Top.Convenient for by pipeline connection outside gas collector, further include the fan 10 being set to below cooler.For setting
Standby internal heat dissipating.
Head system is the prior art, and details are not described herein.
The application permanent-magnetic variable frequency screw machine uses the magneto of rare earth permanent-magnetic material production, and rotor realizes rare earth forever
Magnetization, no slippage, no excitation, rotor are few without fundamental wave iron, copper loss and calorific value, reduce the damage of stator current and stator resistance
Consumption, efficiency ratio improve 5%~12% with capacity asynchronous motor.Host header is driven using motor direct-connection type, it is compact-sized,
Shape is exquisite beautiful.
Working principle is summarized as follows:
The permanent-magnetic variable frequency screw machine money kind of drive, using motor as power source, direct connection drives head to be driven in a manner of 1:1, leads to
Frequency converter is crossed to be adjusted the speed.By taking 37KW is calculated as an example:
Speed is all 3660rpm, pressure at expulsion 0.8MPa, capacity Qo=5.84m3/min；
A. the complete machine input power of permanent-magnet synchronous frequency conversion type is measured as Pi=40.36kW, then the input specific power of complete machine
Are as follows: qi=Pi/Qo=40.36/5.84=6.91；
B. the input power of common asynchronous power frequency type is measured as Pi=43.64kW, the input specific power of complete machine are as follows:
Qi=Pi/Qo=43.64/5.84=7.47Kg；
When the revolving speed of logical asynchronous machine and load are less than the rated point of design, the efficiency of motor is decreased obviously, and difference
Bigger its efficiency decline is more obvious.
When common asynchronous moter operates in lower frequency, it may appear that the problem of output torque deficiency, so that frequency converter goes out
Existing " motor torque overload " and the failure of chaser.Common asynchronous moter there is also rotary speed unstabilization when running under lower frequency
Phenomena such as fixed, vibrating noise increases, calorific value increases.
Present new control mode be using magneto+dedicated variable frequency drives control mode, have it is high-efficient and
Always it is able to maintain the fast response time of permanent torque operation under very high horizontal, any revolving speed, stabilization of speed, rotation speed change
(be within 50ms from 0 to acceleration time of rated speed, and dash current be not present), the advantages such as low noise.
Energy-saving effect comparison:
Same two kinds of types for being 37kW by front rated power, when load factor only has 60%, common air inlet restriction control
The input power of the power frequency type of system is 38.2kW, and the shaft power of permanent-magnetic variable-frequency type is 23.6kW, and power saving rate reaches
37.5%.If fruit is calculated for 4000 hours by annual work, the common annual electricity charge expense of asynchronous power frequency type is 10.72 ten thousand yuan,
And if using permanent-magnet synchronous frequency conversion type instead, annual electricity cost if is 6.58 ten thousand yuan, and the electricity charge saved every year are
4.14 ten thousand yuan.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
