01 Attributes Of permanent CZPT Variable Frequency Air CZPT

It is a unique new design and style, which combines the permanent magnet motor and the pace management frequency converter. It couples with the higher quality air stop, which exhibits the superior screw compressor technology.

1.CZPT-lower temperature increase layout, which permits the compressor operating at extremely-minimal frequency for a prolonged time.

two.Closed-loop vector manage technique for more rapidly control and much more precise pace management.

three.The compressor unit can nonetheless work efficiently when the frequency is diminished by more than 50%.

four.The pressure is stable and the strain fluctuation is correctly managed within .1 bar.

five.The figure displays a comparison of a number of beginning techniques. It can be witnessed that the frequency converter is slowly accelerated to commence, the starting up is far more stable, and the current peak is fully averted.

02 Air Finish

Far more secure, no mechanical transmission failure: high-efficiency everlasting magnet synchronous motor and screw male rotor undertake embedded-integrated shaft immediate connection structure, no gear transmission, completely remove equipment pitting or broken teeth Two unbiased everlasting magnet motors are built-in directly travel two air finishes, no coupling failures.

Much more energy efficient, the air finish is constantly operating at energy-conserving velocity.

More efficient and successful permanent magnet motor + no transmission effectiveness loss.

Much more comfy, low operating noise, removing a few resources of sounds: no-click on bearing sound, no equipment meshing noise, no coupling travel sound.

More compact: The long lasting magnet motor is modest in measurement and the built-in structure saves room.

Beneath the established frequency conversion force, the device will routinely change to preserve the output stress inside ± .1 bar, lowering needless waste (the electricity intake will increase by seven% for each 1 bar of force improve)

.three Positive aspects of Long lasting CZPT CZPT In comparison to CZPT Asynchronous CZPT

Substantial effectiveness: Gets rid of excitation method losses and improves efficiency.

It is even now effective beneath low load situations: the vitality effectiveness of a long term magnet motor is much more than 9% higher than that of a conventional asynchronous motor at entire load operation, and its power efficiency continues to be unchanged as the speed decreases.

Huge overdrive torque: The ratio of the highest beginning torque of the long term magnet synchronous motor to the rated torque can be a lot more than three times, while the general asynchronous motor is only one.six instances.

The management is much more secure: the corresponding time of the everlasting magnet motor is <50ms, and the gas production can be adjusted in a large range in an instant, so that the gas pressure is truly stable.
