Problems solved by technology

[0002] Lubricating oil, anti-rust oil, particulate matter and carbon deposits on the surface of hydraulic parts during processing cannot be removed by traditional cleaning techniques, especially those produced on the surface after explosive deburring. Carbon deposits are difficult to remove, and the total weight of residual particles is high, which cannot meet the surface cleanliness requirements of hydraulic parts

Embodiment 1

[0026] The process is carried out as follows:

[0027] a. Spray cleaning:

[0028] Put the workpiece in the rotary spray cleaning machine, and use pure water to clean the surface and inner surface of the workpiece in the same direction and opposite to each other at 360 degrees. o Omni-directional rotary spray cleaning, control the spray water pressure to 30MPa, and spray time to 5 minutes, to remove iron filings and burrs on the surface of parts;

[0029] b. Immersion cleaning:

[0030] Immerse the workpiece cleaned by spraying in step a in a water-based cleaning solution with a weight concentration of 3%, and soak for 5 minutes at a temperature of 50°C;

[0031] c. Powerful rotating turbulent cleaning:

[0032] Place the workpiece cleaned by immersion in step b in a rotary spray cleaning machine, rotate it vigorously and quickly spray a water-based cleaning solution with a weight concentration of 2% on the inner hole and inner cavity of the workpiece for 10 minutes, and co...

Embodiment 2

[0042] The process is carried out as follows:

[0043] a. Spray cleaning:

[0044] Put the workpiece in the rotary spray cleaning machine, and use pure water to clean the surface and inner surface of the workpiece in the same direction and opposite to each other at 360 degrees. o Omni-directional rotary spray cleaning, control the spray water pressure to 35MPa, and spray time to 3 minutes, to remove iron filings and burrs on the surface of parts;

[0045] b. Immersion cleaning:

[0046] Immerse the workpiece cleaned by spraying in step a in a water-based cleaning solution with a weight concentration of 2%, and soak for 3 minutes at a temperature of 75°C;

[0047] c. Powerful rotating turbulent cleaning:

[0048] Place the workpiece cleaned by immersion in step b in a rotary spray cleaning machine, rotate it vigorously and quickly spray a water-based cleaning solution with a weight concentration of 3% on the inner hole and inner cavity of the workpiece for 5 minutes, and con...

Abstract

The invention provides a cleaning process of hydraulic parts, which includes steps: a, spraying for cleaning, namely placing workpiece in a rotary spraying cleaner, and rotatably spraying purified water to clean the surfaces and the inner surfaces of the workpieces; b, immersing for cleaning, namely immersing the workpieces sprayed at the step a in aqueous cleaning liquid; c, powerful rotary turbulent cleaning, namely placing the workpieces immersed at the step b in the rotary spraying cleaner to quickly spray aqueous cleaning liquid to inner holes and inner cavities of the workpieces so as to achieve liquid surface oscillation for repeated cleaning; d, ultrasonic cleaning, namely placing the workpieces subjected to powerful rotary turbulent cleaning at the step c into an ultrasonic cleaner to clean the workpieces with the aqueous cleaning liquid; e, rinsing, namely using antirusting agent contained aqueous cleaning liquid to rinse the workpieces subjected to ultrasonic cleaning at the step d; f, hot air for drying, namely subjecting the workpieces rinsed at the step e to rotary hot air drying; and g, vacuum drying, namely subjecting the workpieces subjected to hot air drying at the step f to vacuum drying at the pressure of 8-10mbar for 3-5 minutes.

Description

technical field [0001] The invention relates to a hydraulic component cleaning process, which belongs to the field of machinery. Background technique [0002] Lubricating oil, anti-rust oil, particulate matter and carbon deposits on the surface of hydraulic parts during processing cannot be removed by traditional cleaning techniques, especially those produced on the surface after explosive deburring. Carbon deposits are difficult to remove, and the total weight of residual particles is high, which cannot meet the surface cleanliness requirements of hydraulic parts. In order to improve the cleaning effect of hydraulic parts, it is necessary to design a process that can meet the requirements of surface cleanliness of hydraulic parts. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a cleaning process for hydraulic parts with a total weight of residual particles ≤ 1 mg / kg, which meets the re...
