The standard for maintenance and repair of vacuum kneading machines is to first clean, remove dirt, and scrub rust resistant vegetable oils after installation. Check each lubrication point and introduce lubricating grease (grease). Lubricating grease is generally used as 30-40 grade mechanical lubricating oil. After 500 hours of application, the new kneading machine needs to be oiled and replaced with new oil. Afterwards, during continuous work, the oil should be changed every six months (under an 8-hour working hour system). If the daily working hours are long, the oil change time can be moderately reduced. The feeding valve and its rolling bearings should be replaced with lubricating grease on time. For new feeding valves, sodium based lubricating grease should be used. 2. Before driving, it is necessary to check the tension level of the V-belt. When adjusting, the motor can be moved to an appropriate position according to the adjustment of the anchor bolts. The tightness and looseness of the transmission belt should be appropriate, and the transmission system should be checked, adjusted or replaced on time. The transmission chain should also be brushed with appropriate mechanical lubricating oil and cleaned on time. 3. Before trial operation, the power circuit and electrical equipment should be checked for safety. If it is an electric heating kneading machine, it is necessary to check whether its grounding system is reliable. Also, the kneading machine room should be cleaned and tidy, and the aviation parts should be rotated for 10-15 minutes. After confirming that the equipment is operating normally, funds should be invested in production and manufacturing. During the initial application of a new mobile phone transmission gear (including a reducer), the noise will be relatively loud, but after a period of operation, the noise will naturally decrease. 4. When using steam heating, valves and pressure gauges should be installed at the inlet of the pipeline, and the working pressure of the steam must not exceed the professional knowledge of the mixing tank application working pressure specified on the label. Steam pipelines are not allowed to leak. When the equipment is stopped, the gate valve should be closed and the reliability of the valve pressure gauge should be ensured. 5. If it is pre plasticizing the mixing paddle, it should be avoided to use flipping as much as possible. 6. The sealing part of the board wall does not need to have any leakage of raw materials. 7. After six months of operation, maintenance should be carried out to check the level of damage to spare parts and make appropriate adjustments and replacements.
