Is Dresser-Rand part of Siemens?
Dresser-Rand, acquired by Siemens in the same year as the lightning strike and now a part of Siemens Energy, Inc., is one of the world’s leading suppliers of reciprocating compressors.
What happened to Dresser-Rand?
In 1987, in a joint venture with Ingersoll-Rand the Dresser-Rand Company was formed. It continued under that name until 2015 when it was purchased by Siemens. In early 2018 the company’s government business was acquired by Curtiss-Wright and it was announced shortly after that the Wellsville plant would close in 2020.
How do you calculate reciprocating compressor capacity?
In general the capacity of the compressor is given by the formula:
- Capacity = Π * D2 * L * N * n/4.
- R = Absolute suction pressure of the refrigerant/ absolute discharge pressure of the refrigerant.
- V = Actual volume of gas sucked by the compressor/ Theoretical volume of the compressor.
What is capacity of compressor?
Compressor capacity can be defined as the amount of air the unit is able to pump out. While a small and large compressor can have the same pressure capabilities, the larger model has a greater capacity to produce more compressed air. Capacity is expressed in terms of cubic feet per minute (CFM).
How do I calculate my compressor?
The general formula used to calculate this is expressed as compressor time on/ (time on + time off) = Duty Cycle percentage. For example, if a compressor is said to use a 100% duty cycle, that would mean that the compressor provides 25 CFM and 125 PSI for 100% of the time it is in use.
How does a Gimpel valve work?
The OOTTV is designed to use hydraulic pressure supplied by the turbine control oil system to compress a fully enclosed, large diameter trip spring. This trip spring allows an OOTTV to typically produce four to 10 times the closing force of a mechanical latch-type trip throttle valve during tripping.
Who bought Dresser Industries?
General Electric Co.
In February 2011, General Electric Co. agreed to buy oil-field equipment maker Dresser Inc. for $3 billion, expanding its biggest industrial unit. GE acquired Dresser from funds managed by Riverstone Holdings LLC and First Reserve Corporation.
Is Dresser Rand Olean NY closing?
Siemens took over the former Dresser Rand facility and announced the closure back in February. The company says it will be offering 100 people the chance to work at facilities in Painted Post, New York, or in Houston. Olean Mayor William Aiello said in February, “This is affecting families.
Which type of compressor has highest capacity?
This process of slowing the radial movement of the refrigerant converts the kinetic energy to potential energy in the form of pressure. Centrifugal compressors have the largest capacity and are well suited for compressing large volumes of refrigerant.
How many horsepower does a Dresser Rand Compressor have?
Dresser-Rand offers seven different models with horsepower (hp) ranges from 200 to 11,000 hp (149 to 8,203 kW), allowable rod loads from 15,400 to 90,000 psi, rated maximum speeds from 850 to 1,800 rpm, and pressures up to 8,000 psig. Most compressors produce more capacity than needed to allow for process control.
Who are the leading suppliers of reciprocating compressors?
As a leading supplier of reciprocating compressors, the Dresser-Rand business offers products ranging from medium to high-speed separable units driven by engines or electric motors, to large, slow speed motor driven process reciprocating compressors.
Who is the parent company of Dresser Rand?
Lightning strike sparks a major machine upgrade using Siemens Motion Control Technology, plus lots of Siemens teamwork Dresser-Rand, acquired by Siemens in the same year as the lightning strike and now a part of Siemens Energy, Inc., is one of the world’s leading suppliers of reciprocating compressors.
What kind of software does Dresser Rand use?
To program all of these devices, Dresser-Rand employed Siemens Totally Integrated Automation (TIA) Portal, a common software engineering framework as well as a source of digital simulation tools and transparent production operations.
