Embodiment

[0039] Embodiment. This example is a test device and method, and the constitution of device is as figure 1 shown. It is to install a parallel temporary bypass pipeline 2 by connecting the temporary pipeline flange (2″) I 9 and connecting the temporary pipeline flange II (2″) 10 beside the main pipeline 1; when connecting the temporary pipeline flange In each pipeline between I 9 and connecting temporary pipeline flange II 10, install two main pipeline filter screens before installing two main pipeline filter screens on both sides of the flange with main pipeline filter screen 7 and bypass pipeline filter screen 8 respectively. Valve 3, manual valve behind the main line filter 4, manual valve in front of the side line filter 5, manual valve 6 behind the side line filter; that is, install the manual valve in front of the main line filter in sequence from the front of the main line 1 oil flow 3. The flange of the filter screen 7 of the main line, the manual valve 4 behind the fi...

Abstract

The invention discloses a method for performing circulating washing on lubricating oil of a natural gas large-scale compressor station by using a parallel pipeline, and relates to the technical field of lubrication and pipeline systems of variable capacity machines and common machines. A parallel pipeline structure is adopted by the washing method, a main pipeline filter screen front hand valve (3), a flange of a main pipeline filter net (7), and a main pipeline filter net rear hand valve (4) are sequentially arranged on the front part of a main pipeline (1) in an oil flowing direction; a side pipeline filter net front hand valve (5), a flange of a side pipeline filter net (8), and a side pipeline filter net rear handle valve (6) are arranged on the front part of a side pipeline (2) sequentially in an oil flowing direction; and the method comprises the following steps of: (1) installing a parallel pipeline and detecting the filter net; (2) washing oil of a system in a partitioned way; (3) performing circulating washing by using the parallel pipeline; and (4) recovering the pipeline. The method is short in washing duration, high in quality, small in lubricating oil loss, low in cost, high in efficiency, and easy to operate and control and slightly pollutes environment.

Description

technical field [0001] The invention relates to a method for circularly flushing lubricating oil parallel pipelines of a large natural gas compressor station. It relates to the technical fields of variable capacity machines, lubrication of general machines and pipeline systems. Background technique [0002] In the installation project of long-distance natural gas large-scale compressor stations, the oil flushing of the compressor lubricating oil pipeline is the most critical process in the installation process. important. In the past, series pipelines were usually used, and the compressor system pipeline and equipment were connected together for overall oil flushing. When the filter screen was replaced in this method, the oil flushing operation had to be stopped repeatedly, which not only caused high construction costs and serious waste of lubricating oil; The cleanliness of the pipelines and equipment is not high, and the construction period is long, which seriously affec...
