Reducing maintenance with liquid gaskets

Adopting a proactive maintenance strategy is key to eliminating widespread failures modes and increasing the useful life of pumps, which is why liquid flange gaskets and thread locking adhesives can provide vital benefits over conventional compression gaskets.
In today’s fast-moving, continuously evolving industrial landscape, pump downtime may be extraordinarily pricey in lost output, significantly the place the pump has a production-critical function. For this cause, those operating in processing sectors such as paper, energy technology, chemicals, sugar, mining and oil and gas, will know all about the pressures that come with pump maintenance.
Conventional pre-cut compression gaskets are susceptible to long-standing issues like shrinkage, leisure, extrusion and breakage, all of which can promote leaks between the bearing body and adapter, or between the stuffing field and pump casing, for instance. One way ahead is to completely eradicate the requirement for a reduce gasket by switching it with a liquid gasketing adhesive. Such a product fills all the air space between the mating parts to create an ideal seal, while simultaneously eliminating flange face corrosion.
MRO workshops Among those in a place to profit are maintenance, repair and operations (MRO) workshops, where any liquid gasketing product must be quick and reliable, but straightforward to dismantle for additional upkeep activities. In addition, the product should allow simple utility and provide lower prices than traditional gaskets and slow-curing chemical solutions.
Loctite 518 a methacrylate-based gasketing product that’s sutiable where low power is of paramount importance. According to the producers, this product can ship a 50% time saving because of fast cure times, lowering the time required earlier than reaching the check bench. In addition, as a single-component adhesive, the product can be utilized utilizing either a gun or a brush, while providing low cost and easy removing. 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 using liquid gasketing on an adapter assembly flange, the resulting poor seal was causing a 5% leakage rate, together with testing and manufacturing delays because of the adhesive’s gradual treatment rate.
After trialling alternative manufacturers, the producer discovered that a Loctite gasket sealant met all of its performance standards. The product fills the gaps between the flange surfaces and cures quickly in order that close-fitting components may be instantly pressure examined to 276 kPa (40 psi). Leaks at the second are a thing of the previous and disassembly is much easier.
Shaft alignment Another frequent concern 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 premature bearing failure.
A simple and cost-effective way to ensure and maintain important shaft alignment is to fill the airspace with a suitable liquid adhesive. This strategy has the effect of resisting vibration, shock, thermal expansion and contraction by unifying the assemblies. Such an approach maintains the clamp load and keeps bolts from loosening, which in flip ensures ongoing shaft alignment. Ultimately, pump customers can prolong imply time between failures (MTBF) and enjoy full bearing life expectancy.
Thread locking An industrial maintenance/engineering services facility that had issues with shaft alignment for an electric motor and centrifugal pump that supplies water to the boiler of a industrial constructing. Previously, the loosening of mounting bolts was resulting in shaft misalignment and failures.
To overcome the difficulty, the maintenance specialist opted for a new course of. nuova fima pressure gauge ราคา began cleaning the nuts and bolts utilizing Loctite SF 7603, earlier than aligning the shaft with a laser and applying Loctite 290 to the threads prior to fastening at the proper torque. This resolution is proving successful in sustaining alignment until the subsequent scheduled upkeep (every three years).
Proven adhesive and sealant products are available to assist with a myriad of additional pump upkeep tasks. Retaining compounds, for example, forestall bearings from fretting or spinning either on their shafts or within their housings. As another instance, quite a few products exist to help prevent corrosion or chemical assault.
