Maintenance method of blender:
1. Maintain the cleanliness of the body and remove dirt and obstacles on the body.
Check THE OIL MATERIAL, circuit and control equipment at each lubrication place, and add lubricating oil as required.
Before the work of each shift, add water to the mixing cylinder and idling for 1-- 2min, while checking the reliability of the clutch and brake device.
4. During the operation of the concrete mixer, it is necessary to check whether the noise of the motor, reducer and transmission gear is normal and whether the temperature rise is too high.
After each shift, the concrete mixer should be carefully cleaned.
6, the equipment fixed foundation needs to have enough rigidity, to ensure that there is no resonance, no shaking.
7. The maintenance of the mixer is mainly the maintenance of the reducer, so it is mainly used and maintained in accordance with the above part.
8, the blade is not completely immersed in the liquid is strictly prohibited empty operation, so as not to cause danger and equipment damage.
9. If there is abnormal sound, temperature rise and shaking of the equipment after starting up, it should stop running immediately and check and deal with it.
10. Before starting the mixer, please make sure that the foundation bolts and screws of each part are completely fixed.
11. For high speed or large capacity stirring operation, the bottom or middle of the shaft body should be equipped with a positioning device to reduce the failure probability caused by the shaking of the shaft body.
12. According to different industries, different working environments and different mixing purposes, the selection of the mixer is also very important. Improper selection is easy to cause the low service life of the mixer and the high failure rate.
Method of prolonging life of mixer:
(1) When the life of the bearing ends, the vibration and noise of the motor operation will increase significantly. When the radial clearance of the bearing reaches the following values, the bearing should be replaced.
(2) The operating environment should always be kept dry, the surface of the motor should be kept clean, and the air inlet should not be hindered by dust and fiber.
(3) Good lubrication should be ensured during the operation of the motor.
(4) When replacing the winding, the form, size, number of turns and wire gauge of the original winding must be recorded. When these data are lost, they should be obtained from the manufacturer to change the original design of the winding, which often deteriorates the performance of a motor or several items, or even can not be used.
(5) When the thermal protection of the motor continues to operate, it should be found out whether the fault comes from the motor or overload or the setting value of the protection device is too low. Only after the fault is eliminated can it be put into operation.
(6) When removing the motor, the rotor can be removed from the extended end or the non-extended end of the shaft.
