Modern industry needs far more from its suppliers than straightforward product sales. Instead, today’s technology providers must support their customers with accessible and targeted services that, for example, aid plant and equipment efficiency and reliability and minimise disruptive downtime.
One area where this is relevant is with gas-loaded hydraulic accumulators, which store energy or smooth out pulses or shocks when installed within a hydraulic system. A system with an accumulator can use a smaller pump because the accumulator stores energy during periods of low demand. This energy is available for instantaneous use, released upon demand at a rate many times greater than could be supplied by the pump alone.
Regular maintenance
When properly applied in a hydraulic circuit, accumulators can have a long and reliable life, but regular maintenance is critical in order to maintain production efficiency and control cost.
To minimise the risk of downtime, engagement with an accumulator service team that offers fast and efficient service will provide numerous benefits. These can help combat and even eliminate a number of potential technical and performance issues that can affect accumulators in service.
Selecting a competent supplier of accumulator services is paramount, and there are several factors to consider for those seeking comprehensive support. Only consider suppliers with a dedicated resource for accumulator services as this will help guarantee the necessary expertise and experience. When a hydraulic system begins to underperform or fail, it can prove extremely disruptive, so a professional support team is vital.
Legislation
New directives, including the Pressure Equipment Directive 2014/68/EU, place requirements on manufacturers and those who ‘place equipment on the market’ and national regulations require most accumulators to be independently checked and recertified on a regular basis. However, despite the financial and legal risk, it is estimated that 80% of accumulators in Europe are not fully compliant with legislation.
Parker Accumulator Service Centres
Parker Accumulator Service Centres have been established with certified Parker distributors to optimise customer systems by combining industry-leading products backed by quality service to deliver stress-free accumulator management, which maximises performance, efficiency and safety. With training and certification provided by Parker, Accumulator Service Centres offer detailed product knowledge and expertise. Customers benefit from services such as system improvement, as well as accumulator maintenance, recertification and pre-charging, complete with audits, scheduled inspections and replacements.
Integrated solutions
With locations across Europe, Parker Service Centres offer an integrated solution that combines products, services and technologies, whether on an in-house (at the Service Centre), mobile or onsite basis. With an in-house service solution, the accumulator is sent to the Service Centre, while for mobile solutions the Service Centre travels, with equipment, to the customer facility. For onsite solutions, a fully equipped container workshop is established on location.
Aside from preventing any loss of system performance or failure, support can help to protect employees from accidents. Moreover, compliance with legal requirements is assured, while warranty validation and preventative maintenance reduces downtime and increases productivity.
With regard to the use of original spare parts, tangible benefits include shorter inspection time and the reduction of complexity in logistics (tracking systems, data monitoring and recording) and documentation, both of which help to lower costs and save time.
The service utilises the Parker Tracking System (PTS) which helps schedule accumulator maintenance, providing automated notifications on inspections and replacement parts. In automobile MRO operations, appointing an accumulator service provider could also help to make the production performance fit for Industrie 4.0. Further potential asset management activities include energy and efficiency audits, risk assessment and servicing for safety equipment, and asset condition monitoring and prognostics (sensors).
The implementation of preventative maintenance, improved reliability, extended application possibilities and reduced total production costs are among the benefits available to hydraulic systems in production plants.
