Control and Its Application
AC motor speed control primarily on the basis of different
load torque requirements process or through AC inverter
regulate motor speed, spindle motor to change the
output characteristics. Fans such as pumps used in
fluid load will enable fluid flow and pressure according
to actual needs constant voltage or constant flow
automatically adjust. Than it used valves, adjust
expenditure orifice flow or pressure energy savings,
while extending equipment life and solve the area,
equipment launched frequent, serious impact of current
and pressure, a large quantity of equipment maintenance,
and other issues.
According to principles of fluid mechanics, water
pumps and the flow of motor speed is proportional
to the pressure and the motor speed is proportional
to the square, a VVVF fan pumps, energy saving effects
than the use of pressure or flow control valve of
energy-saving method can be 40 percent ~ 50 percent,
water-saving 7 percent. Conventional pumps most of
the time running at rated load, in particular water
plant and residential living water supply, according
to its design maximum load water pump selection, and
24 h of water daily load great changes in the evening
less water use Frequency constant pressure water supply
equipment, according to the size of water changes,
the automatic adjustment of pump speed, while ensuring
constant pressure on the water supply, not only can
save a lot of energy, extend equipment life, and solve
the water pollution problem in the second, is a very
ideal high-tech energy-saving products.
This product adaptation of generic three-phase asynchronous
motors, a new type of power devices, digital control.
Application:
1¡£ Living areas, high buildings, such as water supply
and hot water heating system.
2¡£The cycle of various types of central air conditioning
pumps, cooling water supply system.
3¡£ deep-well pump (deep-well pump, submersible pumps)
Water Supply System.
4¡£ sewage treatment plants, water supply drainage
station automation systems.
5¡£ The petrochemical industry load the fluid flow
and pressure control systems.
6¡£ Various Blower, Fan, ventilation machines, air-conditioning
fans, cooling tower fan and other air volume control
system.
7¡£The transit point for oil, lose, lose-doped, water
supply systems. 8¡£Industrial and mining enterprises
in the production and living water.
Automatic Fault Protection: overload, short-circuit
protection, over-voltage protection, lack of protection,
under voltage protection, thermal protection, over-current
protection, as well as over-voltage, overload, less
transient voltage electricity restored to start.
Frequency control cabinet selection:
Users with a high degree of water quantity and water
pumps or Taiwan and several models, the installation
location, Locker body size, and other technical requirements,
our company can be personalized customized.
Choice the pump power: 15-350 KW |
