Embodiment Construction

[0008] Rotate the two couplings of the water pump and the motor at 0°, 90°, 180°, and 270°, and measure the axial clearance b values ​​at 4 positions at the same time. The axial clearance is b 1 -b 3 or b 2 -b 4 . (SL317-2004) "Code for Installation and Acceptance of Pumping Stations" requires that the axial clearance of rigid couplings should not be greater than 0.05-0.08mm, and the axial clearance of elastic couplings should not be greater than 0.08-0.15mm. Otherwise, the axial clearance of the pump unit needs to be adjusted.

[0009] Such as figure 1 Add and subtract the thickness of the gasket at the front and rear anchor bolts of the shown motor, or the movement value of the left and right moving motors is calculated according to formula (1) and formula (2) according to the principle of similar triangles.

Abstract

Provided is an axial clearance adjustment method for a pumping unit. According to a measurement result of an axial clearance, the sizes, supposed to be obtained after measurement, of a front anchor and a rear anchor of a motor are calculated accurately and quickly, that is to say, the thicknesses of pads which need to be added to or removed from a front anchor bolt and a rear anchor bolt of the motor are worked out, the axial clearance can meet the installation accuracy requirement, the installation quality of the pumping unit is guaranteed, and the installation progress is accelerated.

Description

1. Technical field [0001] The invention relates to the adjustment of the axial clearance of the water pump unit, especially the adjustment of the axial clearance of the two shaft couplings of the water pump and the motor. The shafts are parallel and concentric, and the two axes of the water pump and the motor are on the same straight line to ensure the smooth and safe operation of the unit. 2. Background technology [0002] Water pump units are widely used in farmland irrigation and drainage, urban water supply and drainage, water supply and drainage of industrial and mining enterprises and institutions, and play a decisive role in high and stable agricultural production; provide reliable guarantee for the production and life of urban residents, industrial and mining, enterprises and institutions. The installation quality of the water pump unit not only directly affects the operation, management and maintenance of the water pump unit, but also affects the operation efficienc...
