CENTRIGUGAL PUMP HAVING ADJUSTABLE CLEAN-OUT ASSEMBLY |
摘要 |
<p>A centrifugal pump having an adjustable clean-out assembly ( 60 ), the position of which determines the face clearance between a wear plate ( 72 ) and an impeller ( 20 ). The clean-out assembly includes an end cover ( 63 ) that threadedly mounts a plurality of adjustment assemblies. The adjustment assembly includes an adjuster ( 104 ) that defines a through bore for slidably receiving a retaining stud ( 66 ) that extends from the pump housing. Each adjuster includes an abutment surface ( 108 ) which engages a pump surface and which establishes the face clearance between the wear plate and the impeller. Each adjuster includes a hex-shaped head which is engageable by an associated locking member ( 120 ) secured to the end cover. Each locking member includes a locking collar ( 120 a) having 18 teeth which allows the collar to engage the hex-shaped head of the adjuster in 18 different postions. By knowing the thread pitch of the adjuster thread, precise rotations of the adjuster can be used to establish a precise clearance between the wear plate and impeller. Once the adjustment is made, the locking collar is secured to the end cover which enables the clean-out assembly to be removed from the pump without disturbing the adjustment.</p> |
