但是由于其周围温度环境(辐射、热传导及对流状况等)与电机内部的发热规律不一致,所以不能对电动机进行有效的保护。
But because of the temperature environment (radiation, heat conduction and convection) and the internal heat of the motor is not consistent, so we can not effectively protect the motor.
他认为,由于生产电动汽车需要新零件和新技术,所以在这方面,一个小型新公司可能比传统汽车制造商更具竞争力。
Since producing electric cars requires new parts and technologies, he believed a small entrant could better compete with these new vehicles than traditional automakers.
但是,他们告诉我们,以及ecu的故障,电动车窗和中央门锁,可一定的不确定因素,所以做了彻底检查所有的电器。
But, they tell us that, as well as an ECU glitch, the electric Windows and central locking can be iffy, so do a thorough check of all the electrics.
但传统的一体化结构产品也有很多不完善的地方,所以产生了智能电动执行器。
However, the integration of traditional structured products, there are many imperfections, it had intelligent electric actuator.
所以,虽然现在电动调节阀应用范围越来越广,但是在化工领域,气动调节阀还是占据著绝对的优势。
So, while the scope of application of electric control valve more and more widely, but in the chemical industry, pneumatic control valve or occupy an absolute advantage.
电动执行机构主要优点是驱动源方便,但价格高,可靠性、防水防爆不如气动执行机构,所以应优先选用气动式。
The main advantage of electric actuators is the driving source convenient, but high price, reliability, water proof as pneumatic actuator, it should be preferred pneumatic.
