I designed an impeller is driven by hydraulic, and now know the water has just come in the pressure and flow of water, then how to know the speed of the impeller shaft, as well as power? At this point, the impeller shaft is the force and how much?
If the equipment has a separate lubrication station, the lubricating oil shall be checked regularly, depending on the result of lubricating oil test or replacement of lubricating oil. Add points: Lubricants general centrifugal pump with 46# hydraulic oil, piston pump with 68# hydraulic oil, etc.. Usually replaced three months.
Screw pump, screw pump is a displacement pump. According to the specific use of lubricating oil for general pump using temperature, speed and load, like 45# 100# and so on, if the oil filling equipment of the quantity is less, the replacement of a detection half generally do not usually check the lubricating oil, lubricating oil emulsification, prevent deterioration or lack of,
I used to try to answer your question and the single impeller centrifugal pump impeller, pump head is mainly of different requirements, generally single impeller centrifugal pump head is lower than the double impeller centrifugal pump, the use of screw pump, flow of general medium viscosity is large or medium is not good
