The Basics Of Variable Displacement Pump Controls

Sep 02, 2016 If I choose a 75 HP motor with a pressure compensated variable piston pump, the motor would stall before the pressure compensator could kick in and reduce the pump flow. Depending on the load, a load sense pump could also stall the 75 HP motor if the load pressure is high enough to use up the HP before the pressure compensator kicks in.

Edm 101: Electrical Discharge Machining Basics ...

Dec 15, 2017 The wire moves in a carefully controlled pattern, roughly analogous to a woodworker’s scroll saw, causing sparking to occur between the wire and the workpiece. Because the electrical discharge erodes by the wire and the workpiece, wire EDM machines use a spool of wire that’s continuously moving to present a fresh discharge path in the cut.

done on each material lot. Mechanical testing normally consists of both wire bond pull testing and shear testing. Because the weld areas for both the ball bond and the second bond are several times larger in cross section than the wire cross section, the pull test is not capable of testing the strength of either bond (the wire breaks first).

Using The Three

Notice that if we know the pitch (P) and the wire diameter (W), then for any particular pitch, the formula reduces to: E = M – Const where Const is a constant for a particular pitch and wire size combination. These are the constants given in the table above. Take a look at the first formula for a moment. The value 0.86603 is a constant
