Description

High-efficient intelligent air compressor machine detection auxiliary assembly that leaks

Technical Field

The invention relates to the field of pipeline maintenance, in particular to a high-efficiency intelligent air compressor water leakage detection auxiliary device.

Background

The air compressor is a common auxiliary device in the pipeline leakage detection, the air compressor is small enough to be indoor and large enough to be outdoor, when a certain amount of air pressure is injected into a detected pipeline, air can be leaked from a pipeline leakage point, sound can be generated while the air is leaked, the audio leakage instrument can receive the sound frequency and convert the sound frequency into a visual signal and the sound generated by an earphone and a microphone of the audio leakage instrument is transmitted to ears, a master can judge and analyze the specific position of the water leakage point through the sound and the visual signal, two air compressors are commonly used in the current leakage detection industry, the air compressor for the first woodworking has large volume, is slow in air intake and has medium noise, and the pressure can only reach 8 kilograms; the second silent air compressor, namely the refrigerator compressor, has a low air charging speed, and the refrigerating oil in the machine enters a water pipe along with air and is harmful to health, has a slightly large volume and heavy mass, and has the most important defect that the air charging efficiency is low, although the silent pump can be used for charging 20 kg of pressure by arbitrary automatic circulation in a pressure interval, 8-10 kg of pressure is enough by general detection. The micro leakage of the new pipeline is detected to be not more than 17 kilograms of pressure at most. Especially, the high pressure of old pipelines is easy to be damaged, and the maximum of the old pipelines is generally not more than 10 kilograms. Sometimes the branch pipeline is more when detecting ground heating, and the house that the area is bigger of the villa that has many pipelines in the family, the more heating installation of water storage volume needs a great deal of air at this moment to carry out the evacuation, like the air pump of carpenter's usefulness and the slow silence pump of last gas just not very good use, the air pump of carpenter's usefulness still says that the gas holder can store air, open the valve can reach a large amount of air in the twinkling of an eye, wash the water in the water pipe clean in the twinkling of an eye, but be full of the gas holder time consuming in time. The mute pump is difficult to drain completely, and a master can better detect small leakage and micro leakage when checking that an indoor pipeline leaks water, the water drainage in a water pipe is more clean and more beneficial to detection and positioning, because the water pressure is smaller than a signal generated by air pressure when passing through a water leakage point, particularly, the water leakage point is just buried deeper below the pipe, the indoor pipeline is generally buried 6-15 cm deep, the wall pipeline is 2-5 cm deep, if the water leakage point is just caught at the lowest point of the whole water pipe, the water which is not drained completely can be stored at the water leakage point at the lowest point, and the reason why a large amount of air is needed to drain the water completely is the reason. The dual-purpose pump has the advantages of being poor in using effect, capable of being used for trial use after a period of time, and capable of being inflated into a DC660 model by iron with high inflating speed, and being lighter and lighter than the two pumps. The most important advantage is that the pumping speed is high, but the disadvantage is that the noise is larger, but compared with the above two pumps, the air compressor can only leave the factory for reciprocating circulation under the pressure of 3-6 to 9 kilograms before being improved. Can not the arbitrary pressure interval circulation of manual control, take off external manometer after the pressure sensor afterwards, master can control arbitrary manual circulation of the artificial switch pump of the pressure interval of wanting according to the manometer reading 0-17 kg pressure, must 2 master cooperations operate one to see pump one like this and use leak hunting appearance location leak water point, but manual control pressure is very unstable, can lead to the pressure to neglect the height and cause leak hunting appearance signal unstability, the fixed point success rate can reduce, pound poor brick probability and can increase, because there are 1 department or 2 departments or even many suspicious leak water points in the testing process, master can carry out the comparison signal value size to these several suspicious points respectively under the same pressure and analyze and conclude which is true which is false leak water point.

The invention has the beneficial effects that:

the invention comprises an air pump body, a digital display pressure controller for controlling air pressure and a remote control receiver are arranged on the air pump body, the remote control receiver is equivalent to a passive output switch of a pressure gauge, even if the pressure gauge works and the remote control receiver is disconnected, the pump stops, but the pressure gauge stops working and the remote control receiver is not closed, only the pressure digital display controller and the remote control receiver work simultaneously, the pump can cycle according to a set pressure interval value, when the power supply is switched on, the remote control receiver is disconnected, and only the remote control receiver is pressed to turn on a button pump to cycle according to the digital display pressure interval value, so that the two are safer to work together, the two work is lack of one and cannot be matched, a relay for controlling a circuit of the digital display pressure controller and a remote control receiver for remotely controlling the start and stop of the air pump body are arranged, 3 through pipes are communicated on an air outlet pipe of the air pump body, and the three-through pipes are respectively communicated with a pressure sensor probe and a second air pipe, the pressure sensor probe is communicated with the air inlet pipe of the digital display pressure controller, and the free end of the second air delivery pipe is communicated with the pipeline to be detected. Can remote control air pump open stop through the remote control receiver, save the manual work, improve work efficiency, be fit for extensively promoting.

