| The highly active energy
conservation system of fan |
[model
meaning]
 |
[outline]
The fan is one kind of equipment used quite largely at present in
every walk of life, for example: the machinery, the metallurgy, the
petrochemical, the electric power, the building materials, the guesthouse,
the housing and so on. While, the installed capacity of the fan is
very big, therefore the energy conservation and consumes falling of
fan has quite large prospect. Besides, this system also may reduce
the noise of fan, especially in the guesthouse and the housing.
[Saving principle]
The frequency conversion energy conservation of fan is realized
through the adjusting of rotational speed. The fan is one kind of
short load reducing rotational speed. The consumed power by the fan
is proportional with the product of wind pressure and wind rate. Along
with the reducing of rotational speed, the load rotational speed of
fan reduces pro rata with the square of rotational speed, and the
power reduces by the cubic ratio with the rotational speed. Obviously
that using the frequency conversion velocity modulation method to
energy conservation has the best effect.
[Function characteristics and technical
characteristics]
The wind pressure characteristic of fan: Under
the condition that the rotational speed of fan is unchanged, the relational
curve between wind pressure and wind rate is called the wind pressure
characteristic, which is quite with the delivery lift characteristic
of water pump.
The wind resistance characteristic of fan:under
the condition that the jaw opening of air door is unchanged, the relational
curve between wind pressure and wind rate is called the wind resistance
characteristic, which is quite with the pipe choking characteristic
of water pump.
[the installation and debugging of control
system]
Our company has measuring appliance engineers who have been engaged
in the chemical automation for many years. They will provide the design,
the configuration, the installation and the debugging of the field
measuring appliance (transmitting instrument, regulator valve and
so on) and the control system (DCS, PLC, ESD and so on) for you.
The setup work of equipments is constructed strictly according to
the plan, which conforms to the requests of ‘Electric device Installation
work Construction And Approval Standard’. |
