Problems solved by technology

Although the indicator can be displayed on site, it can also be remotely transmitted to the on-duty dispatching room, but the indicator is directly installed on the pipeline, which is troublesome to install and prone to failure, and the remote transmission can only transmit a simple switch signal, and must be on duty When people look at the meter with the switch signal, it is obvious that this technology has fallen behind

Abstract

An indication instrument for the pipeline cleaner is composed of two trigger switches, input coupling circuit, time calibrater, event inquiring circuit, control unit, clock display, alarm circuit, output circuit and power supply.

Description

technical field [0001] The invention is an indicating instrument for a pipeline pig entering and exiting a station. The invention relates to the technical field of signaling equipment and pipeline systems. Background technique [0002] In order to remove sediments, wax deposits, scales, etc. in the fluid pipeline, so that the pipeline can run efficiently, it is generally necessary to regularly pig the fluid pipeline. For example, due to the problem of wax deposition in crude oil pipelines, regular pigging is required, otherwise, not only will the efficiency of operation be affected, but in severe cases, blockages will be caused, which will affect the safe production of pipelines. The pipeline pigs currently in use are generally equipped with signal emission and ground tracking equipment on the pigs to track the pigs during the pigging process and determine their positions at any time. However, the exact time of the pig's departure from the station and entry into the statio...