In addition, the invention improves the automatic control circulation of any pressure interval, greatly improves the accuracy, because the pump stops starting at the lowest point when the value of the pressure interval is the highest point, the highest pressure is the same every time no matter how many times the pump circulates and the pump stops each time under the same pressure interval value, the lowest pressure value is the same every time when the pump starts each time, the same pressure value can be circulated for many times to compare suspected water leakage points, the internal pressure of the pipeline can be reduced by pressure relief through the leakage points along with the time during the circulation, a master roughly remembers the time interval between the pump start and the pump stop and then compares the pressure value from high to low at any time to compare similar leakage points, and the signal size and the sound of the pressure value at any time judge and analyze true and false leakage points. The pump can stop using the leak detector when the pump is started and can stop using the leak detector when the pump is stopped and has no noise. Or an additional air storage tank is additionally arranged for carrying out constant pressure, the number of start-stop times is reduced, more time is added for the use of the leak detector, of course, some teachers use the leak detector with abundant experience, which signal is noise can be analyzed, and a little pump noise exists at a point far from a measured point of a pump, the problem that the pump noise is not so called exists is solved. If the master uses the leak detector to determine that a position is not determined to be a true signal or a false signal similar to the true signal, the pressure in the pipeline is only leaked out to measure whether the signal exists or not by using the leak detector. If the pipeline is not pressurized at this time, but the leak detector displays a signal, the signal is a false signal, and the false signal is not too much when encountered in the detection process, and if the false signal is considered to be analyzed carefully. This method is called a method of elimination, and the pump is stopped when the method of elimination is performed, and sometimes, the elimination may be performed for a plurality of times, so that it is troublesome to go to the pump and stop the pump. If the pressure in the water pipe is preferably released when the water leakage point is positioned for excavation, the pressure in the pipeline is released before excavation because the water pipe may be collided and exploded when the electric pick is used for drilling bricks under pressure, and the pump is started again after the water pipe is seen after excavation to verify the position of the water leakage point. After a water leakage point is seen, pressure is released, then the position of the water leakage point is cut off by a pipe cutter for re-melting, if water which is not completely drained in the water pipe flows out of the cut-off position when the water leakage point is removed and repaired, a pump is started again, water in the water pipe is flushed by air pressure from the cut-off position, and no water can be melted in the water pipe. The water is washed clean by blocking the water pipe by a finger to start the pump, reaching a certain pressure and releasing the finger to go back and forth for several times, if one person goes back and forth to a place where the pump is started and stopped and then returns to a place where the water leakage is repaired, the person is very troublesome, and after the remote control is additionally arranged, a plurality of unnecessary operations are saved by only pressing the remote controller.

Be provided with digital display pressure controller 2, be used for control that are used for controlling gas pressure on the air pump body 1 the relay 3 of digital display pressure controller 2 circuit and be used for remote control air pump body 1 to open the remote control receiver 4 who stops, be provided with on the remote control receiver 4 and can fold antenna 5, the intercommunication has tee bend 7 on the 1 outlet duct 6 of air pump body, and 6 free ends of outlet duct are provided with auto-lock quick-operation joint female 14, and the intercommunication has relief valve 8 on the outlet duct 6, installs on the relief valve 8 and presses pressurization handle 16 with the hand of beating the high pressure usefulness. A check valve 15 is communicated between the air outlet pipe 6 and the tee joint 7, and a manual valve 71 is further arranged on a pipeline communicated with the air outlet pipe 6 of the tee joint 7. The tee joint 7 is respectively communicated with a pressure sensor probe 11 and a second gas pipe 12, the pressure sensor probe 11 is communicated with a gas inlet pipe of the digital display pressure controller 2, and the free end of the second gas pipe 12 is communicated with a pipeline to be detected. The front wall of the air pump body 1 is also provided with a remote control electromagnetic valve, a remote pulse automatic control electromagnetic valve change-over switch 17, a remote leakage detection automatic pressure compensation and manual pressure compensation switch 18 and a 24V normally closed electromagnetic valve external socket 19. An air inlet of the air storage tank 9 is communicated with the second air pipe 12, an air outlet of the air storage tank is communicated with a third air pipe 13, the free end of the third air pipe 13 is communicated with a pipeline to be detected, and an electromagnetic valve 10 for controlling the third air pipe 13 to be normally closed is arranged on the third air pipe 13. The model of the relay 3 is JZX-22f (d), the remote control receiver 4 is a learning digital wireless remote control switch, and it should be noted that the improved components used in the present invention are all the prior art, and the circuit connection of each component is well known to those skilled in the art, and will not be described herein again.

