Tractor common fault emergency and maintenance
1, Qiao row of high-pressure tubing wear oil leakage tractor tractor high-pressure tubing at both ends of the nose and the injector, the oil valve leakage wear leakage phenomenon, can be cut from the waste cylinder mat round copper, a small middle The hole is smooth and smooth, and the pad can solve the urgency.
2. Inadequate fuel supply due to sudden bursts of oil supply during tractor operation. Insufficient oil supply during operation of the tractor. Air exhaust, replacement of the plunger, and injector are still not effective. It is the small steel ball in the injector pin of the injector. Grinding can not be caused by atomization. At this point, a small steel ball should be replaced, and if not, a bicycle flywheel steel ball can be used instead.
3, Qiao row steering wheel vibration, the front wheel swing head failure occurred steering wheel shake and shake the front wheel phenomenon, mainly due to improper front wheel positioning, the kingpin is too small. In the absence of instrument detection, try to add a wedge-shaped iron piece to the rear end of the plane of the leaf spring and the front axle support so that the front axle can be turned back and then the caster angle can be increased. After the trial run, it can return to normal.
4. In the tractor running with free gear shifting after the speed change, the free skip phenomenon occurs after shifting, which is mainly due to the wear of the fork shaft slot, weakening of the fork spring, and the excessive clearance of the connecting rod joint. At this time, repair slot should be used, fork spring should be replaced, and the gap between connecting rods should be reduced. After shifting into position, normal speed can be ensured.
5. Faults with poor performance of the oil pump to solve the problem that when the overhaul or overhauled locomotive starts the oil pump for the first time, the oil pump should not be pumped up. The oil filter or the oil discharge pipe should be removed, and then the oil hole should be used from the oil hole. Fill up the oil and immediately put on the filter or the oil pipe leading to the oil indicator. After starting, the oil will be pumped up.
6, Qiao row of hydraulic tubing fatigue fracture failure Hydraulic tubing due to frequent changes in oil pressure and high oil temperature, resulting in the frequent expansion of the pipe wall, easily lead to fatigue damage caused accidents. To effectively prolong the service life of the hydraulic hose, it is best to use a thin wire to burn into the tubing for support.
7, Qiao row hydraulic brake brake failure failure to carefully check the brake master cylinder and the sub-pump, whether to replace the brake oil on time, to completely eliminate the brake pipe air, and to see whether the brake pedal meets the scientific height. The pneumatic braking locomotive must check to adjust the maximum brake working pressure and check whether the brake cup and hose have abnormal changes.
8, Qiao row diesel engine oil burning blue smoke malfunction Diesel engine oil blue smoke, in addition to check the cylinder sleeve piston group wear, whether the piston ring elastic weakened, oil sump oil is added excessive, air filter oil surface is too high After the reasons have not been solved, attention should be paid to checking whether the gap between the valve stem and the valve guide is too large as a potential cause.
9. Qiao Drainage Causes Excess Engine Temperature Too High Failure of the engine cooling pump can lead to excessive engine temperature, accelerated component wear, reduced power consumption, and burned lubrication pump oil. The most scientific approach is to pick two large loofahs, remove the skins and seeds, and put them in the water tank after cleaning. Regular replacement will remove scale. Water tank water should not be changed frequently. Changing the ground will increase the formation of scale.
10, clever row of inner tube slow spread gas fault rubber inner tube slowly spread gas, inner air should be exhausted as much as possible, use a stiff paper to be a funnel to insert the valve, take two tablespoons of talcum poured into the inner tube, and then install the valve core according to the standard charge air . The talcum powder is diffusely adhered to the tire's sidewall after being dispersed in the fetus, which can effectively prevent the tiny pores from spreading slowly and effectively.
