Montáž a odladění hydraulického systému kovová tavící pec

The hydraulic drive device has the advantages of small size, flexibility, lightness and convenient control and operation. Most crucible and groove induction furnaces use hydraulic tilting systems. The design of the oil pump station should consider reliable use and convenient maintenance. There are melting sections with multiple metal melting furnaces, and the hydraulic systems of each furnace should be able to borrow each other to reduce the time of forced shutdown due to maintenance of the hydraulic system.

Stanice olejového čerpadla je obecně instalována na základně s určitou výškou, což je vhodné pro vypouštění oleje z olejové nádrže při údržbě a zároveň je výhodné pro bezpečnou výrobu. I když dojde k vážné havárii netěsnosti pece, olejová nádrž může být chráněna před roztaveným železem. Při instalaci ropovodů musíme také vycházet z nejhorších podmínek: vyvarujte se kdykoli setkání s vysokoteplotní železnou kapalinou, aby nedošlo k rozšíření havárií.

Eliminating the oil leakage in the hydraulic system is a relatively difficult task. This starts with improving the installation quality. The joints of the oil pipeline that do not need to be disassembled should preferably be connected by welding. The weld should be dense and free of leakage. After welding, clean the inner wall without leaving welding slag and oxide scale. For oil pipeline joints with threaded connections, sealing and leak-proofing should be considered in the structure. Take corresponding auxiliary measures during installation, such as adding anti-leakage paint, to reduce the possibility of oil leakage during operation.

Po instalaci hydraulického systému by měla být provedena tlaková zkouška celého systému. Metodou je propustit 1.5násobek pracovního tlaku oleje, udržovat jej po dobu 15 minut, pečlivě zkontrolovat každý spoj, svar a spoj každé součásti, pokud dojde k nějaké netěsnosti, měla by být přijata opatření k odstranění jednoho po druhém.

After the furnace body, water cooling system, and hydraulic system are installed, the furnace body tilting test should be carried out, and the overall inspection of the furnace installation quality, such as whether the hydraulic control system is flexible and reliable, whether each action is correct; whether the furnace body and furnace cover are operating normally ; When the furnace body is tilted to 95 degrees, whether the limit switch plays an insurance role, and adjusts the pressure and flow of the hydraulic system to make it in a good working condition. While tilting the furnace, check the installation quality of the moving joints of the water-cooling system. No water leaks or hinder the tilting of the furnace body; check the hoses of the hydraulic and water-cooling system, observe whether the length is appropriate when the furnace body is tilted, and make appropriate adjustments if necessary. Adjust; check whether the drainage system can work normally when the furnace body is tilted. If any deficiencies are found, corresponding measures should be taken.
