Sanding and dispersing mixing multi-purpose machine maintenance:
The V-belt should be equal in length and put into the transmission box.It is properly tightened.Tighten the bolts of the slide plate and close the cover.
If the equipment is not used for a long period of time,the power must be cut off,all cleaned,the lubrication parts are filled with oil,and the main shaft and oil cylinder are oiled to prevent rust.
The fuel tank uses 46#hydraulic oil,which is replaced every six months and the fuel tank is cleaned.The filter is cleaned once a month and once every two to three days after the oil change.
Gears,bearings,balls,shafts,bushings and oil cylinders of the rotating part of the dispersing machine are filled with oil once a week.If overheating or abnormal noise is found during use,it should be checked in time.
If the thermal relay is shut down due to overload,you need to press the"Reset"button of the thermal relay to continue operation.
The AC contactor is checked every six months,and the equipment is overhauled once a year.
The dispersing machine regularly inspects the wearing parts of the dispersing machine,such as bearings,oil seals,etc.,and immediately replaces it if found to be worn.
The pot of the disperser must be inspected once a day,and the record of the pot should be carefully recorded.
When the diameter of the blade is D,the diameter of the container is 3.4-3.9D,the height of the blade from the ground is 0.5-0.7D,and the filling height is 2.4-3D,which can achieve good dispersion effect.
Lubricants need to be added regularly to the columns and mixing shafts,usually once every shift.
The drive triangle belt is inspected irregularly.
Sand mill dispersing and stirring multi-purpose machine operating rules:
Check whether the oil level of the dispersing machine is filled to the specified position.Low should be added to the specified oil level and high should be placed to the specified position.
Check that the V-belt is tight.
Rotating the impeller by hand should be flexible and non-friction.
Check whether each fastener is loose and whether there are leaks in each sealing part.
Turn on the main motor of the disperser and check whether the rotation direction of the stirring is the same as that specified by the equipment.
Make sure that the above inspection work is correct before driving.
Place the impeller in the middle position of the disperser container,press the lower button,and lower to the lower position or the required position.
Both handles must be locked before driving.
Turn on the main motor and press the button at the speed required for operation.
Always pay attention to the current during the operation.If overload operation is found,stop the machine to check the cause,and continue to operate the disperser after taking measures.
Stop the main motor first to stop all the impellers.
Turn on the disperser up button to raise the main shaft impeller above the container and clean the impeller.
Installation and commissioning of sanding dispersing and stirring multi-purpose machine:
Generally,it is only necessary to install expansion bolts on a horizontal basis.If there is an explosion-proof requirement,you need to connect the cable between the electr
