Gear oil will deteriorate after a period of time, emulsifying viscosity will be reduced, and oil film can not be formed. This will lead to direct contact when gear teeth of reducer engage, thus wearing gears, which will lead to gear cracking seriously, affecting the normal operation of the mixer, so after using the mixer for a period of time, attention should be paid to maintenance and reduction. Speed machine.

I. Choice of Gear Oil

Gear oil can't be used as pseudo-inferior gear oil, pseudo-inferior gear oil, poor oil quality, low viscosity, and can't form mucous film which can not protect the gear. Choosing gear oil should have the following characteristics: suitable for working conditions such as concrete mixing station, good stability and high load carrying capacity, and strong corrosion resistance, oxygen resistance. Chemical and anti-emulsifying properties.

II. Timetable for replacement of gear oil

Use Phase - Work Time - Content

Running-in period - first 200 hours

Replacement of gear oil - second 500 hours

Normal service life

Change gear oil every 2500 hours

Three. Oil change step

1. Place a suitable container under the drain plug:

2. Remove the oil injection plug, oil mirror and oil discharge plug and release gear oil: (gear oil has a certain temperature, it is easier to discharge)

3. After all the oil has been discharged, replace the sealing ring of the oil discharging plug and install the oil discharging plug:

4. Add new gear oil according to specified oil level (central position of oil mirror), and do not mix with gear oil of different manufacturers or specifications.

5. Replace the sealing ring of the oil filling plug and install the oil filling plug.

IV. Oil consumption of various types of mixers
