Product Description

LPG Compressor

Working principle

This series of oil-free lubrication compressor is one of the first products produced by our factory in China. The product has low rotational speed, high strength of components and is characterized by smooth operation, long service life and easy maintenance. Among them, ZW series compressor is in the form of unit. It integrates compressor, gas-liquid separator, filter, two-position four-way valve, safety valve, check valve, explosion-proof motor and chassis. It is characterized by small volume, light weight, low noise, good sealing, easy installation and easy operation.

The product is mainly used for unloading, loading, dumping, residual gas recovery and residual liquid recovery of liquefied petroleum gas/carbon 4, propylene and liquid ammonia. It is widely used in gas, chemical, energy and other industries, and is the key equipment for gas, chemical, energy and other industries.

Note: In the process of unloading, the compressor pressurizes the gas from the storage tank and then presses it into the tanker through the gas-phase pipeline, and presses the liquid from the tanker to the storage tank through the pressure difference of the gas-phase in order to complete the unloading process. When the gas phase is pressurized, the temperature of the gas phase will rise, and at this time there is no need for forced cooling, because if the gas phase is compressed and then cooled, it is easy to liquefy, and it is difficult to build up the differential pressure of the gas phase, which is not conducive to the replacement of the gas phase with the liquid phase, in short, it will cause the unloading process to be prolonged. If residual gas recovery is required, during the residual gas recovery operation, a cooler can be selected to forcefully cool the gas phase so that the residual gas can be recovered as soon as possible.

The loading process is the opposite of the unloading process.
