Product Specification

Gas Expansion Turbine

We are presenting a wide range of vertical, single acting and reciprocating type Gas Expansion Turbine that produces the cold air required for plant. Our gifted experts comprising of physicists, specialists and engineers, around others are well versed in their particular realms. We additionally have a spacious warehousing office that empowers us to entertain a mass request of a Gas Expansion Turbine.

Additional Information:

The expansion Turbine is vertical, single acting, reciprocating type. This produces the cold required for the plant. High pressure air enters through inlet valve at the start of downward stroke of the piston. On further downward motion, the inlet valve closes and entrapped Air expands. During upward stoke , outlet valve remains open and inlet valve remains closed.

 

Therefore, in downward stroke Air enters the cylinder and expands. In the upward stroke the expanded air is pushed outside. The electric Motor is used to start the machine. Thereafter the Engine is moved by the Air Pressure itself and during which time; the Engine motor retains the speed by acting as a brake. Since work is done by Air  in rotating the flywheel, it loses its heat content(enthalpy), thus the Air gets cooled. This cooling is more than that of an expansion valve.

An elementary factor for the function of an Expansion Engine is to use dry and carbon Dioxide free Air, as otherwise, ice and dry ice will form on valve seats, causing mal- function. The approx. temperature drop across Expansion Engine is 50 deg. C to 70 deg. C, depending on inlet air pressure, temperature and inlet cam position.

 

The Expansion Engine consists of three major units. -  

  • The drive unit.
  • The cylinder unit for air expansion.
  • The Hydraulic system for operating the valves.
The drive unit is similar to any reciprocating machine with usual parts. Such as, crank case, crankshaft, connecting rod, crosshead etc. The Expansion Engine has an extended crankshaft enabling the accommodation of the cam box. The moving parts are lubricated through a hole in crankshaft. Oil scrapper rings are provided to prevent oil escape to cylinder unit.

 

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