Hydraulic installation with main and sec. flow circuit and sec. flow filtration - comprises liq. tank with partition for limited screening of liq.flow into and out of tank.

摘要

In a first section of the liq.tank(1), the delivery conduit (1.3) to the sec. flow filter pump (3) is directly adjacent to the issuing leakage conduits (1.6,1.7),with the section partly screened from the remainder of the liq.tank. In a second tank section, the delivery conduit (1.2) for the main delivery pump (2) is directly adjacent to the return flow conduit (1.5) from the sec. flow filter pump. Both sections are well separated from one another. The liq. flow out of the return conduit (1.4) is screened from that out of the leakage conduits and the delivery conduit (1.3) by a dividing wall, with only partial screening. USE/ADVANTAGE - For hydraulic circuitry in complex installations,with increased purity of liq.supplied to the main pump,and improved filter effectiveness.
