|
Serviceability |
Entire unit is designed
for ease of repair. All components are readily accessible. |
|
Standardization |
Many components are
interchangeable throughout the various lines. |
|
Full
Pressure Lubrication |
A frame-driven lube oil
pump provides pressurized, cooled oil through a full flow oil
filter to all moving parts in the frame. A divider block
distribution system supplies metered oil to cylinder bores and
rod packing. Stainless steel tubing is used throughout the
cylinder lubrication system. |
|
Unloading Devices |
Manual head-end variable
volume clearance pockets, pneumatic fixed volume clearance
pockets and pneumatic suction valve unloaders are available on a
limited optional basis. |
|
Heavy Duty Crankshaft |
Forged steel precision
machined with integral counterweights. |
|
Rugged Crankcase |
Heavily ribbed, (with
spacer bars for stiffening) high-strength cast iron base with
removable, lightweight aluminum top cover and removable end
covers for ease of access. |
|
Precision Bearing Shells |
Precision-machined,
tri-metal main and connecting rod bearings. |
|
Rugged Crossheads and Guides |
Cast iron crosshead
guides, external ribbing and removable side covers. One piece,
long life crossheads with direct full pressure lubrication at
top and bottom for minimum wear. Hardened and ground
steel crosshead pins. |
|
Rigid Connecting Rods |
Fabricated from forged
steel with four bolt, heavy duty "H" section. |
|
Quiet Auxiliary Drive |
Fully enclosed and
continuously lubricated chain drive adjusted by positive
positioning eccentric vernier. |
|
Oil
and Dust Seal |
Foolproof,
non-contacting crankshaft oil seal plus reliable non-wearing
dust seal. |
|
Proven Cylinder Design |
Non-cooled compressor
cylinders with ample nozzles and large gas passages.Cylinder
bodies are ion-nitride hardened and drilled for indicator ports. |
|
High
Strength Bolting |
Grade 8 bolts or B-7
studs on all pressurized components. All bolting designed for
accessibility. |
|
Efficient Valving |
Ariel uses plate-type
valves designed for modern speeds utilizing non-metallic sealing
elements as standard. Selected to adhere to established,
low valve velocity standards. |
|
Durable Pistons |
Wear-resistant ductile
or gray iron in all diameters. Available with rider rings (R
cylinders) and wear bands (RJ cylinders). |
|
Stout Piston Rods |
Short, stiff,
precision-ground alloy steel piston rods with locking crosshead
nut. All piston rods are ion-nitrided for surface hardness and
longevity. Rolled threads are 1/4" under rod diameter for easy
installation through packing. |
