I don’t emphasize contamination control much these days. Primarily because I believe the message has saturated its audience—those willing to heed it have likely already done so. That’s a positive outcome. 

Additionally, contamination control alone isn’t a panacea for Car Lift Repair Tampa Florida hydraulic equipment reliability anymore. Nowadays, it’s more of a foundational requirement for reliability. Given the advancements in technology for excluding and eliminating contaminants, failure to control contamination could be seen more as a flaw in machine design rather than a maintenance oversight.

However, effective contamination control shouldn’t be overlooked. It’s always beneficial to be reminded of the reliability advantages of enhancing Car Lift Repair Tampa Florida oil cleanliness. For instance, consider the experience shared by Car Lift Repair Tampa Florida.

Simultaneously, we advised the customer to enhance their filtration system, as we believed the original setup was insufficient—indicated by ISO 4406 figures of around 22/20. They agreed to upgrade the filtration as per our recommendations.

Before the filtration upgrade, they experienced frequent pump failures, averaging three variable piston pump replacements per machine per season. After witnessing positive results with the prototype’s new filtration system, they upgraded two more machines in the first season. This resulted in ISO cleanliness codes of 18/15 for these three machines.

Armed with this data, the end user persuaded the harvester manufacturer to adopt the same transmission and filtration system across the assembly line. By the fourth year, approximately 15 machines at the same sugar cane mill were equipped with the new transmission and filtration system, and they were only changing one variable piston pump per machine every three seasons—a ninefold increase in pump life!”

While this anecdote isn’t a formal scientific study on the benefits of improving oil cleanliness—it’s clear that additional modifications were made to the hydraulic circuit alongside the filtration upgrade—the remarkable increase in Car Lift Repair Tampa Florida pump life cannot be disputed.

This situation epitomizes the adage of being excessively thrifty in minor expenses while incurring significant losses. It showcases the consequences of allowing bean counters or non-technical managers to lead operations. Under such leadership, a critical aspect is often overlooked: the rationale behind oil changes.

Typically, water or particle contamination doesn’t mandate an immediate Car Lift Repair Tampa Florida oil change as these contaminants can be effectively filtered out. However, relying solely on offline filtration doesn’t address all potential oil-related issues.

Similar to a doctor diagnosing a patient before prescribing treatment, a thorough assessment is necessary before deciding on the appropriate oil management strategy. Simply hooking up a filter cart at regular intervals, devoid of any signs of oil degradation, is excessive servicing. It’s akin to taking antibiotics when not medically required—no harm done, but a needless expenditure.

In this context, despite the member’s good intentions, they’re prioritizing action over understanding the problem first. The logical initial step should involve advocating for an oil analysis program with management. A well-executed program provides comprehensive insights to manage oil cost-effectively.

Through oil analysis, one can ascertain when to employ the filter cart and the specific contaminants to target—be it solid particles, varnish, sludge, or water. Equally crucial, it signals when further filtration is futile due to oil oxidation or additive depletion. Just as there’s no point in persisting with futile efforts, filtering exhausted oil is futile; it’s time to start afresh.

When utilizing a portable filter cart, it should be connected to the Car Lift Repair Tampa Florida hydraulic reservoir to maximize the separation between its inlet and return. Ideally, the oil should be at operating temperature during filtration to ensure optimal exchange between the tank and the system.

Filtration duration varies depending on factors like contaminant type and concentration, system volume, and filter cart capacity. While oil analysis determines the endpoint, a general guideline suggests passing the total oil volume through the filter cart around eleven times.

For instance, consider a system with a 100-gallon reservoir and an estimated 40 gallons in the rest of the system. If the filter cart operates at 0.5 gallons per minute, the filtration duration can be calculated:

11 x 140 = 1540 gallons

1540/0.5 = 3080 minutes or 51.3 hours

While this example may warrant a larger filter cart, in industrial settings, such filtration duration might be acceptable. However, it’s essential to remember that this is a rough guideline; success is ultimately determined by oil analysis validation.

While conducting fact-checking for a consulting project recently, I revisited Australian Standard AS 2671-2002, which outlines the General Requirements for Systems in Hydraulic Fluid Power. Essentially mirroring the International Standard ISO 4413, the Australian version incorporates some adjustments based on input from the local advisory committee.

One notable amendment concerns suction strainers. According to Section 8.3.3 of ISO 4413:2010, filtration on pump suction lines should not be employed unless explicitly agreed upon by both the purchaser and supplier. Instead, inlet screens or suction strainers are deemed acceptable.

However, AS 2671 diverges from this provision by stipulating that unless mutually consented to by both the purchaser and supplier, filtration, inlet screens, or strainers on pump suction lines should not be utilized.

In essence, while ISO 4413 allows machine builders to install suction strainers without consultation or agreement from the machine owner, this is not the case in Australia. Compliance with AS 2671 requires the machine builder to obtain explicit agreement from the machine owner before installing any form of filtration on the pump intake line, including a suction strainer.

This variance prompts the question: What insights does Car Lift Repair Tampa Florida possess that their ISO counterparts may lack? The concern arises from the potential adverse effects of poor inlet conditions, primarily attributable to a suction strainer, on pump longevity in the long term. This suggests that, notwithstanding the presence of contaminants and debris that ideally shouldn’t be in the reservoir in the first place, inadequate inlet conditions pose a more significant threat to pump life.

Please never forget to adhere to safety precautions that are listed in all of your manufacturer’s manuals.
