This paper provides a kind of roller maintain machine. It introduced the structure and the working principle of the roller disassembly and assembly machine. According to the work requirements, selected the PLC Toshiba's F1-20MR,to realize the switching sequence control function. Analyzed machine's work flow, Designed the PLC control program. Point out the advantage that using PLC replaced the original relay logic control systems: flexible application and good generality; high reliability and environmental adaptability; the program is simple to grasp easy. © (2012) Trans Tech Publications, Switzerland.

This paper provides a method of supply constant pressure air for air conditioning system. It analysis the energy consumption betwwen the damper adjuste air flow with variable frequency speed regulation adjuste air flow. The paper Introduce the Energy conservation principle of the frequency control blower. The supplying air Pipeline subject to a uniform force, the equipments mechanical properties was improved. The results show that Uses the frequency conversion velocity modulation to carry on supply constant pressure air, obviously reduces the energy consumption. The electrical motor starting characteristic is improved, realizes the electrical motor soft start. © (2012) Trans Tech Publications. Source
