1 - PRESENTATION
1-1 Use
The hydraulic power unit CE8L (g.1) is intended to deliver an
hydraulic pressure to open the emergency hydraulic brakes
SH and TH.
1-2 Operating conditions
Working conditions:
- Ambient temperature: -10 °C to +60 °C
- Relative humidity ≤ 70 %
- Dust in atmosphere ≥ 65 µ
- Protection against vertically falling waters.
Other conditions, consult Stromag France.
2 - OPERATION
2-1 Flow diagram
See g. 5.
2-2 Principle (g. 5)
a) Opening of the calipers
When the hydraulic power unit is switched on, the solenoid valve
EV1 (NO) closes and the motor M starts simultaneously. This
motor drives the gear pump P1 which gives the oil pressure al-
lowing the hydraulic calipers to open.
The opening of the pressure switch CP1, included in the working
circuit, stops the motor M when working pressure reaches the
maximum set level. Then, the installation stays under pressurewith the motor M stopped. If pressure lowers down to the minimum
level, the switch closes and starts the pump motor M again.
b) Closing of the calipers and braking
Switching off the motor M and the solenoid valve EV1 brings
the oil back to the power unit reservoir and the pressure back to
zero. Calipers close and braking torque is applied.
c) Manual opening of the calipers
With the ow limiter LD1 closed, the hand pump P2 provides
the necessary pressure to open the calipers, in case of mains
failure or manual operations on the calipers.
Fig. 1
1-2 General characteristics
The CE8L hydraulic power unit is tted with a gear pump and a
motor of 2,2 kW at 1500 rpm for a nominal ow rate of 8,4 l/mn
(on network 50 Hz).
The maximal utilization pressure is 225 bar.
Frequency of operations = 100 operations / hour maximum
The caliper can be installed horizontally (CE8L-H) or vertically
(CE8L-V) (reservoir at the bottom).
See ow diagram g.5 and description g.6.
Calipers are closed by means of a single solenoid valve EV1
(NO). For installations requiring a high level of safety, we advisethe option OP1 (2 EV).
In additional, we recommend a device of permanent diagnosis
of the solenoid valves operation (CS2EV) which allows the
detection of a possible fault .
