Abstract

An oil-water filling converter comprises an oil cylinder, a water cylinder which is connected with the oil cylinder, an oil cylinder piston arranged in the oil cylinder and a water cylinder piston arranged in the water cylinder and a connection rod between the oil cylinder piston and the water cylinder piston; the diameters of the oil cylinder and the water cylinder are respectively a and b and ais larger than b; the connection part takes the shape of T and is provided with a seal ring and an air vent; the tail part of the water cylinder is provided with a water intake-outtake system. The reciprocation of the oil cylinder piston drives the reciprocation of the water cylinder piston to draw water and press water, thus turning the oil pressure into high water pressure; the pressure increasecan be adjusted by the proper adjustment of the ratio of a to b. The seal ring at the connection part of the oil cylinder and the water cylinder prevents oil from flowing into the water cylinder andthe air vent at the water cylinder exhausts during the water pumping, thus realizing the transfer of oil pressure to water pressure for high pressure water infusion to coal body and tests of water infusion to rock body in rock mechanical test. The oil-water filling converter has simple structure and easy operation.
