Due to the different working conditions, viscosity and abrasiveness of the conveyed media, the lobe pump outlet speed chosen is also different, today Ace lobe pump's compile some common examples for you.
1、Gasoline, diesel unloading
Petrol, diesel is clearer than water, the temperature rises, easy to vaporize, so when the speed is high, control at 420rpm, the outlet needs to be equipped with a safety valve, one is to prevent cavitation pump vibration, one is to protect the pipeline.
2. Tank bottom sludge
The oil sludge at the bottom of the tank is corrosive and abrasive, so the rotational speed needs to be controlled at a lower level, between 300-350rpm, to ensure self-priming capacity and reduce the consumption of wearing parts by the medium.
3. High density pond sludge
The residual sludge, return sludge, needs to be kept at 400rpm depending on the solids content, generally, and in some cases with long running times, controlled at between 300-350rpm.
Oily sewage ponds are gradually being closed for environmental reasons and lobe pumps are gradually replacing submersible pumps, with the outlet speed generally kept between 300-350rpm to ensure self-priming 6m
5、Other pump truck packages
Matching with other pump trucks, such as suction trucks and sprinkler trucks, which have higher requirements for self-priming, non-clogging and simple maintenance, in this case, keeping the speed at 350rpm-400rpm can meet the technical requirements and at the same time reduce the maintenance and use costs at a later stage.
