704 new sewage treatment plants passed the acceptance

Recently, at the acceptance meeting organized by the National Defense Science and Technology Commission, 704 self-developed MBR sequencing batch biochemical wastewater treatment and membrane separation technology devices passed the acceptance test. The device adopts a combination of sequencing batch biochemical process and membrane separation technology to treat domestic sewage and kitchen grey water. The experts at the meeting agreed that the technology has filled the domestic gap and reached the international advanced level. In 2003, 704 undertook the task of developing batch-type biochemical wastewater treatment and membrane separation technology devices. After technical and market research, principle prototype test, product prototype test and type approval test, 704 successfully manufactured the prototype in July 2005, and passed the approval of China Classification Society, and obtained the national invention patent and practical. New patents.

Pneumatic Products

Pneumatic products include pneumatic components, pneumatic joints, pneumatic valves, cylinders, pneumatic pipes and other products.

Pneumatic components work by the pressure of gas or the force generated by expansion, that is, the elastic energy of compressed air is converted into kinetic energy. Such as cylinder, pneumatic motor, steam engine, etc. Pneumatic component is a form of power transmission, also known as energy conversion device, which uses gas pressure to transfer energy.

Pneumatic quick connector is a kind of quick connector which is mainly used for air piping and pneumatic tools. It can connect or disconnect the pipeline without tools. When the connector is not connected - when the parent's ferrule moves to the other end, the stainless steel ball will automatically roll outward, and the daughter will be disconnected under the action of the common valve spring force of the parent and the daughter, and the daughter and the parent's valves will be closed respectively, The fluid flow is blocked instantaneously.

Pneumatic Valve is driven by compressed air. It can be used to control the flow of air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. In the current market economy environment, it is not perfect. For the sake of product competition, the manufacturers of pneumatic valves carry out different innovations under the concept of unified design of pneumatic valves, forming their own enterprise standards and product personality. Therefore, it is very necessary to put forward the technical requirements in detail when purchasing the pneumatic valve and reach a consensus with the manufacturer as an annex to the pneumatic valve purchase contract. This kind of valve should be installed horizontally in the pipeline.
