Hydraulic system
The primary motor runs the primary hydraulic pump, which draws fluid from the hydraulic fluid tank and pressurizes it. The
pressurized hydraulic fluid passes through the heat exchanger and the hydraulic filter to the primary hydraulic manifold,
which contains a shift valve that alternates the supply of hydraulic fluid to each side of a reciprocating piston in the
intensifier.
Inlet cutting water enters the high-pressure cylinder in the intensifier, where it is compressed by the piston to make
high-pressure water for cutting or piercing.
Hydraulic fluid from the hydraulic center section in the intensifier returns to the hydraulic fluid tank through the primary
hydraulic manifold.
The heat exchanger keeps the hydraulic fluid at its optimal temperature. A gear pump moves hydraulic fluid from the
hydraulic fluid tank and sends it through the heat exchanger, where heat is transferred through fins to cooling water or to
an optional fan. The hydraulic fluid passes through a hydraulic filter and then returns to the hydraulic fluid tank.
