Eight Features of DC Transmission in DC Electric Diaphragm Pumps

[Asia pump network hearing] DC electric diaphragm pump is clearly the use of DC transmission, rather than AC transmission, then what are the advantages of DC transmission compared with AC transmission? Below we introduce the DC electric diaphragm pump DC transmission eight characteristics. ① When the transmission of the same power, the DC line low cost, overhead line tower structure is simple, the line corridor narrow, with the insulation level of the cable can run at higher voltage; ② DC power transmission and power loss is small; ③ on the communication interference The line itself does not need reactive compensation; ⑤ HVDC transmission line contact the two ends of the exchange system does not need to synchronize the operation, so can be used to achieve different Frequency or the same frequency AC system; ⑥ DC transmission line itself does not exist the inherent stability of AC transmission, transmission distance and power are not limited by the stability of the synchronous operation of the power system; ⑦ by the DC transmission line interconnected Of the AC system short circuit capacity will not significantly increase due to the interconnection; ⑧ DC transmission line power and current regulation and control easier and faster, you can achieve a variety of regulation and control. If the AC and DC run side by side, helps to improve the stability of the AC system and improve the operating characteristics of the entire system.

DBB Plug Valve

DBB Plug Valve called double block-and-bleed plug valves which is high-integrity, positive shut-off valves. DBB plug valve have advantages of easy maintenanceand repair. The valve size is from 2" to 24" with matching valve pressure from class 150 to class 900. DBB plug valve normally used in oil tank in airport with double sealing to protect oil pipeline from any risks, such as fire or leakage etc.
