Abstract

The invention discloses a pouring method of a natural gas power cylinder body, which aims to solve the problems of poor feeding property and more casting defects of a casting piece produced by an existing pouring method. According to the pouring method, the pouring temperature ranges from 1330 DEG C to 1350 DEG C. The pouring method is beneficial to feeding of a casting piece and can reduce other casting defects.

Description

technical field [0001] The invention belongs to the technical field of natural gas power cylinders, and in particular relates to a pouring method for natural gas power cylinders. Background technique [0002] In the prior art, natural gas is mainly compressed by a pipeline release steam turbine and a centrifugal natural gas compressor. [0003] At present, domestic and foreign natural gas compressors are mainly divided into high-speed and high-power reciprocating piston compressors and low-speed reciprocating compressors. Among them, the high-speed and high-power reciprocating piston compressor, with a speed n of 1000r / min and a power P of 6000kW, is mainly used for natural gas gathering and transportation pressurization and gas injection in gas storage. It is an indispensable equipment for natural gas exploration, development and storage . The power cylinder is the main part of the natural gas compressor to provide power during the process of compressing natural gas. The ...
