DISCHARGE DOOR HYDRAULIC PUMP

DISCHARGE DOOR HYDRAULIC PUMP

I. DISCHARGE DOOR:
Composed by discharge door and bearing. The gap between the mixing tank and the dicharge door
should be within 1-1.5mm. The discharge door should be cleaned periodically to prevent concrete
accumulation and ensure a smooth door operation.
II. HYDRAULIC CYLINDER:
Liner motion tank (single hydraulic cylinder), which is driven by hydraulic oil powered by hydraulic
pump through pressure-proof hoses.
III. HYDRAULIC PUMP:

Discharge door hydraulic powerpack is composed of motor, pump, cylinder, manual pump, dividing
valve, etc.. The hydraulic system shall work only at unloading phase. It shall not continuously work for
a long time. On power cut or emergency, it can be operated manually for urgent unloading.
Pressing the opening pushbutton, the correspondent solenoid in the solenoid valve is excited and the
pump stop is operated by the opening micro-switch placed on the discharge door rotation axis. Pressing
the closing pushbutton, the correspondent solenoid in the solenoid valve is excited and the pump stop
is operated by a pressure switch placed on the circuit. The closing micro-switch has to be used only to
indicate the position of the door and activate any automatic devices required. The motor of the pump
stops at each cycle end.

When changing the oil, completely drain the system including hoses to one or more cylinders.
