Q1, Which turbine should I choose?
Please tell me the water head, flow rate, frequency, Total power
you need
, voltage, on grid or off grid operation, we will propose a
solution.
Q2, Can your factory provide all the equipment for hydropower
generation?
Yes, we can provide you with turbines, hydro-generators, pressure
regulators, turbine wheels, control panels, transformers,
monitoring systems and more.
Q3, Can you do EPC for a hydroelectric power plant?
Yes, we can provide TURN-KEY and EPC services including
measurement, design, manufacturing, construction, manufacturing,
commissioning, inspection, maintenance runner replacement and
refurbishment/upgrade/improvement/repair/refurbishment of
turbines/generators including bearings, seals For parts and key
parts, we will send technicians and workers to install equipment.
Q4,Is your company a trading company or a manufacturer?
We are a manufacturer of hydro turbine generators and started to
promote the international market in 2013. Our factory is located in
Sichuan, where China's water conservancy and hydropower is most
developed. Welcome to visit our factory in China.
Q5, What is an acceptable MOQ?
For this product, our acceptable MOQ is 1 set.
Q6,How long is the delivery time?
Delivery times range from 15 days to 6 months depending on the
model you are purchasing.
Q7,Does the runner of Francis turbine produce negative pressure
during operation? If the negative pressure will be generated, where
will the negative pressure be generated, and how much range should
we choose the measuring instrument?
When the turbine is in an operating state of no-load, low head,
small load, high head, and overload and large flow, it will cause
the dynamic load caused by pressure pulsation and hydraulic
disturbance.
Since the Francis turbine is a fixed-blade hydraulic machine, when
the turbine runs away from the optimal working condition, a large
vacuum is generated in the area near the axis of the draft tube due
to the rotating circumferential velocity of the runner outlet water
flow.
The pulsation produces instantaneous negative pressure, the vacuum
is not high, and it is not suitable for measurement due to its
generation in the casing. Vibration, audio and other alternative
measuring methods can be considered.
Due to the uneven gap between the rotating part and the fixed part
of the turbine, the center of the wheel is deviated from the center
of the unit. The gap between the fixed and rotating labyrinth rings
of the wheel is constantly changing with the rotation of the wheel,
and the water pressure in the gap changes accordingly.
When the flow of water flowing into the runner loses its
axisymmetricity, an unbalanced lateral force occurs and pressure
pulsations also occur.
Q8,Does your company have its own independent official website?
Of course, and we can see more information about our company and
products on our official website.
