Venturi trim handling systems and material educators

Yangzhong Lingxin / Lingxin Fan venturi pneumatic trim handling units transport continuous edge ribbons of paper, foil, and laminate films without shredding. High-velocity air induction prevents ribbon snapping and ensures jam-free movement directly into waste compaction areas.

Continuous ribbon evacuation for delicate papers, aluminum foil, and plastic webs
Adjustable annular venturi nozzles for calibrated motive air volume regulation
Non-contact interior path eliminating moving mechanisms within material airstream
Selection of venturi nozzles, induction bodies, and ducts from model specifications

Fluoroplastic seals and engineering PTFE polymer components

Yangzhong Lingxin / Lingxin Fan anti-corrosion components machined from virgin PTFE, polyurethane, and engineering polyamides serve paper machinery and chemical processes. Excellent chemical inertness and low friction coefficients protect equipment journals from corrosive media.

Continuous service temperature range from -190 to +250 degrees Celsius
Precision machining of polymer bushings, guide rings, seals, and scraper blades
Inertness against industrial acids, alkalis, and cellulose chemical solutions
Custom fabrication of gaskets, valve seats, and guide rolls to component drawings

Aerodynamic design and dynamic balancing of ZXFC trim chopper fans

When designing pneumatic duct systems for corrugated edge ribbons, required airflow of the Yangzhong Lingxin / Lingxin Fan ZXFC series chopper fan is calculated from line web speed and trim ribbon dimensions.

To prevent material jamming in transport ducts, conveying air velocity is maintained above 22 to 26 meters per second. The heavy-duty rotor with radial blades and cutting tools undergoes precision balancing under ISO 1940 grade G2.5 guidelines.

During routine operation, cutting edges of the rotating and stationary knives are inspected every 500 operating hours. The shearing clearance between blades is calibrated between 0.2 and 0.4 mm using precision shims.

Proper knife alignment prevents jamming of thin papers and protects heavy-duty bearing housings from unwanted vibration and mechanical fatigue.

Installation of ZQFL cyclones and air-material separators

Yangzhong Lingxin / Lingxin Fan ZQFL series cyclone separators are installed directly above feed chutes of automated horizontal baling presses.

The duct route leading into the tangential intake nozzle requires a straight run of at least 3 to 5 hydraulic diameters to stabilize internal vortex swirling.

Interior wear baffles fabricated from hardened structural steel absorb kinetic impact of incoming trims and guide them smoothly into the bottom drop cone.

To eliminate ambient air leakage into the negative pressure separator shell, an airtight rotary drum discharge valve with polyurethane flexible tips is mounted beneath the discharge flange.

Preventative maintenance includes checking flange gasket integrity and inspecting replaceable wear-resistant steel liners located directly along primary high-velocity impact zones.

Maintenance protocol for ZM series pulse jet bag collectors

Yangzhong Lingxin / Lingxin Fan ZM series pulse jet bag filters capture fine paper fibers and suspended dust particles before clean air is recirculated or exhausted into the plant. Compressed air pressure inside the pulse cleaning header is maintained between 0.5 and 0.7 MPa.

An electronic timing sequencer cyclically fires diaphragm solenoid valves, injecting short air bursts into individual filter bags through venturi nozzles.

Prior to system startup, tensioning of filter bags on supporting wire cages is verified to prevent fabric chafing.

A differential pressure gauge continuously measures resistance across the filter media: when differential head exceeds 1500 Pa, manual pulse cleaning is triggered or filter bags are scheduled for routine replacement.

Acoustic dampening and mounting of XSQ industrial mufflers

Yangzhong Lingxin / Lingxin Fan XSQ series industrial silencers are installed on suction and discharge ports of high-velocity chopper fans to attenuate aerodynamic blade passing frequencies.

The silencer body is connected to plant ductwork using flexible heat-resistant fabric expansion joints, acoustically isolating fan vibrations from ceiling trusses and building structures.

Sound-absorbing mineral wool splitters inside the unit are protected by perforated galvanized steel covers and glass fiber cloth membranes, preventing fiber migration into airstreams moving up to 30 meters per second.

Maintenance involves inspecting acoustic splitter alignment and removing paper fuzz from internal perforations.

Tuning and operation of venturi continuous ribbon educators

Yangzhong Lingxin / Lingxin Fan venturi trim inductors are utilized on slitter-rewinders and film slitters to evacuate continuous edge ribbons without mechanical chop.

Motive air supplied by high-pressure centrifugal blowers enters an annular perimeter nozzle, generating strong suction in the intake throat without physical contact with the continuous ribbon.

Motive air flow rate is adjusted via a graduated throttle damper mechanism. Matching intake air velocity with slitting line speed guarantees stable ribbon feeding without tensile twisting or ribbon snapping during high-speed rewinder operations reaching up to 600 to 800 meters per minute.

Operation of PTFE polymer seals and machine components

Yangzhong Lingxin / Lingxin Fan fluoroplastic bushings, guide rings, and seals are installed in mechanical assemblies exposed to aggressive chemicals and humid pulp slurries.

Due to its minimal dry friction coefficient, virgin PTFE prevents shaft scoring and operates without lubricating greases, preventing oil contamination of finished paper webs.

When installing polymer parts, thermal expansion allowances are provided to compensate for the thermal expansion coefficient of fluoroplastic compared to structural steel.

Bushing press-fitting requires concentric alignment checks, while wear strips are secured with flush stainless steel fasteners tightened to specified torque values.
