Edwards Supplies Pumps To Car Manufacturer

Edwards has won an order with a major car manufacturer to supply compact XDS35i dry scroll pumps. The pumps provide high vacuum in a reliable fit-and-forget system, enabling users to reduce the time and costs associated with maintenance. During the automotive manufacturing process hydraulic and brake fluids are installed under vacuum, which ensures that no air enters the system. The pumps are being used to provide the required vacuum in brake line evacuation.

The dry XDS35i dry scroll pumps are replacing oil-sealed rotary vane pumps in this application, as the dry pumping technology is said to provide benefits over traditional 'wet' technologies. The XDS design means that the bearings are isolated from the vacuum so no bearings, bearing purges, grease or oil are under vacuum and, as a result, the pump is virtually maintenance free. The XDS is also an environmentally friendly choice as there is no oil to dispose of.

Another advantage of the XDS is that it maintains vacuum at levels during high-humidity months. It provides flow rates up to 35m3h-1 and ultimate vacuum of 1 x 10-2mbar. An inverter drive controls the motor characteristics, which ensures that the pump always runs at optimum speed and allows the user to control the pump remotely.

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.
