Description
Technical field
A kind of outer diameter tube measurement apparatus is the utility model is related to, particularly a kind of portable pipe of easy adjustable extent
Road diameter measuring device.
Background technology
To carry out《Notice of the State Council on printing and distributing water prevention and cure of pollution action plan》（Promulgated by the State Council [2015] 17）Will
Ask, as the thermal power generation corporations of highly water intensive industry, its water consumption accounts for 40% or so of the industrial total water consumption in the whole nation, and draining accounts for
The 10% of national industrial enterprise's discharge capacity, new situation and challenge are faced with section water and wastewater treatment disposal.Each electricity power group
All carrying out the investigation of water resources comprehensive utilization present situation, each electricity power enterprise carries out the full factory's water balance experiment in our factory one after another, and test is originally
The taking of factory, use, row, water consumption water simultaneously evaluate water using level.The number of tubes of thermal power generation corporations is numerous, and pipe diameter size is not
One, pipe arrangement have it is horizontally disposed, be arranged vertically, arrangement height is most of to wait many factors between 0-2.5 rice, to scene
Test brings higher difficulty.
According to DL/T 606.5-2009《The part of thermal power plant energy balance directive/guide the 5th：Water balance is tested》Middle water is auxiliary
Auxiliary measuring method：Ultrasonic wave tube method, ultrasonic wave open channel method, current meter method, volumetric method etc..According to the actual feelings of power plant water
Condition, water intaking, pipeline is used with water, draining, conveyed outside individual power plants waste plant using open channel, therefore in full factory's water balance
Test of the experiment process to water uses ultrasonic wave tube method.The key instrument that ultrasonic wave tube method uses is ultrasonic flow
Meter, need to be outer diameter tube before using ultrasonic flow rate measurement examination（It is accurate to 1mm）, the parameter input such as wall thickness and material
The transmitter of ultrasonic flowmeter, the distance between sensor installation test point is calculated, finally determines on pipeline at 2 points
Specific test position.One key factor of accuracy of flow rate test is the position of two measuring points, and the calculating of both sides point position is
By the measurement of pipe diameter, then the position of both sides point is calculated, therefore the accuracy of pipe diameter measurement determines that flow is surveyed
The accuracy of amount.
At present in the full factory's water balance test in thermal power plant, outer diameter tube measuring method mainly has two kinds：1. it is that steel is straight
Chi or steel tape, both ends are aimed at eyes, and outer diameter tube is drawn further according to experience；2. with tape measuring girth, divided by 3.14
External diameter is calculated, then data are accepted or rejected.Method is 1. very big for firm registration or the employee to lack experience, error；Method
2. in actual calculating process, often occur that some decimal digits are many or aliquant phenomenon, last external diameter is at data
Numerical value after reason；And in girth test process, test and comparison trouble, the inconvenience of big pipeline girth.According to above-mentioned measurement
The external diameter that outer routing method is tried to achieve, input in the transmitter of ultrasonic flowmeter, the point position calculated, go out in test process
Now row phenomenon：It is larger that 1. data deviation occurs in test flow（Compared with the average flow in certain time）；2. sometimes two
Probe does not receive signal, fixes a probe positions, another probe positions is moved to the left or to the right, with regard to that can receive letter
Number.
Device on measuring diameter has a lot, respectively there is advantage and disadvantage.Such as slide measure, measurement accuracy is very high but surveys
Measure within scope Ф 300mm；Chinese patent " double light path laser large diameter measurement instrument, a kind of portable big diameter apparatus and its survey
Measure parameter calibration method ", it is applied to precisely test in laboratory using laser scanning or displacement transducer；
At present, large-scale round part（Such as large-scale cast tube, seamless steel pipe, concrete duct bell and spigot steel loop）In the measurements, generally
It is to use large-scale thousand points of bars, selects some test points in tested bore, measure diameter value, find out the difference of maxima and minima,
The as deviation from circular from of the pipe.This method measurement efficiency is low, and it is interruption that it, which is measured, discontinuous, it is difficult to find the maximum of caliber accurately
Value and minimum value, so the low precision of measurement is just can hardly be avoided, measurement efficiency is low.
Chinese patent 201610660161.2 discloses cable diameter gauge inside and outside a kind of pipe, including three rollers, two surveys
Amount arm and angular displacement sensor, two measuring arms are rotatably connected, and junction sets one of roller, two measuring arms
Outer end respectively sets another roller, and roller is fixed in measuring arm by wheel shaft, and can be rolled, the wheel shaft of two measuring arms
Spacing between hole is equal.The program is applied to work high above the ground, singlehanded operation, the major diameter pipe internal-and external diameter of place restricted area
Measurement, it is impossible to solve that thermal power plant pipeline is more and outside diameter measuring that miscellaneous, pipe diameter size differs.
