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

Water pump assembly axial clearance adjusting method
1. art
The present invention relates to the adjustment of water pump assembly axial clearance, especially the axial clearance of water pump and motor two coupling is adjusted, if two coupling axial clearances of water pump and motor do not meet the demands, by adjustment, make water pump parallel and concentric with motor two coupling, and the two axial lines of water pump and motor is located on the same line, to ensure the operation that unit is steady, safe.
2. background technique
Water pump assembly is widely used in field irrigation and draining, town water supply and draining, the water supply of industrial and mineral and enterprises and institutions and draining, for agricultural year stable yields plays decisive role; For the productive life of town dweller, industrial and mineral, enterprises and institutions provides reliable guarantee.The installation quality of water pump assembly not only directly has influence on the operation of water pump assembly, management, maintenance; Also have influence on operational efficiency and the working life of water pump assembly simultaneously.
If the axial clearance of water pump and motor two coupling does not meet the demands, and two shaft axiss are not on same straight line, and in operation, water pump spindle and motor reel are by Cyclic flexion stress influence, will make bearing heating, even cause unit vibration.By adjusting the axial clearance of water pump assembly, the installation quality of water pump assembly can be guaranteed, meeting the requirement that it runs, and improving its operational efficiency and working life.
3. summary of the invention
If water pump assembly axial clearance does not meet the demands, in operation, pump shaft and motor reel are by Cyclic flexion stress influence, will make bearing heating, even cause unit vibration.Therefore, water pump assembly must measure axial clearance after installing, and if do not met the demands, should adjust according to the gap width measured, and to ensure the installation quality of water pump assembly, makes it reach safety, run stably, and improves transmission efficiency.
Motor axis physical location (8) during installation is if depart from the axial location (6) when motor meets installation requirement, by not identical for the axial clearance caused between the coupling of water pump (3) and the coupling (4) of motor, namely there is the deviation of Δ b, according to the Δ b value recorded and geometrical relationship, before can calculating motor, after stone bolt position (9) and motor, stone bolt position (7) is answered shimming or is reduced the one-tenth-value thickness 1/10 of pad, the axial clearance of water pump assembly is met the demands, and make water pump axis and motor axis on same straight line.Refer to Figure of description.
The beneficial effect of patent of the present invention is, according to the measurement result of axial clearance can accurately, fast the front lower margin of calculating motor and rear lower margin place should adjust to obtain size, namely the front stone bolt position of motor and rear stone bolt position are answered shimming or are reduced the thickness of pad, make it to meet installation precision requirement, guarantee the installation quality of water pump assembly, and accelerate installation progress.
4. accompanying drawing explanation
Fig. 1 is horizontal pump unit axial clearance adjustment figure, further illustrates the utility model below in conjunction with accompanying drawing 1 and embodiment.1. water pump axis in FIG, 2. water pump spindle, the 3. coupling of water pump, the 4. coupling of motor, 5. motor reel, 6. axial location when motor meets installation requirement, 7. stone bolt position after motor, motor axis physical location when 8. installing, 9. stone bolt position before motor, D. water pump coupler diameter, Δ b.0 ° with the difference of 180 ° of position axial clearances, y 1. before motor, the thickness of shimming is answered at stone bolt place, y 2. after motor, the thickness of shimming is answered at stone bolt place.
5. embodiment
Rotate two coupling of water pump and motor in 0 °, 90 °, 180 °, 270 ° of positions, measure the axial clearance b value of 4 positions simultaneously.Axial clearance is b 1-b 3or b 2-b 4.(SL317-2004) " pumping plant is installed and acceptance specification " requires can not be greater than 0.05 ~ 0.08mm for rigid coupling axial clearance, and elastic coupling flexible coupling axial clearance can not be greater than 0.08 ~ 0.15mm.Otherwise need adjust the axial clearance of water pump assembly.
The motor forward and backward stone bolt place plus-minus thickness of pad or the movement value of left and right travel motor calculate by formula (1) and formula (2) according to similar triangle theory as shown in Figure 1.
y 1 = L 1 Δb D - - - ( 1 )
y 2 = ( L 1 + L 2 ) Δb D - - - ( 2 )
Y in formula 1---before motor, the thickness of shimming is answered at stone bolt place, mm;
Y 2---after motor, the thickness of shimming is answered at stone bolt place, mm;
L 1---before motor, stone bolt is to the distance of coupling end-face, mm;
L 2---the distance before and after motor between stone bolt, mm;
The external diameter of D---coupling, mm;
Δ b---locate the difference of axial clearance with 180 °, i.e. Δ b=b for 0 ° 1-b 3.
If b 1-b 3during for negative value, y 1and y 2should be negative value, the thickness of pad under namely representing motor base, should be reduced.
If b 1-b 3for on the occasion of time, y 1and y 2should be on the occasion of, namely represent the thickness that should increase pad under motor base.
Work as b 2-b 4or b 4-b 2when exceeding permitted value, motor moves by available jack or crowbar to the left or to the right, and controls the distance of movement with dial gauge.

Claims (1)

1. water pump assembly axial clearance adjusting method, the thickness y of the pad that should be added deduct by stone bolt before calculating motor 1should to add deduct the thickness y of pad with stone bolt place after calculating motor 2, it is characterized in that: by stone bolt before motor to the distance L of coupling end-face 1, the distance L before and after motor between stone bolt 2, the outer diameter D of coupling, locates the difference Δ b of axial clearance with 180 °, i.e. Δ b=b for 0 ° 1-b 3form.
