Abstract

The invention relates to a tube cleaner speed controller with a hydraulic system. By means of the tube cleaner speed controller, the defects of a bypass valve control mode can be overcome. According to the technical scheme, front wheels are arranged on a base through supports and are arranged in the radial direction of the base, the lower ends of the supports are provided with compression springs, and the front wheels are connected with gear pumps; a radial plunger motor is arranged at the end of the base through a bolt, a speed changer is arranged at the center of the base, and an output shaft of the speed changer drives a mass block in a cylinder body to rotate; rear wheels are arranged on a rear end cover, the ends of connection rods A are fixedly provided with friction pieces, the friction pieces are closely attached to the outer edges of the rear wheels, the middle of each connection rod A is hinged to the rear end cover, the other end of each connection rod A is connected with the end of each connection rod B in a hinged mode, the other end of each connection rod B is hinged to a safety barrel, and the safety barrel is connected with a central shaft through a spline. The tube cleaner speed controller can be used just by being arranged on the rear side of a tube cleaner and can be suitable for various types of tube cleaning works.

Description

technical field [0001] The invention relates to a pig speed controller. Background technique [0002] In the process of pigging and testing oil and gas pipelines, general regulations require that the running speed of the pigging equipment is 3.5-5m / s; in order to obtain better quality of testing data, the running speed of the testing equipment in the pipeline is required to be lower than 5m / s ; Electromagnetic ultrasonic testing equipment requires its operating speed to be lower than 2m / s. The speed of the pigs changes greatly when passing through the uphill and downhill sections, curved sections, liquid accumulation, sand accumulation and fouling sections of the pipeline, and the direct use of conventional pigs cannot meet the speed control requirements. [0003] The speed control modes of existing oil and gas pipeline pigs are active control mode and passive control mode. [0004] The active control adopts the bypass valve control method, and its technical solution is: u...
