Compact Spiral Hose For Industrial Machinery

Parker Hannifin has launched a flexible compact spiral hose for use in both stationary and mobile industrial machinery in a range of applications, including construction, defence and oil and gas. Offering 5,000lb/in2 and 6,000lb/in2 hose performance in a compact design, the new Compact Spiral improves productivity for original equipment manufacturers and end users with greater routing, installation, durability, size and weight advantages over conventional SAE spiral hoses, saving on material, shipping and inventory costs, according to the company.

The new hose technology can achieve two million impulse cycles - two times the ISO 18752-DC standard and four times the SAE requirement. This translates to a longer service life in nearly all applications, particularly those where many repeat cycles occur within a short timeframe, such as in injection moulding machines. The new Compact Spiral is claimed to offer a number of other benefits, including greater flexibility, a smaller outside diameter and a tighter bend radius thanks to a high-performance inner tube that makes it possible to refine, redesign and reduce overall hose construction.

For example, the hose has half the bend radius and a 30 per cent smaller diameter than conventional SAE spiral hoses. It also requires one third less effort to bend, meaning that bends can begin sooner, reducing the total amount of hose needed by 20-55 per cent depending on the application. The Compact Spiral is easier to route and install and more hose can be routed into tight quarters where larger-diameter, less flexible hoses simply would not fit. Customers can also jump up to a larger hose size to achieve better flow characteristics for their hydraulic systems while maintaining an outside diameter similar to the smaller hose that was previously installed; for instance, the outside diameter of a -12-size Compact Spiral equates to the diameter of a -10-size comparable SAE hose.

The new hose weighs up to 26 per cent less than standard spiral hoses, according to Parker. This weight reduction leads to fuel savings for equipment with many hydraulic hoses, such as car carriers and refuse trucks. In addition, shipping and packaging costs are reduced. The new 787TC (5,000lb/in2) and 797TC (6,000lb/in2) Compact Spiral hoses are available in sizes -8, -10, -12 and -16 and are backed by the company's network of manufacturing, sales and customer support centres.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
