The national standard of "Differential Pressure Air Leak Detector" was implemented
2017-09-19
A few days ago, the national standard of "Differential Pressure Air Leak Detector" drafted by Yibo Pneumatics passed the expert review, approved by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China and the Standardization Administration of the People's Republic of China, and was released on December 23, 2010 and implemented on October 1, 2011.
In the past, traditional leak detection methods, such as the water-immersed visual bubble method or the pressure gauge pointer reading method, had low detection accuracy and efficiency, and the influence of human factors was great, so it was impossible to realize automatic quantitative leak detection.
Relying on the high-precision measurement technology of the differential pressure sensor, the differential pressure leak detector realizes direct differential pressure differential leak detection and overcomes the influence of ambient temperature. It can objectively automatically judge good and defective products, and the judgment output signal can also be used to drive external equipment, which is conducive to the realization of automation and has a high cost performance.
This standard is compiled on the basis of summarizing the differential pressure air leak detector, giving the structure and product testing standards of the general leak detector and sealing components leak detector, compared with the existing similar standards at home and abroad, the selected test methods are more advanced, the content is more reasonable and perfect, the differential pressure air leak detector has made a positive contribution to the fields of automobiles, aviation, electronics, gas equipment, etc., and also provides a wider development space for it.

Dynamic Balance Tester - Encyclopedia
The dynamic balance tester is easily used for the measurement of the dynamic balance of rotating machinery such as steam turbines, water turbines, agricultural machines, centrifuges, fans, water pumps, etc., the correction of dynamic balance and signal analysis. A portable field balancing instrument that combines advanced embedded computer technology and proven balancing technology. It has many functions such as on-site vibration data measurement, vibration analysis and single-sided and double-sided dynamic balancing, which is simple and easy to use, and is the most ideal tool for predictive maintenance and repair of industrial and mining enterprises, especially for equipment manufacturers and vibration technology service organizations such as fans and motors. It can not only perform dynamic balancing of equipment in the field, but also perform vibration detection and vibration analysis.
DetailIn order to promote the interaction between the upstream and downstream of the industrial chain, improve the equipment level and standardization level of China's wheel industry, and promote the sustainable and healthy development of China's wheel industry.
Detail1. What is it? It is generally believed that the dynamic balancing of automobiles refers to the mass balance of tires along the axis, which is commonly referred to as the installation of balance weights. When the car leaves the factory, the tires have been dynamically balanced. But in use, the balance can be disrupted. When changing tires, a balance check is also carried out. The dynamic balancing of the wheels should be carried out on a special dynamic balancing machine. Automatic Balancing Machine Manufacturer-Shenyang Linmin Intelligent Testing Equipment Co., Ltd.-Shenyang Linmin Intelligent Testing Equipment Co., Ltd. is a company specializing in R&D, production and sales of automatic runout and dynamic balance testing equipment, and provides users with a series of solutions.
