For many years , the drying furnace has been adopted with sealed structure and electrical heated , dial instruments are used to control the temperature of the drying furnace and to keep it invariable . parameter setting is inputted by manual method , heating time is completely controlled by operators ’ experiences or their moods , meanwhile , its control function is singular , not only having no automatic heating time and insulating monitoring , having no drying process monitoring , but also having no function of automatic recording and report printing , the workers ’ labor intensity is bigger . thus two abnormal situations are always come forth , one is the insulating performance and intensity of works cannot be guaranteed reliably , it perhaps need to be dried repeatedly , the other is always to extend the drying time in order to ensure the drying quality 多年来干燥炉一直采用闷罐式结构和电加热方式,温度控制采用指针式温度控制仪表来实现炉温的恒定,其参数设定由人工输入,时间控制则完全凭操作者的经验、情绪来掌握,其控制功能单一,没有时间控制、绝缘自动监测功能,也没有干燥过程监视功能,更没有多要素记忆、打印存档功能,工人的劳动强度较大,所以就经常出现两种异常结果:一是工件的绝缘性能和强度得不到可靠保证,需要反复干燥;另一种是为保证干燥质量,往往要延长干燥时间。
In this kind of system , one or two solenoid valves are fixed in the high - pressure pipe to control the action of the injection pump and the injection nozzle . in such situation , the quantity of injection , the timing of injection and the rate of injection can be flexibly and controlled , which will contribute greatly to the performance of both power and fuel economy . thus the timing control method has become the tendency of the electrically controlled diesel engine 在这类系统中，高压油路中利用一个或两个高速电磁阀的启闭来控制喷油泵和喷油器的喷油过程，可实现对喷油量、喷油定时和喷油速率的柔性控制和一体控制，这对提高柴油机的动力性和经济性无疑将会起到重大的作用，时间控制方式也因此而成为柴油机电子控制的发展方向。
This new scheme can detect the malfunction of database system and superintend the operation system connecting to standby database when the host database is paralyzed . the entire switch time can be controlled in several minutes . after the host database restoring , all operations on standby database should be recurred on host database 自动切换功能可以在主用数据库发生异常时自动切换到备用数据库继续工作,使数据库故障对设备乃至网络的影响时间控制在几分钟以内,主用数据库恢复以后,在备用数据库上进行的操作应该能恢复到主用数据库上。
The printing speed of dpc 1255 is 12 . 5 a4 per minute for color printing , and the speed of black - and - white printing reaches 50 a4 per minute . while ensuring high - quality output , it also obviously accelerates the printing speed . this change has not only reduced printing costs , but also enabled flexibility in scheduling Dpc 1255的彩色打印速度为每分钟a4 - 12 . 5页，黑白打印速度更达到每分钟a4 - 50页，在保证高质量输出的同时，速度上的提升十分显著，不但降低了成本，更可实现时间控制上的灵活性。
