SSZL80II ZL80A lubricating oil filter: Double-cylinder paper filter core,lubricating oil enters the inlet of the filter through the transfer valve into the oil chamber, ,then enters the lubricating system of diesel engine,when the pressure difference of the inlet and the outlet surpass 0.2Mpa,the paper filter core is blocked and the safe valve opens, the oil is filtered through the safe filter and is discharged from the aleaning oil chamber. the normal pressure difference of the inlet and th eoutlet of the filter is 0.5-0.15Mpa.when it surpasses 0.17Mpa,the paper filter core must be exchanged and the safe filter cylinder should be washed.
