定义
The pump block or housing is a precision-engineered structural component that serves as the main body of a high-pressure pump unit. It provides mounting surfaces, alignment features, and sealed chambers for pistons, valves, and bearings while withstanding extreme internal pressures and mechanical stresses. This component ensures proper fluid flow paths, maintains component alignment, and prevents leakage in demanding industrial applications.
工作原理
The pump housing creates sealed pressure chambers where reciprocating or rotating pump elements generate hydraulic pressure. It directs fluid flow through precisely machined passages while providing structural integrity to contain high internal pressures (typically 100-700 bar). The housing maintains geometric stability under thermal expansion and mechanical loading to ensure consistent pump performance.
材料
High-strength cast iron (GGG-40/50)ductile iron (EN-GJS-400-18/500-7)or forged steel (42CrMo4) with hardness 180-250 HB. Pressure-containing surfaces often have hardened coatings or liners for wear resistance.

5-50 kg depending on pump size
Surface Finish
Ra 0.8-1.6 μm for sealing surfaces

常见问题

What are the critical quality checks for pump housings?

Pressure testing (1.5x rated pressure), dimensional verification of bore alignments, surface finish measurement of sealing areas, and material certification for pressure vessel applications.

How does housing design affect pump efficiency?

Optimized internal flow paths reduce turbulence and pressure drops, while precise bore alignments minimize internal leakage and mechanical losses, improving overall pump efficiency by 3-8%.
