What is the function of the polytetrafluoroethylene flow blocking ring in the high-pressure reciprocating pump? What aspects should be paid attention to during processing?
It functions as a seal, just process it as required.
The function of the choke ring is to prevent cold flow in the packing ring. To put it bluntly, it prevents the packing from deforming. It must be processed according to the requirements to ensure dimensional accuracy.
To protect the packing, that is, to protect the tangential ring and radial ring
