Meco Exhibits Seals For Dry-Bulk Process Equipment

Meco shaft seals for rotating dry-bulk process equipment will be exhibited at the International Powder and Bulk Solids Expo at PTXi in Rosemont, Illinois, USA on 4-6 May, 2010. New at PTXi this year is Meco's HB model seal for standard-sized screw conveyors and similar equipment. HB seals have many of the features used in Meco's custom shaft seals, but are in stock in five Cema and 11 metric shaft sizes - from 1-1/2 to 3-7/16in and from 40 to 90mm.

HB seals are designed to perform under 90 per cent of the typical operating conditions associated with screw conveyors or scrolls, even where waste pack housings, packed glands, lip seals or other seals fail. This includes food-grade applications, temperatures up to 500F (260C), abrasive products and vertical or inclined conveyor shafts. The HB accommodates up to 1/4in (6mm) of shaft run-out.

Capabilities of Meco custom-engineered shaft seals include: service in potentially explosive atmospheres; speeds to 1,000ft/min on dry-running shafts; holding vacuum in dryers, despite axial movement and thermal shaft growth; and sanitary seals that can be removed completely, sanitised and replaced, or for CIP systems.

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.
