Problems solved by technology

The conventional pre-cleaning method has the following disadvantages: 1) The purging is one-way purging, and the pipeline is complicated due to the direction of the pipeline, and there is a purge blind area at the joint of the pipe fittings, resulting in dirt accumulation that cannot be cleaned; 2) The compressed air pressure in the workshop is relatively low. Low, generally 0.6 ~ 0.8Mpa, the cleaning ability is weak, and some stubborn welding slag and other dirt cannot be cleaned

Embodiment Construction

[0022] like figure 1 As shown: the flushing system involved in the present invention includes the following devices: the air compressor 1 is used to provide high-pressure compressed air. Filter 2 is used to remove oil mist, water and other impurities in the compressed air to ensure dry and clean purge air. The one-way valve 3 prevents the compressed air from flowing back to the air compressor 1. The air tank 4 is used to store high-pressure compressed air. Pressure gauge 5 is used to show the compressed air pressure in the air tank. The valve 6 is used to control the opening and closing of the compressed air in the air tank 4 . Valve 7 and valve 11 are used to control the opening and closing of the purge pipeline. Flange 8 and flange 12 are used for connecting and disconnecting pipelines and temporary connecting pipes. The temporary connecting pipe 9 and the temporary connecting pipe 13 are used for temporarily connecting the purge pipeline and the main hydraulic pipeline...

Abstract

The invention relates to a hydraulic pipeline system and especially relates to a purge precleaning system of the hydraulic pipeline system. The bidirectional pulse purge precleaning system of the hydraulic pipeline system includes a gas storage tank with a pressure gauge; an air compressor is connected with the gas storage tank through a non-return valve; a pair of switch valves are connected in parallel in the outlet of the gas storage tank, and gas pipe interfaces are arranged in the outlets of the switch valves; the pipeline system includes a main pipeline P pipe and a main pipeline T pipe,gas pipe interfaces are arranged in the inlets of the main pipeline P pipe and the main pipeline T pipe, and the gas pipe interfaces are connected with the corresponding gas pipe interfaces in the outlets of the switch valves through temporary pipelines. The air compressor is used for inflating the gas storage tank to high pressure, and forward and reverse purge is realized by utilizing the connection and disconnection of the temporary connecting pipes. The precleaning with high efficiency and quality of the hydraulic pipelines is realized, and the flushing efficiency and quality of the subsequent oil flushing are improved.

Description

technical field [0001] The invention relates to a hydraulic pipeline system, in particular to a purging pre-cleaning system of the hydraulic pipeline system. Background technique [0002] The hydraulic system is an important part of metallurgical engineering. Thousands of meters of hydraulic and lubricating pipelines are like the "vessels" of the entire project, providing power for the unit, and the quality of hydraulic pipeline oil flushing directly affects the quality of the "vessels". unimpeded. The hydraulic system of large-scale metallurgical equipment has high control precision, and there are a large number of servo valves and proportional valves, which have high requirements for the flushing quality of hydraulic pipelines. In order to improve the efficiency and quality of oil flushing, pre-cleaning is generally carried out before hydraulic pipeline system oil flushing. [0003] The conventional pre-cleaning method is: use the existing compressed air pipeline in the ...
