The power saving control system of air compressor manufacturer has accurate pressure control ability. The air pressure output of the compressor is matched with the air volume required by the user's air system. The screw air compressor manufacturer controls the output air volume of the compressor to change with the change of motor speed. Because the precision of controlling the speed of the motor is improved, it can keep the system pressure of the pipe network unchanged.

它的起动加速时间可以调整，从而减少起动时对压缩机的电器部件和机械部件所造成的冲击，增强系统的可靠性，使压缩机的使用寿命延长。此外，控制能够减少机组起动时电流波动，这一波动电流会影响电网和其它设备的用电，节 电 器能够有用的将起动电流的峰值减少到低程度。

Its starting acceleration time can be adjusted to reduce the impact on the electrical and mechanical parts of the compressor, enhance the reliability of the system and prolong the service life of the compressor. In addition, the control can reduce the current fluctuation when the unit starts, which will affect the power consumption of the grid and other equipment. The energy saver can effectively reduce the peak value of the starting current to a low level.

很多见过螺杆空压机几面的创业先锋拉起一票人马就敢开工生产。对于所需生产技术，大多数企业表示无压力，所产螺杆空压机确实可以运行起来，价 格还不贵。但要说型线改进、能效好，这在国产身上比较少见。

Many pioneers who have seen screw air compressors dare to start production by pulling up one vote of people. For the required production technology, most enterprises say that there is no pressure, the screw air compressor can really run, the price is not expensive. However, it is rare for domestic brands to have improved product lines and good energy efficiency.

形成的局面是，在能生产勉强达标产品的基础上，对于创新研发不屑一顾，认为以自己现有的技术足够了，没必要再花精力和资金去完善和创新。这个技术水平所产设备和形成的观念放在前几年确实可行，但在市场环境发生变化之后，要维持温饱都会显得困难。

The situation is that, on the basis of being able to produce barely up to standard products, they are dismissive of innovation and R & D. they think that their existing technology is enough and there is no need to spend energy and money on improvement and innovation. It is true that the equipment and concepts developed at this technical level are feasible in the past few years, but it will be difficult to maintain food and clothing after the market environment changes.

转不转都是个问题，不转眼看就活不成了，但转型，花钱就能研究出成果吗?研究出来的能被市场认可吗?被行业领头羊挤兑，被“拿来主义者”模仿，认真搞研究真的是出路吗?

It's a question whether we can turn around or not. If we don't turn around, we won't be able to survive. But can we spend money on the transformation to produce results? Can the research be recognized by the market? Is it really the way out to be run by the industry leader, imitated by the "take it" and seriously engaged in research?
