DIMENSION FILTER ELEMENTS AND DETERMINE THE DURATION

The gravimetric analysis is made to know the contents by weight of the solid particles which pollute the hydraulic oil. With this test it is possible to dimension in an accurate way, the filters to be installed on a plant. At the same time it is possible to determine, with a good approximation, the duration of the filter elements installed in a plant.

There are often situations where it is difficult to take a fluid sample from the plant, or there may be doubts about the exact point of withdrawal, or you may need to follow the various stages of the production process of the machine, in order to take in the most appropriate moment the sample of the fluid to analyze. In addition, during the plant start-up operations, it is necessary to know on site the conditions of the fluid, to permit corrections in real time.

For all these cases, the Controils portable system allows to give you the correct support, so that the required checks are made in an appropriate way.

Metallographic microscope for research applications. Camera Optikam PRO FULL HD.

The metallographic microscope, combined with precision camera, allows to observe nature, shape and size of the particles. Compared to the particle count, with this system you can have exact information about both what’s inside the fluid and at the same time, the quantity and the size. For example, you will be able to know whether the fluid is contaminated more with bronze or more with silica, or if there is material resulting from welding residues or if there may be problems with seals. Also it allows to rapidly solve situations which other analysis systems would require much more time.

There is always a certain amount of solid particles in suspension in the fluids. These particles can cause problems such as wear, erosion, bondings, seizures and other malfunctions in the plants. The particle counter counts the particles suspended in a specific volume of fluid passed through a capillary, grouping them by size. The various concentrations, in number and size in a given volume, determine the cleaning class of the fluid: the less the particles are, the lower the contamination class is, the cleaner the fluid is. Compare the values obtained with the particle count with those provided by the manufacturer of  the machine, lets you know if you are working properly or if there could be some problems.

Rotational viscometer Fungilab Master Expert Series with direct reading in CP, complete with adapter for low viscosity with impeller, housing and heating jacket supplied by a thermostatic bath complete with thermostat and electric heater

The oil, during its activity, tends to lose its additives and its properties. Among these, the viscosity is one of the most important one, since it is the force that binds together the molecules of the fluid and allows gear and bearings to continue to be lubricated and to function properly, even under high loads. It is very important to know if the oil has the viscosity expected: control it allows you to limit or prevent damage which otherwise could be fatal to the system.

Karl Fischer water analysis system

Water in oil is always present in more or less high concentrations, Limit to the minimum its presence helps to extend the life of the fluid and the components driven by the fluid

The water in a hydraulic oil is both in free form and dissolved: the free one is when it is found as microscopic droplets that may stack and create areas where lubrication is no longer performed with oil but with water; the dissolved is located when it is chemically linked to the oil molecules, in this case, the temperature variations of the fluid can break the ties making the water free again, returning to the previous situation. In addition to the lack of lubrication, the water contributes to "age" the oil due to the chemical reaction with the additives and reacts with the particles in suspension. In addition, in industrial transformers, the oil is used as a insulator: the water dissolved can create discharge problems. So it is important to know the content of water in oil, in order to limit it with corrective actions.
