Description
Technical field
This utility model relates to a kind of laboratory pipeline coal slurry and runs time register less than critical flow velocity, can extensively answer
For the experimental stage of coal slurry conveyed in pipeline engineering project, belong to coal slurry conveyed in pipeline index determining equipment technical field.
Background technology
For long-distance slurry pipe-line transportation system, during normal conveying, require that transportation flow speed ratio critical flow velocity is big, but long
It is the most rugged and rough that distance coal slurry pipeline lays landform, when running less than critical flow velocity, in conduit slope change position greatly,
Grain easily deposition, causes line clogging.Therefore, decision conduit running safety is also become less than the critical flow velocity operation time
One of key index.
Before this utility model is made, the laboratory pipeline coal slurry of coal slurry conveyed in pipeline runs the time less than critical flow velocity and surveys
Surely being the organic clear glass pipeline section by being arranged on coal slurry pipeline, manual observation surveying record coal slurry is in the duct less than facing
The time that boundary's flow velocity runs, as the reference frame of pipeline coal slurry transfer designs.This method automaticity is low, glass pipeline section
The transparency is poor, is difficult to differentiate, it is impossible to guarantee the accuracy of observed data in the case of coal slurry operation later stage speed is extremely slow.
Summary of the invention
Run the problems referred to above of timing in order to solve laboratory pipeline coal slurry less than critical flow velocity, improve test automatically
Change degree, reduces the error of manual observation timing, and a kind of laboratory pipeline coal slurry of invention runs timing less than critical flow velocity
Device, this plant automation degree is high, simple to operate, and accuracy is high.
This utility model takes techniques below scheme: this utility model relates to a kind of laboratory pipeline coal slurry less than critical flow
Speed runs time register, and it includes the variable-frequency control pump being arranged on coal slurry pipeline, fixing base, sealing device, data
Line, holes probe, control device；With controlling switch on variable-frequency control pump；Fixing base is arranged on coal slurry pipeline, according to work
Condition can vertically, horizontally or diagonally install be sealed by sealing device；Controlling device and be provided with controller, flow velocity display, timing shows
Show device, be arranged on fixing base；Control device and connected control switch and the holes probe of variable-frequency control pump by data wire, survey
Speed probe gos deep into detecting in coal slurry pipeline flow velocity.
Laboratory simulation complexity landform coal slurry pipeline, by variable-frequency control pump, variable concentrations and granular-grade in regulation pipeline
The coal slurry joined, when flow velocity display shows predetermined critical flow velocity, controller automatic imitation has a power failure or malfunction, closes
The control switch of variable-frequency control pump, starts timing display simultaneously and starts timing, and pipeline coal slurry runs until flow velocity display shows
Being shown as zero, be blocked state, timing display stops timing, and laboratory technician directly reads the data on time set.
The beneficial effects of the utility model are, may be used for, in any pipeline coal slurry conveying project, being less than as laboratory
Critical flow velocity runs timing and uses, and the design for pipeline coal slurry conveying project provides reference frame, it is achieved that self-clocking,
Decrease the error of manual observation timing, improve the accuracy of data.
