Characteristics of Mechanical Failure of Small Pressing Machine

[qizhen0809]

The characteristics of the failure of small-scale road machinery and equipment show diversity, and according to different stages of use have different characteristics.
The failure characteristics of the initial stage of the small road press. The use of the initial failure rate is related to the use of manufacturing or maintenance quality and the use of the running period.If the road machinery manufacturing or repair quality (the equivalent of the distance) High, and can be used and maintained correctly. Then the initial failure rate is low. Otherwise the early failure rate will be high. The early failure of the coupling bolt is loose or loose; pipe joints loose or loose: residual metal chips or casting sand easy to plug the oil path or sandwiched in the relative movement friction in the tensile parts (such as hydraulic system in the implementation of the cylinder) Resulting in oil spills, adjusted clearance or pressure changes, so that mechanical parts can not perform the required capacity, some of the joints due to tight bolts and water leakage, oil leakage, leakage and so on.
Fault characteristics of normal stage of small road press. After the end of the mechanical road, into the normal use phase. Rolling machinery in this stage to run, as long as the provisions of maintenance and proper use, generally do not fail, even if the failure, but also random fault (this fault is hidden, maintenance or inspection is not easy to find), so the failure rate Very low, the curve is gently rising. If the road machinery in the normal period of failure, mostly accidental or due to use, maintenance due to improper.
