A diving regulator or underwater diving regulator is a pressure regulator that controls the pressure of breathing gas for underwater diving.The most commonly recognised application is to reduce pressurized breathing gas to ambient pressure and deliver it to the diver, but there are also other types of gas pressure regulator used for diving applications.
The Kona Electric is a battery electric version of the Kona. It is the second electric car from Hyundai after the Ioniq. Sales started in Korea and Europe in 2018, with a market debut in the United States in 2019. [27] [28] [2] Kona Electric was available in two battery capacities: 39.2 kWh and 64 kWh. [29]
Examples are a voltage regulator (which can be a transformer whose voltage ratio of transformation can be adjusted, or an electronic circuit that produces a defined voltage), a pressure regulator, such as a diving regulator, which maintains its output at a fixed pressure lower than its input, and a fuel regulator (which controls the supply of ...
Organizational, or O-level maintenance occurs at the organizational unit level, for example by a single maintenance squadron as part of an aircraft wing. O-level maintenance is typically optimized for quick turn-around, to enhance operational availability.
The New York Times gave an example of "machinery that is not lubricated on schedule" that functions "until a bearing burns out." Preventive maintenance contracts are generally a fixed cost, whereas improper maintenance introduces a variable cost: replacement of major equipment. [13] Main objective of PM are: Enhance capital equipment productive ...
Unsuitable regulator design and construction: Any design feature that reduces heat transfer between the regulator and surrounding water, such as plastic trim, can increase the risk of freezing. Regulators that are suitable and have been tested for cold water use will mention this in the specifications. High flow rates through the regulator.
Drawing of a centrifugal "fly-ball" governor. The balls swing out as speed increases, which closes the valve, until a balance is achieved between demand and the proportional gain of the linkage and valve.
Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of equipment, systems, machineries and infrastructure. Since the Industrial Revolution , devices, equipment, machinery and structures have grown increasingly complex, requiring a host of personnel, vocations and related systems needed to maintain ...
