The reason and reasonable maintenance of the four major damage of Conveyor rolle
Clicks:3541 Date:12-15
1, soaking method: some small Conveyor roller are soaked in antirust grease, and the thickness of the oil film can be achieved by controlling the temperature or viscosity of the antirust grease. A method of adhesion to a layer of antirust grease on its surface.
2, brush coating method: when brush painting, pay attention to uniform coating on the surface of Conveyor roller, do not produce accumulation, also should pay attention to prevent leakage.
3, spray method: some large rust preventive substances are not suitable for oil immersion. Generally, the filter compressed air of about 0.7Mpa pressure is applied to clean the air in clean place. The spray method is suitable for solvent dilution antirust oil or thin layer antirust oil. This method must adopt perfect fire protection and labor protection measures.
Conveyor roller surface rust pretreatment methods:
Surface cleaning: cleaning must be combined with the properties of the Conveyor roller surface and the conditions at that time. Commonly used methods are solvent cleaning, mechanical cleaning and chemical treatment cleaning.
After the dry cleaning of the surface, the dry compressed air can be dryness with the filtered dry compressed air. Or dry with a dryer at 120~170 C, and finally dry with clean gauze.
Conveyor roller of the normal use of lubricating oil for brown and dark blue colors. If it is milky yellow, it shows that the oil is mixed with diesel or water, and it should be replaced in time. If it is dark black, it indicates that the oil has been deteriorated and must be replaced in time.
To be checked after oil stir drops on white paper (preferably filter paper), formation of oil spots, grease from the center outward after about 2 ~ 3 hours gradually spread, the formation of three concentric rings. The state of the oil can be identified based on the color, width and shape of the three regions.
Remove a little oil from the oil low shell, paint it on your finger, and twist it with your fingers and thumbs. If you feel that there are impurities in the oil or no sticky sense like water, even a sour or sour taste, the oil has deteriorated. If a small bright metal grinding can be seen on the fingers after grinding, it shows that the engine has serious wear parts, and at the same time, it is necessary to change the engine oil immediately.
When repairing and adjusting the dimension chain accuracy, according to the principle of datum coincidence, only one datum plane is used as the benchmark, that is, the design datum, and all the other surface repairs are based on this surface. This combination repair datum is easy to check precision and reduce accumulation error. For example, in the repair of a speed hydraulic coupler, the Conveyor roller body is often used as a reference.
1. suitable viscosity and good viscosity temperature characteristics
In order to make the spindle temperature not too high and the machine tool thermal deformation, affect the machining accuracy or bad lubrication should be based on Conveyor roller, Conveyor roller, the structure of lubricating oil spindle speed and Conveyor roller clearance of suitable temperature and the viscosity of winter is good, to prevent the work spindle temperature and environmental temperature change when the change of viscosity is too large to affect the lubrication performance.
2. good lubricity
In order to make the contact surface between the main spindle and Conveyor roller maintain a uniform oil film, but also in the spindle start or stop motion impact load oil film will not damage, maintain good lubrication performance has reduced friction and frictional heat, reduce the spindle temperature rise, ensure the machining accuracy of the role, with good lubricating property.
3. good antioxidation
When the spindle of machine tool is used for circulating lubrication, the main shaft Conveyor roller oil is used for a long time without deterioration, so it requires good oxidation resistance.
4. good rust resistance
Because the oil will inevitably be mixed into the condensed water or coolant of the machine in the working process of the main shaft lubrication system, it is required that the oil has good rust resistance.
