GAMBARAN UMUM

The Computer Controlled Axial Flow Turbomachines Unit, "HMFAC", allows the study of single-stage axial turbomachines, with interchangeable vanes for the study of both a pump and a turbine.

The main part of the unit is the axial turbomachine connected to a computer-controlled asynchronous motor. This turbomachine can be equipped with different sets of rotors/impellers and different sets of stators/distributor vane systems, to form a pump or a turbine configuration.

The unit consists of a closed water circuit with a compensation tank and a computer-controlled centrifugal pump, which through the activation of the compensation tank by means of compressed air allows the conversion of the turbomachine without water loss.

In the turbine mode, the asynchronous motor works as a generator, and the centrifugal pump generates the flow and pressure during its operation. The power generated by the turbine feed to this centrifugal pump. In pump mode, the asynchronous motor works as a drive.

The transparent casing allows seeing perfectly the flow processes through the different configurations of impeller/rotor and stator/vane system. In order to obtain the speed triangles for the different vane shapes, values will be taken by means of pressure sensors connected to a head to measure the direction and speed in the flow zone directly upstream, between and downstream, depending on the position where said head is placed, of rotor and stator or of impeller and vane system, so that the pressure development in the turbomachine is recorded.

To remove the remaining air from the piping system, a computer-controlled ventilation valve will be used, or an automatic relief valve will act, which is activated by system overpressure.

It is possible to carry out a cavitation study due to the use of different pressure levels.

The motor shaft is equipped with a speed sensor that measures the number of revolutions. The power of the drive is determined by a tilting bearing, equipped with a force sensor for measuring the motor torque, on which the asynchronous motor is mounted.

Two manometers that measure the pressures at the inlet and outlet of the turbomachine are included and the differential pressure sensors measure the differential pressure in the rotor, the impeller/stator and in the system of distributed blades. A regulation valve allows adjustment the flow, which is measured through a flow sensor.

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
