Horizontal oil presses are contaminated during manufacture, testing, use and storage. While cleaning the elimination of pollution, so that hydraulic oil, hydraulic components and pipelines and other important means to keep clean.
In production, the cleaning of hydraulic press usually has the main system cleaning and the whole system cleaning. The whole system horizontal hydraulic press cleaning is to clean the whole hydraulic circuit of the hydraulic device. Before cleaning the system should be restored to the actual operating state. Cleaning medium available hydraulic oil; The cleaning time is generally 2-4h, or less than 10h under special circumstances; The cleaning effect is based on no impurities on the circuit filter.
Cleaning should pay attention to the following points;
(1) general horizontal hydraulic cleaning, more than the use of work with the hydraulic oil or test oil. However, kerosene, gasoline, alcohol, steam or other liquids should not be used to prevent corrosion of hydraulic components, piping, fuel tanks and seals.
(2) cleaning process, horizontal hydraulic pump operation and cleaning medium heating at the same time. Cleaning oil temperature is 50-80℃, hydraulic press in the rubber residue is easy to remove.
(3) in the cleaning process, the frame type hydraulic press can be used non-metallic hammer hammer oil pipe, can continue to knock, the frame type hydraulic press to remove the attachment in the pipeline.
(4) frame hydraulic pump clearance operation is conducive to improve the cleaning effect, intermittent time is generally 10-30min
(5) in the cleaning of the oil circuit return oil, should be installed with filters or filters. At the beginning of cleaning, due to more impurities, can use 80 mesh filter; Use more than 150 mesh filter in later cleaning.
6 cleaning time is generally 48-60h, which depends on the complexity of the system, filtration precision requirements and pollution level of hydraulic guide press factors.
7 guide hydraulic press in order to prevent external moisture caused by corrosion, cleaning the end, horizontal hydraulic press pump will continue to operate, until the temperature returns to normal.
We guide hydraulic cleaning machine after the circuit to clean oil elimination clean.
