Maintenance Methods of Furnace Tap Hole Machine

Select suitable cleaning oil

Clean oil plays the role of pressure transmission, lubrication, cooling and sealing in the furnace tap hole machine. Improper selection of cleaning oil is the main reason for early failure and durability decline of furnace tapping machine. Clean oil shall be selected according to the needs of the machine. When alternative oil needs to be used under special circumstances, its performance shall be the same as that of the original brand. Cleaning oils of different brands cannot be mixed to prevent chemical reaction and performance change of cleaning oil. Dark brown, milky white and peculiar smell cleaning oil is deteriorated oil and cannot be used.

Prevent solid impurities from mixing into the furnace tapping machine

Pure clean oil is the life of the opening and plugging machine. There are many precision coupling parts in the opening and plugging machine, such as damping holes, gaps, etc. If solid impurities invade, the precision coupling will be strained, hairpin, oil duct blockage, etc., which will endanger the operation of the opening and plugging machine. The ways for general solid impurities to invade the opening and plugging machine are: clean oil is not clean; Dirty refueling tools; Careless refueling, repair and maintenance; Desquamation of hydraulic components, etc. Solid impurities can be prevented from invading the system from the following aspects:

The cleaning oil must be filtered and filled, and the refueling tools shall be reliably cleaned. Do not remove the filter at the fuel tank filler for the sake of refueling speed. Refueling personnel shall use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil.

If it is necessary to use wiping materials and hammers, wiping materials without fiber impurities and special hammers with rubber attached to the striking surface shall be selected. Hydraulic components and hydraulic hoses shall be carefully cleaned and assembled after drying with high-pressure air. Select the filter element with intact package (if the inner package is damaged, even if the filter element is intact, it may be unclean). Clean the filter while changing the oil, and carefully clean the inner bottom of the filter housing with wiping material before installing the filter element.

Preparation before Metallurgical FurnaceTapping Machine Startup

Check whether there are obstacles on and around the track of the furnace tapping machine main body and plugging machine trolley. If there are obstacles, clean them immediately.

Check that all fastening bolts are fastened.

Check that all operating handles are in the stop position.

Check each oil pipe to ensure there is no damage or leakage on site.

Check whether the oil level in the oil tank is normal. When the oil level is too low, anti-wear and pressure oil must be added in time.

Check all lubricating parts and add lubricating oil.

Check whether all parts of the furnace tapping machine operate normally, and test run the trolley and oil cylinder.
