High-pressure oil pipe inner wall cleaning device

Abstract

The invention discloses a high-pressure oil pipe inner wall cleaning device. The high-pressure oil pipe inner wall cleaning device comprises a power box and a cleaning plate, wherein the output end of the power box is connected with a cleaning rod through a coupler, three inverted-T-shaped grooves are formed in the outer wall of the cleaning rod, and inverted-T-shaped spiral seats are movably connected to the inner walls of the three grooves. A plurality of conical rubber protrusions are fixedly connected to the outer walls of one sides of the three inverted-T-shaped spiral seats, a plurality of springs are fixedly connected to the outer walls of one sides of the three inverted-T-shaped spiral seats, and the other ends of the springs are fixedly connected with the inner wall of one sides of the inverted-T-shaped grooves. According to the high-pressure oil pipe inner wall cleaning device, the mode that the high-pressure oil pipe inner wall cleaning device is rotated into a to-be-cleaned oil pipe is adopted, so that the situation that the inner wall of the oil pipe is damaged due to the fact that the oil pipe is small in caliber and collides with the inner wall of the oil pipe when forcibly plugged is avoided; meanwhile, pipeline correction can be conducted on the metal hose type high-pressure oil pipe in the plugging process through rotary plugging, so that subsequent inner wall cleaning operation is facilitated; and the inverted-T-shaped spiral seats are connected through the springs, so that contact between the cleaning device and the inner wall of a pipeline is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline cleaning, in particular to a cleaning device for the inner wall of a high-pressure oil pipeline. Background technique [0002] The high-pressure oil pipe is a part of the high-pressure oil circuit. The oil pipe is composed of a steel wire wound skeleton layer and an oil-resistant and corrosion-resistant synthetic rubber inside and outside. Transportation requires oil pipes to withstand a certain oil pressure and have a certain fatigue strength to ensure the sealing requirements of the pipeline. High-pressure oil pipes for vehicles mainly appear in high-pressure injection diesel engines and high-pressure injection direct-injection gasoline engines, and can withstand engine operation. required oil pressure.

Problems solved by technology

[0003] During the long-term use of the oil pipe, due to the internal oil transfer operation, the inner wall of the oil pipe will be scaled, which will affect the normal oil transfer efficiency of the oil pipe. Moreover, the current high-pressure oil pipes mostly use metal hoses, and the inner wall is wrinkled. Difficult to clean after fouling, such use will reduce its oil delivery, resulting in insufficient oil delivery and low power
