How Crankcase Lubrication is completed in Chicago Pneumatic Air Compressor.

Every Air Compressor has some rubbing parts which needs Lubrication.The most Metallic Parts are fitted in Running Gear which is also known as

CrankCase Parts.These parts are mostly Lubricated by Lubrication Oil through Oil Pump and Tubes.

A Oil Pump is used to Pump-Up and increase Oil Pressure which we filled in CrankCase Sump.

A Positive Displacement Rotary Pump directly driven by the CrankShaft through a Oil Pump Drive Shaft.Oil from the Frame Sump is drawn by the Oil Pump

through a fine perforated sheet strainer.

The Oil Pump discharge is taken to Cartridge Paper type Oil Filter and the Filtered Oil through the Copper pipes is led to each Main Bearings,Drive End and

Non-Drive End.

The Oil from Main Jouranals of the CrankShaft flows to Crank Pins through the rifle drilling holes and also from Crank Pins to Small End Pins through rifle

drilled hole in Connecting Rod.

Facing Beltwheel,having Clockwise direction of Rotation,the left hand Cross Slide which is fitted towards First Stage or Low Pressure Stage is Pressure

Lubricated.

A Copper Tube Connection is taken through a Tee Connection in Main Oil Line and connected to a Choke which is fitted on the top face side of the

Cross Slide.

The Lubrication Oil through the Choke flows to the centre of the Cross Slide to top of the Cross Head.

The Cross Slide and Cross Head fitted towards Second Stage or High Pressure Stage is Splash Lubricated in case of HX Models.Since the direction of

rotation is clockwise when viewed facing the Beltwheel,the splashed oil from the Second Stage Connecting Rod Bearing falls on the top of the Cross Slide.

The top of the Cross Slide is specially built with all around small dam in which the Splashed Oil accumulates and through the drilled hole,falls on top of

Cross Head for Lubrication.

In case of HN Model,which has higher capacity than HX Models,the Second Stage Cross Head is Lubricated through Choke.
