Station setting method for varnishing, drying and packing sucker rods

Abstract

The invention discloses a station setting method for varnishing, drying and packing sucker rods, which is mainly used for a one-by-one varnishing procedure, a continuous drying procedure and a bundling packing procedure of the sucker rods for an oilfield. The three procedures are developed to form fifteen stations including batch feeding, single-rod turnover i, single-rod conveying, single-rod turnover ii, shifting by the aid of a shifting wheel, continuous varnishing, single-rod pre-hanging, single-rod hanging, chain conveying, continuous drying, single-rod discharging placement, single-layer placement, transfer, drop bundling and outward whole-bundle lifting, and the fifteen stations are mutually connected to realize the three procedures, so that the sucker rod varnishing effect is ideal, drying speed is fast, and the sucker rods can be bundled and packed after being dried. The station setting method has the advantages of station setting reasonableness, short anticorrosion paint film forming cycle, safety and reliability in use of a flow production line, economical production environment, environmental protection, high production efficiency, high automation degree and the like, the varnishing quality of the sucker rods can be ensured particularly at low temperature in winter, and anticorrosion paint films are even and smooth.

Description

technical field [0001] The invention belongs to the technical field of sucker rods, in particular to a station setting method for soaking paint, drying and packing sucker rods used in oil fields. Background technique [0002] At present, the dipping process of sucker rods by various sucker rod manufacturers is either whole package dipping or manual painting. [0003] Whole package dipping is a process of putting the whole package of sucker rods together with the packaging frame directly into the anti-corrosion asphalt paint tank for dipping and forming a layer of anti-corrosion paint film on the surface of the sucker rods. The packaged sucker rod is lifted out together with the packing frame to drain the remaining paint and cure the anti-corrosion paint film. The part where the sucker rod and the packing frame are in contact with the whole package of dipping paint cannot be dipped into the asphalt paint, and the cycle of forming an anti-corrosion paint film on the surface o...
