Abstract

The invention discloses a high-pressure pulsed turbulent flow pipeline flushing system. The high-pressure pulsed turbulent flow pipeline flushing system is characterized in that: the system comprises a main oil tank and an auxiliary oil tank, a heater is arranged in the main oil tank, and an oil pump motor assembly, a pressure sensor, a pilot-operated check valve and a flushed pipeline are sequentially connected between the main oil tank and the auxiliary oil tank; the other end of the oil pump motor assembly communicates with the main oil tank, electromagnetic valves for controlling the opening and closing of the pilot-operated check valve are arranged on both ends of the pilot-operated check valve, a temperature sensor is arranged on the main oil tank as well, and a filter pump assembly is connected between the main oil tank and the auxiliary oil tank as well. By adopting an energy accumulator, a constant-power variable pump and an instantly opening valve bank, the system can provide high-pressure, ultrahigh-flow flushing oil in a short time according to the requirements of pipeline varieties, consequently, violently turbulent oil is produced in the pipeline, and oil molecules irregularly and violently move up and down to clean the pipeline in a drilling manner.

Description

Technical field

[0001] The invention relates to a high-pressure pulse turbulent flow pipeline flushing system. Background technique

[0002] Hydraulic systems generally have hydraulic pipelines, especially large construction machinery, factories and other field equipment hydraulic pump stations, valve blocks, and actuators are all arranged in a distributed installation and connected by pipelines. However, it is very difficult to clean and control the inner wall of the pipeline. It is difficult for the site environment and construction methods to ensure that the inner wall is completely free from pollution. Moreover, this convenient and excessive attention seriously affects the construction efficiency. Therefore, the pipelines of the hydraulic system generally need to be flushed before online operation to eliminate foreign objects in the pipes.

[0003] At present, there are generally two types of pipeline flushing: 1. Self-circulation flushing, which is to short-circuit the end of...
