China's production of Vacuum equipment is 30 years from the beginning of the 20th century, after almost 70 years of development, our full range of vacuum equipment, their quality has improved steadily, largely to meet domestic market demand. China's accession to the WTO is becoming increasingly fierce competition in the international market, while China's product quality and the level of vacuum equipment, there are still large gaps in dire need of calm and reflection, to study measures to strive for in the shortest possible period of time to catch up with international advanced level. Rotary vane pump main production enterprises markedly improved the quality of appearance My rotary vane pump production from design level to the processing and manufacturing to performance quality have been maturing. The main production relatively stable product quality, appearance quality has markedly improved. Over the past long-standing fuel injection, oil spills in recent years, a certain issue of control, rotary vane material performance has improved to some extent increased the reliability of rotary vane pumps. International Trust and Investment Co., Ltd. produced Nanguang 2XZ-8A Direct rotary vane pump is a rotary vane pump in recent years, few new varieties of products, from Pu-speed pumps to high-speed pump, at the technical level that has a definite breakthrough, solving under the conditions of high temperature high-speed operation, parts easy to aging, easy to wear problems.
