Because agricultural machinery often operates in rural fields, it is inevitable that failures will occur. For a qualified farmer, grasping some necessary judgment methods for agricultural machinery failure can effectively avoid the failure of the farm machine in use and prolong his service life.
1. Power-off phenomenon When the agricultural machinery is running, if the horn does not sound, the light is not available, and the starter does not turn, the vehicle will be completely powered off. At this time, you can check whether the pile head of the battery is loose. Do not squash when inspecting. Use a pair of pliers to test the two pile heads. If there is no spark, then the pile head is loose and tighten with a wrench. If the pile head is tightened and cleaned, the power-off phenomenon remains. If it is not eliminated, check the connection of the two-pole conductors, such as contact failure and timely repair; if the battery has a single cell damage, use the copper wire to directly connect the good cells.
2. Damaged Fan Tape If the fan tape is damaged, it is mostly broken. Several ropes can be used for tightening the rope. The length and thickness of the rope should be similar to those of the original fan tape, but the rope should be in the middle and cannot be exposed, and then it can be tightly tied with iron wire; it can also be drilled at the two ends of the original fan tape. , with rough wire connected temporarily. The above method should test the engine for a few minutes and check if the fan rotation is normal.
3. Tire failure When the tire fails and there is no jack to replace the tire, you can open the bad tire to the dirt road, and then use wooden blocks or bricks, stones to stabilize the front axle or rear axle, digging under the tire to be removed Pit, make the tire vacant, can be replaced.
4. There are two main reasons why the flameout machinery is frequently turned off during operation: First, the diesel filter is dirty, the filter element is tightly packed with sludge, and the filter element can be removed and cleaned; the other reason is that the high pressure oil pump returns to the hollow screw and returns. The spring pressure of the oil valve is too small or the leakage of the oil is not closed tightly. The pressure in the pump body cannot be formed. A small cork can be used to cushion the spring to form a pressure, or the steel ball can be replaced.
5. If the valve spring breaks off, it can be installed and used if the broken spring is only broken; if the spring is broken at several places, the multi-cylinder machine can remove the adjusting bolt of the inlet and exhaust valve of the cylinder, and the valve is closed to make the cylinder. Stop working, cut off oil, replace spring.
6. If the radiator breaks and leaks into and out of the water hose, if it appears a little broken, use an adhesive cloth to coat the leaked water with soap, and then tie it tightly with the wire. If the crack is serious, cut it into two sections with a knife from the broken place of the hose. The bamboo or plastic pipe is placed between the hoses, and then tightly tied with iron wire, and then it can be installed. When the radiator core copper pipe has slight leakage, the leak can be clamped lightly with pliers to prevent it from leaking.
