The two pumps (P1,P2) each have their own drive and at least one of the two pumps can be operated in the reverse direction in the same way as in the forward direction. The control device (6) operates on the drive of the second pump to set the direction of rotation. All the non-...
4) Centrifugal pumps in series and parallel 离心泵的串并联 5) series and parallel mixed pumping station 串并联混合泵站 6) multiple-series connection 串联并联 补充资料:电力电子器件的串并联联接 电力电子器件串联和并联是为了提高器件的电压和电流容量。单个电力电子器件能承受的正、反向电压是一定的,能通过...
Note! In practice the combined head and volume flow moves along the system curve as indicated from 1 to 3. point 3 is where the system operates with both pumps running point 1 is where the system operates with one pump running In practice, if one of the pumps in parallel or series st...
5) series and parallel connection of slurry pumps 泥浆泵串并联 6) pump with series or parallel connection impellers 叶轮串并联泵 补充资料:排灌机械:高效自吸式离心泵 离心泵分为一般离心式水泵和自吸式离心泵两种。自吸式离心泵不需启动灌水,小型离心泵采用自吸形式,使用很方便。
Thus, dual source heat pumps are interesting since they combine the best features of parallel and series configuration SHP systems. In this case, the heat pump can switch between solar energy or other energy source, such as ambient air. The control strategy for the heat pump using a switching...
If you have pumps in series make the flow a fixed number and input the corresponding head units. Alternatively, you can create an approximate pump curve using the equation H = A + BQ^2. In excel use linear regression simply by taking your Q-H data and squaring the Q. Perform the regre...
The chemical inside it is known as electrolyte. The chemical reaction going inside pumps around the circuit around which a battery is connected, which provides a power to the flash. Cell Type There are many electrochemical cells produced, with varying designs and chemical processes, including galvan...
An innovative structure of pumps with high flow rate and multiple operating conditions is proposed in this paper to achieve series and parallel operation. It established an automatic optimization platform that integrates functions such as 3D modeling, mesh generation, computational fluid dynamics, and ...
This invention relates generally to motorpumps, and particularly to a series-parallel motor-pump unit. In making deep water well pump installations it is customary to select the size of pump on a basis of a substantially constant head and capacity. In many instances, however, a wide variation...
