Oilmiser Device Solves Hydraulic Reservoir Issues

The Oilmiser reservoir aspirator (ORA) from JLM Systems is designed to address two basic issues that affect all hydraulic reservoirs. The first of these is that outside air enters the reservoir through the air breather, whenever the fluid level in the reservoir falls, and the second is that internal fumes exhaust through the same air breather whenever the fluid level in the reservoir rises. The problem is compounded when the reservoirs are located in confined machinery rooms, in poorly ventilated work areas, in dangerous locations or where the air filter is seldom checked for proper functionality.

The ORA incorporates two independent and unidirectional flow passageways in one body. The vertical airway is called the inflow control gate (ICG), while the second passageway is called the exhaust control outlet (ECO) port. The ICG allows air to enter the reservoir through the tank air breather in one direction only, while preventing any exhaust air from venting back through the air breather. The life of an air filter, especially a desiccant air breather, is increased significantly when oil-contaminated fumes generated inside the reservoir cannot backflow through the tank breather.

The ECO port is also a unidirectional passageway. Internal fumes and gases can only exit the reservoir through the ECO port, while all replacement air can only re-enter through the ICG. The standard ECO port is a 1in NPT female pipe. The ICG on the basic ORA-1000 is protected by the Oilmiser 5-micron air filter and the company's high-visibility all-weather moulded cap. The standard air filter and cap can be replaced with a variety of optional couplers, offering a range of female pipe ports from 0.5in NPT to 2in NPT. Many hydraulic reservoirs and liquid storage tanks operate in extremely wet and contaminated areas or in locations with limited or restricted access.

For these reservoirs, clean air can be piped into the reservoir from a safe and clean location through the ICG. Internal fumes and gases, generated inside the reservoir, can be piped out of the work area via the ECO port and safely released to atmosphere at a remote location, or they can be further conditioned to meet local environmental concerns and safety regulations. The ORA is shipped fully assembled and ready for installation using the gasket and mounting screws supplied. In minutes, the ORA can replace conventional reservoir fillers/breathers that use a six-hole x 2.88in BC mounting pattern.

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.
