Quick repair and repair of agricultural machinery and oil products

First, a good way to quickly repair clever repair agricultural machine 1. Repair method of burning cylinder head gasket Tractor on the way, if the cylinder mat was burned a small hole, available asbestos red or hardcover cigarette paper inside the aluminum foil, the burned parts to fill stand up. If the burned area is large, you can cut a patch from the same part of the waste cylinder gasket to the burned area. 2. The chase easy elimination method The gear lever ball joint and the ball cover are worn out, resulting in the depth of the bottom end of the gear lever being not inserted into the fork groove, and the gear is slipping off the gear when the gear is engaged. At this time, the shift lever seat can be removed, and 1 to 2 washers can be trimmed with the waste fertilizer, and the gap between the shift ball joint and the ball cover can be eliminated. 3. Hand-shift automatic steering simple elimination method The steering tractor steering gear is engaged with the central transmission gear by the spring force of the steering spring. With the increase of the use time, the elastic force of the spring will be weakened, and the steering gear is easily disengaged from the central transmission gear and automatic steering occurs. Remedy: Adding spacers between the steering spring and the bearing can increase the spring force of the spring, and the automatic steering can eliminate it. 4. How to repair the oil spill in the tank When driving, discover oil spills from the tank, wipe it clean, and apply soap or bubble gum on the oil spill to reduce leakage. Use adhesives such as epoxy glue for temporary use. Plugging, the effect is better. 5. Repair of oil leakage from high-pressure tubing The bumps at both ends of the high-pressure tubing are connected with the concave surfaces of the fuel injector and the oil valve tight seat, and there is no gasket in the middle without oil leakage. If the contact surface wears, it will leak oil. At this time, a circular copper piece can be cut from the waste cylinder pad, and a small hole in the middle is placed between the convex head and the concave head to tighten the nut. The oil leakage problem is solved. . 6. Qiaozhi tire leaks slowly Take two tablespoons of talcum powder, dial the valve core on the tire, put the air inside the tire, use a cardboard shell as a funnel to insert the valve, talc powder poured into the inner tube, irrigation can not go When the paper funnel can be removed, turn the wheel and refill it until it is finished. Then install the valve core, sufficient gas. After filling, talc is dispersed in the fetus and diffusely attached to the inner wall of the femur, which can stop the leakage of tiny air holes. 7. Excluding water tank scales Two old, large, peeled and seeded old gourd pots are washed and put in a water tank. The scales are adsorbed on the loofahs. After one month, the loofahs are removed and the scales can be removed. 8. Cleverly unloading the bearing on the crankshaft of the engine The crankshaft of the engine is closely matched with the bearing on the box body. It is not easy to disassemble. Generally, when the crankshaft is heated to 60-80°C, the bearing is erected. The shaft is covered with a wooden board and can be knocked with a hammer. 9. Cleverly assemble the piston pin to heat the piston pin to 50~70°C. The piston pin hole is large and the piston pin is easy to assemble. 10. Cleverly bent high-pressure tubing The high-pressure tubing made of copper material is hard and does not bend easily. It can be reddish when the part to be bent, and immediately put into the water to cool, it will become soft and easy to bend. Second, a simple oil identification method 1. Look at the appearance of oil: In general, different types of oil have a different color appearance. When identifying, the color and size of the oil container are required to be the same, otherwise it has a great influence on the result of the observation and judgment. Carefully observe the appearance color of oil products. The light colors are mostly light-distillate and deep-refined oils. They are dark in color and are mostly residual oils, oils with low degree of refinement, or heavy distillate oils. 2. Smell the smell of oil. The odor of oil is generally divided into car flavor, kerosene flavor, diesel flavor, alcohol flavor, aromatic flavor, sourness and so on. The oil added with additives has a certain sourness; the oil with alcohol composition has alcohol taste; the light solvent oil has aromatic flavor. 3. Observe the thickening of the oil after shaking. By shaking the oil in a colorless glass bottle and observing the phenomenon of oil film hanging and the occurrence and disappearance of air bubbles, different grades of oil can be basically distinguished. Small-viscosity oils have more bubbles, rise faster, disappear faster, and have less hanging bottles; oils with large viscosity have less bubbles, slower rising speeds, and slower disappearance, but more bottles are hung in oil. 4. Touch the hard and soft conditions and smoothness of the touch oil. The refined oil hand feels smooth and smooth, and the poorly refined oil has a poor smooth feel. The grease and the hardness can be divided into different grades. The smaller ones are softer, and the larger ones are harder. Author: Agricultural Bureau of Zhangzhou City, Hebei Province

is very common in tattooing needles. There are four main types of needle groupings. Some have one

specific use and others can vary depending on how the artist is using it. Tattoo Needles that we carry
