Help needed with hot oil reciprocating pump! ! Urgent
Thread Content
The bottom of the slurry tower in our catalytic unit is connected to a pump of model 2QYR-112/25, with a production date of November 1974; the manufacturer is Beijing No. 2 General Machinery Factory. Due to coking in the process distillation system, the production requires operating the reciprocating pump while the plant is running. Medium: slurry. Temperature: 330°C. Since this pump has never been operated in normal production, it is usually used for starting up and shutting down. Is there anyone who can determine the design operating temperature of this pump based on its model? Based on the current technical requirements, can this pump meet the demands under these operating conditions? I consulted the technical staff at Benxi Water Pump Factory regarding this issue, and it is common for high-temperature hot oil reciprocating pumps to have cooling water at the packing area. And I didn’t have it on site.
A pump from 1974 – an antique!
High-temperature hot oil slurry, pump from 1974 – can another pump be ordered?
For a reciprocating pump, as long as it can drive the vehicle, that’s enough; if there’s a problem, it can just stop. There’s nothing mysterious about it, right? If you’re worried, have a disassembly inspection to feel at ease. If even the label is gone, check the history of this pump to see if it has been used at such temperatures before. Also, take a look at the utilization rate of this pump; if it’s not high, keep it as is. If it’s a critical component, it would be better to replace it with a modern version. The key question is whether this pump has been used under raw material conditions of 330°C. It can be used if it has been used before. Don’t consider others’.
Replace the pump. It will be used frequently in future work, so spare parts need to be properly managed.
Use steam as a cover, then test the vehicle at a low flow rate. Based on the test run results, consider whether it can be used for a long period of time. The biggest requirement in the current environment is safety. Check at this temperature whether a leak could cause a fire.
