Abstract
Fluid cooled diaphragms for diaphragm compressors are provided which utilize a multi-layer diaphragm with an upper or gas contacting later, and a bottom or lower layer, which has cooling grooves through which cooling fluid is circulated to reduce the diaphragm temperature. Additionally the upper surface of the diaphragm may be subjected to high loading to indent the surface and produce grooves for gas escape passageways. The gas contacting and grooved layer can be joined over part of the entire surface, or the grooved layer not connected to the other layer. Two or more layers may be used as required.
Claims8
A fluid cooled diaphragm for diaphragm compressors which have a lower head and an upper head connected together with a gas inlet and outlet check valves for gas compression, a diaphragm between the upper and lower heads, fluid pressure means in the lower head to provide fluid pressure to the diaphragm the improvement which comprises,
- said diaphragm being of multi-layer construction, having at least an upper layer, and a lower layer,
- at least one of which layers is grooved for coolant flow,
- said at least one grooved layer having a plurality of grooves therein,
- said at least one grooved layer having inlet and outlet cooling ports therein,
- a source of coolant connected to said inlet port to provide coolant to circulate through said grooves and out said coolant outlet port.
