Parker Hannifin, a provider of motion and control technologies, will show three hydraulic filtration products at Hannover Messe 2009 on 20-24 April.
According to the company, the products, which have been developed considering environmental matters, simplify the filtration process and integrate filtration solutions into hydraulic system assemblies.
At 414bar maximum working pressure and flow options up to 700 litres per minute, the World Pressure Filter (WPF) series incorporates eco-intelligent performance media that are intended to reduce disposal waste and cost by more than 50 per cent.
Parker Filtration offers hydraulic system designers the possibility to integrate various system functions into single components.
This can result in cost reductions for the application in manufacturing and end-user maintenance and can realise more compact solutions and lower environmental impact by reducing leak points, for example.
Integrating high-pressure filters such as the WPF with quality media and patented elements is intended to guarantee the quality of filter performance and to maximise system component protection.
The filtration media has been designed in a patent-protected element range, whose element design is claimed to reduce time to change and eliminate oil spillage during changeover as the element remains in the bowl when removed from the filter head.
The bowl of the WPF filter can be quickly removed as no tools are necessary and the integral element requires the minimum of space for removal, allowing the filter envelope to be kept to a minimum.
The WDPF high-pressure duplex filters include a solution to allow remote switching.
Instead of the manual operation of the main duplex valve and equalising line, Parker's hydraulic solenoid valve technology makes a safe and remote operation possible with the WDPF filter.
This process can be fully automated; when one filter element gets contaminated, the filter condition indicator provides a signal to the duplex valve unit for direct switching to the other filter with a new element.
At the same time, a warning signal is provided to the local overall system controller that one filter element requires replacement.
In general, before switching the duplex valve, an equalising line needs to be activated to avoid excessive pressure peaks when putting the unused filter element into operation.
This solution overcomes the risk of the traditional manual process where correct usage of the equalising line is not guaranteed, according to the company.
Excessive pressure peaks can result in the damage of system components and seals, causing unexpected standstill and maintenance to process equipment.
By using Parker's patented filter elements, the quality of filtration is also safeguarded.
Another solution that will be on show is the company's Icount Mini-Lab, which eliminates the need for laboratory sample testing.
The Icount Mini-Lab has been developed to remove the engineer's reliance on external laboratory services for accurate solid particle contamination analysis of liquids.
Consisting of an Icount bottler sampler (IBS), a laptop computer containing the Parker analysis software with a printer and all the necessary cables mounted in a transportable trolley, the Icount Mini-Lab provides similar accuracy to the sampling carried out in a professional laboratory.
Each device is supplied with 30 Parker oil sample bottles and provides a way for both original equipment manufacturers and end users to monitor contamination in their fluid systems on site.
Testing is carried out in three steps: a hydraulic fluid sample is obtained from the system to be tested; the fluid is sampled for three minutes in the IBS; and the analysis report is printed out immediately.
A three-minute test is normally enough to confirm how contaminated the sample of hydraulic oil is.
The IBS provides onboard, laser-based, particle-counting technology, a three-minute maximum test and an oil contamination report programme in one system.
It features an interactive touch screen, a pressurised bottle chamber via an internal compressor pump, a bottle cavity aperture design, a sample tube cleaning sleeve minimising contamination crossover and an internal printer.
The Icount Mini-Lab is an onsite contamination monitoring solution for engineers and maintenance personnel and provides reproducible results performance to ISO4409:1999 and NAS1638 particle count distributions.
