Abstract

The system can detect very small leaks on the seam welding of radiators, by detecting the sound and air escaping using a high quality microphone and amplifier. To achieve this sound waves, and air pressure of 11 bar are introduced into the radiator via two of the connector holes. The other two connection holes are temporarily sealed. By moving a microphone along the welding seam, any crack or hole will be detected because the microphone will pick up leaking sound waves.

Description

TITLE: LEAK DETECTION FOR SEAMED WELDED DOMESTIC RADIATORS DESCRIPTION: This system is designed to detect any leaks on the seamed welding of domestic heating radiators.
HOW IT WORKS: For domestic heating radiators.
Apply audible sound of specific frequencies and waveform and air pressure between 10-11 bar in to radiator via two of the four available pipe connections. Plug the other two connections temporarily.
Using a high quality audio microphone and specially designed amplifiers, any leak on the seam welding can be detected by placing the microphone near the weld at a appropriate distance and angle. If there is a fine crack on the seam welding air and hence sound will escape and will be detected from the microphone. The amplifiers will enhance the signal and raise the alarm for rejection. The whole process can be done automatically.

Claims (7)

  1. CLAIMS 1. A leak detection system for domestic radiators, based on the principle that air and sound waves escaping through cracks or holes of a seam welding can be detected by high quality microphone and amplifier system.
  2. 2. A leak detection system for domestic radiators, as claimed in Claim 1 where the compressed air of 11 bar and sound waves by means of air compressor and audio frequency generators.
  3. 3. A leak detection system for domestic radiators, as claimed in Claim 1 and Claim 2 where the sound is injected into the radiator by means of a small transducer placed into one of the radiator connector holes, and air pressure applied in the radiator at the other connection hole while the other remaining holes are temporarily sealed.
  4. 4. A leak detection system for domestic radiators, as claimed in any preceding Claims where a high quality microphone mounted on an automatically or manually moving rail moves along the seam weld within 10mm away from it to detect any escaping sound waves or compressed air.
  5. 5. A leak detection system for domestic radiators, as claimed in any preceding Claims, where a signal preamplifier and amplifier is used to process signals generated from the high quality microphone and raise an audible and visible digital alarm to reject that particular radiator.
  6. 6. A leak detection system for domestic radiators, as claimed in any preceding Claims, which is made from metal, plastic material or wood, electrical and electronic components and pneumatic components, or from any combination of these materials.
  7. 7. A leak detection system for domestic radiators, as herein described and illustrated in the accompanying drawing no. 1.
