Description
Technical field
The utility model belongs to oil-gas pipeline pigging and detection field, and in particular to a kind of adjustable speed wiper and its rate controlling
Mechanism.
Background technology
According to statistics, Chinese pipeline mileage alreadys exceed 120,000 kilometers, wherein the conduit running time for having more than 30% is more than 10
Year, there is very big potential safety hazard.To ensure the normal operation of pipeline, it is necessary to periodically carry out pigging and detection operation to pipeline.
The purpose of pigging be clean pipeline in debris, hydrops, contamination, improve pipeline operation efficiency, reduce friction loss, when pigging with
Detection is carried out simultaneously when, pipe deforming can be also obtained, corroded, the data such as crackle are simultaneously accurately positioned to these defect of pipeline,
For the pipe-line maintenance in later stage provides authentic communication.At present, the wiper of main flow relies primarily on itself to pumped (conveying) medium in pipeline
The pressure difference that retardation is formed drives advance, but because the pressure of pipeline upstream and downstream has fluctuation, particularly builds up in recent years
Heavy caliber, high pressure, high flow rate long distance gas pipeline, velocity of medium alreadys exceed 5m/s, and spot speed is likely to be breached more than ten
Metre per second (m/s) so that the speed of service of working equipment is not sufficiently stable, the instantaneous speed of service can change between 0~25m/s.According to
SY/T 5922-2003《Natural gas line operations specification》8.7.4.1 item specifies that " the wiper speed of service is typically preferably controlled
3.5m/s~5m/s." when the pipeline operation equipment speed of service is more than 5m/s, it is undesirable signal acquisition easily occur, or even goes out
Now can't detect the phenomenon of signal, it is impossible to complete pipe detection task, What is more, because the internal detector speed of service is too fast,
The impact to pipeline and operational outfit is easily caused, the interests of serious accident, infringement user and enterprise are caused.Therefore adjust
The internal detector speed of service makes it operate within rational velocity interval, certainly will turn into and be carried in detection process in gas pipeline
Problem encountered when pipeline accuracy of detection high and reduction security incident risk.
The wiper of main flow adjustable speed is to realize control in real time by carrying the eduction valve of closed-loop control both at home and abroad at present
