对设备采取什么样的修理体制进行修理,目前仍众说不一,各抒已见,但都认为预防修理好于事后维修。现在,无论是美国的“PM”日本的“TPM”,或是苏联的“ΠΠP”等,均属于预防修理范畴,就连化工企业里执行的计划检修制也属此范畴。 所谓计划检修就是有目的、有计划地对生产设备进行检查与修理。通过检查(点检、定检)可以得到设备运行状况的第一手技术资料,以便指导下次检修;通过修理可以使设备技术性能得到恢复,为企业生产经营服务。 化学工业随着科学技术飞跃发展,涌现出很多新技术、新工艺、新产品,其技术条件对生产设备要求越来越苛刻,对环境保护的要求也越来越严格,这样就形成化学工业与其他工业相比较,其特殊性也就越来越明显,概括说有如下六个方面的特殊性: 1.低温、高温、高压、易燃易爆、强腐蚀。化工生产设备普遍承受这些工艺条件,而
What kind of repair system is used to repair the equipment is still being talked about in various ways. All of them have seen it, but they all think that preventive repair is better than repairing afterwards. Now, whether it is the “PM” Japan’s “TPM” in the United States, or the “ΠΠP” in the Soviet Union, it belongs to the category of preventive repair, and even the planned maintenance system implemented by chemical companies is also in this category. The so-called planned maintenance is the purposeful and planned inspection and repair of production equipment. Through inspection (spot inspection, inspection), first-hand technical data of equipment operation status can be obtained to guide the next inspection and repair; equipment repair can restore the technical performance of the equipment and provide production and operation services for the enterprise. With the rapid development of science and technology, the chemical industry has emerged a lot of new technologies, new processes, and new products. Its technical conditions have become increasingly demanding for production equipment, and the requirements for environmental protection have become more and more stringent, thus forming a chemical industry. Compared with other industries, its particularity is more and more obvious. In summary, there are six special features: 1. Low temperature, high temperature, high pressure, flammable, explosive and strong corrosion. Chemical production equipment generally withstands these process conditions.
