Abstract

The invention relates to a series oil cylinder type acceleration controller, which is used for pipe pigging constructions such as detection, liquid drainage, and descaling in pipelines. Its technical scheme: the large oil cylinder and the small oil cylinder are arranged coaxially opposite each other, and are connected together through the cylinder block, the piston of the large oil cylinder and the piston of the small oil cylinder are close to each other, and the piston rods extend from the cylinder body respectively; the hydraulic pressure of the large oil cylinder and the small oil cylinder is The oil is connected to each other, and the large oil cylinder and the small oil cylinder are respectively provided with compression springs; the piston rod of the large oil cylinder is directly connected to the brake pad, or indirectly connected to the brake pad. The invention drives the brake pads to work by connecting the oil cylinders in series, and the force of the oil cylinders is amplified by the cooperation of large and small oil cylinders, so that a sufficiently large braking force can be obtained, and the anti-impact effect is good.

Description

technical field [0001] The invention relates to a series oil cylinder type acceleration controller, which is used for pigging construction such as detection, liquid drainage and descaling in pipelines. Background technique [0002] When the intelligent pig performs internal detection on the pipeline, the speed of the pig needs to be limited to a low range; otherwise, it is easy to cause problems such as inaccurate pipeline detection, impact between the pig and the elbow of the pipeline, etc. Conventional clean pigging operations also require the pig to run slowly, otherwise it is easy to cause problems such as reduced pigging efficiency and medium backflow. However, due to the compressibility of gas, the speed of pigs in natural gas pipelines is prone to large fluctuations. With the development of pipeline non-destructive testing technology, a pig speed closed-loop control technology has emerged, which mainly uses a servo motor to control the bypass valve in real time, and ...
