Abstract
The invention relates to a pump cover repair technology, particularly to a technology for repairing abraded portions of tilting shaft type hydraulic plunger pumps, and aims at providing the pump cover repair technology which is simple in technology, low in cost and saving in resources. The repair technology includes: step A, removing an original damaged cast iron slide in a pump cover; step B, welding a copper alloy at the position where the original cast iron slide is removed; and step C, processing the copper alloy welded on the pump cover into dimensions of the original cast iron slide.
Description
Technical field
The present invention relates to a kind of renovation technique, particularly relate to a kind of technique that wearing part in the hydraulic clino-axial piston pump is repaired.
Background technology
Hydraulic pump is the power set in the Hydraulic Power Transmission System, is energy conversion component, is driven by prime mover (motor or diesel engine etc.), and the pressure energy that the mechanical energy of inputting is converted to fluid outputs to and goes in the system, for executive component provides power.They are core parts of Hydraulic Power Transmission System, and whether its performance quality will directly have influence on system and work.Be processed with the cast iron slideway on the pump cover inner surface of hydraulic pump, the cast iron slideway is used for supporting the part (oil distribution casing of plunger displacement pump) in the pump cover, in the normal course of operation of hydraulic pump, the part that the cast iron slideway is in contact with it produces friction, friction can cause the wearing and tearing of cast iron slideway for a long time, and the wearing and tearing of cast iron slideway cause the hydraulic pump cisco unity malfunction.And the wearing and tearing of cast iron slideway can only be changed pump cover on the pump cover, change day expense of basis factory pump cover about 9000 yuan, the pump cover that Korea S produces is wanted about 3000 yuan, domestic pump cover is worth 2500 yuan, and the life-span of these accessory pump covers only is 3 ~ 6 months, both caused the increase of operation cost, the waste of the resource that also causes.
Summary of the invention
The technical problem to be solved in the present invention provides that a kind of technique is simple, cost is low, the pump cover renovation technique of saving resource.
Pump cover renovation technique of the present invention may further comprise the steps:
A, impaired former cast iron slideway in the pump cover is removed;
B, the position soldering copper alloy of removing at former cast iron slideway;
C, will be welded on the size that copper alloy on the pump cover is processed into former cast iron slideway.
Pump cover renovation technique of the present invention adopts the mode of machining that former cast iron slideway is removed in the wherein said steps A.
Pump cover renovation technique of the present invention, the mode of wherein said machining are Boring machine processing or Milling Process.
Pump cover renovation technique of the present invention will form the slideway welding groove after the former cast iron slideway removal in the wherein said steps A.
Pump cover renovation technique of the present invention adopts argon arc welding soldering copper alloy among the wherein said step B.
Pump cover renovation technique of the present invention, the processing mode to copper alloy among the wherein said step C is Milling Process and grinding.
Pump cover renovation technique of the present invention is that cast iron slideway impaired in the pump cover is removed, the position soldering copper alloy of removing, the copper alloy that will weld again is processed into the size of former cast iron slideway, again the wearability of the copper alloy slideway in the processing is better, pump cover after the reparation reaches more than 3 years general service life, has improved the service life more than 5 times than original pump cover.And the process of repairing is simple, and the technology that adopts all is existing mature technology, repairs required cost far below the cost of buying new pump cover.
Below in conjunction with accompanying drawing pump cover renovation technique of the present invention is described further.
Description of drawings
Fig. 1 is the top view that utilizes the pump cover after pump cover renovation technique of the present invention is repaired;
Fig. 2 is the stereogram that utilizes the pump cover after pump cover renovation technique of the present invention is repaired.
The specific embodiment
Pump cover renovation technique of the present invention may further comprise the steps:
A, impaired former cast iron slideway in the pump cover is removed, the method of removing former cast iron slideway can adopt the method for the machinings such as Boring machine processing or Milling Process, in order to reserve sufficient welding space to copper alloy and to reach firmly welding effect, then can when removing former cast iron slideway, process the slideway welding groove of the 1 millimeter degree of depth at pump cover.
B, adopt argon arc welding soldering copper alloy at the position that former cast iron slideway is removed.
C, recycling Milling Process and grinding technique will be welded on the size that copper alloy on the pump cover is processed into former cast iron slideway.
As depicted in figs. 1 and 2, be welded with four copper alloy slideways 2 on pump cover 1 inner surface after the reparation, copper alloy slideway 2 has replaced original impaired cast iron slideway on the pump cover 1, and the pump cover after the reparation reaches more than 3 years general service life, has improved the service life more than 5 times than original pump cover.And the process of repairing is simple, and the technology that adopts all is existing mature technology, repairs required cost far below the cost of buying new pump cover.
Above-described embodiment is described preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the prerequisite of spirit not breaking away from the present invention; various distortion and improvement that those of ordinary skills make technical scheme of the present invention all should fall in the definite protection domain of claims of the present invention.
