Title:
ADJUSTMENT APPARATUS AND ADJUSTMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2024/061291
Kind Code:
A1
Abstract:
An adjustment apparatus, for use in adjusting a rotating speed sensor (4) of a main pump spindle (2). A probe (1) is arranged on the outer wall surface of the main pump spindle (2). A sensing groove (41) penetrating in the circumferential direction is formed in the end of the rotating speed sensor (4) opposite to the main pump spindle (2). The sensing groove (41) is used for the probe (1) to rotate through. The adjustment apparatus comprises a mounting bracket (5) arranged on a main pump housing and used for mounting the rotating speed sensor (4); and a probe simulator (32) comprising a positioning head (B) for positioning the probe (1) and a measurement assembly (324), wherein the positioning head (B) rotates to pass through the sensing groove (41), and the measurement assembly (324) is used for acquiring a distance between the positioning head (B) and the axial inner side wall of the sensing groove (41) and a distance between the positioning head (B) and the radial bottom wall of the sensing groove (41). The position of the rotating speed sensor (4) on the mounting bracket (5) is adjustable, the position of the rotating speed sensor relative to the probe (1) and a positioning member (321) can be adjusted, the accurate relative position between the rotating speed sensor (4) and the probe (1) is guaranteed, and normal rotating speed detection of the rotating speed sensor (4) on the probe (1) is achieved. Also provided is an adjustment method.
