Abstract

The invention discloses a hydraulic motor dragging system used for a load of high-power and a wide speed adjusting range. The hydraulic motor dragging system is arranged on a hydraulic pump and is characterized by being mainly composed of a hydraulic system and an electrical system. The hydraulic system is composed of a high-pressure ball valve (1.1), a low-pressure ball valve ball valve (1.2), a high-pressure oil-pressing oil filter (2.1) with an alarming function, a low-pressure oil-pressing oil filter (2.2) with an alarming function, a temperature sensor (3), a pressure sensor, a pressure gage, an energy accumulator (6), a servo valve (7), a hydraulic motor (8), a speed sensor (9) and a bypass valve (10). The hydraulic motor dragging system used for the load of high-power and the wide speed adjusting range has the advantages of being high in automation degree, good in maintenance performance, high in reliability, optimized in layout, capable of being conveniently operated by testers, and capable of ensuring reliability and safety of the testing process.
