Diesel pump required for screw compressors
Thread Content
Our company has a screw compressor equipped with a gas holder, and diesel injection is required at its inlet. A 2-liter diesel storage tank has been installed outside the compressor building; a transfer pump is needed to deliver diesel to the inlet of the screw compressor. The requirements for this pump are a pressure of 0.3 MPa and a flow rate of 6 liters per hour. Which type of diesel pump should be chosen? Centrifugal pump (with what type of seal flushing system?), gear pump, screw pump, electromagnetic pump, or shielded pump – which one is the best choice?
The gear pump we use is okay~
We use vertical pipeline centrifugal pumps, and no mechanical seal flushing is required； It’s originally an auxiliary pump; adding another auxiliary system to it makes things too complicated and increases the risk of problems. It should also be noted that our diesel pump is used during the startup phase; once the oil-gas separator reaches a certain pressure, an interlock mechanism shuts down the diesel pump, and the pressure in the oil-gas separator is then used to push the diesel to the compressor inlet. I’m not sure how yours is set up.
It’s the same for us; the model provided by the design institute is also a pipeline centrifugal pump
