What are the main vulnerable parts of piston air compressors?

The vulnerable parts of piston air compressors mainly include the following:

1. Air valve: including valve disc, spring, and lift limiter. The air valve is an important component for controlling the opening and closing of the airflow channel, and its working state directly affects the exhaust volume, exhaust temperature, power consumption, and operational reliability of the air compressor. The valve plate is subjected to the effects of airflow thrust, spring force, and inertia force during operation, and is prone to wear and deformation; The spring is used to timely close the air valve and alleviate the impact between the valve plate and the lift limiter.

2. Piston ring: The piston ring works repeatedly in a reciprocating compressor to achieve gas compression, but due to its small volume and small ring groove clearance, it is prone to thermal expansion and jamming, or wear due to friction with the cylinder.

3. Air filter: The air filter is used to filter the air entering the air compressor, preventing impurities from entering the interior of the machine. When the filter element is damaged, dirty, or has been working for a certain period of time (usually 1500 hours), it needs to be replaced.

4. Oil filter: The oil filter is used to filter the lubricating oil in the air compressor, preventing impurities from entering the lubrication system. It is generally recommended to replace it every 2500 hours.

5. Cylinder head: The cylinder head may have cracks or other damages and needs to be replaced.

6. Pressure regulating valve: When it loses its automatic control function under the specified pressure, it needs to be replaced.

7. Safety valve: When the specified safety pressure is exceeded, it will not exhaust and needs to be replaced.

8. Belt: The belt needs to be replaced when it is worn to the point of glue breakage or breakage.

9. Other instruments, such as temperature gauges, oil gauges, pressure gauges, etc., also need to be replaced when the pointer does not move or the reading is inaccurate.

In addition, there are internal structural components such as the crankshaft, connecting rod crosshead, and air valve, as well as auxiliary equipment and lubrication systems such as the body and cylinder. Although these components are not vulnerable parts, they also need to be regularly inspected and maintained to ensure the normal operation of the air compressor.

Please note that the above information is for reference only. The specific replacement cycle and standards for vulnerable parts may vary depending on different brands, models, and usage environments. Therefore, when using a piston air compressor, maintenance and upkeep should be strictly carried out in accordance with the maintenance manual and operating procedures provided by the manufacturer.
