OPERATION

Electronic Variation Speed is a feature of the asynchronous motors on MULTi-HE centrifu-gal pumps.The aim is to regulate the speed of the alter-nating current motor by converting the voltage and frequency of the 220 - 240 V, 50 or 60 Hz, single-phase network, into a system of three-phase voltages of variable frequencies and amplitudes.The frequency converter can thus be used to control the speed of the motor.This simultaneous action concerning frequency and voltage is carried out via two main elements : - A diode rectifier - A Pulse-Width Modulated (M.L.I.)

inverter

The rectifier is a diode bridge. The alternating voltage that crosses this diode bridge is converted into a «rectified» current. At this stage, in order to improve the quality of the voltage at the rectifier outlet, a set of capacitances and induction coils eliminates the slight residual waviness that emerges from the rectifier. We thus obtain a smoothed direct voltage referred to as the "DC bus".Following this change, the inverter will per-manently regulate the voltage at the variable voltage regulator outlet in order to optimise the magnetisation of the motor. The fixed voltage at the inverter input is converted into variable voltage via transistors. This principle is called Pulse Width Modulation (MLI).

These transistors are controlled by the microcontroller, which may or may not acti-vate them, thus allowing for the variation of frequency at the variable voltage regulator outlet.The transistors (IGTB: Insulated Gate Bipolar Transistors) thus operate in swit-ching mode and act as switches to convert direct voltage into variable voltage. The frequency of activation or switching of the IGBTs allows for the creation of variable magnitudes of voltage and frequency. This frequency must be high in order to eliminate the noise generated by the magnetisation.

Mode 1 and Mode 3: M13

Mode 1 and Mode 3: M13

Mode 1 : The pump is installed like a MULTi-H stan-dard pump, but its speed can be regulated manually, which allows it to operate over a range of flow rate/pressure curves.

Mode 3 : The frequency is varied by an external control. The powering on, stoppage and rotation speed of the pump are controlled by a 0-10 V or 4-20 mA input signalw.

MULTI-HE MONOPHASÉ

OPERATION IN MODE 2: M2OPERATING MODES : 3 operating modes are possible depending on the application and the requirements, through a choice of 2 product references (M13 - see page 3 - and M2).

Mode 2

Pump mode alone for pressure regulation. The pump is installed with its pressure sensor which can be attached to the pump or to the delivery pipe. The set point pressure value is regulated when the module is installed using the potentio-meter on the side.

Operation: When the actual pressure, measured by the sensor, drops below the setpoint pressure, the pump starts up and regulates its speed in order to achieve the setpoint pressure. The pump stops automatically when it detects a zero flow rate and if it is equipped with a low-water protec-tion system (optional).

Une pompe est représentée par un réseau de courbes correspondant à différentes fréquences (Hz) et donc à différentes vitesses de rotation du moteur. La fréquence est exprimée en %.

Une pompe V.E.V. est représentée par un réseau de courbes, sachant que toutes les courbes situées entre la et la sont couvertes.

En variation de vitesse, la puissance consommée est adaptée au besoin Q / H requis, engendrant ainsi de fortes économies d'énergie.

Le NPSH d'une pompe MULTI-HE varie en fonction de la courbe sur laquelle on se place. Il est donc important de connaître la pression de consigne souhaitée, surtout pour des installations de pompes en aspiration sur un puits, et de tenir compte du NPSH de la pompe à fréquence maxi, c'est-à-dire à 100%. La hauteur d'aspiration maxi, pour ce type de pompe ne doit pas dépasser 1 mètre.

L'intérêt de la variation de vitesse est une nouvelle fois ici démontré à travers le rendement puisque le rendement est optimal sur une grande plage de débit, par rapport à une pompe à vitesse fixe.

PUMP PERFORMANCEPUMP PERFORMANCE CALCULATION TIPSA pump is represented by a network of curves corresponding to different frequencies (Hz) and thus to different rotation speeds of the motor. The frequency is expressed as a %

An EVS pump is represented by a network of curves, with the understanding that all of the curves between 1 and 6 are covered.

With speed variation, the power consumption is adapted to the required Q/H, thus resulting in significant energy savings.

The NPSH of a MULTI-HE pump varies according to different curves. Therefore, it is important to know the desired setpoint pressure, especially for pump installations in suction mode in wells, and to take account of the NPSH of the pump at max. frequency, i.e. at 100%. The max. suction head for this type of pump must not exceed 1 metre. Here, the benefit of speed variation is once again demonstrated in terms of efficiency, as there is optimal efficiency over a wide range of flow rates, compared to a fixed-speed pump.
