摘要:
A quick change nozzle assembly for waterjet cutting has a nozzle body (20) separable from a nozzle cap (10), the nozzle body (20) providing a quick change assembly including a feed tube handle (40) making change possible without the use of tools, the separable nozzle body having included and aligned therein the required nozzle wear components such as a wear insert (35) and a focus tube (20).

摘要:
An abrasive waterjet cutting system is monitored and controlled by measuring at least one process parameter (P) and using that measurement as a comparison with a running average (P(ave)) of the process parameter as it may change over time. Optionally, the rate of change of the process parameter may also be used to signal an emergency condition, and extreme outer limits (L1,H1) of the process parameter may be used to define unacceptable operating conditions.

摘要:
A coupling and seal assembly couples a plunger (56), at one end thereof, to a ram (58) without bolting (with a resilient retaining ring (94)) and receives the other plunger end in a high-pressure cylinder (54) through centering and sealing components confined within the cylinder by keying means. No elements of the assembly are bolted together; the centering and sealing components are secured in the cylinder only by a single retaining ring.
