FAQ
1. What is the primary function of this rack & pinion system?
Designed for automated greenhouse ventilation and shading, this system converts rotary motion (from motors or manual cranks) into linear motion to open/close vents or retract shade nets with precision.
2. What materials are used, and why?
Stainless steel (304/316) or aluminum alloy – Offers corrosion resistance for humid greenhouse environments. Surface treatments (anodizing, powder coating) further enhance durability.
3. Can the system be customized for my greenhouse dimensions?
Yes. We provide:
Custom rack lengths (up to 6m or longer with splicing).
Adjustable gear modules (1.0–2.0mm) for varying load requirements.
Motor/actuator compatibility (electric, pneumatic, or manual drives).
4. What’s the load capacity, and how is it calculated?
Standard capacity: 500–2000N (depends on gear module and material).
We perform FEA simulations to verify load-bearing capacity for your specific application.
5. How do I maintain the system?
Minimal maintenance required:
Lubrication-free designs available (optional self-lubricating coatings).
Periodic inspection for debris (recommended cleaning with dry air/brush).
6. What’s the lifespan of the system?
10+ years under normal conditions (UV-resistant coatings extend longevity). Lifespan depends on:
Environmental exposure (coastal/high-salinity areas may require SS316).
Load cycles (we provide cycle-life estimates upon request).
7. Is the system compatible with smart greenhouse controls?
Yes. Integrates with:
PLC systems (via motorized actuators).
Limit switches (for automated position feedback).
IoT sensors (optional retrofitting).
8. What certifications do you offer?
ISO 9001 (quality management), RoHS (material safety), and IP54/IP65 (weatherproofing). CE certification available upon request.
9. What’s your lead time for custom orders?
30–45 days (standard).
