Oil level check
Cut off the power supply to prevent electric shock! Wait for the reducer to cool down!
Remove the oil level plug and check whether the oil is full.
Install the oil level plug.
Inspection of oil
Cut off the power supply to prevent electric shock! Wait for the reducer to cool down!
Open the oil plug and take an oil sample.
Check the viscosity index of oil.
-If the oil is obviously turbid, it is recommended to replace it as soon as possible.
For pressure reducer with oil level plug
-Check the oil level to see if it is qualified.
-Install the oil level plug
Oil change
After cooling, the viscosity of the oil increases and it is difficult to discharge the oil. Therefore, the reducer should be replaced at the working temperature.
Cut off the power supply to prevent electric shock! When the reducer cools down, there is no danger of burning!
Note: The reducer should be kept warm when changing oil.
Put the oil pan under the oil drain plug.
Open the oil level plug, vent hole and oil drain plug.
Remove all the oil.
Install the oil drain plug.
Inject new oil of the same brand.
The oil quantity should be consistent with the installation position.
Check the oil level at the oil level plug.
Tighten the oil level plug and vent hole.
Matters needing attention in inspection and maintenance of heat conduction oil furnace
1, heat conduction oil furnace should be firmly installed on a stable foundation or pedestal, the oil in the oil drain tank should be cleared, and the cooling air should circulate smoothly. The foundation is unreliable, which will produce vibration and noise during operation and damage bearings and gears. When the transmission coupling has protrusions or gears and sprockets are used for transmission, it should be considered to install protective devices, and when the output bearing is subjected to large radial load, the reinforced type should be selected.
2, according to the provisions, install the device, to ensure that workers can easily close to the oil mark, exhaust plug, oil drain plug. After installation in place, the accuracy of installation position and the reliability of fasteners should be comprehensively checked in sequence, and they should be able to rotate flexibly after installation. The reducer is splashed and lubricated by the oil pool. Before operation, the user needs to remove the vent plug and replace it with a vent plug. Check the height of the oil level line according to different installation positions and open the screw of the oil level plug. Add oil from the oil level plug until the lubricating oil overflows from the threaded hole of the oil level plug. Tighten the oil level plug, and no-load test run can be carried out only after it is confirmed, and the time shall not be less than 2 hours. The operation should be smooth, free from shock, vibration, noise and oil leakage, and the abnormal situation should be eliminated in time. After a period of time, the oil level should be checked again to prevent possible leakage of the casing. If the ambient temperature is too high or too low, you can change the brand of lubricating oil.
3. When installing the heat conduction oil furnace, attention should be paid to the alignment of the transmission center axis, and the error shall not be greater than the compensation amount of the used coupling. Good centering can prolong the service life and obtain ideal transmission efficiency.
4. When installing the transmission parts on the output shaft, it is not allowed to knock with a hammer. Usually, the assembly fixture and the internal thread at the shaft end are used to press the transmission parts with bolts, otherwise the internal parts of heat conduction oil furnace may be damaged. It is best not to use rigid fixed coupling, because improper installation of this coupling will cause unnecessary external load, which will lead to early damage of bearings and even fracture of output shaft in serious cases.
