Method and system for water treatment and water circulation in ultrasonic detection equipment

Abstract

The invention discloses a method and a system for water treatment and water circulation in ultrasonic detection equipment. A water treatment and water circulation system is additionally arranged in an electrical contact welding quality ultrasonic nondestructive testing system, namely a measurement water bath of the ultrasonic nondestructive testing system is connected to a first water outlet and a first water inlet of a water pump consisting of two electromagnetic valves, a water storage tank is connected to a second water outlet and a second water inlet of a water pump which consists of another two electromagnetic valves, so that water circulation can be realized by controlling the switching on and switching off of the four electromagnetic valves, namely controlling water supply and water drainage of the measurement water bath and water filling and water drainage of the water storage tank in the measurement process; and a filter is arranged between the water storage tank and the measurement water bath, and is used for purifying water. The method and the system can be used for realizing high-efficiency filling and drainage of ultrasonic coupling medium water, improving the working environment of operators, and guaranteeing the purification quality of the coupling medium water and the accuracy of ultrasonic detection.

Description

technical field [0001] The invention relates to an ultrasonic testing device, in particular to a water treatment and water circulation method and system in the field of ultrasonic non-destructive testing of welding quality of electric contact contacts. Background technique [0002] In the ultrasonic non-destructive testing process of the welding quality of the existing electrical contact contacts, water is used as the most commonly used conducting medium, and the welding quality testing of the electrical contact workpieces is carried out by immersion. The quality of water used as a coupling medium directly affects the detection accuracy of ultrasonic nondestructive testing, and the immersion and removal of electrical contact workpieces brings harsh working conditions to operators. [0003] The US OKOS company has launched ultrasonic testing products, but its products do not include the treatment and control of coupling medium water. Similarly, GE Company in the United State...
