  • Patent number: 9695795
    Abstract: Various aspects of the technology provide for reducing noise and vibration in a pressure exchanger for high pressure fluid handling equipment such as a desalination system, by disposing grooves between a seal surface and a port. The groove reduces a hammer effect in moving high pressure fluid to a low pressure port and moving low pressure fluid to a high pressure port. Reduction in the hammer effect, in addition to reducing noise, reduces vibration that can cause deterioration of high pressure fluid handling equipment.
    Type: Grant
