Description
Technical field
The utility model relates to silt conveying technology field, is specifically related to a kind of long apart from slurry pipeline water attack, cavitation prevention and volume control device.
Background technology
For a long time, in waterpower silt is carried, the mode that adopts high pressure pump to carry is widely used.Concrete using method is with water blast gun, soil to be broken into mud in borrow areas, then with mud pump the slurry transportation producing in collection stock tank, then carry at a distance with force (forcing) pump.The moment starting at force (forcing) pump, owing to being full of water or mud in pipeline, so slurry pipeline approaches the soldered of force (forcing) pump one end and pipeline connection because the effect of water attack, cavitation erosion is often burst apart and damages, the series of problems such as force (forcing) pump compels to stop, pipeline dismounting, maintenance work have been caused, strengthen work capacity, greatly reduced again operating efficiency simultaneously; In addition, just in time with 1 force (forcing) pump of many mud pump is supporting, reach mud pit and enter slurry-outlet quantity balance, if stopped work or maintenance in short-term but there is 1～2 mud pump to damage, can cause that large pump and little pump delivery do not mate, large pump depletion, pipeline cavitation erosion, be forced to the problems such as termination of pumping, process these problems and also can greatly reduce operating efficiency.
Because the necessary electromotor using in current engineering does not have frequency conversion, Variable Velocity Condition mostly, can not control pipeline flow by adjusting rotary speed, in growing apart from slurry pipeline, on the midge pipelines that adopt at force (forcing) pump, flow-controlling gate is installed more and control the mud flow rate that enters force (forcing) pump.At many mud pump and a force (forcing) pump matching used time, in the situation that mud pump has 1～2 damage, can regulate the flow-controlling gate on midge pipeline, control mud flow rate, make mud pit turnover flow reach new balance, can avoid like this on pulp pipeline in valve closing the problems such as high pipeline connection damage, the soldered causing of voltage rise bursts apart; But the valve opening on pulp-absorbing pipe diminishes and can cause that pipeline cavitation erosion, lift reduce, inhale the problems such as sky, pipe vibration simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of long apart from slurry pipeline surge defence and volume control device.
In order to realize above object, the utility model adopts following technical scheme:
A kind of long apart from slurry pipeline water attack, cavitation prevention and volume control device, comprise slurry pipeline I, slurry pipeline II, midge pipeline and collection stock tank, integrate stock tank as open type collection stock tank, slurry pipeline I diameter is that φ 133mm, slurry pipeline II are that φ 300mm, midge pipeline are φ 300mm, described slurry pipeline I one end is connected with mud pump, the other end extends in collection stock tank, described midge pipeline one end is arranged at collection stock tank bottom, the other end is connected with 300BS force (forcing) pump, described force (forcing) pump is connected with slurry pipeline II, described midge pipeline stage casing is provided with a flow-controlling gate, described force (forcing) pump first segment grout outlet one side is provided with φ 150mm mud reflux line, described mud reflux line extends in collection stock tank, described mud reflux line is provided with mud recycle control valve, on described midge pipeline, midge flow-controlling gate right side is provided with 150mm slurry pipeline III, described midge pipeline is connected with mud reflux line by slurry pipeline III, described slurry pipeline III stage casing is provided with flow-compensated control cock, described flow-compensated control cock is manually to control cutter type flat gate valve.Mud recycle control valve on flow-controlling gate and the mud reflux line in described midge pipeline stage casing is manual control cutter type flat gate valve.
The length that the utility model provides is apart from slurry pipeline water attack, cavitation prevention and volume control device, on midge pipeline, midge flow-controlling gate right side arranges slurry pipeline III, midge pipeline is connected with mud reflux line by slurry pipeline III, and in slurry pipeline III stage casing, overfall flow compensation valve is set.Making like this reflux line is three-way pipeline, and one of them leads to collection stock tank with the bifurcated pipe of gate valve; Another bifurcated pipe with gate valve leads to midge compensation of pipeline slurries, and the cavitation erosion of midge pipeline, lift that the slurries deficiency sucking while solving midge pipeline gate valve closed portion causes reduce, inhale the problems such as sky, pipe vibration.When solving pulp Pipeline Water Hammer problem, overfall flow compensation valve is closed condition, by mud recycle control valve, opens and closes to remove water attack harm; When mud pit mud is not enough, midge flow-controlling gate is in part closed condition, for solving the problems such as pipeline cavitation erosion that pulp-absorbing pipe inhalation flow deficiency causes, vibrations, now can close mud recycle control valve, flow-compensated overfall control cock appropriateness is opened simultaneously, by backflow slurries, make up the problem of pulp-absorbing pipe inhalation flow deficiency, solve pulp-absorbing pipe cavitation erosion, lift reduction, inhale the problems such as sky, pipe vibration.
