The single-screw pump is a rotor-type positive displacement pump, which relies on the intermeshing of the screw and the bushing to produce volume changes in the suction cavity and the discharge cavity to transport liquid. It is an internal meshing closed screw pump. The main working parts are composed of a bushing (stator) with a double-ended helical cavity and a single-ended helical screw (rotor) meshing with it in the stator cavity. When the input shaft drives the rotor to make a planetary rotation around the center of the stator through the universal joint, the stator-rotor pair is continuously meshed to form a sealed cavity. - The rotor pair is transported to the extrusion end, and the medium sucked into the closed cavity flows through the stator without being stirred and destroyed.

Machinery industry needs nearly 10 billion pneumatic products in the next few years
At present, China's agriculture, water conservancy, energy, transportation, information, construction, environmental protection and other industries have developed rapidly. Therefore, a large amount of mechanical equipment is needed to meet the needs of its development. With the improvement of industrialization and automation, these equipments need a large number of high performance and high reliability hydraulic pneumatic and sealing elements. According to preliminary estimates, it is expected that the total domestic demand for hydraulic, hydraulic, pneumatic, and sealing products by 2010 will increase from 20 billion yuan (including about 900 million U.S. dollars worth of imports and nearly 300 million U.S. dollars) in 2005 to about 35 billion yuan (of which The import is about 1.5 billion U.S. dollars and the export is about 500 million U.S. dollars). Among them, hydraulic products increased from more than 10 billion yuan to 20 billion yuan, hydraulic products from more than 1 billion yuan to more than 2 billion yuan, pneumatic products from nearly 3 billion yuan to more than 5 billion yuan, and sealed products from more than 3 billion yuan Yuan increased to 7 billion yuan.
