Second Used Sayaji Roll Crusher Hot Assembly

Here, we mainly share the common problems and key operation skills in the hot assembly process of the Second Used Sayaji Roll Crusher.

Preparation Of The Second Used Sayaji Roll Crusher Before Assembly

The matching dimensions, diameter, boss, round root, chamfer, etc. of the parts should be rechecked and the surface should be cleaned. The flat keys of the keyed parts are pre-fitted to the shaft and the keyway of the hole and fixed to the shaft. For the slant or tangential keys, the guide keys are used to ensure the mutual position of the keyways. Before the Second Used Sayaji Roll Crusher is hot-installed, the retaining ring, gasket and other components must be repaired and tested without errors.

The Second Used Sayaji Roll Crusher is positioned before hot loading, and the markings and direction indicators are marked at the same time. The assembly surface is coated with lubricating oil to reduce frictional resistance during loading. Before the Second Used Sayaji Roll Crusher is hot-packed, a measuring ruler is prepared to measure and confirm whether the heated workpiece is heated to the assembly condition. The ruler should meet the conditions of being light and not easily deformed, and the thermal expansion condition of the tested part can be accurately measured farther from the heat source.

The ruler can be made of metal rods or metal plates. The actual size should be equal to the nominal size of the measured part and the maximum interference at the fit and the minimum clearance necessary for assembly.

After the heated parts are heated, the measuring ruler can pass freely, and after re-inspection to confirm that the measured result is accurate, the heating can be terminated and the Second Used Sayaji Roll Crusher hot assembly operation can be performed.

Problems To Be Aware Of When Crushing Machine Hot Loading Operation

It must be hung or padded with a bracket or a barrier. It must not be in direct contact with the bottom of the box. The mating surface of the part must be completely immersed in the oil to avoid heat unevenness. The oil level should be less than 100mm above the edge of the fuel tank. flammable materials should be excluded around the fuel tank and fire prevention measures should be taken.

When heating, always pay attention to detect the rise of oil temperature, strictly control the oil temperature can not exceed the flash point of the oil, so as not to cause fire. The heating and holding time of the parts is related to the wall thickness, material, surface area and heating mode of the parts. Generally, the heating time of 10 minutes is required for 10mm; the holding time of 10min for each thickness of 40mm.

After the Second Used Sayaji Roll Crusher is hot-filled, the Second Used Sayaji Roll Crusher should be hot-loaded immediately. Parts related to the hot-packed parts of the Second Used Sayaji Roll Crusher should be completely cooled to normal temperature before assembly, except for special parts.

Method For Eliminating Axial Clearance In Second Used Sayaji Roll Crusher Hot Charging Equipment

After the Second Used Sayaji Roll Crusher is hot-packed, the axial gap occurs at the axial positioning shoulder of the wheel and the shaft due to the cooling shrinkage. The assembly is not in place and the positioning is unreliable. Therefore, it is necessary to eliminate the gap in the hot pack of the Second Used Sayaji Roll Crusher. Generally, the impact method, the bolt tension method, and the weight method are used.
