1 、安装时应注意阀体上箭头应与介质流向一致。不可装在有直接滴水或溅水的地方。沥青保温泵应垂直向上安装。 1, when installation should pay attention to the body should be consistent with the arrow to the flow direction of medium. Do not put in a direct drip or splash water place. Asphalt insulation pump should be vertical Upward installation. 2 、 RCB 沥青保温泵应保证在电源电压为额定电压的 15%-10% 波动范围内正常工作。 2, RCB asphalt insulation pump shall ensure that the power supply voltage for 15% of the rated voltage - 10% fluctuation range normal work. 3 、沥青保温泵安装后，管道中不得有反向压差。并需通电数次，使之适温后方可正式投入使用。 3, asphalt insulation pump after installation, in the pipe can not have reverse pressure difference. And to power on several times, the optimum temperature rear can formally put into use.

4 、沥青保温泵安装前应彻底清洗管道。通入的介质应无杂质。阀前装过滤器。 4, asphalt insulation pump before the installation, should be thoroughly clean pipeline. Pass into the media should have no impurity. Valve front loading filter. 5 、当发生故障或清洗时，为保证系统继续运行，应安装旁路装置。 5, when malfunction or cleaning, to ensure the system continues to run, should install bypass device. RCB 沥青保温泵对工件时效前应进行工艺分析 RCB asphalt insulation pump on the aging process analysis should be done before 振动时效的效果取决于振动时效的工艺的选择。冶金蝶阀体，是由铸造而成的结构件，沥青保温泵形状复杂，刚性相对大，凸凹面多，壁厚不均，残余应力大且分布繁杂。以前采用自然时效的工艺中存在很多的缺点，某公司自 2005 年开始采用振动时效工艺以来，在产品的质量和生产效率方面取得了很大的进步。多年的生产实践经验表明 : 由于振动时效的工艺比较复杂，必须对箱体类零件进行振前的工艺分析，设计优化振动参数以提高振动时效的效果。 Vibration aging effect depends on the vibration aging technology choice. Metallurgical butterfly valve body, is by casting a structure, asphalt insulation pump complex shape and rigid relatively large, uneven surface, wall thickness uneven, residual stress distribution of large and complex. The natural aging process before there are many shortcomings, a company since 2005 by vibration aging technology since, in the quality of products and the production efficiency has made great progress. Years of production practice experience shows that: because of vibration aging technology is more complex, must in the parts before for vibration analysis of the technology of design optimization vibration parameters in order to improve the effect of vibration aging. 按照振动失效的工艺规范，沥青保温泵对工件时效前应进行工艺分析，以达到节约电能和工作时间的目的。首先，应根据工件的材质、结构、毛坯制造的工艺形式和过程，分析箱体的残余应力场的分布，尺寸精度要求，以及工作载荷，可能的失效原因等因素进行分析，然后再决定实施振动时效的工艺路线及时效重点部位。 According to the vibration failure process standard, asphalt insulation pump on the aging process analysis should be done before, so as to save electricity and working time of purpose. First of all, should be based on the workpiece material, structure, blank manufacturing process form and process, and analyses the distribution of the residual stress, dimension accuracy requirement, and the working load, may be the reason of failure factors analysis, and then decided to implement vibration aging technology route and aging key parts. Briefly RCB asphalt insulation pump use standard 简述 RCB 沥青保温泵的使用规范 我们在使用沥青保温泵的时候一定要制定严格的技术维护保养规范，燃油滤清器工作 100 小时，油箱工作 500 小时各清洗一次，若发现滤芯破损失效应及时更换，不得将其拆除而采用直流式供油。偶件在正常工作条件下工作 500 小时应拆卸检查一次。在拆卸检查沥青保温泵时要保证场所、手、工具和清洗油清洁，以免偶件受污染。在拆卸操作时不得乱敲乱打，在清洗时不要乱堆乱放，不应和其它非偶件在一起盆洗，以免碰伤、擦伤。在装配时不得随意改变装配位置而达到某些不符合机器工作要求的目的。在装出油阀紧座和油嘴紧帽时，应按规定力矩拧紧，以保证装配后的喷油器和喷油泵技术状态的良好。弄懂偶件的结构特性和工作原理，加强和提高对偶件的维护保养、操作使用，做到无故障时不随意调整，维护使用时不随意拆卸，维修检查时不乱敲乱打，清洗保养时不乱擦乱碰，装配调整时不乱改乱拧，一切按沥青保温泵规范技术要求进行，以达到延长沥青保温泵使用寿命的目的 We in the use of asphalt insulation pump must be formulated strict technology maintenance standard, fuel filter work 100 hours, the fuel tank work 500 hours each cleaning once, if discover filter broken loss effect change in time, and shall not dismantle the the once-through fuel supply. Couple under normal working conditions work 500 hours should remove a second look. When removing check asphalt insulation when the pump to ensure the place, hand, tools and cleaning oil clean, in order to avoid couple contaminated. When removing operation shall not knocking wild shot, when clean don't heap shoved, not have other non couple together wash basin, in order to avoid bruising, bruises. In the assembly can not change assembly position and achieve some does not comply with the machine work requirements for purposes. In pretend oil valve tight seat and nozzle cap nut, should press formulary moment tightening, to ensure that the assembly after the fuel injector and fuel injection pump technology state of good. Understand couple structure characteristics and working principle, strengthen and improve dual a maintenance, operation, do trouble-free not adjust, maintenance use involuntary removal, maintenance inspection without knocking wild shot, cleaning and maintenance without disorderly wipe disorderly touch, assembly adjustment not disorderly change disorderly screw, all according to the asphalt insulation pump standard technical requirements, in order to prolong the service life of asphalt insulation pump purpose
