在现代化连续生产过程中,其设备管道、阀门、法兰及各种静密点的泄漏是经常发生的现象,但没有科学的堵漏方法,只能采取局部或全线停车进行修理。这不仅造成原材料、能源的浪费,还会由于易燃、易爆有害物质的外溢,造成环境污染,危及设备和人身的安全。国营黎明机械公司与有关部门共同研制成功不停车、带压、带温、强注式堵漏技术,已在辽化、天化等现场应用,取得了良好效果。辽宁省国防科工办受航空工业部的委托对这项成果进行了技术鉴定。鉴定委员会一致认为:这项技术系国内首创,填补了现代堵漏技术的空白。它的特点是不停车、带压、带温条件下进行作业。这一新技术具有堵漏迅速,工艺简单,操作方便,密封性好,不停车,减少能源浪费,消除环境污染,经济效益显著等优点。此外,在堵漏作业前,不需要对泄漏部位作任何处理,密封剂也不粘附基体金属,因而不影响以后的拆卸和维修。
In the process of continuous production, leakage of equipment pipes, valves, flanges and various static points is a common phenomenon. However, there is no scientific method of plugging, and only partial or full stop can be used for repairs. This not only causes the waste of raw materials and energy, but also causes the environmental pollution due to the spillage of flammable and explosive hazardous materials, endangering the safety of equipment and people. State-owned Dawn Machinery Co., Ltd. and relevant departments jointly developed a successful non-stop, with pressure, with temperature, strong injection plugging technology, has been in Liaohua, Tianhua and other field applications, and achieved good results. Liaoning Provincial Defense Science and Industry Office by the Ministry of Aviation Industry commissioned the technical appraisal of the results. Accreditation Committee agreed that: This technology is the first domestic technology to fill the gaps in modern plugging technology. It is characterized by non-stop, with pressure, with warm conditions for homework. This new technology has the advantages of rapid plugging, simple process, easy operation, good sealing, no stop, reduce energy waste, eliminate environmental pollution, significant economic benefits. In addition, prior to the plugging operation, there is no need for any treatment of the leaked parts, and the sealant does not adhere to the base metal, so it will not affect the subsequent disassembly and maintenance.
