Some Aspects of Laboratory Testing of Two-Stage Reciprocating Compressors
نویسندگان
چکیده
The dynamic testing of a two stage reciprocating air compressor with interand after-cooling during the steady and transient state operation is reported and the encountered problems discussed. Measurements and recordings of the instantaneous temperature and pressure in cylinders, suction and discharge chambers and in the associated pipework and air-coolers were carried out together with the instantaneous torque on the compressor shaft. Specific account is given to the selection and calibration of adequate types of measuring transducers that would possess the desired dynamic characteristics, but also meet the mounting and strength limitations encountered in particular in case of testing of small compressors.

متن کاملDry Screw Compressor Performance and Application Range
Screw compressors have the advantage of low mechanical vibration levels similar to those found in centrifugal compressors due their rotary motion. However, screw compressors are positive displacement machines with a working principle similar to reciprocating compressors, which gives screws some advantages compared to centrifugals, such as: • The suction volume flow and power consumption grow li...
