DEVICE FOR HIGH-PRESSURE DELIVERY OR FOR HOMOGENIZATION OF LIQUIDS Russian patent published in 2004 - IPC

FIELD: mechanical engineering. SUBSTANCE: proposed device contains homogenizer, drive motor with transmission mechanism consists belt drive, reduction gear and crank mechanism arranged in crankcase. Pumping section contains pumping unit, valves and pistons connected with crank mechanism. Transmission mechanism is designed for converting rotation created by electric motor into reciprocation of pump pistons. Drive motor is arranged on crankcase and is guarded from two sides by walls connected by means of cover. Walls form air pass channel together with cover to provide cooling of device drive parts by simple and effective method. Thanks to use of different devices peripheral relative to proposed device, air can be brought out of device and recirculated after cooling with provision of additional utilization of heat. EFFECT: enhanced reliability in operation. 7 cl, 4 dwg
