Abstract
Integeral tube pumping pump pump barrel internal surface manufacturing process is that pump barrel 1 internal surface of middle-carbon steel or medium carbon alloy steel carries out rough honing earlier, is coated with the coating of inhaling laser beam at pump barrel 1 internal surface successively then, and laser beam 11 is strafed pump barrel 1 internal surface, microhoning pump barrel 1 internal surface.
Description
The present invention relates to integeral tube pumping pump pump barrel internal surface manufacturing process.
At present, thermo-chemical treatment and mid frequency induction hardening tempering technology are all adopted in the processing of integeral tube pumping pump pump barrel abroad; Chromium plating on the pump barrel internal surface, nickel plating or ni-p electroless plating etc.; Because the heat treatment temperature height makes the pump barrel distortion big, pump barrel is difficult to fine finishing; Pump barrel plating inner surface or chemical plating, because coating is thin, the working life of pump barrel is short.
The objective of the invention is: provide a kind of pump barrel little in the heat treatment process distortion, the pump barrel internal surface adopts the laser beam method for processing, makes the integeral tube pumping pump pump barrel internal surface manufacturing process of pump barrel prolongation in working life.
The present invention is achieved in that pump barrel 1 internal surface of middle-carbon steel or medium carbon alloy steel carries out rough honing earlier, is coated with the coating of inhaling laser beam at pump barrel 1 internal surface successively then, and laser layer 11 is strafed pump barrel 1 internal surface, microhoning pump barrel 1 internal surface.
The process that laser beam 11 is strafed the pump barrel internal surface is, the focus lamp 8 that the laser beam 11 that laser 6 sends arrives on the scanner 10 by parallel beam expand device 7, be refracted on pump barrel 1 internal surface by the reflector on the scanner 10 9 then, scanner 10 1 ends are fixed, the rotating speed of pump barrel and scanning frequency be respectively 4.5-15 rev/min and 50-110 millimeter/minute.
Laser beam 11 power are 1.5-3 kilowatt, and laser beam 11 sweep rates are 36-54 mm/second clearance between focal point and surface 30-40 millimeter.
Middle-carbon steel or medium carbon alloy steel are No. 45 steel or 35CrMo and 25CrMo.
Advantage of the present invention is: the heat treatment process distortion of pump barrel is little, and the pump barrel internal surface adopts the laser beam method for processing, and pump barrel is prolonged working life.
Below in conjunction with accompanying drawing, the present invention will be further described with embodiment:
Fig. 1 is the integeral tube pumping pump structural representation.
Fig. 2 is laser beam processing pump barrel internal surface schematic representation.
In the accompanying drawing: 1, pump barrel, 2, plunger piston assembly, 3, the pump joint, 4, the pump valve assembly, 5, the pump valve one-way valve, 6, laser, 7, parallel beam expand device, 8, focus lamp, 9, reflector, 10, scanner, 11, laser beam.
Scanner 10 1 ends are fixed, and insert rough honing and be coated with and inhale in the pump barrel 1 of laser beam coating, the focus lamp 8 that laser 6 emitted laser bundles 11 arrive on the scanner 10 by parallel beam expand device 7, be refracted on pump barrel 1 internal surface through the reflector on the scanner 10 9 then, pump barrel was done straight line and was rotatablely moved this moment, make laser beam 11 strafe pump barrel 1 internal surface, finishing pump barrel 1 inner surface laser phase transformation quenches, pump barrel 1 internal surface forms a fine martensite helical ribbon surface through laser phase-change quenching, account for the long-pending 50-70% of entire pump tube inner surface, then microhoning pump barrel 1 internal surface.
