O-Ring Φ160×7, Mud Pump Crosshead GB3452.1-82 GB/T3452.1-1992 mud
pumps for drilling rigs
O-Ring Φ160×7, Mud Pump Crosshead GB3452.1-82 was used in Mud Pump
corsshead.
An O-ring, also known as a packing or a toric joint, is a
mechanical gasket in the shape of a torus; it is a loop of
elastomer with a round cross-section, designed to be seated in a
groove and compressed during assembly between two or more parts,
creating a seal at the interface.
O-rings are one of the most common seals used in machine design
because they are inexpensive, easy to make, reliable and have
simple mounting requirements. They have been tested to seal up to
5000 psi (35 megapascals) of pressure. The maximum recommended
pressure of an O-ring seal depends on the seal hardness and gland
clearance.
O-rings come in a variety of sizes. Society of Automotive Engineers
(SAE) Aerospace Standard 568 (AS568)[15] specifies the inside
diameters, cross-sections, tolerances, and size identification
codes (dash numbers) for O-rings used in sealing applications and
for straight thread tube fitting boss gaskets. British Standard
(BS) which are imperial sizes or metric sizes. Typical dimensions
of an O-ring are internal dimension (id), outer dimension (od) and
thickness / cross section (cs)
The O-ring may be used in static applications or in dynamic
applications where there is relative motion between the parts and
the O-ring. Dynamic examples include rotating pump shafts and
hydraulic cylinder pistons.
Static applications of O-rings may include fluid or gas sealing
applications in which: (1) the O-ring is compressed resulting in
zero clearance, (2) the O-ring material is vulcanized solid such
that it is impermeable to the fluid or gas, and (3) the O-ring
material is resistant to degradation by the fluid or gas.
Metric O-rings are usually defined by the internal dimension x the
cross section. Typical part number for a metric O-ring - ID x CS
[material & shore hardness] 2x1N70 = defines this O-ring as 2mm id
with 1mm cross section made from Nitrile rubber which is 70Sh. BS
O-rings are defined by a standard reference.
The World's Largest O-ring was produced in a successful Guinness
World Record attempt by Trelleborg Sealing Solutions Tewkesbury
partnered with a group of 20 students from Tewkesbury School. The
O-ring once finished and placed around the Medieval Tewkesbury
Abbey had a 364m circumference (approx 116m id) and a cross section
of 7.2mm.
