Abstract
The present invention relates to Locomotive Engine Cylinder technical field, especially a kind of Locomotive Engine Cylinder seal groove restorative procedure, adopt welding and restoring process, comprise the following step: repair front inspection, polishing, elimination defect, micro-arc surfacing, micro-process, postwelding checks, processing, detect, pincers are repaiied, cleaning, protection.Adopt this restorative procedure, the repairing quality of cylinder jacket can be significantly improved, reduce engine operation troubles, use this restorative procedure that cylinder jacket can be avoided to scrap because seal groove bursts apart simultaneously, increase the service life, there is obvious economic benefit.
Description
Technical field
The present invention relates to Locomotive Engine Cylinder technical field, especially a kind of Locomotive Engine Cylinder seal groove restorative procedure.
Background technology
Locomotive Engine Cylinder, after utilization a period of time, finds the fault that its seal groove causes body to leak because bursting apart, and uses and brings potential safety hazard, scrap simultaneously, cause the wasting of resources, improve maintenance cost because of cylinder jacket seal groove disappearance to diesel engine.
Summary of the invention
In order to overcome existing above-mentioned deficiency, the invention provides a kind of Locomotive Engine Cylinder seal groove restorative procedure.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Locomotive Engine Cylinder seal groove restorative procedure, is characterized in that, selected restorative procedure adopts welding and restoring process, comprises the following step:
Step one, repair front inspection: penetrant inspection inspection, marks the defects such as each position crackle;
Step 2, polishing, elimination defect: before defect mending, using flame is heated to about 200 DEG C and removes surface of the work greasy dirt and oxide, to polish the injury region marked with the accurate sander of handhold mini-size, remove injury region peripheral fatigue layer, penetrant inspection checks, confirms that defect is eliminated completely;
Step 3, micro-arc surfacing: clean up injury region to be repaired with acetone, after the drying of acetone nature evaporation surface, after non-welding zone is protected, the welding of multilayer multiple tracks is carried out to fault location, rear one welding bead should cover 1/2 of front one weld seam, every soldering one deck, removes slag and has checked whether soldering defect, knock welding bead to eliminate repair welding stress with little top fuller, reduce weld defect and formed;
Step 4, micro-process: use the polishing of Miniature precision sander, Fiber Oil-stone, polishing repair welding position, the portion faces after sanding and polishing evenly and expose metallic luster, and should leave the machining allowance of 0.3mm, and repair welding border transition is level and smooth;
Step 5, postwelding inspection: penetrate inspection checks weld seam position flawless;
Step 6, processing: to confirming repair welding through inspection inspection, qualified cylinder jacket carries out machined by drawing to repair welding position in time;
Step 7, detection: carry out size detection by drawing;
Step 8, pincers are repaiied: thoroughly remove burr;
Step 9, cleaning: cylinder jacket is carried out cleaning and reached the requirement of cleannes 10 milligrams;
Step 10, protection: the qualified cylinder jacket of reparation is protected.
The invention has the beneficial effects as follows, adopt this restorative procedure, the repairing quality of cylinder jacket can be significantly improved, reduce engine operation troubles, use this restorative procedure that cylinder jacket can be avoided to scrap because seal groove bursts apart simultaneously, increase the service life, there is obvious economic benefit.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is schematic flow sheet of the present invention.
Detailed description of the invention
If Fig. 1 is schematic flow sheet of the present invention, a kind of Locomotive Engine Cylinder seal groove restorative procedure, is characterized in that, selected restorative procedure adopts welding and restoring process, comprises the following step:
Step one, repair front inspection: penetrant inspection inspection, marks the defects such as each position crackle;
Step 2, polishing, elimination defect: before defect mending, using flame is heated to about 200 DEG C and removes surface of the work greasy dirt and oxide, to polish the injury region marked with the accurate sander of handhold mini-size, remove injury region peripheral fatigue layer, penetrant inspection checks, confirms that defect is eliminated completely;
Step 3, micro-arc surfacing: clean up injury region to be repaired with acetone, after the drying of acetone nature evaporation surface, after non-welding zone is protected, the welding of multilayer multiple tracks is carried out to fault location, rear one welding bead should cover 1/2 of front one weld seam, every soldering one deck, removes slag and has checked whether soldering defect, knock welding bead to eliminate repair welding stress with little top fuller, reduce weld defect and formed;
Step 4, micro-process: use the polishing of Miniature precision sander, Fiber Oil-stone, polishing repair welding position, the portion faces after sanding and polishing evenly and expose metallic luster, and should leave the machining allowance of 0.3mm, and repair welding border transition is level and smooth;
Step 5, postwelding inspection: penetrate inspection checks weld seam position flawless;
Step 6, processing: to confirming repair welding through inspection inspection, qualified cylinder jacket carries out machined by drawing to repair welding position in time;
Step 7, detection: carry out size detection by drawing;
Step 8, pincers are repaiied: thoroughly remove burr;
Step 9, cleaning: cylinder jacket is carried out cleaning and reached the requirement of cleannes 10 milligrams;
Step 10, protection: the qualified cylinder jacket of reparation is protected.
More than illustrate just illustrative for the purpose of the present invention; and nonrestrictive, those of ordinary skill in the art understand, when not departing from the spirit and scope that claims limit; many amendments, change or equivalence can be made, but all will fall within the scope of protection of the present invention.
