SUCTION STABILIZER FOR PUMP ASSEMBLY |
摘要 |
A fluid flow stabilizing method and a pump having a stabilized fluid flow passage where a process fluid contains suspended solid particles and is subject to pressure oscillations. The method comprises positioning an expandable membrane along the lower transverse surface, inflating the membrane with a compressible fluid, and alternatingly expanding and contracting the membrane to dampen the pressure oscillations and inhibit settling of the solid particles at the lower transverse surface. The pump comprises a stabilizer comprising a compressible fluid in an expandable membrane elongated along the lower transverse surface of a manifold in fluid communication with the fluid end. Another method comprises reciprocating a plunger in the pump to pass a slurry through the manifold, and alternatingly expanding and contracting a stabilizer in the manifold. |

1. A stabilized pump manifold, comprising:
a manifold in fluid communication with a fluid end of a pump for passage of a process fluid therethrough over a lower surface transverse to vertical, wherein the lower surface is elongated in a direction of fluid flow through the manifold; and a stabilizer comprising an expandable membrane elongated along the lower transverse surface and defining a compliant chamber comprising a compressible fluid in the direction of fluid flow to dampen pressure oscillations within the manifold; wherein the expandable membrane is capable of expansion and contraction pulsations; and wherein the compliant chamber spans the length of the expandable membrane. |
