Flow Cell Offers Cavitational Process Visibility

Hielscher Ultrasonics has added a glass flow cell designed for ultrasonic emulsifying to a range of accessories for its ultrasonic processors. The glass flow cell offers clear visibility of the cavitational process. The ultrasonic glass reactor vessel features two feed ports on the bottom side for the supply of the material into the reactor vessel. By the discharge port on the left side, the fluid exits the flow cell after passing the cavitational 'hotspot' generated at the sonotrode. In this hotspot, the medium is treated by the intense cavitational forces.

By this the various processes, such as homogenising, dispersing, emulsifying, sono-chemical and sono-catalytical effects, are achieved. With its two supply ports, the ultrasonic glass reactor is suitable for emulsification by ultrasonication as it can be fed with two immiscible fluids. The blue liquid marks the cooling jacket of the flow cell, through which a cooling or heating liquid can be pumped to control the processing temperature.

The glass flow cell can be adapted by a special flange to the sonotrodes of the UIP500hd, UIP1000hd, UIP1500hd and UIP2000hd. The processing capacity allows for flow rates of approximately 1 litre/min. The Hielscher glass flow cell is suitable for applications where the visibility of the cavitational process is of interest, such as during the testing of novel processes in research and development.

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.
