Extrusion machine problem solving
Extrusion machines often encounter some faults in their operation. How to deal with problems when they occur, we must first understand the difficult problems in the fault.
In the extruder, if the mechanical parts fail, what are their manifestations?
In the extruder, if the mechanical parts fail, the main manifestations are as follows:
1. Overall fracture: It means that when the part is subjected to some external load, the dangerous section will have fatigue fracture, including the breakage of the guide column and the breakage of the bolt.
2. the residual deformation is too large: the parts will appear residual deformation, bending of the shaft, deformation of the gland and so on.
3. The surface of the part is damaged: it is corrosion, wear or contact fatigue on the surface of the part.
Common faults of the extruder, generally we can be divided into the following three aspects, as:
1. Defect failure: It is the failure caused by various defects in the design, installation and manufacturing process, such as unreasonable design.
2. sudden failure: This kind of failure is not time and fixed, mainly related to the operator's operating level, whether the machine is overloaded, the degree of cleanliness of the hydraulic oil and the quality of the parts.
3, wear-type fault: is the wear and tear caused by various frictions after the machine equipment has been running for a period of time, so it is necessary to do the maintenance work to extend the service life of the parts, but eventually it must be replaced to avoid other The component is damaged.
