The exceptional performance of rotary pumps begins with meticulous attention on the assembly bench.Every step in the process directly determines the final product’s efficiency and lifespan.
All components—shafts,rotors,pump bodies,and end covers—must be thoroughly cleansed of oil residue,chips,and microscopic burrs before assembly.Any residual impurities jeopardize the pump’s service life and pose a threat to precision machinery.

High-precision bearings:Whether installed via cold-pressing or thermal-fitting,the goal remains unwavering:to mount bearings with utmost accuracy onto shafts and within end covers or pump bodies.Proper preload or clearance is the foundation for long-term,stable bearing operation.
Rotor installation:The main shaft is positioned first,followed by the careful placement of conjugate rotor pairs.This phase demands absolute precision in meshing phase alignment—secured by keys,splines,or precision dowel pins.Post-installation,meshing gaps between rotors and axial/radial clearances against pump bodies or end covers must be rigorously verified using feeler gauges to ensure smooth operation.

Pump body and end cover assembly:Alignment pins establish critical positioning.During closure,rotor surfaces and sealing faces must be protected from damage.Bolts are tightened in strict sequence with specified torque values to prevent deformation and maintain geometric integrity.
Sealing system assembly:Mechanical seals or packing seals are then installed,with compression or spring preload calibrated to exact specifications.This micro-tension forms a vital barrier against leakage and safeguards internal cleanliness.
Final accessory integration:Bearing caps,seal covers,couplings,protective shrouds,and temperature/pressure sensors are systematically mounted.These components collectively enhance functionality and monitor operational health.
