What is a compressor symbol?
Compressor. The symbol for a compressor is similar to the air motor symbol. The addition of a diagonal line arrow through the circle indicates variable displacement, as opposed to a fixed displacement compressor which would have no diagonal line arrow.
What are the 3 components of a centrifugal compressor?
A simple centrifugal compressor stage has four components (listed in order of throughflow): inlet, impeller/rotor, diffuser, and collector.
What is centrifugal type compressor?
A centrifugal compressor is a type of dynamic compressor, or turbo compressor, with a radial design. Unlike displacement compressors that work at a constant flow, dynamic compressors work at a constant pressure and the performance is affected by external conditions such as changes in inlet temperatures.
What are centrifugal compressors used for?
compressors. Centrifugal compressors increase the kinetic energy of the gas with a high-speed impeller and then convert this energy into increased pressure in a divergent outlet passage called the diffuser. Centrifugal compressors are particularly suited for compressing large volumes of gas to moderate pressures.
What is the symbol for pump?
The base symbol for the hydraulic pump (Figure 1) is actually quite simple. It starts with the standard circle and a directional arrow pointing out one end from within that circle. The solid-filled triangle makes this a hydraulic pump while pneumatic pumps (and most pneumatic symbols) are outlines only.
What are the pneumatic symbols?
Directional air control valves are the building blocks of pneumatic control. Pneumatic circuit symbols representing these valves provide detailed information about the valve they represent. Symbols show the methods of actuation, the number of positions, the flow paths and the number of ports.
What is impeller and diffuser?
A diffuser is a set of stationary vanes that surround the impeller. The purpose of the diffuser is to increase the efficiency centrifugal pump by allowing a more gradual expansion and less turbulent area for the liquid to reduce in velocity.
What is pressure ratio in centrifugal compressor?
A multistage centrifugal compressor (i.e., a machine with multiple stages) can achieve, with natural gas, a pressure ratio of about 4–5, which equates to about 70,000–90,000 ft lb/lb of head. The temperature rise resulting from this amount of head is usually a limiting factor.
How do centrifugal compressors work?
A centrifugal compressor imparts kinetic energy into the airstream by increasing the velocity of the air using a rotating element and then converts this kinetic energy into potential energy in the form of pressure.
