The idea to increase the backpressure is because the motor is overheating due to the pump impellers rotating too fast (making the motor run too fast, driving up the amps). This is the understanding anyways, certainly open to suggestions. The ideal pressure on the system we are shooting for is...
What is a common way to reduce the flow rate and increase the back pressure on a pump driven by an electric motor? Are flow rate limiting valves a good choice or are there better methods to use? Flow rates in the pipe of aprox. 8 USGPM, 50 psi to 60 psi. If more specific information is needed...
I am going over many of the older columns in a thermal generating plant, which have been exposed to a corrosive environment, mainly in the lower 6 to 8 inches of the column base. The steel is delaminating severly on some of them, and is deteriorating quite significantly with regards to its...
I am looking for ideas as to how to protect valves, gauges, and regulators that are part of the piping system for bunker C fuel that is pumped from a tank to a plant. Occasionally, the steam trace lines that run along the fuel line fail, and the lines freeze. Often, the fuel line can be saved...
I am searching for any information in the API650/653 codes that would govern the following situation:
The columns supporting the roof will have new wear plates installed underneath them during repair and replacement of the floor of a Bunker C storage tank. Some of the column bases sit over top...
I am wondering where I may refer to guides governing the placement of sumps to be installed in bottom of an oil tank. The issue is whether the sump position can be cut where two plates meet, or should the sump be positioned in the middle of a floor plate (to avoid possible issues of stress...
