Oil-Free High Quality Piston Natural Gas Compressor LPG Compressor for Industrial Wholesaler

The Oil-Free High Quality Piston Natural Gas Compressor LPG Compressor is a reliable and efficient compressor designed for industrial use. It is manufactured with piston reciprocating motion technology, ensuring superior gas pressurization and delivery. The compressor consists of working chambers, transmission parts, body, and auxiliary components.

Product Description

The Oil-Free High Quality Piston Natural Gas Compressor LPG Compressor is specifically designed to compress gas and deliver it with precision. It is widely used in industries such as gas, chemical, and energy. The compressor is a key equipment in these industries due to its stable operation, long service life, and convenience in maintenance.

Key Features:

  • Low rotating speed
  • High component strength
  • Stable operation
  • Long service life
  • Convenient maintenance

The compressor is composed of various components, including a gas-liquid separator, filter, two-position four-way valve, safety valve, check valve, explosion-proof motor, and base. It is designed to have a small size, light weight, low noise, good sealing, easy installation, and simple operation. These features make it a reliable and efficient choice for industrial applications.

Piston Compressor

The piston compressor is a type of compressor that utilizes piston reciprocating motion to compress and deliver gas. It consists of a working chamber, transmission parts, body, and auxiliary components. The working chamber directly compresses the gas, while the piston, driven by the piston rod, undergoes reciprocating motion. This reciprocating motion alternately changes the volume of the working chamber, resulting in gas compression and delivery. The compressor effectively controls the pressure of the gas through valves that regulate the gas flow.

Liquid Delivery:
At the beginning of the liquid delivery process, the liquid phase pipeline between the tanker and the storage tank is opened. If the liquid level in the tanker is higher than the storage tank, the liquid automatically flows into the storage tank until a balance is reached. If the liquid phase in the tanker is lower than the storage tank, the compressor is started, and the four-way valve is in the positive position. The gas is extracted from the storage tank and discharged into the tanker. This process increases the pressure in the tank car and decreases the pressure in the storage tank, allowing the liquid in the tank car to flow into the storage tank.

Surplus Liquid Recovery:
The surplus liquid recovery process is the reverse of the liquid delivery process. After the liquid has been delivered, the four-way valve should be reversed, and the dotted line in the figure should be closed. At this point, the compressor inhales the remaining gas in the tanker, pressurizes it, and then discharges it into the storage tank until the pressure of the remaining gas drops to a value that no longer requires recovery. During the recycling process, it is vital to ensure that the compressor pressure ratio and exhaust temperature remain within allowable limits.
