Millers-Xtra: Oil Sampling

Why should you take regular samples of your oil?

In many industrial applications, including injection moulding, the sump is often filled with oil then left to run throughout the year without an oil change. Bearings, gearboxes, actuators, valves and ejector pins can start to stick or wear, without the maintenance department knowing.

If the oil isn’t sampled regularly, it’s impossible to know whether everything is running smoothly, or if the machine is on the verge of a costly break down. Taking oil samples regularly for analysis keeps the maintenance department informed of the machine’s condition, and maintenance can be planned around production, saving both time and money.

What do the sample reports tell you?

Oil analysis reports include:

  • Viscosity: this is crucial for optimum lubrication, and can change due to contamination or oxidation.
  • Additive level: anti-wear, anti-corrosion etc. additive levels become depleted over time as they fulfil their purpose in the oil.
  • Contamination: oil can become contaminated by environmental factors such as water, dust and debris, as well as by other oils.
  • Wear metals: wear metals in the oil offer an insight into not just the health of the oil but the health of the machine components. High levels of a certain wear metal can indicate that a particular component may need replacing soon.

How does Millers-Xtra Oil sampling work?

An oil sample is taken using a sampling pump (right). A plastic sample bottle screws into the bottom of the pump, with a pipe in the top of the pump that leads directly through to the oil that requires sampling. This avoids any contamination of the oil sample.

Millers-Xtra sample kits include a plastic sample bottle and a pre-paid envelope.
