The three-beam four-column hydraulic press is contaminated during manufacturing, experimentation, use and storage. Keeping hydraulic oil, hydraulic components and piping clean is a must. So how to clean the hydraulic machine? Let's take a look.

 

1.Generally, when the three-beam four-column hydraulic press is used for cleaning, the hydraulic oil or the test oil of the working effect is often used. However, kerosene, gasoline, alcohol, steam or other liquids should not be used to avoid corrosion of hydraulic components, piping, fuel tanks and seals.

 

2.During the cleaning process, the hydraulic pump works together with the heating medium heating. When the temperature of the cleaning fluid is 50-80 ° C, the rubber slag in the hydraulic press is quickly removed.

 

3.During the cleaning process, the non-metallic hammer rod can be used to strike the oil pipe, which can be tapped in succession to eliminate the attachment in the pipeline.

 

4.intermittent operation of the hydraulic pump is conducive to further cleaning effect, the intermittent time is generally 10-30min.

 

5.A filter or strainer should be installed on the oil return path of the cleaning oil circuit. At the beginning of cleaning, due to the high amount of impurities, an 80 mesh screen can be used. In the later stage of cleaning, use a filter of 150 mesh or more.

 

6.Cleaning is generally determined by factors such as the degree of clutter of the system, the requirements of filtration accuracy, and the degree of contamination.

 

7.In order to avoid corrosion caused by external moisture, the hydraulic pump should continue to work until the temperature recovery stops normally.

 

8.After cleaning the three-beam four-column hydraulic press, clean the cleaning oil in the circuit.
