2.3.2 Hydraulic System
1. Melting Tank
The adhesive is melted by heaters in Teflon–coated tank, in order to avoid
adhesive inside tank getting charred on the wall and change adhesive inside tank
easily. There are some fins set in the internal wall of tank to increase melting rate.
Temperature control is accomplished by means of the k-type (RTD) sensor
mounted at the bottom of the tank, to detect the temperature and transfer into
signal to pass to temperature controller.
2.Gear Pump
The gear pump of HS2510-N applicator is installed at the bottom of the tank,
which be driven by the 3 phase motor, through gear and chain to drive the
driver shaft of this gear pump, and the speed-alteration of the gear pump is
controlled by an inverter as shown on figure 2.6.
While the gear of the driver shaft rotate as the clockwise to drive the gear
which meshed with it, so the hot adhesive of inlet(glue flowing in) will be
pressed by gear and flow to the manifold. Then due to the atmospheric
pressure and the section produced by the rotary gear pump the hot adhesive in
the tank will be replenished to inlet (glue flowing in).
All gears in this system are spur gears.
