Filling and venting of hydraulic indicating system

Installation

– continued –

Open both bottom valves before filling the hydraulic indicating system.
See drawing on page 4
. Use the operating device

E to open the bottom valves.

2. Loosen the venting plug

Q of the actuating cylinder H of the liquid phase in the operating device E

by half a turn.

3. To fill the hydraulic indicating system connect an external oil hand pump with a pressure gauge

(measuring range: 0 - 20 bar) to the filling connection

I of the bottom valve for the liquid phase.

Operate the pump until the oil leaves the venting plug

Q of the indicating cylinder H without any bubbles.

4. Then fasten the venting plug

Q tightly.

5. Continue to operate the external oil hand pump until the indicating piston

O is completely moved out

and a pressure of approx. 0 to 20 bar is indicated by the pressure gauge.

6. Finally remove the external oil hand pump from the filling connection

I of the bottom valve and open

the hydraulic system by loosening the tension rope. The bottom valve closes automatically.

Follow the same steps when filling the bottom valve for the gas phase.

Performance test
Use both operating devices

E for the performance test.

See drawings on page 4 and page 23
. To close the hydraulic system, pull the tension rope that closes the ball valve of the control unit

X

of the bottom valve HWV 25/ - DN 80.

2. Use the pump lever

F of the hydraulic hand pump T in the operating device E and perform approx.

six strokes until you detect a slight resistance. The indicating pistons

O of both bottom valves must now

be in the open position and they must be extended by approx. 46 mm.

3. During the hold time of approx. 2 hours the pressure must not decrease.
4. Check all connections and screwed unions for oil leaks. If necessary re-tighten the connections.
5. Then re-open the hydraulic system by loosening the tension rope.
6. Both bottom valves must close automatically and the indicating pistons

O in the operating devices E

must be at the lower position.
