HH recommended system sampling frequency chart

We are often asked “at what frequency should I sample oil?” As a broad guide the table above can be used. If problems are suspected or if a machine is ‘mission critical’ then more frequent sampling is a sensible precaution! In all sampling situations it is vital that the machine is in operation or has…

A bit of background information on hydraulic flow

Flow of hydraulic fluids in pipes and hoses can be classified into one of three phases which are laminar, transition and turbulent flow. Laminar Flow Laminar flow, sometimes known as streamline flow, occurs when a fluid flows in parallel layers, with no disruption between the layers. At low velocities the fluid tends to flow without…
