1. Must use a suitable quality oil quality, which is the key to ensure the normal operation of the engine. 2. Temporarily adopt alternative oil products to enhance observation. If oil supply is not timely or there is no suitable oil product, the substitute oil product can be used temporarily. However, observation must be strengthened during use. Pay attention to the quality of the oil product and whether the oil filter is clogged. Situation, found problems with timely parking treatment. 3. The oil with the proper viscosity should be selected according to the local temperature and the oil with the right viscosity should be selected. The view that the bigger the viscosity is better is wrong, because the viscosity is too high, the oil flow is too slow at the start, and it is easy to make the wear of the parts more serious. It even caused a tile burning accident. 4. When draining the oil, drain the waste oil to prolong the service life of the engine. When replacing the oil, the old oil must be completely drained to avoid contaminating the newly added oil, causing the new oil to deteriorate rapidly and causing corrosive engine wear. Under normal circumstances, put the waste engine oil at high temperature, and then add washing oil (85% of common motor oil and 15% of gasoline are mixed). After starting, it is idling for 10 minutes, then released, and finally cleansed again. Oil can be. 5. Keep the crankcase well-ventilated The gas that enters the crankcase from the combustion chamber is corrosive, which can oxidize and deteriorate the engine oil and contaminate the engine. Therefore, the crankcase must be well ventilated. 6. Maintaining a normal oil level When the oil level is insufficient, not only will the engine oil be spoiled, but the machine parts will be burned due to lack of oil. Conversely, if there is too much oil, the oil will be along the cylinder wall and between the piston rings. The gap broke into the combustion chamber, causing the engine to burn oil. In addition, the oil level is too high, which increases the agitation resistance of the oil and increases the fuel consumption and wear. 7. Regularly maintain the oil filter regularly check and maintain the oil filter, replace the filter element in time, the driver should be aware of. 8. Regularly or qualitatively change the oil quality of any oil, after using a certain mileage, some physical and chemical indicators change, will cause damage to the engine, resulting in failure, so according to the oil changes regularly according to the quality of oil change. 9. When using thickened engine oil, the oil pressure is slightly lower than that of the same grade of general engine oil. Because thickened oils have good viscosity and viscosity, they have a higher viscosity at high temperatures and a lower viscosity at low temperatures. The viscosity is slightly lower in the normal engine temperature range, so a lower pressure is normal. 10. When using all-year general-purpose engine oil or thickener engine oil in winter, do not add ordinary engine oil to avoid affecting low-temperature startability. Add ordinary motor oil gradually in the spring or when changing to general engine oil. Sheet metal fabrication processing is formed by laser cutting or stamping process, shear and bending, bending, bending, welding, riveting. The Sheet metal fabrication used are cold-rolled plate (SPCC), hot-rolled plate, galvanized plate (SHCC) (SECC, SGCC), copper (CU) brass, copper, beryllium copper, aluminum (5052), stainless steel. Sheet metal fabrication processing steps: according to the parts drawing (3D) expanded into a plan (2D), laser cutting or die stamping shape, CNC punching each bending part, should pay attention to the direction of the burr of the workpiece. Then the students are welded or riveted (some). Surface treatment after processing: electroplating, passivation, sand blasting (powder), anode treatment. Products are generally made for the connection and the outer cover. Applications in robotics, drone, communications, medical devices, industrial automation equipment.
