Hydraulic Threaded-Body Work Support from ROEMHELD with Minimum Dimensions

For very versatile production processes, optimum positioning and clamping nowadays are the requirements for high-quality final products. Especially for applications with limited space the newly launched threaded-body work supports of the market leader for hydraulic clamping systems ROEMHELD offers an excellent protection against vibration and deflection during the machining of the workpiece.

The single-acting work supports (M26 x 1.5), designed for a maximum operating pressure of up to 350 bar, have a thin-walled locking bush in their body that circularly locks the movable support plunger when pressurising the element. The minimum distance of the support points is 30mm. The interior parts are corrosion resistant and the hardened contact bolt is specially sealed. The standard metallic wiper edge and the FKM wiper provide for high process safety.

Three types of function
The ROEMHELD work supports offer three different procedures for the contact of the support plunger. The work supports can be used with spring pressure, air pressure or oil pressure combined with spring force. When using the spring force, the support plunger is maintained by spring force in the extended position. When inserting the workpiece into the fixture, the support plunger is pushed back and contacts the surface to be supported with spring force. If the workpiece is clamped, the increasing hydraulic pressure locks the support plunger and thus forces in axis direction can be compensated.

When pneumatically pressurised the support plunger moves against the already clamped workpiece. The contact force can be adjusted by means of a pneumatic pressure reducing valve.

When pressurised by hydraulic pressure, a little bolt extends and the support plunger contacts the already clamped workpiece with spring force. Due to the increasing hydraulic pressure the support plunger will be clamped.

The work supports must only be operated with a sealed contact bolt. Special versions can be realised in cooperation with the ROEMHELD experts.

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.
