Summary

DURING THE 20-25 YEARS WHERE PUMP RECIRCULATION SYSTEMS HAVE BEEN USED IN DENMARK IN CONNECTION WITH LARGE AMMONIA REFRIGERATION PLANTS, A GREAT NUMBER OF EXPERIENCES HAVE BEEN ACHIEVED, WHICH HAVE RESULTED IN A VERY LARGE RELIABILITY OF OPERATION FOR SUCH REFRIGERATION PLANTS. WHEN CONSTRUCTING THE PUMP SEPARATOR, MAKE SURE THAT IT CAN TAKE UP COMPLETELY THE LIQUID VARIATIONS ARISING DURING OPERATION OF THE PLANT. AT THE SAME TIME, WORK OUT THE DOWN PIPES SO THAT CAVITATION PROBLEMS DO NOT ARISE IN THE REFRIGERANT PUMP. FIT THE PUMP SEPARATOR WITH THE NECESSARY EQUIPMENT FOR MODULATING LIQUID SUPPLY, AND MOUNT SAFETY EQUIPMENT FOR HIGH AND LOW LIQUID LEVEL. THE REFRIGERANT PUMPS TO BE USED ARE TO BE OF A STURDY CONSTRUCTION WITH GOOD INLET CONDITIONS. PUMPS WITH A LOW NUMBER OF REVOLUTIONS SHOULD BE PREFERRED.
