Design, fabrication, installation and full environmental compliance for the new pump frame welding line at Honda's Liangjiang New Area plant — from explosion-proof capture worktops to a code-compliant stack with sampling platform, delivered and accepted within 50 days.
Honda's new pump frame line pairs one grinding station with one robot welding cell. We supplied the complete air-pollution control package plus the surrounding plant infrastructure:
Every guarantee was written into the contract — and verified by third-party monitoring at acceptance:
| Guarantee | Committed Value |
|---|---|
| Fume capture efficiency | ≥ 90% (negative pressure, interlocked) |
| Dust removal efficiency | ≥ 95% at the collector |
| Stack emission | DB 50/418-2016 limit − 30% margin |
| Total system power | ≤ 20 kW (VFD fan) |
| Delivery & commissioning | 50 days from contract signing |
Welding fume particles are 0.1–1.25 µm — half of it iron oxide, plus manganese dioxide and silica that cause welder pneumoconiosis. Sticky, oily fume is exactly what blinds ordinary filters, so the train is engineered around that reality.
Explosion-proof dual-station worktops and large capture hoods keep fume out of the welder's breathing zone. Dampers balance airflow across stations; the system starts and stops together with the line.
A stainless-steel mesh demister box ahead of the collector traps welding sparks and oily aerosol — protecting the cartridges from both fire risk and blinding.
Donaldson-type vertical pleated cartridges (Ø350 × 660 mm, 7–8 m² each) with flame-retardant media rated to 150 °C, 0.5–1.0 µm filtration and ≤ 45 Pa initial resistance. PLC-programmed pulse cleaning; carbon steel housing with explosion vent panel.
Downstream variable-frequency fan (negative-pressure layout keeps ductwork leak-free) with soft-start, overload, over-temperature and fire interlocks; e-stop buttons at the cabinet and every operator station.
Galvanized stack on a carbon-steel tower with code-compliant sampling platform, yellow-guarded safe access, and C25 concrete foundation (7,000 × 3,000 × 200 mm) — ready for third-party monitoring from day one.
We also delivered the catalytic combustion (RCO) adsorption–desorption train for Honda's organic exhaust stream — same works, same quality standard, installed and commissioned by our own crews.
Buying a collector is easy — getting the line legally operational is not. For Honda we ran the entire compliance track in parallel with manufacturing:
August 2026: welding line and purification system in operation. November 2026: high-emission stacks with sampling platforms on the plant roof. Our factory photos show the RCO train before shipment.
We deliver the equipment, the infrastructure and the permits — one contractor, one acceptance test. Tell us your line layout for a written proposal within 24 hours.
