Technical details and manufacturing context for Reservoir Tank

Definition
The reservoir tank is a critical component of reservoir/pump assemblies that serves as a storage vessel for hydraulic fluid, coolant, lubricant, or other process fluids. It maintains fluid volume and pressure stability, provides surge capacity during pump operation, allows for fluid cooling and de-aeration, and facilitates maintenance access for fluid changes and system inspection.
Working Principle
The reservoir tank operates by providing a contained volume where fluid is stored at atmospheric or slightly pressurized conditions. Fluid enters from return lines and exits through suction lines to the pump. Baffles or internal structures may be incorporated to separate air from fluid, promote settling of contaminants, and maintain consistent fluid temperature through natural or forced convection.
Common Materials
Stainless Steel, Carbon Steel, Polyethylene
Technical Parameters

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Corrosion
Cause: Chemical attack from stored fluids or environmental exposure, leading to material degradation and potential leaks.
Structural fatigue cracking
Cause: Cyclic loading from thermal expansion/contraction, fluid level changes, or vibration, resulting in crack initiation and propagation.
Maintenance Indicators
  • Visible external corrosion, bulging, or weeping at seams/welds
  • Audible hissing or dripping sounds indicating leaks under pressure
Engineering Tips
  • Implement regular internal/external coating inspections and cathodic protection systems for corrosion control
  • Install strain gauges and conduct periodic non-destructive testing (ultrasonic thickness measurements) to monitor structural integrity

Compliance & Manufacturing Standards

Reference Standards
ISO 11439:2013 - Gas cylinders - High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles ASME Boiler and Pressure Vessel Code (BPVC) Section VIII - Rules for Construction of Pressure Vessels EN 13445 - Unfired pressure vessels
Manufacturing Precision
  • Wall thickness: +/-5% of nominal thickness
  • Overall dimensions: +/-2mm for lengths up to 2m
Quality Inspection
  • Hydrostatic pressure test (1.5x design pressure)
  • Ultrasonic thickness testing for corrosion assessment
