Abstract
The utility model relates to a composite wear-resistant special pipe, which is characterized in that: the composite wear-resistant special pipe is composed of an inner container, an outer skin, supporting bars, resin fillers and a connecting flange, wherein the inner container is arranged in the outer skin, the inner container is supported in the outer skin through the supporting bars, a gap between the inner container and the outer skin is 5 mm, the resin fillers are arranged in the gap between the inner container and the outer skin, and the connecting flange is arranged at the connecting position of two composite wear-resistant special pipes; the inner container is made of wear-resistant high-chromium cast iron by casting with the hardness HRC of 56-62; the sheath is made of carbon steel ZG 270-500. The composite wear-resistant special pipe solves the problems that the special pipe is frequently replaced in production, the production efficiency is low and the like due to poor wear resistance of the special pipe in slurry conveying pipelines such as a dredge boat slurry pump, a mine slurry pump and the like, and the production efficiency of the slurry conveying pipelines is greatly improved.
Description
Technical Field
The utility model belongs to a special pipe for connecting a pipeline on slurry pump conveying equipment, and particularly relates to a composite wear-resistant special pipe.
Background
At present, in the prior art, a composite wear-resistant pipeline is traditionally adopted in a straight pipeline used for slurry conveying equipment such as a dredge boat slurry pump, a mine slurry pump and the like, the manufacturing method is manufactured by adopting a centrifugal casting method, but a slurry conveying pipeline is not completely composed of straight pipes and various special pipes, most of the existing special pipes are manufactured by carbon steel, and because the special pipes cannot be manufactured by centrifugation, the wear resistance is poor, and the special pipes are not comparable to the composite straight pipes. In the working process of the slurry pump, the abrasion resistance of the special pipe is low, so that the special pipe is frequently replaced, the production efficiency is greatly reduced, and manpower and material resources are wasted, so that the abrasion resistance of the special pipe becomes a technical bottleneck which troubles the slurry conveying pipeline engineering.
Disclosure of Invention
The composite wear-resistant special pipe overcomes the defects, and aims to solve the problems that the special pipe is required to be frequently replaced in production, the production efficiency is low and the like due to poor wear resistance of the special pipe in a slurry conveying pipeline of a dredge boat slurry pump, a mine slurry pump and the like.
The composite wear-resistant special pipe of the utility model is briefly described as follows:
the utility model discloses a composite wear-resistant special pipe, which is characterized in that: the composite wear-resistant special pipe is composed of an outer skin, an inner container, supporting bars, resin fillers and a connecting flange, wherein the inner container is arranged in the outer skin, the inner container is supported in the outer skin through the supporting bars, a gap between the inner container and the outer skin is 5 mm, the resin fillers are arranged in a gap between the outer skin and the inner container, and the connecting flange is arranged at the connecting position of two composite wear-resistant special pipes; the inner container is made of wear-resistant high-chromium cast iron by casting with the hardness HRC of 56-62; the sheath is made of carbon steel ZG 270-500.
The composite wear-resistant special pipe solves the problems that the special pipe is frequently replaced in production, the production efficiency is low and the like due to poor wear resistance of the special pipe in slurry conveying pipelines such as a dredge boat slurry pump, a mine slurry pump and the like, and the production efficiency of the slurry conveying pipelines is greatly improved.
