heat requirement
1.1. At first, through ignitron work principle, arc discharge characteristic and heat distribution, ignitor’s performance requirement is got, namely: ignitor can’t be soaked by mercury;
2.After processed by this heat treatment technology,products could meet the each requirement of API 5D and achieve the middle and upper level of S135 steel type.
3.Heat Mirror insulating glass may use spectral selective film at various visible light transmittance, to satisfy different design requirement of natural lighting and solar heat rejection.
4.Our company is specialized and experienced in making shoe machinery：universal oil sole presser, Walled sole presser, Hydraulic walled sole presser, heat setter, chill master, cutting equipment. we will provide in mass production to meet the requirement of our customers.
5.The tests results showed that the ambient tensile properties and the tensile and stress rupture properties at 538 ℃ of the steel ZG15Cr1MoA (C≤0.22%, Cr 0.95%～1.65%, Mo 0.43%～0.67%) cylinder casting for st eam turbine heat treated with normalized at 950 ℃ and tempered at 680 ℃ met the needs of standard requirement.
6.The heat treatment technology of the whole quenching and self backfire of the bridge crane’s wheel is probed into,which takes the place of surface quenching technology and insures the requirement of the wheel’s quality,greatly improving the wheel’s life span.
7.But with the shortcoming such as the poorreliability and disability of controlling laser output power, the old Single BoardComputer (SBC) control system can fit to the requirement of heat treatmenttechnology.
8.Based on a constructing project, a water source heat pump system in a large-scale residential quarter and in view of the characteristic of the system with numerous equipments, complex control, decentralize distribution and the control requirement is discussed. Reasonable scheme of DCS composed with DDC by comparing typical control system styles are given and the optimize control method of single machine, multi-machines and entire system are presented.
9.From the actual conditions of the cold regions,it is discussed the requirement of house windows from building energy efficiency standard.From the two aspects of heat gain and heat loss in buildings,the energy efficiency principles of windows are analyzed and the development trend of the technology of energy efficiency windows is also given.
10.Beased on a constructing project,a water source heat pump system in a large-scale quarters,and in view of the characteristic of the system: numerous equipments,complex control,decentralize distribution,writer discusses the control requirement concretely,gives reasonable scheme of DCS composed with DDC by comparing typical control system styles,and presents the optimize control method of single machine,multi machines and entire system.
