Petrochemical and Natural Gas Industries.
3.41
rotor
rotating male or female assembly, including rotor body, shaft and shrunk-on sleeves (if furnished)
NOTE See Figure 1.
3.42
rotor body
helical profile section on or integral with the shaft
3.43
rotor set
set consisting of both male and female rotors and, for dry screw compressors, including timing gears and thrust collars
3.44
seal barrier gas
clean gas supplied to the area between the seals of a dual seal arrangement at a pressure higher than the process pressure
3.45
seal buffer gas
clean gas supplied to the process (inboard) side of a seal
3.46
separation seal gas
supply of inert gas or air fed into the region between the seal and the shaft bearing or between the bearing housing and atmosphere
3.47
settle-out pressure
highest pressure which the compressor experiences when not running and after equilibrium has been reached
NOTE This can be a function of ambient temperature, relief-valve setting and piping-system volume.
3.48
shutdown point
preset value of a measured parameter at which automatic or manual shutdown of the system or equipment is required
3.49
slide valve
device integral to the compression chamber for varying the volumetric flow through a rotary screw compressor
NOTE See Figure B.2, item 8.
3.50
soleplate
plate grouted to the foundation, with a mounting surface for equipment or for a baseplate
3.51
special-purpose application
application for which the equipment is designed for uninterrupted continuous operation in critical service and for which there is usually no installed spare equipment
3.52
special tool
tool which is not a commercially available catalogue item
3.54
thermal relief valve
valve for relieving pressure caused by thermal expansion of liquid within a closed volume
3.55
trip speed
rotational speed of the power-input rotor at which the independent emergency overspeed system operates to shut down a prime mover
NOTE For the purposes of this part of ISO 10440, the trip speed of alternating-current electric motors, except variable- frequency drives, is the speed corresponding to the synchronous speed of the motor at maximum supply frequency.
3.56
unit responsibility
responsibility for coordinating the technical aspects of the equipment and all auxiliary systems included in the scope of the order, including responsibility for reviewing such factors as the power requirements, speed, rotation, general arrangement, couplings, dynamics, noise, lubrication, sealing system, material test reports, instrumentation, piping, conformance to specifications and testing of components
3.57
vendor
supplier
agency that supplies the equipment
NOTE The vendor can be the manufacturer of the equipment or the manufacturer’s agent and normally is responsible for service support.
3.58
witnessed inspection witnessed test
inspection or test where the purchaser is notified of the timing of the inspection or test and a hold is placed on the inspection or test until the purchaser or his representative is in attendance
4 General
4.1 Pressure design code
The pressure design code shall be specified or agreed by the purchaser. Pressure components shall comply with the pressure design code and the supplemental requirements in this part of ISO 10440.
4.2 Unit responsibility
The vendor who has unit responsibility shall ensure that all subvendors comply with the requirements of this part of ISO 10440.
4.3 Units of measurement
The purchaser shall specify whether data, drawings, hardware (including fasteners) and equipment supplied for this part of ISO 10440 shall use the SI or USC units.
NOTE Dedicated datasheets for SI units and for USC units are provided in Annex A.
