Cylinder packing element in common use and seal type

Cylinder structure of main parts are cylinder, cylinder head, piston, piston rod, sealing element, etc. , these parts are the most important parts in the cylinder, the cylinder under the new western style move to introduce the common types of sealing components and sealing. Commonly used packing element: cylinder cylinder common tangible seal, the sealing QY shaft and hole sealing ring, frameless shield, ZHM combination ring, with C shape hole sealing ring and CK shape axle hole dust ring, also have adopt Yx shaft with hole with sealing ring. Common seal material is nitrile rubber and polyurethane. Cylinder seal type: in common use. Piston seal piston has two places need to seal, one is the piston and cylinder dynamic seal; Another is the piston and piston rod connection place static seal ring is commonly used in. 。 Piston rod seal generally placed in the groove of cylinder head sealing and dustproof ring, to ensure that the reciprocating motion of the piston rod sealing and dustproof. 。 The sealing of cylinder head and cylinder connection generally adopts the O ring, installed in the cylinder head and cylinder with the groove. A static seal. Sometimes connected by rubber gasket installation in mouth, flat seal. By testing the piston compression stroke cylinder air leakage of different position change after the inlet valve closing, can estimate the vertical cylinder wear. If its not leak into the place such as the exhaust valve, cylinder pad, and air leakage detection of cylinder is still exceeds bid, indicates the badly worn to cooperate with the piston and cylinder clearance is too large, or piston ring counterpart, damage, lack of flexibility and lose sealing effect, lead to air leakage is too large.
