6.1.37.2If ASME B1.1 threads have been specified, the thread series shall be the varying-pitch series UNC for sizes up to 1 in. and 8 UN for sizes greater than 1 in. All threads shall be Class 2 or 3. 如果指定使用了ASME B1.1 螺纹,那尺寸到了1英寸前的螺栓螺纹系列应该是UNC的可变螺距...
Real systems have friction, so the flow increase becomes a little less than double. The higher the friction ratio, the more acute this becomes. Withvery high friction ratios, the concept of parallel operation should be replaced by series pumping. ...
In addition to customizable appearances, the pumpabilities of soft electronic pumps could also be customized by changing applied voltage, electrode configuration, liquid type, or electrode series/parallel integration use, etc. Supplementary Fig. 8 shows experimental setups for testing the performances of...
parallel system is presented inFig. 6. The solar thermal collector can act as a heat source of the heat pump unit, either primary or supplementary, and either directly or via buffer storage. This concept is denoted as ‘serial’. When coupled in series, the capturedheat energyis fed into ...
Time dependency analysis: improvement in mean cough severity according to the duration of acid-suppressive treatment with proton pump inhibitors (Y-axis shows the change in cough severity expressed as SMD—standardized mean difference; the X-axis shows the duration of acid-suppressive therapy in weeks...
G Series Air-Ring Vacuum Pump Adopts Wide Pressure Double Frequency, Find Details and Price about Vacuum Pump Pump from G Series Air-Ring Vacuum Pump Adopts Wide Pressure Double Frequency - Sichuan Mighty Machinery Co. Ltd.
Exergo-economic comparisons of solar cooling systems coupled to series/parallel absorption chiller types considering the lowest heat transfer area The sensitivity analysis demonstrates that except for temperatures of cooling water, returned chilled water, and temperature difference of driving steam from ......
A peristaltic pump having an array of compressible tubes in parallel substantially coplanar relationship with each other. A cylindrical rotor assembly including a series of equally spaced rollers around its periphery is located adjacent one side of the array of tubes, and a resiliently mounted platen...
A series of electromagnetic lenses in the electron column are used to control the current and diameter of the electron beam which strikes the sample surface. Varying the current to the upper, condensing lens (or lenses) changes its focal length. This controls the flux of electrons which will ...
device that contained two sac-type blood pumps that are placed in parallel and use compressed air to eject blood. This pump is completely self-regulated and provides pulsatile ECMO return. Three neonatal patients with respiratory failure were successfully supported in Japan with use of this device....
