2016-12-2 · In a positive-displacement (PD) pump, a discrete amount of fluid is trapped, forced through the pump, and discharged. A gear pump is an example of a PD pump (Figure 2). This pumping principle produces a pulsating flow, rather than a smooth flow. Its output flow tends to vary little with respect to the pressure at the pump outlet, because the moving

Fundamentals of Vacuum | Hydraulics & Pneumatics

Depending on pump design, the vacuum limit ranges from 28 to 29.5 in.-Hg or about 93% or 98% of the maximum theoretical value. For some pump types, the maximum vacuum rating will be based on this practical upper limit. For others, where heat dissipation is a problem, the maximum vacuum rating might also take into account allowable temperature rise.

Vacuum Systems For Successful Robot Implementation .

The design of a vacuum system and choice of vacuum components for robot end effectors can be of crucial importance for a successful robot installation. This paper discusses vacuum solutions for robot end effectors, which increase the possibility of a successful robot installation. At the same time, I would like to resolve the misunderstanding that all vacuum ejectors are expensive to operate.
