22KW High Pressure Booster Compressor

To ensure the safety of both operators and the equipment, the unit is typically equipped with multiple protection devices:

• Pressure protection: Includes safety valves at various stages and automatic shutdown/alarm systems triggered by overpressure in the intake or discharge lines.
• Temperature protection: Real-time monitoring of discharge temperature to prevent lubricant coking or component damage caused by excessive heat.
• Oil pressure and water flow protection (for water-cooled models): Ensures adequate lubrication and proper cooling water circulation.

Failure to reach the set discharge pressure is usually caused by gas leakage, insufficient intake, or system mismatch issues. Common causes include:

• Valve failure: Wear, deformation, or breakage of intake/discharge valve plates, or carbon deposits/foreign objects on sealing surfaces, leading to imperfect valve closure and gas backflow.
• Piston ring and cylinder liner wear: Severe wear or excessive clearance in high-pressure stage piston rings causes high-pressure gas to leak downward (blow-by), reducing effective discharge volume and pressure.
• Intake system obstruction: Severe clogging of the intake filter or piping results in insufficient intake volume, thereby affecting the final discharge pressure.
• Inter-stage cooling and pressure leakage: Minor leaks in stage safety valves, poor sealing at pipe joints or flanges, or a damaged discharge check valve. Excessive downstream gas demand: Actual on-site gas consumption exceeds the compressor's rated discharge capacity.

A sudden increase in operating noise usually signals loose or worn mechanical components or abnormal airflow. It is recommended to focus inspections on the following areas:

• Valve assembly: Check for broken valve plates or failed springs. Valve plate damage is often accompanied by abnormal metallic "clacking" sounds or hissing airflow noises.
• Moving mechanism clearances: Check for excessive clearance-caused by wear-in connecting rod bearings (big/small ends), crosshead pins, or crankshaft main bearings, which can produce mechanical knocking sounds.
• Loose fasteners: Check for loose cylinder head bolts, frame anchor bolts, or stage piping supports that could cause resonance or component-on-component impact.
• Poor lubrication: Check the oil pump's operating status and oil level. Insufficient lubrication or oil degradation can lead to dry friction between moving parts, resulting in sharp, abnormal noises.

To ensure long-term, stable operation and facilitate future maintenance, the installation environment must meet the following requirements:

• Solid and level foundation: The equipment should be installed on a level, solid concrete foundation and secured with anchor bolts in accordance with specifications; specialized vibration-damping pads should be installed if necessary to minimize vibration transmission.
• Proper ventilation, temperature, and humidity: The installation site must provide adequate ventilation and heat dissipation (especially for air-cooled models); the ambient temperature should generally be maintained between 5°C and 40°C, and the unit should be protected from direct sunlight and rain.
• Sufficient clearance: Adequate space (typically at least 1 meter) must be reserved around the equipment to facilitate routine inspections, filter element replacement, air valve removal, and major overhaul operations.
• Environmental cleanliness: Airborne dust, corrosive gases, and moisture should be minimized; if the operating environment is poor, an intake pre-filtration device must be installed to prevent accelerated mechanical wear.
