PLC CONTROLLED PUMPING STATION-3 TANK

Teaching suggested applications*

- The equipment is delivery complete, instrumented with technical manual and practical work

- The system includes a tank and three return groups to feed the distribution tank (water tower)

- The buffer tank is fed by a stainless-steel centrifugal pump

- The water tower is supplied by 2 stainless steel centrifugal pumps

- Consumption is adjusted by 2 leak rate solenoid valves

- The cycle is managed by an industrial programmable logic controller

Description

- Study of the concept of a lifting unit

- Measurement of level parameters

- Pump rotation, maintenance management

- PID type control on frequency converter or TOR

- Programming on API

TECHNICAL DETAILS

The principle of the bench is to study the concept of a pumping station and to simulate the operation of a water tower. It is equipped with three reservoirs: the well, the buffer reservoir and the water tower. The objective will be to maintain a certain level of water in the two upper tanks. For this we have a pump (on variable speed drive), to supply the buffer tank. This comprises an analog level sensor and 2 level detectors: minimum and maximum.
In addition, two centrifugal pumps supply the water tower. This tank has 3 level detectors: minimum, intermediate, and maximum. The bench is fitted with a programmable logic controller for performing several functions. Students can select different regulation methods Digital or PID.
The bench is also equipped with a supervision computer by means of a touch screen with Didatec interface included.
The robust design of this equipment makes it perfectly suited for use in schools.
Its anodized aluminum frame with legs gives it great strength as well as great flexibility of integration into your premises. The manufacturing of this equipment meets the European machine directive.
