Cottle screw on the technical description of Xianyang Qin Wei Compressor Co. production Cottle brand screw machine has advanced structure, smooth operation, low noise, and high reliability. Long life, low maintenance costs, low energy consumption, including the following aspects: 1. The use of imported technology and components, the assembly, direct-attached structure Qin Wei air compressor, so did almost no loss of power motor spread to the nose, which effectively reduces the speed to make the life of the host to be extended. This structure is called the big nose, low speed. 2. Xianyang Qin Wei screw compressor for Cottle specially after the installation of a cooler. Due to air in the compression process will produce heat, hot air will expand, as reflected in the expanded air displacement and the actual displacement has some desired value, after the installation of after-cooler has solved this problem Cottle air compressor, air compressor displacement so Cottle optimum value. 3. C?te children compressor motor with protection class IP54, high degree of protection for the motor section, high life, Xianyang Qin Wei currently using this type of compressor motors for many years without a single Depot. The control system uses a computer-controlled, can be done 24 hours unattended. 5. Siemens distribution system. Good control system can always maintain a high pressure pneumatic, pneumatic mechanical efficiency is increased by about 10%. Two indicators to detect air filtration equipment holistic approach to detect the main air filter efficiency and leakage coefficient, the sum of these two indicators for individual equipment is 100%, while on the integrity of the filter is detected more complex. Brief detection method, these methods are from the actual operation of the results obtained with the implementation of the standards are not contradictory, but because the evaluation is based on the average, so it was not included in the calculation of error and confidence interval , the statistical characteristics of the particles can also be taken into account. Accordance with the relevant provisions of the method used to filter air compressor efficiency evaluation has been installed, only to calculate the average value of its parameters, you can also use the concept of statistics, the standard deviation and 96% confidence range, but some experts believe that such a methods are not much meaning since the whole method is based on the actual assumptions can not be completed. 1, the first assumption for air filter inlet particle concentration in the entire surface area of ??the terminal is not changed, so how to detect? The answer is unable to detect outliers concentration can reach 1/10 or even several times. 2. The second assumption is assumed filter outlet wind speed is constant, but the reality of the wind speed is not possible to maintain such a state, but allows a certain variation within ± 20% of the average value . 3. The third assumption is based on scanning speed, which is also require constant, but when the actual work of the hands of people can not maintain strict uniform motion, would have a slight jitter and pauses. So screw air compressor, assuming more of this series with the actual situation is a far cry from the reality of the emergence of a variety of factors are very random, that these assumptions to avoid reality, clearly beyond 96% confidence limit that should be considered in the scope of these methods.
