LPG Compressor Working Principle & Common Troubleshooting|A Technical Guide by MINNUO Compressor
1. Introduction LPG (liquefied petroleum gas) compressors are critical pressure-boosting equipment widely used in LPG filling stations, storage terminals, petrochemical plants, cylinder filling, tank unloading, and gas recovery systems. This guide from MINNUO Compressor explains the working principle, structure, common failures, troubleshooting, and routine maintenance of LPG compressors to ensure safe, stable, and efficient operation.

Why Is Your Screw Compressor Overheating? Common Causes and Diagnostic Steps
A screw compressor that shuts down on high temperature once may be an inconvenience. One that does it repeatedly is a machine in distress. The thermal protection system that trips the compressor is not there to disrupt production. It is there to prevent the machine from destroying itself. When discharge temperature exceeds the safe limit […]
Industrial Diaphragm Compressor: Oil-Free, High-Pressure, Zero-Leak Precision Gas Compression Equipment
In high-end industrial fields such as petrochemicals, hydrogen energy, semiconductors, pharmaceuticals, food, and special gas filling, gas compression often faces three strict requirements: ultra-high purity, high safety, and ultra-high pressure. Traditional piston and screw compressors struggle to meet strict conditions such as oil-free operation, zero leakage, and corrosion resistance. The industrial diaphragm compressor has become […]
Oil-Free vs. Oil-Flooded Compressor: What Is the 10-Year Cost Difference?
Two compressors sit on a factory floor. One is oil-flooded. The other is oil-free. They deliver the same flow, at the same pressure, to the same header pipe. They both run 6,000 hours a year. They both get serviced on schedule. After ten years, one has cost its owner significantly more than the other. The […]
Application Practice, Selection Key Points and Industrial Upgrading Path of Screw Air Compressors in Cement Plants
As the core power equipment of industrial air supply systems, screw air compressors are widely applied in the whole process of cement production due to their outstanding advantages such as stable and continuous air supply, reliable operation, convenient maintenance and strong adaptability to harsh working conditions. Links including raw material crushing, raw meal homogenization, kiln […]
What Compressed Air Quality Does a Pharmaceutical Plant Actually Need?
Walk into a pharmaceutical plant and ask where compressed air touches the product. The list is longer than most people expect. It moves capsules through filling machines. It powers tablet presses. It aerates fermentation broths. It cleans bottles before filling. It dries vials after washing. It actuates valves on clean-in-place systems. In every one of […]
Petrochemical Compressor Selection Guide: Safety, Efficiency & Life-Cycle Cost
In the petrochemical industry, compressors are known as the “heart” of the process system, widely used in feed gas boosting, process gas circulation, air separation for nitrogen/oxygen production, flare gas recovery, LPG transportation and other critical links. Petrochemical working conditions are characterized by complex media (flammable, explosive, sulfur-containing, corrosive), wide pressure range, high continuous operation […]
What Size Air Dryer Do You Need? Matching Dryer Capacity to Your Compressor
Buy an air dryer that matches the compressor nameplate CFM and you should be fine. That is what many first-time buyers assume. Sometimes the assumption holds. More often, it leads to a dryer that is slightly undersized — still running, still removing some moisture, but not delivering the dew point it was specified to achieve. […]
Diaphragm Compressor vs Piston Compressor: Which Is Better for You? 2026 Selection Guide
In the industrial gas compression sector, diaphragm compressors and piston compressors are the two most widely used types, but they differ significantly in applicable scenarios and performance characteristics. The core of selection is not “which is better” but “which is more suitable for your actual needs” — every operational detail, from pressure requirements and gas […]
Why Is Oil-Free Compressed Air Critical for PCB Manufacturing and Electronics Assembly?
A single drop of oil in the wrong place can scrap an entire batch of printed circuit boards. It does not take much. The pneumatic systems that drive SMT pick-and-place machines, the air knives that dry boards after cleaning, and the actuators that move conveyors all use compressed air that comes into direct or indirect […]
