Analysis of Maintenance Costs for High-pressure Spray Cleaning Machines

### I. Composition of Maintenance Costs

#### 1. Basic Maintenance Items

- Replacement of Filters and Seals: Regular replacement is required to maintain sealing performance and filtration efficiency (on average, every 3 - 6 months).

- Lubrication System Management: Periodic replacement of lubricating oil and cleaning fluid (approximately every 500 hours/once).

- Inspection of Key Components: Monitoring the status of core components such as high - pressure pumps, nozzles, and motors (routine monthly inspection).

#### 2. Optimization of Operating Costs

- Water Circulation System: Adopting a three - stage filtration device (magnetic separator + vortex sedimentation tank + precision filter element) reduces water consumption by 80% and decreases the frequency of filter element replacement.

- Energy - saving Design: The power consumption of some models is only 50% of that of traditional equipment, and long - term operation can save electricity costs.

### II. Key Points of Maintenance Cost Control

#### 1. Influence of Equipment Selection

- Intelligent Models: Fully automatic equipment equipped with a CPU control system has a low failure rate and supports remote diagnosis. The maintenance cost allocated to each cleaning is only 0.5 - 2 yuan.

- Traditional Models: Rely on manual maintenance, and the annual maintenance cost is approximately 2000 - 5000 yuan (including parts replacement).

#### 2. Optimization of Maintenance Strategies

- Preventive Maintenance: Performing basic operations such as cleaning and lubrication according to the manual can reduce 60% of sudden failures.

- After - sales Support: Choosing a brand that provides three - year free after - sales service can significantly reduce maintenance costs.

### III. Industry Comparison Data

- Fully automatic intelligent models: 3000 - 8000. The main cost sources are filter element replacement and system upgrade costs.

- Semi - automatic industrial models: 8000 - 15000. The main cost sources are manual inspection and replacement of vulnerable parts.

**Conclusion**: The maintenance costs of high - pressure spray cleaning machines are controllable. Through automated design and preventive maintenance, intelligent equipment can control the average annual cost within 5000 yuan, which is significantly lower than the traditional manual maintenance mode.
