Ariel KBB & KBV Gas Compressor

KBB Product Shot The KBB (900 RPM) and KBV (750 RPM) are Ariel's largest compressor frames. Both frames are rated up to 10,000 horsepower with 190,000 lbf combined tension and compression rod loads. They are especially well-suited for use in pipeline, storage, and high-pressure injection applications. A complete line of gathering and pipeline cylinders ensure maximum usage of the horsepower and rod load rating of these frames. The KBB and KBV frames are available in four- and six-throw configurations.

As with all Ariel compressors, regular, minimal maintenance insures a lifetime of continuous, trouble-free operation.

Features

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 Pneumatic fixed volume clearance pockets and pneumatic suction valve unloaders are available on most cylinders.
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 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 with 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 Forged steel, four bolt, heavy duty "H" section.
Quiet Auxiliary Drive Fully enclosed and continuously lubricated chain drive adjusted by positive positioning eccentric verniers.
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 or 17-4PH bolting on all pressurized components. All bolting designed for accessibility.
Efficient Valving 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 pistons, with wear bands.
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.

Cylinders

The long standing basis of Ariel's successful design philosophy is research showing that modern, moderate and high speed compressor cylinders do not require internal water cooling passages. The absence of water jackets results in larger gas passages, reducing pressure-drop losses and yielding the high efficiency Ariel cylinder for the same sized cylinder casting. The proven design of the Ariel cylinder eliminates the cost of the cylinder cooling system and the major maintenance problems associated with water cooling, such as scaling and corrosion.

Most Ariel cylinders are ion-nitrided, increasing surface hardness and reducing cylinder bore wear to an absolute minimum. Ariel cylinders, combined with the innovative design of every Ariel frame, have earned Ariel the reputation for the lowest operating and maintenance costs of any gas compressor available today.
