Abstract
A wearing resistant pump pipe comprises an anti-corrosion layer, a quenching layer and a wearing resistant layer. The wearing resistant pump pipe is characterized in that the wearing resistant layer is distributed in the quenching layer; and the anti-corrosion layer is arranged outside the quenching layer. The anti-corrosion layer is formed by anti-corrosion paint through coating. The wearing resistant layer is formed by wearing resistant welding rods through radial overlaying along the pipe wall by using the overlaying technology. The wearing resistant pump pipe is simple in structure and convenient to use.
Description
Technical field
The utility model relates to the building machinery field, specifically a kind of wear-resisting pump line.
Background technique
In building field, often can use concrete, carry these concrete, except a small amount of barreled etc., in heavy construction, often use pump truck, pump truck claims again concrete mixer, the machinery that utilizes pressure that concrete is carried continuously along pipeline.Formed by the pump housing and delivery pipe.Be divided into piston type, extruding type, hydraulic diaphragm formula by structural type.The pump housing is contained on the automobile chassis, remilitarizes scalable or tortuous boom, just forms pump truck.
Important component part on the pump truck is pump line, and the abbreviation in concrete delivery pump pipe road is because concrete is called for short concrete (t ó ng), so often be called the concrete pump line.Be readily appreciated that, pump line is a kind of novel construction engineering accessory product that occurs simultaneously along with the appearance of concrete pump, its appearance has improved the efficient of construction greatly, fast concrete conveyance is arrived the place that needs cast need to change into operating type artificial or one barrel of bucket of crane or a pipeful of bucket in the past, efficiency of construction has been improved nearly a hundred times.Pump line generally is divided into 125 and 150 two kind, and these two kinds respectively have high pressure and low pressure minute.The low pressure model of 125 type pump lines is that external diameter is the pipeline of Φ 133, and high pressure is that external diameter is the pipeline of Φ 140; The low pressure model of the pump line of 150 types is that external diameter is the pipeline of Φ 159, and high pressure is that external diameter is the pipeline of Φ 168.The tube head of pump line is the pipe joint through special processing, is connected with body by welding, and the connection of every pipeline then is to connect by the pipe clamp that precision casting technology processes.
Pump line is divided into again according to using scope and drags pump line and two kinds of the pump lines in ground, drags pump line to comprise jib pipe, hinge elbow, reducer and bend pipe, adopts cast steel casting to form.The ground pump line then is common 20# carbon steel, by fluid hose or straight-seam pipes, processes.
Because the thing of carrying is different, pump line is the easiest wearing and tearing.At present also there is not a kind of more effective and practical mode to reduce this wearing and tearing.
Summary of the invention
The utility model is above technical problem just, and a kind of wear-resisting pump line that has increased wearing layer is provided.
The utility model is achieved through the following technical solutions:
A kind of wear-resisting pump line comprises corrosion-resistant coating, quench hardened case, wearing layer, it is characterized in that quench hardened case inside is distributed with wearing layer, the quench hardened case outer installment corrosion-resistant coating.Corrosion-resistant coating adopts the anticorrosive coating spraying to form.Wearing layer be wear resistance electrode adopt bead-welding technology along tube wall radially built-up welding form.
Adopt pump line of the present utility model, because the wearing layer along the built-up welding of tube wall direction moves towards identical with tube wall, when delivering concrete, can not have influence on concrete conveyance, in addition, because the wearing layer of built-up welding adopts bead-welding technology, the surface can be uneven, during delivering concrete, the bump branch of wearing layer alleviates concrete to the wearing and tearing of pump line, thereby prolongs pump line working life.
Description of drawings
Accompanying drawing Fig. 1 is radially sectional structure schematic representation of the present utility model, and Fig. 2 is the horizontal sectional structure schematic representation of the utility model, wherein:
The 1-corrosion-resistant coating, 2-quench hardened case, 3-wearing layer.
Embodiment
Below in conjunction with specific embodiment the utility model is described further.
A kind of wear-resisting pump line comprises corrosion-resistant coating 1, quench hardened case 2, wearing layer 3, it is characterized in that quench hardened case 2 inside are distributed with wearing layer 3, quench hardened case 2 outer installment corrosion-resistant coating 1.Corrosion-resistant coating 1 adopts the anticorrosive coating spraying to form.Wearing layer 3 for wear resistance electrode adopt bead-welding technology along tube wall radially built-up welding form.
Adopt pump line of the present utility model, because the wearing layer 3 along the built-up welding of tube wall direction moves towards identical with tube wall, when delivering concrete, can not have influence on concrete conveyance, in addition, because the wearing layer 3 of built-up welding adopts bead-welding technology, the surface can be uneven, during delivering concrete, the bump branch of wearing layer 3 alleviates concrete to the wearing and tearing of pump line, thereby prolongs pump line working life.
Claims (3)
1. a wear-resisting pump line comprises corrosion-resistant coating, quench hardened case, wearing layer, it is characterized in that quench hardened case inside is distributed with wearing layer, the quench hardened case outer installment corrosion-resistant coating.
2. described a kind of wear-resisting pump line according to claim 1 is characterized in that described corrosion-resistant coating adopts the anticorrosive coating spraying to form.
3. described a kind of wear-resisting pump line according to claim 1, it is characterized in that described wearing layer be wear resistance electrode adopt bead-welding technology along tube wall radially built-up welding form.
