IP42 Protection Hydraulic Control System / Electric Hydraulic Control System

HYDRAULIC CONTROL PANEL (HCP)


The control panel for control valves consists of:

N° 2 SV proportional valves (steam and desuper. control valves), supplied with built-in electronic circuits

ON-OFF, two-position solenoid valves (EV), to perform emergency actions (fast opening < 1 sec)

accumulator

The HCP houses also analogue positioning cards (steam valves and desuperheating valves) for stroke control in closed loop system.

The response time of ON-OFF valves may be separately adjusted by suitable throttling devices.

The hydraulic circuit should be provided with gate valves to allow maintenance actions.

Complete cycles are allowed, when pumps are still, within 15 minutes from pump stop, because of leakages.

Options:

Hand pump

ON-OFF valves for fast closing < 3 sec


ELECTRIC CONTROL CABINET


The electric control cabinet is supplied with a redundant feeder/transformer for auxiliary circuits (240 Vac 24 Vdc), warning lights, lamps, contactors and any other necessary component to grant the efficiency of the whole hydraulic equipment.

The cabinet, fitted with a fan (extractor) complete with replaceable cartridge, includes an auxiliary electrical socket .

Manufactured according to the industrial standards, with minimum protection degree IP42, houses the control system for emergency solenoid valves and 1 PLC to manage the Hydraulic Power Unit, the Control Panel and the interchange signals with control room.

The cabinet houses also analogue positioning cards (steam valves and desuperheating valves) for stroke control in closed loop system.

Auxiliary circuits are separately protected, even when redundant (pumps control, PLC power supply and proportional valves).

Cable entry from bottom.

Max cable run from cabinet to control panel approx. 200 m.

Max resistance of proportional valves supply cable 2 W.

Approximate sizes 1200 x 2000 (+ 100) x 600 mm.

PLC CONTROL FUNCTIONS

The HPU is managed by one PLC, located inside the electric cabinet. The PLC manages failure and emergency signals as well as pump change-over.

The PLC is provided with display and keyboard allowing to check programmed parameters on site, and to modify them if required.

The access to parameter modification is protected by password.
