Any hydraulic oil, which bypasses the piston seals, is ejected via the breather hole on
earlier machines, on later machines the return hose directs this hydraulic oil back to
the tank and is much more environmentally friendly.
Hydraulic System Description – Batchweigher
The basic hydraulic system is modified when a batchweigher is fitted to include a
bleed valve, which is inserted into the circuit between the control valve and hydraulic
cylinder and adds an extra return line back to the tank.
The bleed valve is designed to ensure that when the hopper is fully lowered no
residual pressure remains in the circuit between the cylinder and control valve, which
could affect the batchweigher readings.
The bleed valve assembly contains a valve and spring and is ported to allow oil to
flow either to the hydraulic cylinder or to the hydraulic tank. (see the illustration)
On raising the hopper, hydraulic oil flows into the bleed valve body through the orifice
in the valve and out to the hopper ram. As the oil flows through the orifice under
pressure the valve is forced across the body compressing the return spring and
closing off the return port to the hydraulic tank.
On releasing the control lever to neutral during either the raising or lowering cycle,
hydraulic oil under pressure trapped in the line between the piston and control valve
spool holds the bleed valve against the return port seat. This prevents the oil
returning to the tank, thereby preventing the hopper from dropping.
Should the hopper continue to drop the seat/valve within the bleed valve assembly
possibly requires attention using the special tool. (see below)
If the system is operating correctly the hopper should remain stationary until the
control lever is operated.
On fully lowering the hopper, the reduction in pressure will allow the spring within the
valve body to push the bleed valve back across the body. This action opens the tank
return port allowing any residual oil/pressure trapped in the base of the cylinder to
return to the tank, thereby ensuring that the hopper is completely lowered, allowing
the striker to fully contact the loadcell ensuring the accuracy of the batchweigher
reading.
On assembling the bleed valve it is important that a good seat is formed within the
valve body using the special tool/punch part no. V2003698. The punch should be
inserted into the valve, shaped end first, and a seat formed by driving the punch
sharply down into the body using a soft faced hammer.
