑term continuous operation under full 0.6 MPa is not suggested.

     • Minimize hose length between vacuum ejector and suction cup, reduce pipeline volume for faster vacuum response.
