Description

The flat seizing mechanism for oil-gas separating filter element of variable-diameter

Technical field

The present invention relates to a kind of flat seizing mechanism, in particular for making the flat seizing mechanism of oil-gas separating filter element.

Background technology

The function of oil-gas separating filter element be be used in the compression process to lubricate, the oil of function such as cooling, sealing separates with pressurized air.Oil after the separation is got back to head and is recycled, and the pressurized air that contains certain oil mass is used for the back level as propulsion source, and the gas oleaginousness after the separation is few more, and the filter core differential pressure is low more good more.

The oil-gas separating filter element branch has two kinds of forms at present: a kind of is the flat formula that twines, and the glass fiber filter paper that is about to submicron order is wound on the barrel-contoured filter core supporting network excircle, and multilayer-wound carries out the first time and separates as required, carries out the second time through polymer layer again and separates; Another kind is collapsible, is about to the glass fiber filter paper kalamein mesh grid of multilayer submicron order, is processed into accordion and is placed on and carries out first time on the supporting network and separate, and carries out the separation second time through polymer layer again.

The filter paper winding quality problem of oil-gas separating filter element is the common problem that the oil content core is produced, and filter paper is reeled should be even, so the filter core quality that the filter paper coiling adopts mechanical flat seizing mechanism to produce is more stable.Existing paper wrapping machine such as Fig. 1 comprise frame 2, belt pulley (comprising belt) 3, motor 4, guide-bar mechanism 5, thimble link span 6, S.
