Installation Skills Of Agriculture Machinery Parts
Installation skills of Agriculture Machinery Parts
In the maintenance of agricultural machinery, some parts because of the structural constraints, the assembly of a little inadvertently will be installed reverse, to the agricultural machinery left potential trouble. To do well the assembling work of agricultural machinery parts can not only improve the working efficiency of the machine, but also can eliminate the malfunction effectively. Here are some key parts of the assembly techniques:
CYLINDER gasket. If there is oil hole, it must be aligned with the corresponding oil channel holes on the fuselage and cylinder head, so as to avoid the friction caused by the breaking oil of the valve on the cylinder head. No oil channel hole and positive and negative shapes are the same, Agriculture Machinery Parts to the cylinder head material to determine: for the aluminum alloy cylinder head, the cylinder head side should be facing the cylinders; for the cast iron cylinder head, the cylinder head side should be facing the cylinder head.
pistons and piston rings. A piston marked with upwards arrows at the top shall be installed in the direction specified in the marking, and the small notch adjacent to the piston top swirl pits or pits shall be pointed toward the side of the injector to ensure that the gas is uniformly mixed. Agriculture Machinery Parts When assembling the piston ring, the top part is "Up" and "up" such markings shall be upward, the top unmarked twisted ring, the inner circle or chamfer shall be downward; chrome ring (shell shiny) should be installed in the first piston ring groove, each ring opening should be staggered 120~180度 to ensure its sealing effect.
The connecting rod and the connecting rod cover. The connecting rod of the horizontal diesel engine is divided by 45 degree, and the section faces downward to improve the stress of the connecting rod bolts. The connecting rod cover and the connecting rod are mated, and the matching marks should be on the same side to ensure the roundness and cylindricity of the connecting rod bearings meet the requirements.
MAIN bearing cover, bushing, bushing. The main bearing cover and the body bearing seat are mated to the boring process, should be matched by the matching mark, not arbitrarily interchange or change assembly direction, so as to avoid damaging the main bearing seat hole coaxial and dimensional accuracy. Agriculture Machinery Parts The bushing or bushing with oil holes shall be aligned with the corresponding oil channel holes on the bearing seat and the bushing hole to ensure that the circuit is unblocked.
Drive shafts and transmission chains. The transmission fork at both ends of the drive shaft shall be in the same plane, so as not to cause torsional vibration and damage of the transmission parts. The transmission chain adopts the spring clamp, so the opening end direction is opposite to the chain movement direction, lest the collision in the movement fall off.
Drive wheels. The driving wheel is marked with an upward arrow, which should be directed toward the direction of the tyre in advance; unmarked, from the rear of the locomotive look at the driving wheel, Agriculture Machinery Parts its "eight" glyph or "person" pattern of the top should be facing up.
Cylinder head bolts. If the end of the bolt is a coarse tooth thread, and the other one is a fine tooth thread, the coarse tooth thread ends should be screwed into the body; if the ends of the bolts are fine teeth, the shorter end should be screwed into the body to ensure that the cylinder head is compacted.
Oil pump and fuel injection pump. The machine pump uses the planetary rotor type, should turn the outer rotor chamfer toward the pump body, lest the engine oil in the pump circulation and reduces the pump oil pressure. Agriculture Machinery Parts A crescent-shaped positioning groove on the plunger sleeve of the injector nozzle shall be positioned on the pump body, and the sign (or return tank) of the plunger shall be mounted upward to avoid the oil or diesel engine "rook".
