Diaphragm Compressor Efficiency

Diaphragm Compressor Efficiency FAQ

Are diaphragm compressors any good?

High efficiency and low-power From an efficiency perspective, diaphragm compressors provide outstanding results. Due to horizontally opposed crankcase designs, PDC compressors, for example, can achieve up to 33% brake horsepower reduction in running power, as opposed to traditional in-line opposed designs with high suction pressures.

What is the efficiency of a diaphragm hydrogen compressor?

Since compression generates heat, the compressed gas is to be cooled between stages making the compression less adiabatic and more isothermal. The default assumption on diaphragm hydrogen compressors is an adiabatic efficiency of 70%.

What is the power of a 2 stage diaphragm compressor?

2-Stage Diaphragm Compressor PDC-13-900-3000-100% for Hydrogen Gas. The flow rate is up to 700 Nm3/Hr at 2.0MPa/290 psig suction and 20.0MPa/2,900 psig discharge pressure. Power consumption is 150 HP/132 kW. This reciprocating diaphragm compressor meets plant codes and standards.

How does the diaphragm move in an air compressor?

i, the diaphragm moves up, blocking the air vent line and forming a nozzle between the output pressure line and the supply air pressure line. More air goes to the output line and the air pressure increases. When p 2decreases, the diaphragm moves downwards, thus blocking the air supply line and connecting the output port to the vent.
