1 phase to 3 phase VFD - Gozuk
1 phase to 3 phase VFD For Sale, Most Competitive Price, Fast Delivery, Custom Service, Wholesale 1 phase to 3 phase VFD, Made in China, High Quality Products!, China Variable frequency drive, VFD Supplier, Manufacturer.With a variable viscosity as stated the changing friction losses will likely not allow for holding both flow and pressure constant. You will need to choose 1 phase to 3 phase variable frequency drive (VFD) to control constant flow or constant preessure. As mentioned, if your gear pump was machined for the higher viscosity (greater internal tolerances) it will likely need to faster to maintain the same flow at the low end of viscosity. Are there any suspended solids expected. If so what size? How is it dissolved into solution (mixing tank prior to pump)? What is being used to control the 1 phase to 3 phase VFD?
For one product, if the temp. is constant >>> visc. is constant , with new gear pump,,, then, the closer cause of the flow variation is the speed variation. the question - as stated by Robbert - is: What is being used to control the 1 phase to 3 phase variable frequency drive?
there several product we are metering using this pump. Each product have a specific viscosity. The pump was selected for viscosities of 200 cPs to be metered, as well as other products with viscosities that could reach up to 1500 cPs. Before processing the temperature of the 1 phase vfd being pumped is brought to a ficed temperature, say 20 deg C, by means of temp controlled units. Im sorry if you got be wrong, but temp i.e viscosity is constant all through the process. visit our website for more.

VFD drives, also known as ac drives and VFDs, are widely used in HVAC systems, pumps and conveyors. An ac drive controls the rotational speed of an electric alternating current (AC) motor by adjusting both voltage and frequency of the electrical power supplied to the ac motor.
The efficient way of cutting down the electricity cost on these motors is to adjust the frequency or speed of operation for the ac motor when big power AC motor is being used. It is the general purpose of the variable frequency drives (VFD) being used for. Electric motors that do not adjust their frequency are limited to operate at the maximum frequency all the times, even when not so much power demand. The ability to adjust the frequency when less power is needed, and also can achieve full power running of the motor can improve efficiency, electricity savings, and optimize the motor-driven process. The energy savings from a frequency inverter can be dramatic, with common energy savings of fifty percent or more. Another advantage of using variable frequency drive is their ability to extend the speed range of the ac motor by being able to have adjustable frequency up to 4000 Hz rather than the normal maximum of 50/60 Hz. However, operation of motors at speeds above their rated operating speeds must be checked and approved by the motor manufacturer. Most ac drives are often programmable and allow the operator to select the conditions that are most suitable for their particular application.
