What are the popular types of air tightness detectors currently on the market??Based on this question today, Hirays Technology collected the purchase status of air tightness testers from manufacturers in various industries.at the same timeQuery informationPlaceBased on the collected demand for air tightness detectors on the market, Hirays Technology will popularize the most commonly used brands of air tightness detectors on the market.as well asAir tightness detector model types.

Hiraysi Technology is engaged in the air tightness testing industryIn 2011, more than 800 old customers in the Hirays Technology market have a very good understanding of the HC classic series air tightness testers of Hirays Technology, both in terms of the working principle of the air tightness tester and the stability of the tester.For new customers who have not come into contact with the air tightness tester of Hirays Technology, how to choose an air tightness tester? Which brand of air tightness tester should be chosen? Which model of air tightness tester is the best? These questions still make manufacturers do not know how to make decisions.Hirays Technology will introduce the types and models of air tightness testers to people in the industry.

1. According to the classification of test methods, the types of air tightness testers commonly used on the market are as follows:

Type 1: Positive pressure air tightness detector

Through our precision pressure regulating valve, a certain pressure of compressed air is charged into the inside of the test product, and at the same time, real-time attention is paid to the gas changes in the product on the Heris precision detector. By paying attention to the gas changes, the product leakage can be judged.leakor not.Our positive pressure air tightness tester has three different pressure testers: low pressure, standard and high pressure.

The second type: negative pressure air tightness detector

Negative pressure air tightness detector is also called vacuum air tightness detector.It means to extract the air from the product, and the inside of the product will be in a vacuum state. At the same time, the Haris precision detector will pay attention in real time to whether the external gas will leak into the product to determine whether the product is leaking.leakor not.

The third type: flow tester

Use the method of instantaneous flow loss to conduct a sealing test on the product being tested.It is divided into mass flow detection and volume flow detection.(Generally used in pipeline obstruction testing.)

The main principle is that the sensor directly detects the leakage of the product.leakrate and display it in real time, which can basically eliminate the need for the original pressure drop method to leakleakThe time in the test is accumulated, the test speed is fast, and the leakage unit can be directly displayed. It is suitable for products that require test efficiency.

The fourth type: multi-channel air tightness tester

along withMany manufacturers and customersof production efficiencyimprove, one tester corresponding to one product can no longer meet the needs of customers. Multi-channel air tightness testers have been popularized in the market, and can test multiple products at the same time. This is the mainstream air tightness tester testing method on the market.

The air tightness tester is also called a tightness tester or a waterproof tester.Although they have different names, they are all used to test the tightness of products.The principle of the instrument is to use pressure attenuation to detect the tightness of a product.The so-called pressure decay method means to pressurize a product and observe the pressure change of the gas.There are two situations here. One is that the product itself has an inflation hole. We will directly inflate and pressurize the product, then cut off the air source and observe the changes in gas pressure. If the pressure drops, it means that the product is leaking. If it does not drop, it is good.The second type is that the product does not have an inflatable hole. We need to make a sealed cavity that is the same size as the product shape and specifications, that is, an abrasive mold, and try to fit the product as much as possible, because the detection results will be more accurate. Then pressurize the gas, and the gas will fill the space between the product and the abrasive mold. Then we also cut off the air source and detect whether the gas pressure has dropped. If there is a leak, the gas has leaked into the product. If there is no drop, it is good.Compressed gas is mainly used to detect whether a product is leaking.leak.Because this air tightness testing method is simple to operate, non-destructive testing of the tested products, and is currently the most advanced testing method, it has quickly been welcomed by customers.

Before there was air tightness testing, many manufacturers used the method of soaking in water to test whether a product is waterproof.The product needs to be placed in water and needs to wait for the product to dry before its air tightness can be tested again, which is a cumbersome procedure.;At the same time, if many electronic products leakleak&l
