Disc brake - Power unit CE8L 1 - PRESENTATION

1-2 Operating conditions

1-1 Use

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.

The hydraulic power unit CE8L (g.1) is intended to deliver an hydraulic pressure to open the emergency hydraulic brakes SH and TH.

Fig. 1 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 swi tched 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 pressure with the motor M stopped. If pressure lowers down to the minimum level, the switch closes and starts the pump motor M again.

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.

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.

Calipers are closed by means of a single solenoid valve EV1 (NO). For installations requiring a high level of safety, we advise the 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 .
