Service life cycle of filter press cylinders
Thread Content
What do you think is the expected service life of the main cylinder (300) in diaphragm filter presses? Is it normal for oil leakage to occur due to weld cracks after 2 years of use?
Our company purchased a diaphragm filter press manufactured in Province S in March 2015; after two years of use, cracks appeared in the welds of the cylinder cover, causing oil leakage. The warranty period for the main unit was one year. But personally, I don’t think this is a vulnerable component; what do you all think is the appropriate service life for hydraulic cylinders?
Our device is working well; we’ve been using it continuously, and the filter elements have been replaced
Cylinder cover? It should be the piston guide sleeve; it’s supposed to be forged and turned as a single piece, so there shouldn’t be any welds
It’s a quality issue; it’s sufficient to have sealing rings and similar items available according to the model, as this product hardly ever breaks.
Oil leakage due to weld cracks after 2 years is abnormal. Generally, internal and external leaks at the connection points do occur.
