Farm machinery repair small coup

Farm machinery repair small coup - 2019 02 - And now the rapid development of agricultural mechanization, agricultural machinery are becoming more common in the process of agricultural production, farm machinery repair also becomes crucial. The author introduce you to a few small agricultural machinery maintenance tips. Qiao 'three leakage prevention. Tractor engine gasket and the body contact area is uneven, untight seal, it often cause leakage, water leakage, oil leakage. Asbestos yarn can be smashed, and mixed with butter, then hit imaging dough stick together, and then put on the mat with the body, tighten bolts, can prevent the 'three leakage. In addition to the black smoke. Tractor exhaust smoke often present, unable to work, failure of the cooling water boiled. Important reason is that diesel engine's exhaust pipe and silencer carbon deposit is serious, the exhaust resistance increases, the air in the cylinder row of impurities, which can lead to inadequate intake, inadequate engine combustion, power down. Encounter this situation, simply remove the exhaust pipe and silencer, remove carbon deposit, can eliminate the fault. Taking the broken bolt. To break after a period of above parts outside of the bolts, can cut a aperture and in close the waste nut, bolt set in the exposed parts of the broken bolt, from hole by welding nut and bolt welded, and then using a wrench screw out; For the hollow bolt flush with part or after being broken, can use electric welding will break bolt end gradually tall, and then use less than scrap the diameter of the bolt nut, according to the above methods can also be agile spin out. Smart fill tank. If tractor tank leakage is lighter, can be in traditional Chinese medicine shop to buy a pack of 'catechu, and ground into powder, into the water tank, 30 ~ 45 litres of water tank can be put into volume' catechu '25 to 30 grams, start the engine 10 ~ 15 minutes,' catechu will melt, can play the role of bare. Qiao high-pressure tubing wear oil leakage fault. Tractors convex head and at the ends of the high-pressure tubing injector, delivery valve join appear wear leak phenomenon, from the exhaust gas cylinder MATS cut off a round of copper sheet, middle to plunge into a small hole grinding smooth, pad between the convex pit can be a lifesaver. Qiao row of sudden failure. The tractor in the operation of the oil supply is insufficient, eliminate air, replace the plunger, nozzle still doesn't work, after that is the injection needle injector in small ball plunger eccentric wear caused by injection cannot atomization. At this time should be in a grain of small steel ball, such as no bicycle flywheel ball instead of is also available. Qiao row steering wheel shake shake, the front wheel head failure. Appear steering wheel vibration shaking shook his head and nose wheel phenomenon, mainly is the wheel alignment is undeserved, kingpin caster Angle is too small. In the absence of instrument to detect, try in the leaf spring with the front axle bearing plane back-end gasser wedge plate, after the front axle, increase the kingpin caster Angle, again returned to normal after commissioning. Qiao variable freedom jump after gear fault. In the operation of the tractor, freedom appears after the variable speed jump phenomenon, mainly is the groove wear, fork fork shaft parts, such as weak joint clearance is too large. At this time should be used to repair positioning groove, replace the fork spring, to reduce the connecting rod joint clearance, shift are obtained to ensure the normal speed. Qiao row about the worse performance of oil pump failure. To solve the problem of locomotive of overhaul or repair after the first start the machine oil pump pump don't come up to the problem of oil, oil filter or flowline should be uninstalled, then use lubricator oil from the body out of the oil hole is filled, immediate superior filter or lead to the oil pipe, oil indicator when activated, will pump up the oil. Qiao row tube slow leak failure. Rubber tube slow leak, inner tube air should be put as far as possible, made a funnel cardboard insert valve, take two tablespoons talcum powder into the inner tube, after the completion of loading on the valve core according to the standard exert. Talcum powder inside the tire to scatter diffuse adhesion in the sidewalls, which can effectively prevent tiny voids slow leak, the effect is very good. Qiao row hydraulic tubing fatigue fracture failure. Hydraulic tubing frequent change due to the oil pressure and oil temperature is high, the tube wall relaxation is frequent, appear easily fatigue wreck accident. To effectively extend the service life of hydraulic oil pipeline, it is best to use thin wire burning spring inside the tubing as support. Qiao hydraulic brake of locomotive brake failure. Carefully check the brake master cylinder and wheel cylinder, whether to replace the brake fluid, eliminate the air brake pipe, and the brake pedal to see whether conform to the scientific level. Pneumatic brake adjustment should examine locomotive brake work pressure, largest brake cup and examine whether the hose abnormal changes. Blue smoke coming qiao row diesel engine burning oil fault. Blue smoke coming burning diesel engine oil, in addition to check whether the cylinder piston group is wear, piston ring elasticity is reduced, oil sump oil whether or not to add too much, air filter oil level after higher reason still did not solve the problem, we should pay attention to check whether the fitting clearance of valve stem and valve guide is too large a potential cause. Qiao scale caused more engine overheating fault. Engine cooling pump scale would lead to the engine temperature is too high, speed up parts wear and tear, lower power, consumption of lubricating oil pump. The most scientific way of soil is: choose two big towel gourd, remove skin and seed, into the tank after cleaning net, change can be scaling on a regular basis. Water tank water is often change, change frequently will increase the formation of scale.
