Cleaning system for inner wall of seamless steel pipe

Abstract

The invention discloses a cleaning system for the inner wall of a seamless steel pipe. The cleaning system comprises a steel flatcar and a derusting steel pipe connected with the steel flatcar, a traveling motor and a rotating motor are respectively arranged on the steel flatcar, the derusting steel pipe is connected to an output end of the rotating motor, a rotating shaft is arranged in the derusting steel pipe, the front end of the rotating shaft extends out of the derusting steel pipe, a derusting steel wire brush is fixed to the front end of the rotating shaft, a steel pipe to be derusted and a steel support for supporting the steel pipe to be derusted correspond to the steel flatcar and the derusting steel pipe, a driving motor is arranged on the steel support and drives the steel pipe to be derusted to rotate through an output belt, and the derusting steel wire brush extends into the steel pipe to be derusted to grind, derust and clean the inner wall of the steel pipe to be derusted after the three motors are started. The inner wall of the seamless steel pipe can be rapidly and efficiently cleaned, the construction process is simple, operation is easily performed, construction period is shortened, and capital investment is saved.

Description

Technical field [0001] The invention relates to a seamless steel pipe inner wall cleaning system. Background technique [0002] Ammonia is one of the commonly used refrigerants. It is often used in large-scale refrigeration equipment. After the ammonia vapor flowing out of the evaporator enters the compressor, as the compressor continues to reciprocate compression, the internal pressure gradually rises, which finally forces the ammonia vapor to undergo a liquefaction reaction. This process is accompanied by a large amount of heat release. In order to ensure that the temperature of the liquid ammonia is not too high, the liquid ammonia immediately enters the condenser for cooling. The seamless steel pipe that transports the liquid ammonia bears important transportation tasks, so the inner wall of the steel pipe The surface treatment is very important. For the cleaning of the inner wall of seamless steel pipes, the current market common practice is: [0003] 1. Ordinary cleaning: [...

Problems solved by technology

[0010] Spraying (throwing) rust removal is driven by a high-power motor to rotate the spraying (throwing) blades at high speed, so that steel sand, steel shots, iron wire segments, minerals and other abrasives are sprayed (throwing) on ​​the surface of the steel pipe under the action of centrifugal force , not only can completely remove rust, oxides and dirt, but also the steel pipe can achieve the required uniform roughness under the violent impact and friction of abrasives, but the cost of rust removal by spraying (throwing) is relatively high, and the A large number of machinery and equipment and manpower and material resources, resulting in a waste of resources
