Pumps are very important in many different settings, from factories and businesses to homes. They are used to move water and other liquids from one place to another. However, traditional pumps that run at a fixed speed can save energy and money. A better option is to use a frequency drive pump, which is also called a variable frequency drive pump or variable frequency drive well pump. These pumps ...
But this flow control is best achieved by the pump speed instead of throttling the discharge valve. Throttling the discharge valve will usually lead to waste of energy and reduction in efficiency and reliability. ...
To achieve the lower flow rates, the pump ha to be “throttled back” with an actuator or valve to walk it back on its curve. This leads to unnecessary energy consumption, as the pressure required to force past the partially closed valve is wasted energy. Or, the generated head above the required system head, is all wasted energy. ...
Design flow: 50 MGD (230 MLD) Sludge Production: 89 t/day Application Equipment: FKC screw press with rotary screen thickener Old Mixer: Static mixer with throttling valve New mixer: 6” OPTIFLOC™ Flow: 130 IGPM (10 L/s) Sludge type: Combined primary and secondary Sludge Composition: 73% primary 27% secondary Waste paper: 0-10% ...
The refrigeration system includes four major processes: compression, condensation, throttling, and evaporation. The compressor compresses the refrigerant into a high-temperature and high-pressure liquid state. The liquid refrigerant is radiated to normal temperature and high pressure through the condenser, and then throttling and spraying into the evaporator ...
Balancing valves are throttling devices designed to regulate the fluid flow through hydronic components. ...
The range of linear motion control valves consists of globe valves, gate valves, diaphragm valves and pinch valves. The range of rotary motion control valves consists of ball valves, butterfly valves and plug valves. From this range, the ...

Given that there are up to eight critical boiler feedwater valves per HRSG, maintenance or replacement of these valves can be very expensive. ...
A pneumatically actuated valve. This is a great choice for a plant based valve where a good air supply exists, but not so easy if you need the valve to perform several functions. A diaphragm actuated, hydraulic controlled valve is the most common pressure reducing valve in city water systems and for good reason. ...
As an alternative option to pipe replacement, the use of pumps working as turbines, throttle control valves (TCVs), or pressure reduction valves (PRVs) can be used to reduce leakage. ...
That meant that the pump needed to be throttled, and a lot of energy was lost. In 2009, the situation deteriorated further because the process conditions changed once again. ...
Oxygen and carbon dioxide are stripped by the steam flow and vented through a calibrated orifice or a throttling valve. Deaerated water is collected in the storage tank so as to assure an adequate “Hold-up” time for the boilers downstream. Operating pressure in the deaerator is maintained by a self-actuated valve, or by a control ...
Natural gas flow has a valuable pressure exergy which is currently destroyed in throttling valves at exit of the gas fields. In the current study, this pressure exergy has been calculated for an actual case. ...
Further analysis and comparison were made for two decreasing throttling loss methods: using internal heat exchangers and using expanders instead of throttling valves. ...
