Water-Cooled Clutches Suit Demanding Enviroments

The Aquamakks range of water-cooled clutches and brakes from Wichita has been introduced for use in demanding sectors. These include mining, logging and forestry operations, metal processing and metal forming, oil and gas, water/wastewater and offshore/marine. Aquamakks are air, hydraulic or spring-set actuated units, integrating non-metallic composite water jackets and superior heat-dissipating copper wear plates that are optimised for heavy-duty continuous slip tension applications.

Available in sizes from 482mm (19in) to 914mm (36in), the units provide up to 2,535kW (3,400HP) of heat absorption. Designed with a series of alternating friction discs and water jackets, Aquamakks transmits torque by applying axial force from the pneumatic, hydraulic, or spring-set actuator, which provides accurate torque control for constant tensioning. The design features fewer parts for simple installation and maintenance, and a shim design that makes it easy to maintain and adjust for wear.

These features make Aquamakks suitable for field retrofits, rebuilds or new OEM applications, especially as adjustment for wear is easily accomplished by removing shims without any unit disassembly. The Aquamakks units are built with premium materials and finishes, with built-in corrosion protection. Water jackets are made from composite materials, so no optional salt-water corrosion protection is required. The water-jacket design ensures high heat absorption and torque stability, allowing for greater heat dissipation over similar sized units.

Aquamakks' mounting arrangement enables direct replacement, while requiring no design changes on the customer's behalf. Complementing the operation of the Aquamakks clutches and brakes, Wichita is offering the provision for electronic wear monitoring, as an aid to preventative maintenance. The company is also offering its Hico friction material, which provides up to 50 per cent higher torque on the clutch and brake units. Further options include custom-engineered solutions for adding accessories, such as deck-mount assemblies, water connection kits, shaft assemblies or covers.

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.
