Do not make mistakes when repairing farm machinery

1. Cotton yarn rubbing parts cause burnt tile When a large diesel engine in a village is overhauled, maintenance personnel repeatedly scrub parts and the interior of the crankshaft with diesel soaked cotton yarn. Although the oil stain is removed, it appears to be very clean, but unexpectedly the cotton yarn is hung on rough parts. On the surface, after the machine works, the cotton yarn is flushed into the oil and is adsorbed on the oil filter net, blocking the oil from entering the oil channel, and the pump cannot oil, resulting in burning of tiles. Therefore, do not use cotton yarn for cleaning parts and brush with a brush. 2. Decrease in power caused by air filter on the stencil air filter In order to enhance the effect of filtering out dust, a certain machine has a red silk cloth covering the air filter, which is both beautiful and dust-proof. After the silk dust was adsorbed on the silk cloth, the air passage was blocked, causing insufficient air to enter the cylinder, causing black smoke and causing a drop in power. 3. A plastic tractor with fuel tanks has a small tractor to run. As the fuel tank cap is not tight, it is sometimes easy to spill diesel. The hand is covered with a plastic cloth on the fuel tank cap and tied with a rope. Because a small hole is covered in the fuel tank cap, as the diesel fuel is consumed in the tank, the atmospheric pressure inside the tank is not balanced with the outside pressure, and the oil supply is not smooth. The machine is not working properly. 4. The exhaust nozzle is used to accelerate the wear of the cylinder. There is a farm three-wheeled transport vehicle. The exhaust pipe is exhausted sideways and the exhaust gas is often sprayed on pedestrians. The operator turned the nozzle toward the ground, and the air filter sucked in the dust sand environment, which increased the dust sand entering the cylinder and accelerated the wear of the machine. 5. artificially reduce the water temperature to make the machine work worse. When a diesel engine is pumping water, the machine operator thinks that the water temperature is high or bad, and it is also troublesome to add water to the tank. Ingeniously, a plastic pipe is inserted into the water outlet of the pump to allow the water to automatically Into the tank. Because the machine is working at a low temperature for a long time, the diesel combustion condition is deteriorated, not only the fuel consumption is increased, but also because the silt accumulation in the tank is excessive, and the wear of the components is accelerated.
