Introduction

The NEA hybrid is the answer to the technically highly demanding emission- and oilfree compression. This novel innovation is also able to combine NEA's gas-tight crankcase with HOFER's diaphragm head. The multi-stage, one crank drive system offers a leakage-free solution for low suction and high discharge pressure ratio at higher mass flows.

Applications

Hybrid compressors are made from well-tried components: NEUMAN & ESSER reciprocating compressors and HOFER diaphragm compressors. Now a max. rod load of 1,700 kN is possible and a max. power of 30 MW producing up to 5,000 bar pressure. Applications are:

  • Chemical Industry
  • Plastic Production
  • Technical Gases
  • Fuel Cells

Benefits

  • Powerful piston stages for higher flows at lower pressure
  • Efficient diaphragm stages at high pressure
  • Cost-saving combination
  • Less number of stages
  • Less space regarding skid installation
  • Oil free gases with high purity
  • Gastight crankcase
  • Zero emission

Function and operational characteristics of diaphragm compressors

Gas is compressed in a double concave chamber by an oscillating sandwich diaphragm, which is hydraulically set into motion from one side. The diaphragm seals and separates the gas chamber hermetically against the drive unit. At the periphery, it is clamped between diaphragm cover and flange with perforated plate. It is set into oscillating motion by hydraulic pressure. The displacement of the plates causes the gas chamber between the diaphragm plate and the diaphragm cover to be enlarged respectively reduced with every cycle.

With the beginning of the enlarging of the gas space, the gas is sucked in from the suction tube via the suction valve. This is installed in the cover and with reducing the gas space, the gas is compressed through the discharge valve – also installed in the cover – into the discharge tube. The oil pressure, which is required for this bending movement of the diaphragm plates, is generated from the crankcase by the piston moving to and fro. The piston displacement nearly equals to the displacement inside the diaphragm head.

With the compression stroke the piston presses the hydraulic oil into the diaphragm head and there through the perforated plate to the rear side of the diaphragm head. Hereby the diaphragm is bent against the concave surface of the cover. In its return movement, the piston draws the diaphragm back against the also concave surface of the perforated plate.
