Development and Research of a Promising Pumpless Liquid Cooling System for Reciprocating Compressors

A new pumpless liquid cooling system for a single-stage two-cylinder reciprocating compressor has been developed from the analysis of work processes and systems compressors, where one piston compresses moves gas coolant in system. The intensification movement increases machine, which can reduce temperature cylinder–piston group increase indicator efficiency feed rate. mathematical model working its on basic fundamental laws conservation energy, mass motion. prototype was tested to obtain knowledge about machine confirm assumptions made while developing model. After series experiments, influence compressor, technical carried out each process, energy consumption characteristics with were established. There validation performed made. According processes, numerical experiment out, established: flow rate decreases an discharge pressure crankshaft speed when changes 0.4 MPa 0.8 MPa, decrease isothermal due leakage non-isothermal nature compression as well return process reverse expansion, leading more than 15%; equalization pressures cavities pressure, is reduced by (15 ± 17)%; angular 800 rpm 1500 rpm, 2.5 times, this hydraulic resistance velocity; range 1000 1200 maximum observed; supply ratio observed at mL/min 900 mL/min.
