In order to solve the problem that the oil pump can't come into the oil when the locomotive first starts up after overhaul or overhaul, the oil filter or the oil outlet pipe should be removed, and then the oil outlet hole of the body should be filled with the oil injector, and the oil filter or the oil pipeline leading to the oil indicator should be installed immediately. After starting, the oil will come up to the pump.
Fatigue Breakage Fault of Skillfully Drawing Hydraulic Tubing
Hydraulic tubing is prone to fatigue failure due to frequent changes in oil pressure and high oil temperature, resulting in frequent wall relaxation. In order to prolong the service life of hydraulic tubing effectively, it is better to use thin wire to fir into a spring and put it into the tubing as a support. The brake failure failure of skillfully discharged hydraulic brake locomotives should be carefully checked for the brake master pump and sub-pump, whether the brake oil is replaced on time, the air in the brake pipeline is completely eliminated, and whether the brake pedal meets the scientific height. The locomotive with pneumatic brake should check and adjust the maximum brake working pressure and check whether abnormal changes have taken place in the brake cup and hose.
Smart troubleshooting of blue smoke from diesel engine oil burning
The blue smoke from engine oil burned by diesel engine has not been solved after checking whether the piston group of cylinder liner is worn, whether the elasticity of piston ring is weakened, whether the oil in oil pan is excessive, and whether the oil level of air filter is too high. The potential cause should be checked whether the matching clearance between valve stem and valve guide is too large.
Excessive engine temperature caused by skillful drainage scale
Scale of engine cooling pump often causes engine temperature to be too high, accelerates wear of parts, reduces power and burns oil of lubricating pump. The most scientific soil method is to select two large luffa, remove the skin and seeds, clean and put into the tank, regular replacement can remove scale. The water tank should not be changed frequently, which will increase the formation of scale.
Skillful drainage of slow exhaust of inner tube
The inner tube of rubber should be slowly ventilated. The inner tube air should be exhausted as far as possible. A funnel made of cardboard should be inserted into the valve mouth. Two tablespoons of talc powder should be filled into the inner tube. After that, the valve core should be filled with air according to the standard. The talc powder diffusely adheres to the fetal wall after dispersing in the fetus, which can effectively prevent the slow release of small stomata, and the effect is very good.
