Problem solving

We offer a complete range of products and services for filtration, but above all the advice and technical assistance necessary to identify the most advantageous treatments for our customers, because they can improve the performance of the machines and, thanks to the programming of maintenance plans, hoc, help prevent breakdowns and arrests in production. La Ricambi Udinese offers hydraulic advice on filtration and similar, retrofitting sizing on filtration in pre-existing hydraulic systems.

PROBLEM SOLVING: WATER FILTRATION IN TEST BATHS

The problem

Water is used in industry in various form of application: both as process fluid, when it becomes part of the product, than for service applications. In case of service application, water has to be replaced frequently because if contaminated, loose its properties and it’s no more available for its use. In case of big quantities of polluted water, it’s easy to understand that handling costs could grow-up more and more, influencing negatively the final production costs.

The cause

In some heat exchanger production for example, water is used as test fluid to verify the perfect sealing of the system dipping it after being charged with compressed air, if bubbles start forming on the surface (bubble test) this means that the product is defected and must be re-worked or discarded. To work correctly, these test baths need clear water but very often, due to remaining oils, solid particles and other contaminants, water tends to become so polluted that changes its aspect in a milky/hazy way, making difficult to proceed with tests, obliging operators to expensive fluid changes.

The solution

Analysis made on water samples, have almost always given as a result the presence of solid contamination or contamination that could be handled with standard economic filtration systems; applying these filtration system as a “kidney filtration system” to the test baths, is possible to maintain longer than usual the water charge, lowering production costs for less stops of the production plant and a different test speed, moreover creating a lower impact on the ambient, due to a less exhaust fluid quantity to handle.
