General machines will have dirt after a long time in use,Hydraulic equipmentThe hydraulic components in the cleaning is not good for various reasons, which is a headache. Here are some cleaning methods for hydraulic components.
Solvent immersion cleaning immersion cleaning is to be cleaned parts immersed in the cleaning tank with heating equipment (heating temperature is generally 35-85 degrees Celsius), and in the cleaning liquid into the compressed air or steam, so that the cleaning liquid in the dynamic, immersion time 4-8 hours, for serious oil parts, cleaning also need to manually wipe.
2. Spray washing using pressure jet cleaning, suitable for large and medium-sized factory workshop continuous operation. The prepared heated aqueous solution is sprayed and cleaned at a pressure of 0.3mpa by the corrosion-resistant pump bar. Generally speaking, the cleaned parts go through three continuous spraying processes of the pre-washing chamber, the cleaning chamber and the hot water cleaning chamber. In addition, the air flow generated by compressed air can also be used to blow off pollutants, and the effect of pulsating air flow is better.
3. Mobile scrubbing can use a soft brush to remove dirt to maintain the precision and low roughness of the components. Such as mesh oil filter, always use a hard wire brush, sometimes damage the filter element or change the filter accuracy. Another example is the hydraulic valve body with high precision and low roughness. Nylon with abrasive ball is used to brush and grind the end of the valve hole, the junction of the orifice and the sink groove. The brush head of the nylon barbed brush is made of black nylon wire with a diameter of 0.3-0.6mm and green silicon carbide abrasive with a specification of m20
4. Ultrasonic cleaning uses ultrasonic waves of appropriate power to take into the cleaning fluid, and the stroke point-shaped tiny cavity suddenly collapses when the cavity mine is large enough to move, forming a partial vacuum. The surrounding fluid fills the vacuum at a very high speed, generating a strong boost and mechanical impact force on the order of thousands of atmospheres, thus peeling off the pollutants on the surface of the parts placed in the cleaning fluid. This method has a short cleaning time, good cleaning quality, and can clean parts that are complex in shape and cannot be cleaned manually. Compared with manual, the efficacy is improved by more than 10 times and the cost is reduced. However, the porous material of the oil filter has the effect of absorbing sound waves, which may affect the cleaning effect.
Heating volatilization method Some pollutants can be removed by heating to volatilize them, but this method cannot remove the carbon, ash and solid attachments remaining inside the hydraulic components.
