In the sealing test, due to different wire materials, different waterproof technology, different wire diameter, different interface and other problems, at the same time, for the sealing test of wire, the parts tested by each manufacturer are not the same. This has become a recognized testing problem in the sealing testing industry. As a well-known tightness testing expert, Harris technology has provided dozens of tightness testing schemes for different wire and different testing parts.
Generally, the diameter of non engineering wire is small, the material of wire core is different, and the manufacturing process of manufacturers is also different. These conditions are enough to make the wire sealing test more difficult and make the test unstable.
At present, Harris technology has rich experience in the detection scheme of wire rod in the industry. Here, we will show you several detection schemes to provide reference for manufacturers who need to do the sealing test of wire rod
In order to better fix the wire, according to the wire shape, diameter, size, the scope to be tested, a specific mold is customized for the wire to assist the sealing test. Put the wire into the mold, and the upper and lower mold can be closed to form a sealed detection space, which can solve the detection problem that the wire is difficult to fix due to the structure. The following is the display of hermetic detection mold for wire of hiris technology.
How to deal with the requirements of wire characteristics for tightness test?
Wire characteristics: wire is used in all kinds of electrified equipment, so it has thousands of types, which also makes its sealing process, diameter, interface, wrapping material, bearing pressure, sealing test standards and requirements are not the same.
The difficulty of tightness test: because there are many factors affecting the tightness test of wire rod, the applicability of test equipment is greatly reduced, and the equipment investment cost of manufacturers is increased.
Hermes technology solutions: Hermes designs the tightness tester into three parts: tester, gas source and tooling. Because the tester, gas source and tooling are self-contained, they cooperate with each other in the detection, but do not affect each other, which improves the accuracy of sealing detection. According to the different detection wires, the corresponding tooling can be replaced, so as to achieve the function of one equipment to detect different products. In addition, in response to different testing standards, Harris technology is equipped with "positive and negative" pressure forms and eight basic testing modes, which can be selected or combined. It can support leakage test, blocking test, positive pressure test, negative pressure test and other seal test methods. Using 24 bit a / D conversion, 32-bit CPU operation, and fully independent development of industrial control operating system, with full touch human-computer interface. Built in RS232 serial port, RJ45 network port, USB communication interface, LTP external I / O control port, support a variety of communication protocols. The operability of the equipment is enhanced, and the detection function of the instrument is no longer single, but has the function of independent selection and setting, which can be better put into the waterproof detection of the whole line of wire rod, reduce the manpower input in production, and improve the production efficiency. The following figure shows the wire sealing tester developed by Harris technology.
All of the wire tightness detectors shown above have been put into production line, with strong applicability, fast detection efficiency and high precision, which are favored by many wire manufacturers.
