  2. Replacement of the filter element of the double barrel parallel pre-filtration device:


  (1) Close the oil inlet valve of the filter on the side of the filter element that needs to be replaced first, close the oil outlet valve after a few minutes, and then unscrew the end cover bolt and open the end cover;


  (2) Open the drain valve to completely drain the dirty oil to prevent the dirty oil from entering the clean oil cavity when replacing the filter element; c. Loosen the fastening nut on the upper end of the filter element, and the operator wear oil-proof gloves to hold the filter element and remove it vertically upwards Old filter element;


  (3) Replace the new filter element, pad the upper seal ring (the lower end has its own gasket), and tighten the nut;


  (4) Close the drain valve, cover the upper end cover (note that the seal ring is properly seated), and fasten the bolts.


  (5) First open the oil inlet valve, and then open the air outlet valve. When the oil is discharged from the air outlet valve, immediately close the air outlet valve, and then open the oil outlet valve; then operate the filter on the other side in the same way.


  The above is the introduction of the applicable range and replacement method of the lube oil filter. I hope everyone will understand the applicable range and replacement method of the lube oil filter, which will be helpful to everyone.
