PUMPING STATION PLANT SPBE-C

SPBE C

General presentation

This system consists of wiring by students automated bearing plates associated to an operative part.

The operative part consists of a drinking water pumping plant of a small city.

It permits the visualization of the liquid flow in each stage of the process.

This system is conformed to the last securities standards.

 

Functioning principle

The extraction pump draws water from the ground water table and fills in an intermediate tank.

Two pumps start on successively. They draw the water from the intermediate tank to fill the water tower. Two valves situated under the water tower simulate the consumption of the families with return of water to the waste water.

 

Technical specifications

 

Description of the operative part:

The extraction shaft is simulated by a storage tank in PVC of 60 litres with a removable lid.

It could be drained by the extraction pump of 0.75 kW or with the general draining valve of the installation and discharge to the sewage.

The intermediate tank is simulated by a tank of 25 litres with tank vent pipe on the top. One face of the tank is transparent. It is equipped with a mini and maxi level detection by measure of water resistivity.

The discharge of water from this tank could be done by a manual valve or by two intermediate pumps providing the transfer to the water tower.

The water tower is simulated by a tank of 25 litres with tank vent pipe. One face of the tank is transparent. It is located at the same height than the intermediate tank and it is feed by the intermediate pumps of 0.37 kW each.

It is supplied with a mini, middle and maxi level detection, by measure of water resistivity.

It is drained by two manual valves simulating also the consumption of the users.

 

Description of the control part:

The electrical cabinet is an integral part of the system. It receive the bearing plate wired by the student.

We propose, in option, several sets of material allowing the student to wire this bearing plate:

- Set of material to wire, version relay,

- Set of material to wire, version Schneider Zelio PLC,

- Set of material to wire, version Schneider TSX37 PLC with PID level control.

All these sets of material are available in wired version on removable bearing plate.

The control cabinet also includes of a differential circuit breaker, a security limit switch on the cabinet door and a security logical block which allows the power putting of the bearing plate.

A device of fast securing and connectors allows a fast assembling of the bearing plate wired by the student.

 

Features :

Dimensions: length: 1400 mm – width: 630 mm – height: 1750 mm

Power supply 400 V + N + G 16 A

Total capacity in water: 60 litres

 

Teaching objectives

Further to the selected options:

- Study and wiring of an automatic system in version relays,

- Study and wiring of an automatic system in Zelio configuration,

- Study and wiring of an automatic system in TSX37 configuration,

- PID Level control (only with the TSX37 bearing plate),

- Frequency variation of the asynchronous motor (only with the TSX37 bearing plate),

- Detection of level by conduction,

- Control of the sizes of the installation: absence or presence of voltage (the system can be used for electrical authorization),

- Setting up and verification of the good working after realization of the wiring,

- Repairing and setting of the system (thermal protection, detection of level... )
