Master Chemical Unveils Minimal-Foam Concentrate

Master Chemical Europe has introduced the Trim VHP E820 minimal-foam cutting and grinding fluid concentrate. According to the company, the concentrate does not foam, even at pressures greater than 150bar and when diluted with soft water. This stable product has been formulated specifically to meet the requirements of European Union manufacturers and does not contain any chlorine, sulphur, boron or formaldehyde donors.

Trim VHP E820 is suitable for the production of aerospace parts - a benefit that is confirmed by Pratt and Whitney approval. It is also said to be ideal for operations that use high-pressure, high-volume coolant. It maximises the benefits of through-the-tool coolant delivery systems on vertical and horizontal machining centres and will help achieve the best productivity from creep-feed and Viper grinders, according to Master Chemical.

This clean emulsion reduces carry-off for a low total operating cost and permits fast wetting for lubrication and the corrosion protection of the workpiece. Compatible with all metals and many non-metallic materials, this new coolant can run at lower concentrations for higher-speed operations where heat removal is a key issue. Higher concentrations are recommended on soft materials and for lower-speed operations where the friction, reduction and control of built-up edges are critical.

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.
