Abstract

Inventia se refera la o instalatie hidrostatica în circuit închis necesara actionarii rotorului portcupe ce echipeaza masinile de sapat santuri cu rotor. Instalatia, confrom inventiei, cuprinde doua pompe cu cilindree fixa care sunt cuplate pe rând sau simultan la doua hidromotoare prin distribuitoare realizeaza trei trepte de viteza, încarcarea, compensarea si racirea sistemului în circuit închis facându-se prin distribuitoare când acestea nu sunt comandate sau prin alte distribuitoare când primele sunt comandate. Schimbul de caldura în circuit închis si debitul pompei de împrospatare este realizat pe lungimea conductelor de legatura dintre distribuitoare si aspiratia pompelor.The invention relates to a closed-circuit hydrostatic plant required for the rotor-driven rotor drive machines. The installation according to the invention comprises two fixed cylinder pumps that are coupled in series or simultaneously to two hydromotors by means of three-stage dispensers, charging, compensating and cooling the system in closed circuit by distributing them when they are not controlled or by other distributors when first ordered. Closed circuit heat exchange and refill pump flow are performed over the length of the connection pipes between the manifolds and the suction of the pumps.
