Adopting a proactive maintenance strategy is vital to eliminating widespread failures modes and extending the helpful life of pumps, which is why liquid flange gaskets and thread locking adhesives can supply important advantages over typical compression gaskets.
In today’s fast-moving, continually evolving industrial landscape, pump downtime can be extremely costly in misplaced output, significantly where the pump has a production-critical function. For this purpose, these operating in processing sectors corresponding to paper, energy era, chemicals, sugar, mining and oil and fuel, will know all about the pressures that come with pump maintenance.
Conventional pre-cut compression gaskets are prone to long-standing issues like shrinkage, rest, extrusion and breakage, all of which may promote leaks between the bearing body and adapter, or between the stuffing field and pump casing, for example. One way ahead is to completely eradicate the requirement for a cut gasket by switching it with a liquid gasketing adhesive. Such a product fills all the air space between the mating parts to create a perfect seal, while concurrently eliminating flange face corrosion.
MRO workshops Among these capable of benefit are upkeep, restore and operations (MRO) workshops, the place any liquid gasketing product must be fast and reliable, but simple to dismantle for additional upkeep activities. In addition, the product should permit simple software and supply decrease prices than conventional gaskets and slow-curing chemical options.
Loctite 518 a methacrylate-based gasketing product that is sutiable where low energy is of paramount significance. According to the producers, this product can deliver a 50% time saving due to fast cure times, reducing the time required earlier than reaching the take a look at bench. In addition, as a single-component adhesive, the product could be utilized using either a gun or a brush, whereas offering low price and simple removal. The adhesive is appropriate to be used on all kinds of pumps, including 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 meeting flange, the ensuing poor seal was inflicting a 5% leakage rate, together with testing and manufacturing delays as a end result of adhesive’s slow treatment rate.
After trialling different manufacturers, the manufacturer found that a Loctite gasket sealant met all of its performance criteria. The product fills the gaps between the flange surfaces and cures rapidly in order that close-fitting parts may be instantly stress tested to 276 kPa (40 psi). Leaks at the second are a factor of the previous and disassembly is much easier.
Shaft alignment Another frequent issue with pumps is shaft misalignment. When shafts on rotating tools are misaligned, the potential for pricey, unplanned machine downtime rises dramatically. Typical among the many outcomes is untimely bearing failure.
A simple and cost-effective way to ensure and maintain important shaft alignment is to fill the airspace with an appropriate liquid adhesive. This strategy has the effect of resisting vibration, shock, thermal enlargement and contraction by unifying the assemblies. Such an method maintains the clamp load and keeps bolts from loosening, which in turn ensures ongoing shaft alignment. Ultimately, pump customers can lengthen imply time between failures (MTBF) and luxuriate in 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 business constructing. Previously, the loosening of mounting bolts was leading to shaft misalignment and failures.
To overcome the problem, the upkeep specialist opted for a new process. The firm 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 previous to fastening at the proper torque. เกจวัดแรงดันถังออกซิเจน is proving successful in sustaining alignment till the next scheduled maintenance (every three years).
Proven adhesive and sealant products are available to help with a myriad of further pump upkeep tasks. Retaining compounds, for example, prevent bearings from fretting or spinning either on their shafts or within their housings. As one other example, quite a few merchandise exist to help forestall corrosion or chemical assault.
