Reducing maintenance with liquid gaskets

Adopting a proactive upkeep technique is key to eliminating frequent failures modes and increasing the useful life of pumps, which is why liquid flange gaskets and thread locking adhesives can supply vital benefits over typical compression gaskets.
In today’s fast-moving, continually evolving industrial panorama, pump downtime could be extremely costly in misplaced output, particularly the place the pump has a production-critical function. For this reason, these operating in processing sectors similar to paper, power technology, chemical compounds, sugar, mining and oil and gas, will know all about the pressures that come with pump maintenance.
Conventional pre-cut compression gaskets are prone to long-standing issues like shrinkage, relaxation, extrusion and breakage, all of which might promote leaks between the bearing frame and adapter, or between the stuffing field and pump casing, for example. One way forward is to fully eradicate the requirement for a cut gasket by switching it with a liquid gasketing adhesive. Such a product fills all of the air area between the mating elements to create an ideal seal, whereas simultaneously eliminating flange face corrosion.
MRO workshops Among those able to benefit are maintenance, restore and operations (MRO) workshops, the place any liquid gasketing product must be fast and dependable, yet simple to dismantle for additional maintenance actions. In addition, the product should allow straightforward software and supply lower prices than traditional gaskets and slow-curing chemical options.
Loctite 518 a methacrylate-based gasketing product that’s sutiable the place low power is of paramount significance. According to the producers, this product can ship a 50% time saving thanks to quick cure instances, reducing the time required earlier than reaching the test bench. In addition, as a single-component adhesive, the product could be utilized utilizing both a gun or a brush, whereas providing low price and easy removal. The adhesive is suitable to be used on all kinds of pumps, together with centrifugal, submersible, diaphragm, disc and double- jacket.
A producer of cast iron gearboxes and geared motors reported that whereas the company was already utilizing liquid gasketing on an adapter assembly flange, the resulting poor seal was causing a 5% leakage price, along with testing and production delays as a result of adhesive’s slow cure rate.
After trialling different brands, the producer found that a Loctite gasket sealant met all of its performance standards. The product fills the gaps between the flange surfaces and cures shortly so that close-fitting components may be immediately strain examined to 276 kPa (40 psi). Leaks at the second are a thing of the past and disassembly is way simpler.
Shaft alignment Another widespread issue with pumps is shaft misalignment. When shafts on rotating equipment are misaligned, the potential for expensive, unplanned machine downtime rises dramatically. Typical among the many outcomes is untimely bearing failure.
A easy and cost-effective way to make sure and keep crucial shaft alignment is to fill the airspace with an acceptable liquid adhesive. This strategy has the effect of resisting vibration, shock, thermal growth and contraction by unifying the assemblies. Such an approach maintains the clamp load and keeps bolts from loosening, which in turn ensures ongoing shaft alignment. Ultimately, pump customers can lengthen mean time between failures (MTBF) and enjoy full bearing life expectancy.
Thread locking An industrial maintenance/engineering providers facility that had points with shaft alignment for an electrical motor and centrifugal pump that supplies water to the boiler of a industrial building. Previously, เกจวัดแรงดันถังแก๊ส loosening of mounting bolts was resulting in shaft misalignment and failures.
To overcome the problem, the upkeep specialist opted for a model new process. The company started cleansing the nuts and bolts using Loctite SF 7603, before aligning the shaft with a laser and applying Loctite 290 to the threads prior to fastening at the correct torque. This answer is proving profitable in maintaining alignment till the subsequent scheduled upkeep (every three years).
Proven adhesive and sealant merchandise are available to help with a myriad of additional pump upkeep duties. Retaining compounds, for instance, forestall bearings from fretting or spinning either on their shafts or within their housings. As one other example, quite a few products exist to help forestall corrosion or chemical attack.
