Oil Reservoir: Capacity 5-50 liters

Component Specifications

Definition

A sealed container designed to store, cool, and supply lubricating oil to the primary (roughing) pump in industrial vacuum systems. It maintains proper oil levels, facilitates heat dissipation, and ensures continuous lubrication to prevent mechanical wear and overheating during pump operation.

Working Principle

The oil reservoir operates by gravity feed or pressurized supply to deliver oil to the pump's moving parts. It includes baffles or separators to reduce oil foaming, a sight glass for level monitoring, and often incorporates cooling fins or coils to dissipate heat generated during pump operation, maintaining optimal oil viscosity and lubrication properties.

Materials

Carbon steel (ASTM A36), stainless steel (304/316), or aluminum alloy (6061-T6) with internal coatings for corrosion resistance. Seals made from nitrile rubber (NBR) or fluorocarbon (FKM).

Frequently Asked Questions

How often should oil be changed in a primary pump reservoir?

Typically every 3-6 months or after 2000 operating hours, depending on operating conditions and oil contamination levels.

Can different oil types be mixed in the reservoir?

No, mixing different oil types can cause chemical incompatibility, reduced lubrication efficiency, and potential pump damage.
