feed flow by reducing the increasing rate of drive power source output when the feed flow becomes positive from approximately zero when a pump is started newly, in an operating method in which the number of multiple operating pumps connected in parallel with each other is increased or decreased....

Multiple modules connected in parallel high-capacity systems, it not only beautiful but also make the max power density for the user. Static Frequency Converter using DSP control technology with intelligent and automation: A. with 7 inch LCD touch screen...
Qi et al. examine the impact of connection configurations of underground heat exchangers on ground temperature and performance of GSHP systems. The heating performance of the GSHP system applied in a net zero energy building was investigated experimentally and numerically with series and parallel ...
Of course, if there is any load then the capacitor will immediately start discharging, and so it will be necessary to continually switch the capacitor back and forth between the in-parallel and in-series configurations in order to keep recharging it. To keep the output voltage relatively constan...
Syringe pump has plunger head retainer (10) with two retainer arms (111 and 112) mounted on shafts (113 and 114) extending parallel to the syringe axis. Each shaft carries gear (121 and 122), which is engaged by common gear wheel (142) mounted on threaded shaft (146). After the syrin...
The water enters the pump from the top left and passes through each of the four impellers in series, going from left to right. The water goes from the volute surrounding the discharge of one impeller to the suction of the next impeller. A pump stage is defined as that portion of a ...
Reducing ESR in the input capacitor implies multiple capacitors connected in parallel: N identical capacitors in parallel reduces the input ripple by N-1. Unfortunately, that approach is not very effective in terms of cost and pc-board area. ...
To overcome this limitation, two micropumps were placed in the channel and driven in different phases to reduce pulsation, and two pump configurations were tested. In addition to the typical parallel arrangement, a series arrangement with pumps at both ends of the linear flow path was also ...
