Fluoroplastic lining equipment may encounter various malfunctions during use. Here are some common causes of malfunctions and their analysis:
1、 Damaged lining layer
Corrosion:
Although fluoroplastics have excellent corrosion resistance, corrosion may still occur under certain extreme conditions, such as extremely high concentrations of corrosive media, high temperature and high pressure environments.
Corrosion may cause thinning, perforation, or detachment of the lining layer.
Mechanical damage:
During installation, debugging, or operation, improper operation or external object impact may cause scratches, cracks, or damage to the lining layer.
Thermal stress:
The thermal expansion coefficient of the lining layer is different from that of the substrate material, which may generate thermal stress during temperature changes, leading to the detachment or cracking of the lining layer.
2、 Sealing failure
Seal aging:
Seals (such as O-rings, gaskets, etc.) may fail due to aging, hardening, or wear during long-term use, leading to leakage.
Sealing surface damage:
Sealing surfaces (such as flange surfaces, shaft seals, etc.) may be damaged during installation or operation, resulting in inadequate sealing.
Improper installation:
Improper installation of seals (such as being too tight or too loose, misaligned, etc.) may also lead to seal failure.
3、 Equipment performance degradation
Blockage:
Impurities, particles, and other substances in the medium may clog the inlet and outlet of equipment, pipelines, or filters, leading to a decrease in flow rate or an increase in pressure.
Wear and tear:
The rotating components of the equipment (such as bearings, shafts, etc.) may experience performance degradation due to wear and tear during long-term operation, resulting in increased vibration, noise, or reduced efficiency.
Scaling:
Some components in the medium may form scale on the inner wall of the equipment, affecting the heat transfer efficiency or fluid channels of the equipment.
4、 Electrical malfunction
Motor malfunction:
The motor may be damaged due to overload, overheating, short circuit, and other reasons, causing the equipment to malfunction.
Control system malfunction:
The sensors, actuators, and other components of the control system may fail due to malfunctions, causing the equipment to be unable to operate according to preset parameters.
5、 Other faults
Vibration:
The equipment may experience vibration during operation due to imbalance, looseness, and other reasons, which can affect the stability and service life of the equipment.
leak:
In addition to leakage caused by seal failure, leakage may also be caused by loose pipeline connections, cracked welds, and other reasons.
Noise:
The equipment may generate noise during operation due to fluid flow, mechanical friction, and other reasons, which can affect the working environment and personnel health.
Corresponding preventive measures and maintenance methods can be taken for the above fault causes, such as regular inspection, maintenance, replacement of damaged parts, optimization of operating parameters, etc., to ensure the normal operation and prolong the service life of fluoroplastic lining equipment.
