Aforesaid ground heating pipes automatic detection machine is characterized in that also being provided with retaining valve 10 between described pneumatic stopping valve 9 and outfall sewer.
Aforesaid ground heating pipes automatic detection machine, it is characterized in that described control system adopts PLC to control, adopts pressure sensor is gathered pipeline pressure, and by the AD module of PLC the current pressure state is sent among the PLC, adopts touch-screen to show the state and the operation on each road.
The invention has the beneficial effects as follows: the present invention is integrated the checkout equipment of existing ground heating pipes, has improved automaticity, and is easy to use when making check, efficient is high, and effectively reduces production costs.Independent control: each road pipeline is separate, mutually noninterfere.Multistage water pump supercharging: under different needs, adopt different pumps that pipeline is suppressed, as earlier with pressure is little but the pump priming that flow is big, little with flow then but pump supercharging that pressure is big.Or the scheme of other similar fashion realizations.Aqueous vapor discharging: an end pressurized air is exerted pressure, and other end vacuum pump extracts and forms negative pressure, and water is temporary in the water tank, long-pending fullly by centrifugal pump water is discharged certain time the, or the function that realizes of other similar schemes.
Description of drawings
Fig. 1 is the principle of work synoptic diagram of ground heating pipes automatic detection machine of the present invention.
Embodiment
Below, in conjunction with the accompanying drawings to concrete being described below of the present invention:
Fig. 1 is the principle of work synoptic diagram of ground heating pipes automatic detection machine of the present invention.As shown in the figure, ground heating pipes automatic detection machine of the present invention mainly is made up of control section, water inlet 1, waterflood pump 2, supercharge pump 3, air source inlet 14, well heater 15, pneumatic four-position valve 6, tensimeter 7, pneumatic stopping valve 9, piping system and unwatering system.The moving four-position valve 6 of outlet stool ventilation of supercharge pump 3, waterflood pump 2 and air source inlet 14, clamping ground heating pipes 8 to be checked between pneumatic four-position valve 6 and the pneumatic stopping valve 9, tensimeter 7 is installed on the outlet of pneumatic four-position valve 6, the outlet pass-out supply mains of pneumatic stopping valve 9.Unwatering system comprises: water tank 11, back water pump 12 and vacuum pump 13.Outfall sewer joining water box 11 is provided with the logical vacuum pump 13 of pipeline on water tank 11, be provided with a level switch (not shown) in the bottom of water tank 11 apart from water tank 11 bottom certain distances, and level switch control back water pump 13 is through the outside draining of retaining valve.Between air source inlet 14 and pneumatic four-position valve 6, be provided with well heater 15, be used for gas is heated.
In when work, for each test pipeline, at first from water inlet 1 by waterflood pump 28 water fillings in ground heating pipes, when gas is discharged fully floor heating pipe material 8 in, start supercharge pump 3 beginning superchargings, when pressure arrival predetermined value and stop supercharging after a period of time of delaying time.Carry out ftercompction when institute's testing conduit starts in 3 pairs of ground heating pipes 8 of supercharge pump after expanding after a while once more, ftercompction begins the pressurize test after predetermined value.If in official hour pressure drop greater than a value after system make response, provide corresponding alarm.Vacuum pump 13 begins to bleed after detecting, and begins injecting compressed airs simultaneously in the ground heating pipes 8 to help draining.That is: an end pressurized air is exerted pressure, and other end vacuum pump extracts the formation negative pressure makes water to whose case flow, and water is temporary in the water tank.After exhausting, water begins to dry up residuary water in the ground heating pipes 8 with hot-air.Four effect positions of pneumatic four-position valve 6 are for selecting low-pressure water, water under high pressure, pressurized air or valve-off.
The purposes of water tank 11 and vacuum pump 13: in draining and when drying up, open the air that vacuum pump 13 extracts in the pipelines, form negative pressure, water in the pipeline or gas are drawn in the water tank 11.Establish a level switch in the water tank 11, ponding is discharged water in the water tank 11 to a certain degree opening back water pump 12 automatically, and the body or the water existence is arranged during with vacuum pump 13 of occurring bleeding when can avoid separately with back water pump 12 like this causes damage to equipment.Also can adopt similar scheme to realize.
On the pipeline of supercharge pump 3, also be provided with safety valve 4, the outlet of safety valve 4 mouth of a river 5 of running in.It is too high to be mainly used in the hydraulic pressure that prevents in the pressure piping, influences safety.When hydraulic pressure was too high, safety valve 4 was opened, and the water in the pipeline is discharged from freeing port 5, carried out step-down.
Also be provided with retaining valve 10 between pneumatic stopping valve 9 and outfall sewer, retaining valve 10 is used to prevent the aqueous vapor crossfire.
In this system, adopted multistage water pump supercharging, that is: under different needs, adopt different pumps that pipeline is suppressed, as earlier with pressure is little but the pump priming that flow is big, little with flow then but pump supercharging that pressure is big.Or the scheme of other similar fashion realizations.Therefore mutually noninterfere can be independently controlled on every road.As one the tunnel in water filling, the one tunnel is suppressing, and also has one the tunnel drying up, and special state occurring when having avoided carrying out simultaneously an operation need restart, and has improved work efficiency.
Control system adopts the high PLC of stability to control, and for directly perceived and be convenient to operate state and the operation of adopting touch-screen to show each road, adopts pressure sensor gathers pipeline pressure and the AD module by PLC is sent to the current pressure state among the PLC.
The foregoing description does not limit the present invention in any form, and all technical schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in protection scope of the present invention.
