First difference between permanent magnet and power frequency inverter screw compressor screw air compressor
Energy efficiency and high power frequency screw air compressor once the deviation from the rated condition, the efficiency will have a range of decline, energy saving air compressor will become not energy. Mountains permanent magnetic frequency conversion technology can according to the changes in the volume of motor speed control, and then adjust the amount of exhaust, the any gas compressor can maintain high efficiency. So compared with a frequency of screw air compressor, when system for volume fluctuations, permanent magnetic screw air compressor has advantages in energy saving and fluctuation is bigger, the energy-saving effect is more obvious, the comprehensive energy saving can be as much as 50%.

First permanent magnet inverter screw machine 183520KW (real power)
Above the 37KW screw air compressor, for example, according to the experimental test results, the average running time of 8000 hours per year:
First permanent magnet frequency than ordinary screw air compressor screw air compressor sales: 281200-183520=97680KW.
The difference between first permanent magnet screw air compressor and inverter plug screw air compressor
Ordinary screw air compressor can adjust the speed of the motor by the way of the external frequency converter, so as to adjust the exhaust quantity, so that the gas production and gas consumption can be adjusted to achieve the effect of energy saving. But the ordinary screw air compressor used by the motor are rated speed, rated power and rated efficiency, the external frequency converter forced air compressor motor deviation from the rated speed. And ordinary motor once the deviation from the rated speed, the efficiency will be greatly reduced, the more the more efficient the more efficient. The permanent magnet frequency conversion motor of permanent magnet frequency conversion motor can be maintained at any speed, and can maintain a high motor efficiency, so the energy saving effect is much better than the ordinary screw air compressor.
In addition, on inverter plug-in ordinary screw air compressor with a tuning range of 40-100%. That is to say when the deviate by more than 60% of the cases from, on inverter plug-in will not regulating motor speed, and mountains of permanent magnetic screw air compressor adjustment range for 15-100%, that mountains permanent magnetic screw air compressor from 85 per cent of the condition can be normally work.

First permanent magnet screw air compressor technological advantages compared to ordinary permanent magnet inverter screw air compressor
A high efficiency of the permanent magnetic frequency conversion screw air compressor need to achieve the best in the following three aspects:
One is to have a high efficiency of the screw host
Two is to have a high efficiency of permanent magnet synchronous motor
Three is to have a class of permanent magnet frequency conversion control technology.
First permanent magnet screw air compressor in these three aspects has obvious technical advantage.
Pioneer permanent magnet inverter screw compressor than ordinary permanent magnetic screw air compressor in the three aspects of screw extruder efficiency, the efficiency of the motor and control technology has obvious advantages.
First permanent magnet screw air compressor 12 technical advantage
1 screw engine efficiency advantages
The general manager of the company, the national "thousand person plan" expert Dr. Tang Yan is one of the world's most famous expert of screw compressor. He invented the T, Y-, a type line for the United States, China and more than the use of famous companies. Dr. Tang Yan mountains shares with design of the screw host allows the company of each screw compressor are up to the national level 1. Screw host high efficiency is the pioneer permanent magnetic screw air compressor with respect to ordinary permanent magnetic screw air compressor is more efficient.
One of the advantages of 2 high efficiency permanent magnet synchronous motor
Mountains of permanent magnet synchronous motor (PMSM) because the use of special rare earth permanent magnet materials, with more high speed, wide adjustment range and higher efficiency.
3 high efficiency permanent magnet synchronous motor two
Mountains of permanent magnet synchronous motor high efficiency reflected in the motor itself less heat, so the mountains high efficiency permanent magnet synchronous motor adopts fully enclosed structure design, to completely solve the intrusion of dust and impurities. Ordinary permanent magnet synchronous motor (PMSM) because of the low efficiency, calorific value high, structural design need to have the ventilation openings. This structure makes the air containing iron dust into the motor, accumulate over a long period can lead to the failure of the motor coil. Therefore Kaishan product eliminates a huge hidden trouble, better reliability, higher efficiency, longer life, lower noise (mountains 37KW permanent magnetic screw air compressor running noise low to 65 dB).

4 high efficiency permanent magnetic synchronous motor advantage three
Mountains of permanent synchronous motor heat resistant temperature up to 180 DEG C, compared to the domestic products of the same kind of 120 DEG C increased by 50%, guarantee in any case will not loss of excitation.
5 high efficiency permanent magnetic synchronous motor advantage four
Pioneer permanent magnet synchronous motor rotor for the rare earth permanent magnet, so no slip, no electrical excitation, no rotor fundamental iron loss, copper loss. No need to learn motor excitation current from the power grid, power factor close to 1 speed and high precision, the speed error 1/30000, great
