High interest in hydro-pneumatic accumulator online course

High interest in hydro-pneumatic accumulator online course

HYDAC Australia is well pleased with the enthusiastic response to its new online hydro-pneumatic accumulator course since advertising on its website and Eventbrite 

Enrol now! 

Just as news of it hit via an article in Manufacturers’ Monthly, Ainsley Mirtschin from Perrott Engineering contacted HYDAC for more information on the course, followed by many other enquiries, revealing just how strong interest is in the course.

The course, which can be undertaken anywhere in the world, spans four hours at a cost of AU$350. It is a natural extension of HYDAC’s focus on training excellence, as already recognised for the second time in 2020 by the Australian Business Awards

“It’s the first of our offering in the online sector and it’s part of a strategic plan to make many of the courses, many of the learning possibilities, more accessible to a broader group of people,” HYDAC Managing Director Mark Keen comments.

“The expectation in the future is that people will study more at their own pace in their own time when they’re able to focus. 

“I think this is a really good chance for us to be offering these types of solutions. We hope that by doing so we will encourage people to participate in learning that they might otherwise be hesitant to dedicate time to just because it’s accessible. And hopefully, they will also look to further courses and further learning from that point on once their interest has been incited.”

Course structure

The course, a detailed examination of hydraulic accumulator technology, explores all aspects of hydro-pneumatic accumulator construction and operation within a system and its servicing.

“This exploration is not to be sneezed at taking into account the critical and multifunctional role hydro-pneumatic accumulators (pressure vessels) play in hydraulic oil systems, especially the fact that they can endanger personnel and equipment if not correctly engineered and maintained,” a HYDAC spokesperson says. 

Mr Keen underscores that the content in this course receives first priority over delivery method and that much care is and will be taken to ensure it remains “extremely valid, constantly refreshed, renewed and current”. 


Accumulator construction

The course kick-starts with an accumulator introduction (13 minutes) and a balloon demonstration (seven minutes). This is followed by information on general safety (one minute); the history of accumulators (12 minutes); the construction of bladder accumulators (nine minutes); the construction of diaphragm accumulators (10 minutes); the construction of piston accumulators (20 minutes); and the construction of metal bellows accumulators (three minutes).


Servicing bladder accumulators

The disassembly side of the course focuses on degassing (two minutes); removing the fluid pot (three minutes); and removing the bladder (two minutes). The reassembly side focuses on inspection and preparation (five minutes); installing the bladder and fluid port (two minutes); and fitting the seals and final assembly (six minutes).


Thermodynamics and calculation

This section starts with part one on thermodynamic processes and definitions (16 minutes); and next off temperature compensation for a gas pre-charge, with a calculation example (three minutes). This is followed by part two on thermodynamics, with calculations (10 minutes); and then the adiabatic process, with a calculation example (three minutes). 


Safety and certification

The accumulator safety equipment part of the course directs attention to safety equipment for accumulators (nine minutes), and isolating an accumulator using a safety block (two minutes). The design approvals, certification and inspections part of the course directs attention to certifications and approvals (16 minutes), and accumulator in-service inspections (18 minutes).


Other sections of the course from application limitations to testing and charging of accumulators

Other sections of the course include application limitations (11 minutes); use of ASPlight (five minutes); causes of bladder failure (11 minutes); pulsation damping and shock suppression (13 minutes); and transport and storage (eight minutes). 

Just before the end, testing and charging of bladder accumulators (seven minutes) and diaphragm and piston accumulators (five minutes) grab attention before the concluding part on accumulator stations.


Final section of course

The final section hones in on accumulator stations (six minutes); a backup bottle system simulator (four minutes); and accumulator station arrangements (30 seconds).

HYDAC Managing Director Mark Keen comments: “Businesses are short-staffed, everybody is short-staffed; sometimes there isn’t the luxury of letting people go for a week to do a training course. Affordability needs also have to be met when people want to avoid accommodation and travel fees. And then there’s pushback because of COVID-19, with some fearing face-to-face situations or crowded travel.”   

This makes the online course an ideal fit for some, with many other formats on offer from face-to-face, remote, virtual and augmented reality as well as flexible modules catered to learner requirements. 

Mr Keen adds that HYDAC “will be adding on new courses and content as it continues to look at how it can improve and enhance its offering”.
