Three sets of main reasons for mechanical failure can be considered:
1 . 1-Failure due to heat: In unfavorable thermal conditions, some parts fail and cause the equipment to malfunction. Temperature changes with a large range, for example, when turning on the device at a very low temperature and during heating, are one of these conditions.
2-This type of failure is generally easy to detect. . By using the timely replacement of equipment items and consumables, the repair and maintenance system of machines can be prepared to deal with these types of failures. Lubricating moving and rotating components such as shafts, axles, pins, and bushings, as well as making correct adjustments such as shims for components with permissible slack, are among the common methods for preventing these types of failures.
3-Erratic Failure: This type of failure is more difficult to identify and prevent than the previous two types. The time and circumstances of this type of failure cannot be precisely identified. . Most irregular breakdowns in heavy machinery occur under the influence of conditions such as excessive load on hydraulic and electronic systems.
