Valve actuation for solar plant
09 June, 2009The Andasol 1 plant in the Spanish province of Granada is a parabolic trough power plant and is claimed as the world’s largest solar power plant. Intelligent electric actuators with digital control have been specified for valve control in all areas of the generating process.
Compact cylinder
07 April, 2009 byThe Two-Flat version of Metal Work Pneumatic’s Compact and ISO/VDMA cylinders is now available. The Two-Flat cylinder uses a piston rod with two longitudinal flat surfaces that is guided by a matching, sintered-bronze bush to stop rotation. This means that anything fixed to the rod will not rotate and it will resist any torque applied within the limits specified. A special polyurethane seal prevents the accumulation of dirt.
Rotary vane actuators
01 April, 2009 byThe VRX rotary vane actuators from Tolomatic deliver up to 54.7 Nm of torque at 100 psi (6.9 bar) and can withstand high axial loads of up to 102 N. These pneumatically operated rotary vane actuators are designed for use in material handling, part feeding and clamping, pick-and-place operations, cutting and many other industrial automation applications requiring rotary motion.
Linear actuator
15 March, 2009 byThe MXB-U belt-driven linear actuator from Tolomatic features an unguided carriage system that is capable of velocities of up to 500 cm/s and accelerations of up to 3000 cm/s2.
Belt-driven actuators
14 March, 2009 byThe MXB-P belt-driven linear actuators from Tolomatic feature a profiled rail guidance system that allows large moment loads, high-speed operation and high precision. With a carriage that employs THK Caged Ball bearings, the MXB-P linear actuator is capable of velocities of up to 3810 mm/s and accelerations of up to 30.48 m/s2. MXB-P belt-driven actuators are suitable for multi-axis applications such as test stations, product handling, laser marking, material cutting, adhesive dispensing or applications that require high linear velocities and accelerations, long stroke lengths and high duty cycles.
Test kit eases verification of sensor functionality
10 February, 2009A company has developed a portable test kit for the CAN protocol versions of its off-highway M-series linear position sensors to assist cylinder manufacturers and equipment OEMs in the off-highway market to verify functionality of the sensors after they are installed.
The hydraulics of wind power
08 December, 2008Companies like AVN Energy, a Danish manufacturer of wind-power equipment, are creating the technology which now provides 20% of Denmark’s electricity production. AVN co-operated with The Trelleborg Group’s Sealing Solutions to develop seals for their wind power actuators.
Compact cylinders
01 November, 2008Metal Work Pneumatic has expanded its product range to include a Two-Flat version of its compact cylinders.
Cylinder takes the stress out of bridge project
10 October, 2008It looks like a menacing multi-barrel cannon of the type slung beneath fighter jets, but the purpose of this dark cylinder is constructive, not destructive. The Enerpac 900-tonne hydraulic stressing cylinder, supplied and customised by Jonel Hydraulics, will be used by Post Tensioning and Grouting to simultaneously tension dozens of high tensile stressing strands for bridge sections of the $NZ250 million-plus Tauranga Harbour Bridge crossing in New Zealand.
New process makes biomass conversion system viable
29 September, 2008Gold Coast company Knetic Renewables plans to bring a new dimension to the renewable energy sector, converting waste products and the power of ocean waves to electricity.
Rotary indexing table
05 September, 2008The DHTG Pneumatic Rotary Indexing Table features high load capacities and precision. The table was designed for use with semi-automatic machines and work-piece buffers that require small rotary tables for their swivelling and separator functions.
Shock absorbers
05 September, 2008Absorbing the energy produced by moving masses, especially at slow speeds, has long been an issue for machine designers. A shock absorber with a design that absorbs energy at slow speeds has been developed by SMC.
Stopper cylinder
05 September, 2008The DFST stopper cylinder has a load range almost three times higher than Festo’s previous model.
Actuator designed for opening emergency doors
11 August, 2008Modern aircraft manufacture is fiercely competitive. There is immense pressure on to keep costs low. Requirements for efficiency and environmental considerations for wide-bodied aircraft demand research and innovation from every conceivable field. A Bavarian scientific and industrial consortium is breaking the mould in the construction of aircraft doors and emergency opening systems, aiming to develop a pyrotechnic rotary drive system for the task.
Electro-pneumatic transducer
08 August, 2008The Series EPTA electro-pneumatic transducer converts an analog input signal to a linearly proportionate pneumatic output by modulating its control valves to regulate branch pressure. All models incorporate two low-voltage valves, an integral barb filter, an analog 30-psi (200 kPa) gauge, an anodised aluminium manifold, and brass barbed fittings.