Referring to fig. 1, 2, 4 and 5, in a first use method, the free end of a second gas pipe 12 of the inventor is communicated with a pipeline to be detected, a pressure interval is set through a digital display pressure controller 2 for drainage detection, the method is portable and quick to install in a common detection room, and a large water leakage point can be searched for by the method. The method for prolonging the air pipe and the power line comprises the steps that a pump is placed outside a door or in a corridor, the continuous and stable pressure supply is far away from noise, a leak detector can be used for checking large leak points all the time, the method is practical, if the pump is placed in a corridor of 4 th or 3 rd stairs in 5 th detection, the noise is generally prolonged by 15 meters, the influence is hardly caused, if the noise is sensed by a prolonging method and is still large, the working noise of the pump in a slow gear position is reduced by half, but the method needs to be noticed when in use, the tail end of the air pipe is firstly connected with a place such as a kitchen angle valve position when in detection, and after the whole room is detected once, the tail end of the air pipe is changed into a place with a longer distance, such as a toilet is detected once in the whole room. When the angle valve is detected, the air pipe is preferably directly connected with the internal teeth by using a counter screw to remove the angle valve or the water tap, and because a large amount of air enters the pipeline from the angle valve after the air inlet is connected with the angle valve, the air and a narrow ceramic switch sheet in the angle valve generate sound similar to a signal due to friction, the angle valve is removed from direct connection. The far position detection is used for eliminating false signals generated by friction between air and pipe fittings, the false signals are generated when a large amount of air at the tail end of the extension air pipe enters the inner teeth and is collided, but the signals generated by large leakage points are much weaker, and then the signals before the far position detection are changed to eliminate true leakage or false leakage, which is also called a transposition elimination method.

Referring to fig. 1, 2, 3, 6 and 7, the second method is that a control electromagnetic valve is preferably additionally arranged on a short, medium and high-quality water leakage point or a pipeline, the method can prolong the pump starting time interval by stabilizing air pressure for the short water pipe, obviously reduces the digital display pressure value of the slightly leaked water leakage point of the short pipeline, stores more air after the tank is added, and does not obviously reduce the digital display pressure value of the slightly leaked water leakage point, so that the pump can not be frequently started, and the use of the leak detector can be stopped as soon as the pump rings to be closer to a detection place. The method for controlling the electromagnetic valve can not lead air in the tank to be wasted and leaked out from a large leakage point when the pump stops using the leak listening instrument, and a master can find the large leakage point by controlling the electromagnetic valve to be opened and closed to be matched with the leak listening instrument. To the pipeline more install the gas holder additional can open the water gas storage tank in the pipeline more clean of discharging in the twinkling of an eye, control solenoid valve with the gas holder method can also be better the water clean of discharging in the pipeline, be favorable to detecting, can also save and avoid leaking the air of gas holder when judging to get rid of, because close the solenoid valve when judging whether be true false signal, open the tap and let out the air in the pipeline, the solenoid valve is closed and is kept the air in the gas holder, for detect once more and fill pressure in the pipeline, the time of having reduced pump work has improved work efficiency. Secondly, this method is a very rational way of detection and the first is that carrying the can and assembling are laborious. But most indoor detection all need not the canning, only the canning under the special condition, and jar body and solenoid valve are integrative, and host pump and jar body can be swiftly assembled by the nimble dismantlement. The pot adding method can be connected with a nailing gun for woodworkers and can be used as an air pump for woodworkers.

Referring to fig. 1, 2, 3, 7 and 8, in the third method, a pulse method is used for detecting a large water leakage point, generally a broken pipe or a pipe wall with a large crack, for example, a frost-cracked pipe, the water leakage point is too large, and a large amount of gas does not leak from the crack under the working pressure of a pump, the pulse method is used for detecting the water leakage point, when the pressure of a gas storage tank reaches a set highest point, the gas pressure in the tank is released from the crack at the moment that a pump stops working, an electromagnetic valve is opened, a large signal is generated at the water leakage point, if the signal is obvious, a human ear can hear the signal, the working principle and the wiring mode are that the normally closed electromagnetic valve and the pump are simultaneously connected with an output end of an electrical relay, so that the pump and the normally closed electromagnetic valve work alternately to realize pulse gas pressure, and the water leakage point is automatically and circularly inflated and deflated to find the water leakage point.

Referring to fig. 1, 2, 9 and 10, the fourth method, the high pressure test method, the change-over switch is changed into manual on and off, the high pressure method can be used when some iron pipes or micro leaks are searched, the pressure release valve 8 is pressed by hand, if the pressure is not pressed, the pressure release valve 8 automatically opens and reduces the pressure when the pressure reaches 12-13 kg, and the maximum pressure can be reached by pressing the pressure release valve 8 at the moment 16-17 kg.

As shown in fig. 11, a fifth method, a multiple pump-in-one method, fire fighting in outdoor pipeline districts, pressurizing for main pipes of heat power water supply, etc., wherein a plurality of pumps are connected with a main pipe, and a remote controller is used for controlling the plurality of pumps to pressurize the main pipe for water leakage detection, a plurality of remote controllers can be used for controlling the plurality of pumps, a plurality of remote controllers can be used for one pump, the remote controller and a host can be controlled one-to-one, and the plurality of pumps can be controlled together respectively. Therefore, the outdoor water leakage point can be detected by sufficient air quantity, the labor is saved, all pumps can be eliminated by only pressing the remote controller to stop when the leakage listening instrument is used for eliminating, and the method is more accurate than that of the method which is controlled by two persons in a matched mode. Compared with the prior art that the atmosphere pump detection outer net is very inconvenient to carry, the portable air pump detection outer net is convenient to carry through flexible and changeable multiple modes after improvement, and the detection from the assembly can be completed by one person.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
