In hot-spraying techniques, the gait of march of walking dolly and the speed of rotation of pipe fitting are directly connected to the thickness and the quality of coating.In the spraying process, if pipe fitting rotates, dolly is motionless, and spraying can only be carried out on a certain circumferential surface of pipe fitting, and coating thickness can constantly thicken along with the prolongation of time, finally can cause coating shedding; If steel pipe does not change, walking dolly at the uniform velocity advances, and spraying just can only be carried out along some axial surfaces of steel pipe, can not the pipe fitting circumference be covered; So, have only when the speed of rotation of the gait of march of walking dolly and pipe fitting satisfies certain matching relationship, could be abound with at the up one-tenth circumference of outer surface of pipe fittings, the uniform hot spray coating of thickness.
The walking dolly gait of march is calculated by formula (1):
V = 2 π n 1 rf 1 P 60 f 2 - - - ( 1 )
V-walking dolly gait of march wherein; n 1-vehicle motor rotating speed; R-gear moderate radius of circle; f 1-dolly frequency converter frequency; The reduction ratio of P-dolly step-down gear; f 2-electric machine frequency 50Hz.This shows that carriage walking speed is controlled by the dolly frequency converter frequency.
The workpiece velocity of rotation is calculated by formula (2):
m = n 2 f 3 60 f 2 - - - ( 2 )
M-Workpiece Rotating speed wherein; n 2-clamping rotating mechanism motor speed; f 3-rotary frequency convertors frequency; f 2-electric machine frequency 50Hz.This shows that Workpiece Rotating speed is controlled by rotary frequency convertors.
Because the relation of walking dolly gait of march and pipe fitting rotating speed satisfies following formula:
V = m 60 × 2 tgα × L - - - ( 3 )
Wherein, The angle of α-nozzle spraying swath, the L-nozzle is to the workpiece surface distance.
Therefore, at first to confirm that nozzle is to the distance of workpiece and the angle of nozzle spraying swath according to the requirement (like thickness, fraction of coverage etc.) of pipe fitting coating; Draw the gait of march of walking dolly and the rotating speed of pipe fitting by formula (1) and formula (2) then.
