DEVICE FOR PERFORMING UNDERWATER JOBS Russian patent published in 2002 - IPC

Abstract RU 2185995 C1

FIELD: performing underwater jobs in basins for machines equipped with hydraulic drives. SUBSTANCE: proposed device includes self-propelled chassis which holds working fluid tank, hydraulic motors and working equipment. Device is also provided with system for monitoring and maintaining excessive pressure in hydraulic equipment which includes reservoir charge with compressed gas and provided with pressure-reducing unit, additional reservoir pneumatically connected with working fluid tank. Working fluid tank is provided with pressure sensor for measuring the pressure above level of fluid in working fluid tank. Provision is also made for surrounding pressure sensor, unit for conversion of signals of both sensors and recorder. Space above working fluid level in tank is pneumatically connected with reservoir charged with compressed gas. EFFECT: enhanced operational reliability of hydraulic system. 4 cl, 1 dwg
