Pipecutter Features Heavy Duty Linear System

Hepcomotion has revealed how its HDS2 heavy duty linear system has helped the Pipecutter from Messer Cutting Systems to cope with increased loads. Pipecutter is a plasma machine that was initially developed for the streetlamp production industry but is now used in other manufacturing sectors. The pipe profiling machine is built to specification to meet different pipe length requirements and can be equipped with a series of options to suit the application. These options include the incorporation of a drilling head, which naturally affects machine dynamics.

The increased loads involved require the incorporation of a heavier duty linear motion system and Hepcomotion said its HDS2 has proven a suitable solution. The basic purpose of the Pipecutter in its principle market is to cut an inspection door and cable entry into the street lighting column. Gary Buck, project manager at Messer Cutting Systems, said: 'Some customers additionally want to drill holes at different positions on the column to later mount fixtures.

'So we fit twist drill heads to the machine for that purpose,' he added. The standard Hepcomotion GV3 linear guide is suited to the task of carrying and positioning the plasma cutting head on Pipecutter. However, the addition of the twin drill heads pushes GV3 capacity. 'We needed a strong linear beam and slides that would easily withstand the extra loads and provide good positioning accuracy,' Buck said. This is vital to ensure there is no beam deflection and also good repeatability when drilling the fixing holes. The Hepcomotion HDS2 proved to be the suitable product. Hepcomotion's product range provides a selection of options and includes single-piece rings up to 1.8m in diameter.

This programme is complemented by the Hepcomotion MHD maximum heavy duty system whose bearing blocks each have a maximum load capacity of five tonnes. Also included on the Pipecutter machine are Zimm screw jacks - another Hepcomotion product - that support the tubes and provide height adjustment. Based around a cubic body and building block principle, the heavy duty jacks provide maximum lifting capabilities of up to 1,000kN.

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...

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...

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.
