Problems solved by technology

At this stage, the commonly used pulling test device is only suitable for straight pipelines, so it is impossible to measure the force of the pig when it passes through the bend. The hydraulic drive pig bend test device has high requirements for experimental equipment and complicated process operations. And data monitoring is difficult, etc.

Abstract

The invention relates to a sprocket set driving tube cleaner curve pulling experimental device which comprises a tube cleaner driving system, an experimental pipe, a pipe support system and a tensionsensor measuring system. The pipe support system is used for supporting and fixing the experiment pipe. The tube cleaner driving system is formed by the cooperation of a driving sprocket set connectedto a motor and two driven sprocket sets and chains and is used for providing power for the operation of the tube cleaner. The tensile force measuring system comprises an S type tension sensor and a computer and is used for outputting operational resistance borne by the tube cleaner during an operation process in real time, and therefore, a driving force needed for the operation of the tube cleaner is predicted. Compared with the prior art, the device of the invention is applicable to a full-scale tube cleaner pulling experiment, the force condition of the tube cleaner in the operation processin a bent tube can be simulated in a realistic manner, the reliability of the data is ensured, the difficulty of the experiment operation can be effectively reduced, the cost of the experiment is controlled, and the force of the tube cleaner in the bent tube is the same as that in an actual tube cleaning operation.

Description

technical field [0001] The invention belongs to the field of pipeline cleaning, and in particular relates to an experimental device and an experimental method for pulling the curve of a sprocket group-driven pig. Background technique [0002] As a commonly used pipeline maintenance equipment, the safety and smoothness of the operation of the pig is the key to the success of the pigging operation. According to the experience of the engineering site, when the pig is running in the elbow, the rubber disc will be more severely squeezed and deformed, causing greater running resistance. Therefore, in order to avoid jamming accidents caused by insufficient driving force, it is necessary to build an indoor experimental platform to predict the minimum driving pressure required for pig operation in the early stage of pigging operation design. At this stage, the commonly used pulling experimental device is only suitable for straight pipelines, so it is impossible to measure the force ...
