PROCESS TESTING QUALITY OF FUEL AND GEAR FOR ITS REALIZATION Russian patent published in 2000 - IPC

FIELD: running of wheel-crawler machines, test of quality of fuel while equipment is stored or maintained. SUBSTANCE: sample of fuel is taken from tank of machine, presence of water and mechanical impurities is found and used to evaluate its correspondence to standard. In addition density and color of fuel are determined with the aid of portable device connected to tank of machine. Quality of fuel is tested continuously without preliminary drainage of fuel-sediment right after device is set to operating condition. If mechanical impurities or water ( sediment ) are found in fuel these sediments are drained till fuel corresponding to standard is obtained without disconnection of device from tank. Then volume of fuel present in device is returned into tank and quality fuel in volume equal to drained volume is added. Portable device for realization of process includes drain hose with tip and additional union linked to inlet cock located on lower lid of clear colorless case that includes three communicating chambers. First chamber houses oil densimeter, second chamber includes hydrometer and third inspection chamber is intended for detection of mechanical impurities, transparency and color of fuel. Upper lid of case has two holes above chambers with oil densimeter and hydrometer and outlet cock with hose. EFFECT: integration of technological process ensures saving of fuel and test time. 3 cl, 1 dwg
