大型混凝土搅拌机磨合期如何减少负荷?

作者:http://www.zkzsljbc.com 时间:2021-08-26

大型混凝土搅拌机操作职员应接收生产厂家的培训、导,对机器的构造、性能有充足的懂得,并获得必定的操作及维护经验方可操作机器。生产厂家供给的产品使用说明书,是操作者操作装备的必备材料,在操作机器前,必定要先浏览使用说明书,按说明书的请求进行操作、保养。
The operators of large concrete mixer shall receive training and guidance from the manufacturer, have sufficient knowledge of the structure and performance of the machine, and obtain certain operation and maintenance experience before operating the machine. The product operation manual provided by the manufacturer is the necessary material for the operator to operate the equipment. Before operating the machine, you must browse the operation manual and operate and maintain according to the requirements of the manual.
注意大型混凝土搅拌机磨合期的工作负荷,磨合期内的工作负荷一般不要超过额定工作负荷的80%,并要部署合适的工作量,防止机器长时光持续作业所引起的过热现象的产生。注意经常察看各仪表唆使,呈现异常,应及时停车予以消除,在原因未找到,故障未消除前,应结束作业。
Pay attention to the working load of large concrete mixer during the running in period. Generally, the working load during the running in period shall not exceed 80% of the rated working load, and appropriate workload shall be deployed to prevent overheating caused by long-term continuous operation of the machine. Pay attention to regularly check the instigation of each instrument. In case of abnormality, stop the machine in time to eliminate it. The operation shall be ended before the cause is not found and the fault is not eliminated.

还有注意经常检讨润滑油、液压油、冷却液、制动液以及燃油油(水)位和品德,并注意检讨整机的密封性。检查中发明油水缺乏过多,应剖析原因。同时,应强化各润滑点的润滑,建议在磨合期内,每班都要对润滑点加注润滑脂(特别请求除外)。操作员应坚持对大型混凝土搅拌机每一设备进行清洁,及时调剂、紧固松动的零部件,以防因松动而加剧零部件的磨损或导致零部件丧失。磨合期结束后,应对机器进行强迫颐养,做好检讨和调剂工作,同时注意油液的调换。
In addition, pay attention to regularly review the level and morality of lubricating oil, hydraulic oil, coolant, brake fluid and fuel oil (water), and pay attention to the tightness of the whole machine. In the inspection, it is found that there is too much oil and water, and the reason should be analyzed. At the same time, the lubrication of each lubricating point shall be strengthened. It is recommended that the lubricating points be filled with grease every shift during the running in period (except for special requirements). The operator shall insist on cleaning each equipment of the large concrete mixer, timely adjust and fasten the loose parts, so as to prevent the wear of parts or loss of parts due to looseness. After the running in period, the machine shall be forced to take care of, review and adjust, and pay attention to the exchange of oil.
大型混凝土搅拌机生产混凝土的原料一般分为水泥、粗细骨料、水、外加剂等材料,材料的质量好坏就直接影响出产的混凝土的质量好坏,因此在材料的选择上不可大意。对大型混凝土搅拌机内的水泥应选择当地大型厂商出产的正规产品,保质保量,并检测好混凝土凝结时间、安定性、强度等重要指标。粗细骨料要选用优质砂石,砂石粒径越大,混凝土强度就越高,但价格自然也越高。在保住强度的情况下,可降低水泥和外加剂的用量。
The raw materials for the production of concrete by large-scale concrete mixer are generally divided into cement, coarse and fine aggregate, water, admixtures and other materials. The quality of materials directly affects the quality of concrete produced. Therefore, we should not be careless in the selection of materials. For the cement in the large concrete mixer, the regular products produced by large local manufacturers shall be selected, the quality and quantity shall be guaranteed, and the important indexes such as concrete setting time, stability and strength shall be tested. High quality sand and gravel shall be selected for coarse and fine aggregates. The larger the particle size of sand and gravel, the higher the concrete strength, but the higher the price naturally. Under the condition of maintaining the strength, the dosage of cement and admixture can be reduced.
拌制混凝土用的水也不可小看,虽然一般都直接使用自来水,但也应检验水成分,因各地水质不同,有些地方的自来水水质不宜作为拌制混凝土使用,需特别注意。后是外加剂,外加剂的种类有磨细粉煤灰、磨细矿渣、磨细天沸石和硅灰及其复合物。为保证大型混凝土搅拌机外加剂的有效含量,应加强对液体外加剂浓度的检验。
The water used for concrete mixing should not be underestimated. Although tap water is generally used directly, the water composition should also be tested. Due to different water quality in different places, the tap water quality in some places should not be used for concrete mixing, and special attention should be paid. Then there are admixtures. The types of admixtures include ground fly ash, ground slag, ground zeolite, silica fume and their composites. In order to ensure the effective content of admixture in large concrete mixer, the inspection of liquid admixture concentration should be strengthened.
