China Standard Oil Free Liquefied Gas Compressor for Tank Car Unloading and Loading 491 LPG Compressor air compressor lowes

Product Description

The China Standard Oil Free Liquefied Gas Compressor is a high-quality and reliable compressor designed for efficient tank car unloading and loading. With its low rotating speed, high component strength, and stable operation, this compressor offers a long service life and easy maintenance. It is an essential piece of equipment in the gas, chemical, energy, and other industries.

Piston Compressor

The piston compressor is a type of reciprocating compressor that uses piston 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 compression process changes the volume of the working chamber, resulting in the pressurization and delivery of gas.

Compressor for Unloading and Loading

The ZW series of oil-free compressors is one of our flagship products. It is specifically designed for unloading, loading, dumping, residual gas recovery, and residual liquid recovery of LPG/C4, propylene, and liquid ammonia. This compressor features a compact size, lightweight construction, low noise operation, good sealing, easy installation, and simple operation. It is equipped with essential components such as a compressor, gas-liquid separator, filter, two-position four-way valve, safety valve, check valve, explosion-proof motor, and base.

During the unloading process, the compressor pressurizes the gas from the storage tank and transfers it to the tanker through the gas phase line. Simultaneously, it uses the pressure difference of the gas phase to move the liquid from the tanker to the storage tank. The loading process follows the reverse operation. It is important to note that when unloading, cooling of the gas phase is not necessary as it may prolong the process. However, for residual gas recovery, a cooler can be used to expedite the recovery process.
