Two stage screw compression technology uses isobaric ratio principle to set the inter-stage pressure for the first and second stage compression, which not only reduces compression ratio for each stage of compression and air leakage, but also greatly improves volumetric efficiency and adiabatic efficiency.
This two stage compressor lowers the compression ratio compared with a single air compressor, reduces air leakage, bearing load and ensures a longer life service and volumetric efficiency of the air end. With our optimization, bearings have a life span of over 150,000 hours, and low noise, low vibration, safe and reliable operation is ensured.
improves the efficiency of screw compressor obviously and the compression process along saturated vapor line is realized if enough water is injected. The volumetric and isentropic efficiency is not sensitive with the water if more than flow rate of 35L/h is injected. The discharge temperature decreases from 133.4℃ to 108℃ with water
Twin screw compressor This is similar to the one screw but contains a couple of intermeshing rotors or screws: male screw has four or five spiral blades and the female screw six or seven helical grooves, 4 - + 6, 5 + 6 or 5 + 7, male-female combinations.

Atlas Copco 35 HP Rotary Screw Air Compressor, 132 CFM @ 150 PSI, Fixed Speed | GA26-150 AP 208-230/460 API Atlas Copco GA Series 15-26 - Single Stage, air-cooled and oil injected ...
Measures are usually taken to dissipate that heat to maintain the compressor’s mechanical integrity. Screw compressors enjoy high volumetric efficiencies as long as their clearances are kept extremely small. Performance of the screw compressor depends on the rotor speed as long as leakage can be kept to a minimum.
Jun 01, 2015 · Compressor capacity and horsepower are affected by piston displacement and cylinder clearance. The flow capacity of a given cylinder is a function of piston displacement and volumetric efficiency. Volumetric efficiency is a function of cylinder clearance, compression ratio and the properties of the gas being compressed.
The thermodynamic parameters of interest are the volumetric efficiency and the isentropic efficiency. It is found that the volumetric efficiency decreases with pressure ratio; however, depending on the built-in volume ratio of the compressor, the maximum value of the isentropic efficiency occurs in a narrow range of values for the pressure ...

of the oil-injected screw compressor. Some CFD analysis and dynamic simulation was done to improve the accuracy of theoretical analysis. Liu et al. (2012) developed a screw compressor model for refrigeration system simulation and the model could be used to optimize the built-in volumetric ratio of screw compressor. Those models provided Efficiency advantage: The intake filter is positioned in the coolest part of the cooling airflow and takes in the air for compression at the lowest temperature. This results in an optimized volumetric efficiency and output from the compressor. The air/oil cooler, on the other hand, is positioned at the top of the compressor.
Large pressure differentials, combined with volumetric efficiency rates: that is what differentiates AERZEN VR compressors from other rotary lobe machines that also operate according to the positive displacement principle with internal compression. A special 4+6 rotary profile brings this plus efficiency to process gas applications.
The working process of twin screw air compressor under unload conditions was analyzed. Mathematical model describing the working process of oil injected twin screw compressor under unload conditions was established based on the laws of perfect gas and standard thermodynamic relations, considering the effects of oil injection, gas-oil heat transfer, internal leakage etc. Jul 06, 2015 · To evaluate the performance of an existing compressor, the objective is to calculate the compressor efficiency (η) and power requirement. Known and measured properties are: a. Standard condition gas volume flow rate (q S) or gas mass rate b. Gas composition (z i) c. Suction pressure (P 1) and temperature (T 1) d.
The following items impact the efficiency of blowers: Temperature rise: Temperature rise is the difference between the inlet temperature and the discharge temperature.The increase in temperature is caused primarily by the heat of compression according to the gas laws—plus inefficiencies within the blower and slip, which is internal recirculation and friction.
The belt-driven compressor with integrated frequency controller ensures the best efficiency: as your compressed air requirements decrease, the energy consumption of the compressors decreases, idle times are minimized and pressure fluctuations are leveled off. Smooth starts and stops protect the materials and extend the lifespan. This makes compressor lighter and cheaper. 4) Heat removal during condensation is reduced hence size of condenser is reduced. 5) Volumetric efficiency of compressor increases due to reduced pressure ratio in each stage. 6) Temperature at end of compression would be less. As a result lubrication would be effective. Hence, compressor life increases.

High Pressure Screw Compressor (TP22G/TP30G) is exported and supplied by us from Wenling City, Zhejiang. This product has a very simple design structure and assures the user of no host leakage. The energy efficiency of the product can help the user to reduce the electricity bill up to 25%. The excellent volumetric efficiency
Feb 11, 2019 · Unlike the reciprocating machine, there are no trapped pockets of gas remaining in the machine. As a result, the volumetric efficiency of a screw compressor remains very high as pressure differentials across the machine increase. Figure 7 provides a comparison of the reciprocating and screw machines at the completion of the discharge process. In View (B) we are still looking at the bottom of the rotors, but we are now looking from the opposite end. This compressor is also maintenance-friendly. Adjusting the coupling alignment is simple as the motor comes with a standard flanged motor (B35) design. The operating conditions, including the process line, allow for a stable process. The rotor design of this compressor, the same as the SCV series, allows for high volumetric efficiency
