Small innovation of the cylinder piston

The gas cylinders we use are often incapable of inhaling because of the looseness of the cowhide bowl, which makes people feel inconvenient, even after the repair, it feels reciprocating. According to experience, I replaced the cowhide bowl with an O-ring (see picture), and then modified a piston to drill 6 holes of φ3mm at the bottom end of the piston. When the piston is lifted up, the O-ring seal moves with the piston bottom surface, and air enters from the gap between the upper part of the cylinder and the piston and 6 holes.

Rod Seals

1. Components of piston rod seal:

Polyurethane, polyformaldehyde, rubber

2. Purpose and function of piston rod seal:

The rod seal belongs to the dynamic seal. It is the seal that moves with the piston rod. It is one of the important components on the hydraulic support.

3. Use position of piston rod seal:

Guide sleeve, piston

4. Working principle of piston rod seal:

It is used at the contact part between the guide sleeve and the outer cylinder to seal the emulsion in the outer cylinder.

5. What effects will be caused by improper use or operation of piston rod seal:

1. Improper selection of cavity support material will wear the cavity and piston rod.

2. The size of the friction pair is inappropriate, causing wear.

3. Improper thread guide angle of cylinder barrel and piston end wear the sealing ring.

4. The seal ring is worn due to improper installation guide angle of the seal.

5. The surface of cavity and piston rod is rough, with scratches and worn seals.

6. The outer cylinder leaks and the jack does not maintain pressure.
