Abstract
The invention provides an intermediate relay booster pump station, and belongs to the technical field of pipeline liquid delivery. The intermediate relay booster pump station is used for pressurization of liquid in the pipeline liquid delivery process. The intermediate relay booster pump station comprises a ball valve which is arranged on a liquid delivery pipeline between a liquid inlet and a liquid outlet. A first gate valve, a filter, an electromagnetic flow meter, a centrifugal pump, a first one-way valve and a second gate valve are sequentially arranged on a pressurization pipeline in parallel connection with the liquid delivery pipeline where the ball valve is located, the centrifugal pump is connected with a diesel engine, a second one-way valve and a third gate valve are sequentially arranged on a station cross pipeline in parallel connection with the liquid delivery pipeline where the ball valve is located, and an oil discharge port is connected to the pressurization pipeline between the first one-way valve and the centrifugal pump. The intermediate relay booster pump station mainly has the three functions of intermediate pump station pressurization relay, automatic station crossing and pipeline cleaning (can serve as a bypass). A pipe cleaning device can clean a pipeline system through an intermediate pump station. The intermediate pump station is provided with the station crossing bypass, so that the condition that an inlet pipeline is blocked can be effectively prevented.
Description
Technical field
The invention belongs to pipeline liquid conveying technology field.Be specifically related to a kind of containing pipeline cleaning, the middle relay pumping plant of automatic overreach function, is mainly used in the supercharging relay in pipeline liquid course of conveying, thus realizes the long-distance sand transport of liquid.And there is the increase pumping plant of the automatic overreach function of pigging.
Background technique
At present, domestic for the pressurized pump station in pipeline liquid conveying, mostly adopt the direct supercharging of inlet/outlet, an additional bypass door.Its deficiency: one is if will clear up pipeline system, pump station part is often needed to remove, reconnect pipeline to realize, or adopt and often run into pumping plant and just remake and once clear up, such pipeline system divides multistage cleaning, not only inefficiency, and inevitably cause fluid seepage; Two is that pumping plant in use lacks automatic overreach function, and in using process, because various uncertain factor may make pumping plant stop, causing inlet ductwork to suppress extremely, pressure increase, causes pipeline burst.
Summary of the invention
The object of the invention is to overcome the above-mentioned deficiency of prior art and a kind of middle relay pressurizing pumping plant with pipeline cleaning, automatically overreach function is provided.
Technological scheme of the present invention is: comprise the ball valve on the liquid transport pipeline that is arranged between liquid entering hole, liquid outlet; The pressure pipeline in parallel with indusion tube section, ball valve place is provided with successively the first gate valve, filter, flowmeter, centrifugal pump, the first one-way valve, the second gate valve; Described centrifugal pump is connected with motor; The overreach pipeline in parallel with indusion tube section, ball valve place is provided with successively the second one-way valve, the 3rd gate valve; Pressure pipeline between described first one-way valve and centrifugal pump is connected with a fuel outlet.
Described flow counts electromagnetic flowmeter.
Described motor is diesel engine.
Described liquid entering hole is connected with inserting turning joint.
Described liquid outlet is connected with inserting turning joint.
The present invention mainly contains intermediate pump station supercharging relay, automatically overreach and pipeline cleaning (can serve as bypass to use) three zones.Wiper, by intermediate pump station, can realize the cleaning of whole system pipeline under the condition of not removing this pumping plant; Intermediate pump station carries overreach bypass, can effectively prevent in infusion process, and this pumping plant major loop blocks, and line pressure raises, and causes pipe explosion accident.
Accompanying drawing explanation
Fig. 1 is schematic circuit of the present invention.
Fig. 2 is structural drawing of the present invention.
Fig. 3 is pipeline connecting figure of the present invention.
In figure, 1, flowmeter, 2, filter, the 3, first gate valve, 4, liquid entering hole, the 5, second one-way valve, 6, ball valve, the 7, the 3rd gate valve, 8, liquid outlet, the 9, second gate valve, the 10, first one-way valve, 11, motor, 12, centrifugal pump.
Embodiment
When pressurized pump station of the present invention uses, there are three kinds of operating modes respectively.
Note: before often kind of operating mode uses, all valves are all in closed condition, illustrate no longer separately below.
1, circuit cleaning
Pumping plant inlet/outlet forms straight line, and flow process walks liquid entering hole 4, ball valve 6, liquid outlet 8, ball valve 6 standard-sized sheet, and foreign material and wiper can be made in pipeline scale removal process freely to pass through.
2, automatic overreach
Pumping plant carries overreach bypass, and flow process walks liquid entering hole 4, the second one-way valve the 5, three gate valve 7 standard-sized sheet, liquid outlet 8, when pumping plant because burst accident is suppressed extremely, inlet pressure is higher than outlet pressure, when pressure rises to one-way valve 5 cracking pressure settings, the second one-way valve 5 is opened automatically, realizes automatic overreach function.
3, pumping plant supercharging
Pumping plant normal supercharging is infused, and flow process walks liquid entering hole 4, the first gate valve 3, filter 2, flowmeter 1, centrifugal pump 12, the first one-way valve 10, second gate valve 9, liquid outlet 8; Wherein: the first gate valve 3, second gate valve 9 is opened, and liquid exports through pumping plant supercharging.Centrifugal pump 12 is connected with motor 11.
