Bare Compressor pumps .

The Bare Compressor unit consists of cylinders and cylinder heads, fitted in V configuration on a crankcase. Valve flats are provided in between the cylinders and cylinder heads along with stainless steel finger type valve plates to perform air suction and discharge operations. Disc valves are provided for 15 HP models.

Advantage

  • Simple installation in a wide range of positions
  • Very limited checks and maintenance.
  • Extremely quiet operation due to high precision in machining and assembly.
  • Innovative assembly system for easy repairs.

Engineering features

Crank case
The crank case is made of high grade cast iron and houses the crankshaft assembly. It acts as the sump for the lubricating oil and is provide with an oil level indicator , a drain plug and a breather. The breather maintains a partial vacuum inside the crank case to facilitate proper
lubrication.

Crankshaft and connecting rod assembly.
The crankshaft and connecting rod assembly is precision machined and dynamically balanced. Single row heavy duty ball bearings are provided at both the ends of the crankshaft assembly. Connecting rod big end is provided with cylindrical steel roller and small end is provided with phosphor bronze bush bearing. The crankwebs are forged out of carbon steel, case hardened and precision ground. The crankshaft assembly is provided with an oil splasher for lubricating all moving parts by splashing the oil in the crank case.

Pistons
The pistons fitted to the connecting rod are of automotive type and are of low expansion aluminium alloy. The pistons are provided with plain, stepped compression and slotted oil control rings. The rings are made of special quality close grained pearlitic cast iron and designed for controlling wear and oil consumption to great extent. The gudgeon pins are of chromium steel, case - hardened and precision ground.

Cylinder and Cylinder head.
The cylinders and cylinder heads have deep fins for effective cooling and are made of high grade cast iron to ensure high wear resistance. The cylinder bores are precision honed. Air passages of the cylinder heads are generously curved for easy air flow.

Inlet air filter
Inlet air filter is fitted to suction port of LP cylinder head. This efficient dry type air filter is used to eliminate the dust particles in the suction air. This ensures maximum life for the cylinders and pistons.

Inter-cooler.
The inter-cooler is a deep finned aluminum pipe connecting the first stage discharge and the second stage suction and is provided with a safety valve set to open, if the pressure in the inter-cooler exceeds the limit mentioned in the technical data. The spindle of the safety valve can be lifter manually if required.

Flywheel-cum-fan pulley
Dynamically balanced flywheel-cum-fan pulley (driven pulley) mounted on the crankshaft and connected to the motor pulley (drive pulley) fitted on the motor shaft through V belts for driving the compressor. A fan is fitted to the driven pulley for cooling the compressor
