Differential Pressure Gauge

Local‑mounted indicating instrument for measuring pressure difference between two process points. Available in mechanical pointer‑type and digital‑display variants. It provides direct differential‑pressure readouts without additional calculation, and is deployed within dust‑removal & filtration systems to monitor filter‑resistance variations.

Filter Cage (Bag Cage)

Support component for baghouse dust collectors. Installed inside polyester needle‑felt filter bags to support and maintain cylindrical filter‑bag geometry and prevent filter‑bag collapse induced by negative pressure. Used together with pulse‑jet cleaning systems and widely adopted in corn dust‑removal equipment.

Dust Collector Filter Bag (Polyester Needle-Punched Felt)

Core filter element for pulse‑jet baghouse dust collectors. Manufactured from polyester staple‑fiber via needle‑punched process and sewn into bag assemblies, used matched with filter cages. Within corn dust‑removal systems, it intercepts corn dust and husk fragments in process airflow to achieve gas‑solid separation and meet exhaust‑gas emission requirements. It is a critical consumable spare‑part for grain‑dust‑handling equipment.

Explosion Vent

Safety pressure‑relief device for dust‑removal and powder‑processing equipment. Mainly fitted for bag‑house filters, cyclone separators and storage silos. When internal dust‑explosion overpressure occurs, the vent opens rapidly at pre‑set pressure to discharge explosion shock‑waves and high‑temperature flue‑gas. It protects equipment housings from rupture and mitigates personnel‑injury risk as well as secondary‑explosion hazards.

Fan impeller

Core rotating component for dust‑removal induced‑draft fans. Assembled via welding of hub, blades and back‑plate, and fitted to the fan main shaft. During high‑speed rotation it imparts momentum to process airflow, generating negative pressure for corn dust‑removal systems, drawing dust‑laden workshop gas and stabilizing airflow throughout full dust‑removal piping. It is the core power‑generating spare‑part for dust‑removal circuits.

Controller

Core electrical control component for bag‑house / cartridge dust collectors. Sequentially triggers electromagnetic pulse‑jet valves for cyclic blow‑off to complete automatic filter‑bag cleaning. Maintains stable dust‑collector differential‑pressure and nominal dust‑removal efficiency. Popular series: QYM, DMK, TKZM. Output channels: 1‑36 configurable. Input AC 220 V; output DC 24 V / AC 220 V. Control modes available: time‑based control, differential‑pressure intelligent control, on‑line cleaning, off‑line compartment cleaning (with lifting valves).

Pulse‑Jet Valve

Critical pneumatic blow‑off component for pulse‑jet bag‑house dust collectors. Deployed together with filter bags and control instruments and known as the

Venturi tube

Fluid‑dynamic component named after physicist Giovanni Battista Venturi. Operates per Venturi effect (Bernoulli’s principle): As fluid flows through variable‑cross‑section piping, reduced‑cross‑section accelerates flow‑velocity and lowers static‑pressure forming negative‑pressure suction zone; downstream pipe‑section expands again, flow‑velocity decreases and static‑pressure partially recovers.

Rotary Airlock Valve (Ash Discharge Valve)

Core dust‑removal‑system component, normally vertically mounted at dust‑collector hopper bottoms. It continuously discharges dust particulate while isolating internal‑external air‑pressure to prevent air‑ingress leakage and preserve dust‑collector negative‑pressure operating conditions. Common models: YJD‑A (square‑flange), YJD‑B (round‑flange). Material options: cast‑iron, carbon‑steel, 304 stainless‑steel; special variants include explosion‑proof and high‑temperature chain‑drive execution.

Compressed Air Hose

Flexible pipeline element within pneumatic‑systems for conveying pressurized compressed‑air. Interconnects air compressors, air‑source‑treatment assemblies, valves and pneumatic equipment / actuators. Fundamental component of pneumatic circuits for dust‑removal, chemical‑processing and general production‑lines.
