Hydraulic pump not building pressure? Here’s what to check.
A sheared pump coupling is an obvious cause of failure, however the location of some pumps within hydraulic systems makes this difficult to check so it may go overlooked. 6. CHECK YOUR PUMP RELIEF VALVE. It is possible that the entire flow could be passing over the relief valve, preventing the pressure from developing.

Hard rock cutting with high pressure jets in various ambient pressure
Abstract. An alternative drilling technology has been developed, in which ultra-high pressure jetting with in excess of 2500 bar jet pressure is combined with mechanical drilling techniques. In order to investigate the cutting performance of the fluid jets in hard rock formations, experiments under various ambient conditions were performed.

Hydraulic flow and pressure specifications also need to be considered when pairing a breaker to a hydraulic system. If the carrier cannot provide enough flow at the right pressure, the breaker won’t perform with maximum output, which lowers productivity and can damage the breaker.

Tricone Bit
Referring to Table 2.2 for the hydraulic power optimization technique, the optimized pressure loss across the nozzles is 63%, hence (2.22) Δ P BIT = 0.63 × P MAX If the same example rig with a 6000 psi pumping system were being used, the optimum pressure drop across a tricone bit should be 63% of this or 3780 psi.

How much pressure in PSI was needed in the Ancient World to cut stones
If the stack was a thin-wall vertical tube in the sun, then heating the column of air would reduce it''s density, so the warmer air would be more buoyant and tend to rise. If the energy was extracted at the bottom of the stack, the pressure difference would be limited to less than the 14.5 psi of atmospheric pressure.
