The Attwood Tsunami T500 Aerator Pump is among the best Livewell pumps, because of its appealing aesthetics and superior functionality. The aerator pump includes a large number of auxiliary features that guarantee the best Livewell performance. Unlike other similar Livewell pumps, this unit supports different voltages which range from 12V DC to13.6V DC. This helps it be appropriate for most forms of Livewell systems. Moreover, it comes with an output rating of 450 gallons each hour at nominal voltage and 500 gallons each hour at design voltage. Aside from its incomparable power, I loved the truth that this aerator pump includes a compact design that suits my small Livewell tank. Essentially, the pump supplies a dependable aeration performance even yet in confined spaces such as for example Livewell tanks and small boat bait systems. Another exciting facet of this pump is that it’s very easy to completely clean and keep maintaining. The pump includes a motor cartridge that locks and unlocks conveniently for secure placement and easy cleaning or replacement. With regards to durability, the Attwood 4640-7 Tsunami T500 Aerator Pump features top-class materials. The pump is constructed of high-quality bearings and premium rated brushes, magnets, and alloys made to withstand harsh, corrosive conditions and water damage and mold. Additionally, it includes a patented shaft seal that prevents the Livewell from leaking because of tinned wiring or misalignment.
A safety-critical system may necessitate a formal failure reporting and review process throughout development, whereas a non-critical system may depend on final test reports. The most frequent reliability program tasks are documented in reliability program standards, such as for example MIL-STD-785 and IEEE 1332. Failure reporting analysis and corrective action systems certainly are a common approach for product/process reliability monitoring. However, humans may also be excellent at detecting such failures, correcting for the coffee lover, and improvising when abnormal situations occur. Therefore, policies that completely eliminate human actions in design and production processes to boost reliability may possibly not be effective. Some tasks are better performed by humans plus some are better performed by machines. Furthermore, human errors in general management; the business of data and information; or the misuse or abuse of items, could also donate to unreliability. This is actually the core reason high degrees of reliability for complex systems can only just be performed by carrying out a robust systems engineering process with proper planning and execution in the validation and verification tasks.

This also contains careful organization of data and information sharing and developing a “reliability culture”, just as that using a “safety culture” is paramount within the development of safety critical systems. The focus on quantification and target setting (e.g. MTBF) might imply there’s a limit to achievable reliability, however, there is absolutely no inherent limit and development of higher reliability doesn’t need to become more costly. Furthermore, they argue that prediction of reliability from historic data can be quite misleading, with comparisons only valid for identical designs, products, manufacturing processes, and maintenance with identical operating loads and usage environments. Even minor changes in virtually any of these may have major effects on reliability. Furthermore, probably the most unreliable and important items (i.e. probably the most interesting candidates for your reliability investigation) are likely to become modified and re-engineered since historical data was gathered, making the typical (re-active or pro-active) statistical methods and processes found in e.g. medical or insurance industries less effective. Another surprising – but logical – argument is the fact in order to accurately predict reliability by testing, the precise mechanisms of failure should be known and for that reason – generally – could possibly be prevented!
Following the wrong route of attempting to quantify and solve a complex reliability engineering problem with regards to MTBF or probability using an-incorrect – for instance, the re-active – approach is described by Barnard as “Playing the Numbers Game” and is undoubtedly bad practice. For existing systems, it really is arguable that any attempt by way of a responsible program to improve the primary cause of discovered failures may render the original MTBF estimate invalid, as new assumptions (themselves at the mercy of high error levels) of the result of the correction should be made. Another practical issue may be the general unavailability of detailed failure data, with those available often featuring inconsistent filtering of failure (feedback) data, and ignoring statistical errors (which have become high for rare events like reliability related failures). Clear guidelines should be show count and compare failures linked to different kind of root-causes (e.g. manufacturing-, maintenance-, transport-, system-induced or inherent design failures). Comparing various kinds of causes can lead to incorrect estimations and incorrect business decisions concerning the focus of improvement.
