Whether a special maintenance unit is required for air compressor maintenance shall be comprehensively judged according to the equipment type, enterprise technical capability and cost-effectiveness. However, it is recommended to select a professional maintenance unit to ensure stable operation of the equipment and prolong its service life.. The following is a detailed analysis of this issue:
the Necessity of 1. a Professional Maintenance Unit
- technical Professionalism
air compressor as industrial core equipment, its maintenance involves mechanical, electrical, automation and other fields of knowledge. Professional maintenance units usually have: - technical Team: Composed of experienced engineers, can quickly diagnose and solve complex faults.
- Device Resources: Equipped with professional testing tools (such as vibration analyzer, infrared thermometer) and spare parts library, can efficiently complete maintenance tasks.
- Training system regular skill training for technical personnel to ensure that they master the latest maintenance technology.
- Security
air compressor in high temperature, high pressure environment operation, if the improper maintenance may cause explosion, fire and other serious accidents. Professional maintenance unit: - strict compliance with safety regulations: Reduce the risk of accidents, such as power-off operation, tag locking, use of protective equipment, etc.
- Provide safety training: Provide safe operation guidance to enterprise operators to enhance overall safety awareness.
- Cost-effectiveness
- reduce maintenance costs professional maintenance units reduce sudden equipment failures and avoid downtime losses through preventive maintenance. For example, regular replacement of the filter element can prevent blockage of the oil circuit and extend the life of the compressor.
- Optimize spare parts management: According to the use of equipment to develop spare parts procurement plan, reduce inventory backlog and capital occupation.
- Extend equipment life: Through system maintenance, the service life of the air compressor can be extended by 30%-50%, reducing the frequency of equipment updates.
The Feasibility of Self-maintenance of 2. Enterprises
- applicable Scenarios
- small Business if the number of air compressors is small, the structure is simple (such as piston air compressor), and the enterprise has the ability of mechanical maintenance, it can complete the basic maintenance (such as lubricating oil replacement, filter element cleaning).
- Emergency when the professional maintenance unit cannot arrive in time, the enterprise can first carry out simple treatment (such as turning off the power supply and discharging the condensed water) to prevent the fault from expanding.
- Potential Risks
- inadequate technology: Non-professionals may cause equipment damage or safety accidents due to improper operation. For example, failure to tighten the bolts to the specified torque may result in leakage in the pipeline.
- Quality of spare parts: Self-purchased spare parts may not meet the original factory standards, affecting equipment performance. For example, the use of inferior filter elements may cause excessive oil content in compressed air and pollute the production environment.
- Incomplete maintenance: Focusing only on surface problems and ignoring deep hidden dangers (such as aging of motor insulation) may cause major failures.
Recommendations 3. selecting a maintenance unit
- qualification audit
- confirm whether the maintenance unit has relevant qualifications (such as special equipment installation, renovation and maintenance license, ISO 9001 quality management system certification).
- Check its service cases and customer evaluation, and give priority to the units that have cooperated with enterprises in the same industry.
- Service Content
- all-inclusive service: including daily inspection, regular maintenance, fault repair, spare parts supply, etc., suitable for enterprises lacking technical team.
- On-demand services: Only provide maintenance when the equipment fails, suitable for enterprises with basic maintenance capabilities.
- Customized scheme according to the equipment model, the use of the environment (such as dust, humidity) to develop a personalized maintenance plan.
- Cost comparison
- all-inclusive service: Charges by year or by the number of equipment units, which are higher but can transfer risk.
- On-demand services: Pay-per-view, suitable for enterprises with low equipment failure rate, but need to reserve emergency funds.
- Self-maintenance: Only need to pay the cost of spare parts, but need to bear the technical deficiencies and safety risks.
4. Case Reference
- a chemical enterprise: With 10 screw air compressors, the equipment failure rate is reduced by 60% and the annual maintenance cost is reduced by 40% after the all-inclusive maintenance service is selected.
- a food factory: Self-maintenance of 2 piston air compressors. The compressor was stuck due to failure to replace lubricating oil in time. The maintenance cost was as high as 50000 yuan and the production was stopped for 2 days.
