Classification and definition of Cottle compressor as shown in Figure 1. Classification 2. Definitions 2.1 displacement compressors: by displacement compressor Wei Qin moving parts, so that the order of a certain volume of gas inhaled and send the enclosed space to increase static pressure compressor. Reciprocating compressor shaft drive 2.2: Due to the rotation axis of movement so that the moving parts in the compression chamber for reciprocating linear motion Cottle compressor to achieve gas suction and compression displacement compressors. 2.3 Rotary Compressor: a positive displacement compressor, a member whose movement is movement in a cylinder or several rotor. By displacement volume slider, one or more engagement parts, or the movement of the rotor itself is achieved. 2.4 powered compressors: With continuous gas inlet to the outlet, its kinetic energy is converted to potential energy of a compressor to increase gas pressure. 2.5 turbine compressor: a rotary vane wheel impeller power compressors. 2.6 Axial turbine compressor: converting the kinetic energy of the turbine compressor is basically bladed axial flow rotary wheel and the diffuser. 2.7 runoff turbine compressor centrifugal compressor that: convert energy turbine compressor is essentially radial flow impeller and diffuser in. 2.8 Ejector: no moving elements, auxiliary fluid system by converting the kinetic energy to achieve compression power compressors. Under the compressor business "new normal" restructuring plan to be upgraded externally moment, the "new normal" has become the hottest economy keywords. "New" means different from the past of the new normal; "moderate" air compressor price, meaning relative stability of the new normal. Compressor industry, how as it? Some media said that China's economic development-related companies to adjust to the compressor space left, not to be missed opportunity. Employees across the business should work together to seize the opportunity to digest the risk of complete transformation and upgrading. Faced with domestic economic slowdown, industry overcapacity, compressor companies should take this chance to sea, looking for new growth markets. It is reported that, as in the field of oral comprehensive treatment necessary air supply equipment - air compressor, it is essential in the daily medical career services; the face of a large number of Chinese high-speed rail projects approved, car compressors, portable compressors will usher in a new growth point; along with Chinese nuclear power plant construction and processing of nuclear waste, compressor market will usher in new opportunities ...... how to take advantage of these new growth point compressor, seize new areas of application, is Enterprises should always pay attention to and one of the issues to consider. Seize growth is a priority of the current industry downturn companies face facing new demands and customer-facing point, compressor companies should practice by themselves, driven by intelligent upgrade the entire industry, intelligent manufacturing equipment to drive the global enterprise collaboration development, to create China's first "Industry 4.0" demonstration zone. With the country's macroeconomic enter the new normal, compressor companies as the industry adjustment, future compressor business should continue to enhance independent innovation capability and improve cost control, to further improve international and improve the anti-risk ability, and will also strengthen construction industry chain, accelerate adapt to the new norm.
