Valve leakage detector ACEPOM361 is an instrument that USES the principle of high frequency vibration to check for leakage in the system.When there is a leak in a system, either a positive pressure system or a negative pressure system (a vacuum system), turbulence occurs when gas passes through the leak.When the leakage hole is small, the turbulence generates high_frequency vibration near the leakage hole, and the high_frequency vibration signal can be received by the multi_function leakage detector.After receiving the signal, the instrument transforms to digital indication and sound signal.The location of system leaks can be found through headphones, digital strength indicators, and light beams.

Application range：

●Contact measurement: can detect bearing gear wear and valve leakage, and check the vacuum system leakage.

●Non_contact measurement: pressure, vacuum leakage, arc, corona, discharge can be measured and the tightness of vessels, pipes, heat exchangers, heat exchangers, etc. can be detected through signal transmission and reception.

Inspection Method：

lValve, steam trap detection: with the contact sensor, the metal needle pointing and touching the valve shell and valve on both sides of the wall, the closer to the valve to observe the greater the decibel value, the greater the sound heard, with this method can be checked to the valve leakage.

lMechanical fault detection: the contact sensor is used to observe the decibel value reading of the instrument and to listen for the internal sound. If necessary, it can be compared with the original recorded value, or with the equipment of the same type. This method can be used to detect the dynamic and static friction of gears, bearings, and steam turbines or other rotating machinery.

l Pressure and vacuum leak detection: use contact or non_contact sensors to scan around the suspected leak hole. The closer you are to the leak point, the greater the decibel value indication of the instrument, and the further away from the leak point, the smaller the decibel value indication of the instrument. Listen to the sound through the headset.If there are other interferences in the environment, and the leakage point cannot be determined, the interference source should be shielded (such as using cardboard to fend off), the anti_interference ability of the contact sensor is greater than that of the non-contact sensor.

l Electrical equipment check: use sensors, scan around the required inspection equipment, the nearer the discharge position, instrument indicated value, the greater the decibel value the farther you go from discharge position, the instrument, the smaller the db values indicate headset "PaPa" sound could be heard at the same time, "buzz" sound, etc., if you can't hear a sound, generally there is no discharge phenomenon, when there is interference can be shielding measures (such as cardboard gear, etc.).Must note: in the inspection of electrical equipment, must comply with the electrical equipment safety regulations of each enterprise, away from a certain safety distance.

l Heat exchanger tubes check: with non_contact sensor, the signal emission instrument into the side of the container, or the launch of the signal transponder steam head on the side of the container ports, and other things closed port leak, with multifunctional detector in the pipe of water side end scanning, the nearer the copper pipe leakage, db values indicate.In this way, the leaking copper pipe can be found root by root.In the inspection process can be used to monitor the headset and the operation of half of the cracked rehydrator can also check the leakage of the steel pipe.

lEmpty containers, pipes, capsule, door to wait the rigor of check: with non_contact sensor signal emission instrument container that is put in the check and seal port or hatch, multifunction tester in the external scanning, if there are funnelled or rigor, instrument decibel value get bigger, and the nearer the leak position, the greater the indicated value of instrument, and use headphones listening can judge the existence of the leak, can switch instrument sensitivity to find when necessary.
