=====================================
Frc301 control valve after the pump together flow control, in crude oil processing less than 900 tons, the pump will be variable flow, variable pressure control. The potential of frequency conversion to save electricity is considerable. The actual flow control signal of the pump shall be determined by the flow required by the heat exchanger behind the four-way regulating valve. If we can find out the exact mathematical model between the flow of the four-way regulating valve and the flow of the raw material pump, we can completely control the pump, and thus cancel the valve control device, which will further improve the automatic closed-loop control of the pump, at the same time, further energy saving and consumption reduction results will be achieved. At the same time, the process should also be studied when the heat exchanger pressure reduction process indicators should be adjusted and its impact on the quality of finished products. After the frequency conversion transformation of the feed pump has been completed, the power saving effect is quite obvious. The actual electricity saving cost has exceeded 1.5 million yuan in the two years of operation; the operating noise of the motor is obviously lower than that of the power frequency operation, at the same time, because of the reduction of the pump outlet pressure, the sealing condition of the whole system can be improved. Pump load plays an extremely important role in the petrochemical industry. In order to regulate the flow of pumps, many methods have been developed, to sum up, it is no more than: Using Control Valve or throttle valve throttle change pipeline curve; using speed control technology to pump speed change pump operating curve. The relative humidity around PLC is recommended to be 35% ~ 85% . High humidity often causes the deterioration of electrical insulation and the corrosion of metal parts. If restricted by the setting place, the PLC electric control device has to be placed in a place with high humidity and much dust, the following technical measures can be adopted for moisture-proof and dust-proof design.。

那時(shí)的青春萌動(dòng)是多么美的一種情愫，一直到很久都會(huì)想著你曾經(jīng)說(shuō)過(guò)的話，還傻傻地以為這些話只會(huì)對(duì)我一人說(shuō)，也常常幻想著會(huì)不會(huì)上演電視里的那種情景，在一個(gè)偶然的機(jī)會(huì)我們邂逅了……到后來(lái)慢慢明白，什么東西久了都會(huì)變質(zhì)，無(wú)論什么也都不會(huì)有永遠(yuǎn)的美好，只有精彩的瞬間;亦不是你我變了，是這一切一切都抵不過(guò)時(shí)間的摧殘。
