I.Product Overview:High Efficiency Conveying Equipment Based on Positive Displacement Principle

Bonve Pump Industry’s cam rotor pump,a representative positive displacement pump,achieves directional fluid transfer through the periodic volume changes in the pump chamber caused by the non contact meshing movement of dual rotors.The equipment consists of a drive system,pump head assembly,and control system.The pump head,as the core fluid handling component,integrates the pump body,rotors,shaft system,sealing devices,and bearing assemblies.During operation,symmetrically arranged cam rotors rotate in opposite directions under synchronized gear drive:the expanding volume of the suction chamber creates negative pressure to draw in the medium,which is then compressed and discharged as the rotors rotate into the meshing zone.

The device features three core technical characteristics:

1.Non contact rotor design maintains uniform clearance between rotors,reducing friction loss while enabling the handling of media containing solid particles.

2.Rotor profiles(cycloidal or involute)ensure linear volume changes in the pump chamber,delivering low pulsation flow output.

3.Optimized rotor center distance and pump body flow channel structure provide robust self priming capability,allowing quick startup without auxiliary priming.These features make it suitable for complex applications such as wastewater treatment,food processing,and petrochemical industries.

II.Pump Head Structure:Engineering Implementation of a Precision Mechanical System

The cam rotor pump head from Bonve Pump Industry adopts a modular design,with components working synergistically to ensure efficient operation:

· Pump body:Constructed from gray cast iron or stainless steel,formed through precision casting and CNC machining.Its horizontal dual support or vertical suspended structure ensures shaft stability,compatible with inlet/outlet flanges of various diameters.

· Rotors:Two or three lobe symmetric cam rotors,made of wear resistant alloys or corrosion resistant stainless steel,undergo high precision grinding.Their profiles enable reverse synchronized rotation via hardened and tempered synchronized gears.Torque transmission is secured through involute splines or interference fits.

· Shaft system:Forged from premium alloy steel,heat treated for enhanced rigidity,and paired with high precision rolling or sliding bearings.

Sealing system:Standard dual face balanced mechanical seals with silicon carbide/carbon graphite pairs,adaptable to varying media temperatures.Sanitary grade seals compliant with 3 A standards are available for food grade applications.

Lubrication:Grease or oil lubrication selected based on rotational speed,with integrated lubrication channels and temperature monitoring interfaces in bearing housings.

Additional features include:

· Integrated bearing housings and pump body casting for radial/axial load capacity.

· Elastic couplings compensating for minor misalignments between motor and drive shaft.

· Splash lubricated synchronized gearbox with protective breather valves.

· Removable inspection ports and vent holes for maintenance and monitoring.

III.Pump Head Details:Engineering Analysis of Modular Architecture

Bonve Pump Industry decomposes the pump head into three functional modules for structural transparency and maintenance efficiency:

1.Fluid handling core module:

Pump body with optimized dual spiral flow channels to minimize flow resistance.

· Adjustable rotor center distance compensating for wear.

· Precision ground end cover sealing surfaces ensuring airtightness.

· Enlarged inlet flange design enhancing suction efficiency and reducing cavitation risks.

2.Power transmission module:

· Chrome plated drive shaft with vibration absorbing elastic couplings.
