Abstract

In een machine voor het verbrijzelen van betonoppervlakken door middel van hydraulisch opgetilde valhamers (2, 3, 4, 5) is een hydraulische accumulator (14) met voorspandruk op de drukzijde van een hydraulische pomp (12) aangesloten. De hydraulische accumulator (14) staat door middel van terugslagkleppen (18, 31) met de pomp en de hydraulische cilinders (7, 8, 9, 10) gelijktijdig in verbinding. Een tweede accumulator (30) is aangesloten aan de terugloopleiding naar het reservoir (27). Hierdoor wordt het rendement van de machine verhoogd en wordt het gebruik van meerdere valhamers (2, 3, 4, 5) mogelijk.In a machine for crushing concrete surfaces by means of hydraulically lifted drop hammers (2, 3, 4, 5) a hydraulic accumulator (14) with pre-tension pressure is connected to the pressure side of a hydraulic pump (12). The hydraulic accumulator (14) is connected to the pump and the hydraulic cylinders (7, 8, 9, 10) simultaneously by means of non-return valves (18, 31). A second accumulator (30) is connected to the return line to the reservoir (27). This increases the efficiency of the machine and allows the use of multiple drop hammers (2, 3, 4, 5).
