GENERATOR OF FLOW RATE OF WORKING MEDIUM |
摘要 |
FIELD: creation of circulation of working medium in installations for calibration of flowmeters with large conditional passages and of meters of amounts of liquid and gas. SUBSTANCE: generator of flow rate of working medium has pump and user of flow (flowmeter, engine) intercoupled by shaft. Flowmeter to be calibrated is installed in one of pipe- lines connecting pump and engine. Low-consumption auxiliary pump forces considerable flow to circulate in the circuit of pump and user of flow in which capacity pulse-free roller-blade machines are used. Optimal relation of working spaces <EMI ID=0.134 HE=9 WI=12 TI=CHI> of pump and user of flow is chosen within limits <EMI ID=0.135 HE=9 WI=48 TI=CHI>. EFFECT: simplified design, high efficiency, minimal losses when started from rest, capability to function under various operational modes. 8 dwg
