supply area,water pollution,infrastructure investment,but the main drawback
is that water can not be kept constant,causing part of the equipment can not
work normally.Variable frequency speed control technology is a new mature AC
motor stepless speed regulating technology,its unique excellent control
performance is widely applied to the speed control field,especially in water
supply industry.Due to the safety in production and the water quality of
special needs,for constant pressure water supply with the stringent
requirements,so the frequency control technology has been more in-depth
application.Constant pressure water supply ways to advanced technology,
constant pressure,convenient operation,reliable operation,energy saving,
high degree of automation,in pump station water supply can perform the
