Common Fault Analysis and Treatment of Piston Compressors     Analysis and Treatment of Insufficient Discharge Capacity   1. Intake System Issues    (1) Clogged Air Filter: Long-term operation leads to filter fouling, increasing suction resistance. Regular cleaning or replacement is required—recommended inspection every 500 operating hours.      (2...

Compressor seizure refers to a phenomenon where relative moving components become locked and unable to operate during compressor operation, typically caused by poor lubrication or contamination. This condition indicates compressor damage and most commonly occurs at friction surfaces including sliding bearings/crankshaft interfaces, cylinder/lower bearing contacts, and piston/cylinder rolling frict...

Compressed air is derived from moist air, and its pressure and temperature increase during compression, which can easily lead to the precipitation of liquid water, forming a gas-liquid two-phase flow. It may also contain oil contaminants, solid particles, and vibration interference from compressors. Its quality depends on dryness, dust content, and oil content, requiring drying (adsorption-type dr...

Air compressors are increasingly being utilized in the medical field. As an essential air supply device for dental units, oil-free compressors have been fully adopted abroad, providing oil-free, odorless, hygienic, clean, and dry green air sources. The development of dentistry in China will also drive another wave of growth for oil-free compressors.     It is reported that in dental trea...

1. For oil leaks in the air compressor, pay attention to the oil seal area and check whether the oil seal is cracked or if the inner lip is split or folded. Replace the oil seal if any of these issues are present. Inspect the contact surface between the oil seal and the main shaft for scratches or defects—replace if damaged. Check whether the oil return is unobstructed. Poor oil return can cause e...

Screw air compressor refrigerated air dryers are mainly divided into two types: refrigerated and adsorption-type. The most common one is the refrigerated air dryer (referred to as a "cold dryer"), which is one of the post-processing equipment frequently used by many customers when operating screw air compressors. So, what exactly is the function of a refrigerated air dryer?     The prima...

In recent years, permanent magnet variable frequency motors have been increasingly applied in the air compressor industry, with their market share rising significantly. Permanent magnet air compressors have become mainstream products, and many users are replacing traditional fixed-speed (constant-frequency) air compressors with permanent magnet models. But why has the permanent magnet air compress...

In daily use of compression equipment, the cleaning of the equipment is of particular concern, as its proper operation directly impacts production efficiency. Therefore, the removal of dirt on related components is especially critical. For general air compressor radiators, the accumulated grime not only comes from oil residues exacerbated by temperature changes during compression but also from env...
