In addition to the routine maintenance such as filling butter into the vibration guide rod and checking, adjusting, cleaning and refueling of relevant parts, the extruder should also do the following maintenance work regularly:

1. According to the actual working time, the accumulative operation time is 1800 hours. It is necessary to change the lubricating oil in the reducer casing.

2. Check the oil level of the reducer regularly. If it is close to the lower limit, it should be replenishment to the upper limit immediately.According to the regulations, HL-30 gear oil is added in summer and HL-20 gear oil is added in winter. Mixed use of different grades of gear oil is strictly prohibited.

3. In case of oil seal failure and oil leakage, the oil seal shall be replaced in time.

4. The vibrator shall be maintained according to the following provisions:

A. The vibrator should be handled and operated with care to avoid damage by knocking.

B. The exterior of the casing shall be kept clean so as not to interfere with the heat dissipation of the motor.

C. If abnormal sound or vibration and coke odor are found during the operation of the vibrator, the power shall be disconnected immediately and the machine shall be shut down for inspection.

D. The lubricating grease of rolling bearing adopts 3 # compound calcium base grease. Pay attention to regular cleaning and replace it once in 150 ~ 200 hours after the vibrator runs.

E. Inspect the wear of bearing oil seals and other vulnerable parts regularly, and replace them in time if problems are found.

4. During the operation of the extruder, if there is poor quality of the plate and serious decline in the forming speed, it shall stop to check the wearing parts such as the mixing knife, wall plate and vibration plate;When replacing the agitator, symmetrical replacement should be done to ensure uniform feeding.

5. The machine shall not be placed in a leaky day.When not in use for a long time, the key parts should be protected with oil, and the two front walking wheels and the two back wall panels should touch the ground everywhere and be placed horizontally to reduce deformation.

6, in addition to the use and maintenance in accordance with the provisions of this book, the user should also make the extrusion press safe operation rules, the implementation of scheduled operation, to ensure the normal operation of the machine, in order to produce qualified products.
