Expansion Engine For Air Separation

Owing to our know-how of this area, we're affianced in exporting, manufacturing and supplying with a broad array of Expansion Engine for Air Separation for our prestigious customers in Mumbai, Maharashtra, India. Expansion Engines provided are supplied in distinctive end alternatives which include as vertical, unmarried acting, triple growth engine, reciprocating kind and perfectly suit up with the running requirements of business flowers. These are made to be had with three essential devices comprising cylinders unit, hydraulic structures and drive unit with the engines utilizing dry and carbon dioxide free air. It works by means of generating bloodless required for plant with high- stress air getting into via inlet valve at start of downward stroke of piston with inlet valve final on in addition downward motion main to growth of entrapped air.

Working Features:
Upward stroke allows outlet valve to remain open while inlet valve remains in closed position
In downward stroke air enters cylinder and expands with the upward stroke leading to expanded air being pushed outside
Support of electric motor to start the machine post which engine moves by air pressure itself its motor retains speed by acting as brake
As work is done by air in rotating flywheel, it loses its heat content (enthalpy) that makes the air cooled
Cooling achieved is more than that of expansion in an expansion valve
Making use of dry and carbon dioxide free air that allows approx. temperature drop across expansion engine to 50 to 70A C (depending on inlet air pressure, temperature and inlet cam position variables)

Corresponding Units of Expansion Engine:
The drive unit
The cylinder unit for Air expansion
The Hydraulic system for operating the valves

Drive unit -
Drive unit similar to any reciprocating machine with usual parts like crank case, crankshaft, connecting rod, cross head and others
Expansion Engine has extended crankshaft that allows accommodation of cam box
Moving parts are lubricated through hole in crankshaft
Oil scrapper rings provided to prevent oil escape to cylinder unit

Cylinder unit a
Cylinder unit handling process air consists of cylinder, piston, inlet and outlet Isolation Valve Assemblies
Ball valves actuated mechanically by Push Rod as per timing transmitted by cam
Push Rods are housed in stuffing box to avoid Air leakage and are actuated by the hydraulic system

Hydraulic system a
Work s as control system

Hydraulic oil is fed by a pump to a
Pressurized oil container for valve actuation
Lubricate crankshaft and drive and drive unit parts
Lubricate the rolled holders
