Device is all disposed within shell, and industrial panel computer 3 is provided with the outside of shell, and the industrial panel computer 3 passes through data
Transmission line 11 is connected to calorimeter 2 and Temp. measuring ball valve 8.
The first stainless steel snap joint 7 is provided with the shell, the Temp. measuring ball valve 8 is quickly connect by the first stainless steel
First 7 are connected to the import of vertical underground pipe 12, and automatic exhaust steam valve 6 is provided with the import of vertical underground pipe 12.
The second stainless steel snap joint 17 is provided with the shell, the calorimeter 2 is quickly connect by the second stainless steel
First 17 are connected to the outlet of vertical underground pipe 12, the exit of vertical underground pipe 12 are provided with water filling bucket 10, in water filling bucket 10
And second be provided with y-type filter 9 between stainless steel snap joint 17.
Vertical underground pipe 12 is placed into the lower section of ground 11.
Tester body housing, which is used, uses 304 stainless steels, it is considered to which instruments weight problem, thickness uses 1.2mm
Stainless steel, intensity is met to carry and required, shell is assembled using pulling rivet, is difficult to open, and is conducive to protecting internal component.
Built-in calorimeter 2, while collecting temperature and heat, data are more accurate, direct, calorimeter is public using listing
Take charge of product, it is ensured that Product Precision quality requirement.The shell of internal heat 4 is made using stainless steel square pipe, and electric heater is adopted
Use high-quality heater.Canned motor pump 1 uses minisize shielding water pump, and power is small, while reducing thermal loss, reduces equipment operation
When noise.
The gathered data hardware of industrial panel computer 3 is directly transmitted with calorimeter, reduces transmission range, Stainless Steel Shell drop
Low influences of the extraneous various interference sources to data.
When engineering site is tested, equipment belt external connection water lines pipe fitting, using stainless steel snap joint+ripple
Pipe quick links, the convenient hot-melt adhesive paste with PE pipelines.
Different heating powers are selected according to the depth of different underground pipes.Instrument is heated using three gears, and every grade of power is
2KW, the method provided according to international earth source heat pump association, heating linear meter(lin.m.) power is 50--80w/m, and such as depth is 100 meters, plus
Thermal power is then 5-8KW, and 6KW can be used during test.
The peak power 210w of canned motor pump 1, using maximum power, meets turbulent under various underground pipe measurement conditions
It is required that.
Calorimeter 2 directly measures the specific calorie value applied to underground pipe, has abandoned by measuring voltage and electric current then
Calculating application heat causes to apply the inaccurate factor of heat Calculation.So that applying calorie value more directly, accurately.
System water filling uses outward appearance pipeline get water bucket water filling during test.Water filling bucket 10 and duct member use universal component, easily
In replacing.
Full automatic automatic exhaust steam valve 6 is mainly used to removal system internal gas.Using low water inlet, high exhaust mode.Easily
In system exhaust.
Operating procedure of the present utility model：
Levelling of the land, tester is put on smooth place.The plank preferably on the pad of tester bottom, height preferably from
Ground 200mm, prevents harm of the rainwater to equipment, builds tent, carry out flashing, wind proofing measure.Now check on tester body
Switch all in closed mode.
Power line is connected on the power line thrown away outside tester, tester power supply can select using 220V or
380V power supplys, are then wound with mackintosh.
Aviation plug is that outside welding PE is effective on tester body, and illumination during test is used, and draws power outlet
Obtain electric, fuse machine is inserted on socket, wait fuse machine to reach setting fusion temp.
External power source is delivered into total air switch inside tester, it is then that the air switch on tester body is upward
Push away, rotary switch is used for controlling the startup of water circulating pump to stop, clockwise turning to unlatching, rotate counterclockwise is closing.
By the snap joint pipe collar of equipment institute band and underground pipe hot-melt adhesive paste.
Bucket is wound into raw material band, is connected with equipment water filling port.Then system starts slow water filling.Checked in the injecting process
Whether leak source is had, if not provided, carrying out rubber and plastic insulation to exposed parts, blend compounds band is twined.
During water filling, when bucket does not have bubble, crawl water pump, it is found that bucket also has bubble and emerged continues crawl water pump,
Continue to be vented, the bubble in system is discharged.
After the completion of exhaust, continue ON cycle water pump, now " flow value " on tablet personal computer inside test interface this
Item should have numerical value, and otherwise explanation exhaust is not thorough.Then the initial temperature of start recording Rock And Soil, after 20 minutes, opens electricity
Heat
When measuring Rock And Soil initial temperature, it is necessary to ensure that flow has numerical value, and this numerical value changes in ruthless a small range,
Illustrate that system exhaust has no problem.Otherwise illustrate there be gas in water piping system, if gas, although water pump is in fortune
Turn, this same numerical value is zero, it is necessary to carry out bleeding again.
Instrument operation logic principle：1. first before outside main power source power transmission before, it is ensured that three 1P electrical heating switch, test
The total earth leakage circuit-breaker of instrument body is closed【It is closed mode downwards】2. and then main power source power transmission, close total electric leakage
Protection switch, now instrument still will not run.Now only aviation plug has electricity all the way, can now plug fuse machine, uses
Hot melt is connected with buried pipeline in connecting test instrument, night light fixture is connected.3. water lines connection is finished, and is opened from water-adding bucket
Beginning water filling, untill no bubble is produced, startup instrument water circulating pump rotary switch, instrument meeting automatic detection pipeline water temperature,
During less than 65 DEG C, water pump can just be operated.If higher than 65 DEG C, even if switch is in an ON state, water pump, electrical heating will not also be transported
OK.Whether the industrial panel computer data display 4. on observation instrument is normal.
After tester debugging is normal, photograph is carried out to on-the-spot test.Keep on file and be shown in ground thermal property survey
Examination.
Tester can cancel water tank completely by repeatedly testing in proof, test process, water tank is to cause volume mistake
Big main cause, using the water filling bucket in heating as system water filling port, small volume, and can be dismantled, selection of recycle water pump
It is excessive, it is also to cause the reason for tester body is excessive, by Multitest, accurately selects water circulating pump, abandoned multi gear
Flow is adjusted, unnecessary electric member and control system is reduced.
The utility model redesigns tester shell and inner structural members, and internals installation site, outside
Shell uses 304 stainless steels, is easy to protection equipment prototype part, and prevent the generation of iron rust.Internal pipeline part and instrument
Part uses stainless steel and copper material, prevents internal system pipeline from iron rust occur, in outside connecting line pipe fitting, increase filtering
Device, prevents internal system from entering impurity.
Device interior sets electric interlocking installation, is run by micro-computer temperature protector control system, prevents artificial behaviour
The various hazards of maloperation and initiation caused by making.
Data display and storage problem.The record of data and storage use the software using industrial configuration king as platform development,
Software is reliable and stable, and can be according to customer requirement sets itself time data memory interval problem.In device powers down, data are not
It can lose.
